4K Video Becomes Splotchy / Pixelated After Exporting

I use NeatVideo Plugin. It's basically luminance for video. (like lightroom has). 

What are your exact settings when you export the file? Please post screenshots of the media encoder settings you’re using. Like @averdhal said h.264 export is not that good in Premiere

-Or - Go to the Pegasus website and download the free trial from the link above and see if that works better for you

-or- Go to Black Magic design and download DaVinici Resolve and try that 

thank you

O.k Matt, we admit that this whole thing is a big conspiracy to confuse you. Satisfied? *sarcastic mode off*

I urge you to spend some time reading the User Guide for Premiere Pro so you can get a grip about the program, how it works, how to export, how to and how not to, etc instead of whining about that everyone here is corrupt and all they want is to mislead you, lie to you, giving fraudulent answers, etc.

We are here to help. If you want thelp, post a new thread and describe your issues with Premiere Pro and we will do the best to help you out. Hijacking other peoples threads and being angry will give you no help.

Lastly, don´t shoot the messenger.

I have no affiliation with Pegasys, i never had one, and i am not employed by them and has never been.

I am the average Joe end user and have bought their plug-in for my own hard earned money. The TS had a problem with bad output from the native Adobe Encoder and i just tried to provid a solution that may do the trick. Apparently it did since my answer were marked as the correct one.

I wrote clearly in my post that the Pegasys plug-in outperforms the H.264 encoder in Premiere Pro. It´s a personal opinion i have based on numerous tests i have done through the years. I had my opinion yesterday regarding the native built in H.264 encoder output and i have it still today since, well it is indeed sub par compared with non-MainConcept encoders. 

So yes, i would say that my statement, yesteryear and today, regarding the built-in H.264 means that i "admit" that the built-in H.264 encoder sucks.

Did this answer made you feel better? 🙂

Averdahl is just trying to give you suggestions to alternatives. He doesn't make any money by helping you.

 R_Neil is trying to help you by stating with complex scenarios you need to raise the bit rate of the export and not just use the standard bit rates of the presets.  

Artifacts are unwanted blurring , unwanted blocking, unwanted mosquito noise, etc. 

A bit of general information ... the Max Render Quality option is only of any use if you're doing any major frame resizing and are getting jaggies on diagonal lines. If you aren't doing any scaling/resizing, it doesn't help in any way. So ... normally  I would leave that off, and on the odd project, it can actually induce some artifacts you do not get without it.

IF you are exporting with some frame resizing, then ... check that option.

As to the export settings ... Averdahl is correct, a Cineform export uploaded to YouTube will always tend to get the better quality on that service. H264, as a long-GOP format, is very good a saving space on the drive or bits to upload ... but not for image quality of highly detailed and especially shifting intricate patterns like you get in water. So if you must use H264/265, and you have something like a good sized chunk of water, you need to keep the bitrate up pretty high. It will provide better service at higher bitrate levels, and of course, also larger files.

This is the artifact that is generated due to the compression type of the codec, try GoPro Cineform YUV 10-bit to see how it goes.
