Xuggle Error:
Xuggle has encountered the following error while opening this video:
"moov atom not found"

And tracker says: Cannot open the video.

There ist no problem with the video but it is about 2,75GB big. This problem occures with other big videos, too.

Is there any possibility to help or do I have to cut every video bigger than a particular size?

Thanks for your help

Hi Martin,

Have you tried switching to the QuickTime video engine to see if it will open the video? To switch, select QuickTime in the video tab of the preferences dialog (Edit|Preferences menu).

If that doesn't work, I think you will indeed have to split the large videos into smaller files.

Hope this helps.  Doug

Hi Doug,
thanks for your fast answer!
Yes, I tried the same video on another computer and this one had the quicktime video engine. Then it was working =)
Kind regards
