Is it worth it recapturing videos?

[Riker0007]

Or slightly simpler:

LWLibavVideoSource("iodata.avi")
SelectOdd()
QTGMC() # optional deinterlace

Same glitches (caused by a bad cap).

What's a bad cap?

There are drops/duplicates in your capture process.

By the way, you can alternatively use:

LWLibavVideoSource("iodata.avi")
SelectEven()
AssumeTFF()
QTGMC() # optional deinterlace

The main problem is that you captured at 60 fps rather than 30 fps. So every field is duplicated and the field order is different for the even vs. odd frames. And in addition to that you have drop and duplicate frames. Capturing correctly at 30 fps will probably fix both those issues.

Got it. The dvdo will only allow me to capture at 59.9 frames via HDMI. The iodata I will redo . Thanks

I'm not sure which is better the iodata or a pinnacle?

Quality-wise, I reckon they're the same. Ease of use? Check this thread out for ease of use (NOT) of the 710-USB:

Do you think the gv-usb2 is bad?

Hard to say. That GV-USB2 clip is very short. And I've just noticed you're capturing in YUY2, which could be causing issues; you should be capturing to a lossless codec such as Lagarith, UT video or HUFYUV (all free). Have a look at my guide for capturing with AmaRecTV here. I mention those lossless codecs there.

If I'm reading your previous posts correctly, you're playing your tape with the VCR TBC off because it jitters. Generally, one needs a stabiliser of some kind, whether it be the VCR TBC, an ES-15 type DVD recorder or a full-blown, costly TBC. In your case, if you've got your VCR TBC off, you'll need one of the others. I have notes on stabilisers here, and the ES-15 specifically here.

First, try some other tapes with the GV. You can post samples here up to 500mb, so, with a lossless codec, a clip of 15 seconds would be better for analysis.

As for that DVDO, as @Sharc has pointed out, there's all sorts of issues there so I would steer clear of it for the time being.

I guess you didn't read that thread? That person has multiple variables at play, and troubleshooting thus far did not determine that the situation actually had anything to do with the Pinnacle card. Wiring or computer-side is more likely.

At least we can all still agree on total garbage, which is what HDMI adapters are.

[Alwyn]

No.

Prove it.

He should capture into YUV. His iodata.avi (GV-USB2 clip) is actually captured correctly into YUV 4:2:2 lossless (YUY2). Nothing to change in this respect. Just the framerate is wrong there.

[Sharc]

No.

Prove it.

The problem of the OP is not Pinnacle vs GV-USB2. It is usually more beneficial to teach (poor) drivers how to drive their car correctly rather than recommending them to change the car

[Alwyn]

He should capture into YUV. His iodata.avi (GV-USB2 clip) is actually captured correctly into YUV 4:2:2 lossless (YUY2). Nothing to change in this respect.

Oops, my bad, I meant not capturing to uncompressed/YUY2. I wouldn't have thought capturing uncompressed would be a good idea, bitrate and space-wise?

I've edited my previous post.

Actually, I don't. HDMI from Panasonic EZ-48 to Startech USB3HDCAP via splitter works just fine. I suspect that that DVDO is the problem.

Yes, the HDMI approach as experimented and documented by the German guys in their forum is a good alternative to the "standard" workflow https://gleitz-info.translate.goog/forum/index.php?thread/47572-tutorial-hochwertiges-..._x_tr_pto=wapp
In particolar when the tapes may benefit of the stronger intra-frame time base correction provided by specific DVD-Recorder devices.

Knowledgeable users Bogilein, oln and Skiller (among others) have demonstrated this in videohelp forums as well.

For clarification: uncompressed and lossless are not the same. YUV (YUY2) is already a form of compression based on the concept of luma+chroma. Capturing (digitizing) VHS as YUV 4:2:2 using a lossless codec like Huffyuv etc. is efficient as it prevents any undesired additional losses (for VHS). One could also capture less efficiently into YUV 4:4:4 or RGB for example, but for VHS it would be a waste of bandwidth/bitrate/filesize at no real benefit.

For RGB not only a bandwidth/bitrate/filesize loss, but also a useless signal manipulation because signal on tape is Y/C (more or less), as well as the architecture of the S-Video connectors out of the recommended VCRs (more or less).

[Alwyn]

@Sharc, so, for the benefit of the OP, confirm they should be capturing into one of the codecs mentioned, not "Uncompressed" in VDub or "YUY2" (or any of the "Y"s) in AmaRecTV.
