How to convert VHS tapes to digital yourself.

To convert VHS tapes to digital at home you need a working VCR, a USB capture stick, a computer and OBS Studio, which is free. Join the VCR’s yellow, white and red outputs to the stick, record in OBS at 720 × 576 and 25 frames a second while the tape plays, then correct the picture shape with one FFmpeg command. The tape plays in real time, so a three-hour tape takes three hours.

Good enough for what?

This guide is for reliving old memories: getting the school concert, the wedding and the family Christmas off the tape and onto a screen, with the essence of them intact, and doing it cheaply. For that job, good enough is good enough. VHS holds much less detail than people remember, and a modest capture stick records nearly all of what a VCR puts out. You don’t have to take that on trust: the two sample transfers on our media transfer page were captured with this stick and these settings, and the full-quality files are there to download.

It is easy to lose months reading about the best possible transfer and never start. When the aim is to watch it again and share it with the family, the gap between this setup and a rack of professional gear is small next to the gap between having the file and not having it. Tapes fade a little more every year, so a good capture made this year is worth more than a perfect one that never happens.

There isn’t a better time than now. The usual estimate for a VHS tape is 10 to 30 years before the recording has noticeably faded, and that is for a tape stored well, somewhere cool and dry. A wedding filmed in 1995 is already past it. A tape that age usually still plays, but it is on borrowed time, and so are the machines: nobody makes VCRs any more, and working ones get scarcer every year. Australia’s National Film and Sound Archive put a date on the problem for its own collection in Deadline 2025, warning that tape not digitised by 2025 would in most cases be lost.

The three levels of VHS transfer

There are three basic ways to get a VHS tape into a computer, and each costs a good deal more than the one before. This guide is level 1.

Levels 1 and 2 both capture through an adapter, and that is how the trade works too. Commercial VHS-to-digital services capture through adapters, not straight off the RF. What separates a careful transfer from a careless one at these levels is mostly the condition of the VCR, the settings and the checking, all of which are covered below.

Archival grade is another level, and this guide doesn’t pretend to reach it. The sections near the end explain what the higher levels involve: time base correctors and S-VHS decks and better capture devices for level 2, and RF capture for level 3. If one or two of your tapes deserve more, capture them at level 1 now so you have something to watch, and keep the tapes so the better transfer is still possible later.

What you need

• A working VCR. It needs line-out sockets on the back: yellow for picture, white and red for sound. Test it first with a tape you don’t care about.
• A USB capture stick. This turns the VCR’s analogue signal into something a computer can record. Ours is below.
• A yellow-white-red RCA lead to join the two, if the one that came with the VCR is long gone.
• A computer with a spare USB port and room on the drive. Allow 5 GB for each hour of tape.
• OBS Studio and FFmpeg. Both are free. OBS does the recording and FFmpeg fixes the picture shape afterwards.

USB capture stick

DIGITNOW! USB audio and video capture card

What we use it for: capturing VHS. The VCR plugs into one end, the computer into the other, and the picture and sound arrive in OBS like a webcam and a microphone would.

Inputs

Composite video, stereo audio, S-Video

Captures

720 × 576 at 25 fps (PAL)

Connects by

USB

Driver

None needed on our Windows 11 PC

Know before you buy: it has no time base corrector, so a worn or wobbly tape is captured exactly as wobbly as the VCR plays it (what that means). We ignore whatever software comes in the box and record with OBS. We have only used ours on Windows, so we can’t vouch for it on a Mac.

Not sure which socket is which on the back of the VCR? The connector reference has drawings of RCA plugs with their colour code, S-Video and SCART.

Before any tape goes in: check for mould

Hold each cassette under a bright light and look through the clear window at the edges of the wound tape. White, grey or brownish powder, fuzzy spots or fine threads on the tape pack are mould. Tapes kept in a garage, a shed or under the house are the usual victims.

Don’t play a mouldy tape, not even to see what’s on it. The mould rubs off onto the VCR’s heads and guides and from there onto every tape you play afterwards. It can also stick layers of tape together, so the tape tears as it unwinds. Put the tape in a sealed bag, away from the others, and clean it or have it cleaned before it goes near a machine.

Cleaning mouldy tape is a job in its own right, with its own precautions (the spores are not something to breathe in), and we don’t cover it here. The National Archives of Australia’s advice on preserving magnetic media is a sound place to start, and there are detailed guides elsewhere written by people who do it every week.

Get comfortable with the cassette itself

A VHS cassette is not a sealed mystery. Five Phillips screws on the underside hold the shell together (one is sometimes hidden under a label), and once the top half lifts off you can see how the tape runs from one reel to the other. Being willing to open one is what turns a “ruined” tape into a recoverable one: a snapped tape can be joined, a tape that has come off its reel can be re-attached, and reels from a cracked or jammed shell can be moved into a good one.

Practise first on tapes you don’t mind damaging. A couple of op-shop cassettes are ideal. Take a photo of the inside before you move anything, because the door spring and the reel locks are easier to put back when you can see where they were.

To repair a snap:

1. Trim both broken ends square with sharp scissors, cutting away any crumpled tape.
2. Lay the two ends end to end. They should meet without overlapping and without a gap.
3. Stick a small piece of clear sticky tape (Scotch tape) across the join, on the back of the tape only. The back is the side that faces into the cassette; the outer side is the one the heads read.
4. Press it down firmly, then trim the sticky tape flush with both edges of the video tape so no adhesive hangs over.

You lose a second or two of picture at the join. Proper splicing tape is the better material if you expect to do this more than once, but ordinary sticky tape is enough to get a tape through one capture. Treat a spliced tape as single-use: play it once, to capture it, and handle the tape itself as little as you can, with clean hands. iFixit has a photo guide to opening and repairing a VHS cassette if you want to see each step.

Step 1: Connect the VCR to the computer

1. Plug the RCA lead into the VCR’s line out (sometimes labelled AV OUT): yellow to yellow, white to white, red to red. If the VCR has only a wide SCART socket, a SCART-to-RCA adapter switched to “out” gives you the same three sockets.
2. Plug the other ends into the matching colours on the capture stick.
3. Plug the stick into the computer. On our Windows 11 PC it needed no driver and appeared as two devices: “USB Video” and “USB Digital Audio”.

A mono VCR has only one audio socket, usually white. Connect that and leave red empty; step 3 covers the setting that puts the sound in both ears.

Step 2: Set up OBS Studio

Download OBS Studio from obsproject.com and install it. It is made for live streaming, which is why it has far more buttons than this job needs. What you enter in Settings depends on two things: which television system the tape was recorded in, and how big a file you are prepared to keep.

PAL or NTSC?

Tapes recorded in Australia, New Zealand, the UK and most of Europe are PAL: 576 lines of picture at 25 frames a second. Tapes from North America and Japan are NTSC: 480 lines at 29.97 frames a second. The settings below cover both.

An NTSC tape also needs a VCR that can play it. Many Australian VCRs will, but some put out a hybrid signal meant for PAL televisions, which a capture stick may show in black and white or not at all. A multi-system VCR that puts out true NTSC is the reliable choice. We have only captured PAL tapes ourselves, so the NTSC columns are the standard numbers for that system, not something we have tested on our stick.

High quality or maximum?

OBS’s Recording Quality setting has two choices worth using for tape.

• High Quality, Medium File Size is what we use. It compresses the picture with H.264 to a level where the losses are hard to find on VHS, and a tape comes out at a few gigabytes an hour.
• Lossless Quality, Tremendously Large File Size is the most OBS offers. Nothing is thrown away once the picture has been captured. OBS warns you about the file sizes when you choose it, and it means it: when we ran the same lossless codec over one of our VHS samples, it worked out at 20 to 30 GB an hour.

Between the two sits Indistinguishable Quality, Large File Size, if you want a margin without the lossless file sizes. And lossless here only means OBS adds no losses of its own. It doesn’t turn a level 1 capture into a level 2 one: the stick, the yellow lead and the deinterlacing are all the same.

The four sets of settings

Pick the column that matches your tape and your disk, and change only these:

Those numbers are not arbitrary. Australian VHS is PAL, which is 576 lines at 25 frames a second, and 720 × 576 is the standard way to store it; NTSC is 480 lines at 29.97, stored as 720 × 480. Recording at exactly that size means OBS never rescales the picture. MKV is the safe container: if the computer crashes two hours into a tape, an MKV file keeps everything recorded up to that moment, where an MP4 can be lost entirely.

Step 3: Add the VCR as a source

1. In the Sources box, click + and choose Video Capture Device. Pick the stick as the device (“USB Video” on ours), set Resolution/FPS Type to Custom, the resolution to 720x576 and the FPS to 25. For an NTSC tape, use 720x480 and 29.97.
2. Right-click the new source, choose Deinterlacing and pick Yadif. VHS draws each frame as two half-pictures a fiftieth of a second apart (a sixtieth for NTSC); without this, anything that moves gets comb-like edges. Our lesson on interlaced video and deinterlacing explains what this setting does and what it costs.
3. Click + again and choose Audio Input Capture. Pick the stick’s audio device (“USB Digital Audio” on ours).
4. Open Settings › Audio and, under Global Audio Devices, set Desktop Audio and Mic/Auxiliary Audio to Disabled. OBS switches both on by default, and while they are on, every Windows notification sound and whatever the computer’s microphone hears in the room is recorded over the top of your tape. Afterwards the only meter left in the Audio Mixer should be the stick’s.
5. For a mono VCR, open the menu beside that source in the Audio Mixer, choose Advanced Audio Properties and tick Mono, so the sound comes out of both speakers.

Press play on the VCR. You should see the picture in OBS and the audio meter moving. If the picture fills the preview edge to edge, the sizes are right.

Step 4: Record one minute and check it

Before committing three hours to a tape, click Start Recording, let a minute go by, click Stop Recording and play the file back. Check three things: the picture is steady, the sound is there in both ears, and it stays in time with people’s lips. If the picture rolls or shows snow along the bottom, adjust the VCR’s tracking control and try again.

Step 5: Record the tape

1. Close every other program, including the ones sitting in the background: browsers, chat apps, cloud sync, anything about to run a scan or an update. On a laptop, plug in the charger.
2. Rewind the tape to the start.
3. Click Start Recording in OBS first, then press play on the VCR. Trimming a few blank seconds later is easier than missing the opening.
4. Let it run. The capture happens in real time, so leave the computer to do its thing and switch off sleep mode for the evening.
5. When the tape ends, click Stop Recording. The file is in your Videos folder unless you chose somewhere else.

Closing everything else is not superstition. OBS compresses the picture as it arrives, and it only gets one go at each frame. If another program grabs the processor or the disk at the wrong moment, OBS can’t keep up and frames go missing for good, which shows up as a stutter in the finished file. A modern computer has plenty in reserve for a picture this small, so think of it as cheap insurance. To check, open OBS’s Stats window (under Docks in recent versions) before you stop the recording: Skipped frames due to encoding lag and Frames missed due to rendering lag should both read 0, or very close to it.

At the high-quality settings our own PAL captures came out between about 1.4 and 4.6 GB for each hour of tape. Noisy, worn recordings make bigger files than clean ones. At the maximum settings, allow 40 GB an hour.

Step 6: Fix the picture shape

This is the step most guides leave out. A PAL picture is stored as 720 × 576 pixels that are each slightly wider than they are tall, and it is meant to be shown at 4:3. OBS has no setting for that, so it labels the pixels as square, and every player then shows your capture at 5:4. Everyone looks about 6 per cent too thin.

The picture itself is fine; only the label is wrong. FFmpeg can correct the label without touching the video. Install it (on Windows, winget install Gyan.FFmpeg in a terminal; on a Mac, brew install ffmpeg), then run:

ffmpeg -i "tape.mkv" -c copy -aspect 4:3 "tape-4x3.mkv"

The -c copy part tells FFmpeg to copy the picture and sound exactly as they are, so nothing is re-encoded and no quality is lost. It takes seconds, even for a three-hour tape. Check the new file plays at the right shape, then keep it as your master and delete the original.

NTSC tapes have the opposite problem and the same cure. The picture is stored as 720 × 480 pixels that are each slightly narrower than they are tall, so an unlabelled capture shows at 3:2 and everyone looks a little too wide. The command above sets it to 4:3 in exactly the same way.

If you recorded at the maximum setting, the file is an AVI, and AVI has no dependable place to keep that label. Give FFmpeg the AVI and have it write an MKV instead:

ffmpeg -i "tape.avi" -c copy -aspect 4:3 "tape-4x3.mkv"

The lossless picture and sound are copied across bit for bit; only the container around them changes.

Step 7: Make a copy that plays anywhere

The MKV is the copy to keep. Phones, TVs and messaging apps are happier with MP4, so make a second, smaller file to share:

ffmpeg -i "tape-4x3.mkv" -vf "scale=768:576,setsar=1" -c:v libx264 -crf 21 -preset slow -c:a aac -b:a 128k -movflags +faststart "tape.mp4"

That resizes the picture to 768 × 576 with square pixels, which every device displays correctly, and it is how we make the web previews on our own samples. For an NTSC tape, write scale=640:480 in place of scale=768:576. Always make the MP4 from the MKV, and keep the MKV.

Step 8: Back it up, and keep the tape

A capture that lives on one drive is one failure away from gone. Put the MKV in at least two places, such as the computer and an external drive, or an external drive and cloud storage you control. Give the files names you will recognise in ten years, with the year and the occasion. And keep the tapes somewhere cool and dry: capture methods keep improving, and you may want to do the important ones again.

What level 1 won’t give you

• No time base corrector. This is the big one. A good tape captures well without it; a worn one shows wobbling verticals and a bent top edge, and a badly damaged stretch can drop frames or let the sound drift out of time. The next section explains what a time base corrector is and how to tell whether a tape needs one.
• The VCR matters more than the stick. Dirty or worn heads give a soft, noisy picture that no capture device can improve. If every tape looks bad, suspect the VCR.
• No clean-up. Nothing here removes noise, steadies the picture or corrects colour. What the tape holds is what the file holds.
• Copy-protected tapes misbehave. Many shop-bought movies carry copy protection that makes a capture pulse bright and dark. This guide is for your own home recordings.
• It takes real time and some attention. Twenty tapes is twenty evenings, plus the tapes that need a second go.

What a time base corrector is, and what it does

“Time base” is the timing of a video signal. A PAL picture is sent one line at a time: 625 lines to a frame, 25 frames a second, so a new line starts every 64 millionths of a second. Each line opens with a short sync pulse that says “a new line starts here”, and whatever is receiving the signal relies on those pulses arriving on schedule.

A TV station or a DVD player times those pulses with a quartz crystal, and they are as good as perfect. A VCR’s timing comes from mechanics: a head drum spinning 25 times a second and a ribbon of plastic being pulled past it. The drum’s speed hunts a little, the tape stretches and shrinks with age and temperature, and its tension changes as one reel empties and the other fills. So each line comes off the tape slightly early or slightly late, and the error is different on every line. That is time base error, and every VHS tape has some.

The errors are tiny, but so are the pixels. A capture device samples 720 points across each line, about 74 billionths of a second apart. A line that arrives one millionth of a second late lands about 13 pixels to the right of the line above it.

Tape still looked fine on the family TV because an old tube television follows the wobble. It restarts its sweep on each sync pulse as the pulse arrives, so the picture holds together. A capture device has a harder job: it has to turn that unsteady stream into a fixed grid of pixels, with every line starting in the same column. The chip in an inexpensive capture stick follows a healthy tape well and a struggling tape badly.

What a TBC does

A time base corrector is a buffer with a steady clock. It reads the picture into memory as it arrives, wobble and all, works out where each line really begins, and plays the lines back out on a clean, crystal-timed schedule with fresh sync pulses. The picture content is unchanged; only its timing is repaired. There are two kinds, and they fix different things.

• A line TBC holds a few lines at a time and straightens the errors within the picture: wiggling edges and the bent top. It is built into the better S-VHS decks from JVC and Panasonic, where it corrects the signal as it comes off the tape. Some older DVD recorders do the same to anything passed through them, which is why enthusiasts wire one in between the VCR and the capture device.
• A frame TBC, or frame synchroniser, holds a whole picture and sends out a completely regenerated, steady signal. It does little for wiggles inside the picture, but the capture device never loses its place, so no frames are dropped and the sound stays in time over a long tape. These are stand-alone boxes, long out of production and expensive second-hand.

The fussiest setups use both, a line TBC in the deck and a frame TBC after it. The RF capture route described below does the same correction in software instead.

What it doesn’t do

A TBC fixes timing and nothing else. It adds no detail, and it doesn’t remove noise (decks often pair it with a separate noise reduction circuit, which is where that reputation comes from). It can’t repair dropouts, the white streaks where the tape’s coating has flaked away, and it can’t fix a tracking problem or a tape too damaged for the VCR to play.

How to tell whether a tape needs one

Look at your one-minute test from step 4 for these signs:

• vertical edges that shimmer or wiggle: door frames, window frames, on-screen titles
• the top of the picture bending or hooking to one side
• the picture jumping, rolling or breaking up for a moment
• on a long capture, sound that slowly drifts out of step with the picture

If the edges stand straight and the sound stays in time, that tape doesn’t need a TBC, and most first-generation home recordings in decent condition don’t. The tapes that struggle are usually copies of copies, long-play recordings, camcorder footage, and anything stored somewhere hot or damp. A sensible plan is to capture the easy tapes yourself and set the difficult few aside; those are the ones worth spending money on.

Level 2: what an S-VHS deck is, and why people want one

S-VHS, short for Super VHS, was JVC’s 1987 upgrade to the format. It uses the same size cassette with a better grade of tape, and it records the brightness part of the picture with a wider signal: about 400 lines of detail across the screen, where ordinary VHS manages about 240. Colour is recorded the same way as before. An S-VHS recording won’t play properly in most ordinary VCRs, which is one reason the format stayed with enthusiasts and professionals, and why your box of family tapes almost certainly holds none.

So the interest today isn’t in S-VHS tapes. It is in the machines, because an S-VHS deck plays ordinary VHS tapes too, and these were the top-of-the-range models. They tend to bring three things:

• An S-Video output. VHS stores brightness and colour separately on the tape. An ordinary VCR mixes the two into one signal for the yellow lead, and the capture device then has to pull them apart again, which it never does perfectly: fine patterns shimmer with false colour, and coloured edges crawl with dots. The S-Video socket sends brightness and colour down separate wires, so they are never mixed in the first place. This helps ordinary VHS tapes just as much as S-VHS ones. Sound still travels on the red and white leads. Ordinary VHS decks almost never have this socket. DVD and VCR combo units often do, but check before relying on it: on some the S-Video socket carries the DVD side only (it may be labelled “DVD exclusive out”) and the tape still comes out of the yellow one, while on others, mostly the DVD-recorder combos, it carries the tape as well.
• A built-in line TBC on the better models, usually paired with noise reduction. This is the time base corrector described above, working inside the deck.
• Better mechanics and electronics. They were built to a higher standard than the family VCR, and a machine in good order tracks and plays a marginal tape more steadily.

What an S-VHS deck can’t do is put detail into a VHS tape that was never recorded there. A VHS tape played on one still holds about 240 lines. You get a cleaner, steadier version of what is on the tape, not a sharper one.

The catch is that these decks are decades old and sought after. They sell for many times what an ordinary VCR does, and one that has sat unused often needs servicing before it can be trusted with a tape. For a box of family recordings in good condition, the VCR you already have is the good-enough choice. An S-VHS deck earns its keep on difficult tapes, or when there are a lot of them. If you do get one, connect it by S-Video; the capture stick above has an S-Video input for exactly this.

The other half of level 2: a better capture device

The chip inside an inexpensive capture stick is basic. Dearer capture devices earn their price in three ways:

• They hold onto an unsteady signal. A higher-grade video chip keeps its place on a tape that makes a cheap stick drop frames.
• They leave the picture alone. Cheap sticks often adjust brightness and contrast on their own as the scene changes, and that can’t be undone afterwards.
• They can record losslessly. With capture software such as VirtualDub, a better device records every frame exactly as it was digitised, with the two half-pictures of each frame kept intact, so nothing is thrown away and the tidying up can be done later, and done again when the tools improve. The cost is disk space: tens of gigabytes for each hour of tape.

A better capture device behind an ordinary VCR is a modest upgrade. Paired with an S-VHS deck and its S-Video output, it is what level 2 means.

Level 3: RF capture, straight off the heads

The best archival copy of a VHS tape isn’t a video capture at all. RF capture records the raw signal straight off the VCR’s video heads, before the VCR’s own electronics have turned it into a picture. Open-source software, vhs-decode, then does the decoding on a computer, time base correction included, and it can be run again on the same capture as the software improves. Nothing the heads read is thrown away.

RF stands for radio frequency. A VCR doesn’t put the picture on tape as a video signal. It records a carrier wave of a few million cycles a second, whose frequency rises and falls with the brightness of the picture, which is the same principle as FM radio. Engineers call a signal in that range RF, even though this one never goes near an aerial. Playing a tape means reading that carrier off the heads and turning it back into video, and an RF capture takes the signal just before that step.

Not to be confused with the RF socket on the back. Many VCRs have an antenna socket labelled RF, RF OUT or ANT. That one carries the finished picture re-broadcast on a TV channel, for televisions with no other input, and it is the worst output the machine has. RF capture has nothing to do with it: the signal is taken from inside the VCR, at the heads.

It is also a serious project. You open the VCR and tap test points on its circuit board, you need a dedicated capture card, and the raw files run to a couple of gigabytes a minute before compression. Most people don’t do it, and nor do commercial VHS-to-digital services: they capture through adapters, the same basic method as this guide. For a tape that truly matters it is worth knowing the option exists. For the rest of the box, the method on this page will do nicely.
