Blu Ray- MPEG2 or h.264???

[Angelo Lorenzo]

All standard Blu-Ray players have to support mpeg2, h.264/AVC and VC-1 as video codecs. You're not out in the rain with either in you choose to go with mpeg2 because it's faster on your system. h.264 is usually the choice since it allows more content on the disc. Looking at manufacturing stats http://www.blu-raystats.com/Stats/St...leaseDate=2012 (summary at the bottom) it looks as though the vast majority of commercial blu-rays are now using h.264/AVC exclusively.

I'm definitely seeing that it's an h264 world. Anyone use one of the cool accelerators from Matrox?

Hi,

AVC-1 or H.264 is more efficient but takes much longer to encode...

--> High quality final Bluray: use two pass HQ H.264 codec
--> Daily footage preview 4x realtime encoding: use MPEG-2 single pass with maximum bitrate

MPEG-2 old technology?

We use high bitrate MPEG-2 footage (80 MBit/s) a lot for professional harddisk players - it's much faster to encode and is absolutely artefact free... so it's the better format if you have tight deadlines...

Yes, as documented MPEG2 is "Old", but as Danko shows, not necessarily out dated. Either MPEG2 or h264 can provide visually perfect imagery. The variables listed are encoding time for you, storage space for you (DVD/bluray or web server), transfer time for your viewers (web), or decoding power for your viewers (computer power/graphics acceleration). Usually I deliver MPEG2 on DVD and h264 for Bluray or web.

Cool. I'll bump again and ask if anyone out there has used the Matrox accelerators?

Hey Paul... I've been using the CompressHD for quite a while now. I'm even selling it at the moment (http://www.reduser.net/forum/showthr...4-Encoder-Card)! Only due to the fact that I've purchased an MXO2 LE Max, which does the same thing...

To your question... it basically cut my encode times for H.264 files in half, even from 4K source. Doesn't mean it will necessarily cut everyone's render speed in half, because obviously everyone's computer setup is different... but my tests should be a good indicator that it will greatly speed up your renders. You can see some of my render speed test results from this thread: http://www.reduser.net/forum/showthr...287#post940287

If you have any specific questions, let me know and I'll do my best to answer them!
