Hi, I have some GoPro Hero 4 videos (720p, 59.94fps, h264) that I have stabilised in Mercalli (standalone version), edited in Magix Vegas, exported to h264 AVI (using x264VFW codec) then converted to MP4 using HandBrake (which as I understand it is a container change only, not change to encoded data). Up to the AVI stage the footage shows nice smooth graded blue skies, but when I convert to MP4, even at a slightly higher bitrate, I get visible colour banding in the sky. Both versions at YUV with 8bit colour depth.
Any ideas ?

Why not export to .mp4 directly from Magix? What are you gaining from your AVI intermediate?

I couldn't find an option to do that. There are some Sony MP4 presets but none giving me unconstrained control over frame rate / bitrate etc
I tried HandBrake again using a quality-based encoding criteria rather than bit rate, and it came out nicely, no blocks. -
