Hi, thank you for your report. If you can run Kazam with --debug option and paste the output here, I'll get more information on how to deal with this.

Well the problem now is that the preferences are not saved.
If I try to set WEBM format, Kazam records always in H264. If I set WEBM and I close and reopen Kazam, in the preferences there is always H264. So actually I can't test the WEBM recording until I can't set properly the preferences.

I'd like to see a debug log from your full session. So far there were no problems with preferences. You could also try to remove ~/.config/kazam/kazam.conf.

I have deleted the "kazam.conf" file, but the issue with the preferences is still present. No way to set what I want. Now the codec used is always RAW/AVI.
Anyway here the "kazam --debug" messages::

Thanks for the log. I apologize, because I wasn't clear enough, I wanted to see the log from when you start Kazam, open preferences, change codec and then start recording.

There's a reason why codec selection isn't remembered and it would be most helpful if you are able to catch an exception or any other kind of errors.

I see, but the problem is that even with the command "kazam --debug" I can't capture any issue with the preferences.
I have changed the recording format from RAW/AVI to WEBM, but nothing is written in the terminal. As you can see here in my debug session, the format displayed is always RAW/AVI.

Is this still present in the latest version of Kazam? 1.3.101? If yes, please attach one more debug log.

Well, kazam now works with the webm format, but the video output is far from perfect.

1) The audio and the video streams are not always very well synchronized.

2) When I try to open the video with Totem, I have this error:

Thanks for all the input. There are some know issues with WebM and I am still looking into this. It appears to be a bug with GStreamer backend and VP8 implementation. As a workaround, please use H264 for encoding videos.

wrong result webm file Edit (1.0 MiB, video/webm)

Hi,

I'm using kazam 1.4.3 on Kubuntu 12.10. Recording with webm didn't give any error, but in the result webm file only maybe 5 pixel in the middle was shown. All other parts in the left and right were black.

Please see the attached 3.webm. I recorded a window but the result was like that.

Is it also because of the gstreamer backend problem? Any suggestion to avoid this problem?

If there are still issues with this bug in Ubuntu 14.04 and Kazam 1.4.4, please run kazam with --debug option again and attach the output. Thanks.
