Recently uploaded 4K videos are limited to 1080p on tv/chromecast (but are 4K on pc/phone)
I've been using Premiere Pro to create 4K 60fps videos for a few years now. So far I've uploaded more than a hundred of them to YouTube (most unlisted, but several published). And I've never had a problem viewing these videos in 4K on my TVs... until now.
Within the past few days, I've noticed that when I upload a 4k 60fps video to my YouTube channel (and then wait for 4K processing to complete), I can watch that video in 4K on my PC and phone, but on my TV the resolution is limited to 1080p. Chromecast , Google TV Streamer, and my TV's native YouTube app all limit the video to 1080p, but all my non-TV related devices can show it in 4K.
For example, a couple days ago I uploaded a 2 hour long 4K 60fps video. I waited several hours for 4K processing to complete, and then tried viewing the (unlisted) video on various devices:
Computer: I tested multiple browsers (Chrome and Firefox) on multiple computers and they all let me view the video in 4K. GOOD
Phone: My Samsung phone (S24FE) lets me view the video in 4K. GOOD
Quest 3 (VR): The Quest's YouTube app lets me view the video in 4K. GOOD
TV: I tried Chromecast on a 1080p TV, Google TV Streamer on a 4K TV, and the native YouTube app on the 4K TV and they all limit the video to the 1080p stream, which looks awful. They don't let me select anything above 1080p. BAD
Meanwhile, my older 4K 60fps videos all play beautifully in 4K on the TVs (whether via Chromecast, Streamer, or native app). The 1080p TV downsamples, of course, but it's clearly drawing from the superior 4K stream rather than the ugly, artifact-laden 1080p stream. It's only the recently uploaded videos which are being limited to the 1080p stream, and only on TV.
So, why can't my TV (and Chromecast and Google TV Streamer) detect and access the 4K stream, while my PC, phone, and Quest 3 can? It's exactly the same video.
I also tested both long (2 hour) and short (2 minute) videos and get the same behaviour. So it's not a matter of video size. And plus, I've uploaded dozens of 2+hour videos in the past, and never had this problem.
My most recent video is ready to go. It's unlisted, but not yet published. I don't want to publish it until I know it will be viewable in 4K on TVs. However, so far I haven't been able to view it in 4K on either of my TVs. So I'm at a stand-still.
I actually re-uploaded the video today, and got the same results. The second copy plays in 4K on my computer and phone, but is capped at 1080p on the TV/Chromecast/Google streamer.
This is very strange, and very frustrating!
I am currently re-rendering the video using Premiere Pro instead of Media Encoder, to see if that makes a difference. (Should it?) It'll take me a day or so to find out!
In the meanwhile, any ideas what's going wrong, and how I can fix it?
Thanks!
