I am just wondering if there are any ways I can change "tic" of jog function (you know, in MacShapa, you could adjust it). I don't really understand how Openshapa adjust the tic for jogging. I was using the ffmpeg to create quicktime movie, but now, I am using final cut pro to convert AVCHD file to quicktime movie. And I noticed the Openshapa doesn't jog consistently, sometime the tic is whipping 1 second depending on how I convert the movie, and I just cannot figure out how OpenShapa handles the jog.

Hi Ken,

We have similar issues with jogging based on the video format. The solution at this time is to try opening the video using the gstreamer plugin. This QA post details how to do that: gstreamer plugin

Thanks John. I installed the gstreamer, but I never used it!

I really like coding the video frame-by-frame (I recorded the experiment with 30P), but I believe OpenShapa jogs 40 milliseconds per jog (25 tics per seconds) which is far less than actual frame rate of video. I guess I could encode the video with 25/24 frame per sec...

Thanks again!

I'm having similar issues and I'm not exactly sure why. The regular plugin will jog at the frame rate of your video if it can read the frame rate, but sometimes the video's time code is hard to read. Maybe Clinton or Jesse has a better fix for this.
