Hello.

First, thanks for your input!
Some comments: the design looks ok for me but the big problem is that you 
can't really just let people change a codec or a bitrate because there are 
many incompatibilities. I don't understand all ffmpeg parameters but I did a 
lot of trial & error to find some usable profiles for Kdenlive. My experience 
showed that you can't just let user change bitrate or any other parameter 
freely, because it simply won't work. If you set the bitrate too low or too 
high for your image size, it will fail. Some codecs (quicktime for example) 
only accept frame size if it can be divided by 16... Also, you can't mix some 
audio codecs with some video codex...

It seems to me that it would almost require a database to calculate which 
codecs are compatible, which size, which bitrate can be set for each size, 
etc.

If someone has an idea how to solve the issue, I am listening because that is 
too much for me.

Well I don't really care... the "create image clip" menu entry still allows 
you set the clip duration without having to open the clip properties 
afterwards, but you think it is cleaner to remove it I can do it...
