^ lol, what do you mean you just found it? On the ground?
Those USB IDs indicate it's the most common EasyCAP (EasyCRAP) out there; the EasyCap DC60 (Syntek STK1160 chip). I compared its quality using test patterns
here.
Note: I requested a sample of the now-working capture, because I'm considering buying this VCR model locally and I'd like to get a rough idea of how my tapes may look played through it. The OP was kind enough to provide a 7-second MP4.
VCR
Sharp VC-H960 = VC-H960U is a (North) American machine, NTSC format. There is no PAL variant with this part # scheme.

The sample MP4
It's 640x
480 @
50fps, encoded in progressive mode. This is a mix of standards, and should never happen.
You should capture
720x480 @
29.97fps, then
if desired* deinterlace to
59.94fps (double-frame-rate deinterlacing, aka "bobbing"). The MP4 sample is missing half the temporal information; the underlying frame rate is actually 30fps, with duplicates added to bring it up to 50fps.
I've attached a sample where I used the filter
TDecimate with option
Display = True and then re-compressed with x264. The Display option shows where the duplicate frames were detected and removed. They have metrics ~
0.3. Metrics for duplicates are typically <
0.5 depending on noise level of source, in my experience.
Short Avisynth script:
Code:
# Load video clip, with audio
V = FFVideoSource("clip.mp4")
A = FFAudioSource("clip.mp4")
AudioDub(V,A)
# Remove duplicate frames (remove 2 of 5; keep 3 of every 5)
TDecimate(cycleR=2,cycle=5,display=true)
* Depending on your chosen
delivery format,
playback devices, etc. it may make more sense to encode in
Interlaced mode, retaining
[a compressed version of] the original fields. This does not apply if you will only ever be sharing these using web-based players like YouTube, Facebook, Instagram, etc. In that case, definitely deinterlace and encode Progressive.
The saturation of this clip is also extremely low. Meaning: it's almost black-and-white. Maybe that's just how the camcorder recorded in this low-light situation.
I would appreciate it if you can attach a 720x480 @ 29.97fps clip of a TV recording or movie using this VCR (30 seconds or less, if in MP4 format).
Let me again say thank you for sticking around. I was really worried you'd be a
2-hit wonder.

- "Oh never mind, [SOLVED.]" Without explanation of specifically how, for others who might have the same problem in the future. This is my biggest pet peeve about Internet forums.
