Major sequencer rewrite to add Speed Control effect.
Changes:
- Cleaned up large parts of sequence.c removing a lot of unnecessary code.
(We first built old seqar array to decide, what is visible, then build
dependencies with new code, then used old code to iterate through the
strips and deciding using new code what is used and so forth and so on...)
Should be much faster now.
- Now we build the strips recursively thereby elemenating the need of a
seperate dependency calculation.
- Added a Speed-Control effect to change strip speed afterwards.
(Offers global speed as well as IPO-controlled speed.
There are several modes to play with:
- Control by velocity (IPO = velocity where 1.0 is normal speed)
- Control by frame number (IPO = target frame)
- IPO-Value can be rescaled to frame-value, to make frame exact matching
possible. (Matching video tracks to audio tracks with IPOs ;-)
Demo-Blend file is here http://peter.schlaile.de/blender/sequencer/speedcontroltest.blend
Since this was also a Plumiferos request I hope to be mentioned in the
credits ;-)
Enjoy! And please test the new sequencer thoroughly. It is really more like
a rewrite this time.
