my openshot version is 1.4.3+0+735+66+278~precise1
on ubuntu 12.04.1
 with 0.8.2-0ubuntu0~sunab~precise1 version of melt

openshot update by ppa

during MTS video import in begining there is a warning from openshot on one sequence.

The file /home/jpp/Bureau/video a faire/00012.MTS has properties that may prevent it working properly in OpenShot.
You may need to transcode it to another format.

 If I delete only this file then export to file is ok.

It's strange because, this file comme from the same device ... so same format !

That warning means that the file is not seekable, so any cuts that are made won't work properly for example.

If you follow the instructions here - https://answers.launchpad.net/openshot/+faq/983 then you will most likely see problems when playing/seeking with that file.

But it's not a problem we can fix in OpenShot, as the file support comes from FFMpeg & MLT.

Hi, Openshot doesn't like my file 00012.MTS,
so I try with my file 00012.MTS melt, ffplay without problem

I will send you a debug from melt with a file 00011.MTS file that generates no problem with openshot
and a other debug with file 00012.MTS that generates problems with openshot

[jpp (jp-proux)]

I delete 00012.MTS from projet, and export is done without problem !

[jpp (jp-proux)]

How to regenerate h264 file to be clean for openshot before import them ?

[Olivier Girard (eolinwen)]

A conversion done, by sample with EnKodeur-Mixeur in DNxHD should resolve this issue, to my mind.
