Dear developers (...developers,developers,developers)!
Although I do not contribute to the cin3 source (so far ;-),
I have few thoughts:
1) Blender has great GUI and works with windows. If cin3 is working
on windows community is 100x bigger!
(Cin3 is called Lumiera)
Alas, I only think that this would help Blender users to adopt Lumiera,
as far as usability is concerned. I like Blender's powerful and flexible
tiled interface, but I remember when I tried to figure it out many years
ago. It was hard! I do NOT want to see Lumiera become more difficult to
figure out for newbies than Cinelerra already is.
Blenders also are programming, AFAIK, NLE as a module... ;-)
As far as I know, it's performance is slow compared to Cinelerra.
2) Since few month i use audio editor ardour2 - it has really
nice and quite stable multi-track interface. Maybe there is a chance
of reusing?
I don't know exactly what the developers' visions are in the audio
department. They'll probably leverage the jack transport to synch
Lumiera with Ardour and other audio applications. It's entirely
conceivable to patch the sound output via jack from Lumiera into
a DAW like Ardour, and even back again to Lumiera.
3) Cin3 must be fast and resposive with HDV. For example avidemux can
really fast play and scrub 1080i - many times faster than cin2.
Proxy on cin2 do the job but it is hassle to setup etc.
Should be "one button intermediate format mode".
MPEG2 seeking is quite sucky in Cinelerra. There is a lot of room for
improvement there, and promising work is being done on quick and frame-
accurate seeking. (not here, but on the libopenvideo mailing list)
4) cin2&HDV - what would you think about mixture of proxy and bgrender:
each source track is bgrendered to images instead of result. Then
with OpenGL composer most of ops could go smooth? My experience is that
[EMAIL PROTECTED] decode is a bottleneck.
On a modern dual core it shouldn't be, but in Cinelerra 2.x it is.
Richard Spindler has run some benchmarks on this, and if I recall
correctly, he could decode two HDV streams on a laptop and still have
CPU power to spare.
I hope you will not be angry with me for my "advices" ;-)))
Of course not. :-)
