  1. I thought I had everything figured out to find 7 tapes later there was an audio drift issue about 1 second delay at the end of a 2 hour tape.
    Days of testing later I come to find it's not a drift issue but a result of starting and stopping recording (camcorder) and is horrific if there is a gap in the recording like having perfect sync then a long 5 second gap, then 2 second delay.

    I can start a recording, press play, and get the initial sync to be at various points because of where head sync catches the tape I guess.

    So what gives??? How does this work? I've tried enabling and disabling all the sync settings to no avail.
    Why is this so difficult??? At least I figured out a solution to recording then encoding for archive in 30fps h264 interlaced format.

    Virtual Dub
    x264 compression > interlaced
    PCM Audio
    disabled overlay
    disabled audio preview
    all variations of sync settings.

    This VCR DVD burner combo with a broken burner (previous owner's cigarette tar on the lens) has all kinds of outputs including HDMI

    Is there a difference if I try using S-Video? I'd try it but my cables are at my parent's house.
    I might check out the HDMI and see what format it puts out for VHS if it even goes through the HDMI.

  2. Looks like the HDMI output is 480P 60 de-interlaced so it would be easy to capture and crop it with an HDMI capture card.
    I'm pretty sure 60p is a larger file than 60i so it's not as attractive but it's the format I was using previously before all this audio garbage.

    I would still like your feedback about how the audio/video sync works and why it's linked to how the tape is recorded.

    Virtualdub has a well know audio sync issue that develops over the course of the capture. I would suggest AmaRecTV 2.31 as the only replacement. It's what I switched to after I gave up on trying to fix Virtualdubs sync issues.

    I second the recommendation for AmaRecTV, but is there a reason you recommend that specific version, rather than a more recent one?

    Pretty sure the newest version wants you to pay for it while the older version is just fine.

    Oh, thanks - but I'm using 3.10 and haven't come across anything like that. (Hopefully I'm not in for a nasty surprise...) As long as there's no technical/stability reason, I'll stop worrying about it!

    Hmmm ok. I just remember someone saying something along the lines of the newest version had a pay wall of sorts or you had to use the AMV codec only but I never verified it for myself. If it works then certainly ignore me

    Uh ... no. No such thing exists.
    I've captured 8-hour tapes as lossless AVI, no dropped frames, no sync issues.
    Using quality JVC S-VHS (line TBC) + external DataVideo workflow, to good AIW capture card.

    Are you really this new to the forums, or do you not remember the other times you have disputed the problems with Virtualdub? There are countless numbers of posts here about Virtualdub's audiosync issues in capture. If it works flawlessly for you, that doesn't automatically mean that there are no problems with Virtualdub. All of my sync issues have been corrected with Amrectv instantly, with no other changes to my setup.

  10. One may also try VirtualVCR instead of VirtualDub. It's lean and solved dropped frames and AV sync issues which I experienced (years ago) with other capturing SW that time.
    It seems still to function under Windows 7/10.

    That's a frequent occurrence, but to say that VirtualDub is inherently flawed by design is not a logical conclusion when millions of users have no problems with it. I've captured literally thousands of hours of tapes for 15 years with VirtualDub, AIW cards and some USB cards, and with tbc iin the chain and never had audio sync problems on 5 different PC's over that time. Likely there are system anomalies in some OS setups that generate problems for some capture setups (including DV as well as analog). Agreed, a proper fix would be to use something that's more in agreement with whatever mushugana OS configuration is causing problems. I've seen where people had problems with Amarectv, too, but if that's what works in your system then obviously you should use it.

    Indeed there are -- but about 99% of those are lack of TBC at fault. Any capture software will have drops, because the software isn't at fault. You're making a misleading statement.

    If it works flawlessly for you,
    It does work flawlessly because I'm not feeding it a POS signal from a crummy old VCR, no TBC, and a cheap EZcap (Easycrap) card.

    Folks that follow my capture example/advice generally have a great experience, while those that don't generally find themselves in a circle of video hell. And that general advice is to capture lossless Huffyuv in VirtualDub, with recommended known-good hardware (VCR, TBC, capture card). It's not impossible to have a flawless experience.

    But it also requires NOT having knee-jerk reactions to issues with known-good software/hardware. (aka "Eww, VirtualDub sux, it gave me sound sync problems!") In almost all cases, conflicts are the root problem, devices/software won't play nice.

    All of my sync issues have been corrected with Amrectv instantly, with no other changes to my setup
    I highly doubt that was the only variable at play, if that is the case. VirtualDub is not necessarily the most dummy-friendly software, and sometimes settings do need to be tweaked. But video in general isn't dummy-friendly, there is a learning curve.

    All software has quirks, limitations, conflicts, etc (and that includes Amarec). Some more than others, and sometimes unusably so. But that's not VirtualDub.

    What's the model # of the VHS-DVD recorder combo?

    I don't have much experience with them, but the Funai-based model at Vancouver's library operates differently in normal VCR playback mode (no digital correction is done) compared to Dubbing mode (may solve your issue with blank tape sections, but with side effects):

  14. It's often possible to change the hdmi ouput resolution and other settings, so maybe you'll be able to get 480i from it (keep in mind that a TV will deinterlace a 480i signal). Granted, not all VHS/Burner combos (e.g many JVCs) can output video on all outputs.

  15. Back to AmarecTV . . . version 3.10 is available on the Japanese website (program is in both English or Japanese) and is, as far as I'm aware, the last version that doesn't force you to use their bespoke codec for capturing.
