Welcome to Entropia Unrealverse

They always downsample to reduce the bandwidth. To get the best possible results you should meet YouTube's recommendations: https://support.google.com/youtube/answer/1722171 All of them except the bitrate, the bitrate should be a low a possible by maximizing compression. YouTube uses 2 codecs for their videos: AVC and VP9. VP9 usually results in better video quality but as it's more 'expensive' for YouTube it's usually only applied to videos that the algorithm deem worth it. However, there are parameters you can influence to trigger VP9, like meeting all the recommendations. In addition the most important is resolution, which best should be 4k (3840x2160). You can btw check the used codec by right-click on a YT video then click "Stats for nerds". To compensate for downsample bluriness I sometimes add extra 'crisp' using ffmpegs unsharp filter and and little bit more conrast with the eq filter. To get a visually lossless source file in the first place I record using OBS, encoding with x264 and CRF (constant rate frame) set to 19 to retain high visual quality, the CPU setting to "ultrafast" (which is least taxing to CPU) resulting in huge file sizes. With "ultrafast", high resolution and high level of detail in the game the disk write rate can be a bottleneck. I apply the max compression and filters and stuff afterwards in a second step, with ffmpeg X264 encoding, CRF also to 19 but CPU setting to veryslow. Pfft, I've got no time, sorry for this messy explanation, I shall do better as soon as I have the tome :)

The re-rendering of the EU EU5 vid was just one line of commands:

ffmpeg -i d:/Videos/2021/euue.mp4 -vf "crop=720:405:0:439, unsharp=3:3:0.3:3:3:0.3, scale=3840:2160:flags=lanczos+accurate_rnd+full_chroma_int+full_chroma_inp, unsharp=3:3:0.3:3:3:0.3" -c:v libx264 -preset veryslow -crf 19 -maxrate 24000k -bufsize 16000k -use_editlist 0 -movflags +faststart -c:a aac -f mp4 d:/Videos/2021/Entropia-Universe-Unreal-Engine-5-First-Video-4k.mp4

 

Yet another Hiryuu comcept art.

 

New one (actually yet another perspective of what was already published in early October):

 

First vid showing character movement:

 

What's this?
