    What's a bad cap?

  2. There are drops/duplicates in your capture process.

    By the way, you can alternatively use:
    Code:
    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:

    https://www.digitalfaq.com/forum/video-capture/15246-pinnacle-card-works.html

    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.

    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.

    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

    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.

    I've edited my previous post.
    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).

    @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.

    Here is the JVC going into the s-video of the black magic. Black magic said 8bit avi

    This looks correct from a capture point of view: YUV 4:2:2 interlaced BFF, 29.97fps. (Blackmagic seems to capture NTSC with 486 lines).
    There are however some glitches at the bottom of some of the frames (too much for head switching garbage I think). Maybe this is baked into the tape and not related to the capturing process. Not sure. Is this from an edited/dubbed tape?

    (Sidenote: The luma histogram has regular gaps. Probably due to the luma expansion by the capture SW to fill the 16....235 range.)

    This was from my wedding tape. Some company made this from video they gathered that day. I will capture some different tapes. I’m wondering which device to use. The black magic or iodata. Would it be worth a shot to get an es15 and see if that clears up stuff with the jvc tbc off or is that just a waste? If the settings are ok and it’s as good as it gets, until after to try to clean up with software, do I just capture all my tapes and then process? I am trying to figure out this avisynth thing and first me, it’s tuff. Is there one with all the needed presets set to go that I can just download and run? I’ve tried hybrid but I can’t seem to find certain things and how to run really.
    With iodata what’s the best codec to use? Not sure if the magicyuv is worth the cost?
    Thanks for the help

    So it has been edited and copied. That explains most of the quality issues

    Try both and compare.

    I have my doubts

    Attached a script for deinterlacing your clip, then encoded for 4:3 aspect ratio. There is a learning curve though for Avisynth. You may get away with a simpler solution.
    With iodata what’s the best codec to use?
    Basically any of those lossless codecs mentioned before is as good as the other for lossless capturing.

    Script (video only):
    Code:
    AVISource("JVC into black magic s-vid.avi")
    ConvertToYV16(interlaced=true)
    AssumeBFF()
    QTGMC()  #or use a simpler deinterlacer
    Crop(8, 2, -8, -4)  #crop to 704x480
    TemporalDegrain2() #denoise, or use a simpler denoiser, or skip it
    ConvertToYV12() #for subsequent x264 4:2:0 encoding
    now encode it using x264

    So the dvdo went back to the black hole in my garage. I captured a few tapes via iodata and UT Video,ULY2 as the codec. No dropped frames that I can see, but maybe a few duplicates that seemed to have happened when the tape go crappy. That being said, the don't seem to open in davinci. I'm tried using shutter encoder, Avidemux, and virtdub2 and change it to .mov or .mkv and all they do is leave me with an audio file? How can I get them in there to edit? Did I pick the wrong codec? Where do I go from here? They play fine with vlc player after capturing.
    Thanks again.

    Oops, Davinci (Resolve, I assume) won't open the normally-used lossless AVI codecs, according to this document.

    A Davinci user will hopefully point you in the right direction. You might have to transcode to a suitable codec such as ProRes.

    Vegas will open files encoded with UTCodec. For DaVinci, you can transcode to H265 lossless using Vdub. Or ProRes (ffmpeg -i source.avi -c:v ks_prores -profile:v 4444xq out.mov).

    Please note that these will be BT601 files, not BT709.

  22. @Riker0007: You can convert your captured .avi to ProRes .mov using ffmpeg, like
    Code:
    ffmpeg.exe -i "your.avi" -c:a copy -c:v prores_ks -profile:v 2 -bits_per_mb 8000 -pix_fmt yuv422p10le -vf scale=interl=1,setfield=bff "proRes422.mov"
    If you don't insist on DaVinci you can try the free Shotcut which opens your .avi without problems.

    Added:
    Here your source of post#45 converted to ProRes, using the ffmpeg commandline. It should open in DaVinci.
