I am experiencing corruption nearly always when seeking in my Full HD clips that are recorded on my Sony HDR-CX105 (europe's version of CX100)

I have created a camera profile and uploaded some sample MTS footage in the hope that someone can take a look

I have tried dropping B frames in the prefs but to no avail.

I'm the maintainer of an open source project called Asterisk Desktop Manager, and I know how much work is involved in maintaining a project like this, so I'd just like to thank everyone who has contributed to this project and compliment them on their excellent work.

I am trying to attach an image of the corruption in the clip monitor but i get this error



The selected file Screenshot-Untitled - HDV 1080 50i [modified] - Kdenlive.png could not be uploaded. The file is 221.6 KB which would exceed your disk quota of 1 MB.

It is clearly under 1MB

I see the same thing with my Canon HFS100, which also puts out AVCHD .MTS files.
As a workaround I use this script, which you run in the directory containing the MTS files. It converts the MTS files to mpeg4 files of the same quality and those work fine in kdenlive. You can run it twice in the same folder and it will only convert the files its not converted before.

Like you I suspect this is not a kdenlive problem.

#!/bin/bash
for infile in *.MTS
do
outfile=${infile%.MTS}.mov
if [ -a "$outfile" ] ; then
echo "Skipping already converted $infile"
else
echo "Converting $infile"
ffmpeg -i "$infile" -acodec pcm_s16le -ac 2 -vcodec mpeg4 -sameq "$outfile"
fi
done

Thanks, this is a good short term solution but it doubles/triples the time it takes to create a film.

Any update or any of the devs willing to look at the samples to help?

Thanks

I get corruption while seeking on HF100 clips. Renders of edited material are fine, it's just the editing part that sucks. Recoding is not a good solution for me as it takes forever, the files are huge, and the quality is degraded a bit. A workaround is to always go to the beginning of the clip with the Home keys or alt-left and alt-right arrows. Then hit play and the clip always plays fine. Basically, I just don't seek. It is pretty painful on longer clips since it may take you a long time to get to the part in question. But I tend to do short clips and I've kind of gotten used to doing this. Until this bug gets worked out I can deal.

You should probably take this problem to the ffmpeg guys from the sound of it.

The seeking to home and playing the clip through is a useful tip, as you say in smaller clips. Thanks
