Weird mp4 problem

[ro2124]

I am trying to edit a mp4 file using avidemux but when it loads , just a black screen and none of the edit functions do anything.

When I right clicked file and looked at details under properties everything, like bitrate, frame rate,etc was totally blank

Strange thing is though the file plays ok in video players.

Never come across this before any ideas?

Probably a proprietory format.

ISOM immediately springs to mind. But what does mediainfo (text mode) say, if anything, about it ?

[ro2124]

Tried Media info and yes there all the info is displayed.
Also at the moment recoding it with XMedia which seems to work although taking ages. After that maybe can edit with Avidemux we will see.
oh yeah and whats ISOM?

[DB83]

A little more help could be forthcoming if you shared the mediainfo report.

AFAIK ISOM is a M$ proprietory format

So did that recode work ?

One other possibility is that the video had DRM attached. Then editing/copying is nah impossible.

Upload the file so people can analyze it.

[ro2124]

well actually managed to solve it the way I said before, recoded with XMedia which took bloody ages, but after that avidemux worked and job is done -so happy endings

And no one is any the wiser what was in the original that caused the problem.

True, but deleted original file now so cant share details,
anyway still may be of help to others who may have similar problems that it can be solved by recoding with XMedia, but point taken should have listed details befpre so ok I stand in the corner with Dunces cap for 5 minutes as punishment OK?
