[shotcut]

@brian

there will be a conversion to YUV if you use the timeline

No, the track blending is using frei0r.cairoblend, which is RGB, and there is an optimization to not blend if not needed. You are correct about all transitions at this time. I made a list of the YUV filters in this post:

GoPro, full color range and pix_fmt=yuvj420p -- what to hope for and what to avoid?

pix_fmt=yuvj420p is stable, but you should also add mlt_image_format=rgb24. RGB (in the context of Shotcut and its libraries) are full range. Even though a filter might need to convert to limited MPEG/broadcast range to do its processing, it will expand back to full range in RGB. The result of this operation is some slight degradation due to something called quantization error, but it will largely be negligible. It should not affect the vibrancy you are concerned about, but it is less than ideal…
