CONVERTING MPEG 4 TO MOV FILE, ONLY FIRST 30 SEC OF CLIP WORK,help please !

[Haymaker]

Hi All I am going crazy here, I have been trying to get the compete file into fcp of for more hours that I would admit.
I have a MPEG 4 video file originally from a convergent NANO. I can play the whole clip 13.40 mins on VLC no problem, but as soon as I try to convert in Slipstream or qt7 or compressor none of them can see more than 30 seconds of the clip. So they convert 30 seconds of the clip and no more any suggestions very welcome the original file is about 3.7 gig of material shot on a SOny Ex1

is this from a nanoflash ? it uses mpeg2 not mpeg4 video (ex-1 used mpeg2 as well). Is it packaged in mxf or mp4 wrapper ?

try ffmpeg

ffmpeg -i video.mxf -vcodec copy -acodec copy output.mov

No google cannot find the downloads on this site, IF I do manage to get hold of it what do I do with it ? its a codec right ?

Hi there , is it mpeg2 in mp4 container ? like xdcam native footage ? you can use mediainfo mac to check

ffmpeg is a command line utility that is crossplatform, available on pc/max/linux . For this, all it's doing is re-packaging the contents into a .mov container, which is more compatible for mac platform , and fcp

Here are instructions for almost the same thing, but I'm not sure if the batch method will work on a mac:
