Hi Bart, Can you post a small fragment of this file somewhere? -Yves On Wed, Nov 12, 2008 at 12:50:22PM +0100, bart.delva at labolamot.be wrote:

Hi,

I am trying to find a way to use my AVCHD shot footage (with a Panasonic SD9)in 1920x1080 25p on a Avid editing system.

Therefor I would like to encode these mts files to DNxHD 185 Mbit QT wrapped.

The ffmpeg transcode seems to run fine. I can fast import into the Avid bin... But the file plays stuttered ...

If I transcode the same source file using ffmpeg to a simple MPEG2 and play this back in VLC player, I get the same stuttered playback. So the problem must happen while decoding the mts file.

I use latest windows build (SVN 15666)

Here is what ffmpeg reports in debug mode:

ffmpeg -i 00000.mts -vcodec mpeg2video -b 20Mb -s 320x180 -qscale 1 -q min d:\output.m2v -debug 1

In Verbose mode I get a lot of these errors:

Any ideas if this is known ... Or how to solve it ?

Thanks.
