Premier Pro h.264 export codec and pixelation problem

Hi everyone,

I'm editing some 4k videos by DJI Mavic Drone and I have a loss of quality just cutting and exporting video with h.264 codec. The drone record videos in .mp4 or .mov h.264 60Mbps. In the original videos  I've no problems with sea or sky backgrounds, in the edit ones I've a pixelation problem on these, although the same export setting (Best rendering and maximum depth, VBR 2 pass 60Mbps). I tried also with TMPGEnc H.264, but the final result was the same. I need as final form a .mov or .mp4 video. Moreover I don't understand why when I choose Quicktime form H.264 codec doesn't appear and if I use DNxHR or GoPro Cineform codec I've a huge video file (3gb or more vs 200-300 mb in .mp4) that cannot be opened.

Thanks you

Hi, I tried exporting WITHOUT "usa massima qualita di rendering" and "rendering alla profondita massima" on, but the result was the same, moreover I set at 5 "distanza tra fotogrammi chiave", nothing change . The quality on the beach or rock is amazing, the blue water aside remain pixelated between different color gradation! I've a better result using TMPGEnc H.264 codecs, but not the same level of the original file, also setting an higher value in Mbps (80-100).

I noticed this loss also without apply Lumetri Color, is there a way to reduce this problem using these filters?

Is it normal that selecting Quicktime form H.264 codec doesn't appear? I would try to export in .mov

Here the exorting settings for H.264

As crazy as it sounds, have you tried exporting WITHOUT "usa massima qualita di rendering" and "rendering alla profondita massima" on? I know that seems counterintuitive but try exporting without those on. If that still doesn't do it, you might try turning on "distanza tra fogotgrammi chiave" on and set it to a lower number like 12.

H.264 inside a quicktime container was removed as an export option in a recent software update. Adobe dumped a bunch of older options since QT is an aging format. In 99% of cases, you'd rather have an H.264 file in an MP4 container than QT anyway!

Can you show us your export settings window? Ive got a DJI Mavic myself and haven't had these sorts of issues. I mean obviously when H.264 gets recompressed, there can be a dip in quality, but not usually a major significant one (unless you perhaps applied any effects to the clips? Lumetri Color perhaps?).

One thing I CAN answer for sure for now is about DNxHR and Cineform... those are considered master/archival codecs that 1. are VERY high quality but 2. are ginormous files and 3. aren't usually compatible with consumer software. So in many cases, you cant export with those settings and then immediately open it in something like Windows Media Player or Quicktime Player. You'd need to either re-import into Premiere or use VLC.
