  • Marvel Skipping Frames...Solved For Me

    I had to title this as SOLVED FOR ME because of course, there are no guarantees.

    I had the same problem as was being discussed in the "Marvel Skipping Frames" topic. I would get 0 dropped frames in capture, and anywhere from a few to a lot of jitters in the AVI playback. In fact I just finished a project, made 25 copies out to videotape, and noticed every once in a while the output would jitter. The thing is, it jittered in different places each run.

    I read this forum and figured I'd do some experimenting. I disabled VIRTUAL MEMORY and rebooted. The AVI Jitter problem went away. Played the same AVI that jittered every time during my recordings and played through smooth. In fact, played it back 3 times. Not one jitter. Then, I re-enabled virtual memory, rebooted, played back the AVI file, and bingo...jitter.

    My system is a Celeron 300, 64MB RAM, 2 hard drives. A 5400 RPM system drive and a 7200 RPM Video Drive.

    Can't guarantee that disabling the virtual memory will work for you, but it did the trick for me.

    WOW. I'm going to try this tonight. I have a similar system and I have to watch every tape I output to check for jitter. I usually get 1 good video (no jitter or minor jitter) out of 5 attempted outputs.

    Thanks for the TIP.

      Disabling virtual memory in a system under 128 megs is a risky business. This could easily cause a crash when editing a longer project.

      A better way would be to limit the VM swapfile to fixed size of 128 megs, disable write behind cacheing on all drives and get CACHEMAN off a D/L site so as to get the VCACHE under control. From within CACHEMAN set the VCACHE min and max cache sizes to no more than 8 megs.
