[Kdenlive-devel] critique of 0.7.2.1

Sun Feb 15 14:35:35 UTC 2009

This seems like a great questionare for the FAQ.
To summarize, the feature requests are:
- zoom be y axis (height)
- hard grouping of clips (lock clips, not just to be able to select them as
a group you can now)
- cache + proxy support
- keyframe framework for automation of effects/events

You also seem to have a OS related problem, i can playback raw m2t @
1920x1080 25p without problems even with effects, and it seems to affect
your rendering too.

Enjoy,
Slavko

Brightness can be edited by adding the brightness plugin (and you get a nice
line on the video clip itself to manipulate)
