Hello,
My full-frame overlay filter command line is working for mp4 sources.
But no overlay is visible for mxf/prores sources.
-vf movie=overlay.png, scale='trunc(oh*a/2)*2:min(in_h,720)' [o]; \
[in] scale='trunc(oh*a/2)*2:min(in_h,720)' [v]; \
[v][o] overlay [out]
Assuming that it's a colour space/pixel format related issue, I've naively
tried to set the output pix format explicitly via
-vf movie=overlay.png, scale='trunc(oh*a/2)*2:min(in_h,720)' [o]; \
[in] scale='trunc(oh*a/2)*2:min(in_h,720)', format=pix_fmts=yuv420p [v]; \
[v][o] overlay [out]
but this has no effect.
Can anyone help?
TIA,
Steven
