We have a transparent PNG file with a drop shadow. The drop shadow when
overlayed onto a Mov is rendering very dark.
This is usually related to whether the input color pixels are straight
or pre-multiplied.
Try
ffmpeg -I TEST-1.mxf -i test-1.png -filter_complex
'[1]premultiply=inplace=1[img];[0][img]overlay' -c:v libx264 -profile
high10 -map '[out]' out2.mp4
