I've been using Kdenlive for a while and I think there a few features missing (at least I'd like to have :-)) :
- a easy to use crossfade transition (video + audio) : for instance you just have to overlap two clips and it's done ! (I know I am not the only one to ask for it...), like OpenMovieEditor does (if you need an example)
- when resizing clips it would be nice that preview automatically shows the action you're doing (so it is easy to adjust where you want to cut your clip). at the moment the preview is stuck to whereever the "read cursor" is.
KDE4 version is a very nice version. much more usable according to me that any previous version (I have very few crashes, playing with clips is much faster, etc...).
And please implement the thumbnail cache because it takes about 20 minutes for me before I can use properly the software, because it's loading my thumbnails (yes I have a lot of clips...).
Regards and congratulation for the 0.7 version, as every software for KDE4 it is the begining of a great experience !
