Ask Slashdot: Best Service To Digitize VHS Home Movies?

An anonymous reader writes Could someone recommend a service to convert old VHS home movies to a lossless archival format such as FFV1? The file format needs to be lossless so I can edit and convert the files with less generation loss, it needs 4:1:1 or better chroma subsampling in order to get the full color resolution from the source tapes, and preferably it should have more than 8 bits per channel of color in order to avoid banding while correcting things like color, brightness, and contrast.

So far, the best VHS archival services I've found use either the DV codec or QuickTime Pro-Res, both of which are lossy.

Do it yourself?

[kheldan]

If the overall quality is a high priority to you then why not get a decent video capture device and do it yourself? By the way, if it's all on analog video tape like VHS, isn't it going to have degraded somewhat all by itself over time anyway? I've still got some VHS tapes I recorded myself that are at least 10 years old, and a high-end Sony VCR I kept (used to have two) and even though they were brand-new 'broadcast quality' tapes recorded at 2-hour speed, they really don't look all that great now. Honestly if it were I, and it was that important, I'd get a good video capture device, capture it all to the most uncompressed format I could, and do the editing myself.

There have also been problems with the viability of format-conversion businesses, and many have closed their doors after having been paid by their customers and received their customers' tapes, and often because of property lease agreements and failure to maintain the lease, the business owner gets locked out and can't even get access to return customers' tapes even if he wants to.

Like anything else, people thought they could make a quick buck doing what seems to be an easy process. Most of these places just hooked up a cheapo VCR to a run of the mill DVD recorder and hit record. The results were awful, over compressed, and filled with video dropouts. To do it right requires time and money, something that isn't going to happen at $10 a tape. Doing it yourself properly requires significant investment in hardware and time to get the capture setup "just right". Even the DIYers (like myself) will tell you that its cheaper to send them out to a qualified transfer service. In my case, I didn't have much of a choice since a few of my tapes were in Betamax format, something many transfer places don't handle.

In your shoes I'd do it myself, and as others have said I'd probably not be quite so picky about quality as you're being. If anything, you should spend your money looking for a commercial-grade VCR or a high-end consumer one with good audio, like a fancier S-VHS deck, to make the playback aspect of the copy as good as it can be.

This question came up on Ask Slashdot a few months ago. I'll repeat the list here

Recommended VCRs for transfer: http://www.digitalfaq.com/foru... Budget: $200-300
Note: They are a a transfer service, they have first hand experience with these decks. You'll see that everyone else recommends the same decks too.
Recommended capture cards: http://www.digitalfaq.com/foru... Budget: $25-50
AGP ATI All-in-Wonder cards can be had for about $30-40 with the required dongles and breakout boxes on ebay. Look for a decent Prescott P4 with an AGP slot at the thrift store or scrapper for your capture box. The cards require Windows XP as there is no official support in Vista/7. If you want to capture on your Windows 7 rig, try and find the ATI TV Wonder HD 600 USB. It has working drivers, and captures clean video with no AGC issues.
External TBC: http://www.digitalfaq.com/foru... $150-200
Used to keep capture cards happy. Many capture devices are sensitive to unstable video signals found on VHS tapes and either completely drop frames, or falsely flag the video as having Macrovision.

You can optionally pick up things like a proc-amp ($150-200 for a decent one) for correcting video levels. For software, capture with VirtualDub. For compressing video to MPEG-2, one of the better commercial codecs is MainConcept, although most go with TMPGEnc or open source codecs (HC-Enc, etc.). For DVD mastering, the old ULead DVD Workshop 2.0 does a great job.

Does the original magnetic tape have those propert

Does the original magnetic tape have those properties?

Unlikely unless it's S-VHS and even then, I don't think so if it was recorded on any normal household camera (quote from the Wiki: "In VHS, the chroma carrier is both severely bandlimited and rather noisy, a limitation that S-VHS does not address" - and they mention that S-VHS tapes were used to record 20-bit audio, but only if you were prepared to use several minutes of videotape for one minute of audio, so the chances that it recorded colour with even 8-bit accuracy is unlikely).

You have to think mathematically - significant digits. If the original only have 3 significant digits, there's absolutely NO POINT in worrying about anything with 3 or more significant digits handling it. All you're preserving is error anyway.

You know what? Digitise it yourself if you're that worried. Get a capture card (good luck finding one that captures RAW), plug it into a high-end VHS player, stick it all in 32-bit PNG channels if you want. The end result will be so insignificantly different to your original but will cost ORDERS OF MAGNITUDE more.

I'm with you on quality, I get that, and you want to get that stuff off tape sooner rather than later if it holds any kind of emotional significance to you (chances are, your holiday tapes from the 80's will never be played again once you're dead, and only a handful of times until then). But you're really trying to go too far because you've heard some things on audiophile/videophile websites and the like and think you have to do that.

You know what? The extra time spent with your family, and the extra money to follow the kid's hobbies, will more than make up for any theoretical loss in the MPEG encoding of some home movies. And, at the end of the day, so long as you can see who the people in the movie are and what's happening, who cares about the fine detail? You can't Bladerunner it back to 4K, so what you do now will not degrade in the future. And, chances are, what you do now is higher quality than anything on the original tapes anyway (unless you intend to capture the missing parts of the TV interlace somehow?).

Give it up. Buy a GBP20 adaptor from your local store. Buy a slide-and-film scanner while you're there. Have a night in with the family where you're all doing one job - scanning, sorting, cleaning, labelling, filing, archiving - and get everything you have in your archives digitised. Copy it to friends and family (who, honestly, really won't care but will be polite). Then forget about it until little Johnny is 18 and you want to embarrass him in front of his girlfriend.
