Thank you very much.
If I use a 10bit YUV444, is it converted/processed at 8bit 422 by the timeline (no filter) ?
If I use 16bit images, are they also processed at 8bit. If I export them back to 16bit from shotcut, is it ok to assume I now have an 8bit file in a 16bit “wrapper” ?
EDIT : I found this post if you are interested.
CPU filters operates at 8bit per pixel
GPU filters operates at 16bit per pixel
You can export at 10bit in the Export Other tab:
mlt_image_format=rgb24
pix_fmt=yuv422p10le
