"final video still contains all effects as intended in both cases?"<br>
<br>
Would it be possible to render a project with "traditional"
Cinelerra, then again with the optimized.<br>
Then import both rendered files into the traditional and set the top
track to "subtract".<br>
Shouldn't be it a pure black?<br>

Thanks for testing! It seems decoding/encoding (via ffmpeg embedded in
Cinelerra) already uses assembler optimizations, but effects still can be
accelerated via this 'cheap and dirty' technique.
BUT, most importantly, is final video still contains all effects as intended in
both cases? because there is no point in making fast but incorrect effects ...
