    TVs just plain don't care - they don't need to know where a frame begins or ends, they just display whatever bits come in.

    The digitization process, however, is far more strict. It needs to know where a frame begins and ends. Timing is critical because the frame begin/end cues are in the video.

    You can think of it like listening to someone who speaks with an odd cadence and pauses in the middle of sentences, not at natural breaks.

    For example, if you called me and asked what I need from the grocery store and I responded with "I just need milk ----- and eggs ----- not white ------ sugar."

    It would be confusing. You might hang up on me before I finished my list.

    Or you might misunderstand me and think I needed brown eggs, instead of brown sugar.

    What is the video capture card that you are plugging the RCA composite yellow cord into?

    But then why, when I plug it into my HDTV, is it ok...with no jumpy picture? Does an HDTV correct for things like tbc?

    Like Anton said the 110 doesn't have the TBC in it bit the 300 does. That is part of the price difference.

    the advc110 does not have a TBC, it converts analog to digital, if the analog jumps, the digital jumps

    a TBC removes jumps by inserting a new timebase, therefore producing a stable signal as if it would come out of the head of a camera

    started a topic hi8 transfer to hd "jumpy"

    hi8 transfer to hd "jumpy"

    done with vhs transfer to hd...moving onto hi8 and having some problems.

    i'm using an old sony handcam ccd-trv36 to playback my old hi8 tapes and transfer them to the hard drive. the problem is: the playback is bad. the lcd screen and the realtime screen in edius neo shows a "jumpy" picture, an inconsistent representation of the recording. i plugged it into my hi-def tv and it worked fine, surprisingly.

    when i capture, i shut down all other processes and don't do anything on the computer. there is no firewire output on the camcorder, only a yellow rca cable for video and a black one for audio, which i used a converter to get a stereo sound.

    im not sure what the problem is. can't be "dirty" camcorder heads because it worked fine on the hdtv. can't be the firewire cord or the computer as they're both new. i'm also capturing to an os free spare hard-drive. i'm really at a loss here.

    thank you.
Working...
