FFMPEG: from .mxf to mjpeg encoding

[marcorocchini]

Hi anyone,

I would like to encode from .mxf (sony xdcam hd 422 files) to mjpeg 422

I have to upload my C0020.mxf file to my dropbox:

Initially I used FFMBC:

FFMBC -i C0020.mxf -vcodec mjpeg -an output.avi

but it returns this error message:

Incompatible pixel format 'yuv422p' for codec 'mjpeg', auto-selecting format 'yuvj420p'


but I don't want a 4:2:0 file


So I have try with the zeranoe version of FFMPEG:

FFMPEG -i c0020.mxf -vcodec mjpeg -q:v 0 -an output.avi


it produce a mjpeg file but my NLE is not able to read the output.avi

This is the report of mediainfo:

Maybe is unreadable because it is not (clearly) an interlaced output?

I would like to encode an interlaced mjpeg file, how is the setting of the FFMPEG to encode in interlace mode?

thanks!

looks like ffmpeg thinks the source is progresive - notice the "p" in Incompatible pixel format 'yuv422p'

can't help with fixing it though, never worked with interlaced mxf.

the "p" in yuv422p indicates "planar"


marcorocchini - this was suggested to you many times, but you should just upgrade your NLE. XDCAM-HD is one of the most popular, commonly used formats (esp. in broadcast)

I don't think there is any interlaced encoding for mjpeg

in ffmpeg, generic interlaced switch is usually -flags +ilme+ildct , and -tff for top field first, or -bff for bottom field first. Some builds use -top 0 (bff), or top 1 (tff)

oye. anyway downloaded your source and it works fine in vegas pro 12. not sure what you want to do with it?

because i would like use my modifyed In Sync Speed Razor 5.51 NLE

poison, a kindness:

I have partially solved in this way

ffmpeg.exe -y -i c0020.mxf -vcodec mjpeg -vf crop=1920:1080:0:0,colormatrix=bt709:bt601 -pix_fmt yuvj422p -intra -q:v 0 -an output4.avi

but now I have a problem with video levels:

in FFMPEG is possible to change from 16-235/16-255/0-255 levels?

thank you

I frist thought that:

-color_primaries   <int>        ED.V.. (from 1 to 8)
  -color_trc         <int>        ED.V.. (from 1 to 7)
  -colorspace        <int>        ED.V.. (from 1 to 8)
  -color_range       <int>        ED.V.. (from 0 to 2)

might help, but reading http://trac.ffmpeg.org/ticket/443 it seems not the case, so there is probably no way to convert between tv and pc scale or tell ffmpeg that your input is either.
As far as I know for RGB content ffmpeg assumes pc and for all yuv content tv scale,..

[poisondeathray]

mjpeg is frequently decoded as full range yuv - it's also dependent on the decoder settings in your application. Some mjpeg decoders will clamp to 16-235. "yuvj422p" will be full range YUV. (The "j" indicates full range 0-255), so if you decoder doesn't clamp, it will be 0-255

I see there is a new curves filter in the ffmpeg 2.0 changelog. If it works like typical curves filters, you should be able to change levels

[Selur]

looking at the different pix_fmts:

4:2:0, 0-255

-pix_fmt yuvj420p

4:2:0, 16-235

-pix_fmt yuv420p

4:2:2, 0-255

-pix_fmt yuvj422p

4:2:2, 16-235

-pix_fmt yuvj422p

4:4:4

-pix_fmt yuv444p

wouldn't ffmpeg do the conversion automatically if set the input and output pix_fmts to different values?

-> okay, forget that, seems like one can only set the pix_fmt for the output,...

[aedipuss]

i can't find a way to force 422 out of ffmpeg. you could use the utvideo lossless codec. it has a 422 rec709 component.

[Selur]

"-pix_fmt yuv422p" should force 4:2:2 output,...
