Hi there,
I was doing some rendering tests here, especifically trying to render to
JPEG Photo (MOV) format or TIF Sequences. I noticed that Cinelerra is
using very few of the processor capacity. For other stuff (such as
compiling), I noticed that using an option (for example -j +0) would
improve processing quite a lot, using all the cores of the processor.
So, is there any way that I could activate multi-thread processing for
any of these two formats?
cheers,
flavio
TIFF is usually uncompressed and JPEG is weakly compressed. This means, that
disk I/O becomes the bottleneck and the system spends most of it's time
waiting for the hardware. I would guess that multiprocessing won't help
here. If you do some CPU intensive operations however (like filtering),
the situation changes. Multiprocessing *can* help here if supported by
the software. No idea what cinelerra can parallelize here.
