I've worked myself into paralysis on what (if any) extra hardware/software I need to get good results and what format I should capture to for editing.

Well, you've found this site, so hopefully the guesswork, gambling and time/money spent doing it is over with.

The Hi8 tapes were recorded on a Sony TR81 camcorder, which eventually broke. It had problems with the tension roller when some of the video was recorded. Most of the tapes play fine, but a few have bad horizontal jitter and some have tearing at the top. A few tapes have a horizontal tearing line that slowly moves from top to bottom (only at the end of the tape). A few parts have crinkled tape along the edge (which I don’t expect to recover).

Ewww, ugly. Unfortunately, unlike VHS formats, 8mm based formats are either good or bad. There's no way to "track" a bad 8mm tape -- it's basically an alignment issue, though more complicated than VHS alignment.
At least with VHS, you could purposely "break" (misalign) a machine, in hopes of getting the signal again. I just today sold an extra JVC VCR that has an ability to be "broken" in this manner without special tools.
Your only hope would be to misalign a Hi8 deck in the same way. But even that, that sometimes doesn't work.

This could possible be fixed in software, with a de-shake type of filter with heavy emphasis on the vertical noise. This same topic has been something we've research heavily in the past 6 months.
lordsmurf has asked about it in this thread on videohelp:
http://forum.videohelp.com/threads/3...uction-filters
and a good answer was given near the bottom at
http://forum.videohelp.com/threads/3...=1#post1933820 in the 14th post in that thread.
More examples of deshake and dejitter are found at
http://www.digitalfaq.com/forum/show...oved-1144.html -- using different methods.
The style of movement/jitter you have will determine the method of attack required. While the solution for AVI Synth is shown in that VH post, it's not necessarily better than the method not-yet-shared in the sample Dukes clips on this site.

While you may not be able to recover 100% of the signal, audio and portions of the video may be fine. I dealt with a project late last year where the VHS-C tape had significant damage from misalignment during recording. The solution was to crop the 4x3 video in a 16x9 widescreen version, cutting out the bad parts of the video. It turned out great, the client was quite happy with it.
Buzzing in the audio was filtered out using the methods discussed at

Just be clear on
what a TBC is, and how the various types of TBCs differ in what function they will perform for you. Read more at

I definitely need TBC. I was considering buying a Canopus ADVC55 or ADVC110, but after reading some of lordsmurf’s comments I’m not sure I want to go that route.

Yeah, a DV box is not a TBC, and the DV codec itself is not the
best compression format for capturing and archiving tape-based analog consumer/prosumer formats (VHS, S-VHS, 8mm, Hi8, etc). That was recently discussed in depth at

Instead I was thinking about using the hardware I have and adding an AVT8710 TBC. I'm willing to spend another ~$200 or so on hardware or editing S/W if it will make a difference.
|
Budget is workable.
AVT-8710 may or may not be your best buy at the moment. Let's see how this pans out before buying anything just yet.

It's alright, bottom-end device. I have one that I'm about to sell. Bought it for testing, and it mostly just aggravated me in the higher-end testing. It's basically the same as a cheap DVD recorder -- only on the computer, in terms of quality of output.

Gateway SX28000 Quad Core 2.3GHz 64bit 4G RAM; Win7 Pro (only has half height PCI so card selection is limited; has 4pin firewire, esata, and USB)

Good hardware for encoding speeds. The Win7 works against you, as will limited cards/ports.

Sony EV-S900 Hi8 Player (purchased from ebay, but produces great picture when used with good tapes).

As expected.

Decent home camera for shooting new videos, won't really affect capturing/converting your old videos.

1) Sony EV-S900 Hi8 Svideo -> Pinnacle 500-USB -> Gateway SX2800 (capture from the Pinnacle box using Pinnacle Studio 12 Ultimate)
GSpot says the container for the Pinnacle capture is DV Type 2 AVI; dvsd codec

The
AVT-8710 TBC would help for stabilizing any signal errors in this type of chain. Visual improvements would vary depending upon the errors present in the tape and errors fixed by the TBC.
Just to be clear, such a chain is Hi8 cam > TBC > capture box/card
Quote:
2) Sony EV-S900 Hi8 Svideo -> JVC Camcorder -> copy file to Gateway SX2800
GSpot says the container for the JVC file is DVD VOB format; MPEG-2 codec; 10080kb/s VBR
|
I would only do this at the equivalent at XP on a DVD recorder -- whatever the smallest amount of time is (best quality recording mode). Same as above for TBC.
Quote:
On the bad tapes capturing with the JVC camcorder dramatically improved the picture and eliminated almost all horizontal jitter. But it only slightly improved the scrolling horizontal line tearing. I assume the JVC must have some line TBC.
|
TBC, frame sync, both -- clearly it has some filtered going on for you, so that's good.
Quote:
But the problem is that the JVC only can record in .MOD files (encoded MPEG2).
|
Depending on the encode quality, it may not be an issue, especially at higher quality modes (lower compression). Then again, the MPEG files may not handle the hand-held video source well, nor would it necessarily edit/re-compress well later on.
Quote:
The other problem is that the JVC only has one channel audio-in (whereas the original tapes had stereo audio).
|
I doubt the tapes had true stereo. Most home cameras will at best record mono to both channels. It's still mono, just in both a L and R speaker. You need two separate mic inputs for true stereo, and it has to be mixed properly.
Quote:
But then the Pinnacle can only produce DV. I didn’t realize that this was also compressed format.
|
Yep, both 5:1 data rate and 4:1:1 colorspace compression.
Quote:
Is MPEG2 significantly worse than DV, if I am going to edit in Studio 12?
|
It can be, yes. It really depends on the source videos. If hand-held video, I'd say yes.
Quote:
Would I be better off adding an AVT8710 TBC than capturing to the JVC?
|
These are two difference devices, different purposes.
Quote:
Would the AVT processing cause audio/video synchronization problems?

No.
