Hi there,
Just wanted to hear people's opinion on this matter - I'm currently working on a video with Vegas Pro 12 that's been shot using multiple (different) video cameras, all the tracks have been synced and are now color corrected & matched together using PluralEyes 3. The only problem is that - for the sake of the workflow - I try to minimize the playback slugginess and have been developing different kind of approaches on my desktop edit unit throughout the past years.
The problem is that it's hard to decide whether I should render the actual "final" work cuts from each camera as Sony MXF or render them using MainConcept/Sony MP4 codec with steady 50MBps stream rate.
I have a decent GPU card with OpenCL support (AMD FirePro v7900) in my edit station (Intel i7 core-860 + 16GB RAM). Tthe render times are way faster when using GPU-accelerated MainConcept MP4 templates @50MBps constant bitrate than what they are when I'm rendering to Sony MXF files.
Whenever rendering to MXF, my video card isn't utilized _at all_ (checked it out with a program named GPU-Z that's freeware and very handy for monitoring GPU load & usage). With MainConcept MP4 rendouts the rendering goes much more faster and my GPU is actually utilized.
As far as I know, in this case the render time is caused by Sony's plug-ins that I'm using (ie. color correction) that are GPU accelerated when rendering - but only when using certain codecs. MXF it seems is not one of them. There is no GPU usage whatsoever.
However, when MXF rendering, the algorithm actually checks whether or not recompression is required. If not, the render times are lightning fast (about as fast as your HDD/SDD I/O transfer rates).
So - as for me, after rendering the files to as-high-as-possible video formats per each video track, the next step is to start editing the project in multi-track video mode. I'd like to hear your opinion on editing multi-camera HD-video.
Should I render the master duplicate (ie. originals) using Sony/MainConcept (MP4) or stick with MXF? Benefits vs. drawbacks on each one? What about video proxies? Now that the material has been color matched for each camera track, should I make a video proxy rend for each vid track as well in order to avoid sluggish playback?
Thanks a lot for your help, opinions or comments in general regarding this issue.
