Re-ran the test with lower buffer / bitrate limits:

What I can't understand is that Ben's file encodes and muxes fine, it's just this test file I'm using - but both are Lagarith. I thknk I need to sort out another test file and see what happens with that... |

Especially if the problem can be solved easily by using a better hosting platform. Thanks to "multimediaman" I'm downloading the clip from http://zshare.net/ in only two pieces and in a much more space-efficient format

as already, theres two clips there on skydrive.live.com that we all want to get and try at some point, there will be several more in time i hope too, thanks to benwaggoner etc, a generic rebol script might be very handy later. Last edited by popper; 26th August 2009 at 17:21. |

It's very kind of Benwaggoner to share his footage. But I really hope he will use a different hosting platform next time.
I know he likes to stick with MS solutions, but it's really pain, especially in this case

Ben actually tried many times to upload to the FTP account I set up, but the transfer kept failing because of a problem on this end. The SkyDrive solution is the one which worked properly, so take from that what you will.
Just so it doesn't get lost in amongst all this The Island trailer discussion, I'll ask again: Can anyone here share the secrets for encoding compliant Secondary Video streams? All I have so far is that the frame rate has to match the primary video, and since we're using AVC, the secondary video must be AVC also. And the max bit rate can't go above 8mbps, but this is talking heads stuff in SD resolution, so 2mbps should do it fine... Can anyone fill me in on the VBV buffer size? Number of B frames? Keyframe interval? |

DI only sets an upper bound for quality, not a lower bound . I could probably do a XScaler dithered version as well. |

The various post houses did their own segmented multithreaded mplementations (so an 8-core machine would simultaneously XScale the source in 8 chunks at once). |

Stacey Spears said that XScaler was "made available freely to just about anyone who wanted it" or something along those lines on the AVS Forum. I couldn't tell if this was in reference to studios only however.
It's a pity that the DPX sequence had banding as well. Perhaps they were a bit too aggressive in moving those bits around (12-bit linear should be the minimum DI IMO). EDIT: If there is one benefit to being a Microsoft employee, it's that you get to play around with sweet tools. Last edited by Biggiesized; 27th August 2009 at 07:29. |

I think the GOP length can be 2 seconds (minimum IDR is 1 frame). I think B frames are limited to 2 and reference frames to 4. BTW, Lyris I've been unable to register to comment on your website. What gives? Bad CAPTCHA script? |

Thanks for the suggestions, I'll try those out and see if I can get Secondary video to mux. |

Only restrtictions from default are: for SD (720x576 or 720x480) Level must be 3.2 vbv maxrate=8000 vbv buffersize=12000 (must be equal to level 3 because max DBP is 3037.5) max ref frames=6 for 720x480 and 5 for 720x576 for HD (720 or 1080) level 4.0 or 4.1 (slices are required for 4.1) vbv maxrate=40000 for Level 4.1, 24000 for level 4.0 vbv buffersize=30000 max ref frames=6 for 720 and 4 for 1080 other things are same as primary video (bframes=3, keyframe interval and etc..)

Thank you I will see if I can get this to mux successfully when I get home (just got back from a Sony SXRD projector event - the wonders of optics in masking compression artefacts never ceases to amaze me). The idea of secondary video is pretty exciting.
