Re: MXO2 mini MPEG2 Acceleration... by Andy Mees on May 22, 2009 at 9:05:53 am
Hi Peter
The MXO2 mini is designed as an I/O device, thats I for Input and O for output ... it facilitates getting your audio/video content into your editing system, critical evaluation monitoring of that content during your edit, and outputting the final edited footage (for example, outputting back to tape, or to a DVD Recorder etc). There will shortly be a second version of the Matrox MXO2 mini released which will include the Matrox MAX technology, and that later version will allow for faster than realtime encoding to the H.264 format .... but not to MPEG2.
So, will the MXO2 mini accelerate the rendering of MPEG2 to realtime? No it won't, but it will accelerate rendering of H.264 to faster than realtime.
Does it helps to edit MPEG2 for playback on the machines that cannot do? It may help you to capture the source footage to a more edit friendly format perhaps, at which point your edit system might be better able to handle it.

Hi Peter,
I have found that with a fast PC, MPEG-2 encoding is already faster than realtime, so really no need for an accelerator. My Quad-core workstation will encode NTSC to DVD much faster than realtime, and for HDV 1080i to Blu-ray, nearly realtime.
Being a much more complex codec, H.264 takes forever to render and that's where the hardware acceleration comes in handy and the CompressHD card or MXO2 Mini w/Max will quickly pay for themselves.

Well Ravi, my guess is that unless or until supporting functionality is built into both the host NLE's and the MAX drivers then it wont help direct editing of AVCHD at all.
