Does Method of .mp4 production affect buffering? Created Mar 18, 2010

Here's a strange quirk that I seem to have uncovered:

If I take some older videos that I created mp4 files out of using the freeware Any Video Converter and but them in Flowplayer, they will play, but they won't buffer correctly - the entire movie will download before the movie starts, regardless of the bufferLength setting.

If I convert using Handbrake from my camera's native .mov format, the autoBuffering, bufferLength works perfectly - it will buffer a portion of the video, and then begin playing.

Here's a couple of examples:

Will Buffer correctly:

Has anyone else experience this quirk?

Is it possible that some video editing somehow loses the markers that enable flowplayer to determine the running time of the video downloaded? That seems odd, but I'm not coming up with a better explanation.
