    I have found another way to cure frame drops even though it probably has been mentioned before.

    I recently bought a Canopus ADVC50 but had jerky video and sound drop outs.
    Canopus advised me to substitute another VCR in a process of elimination, and the problem was gone.
    Trouble is the VCR I use for capture is a new JVC with S video output which I bought particularly for this project.
    So I looked at the various functions in the JVC's set up. One of them was "video stabilizer".
    I went searching for such things because I had solved frame drops before by turning off auto tracking and controlling it manually.

    As soon as the "video stabilizer" was turned off the problems with the ADVC50 appeared to be gone (I am still testing).
    I went back to capturing full resolution avi in virtual dub (where I had been dropping frames) and there were no frames being dropped there either. During caputure I turned "video stabilizer" back on and presto: frames dropping all over the place.
    Turned "video stabilizer" off again and no frames dropped.
    In fact the caputure is now so stable I may not need the ADVC50!
    But it is nice knowing the audio is locked to the video, all I have to do now is work out how to edit the DV files made by the ADVC50 within Virtual dub.
    Any good ways to do this? I prefer not to use TMPGENC as I create 4000kbps MPG2 files and TMPGENC makes them look blocky,especially if there is fast movement in the video.

  2. From the downloadable user manual for my JVC HR-S9500U S-VHS VCR.

    "By activating the Video Stabilizer you can correct vertical
    vibrations in the picture when playing back unstable EP
    recordings that were made on another VCR. When this function
    is set to "ON", vertical vibration will be automatically corrected.
    *The default setting is "OFF".


    The Video Stabilizer is only for viewing poor quality EP recordings. You shouldn't have that setting turned on at any other time.
