Dear all,

I sometimes have to make screencasts for lectures for my students. I've tested many different packages and so far Kazam seems to work the best. (Now I am also trying to follow these instructions: http://ubuntuforums.org/showthread.php?t=1392026, which seems to be a good idea.)

My problem is that it saves to MP4. The video editor I've more used to is avidemux (from the infamous French repository, so the "Dragons..." sub-forum), but it has problems with the encoder (h.264): first, when opening the file, I get:

      Code:

H.264 detected

If the file is using B-frames as reference it can lead to a crash or stuttering.
Avidemux can use another mode which is safe but YOU WILL LOSE FRAME ACCURACY.
Do you want to use that mode?


But then, whether I chose Yes or No, most of the time I get the error:

      Code:

KeyFrame error

The beginning frame is not a key frame.
Please move the A marker.


All I need is cutting and merging files (pasting/inserting a new file), nothing fancy. I've tried a few different editors (like Lives, KDEnlive, pitivi...), but they either have a problem importing the file or I could not figure out how to accurately cut and insert files. Any suggestion would be greatly appreciated.

Best to all,

Luis

I've no video editing experience as yet, but I just read this:

http://libregraphicsworld.org/blog/entr ... deo-editor

(Idea That website is chock full of awesome Smile)

The Getting Started video tutorial prompted me to install it to try it out, as it looks very simple to use yet powerful. Like Ardour (an awesome DAW) it uses self-contained packages instead of Debian packages, which make upgrading non-automatic (and non-Debian-way) but do allow use of cutting (/bleeding?) edge versions and libs which may not yet be in distros.
