ProRes 422 & ProRes 4444

[Tommato]

Hi,

is it possible with GStreamer to save a mov file in ProRes 422 and ProRes
4444? sorry about this naive question, which steps are needed for that?

Thx
Tom

Yes it is very much possible, but prores encoder is not real time

Note that. Gstreamer used ffmpegs prores encoder.
gst-launch-1.0 videotestsrc ! avenc_prores_ks ! qtmux ! filesink
location=test.mov -e

Ola Shilvin!

Worked perfectly! the "test.mov" created is a ProRes 422 HQ, is it possible
to create in the ProRes 4444 codec option? ProRes 4444 support 12 bits per
channel or more and Alpha channel "Transparency" channel for Masks.

Thanks a lot for your help!

Tom

avenc_prores_ks Supports format: { (string)I422_10LE, (string)Y444_10LE,
(string)A444_10LE }. Use required format generate required test pattern.
