How to Encoding supported in the BD standard pip video stream.

[24673583]

I want use MeGui encoding supported in the BD standard pip video stream.
how to do it ?
thanks!:thanks:

I don't really understand your question, but if you want to encode a Bluray compliant video stream, use the x264 bluray profiles included.

[Esurnir]

He's talking about Picture in Picture Blu-rays, Basicaly you watch the blu-ray and there is a mini video on the corner of the screen (used in wall-e bd for example, the short burn-e had a normal movie and one with the artworks in the corner while the movie played).

The h.264 encoder can't really do it. All I know about PIP is that they were High Profile Level 3.2 on the wall-e blu-ray And that it's probably the muxer/authoring software who can integrate them, the pip stream is "just" another pid video stream in the MPEG-2 Transport stream technicaly. I assume to make the blu-ray show that pip you must have metadata in the chapter files or in the stream itself.

You would need to use something along the lines of Sony Vegas to overlay the video.

On second thoughts avisynth can do this as well.

You would need to use an blu-ray authoring program if you want to have the option of displaying this overlay or not.
I don't know of any off hand.

The OP doesn't want to overlay video before encoding in an NLE / AviSynth, he wants to encode a separate stream which can be used as a PIP stream in a BD authoring app (I presume).

I've never done BluRay authoring, so I don't know what such applications expect for PIP streams, but it sounds like anything that's typically BluRay (but limited to 3.2 profile) would work.

x264 can certainly handle creating the stream itself. You just need specifics on what the BluRay spec supports for PIP streams.

Oh, and a $xx,000 authoring program ;)

Hi,Thank you all very much...
I am sorry, My english is not good!
I want use MeGui encoding a new 264 Video stream and supported in the BD standard pip video stream,from 1920*1080 to 720*480.
But i don`t know,How to do in order to meet the standard Blu-ray.

[Sagittaire]

- you must use the same framerate than primary stream
- Max level must be 3.2
- max bitrate for 720*480 must be 8 000 bps
- max buffer for 720*480 must be 12 000 bits
- sample ratio must be 10:11 or 40:30
- Total max bitrate for primary and secondary video stream must be less than 40 000 bps

Thanks!
A very big help!

Thanks to tips,
I have successfully encoding standards a PIP stream and supported in the BD standard.
Now,I want use MeGui encoding a main video stream(1920*1080p/.264),how to do it ?
For example,How much max buffer? How much max bitrate?
... ....
I hope,I will be the result of more detailed...
thanks!

I hope you mean kbps and kbits, else stream would look really terrible.

why?

x264 doesn't use slices. At least not in up-to-date versions (it used to do so long ago).

Unfortunately the BD specifications say that slices must be used. Hence BD authoring software that checks strictly against the specs will reject streams encoded by x264.

However, as far as I know, most (all?) BD players out there would play such streams without problems...
