When I trim the end off of a video from my Flip video camera using Avidemux 2.5 I often get a white blank screen at the end of the video. I think the video format of the Flip video camera is H.264 (MPEG-4 AVC).

I use the video copy audio copy mp4 settings. It does not seem to help one way or another to say yes or no to the popup that says do you want to do something with J frames when I load a video.

Thanks!
