Playing the local file on your PC looks nice and crisp, but why do your 1080p videos look so bad, blurry, pixelated, etc once you upload them to YouTube? TLDW: you did everything right, it's on YouTube's end, you gotta force upscale your 1080p videos/streams to "false" 1440p. This forces YouTube to use their much better VP9 codec instead of their resource-cheap AVC1 codec, which is the default for 1080p videos and streams. I don't know of any way to retroactively force YouTube to use VP9 on a video you've already uploaded. If anyone knows, leave a comment and I'll pin it so others can learn. Samples are from my War Thunder streams, I had to learn all of this the hard way. good luck out there further reading: • Is Youtube Destroying Your Video Quality? ... • How To Fix: Loss Of Video Quality After Up... • YouTube COMPRESSION - Tips and Tricks for ... • Low Video Quality After Video Upload On Yo... 00:00 intro 00:09 basic explanation of what's happening 00:18 AVC1 1080p sample 00:38 VP9 "false" 1440p sample 00:49 how to fix 01:03 how to verify you're using the correct codec after you upload
