I've been working on transferring some Video8 tapes. I did an initial pass over Firewire using a Sony Digital8 camcorder. During the transfer process, I encountered an issue with many of the tapes where the tracking would progressively degrade over a period of perhaps 15-60 seconds. It would start with some horizontal dashed "snow", which would intensify gradually until the video became a rainbow blob of noise. The video and audio would eventually drop out entirely.
I tried cleaning the heads and visually inspecting the tapes and I found no obvious cause for the issue. I often found that rewinding the tape a bit and restarting playback, or sometimes just giving the camera a slight whack, would fix playback for a bit, but the problem would always reappear. Some of the tapes I had to transfer in ~5-minute snippets because of this issue. In the end, I chalked it up to a bad camera.
Dissatisfied with the DV25 encoding of the initial Firewire transfer, I got a second Digital8 camera (DCR-TRV340) in excellent condition and decided to repeat the transfer process over S-video. The first tape went fine. But on the second tape, I hit the exact same issue. So now I'm thinking... is the issue my tapes?
I wondered if the camera that originally recorded this might have been out of alignment, or if this could be "sticky shed" causing a head clog... but then why wouldn't this resolve after head cleaning?
I welcome any insights on what may be causing this issue, and how I can address it to successfully transfer my videos! Thanks!!
Attaching a video segment (sound removed) and a few representative stills showing the issue.
It's clearly a single head clog. Your video sample has been deinterlaced, and every other field shows a clear picture, while the middle fields present snow, typical of a single head clog. If a cleaning tape doesn't solve it, try playing/fast forwarding a new tape, or take it to a technician with experience in these video cameras for a manual cleaning of the heads as the dirt is seemingly so deeply entrenched into the head that a regular cleaning tape is not enough. Additionally, it seems your tapes are the culprit and won't stop shedding, so baking them isn't out of question as themaster1 suggested, before clogging the head again.
Agree with others, this almost certainly a head clog. Depending on the tape formulation, you might have more difficulty getting the residue off than most other tape types if it happens to be a "Metal" formulation tape, though a "cleaning tape" that is very slightly abrasive should work. Those tapes can be pretty expensive these days though. Never hurts to try the paper/alcohol method to clean the video head first, but camcorders are pretty hard to get into with your fingers to manually rotate the head to do it.

Why? It just 2 screws to remove head cover (on all camcorders). Do not try to clean head through loader Cleaning cassettes is not a solution, it can help at first sight, but really they clean nothing, simply pushing all dust and debris around.

Depends on the model of camcorder, the ones that load from the top aren't too bad to get at, but the ones that load from the bottom are harder because there's an extra metal cage that doesn't come off with the cover.
The original poster does happen to have one of those bottom loaders (TRV-340). This is an TRV-350, but you can see in the photo that there's a metal plate with holes in it that doesn't come off with the plastic cover. It is possible to cut a few things to get at the head on that style from the top, but most users that have never taken one of these apart probably aren't planning on going that route if it can be avoided.
This is a common issues for Hi8/Video8, with a common fix.
Shout-out to @NJRoadfan (I think) for sharing this here years ago.
- Take an already-captured tape, that captured well.
- Put it in the camera.
- REW (or FF) the entire tape
- Do it again, but the other direction FF (or REW)
- Eject
Now take the bad/snow tape, play it again. Is there picture?
- If not, repeat the above.
- If so, get back to capturing, back to work.
Completely dismantling the camera for a cleaning is not required. And this will probably happen, multiple times, on that stack of tapes you're converting.
A late thank-you for this tip. The rewind/fast-forward trick with a known-good tape seems to work quite well, although I do need to repeat it fairly often while capturing certain "clog-happy" tapes. This seems to work much more reliably for me than manually swabbing the heads.

Manual cleaning won't work because 8mm videotape contains metal particles, and alcohol doesn't dissolve metal. You need to literally grind the clog off the heads via abrasion. A few minutes of fast-winding a tape will do it, but so will ~10 seconds of playing a dry-type head cleaning tape. Or if you're fearless like 12voltvids, you can just hold your fingernail against the heads for a few seconds to do it!

Gah!
As times goes by, more and more, that guy is proving himself to be an idiot. Seriously, finger oils on a head drum? Those oils transfer to the tapes, then start to further degrade the tapes.
He spews so much misinformation lately, especially regarding S-VHS VCRs, s-video, etc.
In this very video, you can see how rough he is with gear. There's simply no excuse for that.
He does a huge disservice to this entire niche/field/industry. Too much bad advice, and too often leading with bad examples.
