  1. I'm capturing VHS tapes using ADVC300 as Type 1 DV files. Type 1 DV files seems to fix audio video sync issues known to ADVC300.

    MPCHC reports the files as Unknown [Stream 00]. Is this normal? The files play fine but AVISOURCE will not detect the audio. Maybe AVISOURCE will not work with Type 1 DV files. DIRECTSHOWSOURCE can create audio video sync issues if there are video hiccups. FFVIDEOSOURCE seems to be unable to or takes forever in opening large DV files (30+GB) even when I've made the index available using ffmsindex.exe.

    Code:

    I have to use VirtualDub and do direct stream copy for MPCHC to report the steams correctly and AVISOURCE to detect the audio. According to GSpot, VirtualDub export the files as Type 2 DV files.

    Code:
    General
    Format                         : AVI
    Format/Info                    : Audio Video Interleave

    Re: MPC-HC, dunno, can't check my other computer for DV files at the moment.

    The incompatibility with Type-1 audio is noted in the AviSource documentation.

    Maybe load video with AviSource and audio of AVI with FFAudio or other.

    you could just change from type 1 to type 2 - https://www.videohelp.com/software/DV-Type-1-to-DV-Type-2-Converter

  4. In case you're not aware:

    The DV data stream from the camcorder (or capture device) arrives at the computer with video and audio already multiplexed. When stored as a Type 1 DV AVI file the data is stored in a single stream in the AVI file -- marked as a video stream (even though it also contains audio). When stored as a Type 2 DV AVI, the audio is copied and stored as an additional stream -- an audio stream. So Type 1 files have only one stream marked as video, and Type 2 has two streams, one video and one audio.

    Long ago, when computers were much slower, Type 1 made sense since it required less work while capturing. But since the audio is in the video stream software has be written specifically to handle the audio. AviSynth's AviSource() does not know how to access the audio from the video stream. It only gets the video. Many other programs have the same problem.
