    Problems with mixdown and output!

    I have a series of 7 min to 15 min videos with sound I want to export as mp4 for use on Bright Sign media players. They all have numerous video and audio tracks so I have been making mixdowns before exporting. I then export each mixdown to the desktop as h.264.  What I find is that many of them have wierd artifacts in sections with long fades or dissolves--they stutter and look pixelated.  All still and video shots were transcoded to Apple ProRes, from sources as diverse as XDCam, Go Pro and iPhone. I'm facing a deadline and need to get clean exports of these sequences.  Any help is appreciated. Thx

    Dear Job - Thanks for your quick reply.  After a bit of figuring today I solved the problem by NOT mixing down my sequences and exporting directly to h.265.  It worked beautifully.

    Best, marluc
