There's more Linux video editing news besides the new Cinelerra release
and the forthcoming alpha of Lightworks for Linux
. The latest open-source Linux video editing news is the release of Avidemux 2.6, which has seen its internals rewritten.
The BerliOS Avidemux page
for last week's 2.6 release mentions, "This one is a major rewrite of all the avidemux internals. It means that it will work better in most cases, but works worse in some. You can keep 2.5 and 2.6 installed at the same time, and it is probably a good idea."
So aside from seeing some improvements and possible regression as a result of this major rewrite, there's improvements to keep A/V sync, OpenGL filters, support for more scripting languages (SpiderMonkey, TinyPy, and Qt Script), support for hardware-acceleration via VDPAU, multiple audio tracks support, and everything is now treated as a plug-in (the Muxer, Demuxer, Filters, etc).
