Handbrake converted videos now 1/3 speed

[zelman]

Hello All,

Long time reader, first time writer. Thanks for the help in the past. Anyway...

I converted a bunch of files using Handbrake (CLI) to mp4's using the iPhone preset. A few of these videos are now playing back at 1/3 speed. What is the simplest (free) tool to change these videos to 300% speed?

Have you removed the source files? Or else try reconvert those with a different converter like ipodme.

I, unfortunately, did not save the source files. Any other thoughts?

[Baldrick]

It might be enough to adjust the mp4 headers but we need more information. What is the framerate in the files and the runtime? Identify using mediainfo.

And I guess you have tried play the files with diffferent players like VLC too see how it works.

I tried using MPlayer, windows media player, and my Xbox. All played super slow. Here is the mediainfo output:

It looks like the video header and the text header have the correct length, but the others are off. Any idea how to make them all agree?
