Encoding '12bit - 4:4:4' YUV in MBAFF

[sabeelmk]

Hi

My question is related specifically with encoding a YUV in MBAFF.

I would like to know if "x264" encoder do the following

1. Can 'x264' Encode '12 Bit YUV,with 4:4:4 chromaformat' in MBAFF ?

2. Can 'x264' take raw YUV file directly as input,for encoding ?

I have tried JM17 encoder for the above requirement,and JM17 encoder has a bug in encoding in 12bit Yuv,with 4:4:4 chroma format in MBAFF mode (with Separate colour plane = 0 and 1 )

Is there any other encoder that do the above?

Thanks

1. I don't think so. If you need to encode it to bluray or 8bit 4:2:0, it's better to dither down your source (a step that you need anyway to do)
2. Yes, in YUV4MPEG (Y4M) file format.

appreciate ur response

But my requirement is strictly encoding the following

1. 12 Bit Yuv,of 4:4:4 chroma Format In MBAFF

additionally,The purpose of such a stream is for next generation products.

thanks

x264 supports only 4:2:0 colorspace (YV12).

To encode in such specs, you need an Hi444PP profile encoder. I don't know actually any encoder capable of this (maybe some hardware-based encoder?).

High bit depth support is a summer of code project, so you can probably expect to see it very soon. As for 4:4:4 I don't believe x264 currently supports it. You could, of course ask on IRC and see if anyone is willing to write this.

Hi

Can u please elaborate what is "IRC" , where can i find it...

information of any other encoder that can do what the thread is about,is welcome

You can put a look at Cineform.

I don't know actually any encoder capable of this (maybe some hardware-based encoder?).Mainconcept support 4:4:4 up to 14bits and MBAFF

[mp3dom]

Really? Are you referring to 'Reference' or SDK?

[shon3i]

Really? Are you referring to 'Reference' or SDK?
reference can only do a 10bit, sdk can go to 14bit, both can use 4:4:4

[sabeelmk]

Hmm

Interesting

Shon3i,i think i have to check out the SDK of Mainconcept,and see wether the code does 12bit 4:4:4 encoding,only issue is i hope,the executable from the mainconcept sdk can take YUV input for encoding...

[shon3i]

only issue is i hope,the executable from the mainconcept sdk can take YUV input for encoding... If not, you can use DirectShow Filter instead.

[sabeelmk]

If not, you can use DirectShow Filter instead.

shon3i,u mean using something like a graphedit to do that?

[shon3i]

yep, or graphstudio.

[sabeelmk]

yep, or graphstudio.

Cool..but i am not sure we can plugin a Mainconcept SDK executable in graphedit..i am assuming that the sdk output would be just a normal executable(.exe)

[shon3i]

no you can't use executable only direct show filter through graphedit/studio.SDK usualy came as directshow filter, but executable is also available

[sabeelmk]

@shon3i and All

Guys
i checked the mainconcept sdk site,i found out that mainconcept sdk doesnt support 12bit, i dont think i found anywhere on that site that mainconcept sdk has support for 444 and 12 bit

i dont know if it is right to post links,but for reference here is the link giving description of mainconcept sdk
http://www.mainconcept.com/products/sdks/video/h264avc.html

looks like only JM 17 encoder does MBAFF encoding of 12bit,444 yuvs,but with bugs :-) ..

[shon3i]

i dont think i found anywhere on that site that mainconcept sdk has support for 444 and 12 bitTrue, but one thing is for sure 444 is supported. You can download their Reference 2 software and you will see High 444 profile, but only up to 10bit. Anyway their SDK can go up to 14-bits, at least version i get.
