Getting noises in exported file

I'm facing a problem exporting 4k timeline to h264 "matching source high bitrate".

I'm getting noises in some frames.

After several trials of different h264 settings i found the "match source adaptive high bitrate" to solve the problem. but it comes with a heavy penalty - the size of the file is 6 time bigger!!!

Any idea?

Thanks

You need a higher bitrate than 10 for good results for 4K. Besides the problem you uploaded, take a look at the boat and the loss of details and the amount of macro blocking. Try H.265 to use lower bitrates.

4K=big video files.

Both files are 4k!!!

The first one - "h 264 match source high br" - comes out smaller than an mpeg 1920*1080!

Uptill now with very good results! no noise! (anything to do with the new version?)

Following your advice I was trying to lower the BR but less than 63.3 BR (which is the adaptive setting) 50 BR the noise remain!

I was trying also facebook, vimeo, youtube 4k ultra hd settings and h 264 high quality 4k but the noise is still there.

Any other idea?

Yes, download a trial version of TMPGEnc Movie Plug-in AVC for Premiere Pro and export. This encoder is superiour to the standard H.264 encoder in Premiere Pro. No watermarks or other limitations in the trial version.

The built in H.264 encoder in Premiere Pro falls apart on the video you have with much details. Water, sky, grass and tree tops are always hard to encode.
