Thanks very much. I was hoping to restrict the output using ffmpeg and not ffprobe; mostly so I could make a proxy with overlay and metadata text file at the same time.
My question regarding bit depth was because the filter doc shows values between 0-255 which is cool for 8bit values, but 10bit obvs higher. Thanks for your help I will give it a whirl with a 10 bit file and see what comes out.
