[Soc-2013-dev] Weekly Report #4 VSE

[David Jeske]

Below are some comments which I believe are in-line with Ton's directions
and may be helpful... These are from a thread I created on BA to try and
help create concrete proposals and mockups for the VSE.

One interesting (I think) suggestion from the thread is to extend Blender's
TAB/edit-mode metaphor to
VSE<http://www.blenderartists.org/forum/showthread.php?299319-Help-redesign-the-Blender-Video-Sequence-Editor!&p=2422179&viewfull=1#post2422179>.
By selecting a single-strip and hitting TAB to enter edit mode on that
strip, the rest of the VSE strips would become frozen and that single clip
could be viewed/scrubbed in the preview region, slipped, in/out edited,
split. This seems like it would fit well with blender's existing
object/edit mode metaphor.

I'm fond of a suggestion to make lightweight left-hand-side headers which
allow collapse/expand per channel (somewhat like in graph-editor,
dope-sheet, etc).. when collapsed a channel could possibly be even
vertically shorter than it is now, and when expanded they would be taller
to accommodate visuals (audio-waveform, preview images, etc) The current
model is to toggle audio-waveform-visuals per-clip, which is both extra
work to toggle it for several clips, and requires the clips remain the same
vertical height always.

Other strip suggestions are:
- linked audio & video clips which stay together
- snapping<http://www.blenderartists.org/forum/showthread.php?299319-Help-redesign-the-Blender-Video-Sequence-Editor!&p=2420907&viewfull=1#post2420907>(mirror
3dview, snap-to-strip-endpoints/markers, shift-tab enable toggle)
- ability to view/edit a single animated attribute directly on an expanded
strip. (for example, volume level)
- mute/unmute channel (standard "eye" on the left-header)

- Make threaded prefetch work again

Not sure if this is related or not, but turning on audio-waveform-visuals
for a clip also stalls the UI while it's generated. Definitely will need to
be fixed to add more visuals (and images)

Yes!
