Im still experiencing this issue on my two decks. Only the default movie seems to work. Other ones play only sound while the deck boot logo is still static on screen and only the final bit of the video suddenly plays before the boot
I have a 256 LCD deck and a 1TB Oled. Both always on stable. no plugins or weird modifications. This has been happening for months
I've tested the startup movies I have access to and found this failure affects both the Saturn and OG Big Picture startup movie. They play back correctly during Preview / Wake, but are obfuscated by the Steam Deck logo on boot (only seeing the tail-end of the startup movie).
Edit: Found two more (Paddles and Worms) that are also affected.

I second this issue, I have a lot of custom animations (randomized at shutdown by a decky plugin), some of them as long as 20 seconds, and sometimes the logo remains on-screen for upwards of 5 seconds while the audio plays.
I think that the issue is the animation not playing while the "Logging in..." throbber (etc) would be shown, so I'm using "Change Account" into the "Who's Playing?" screen before rebooting, and that makes it play correctly more consistently, but it sometimes still happens anyways (likely "Waiting for network..."?). I'd have to do a deep dive to figure out when it happens more specifically.
Hey everyone, I was struggling with this exact same issue (audio plays but black screen on cold boot/switch to Game Mode, but it works perfectly when waking from suspend).
I managed to fix it by asking Gemini for the solution, and it told me to re-encode my video with a specific ffmpeg command. I honestly have no idea why this exact combination of settings works, but it completely solved the problem for me
the code:
ffmpeg -i MYVIDEO.webm -c:v libvpx -b:v 3M -vf scale=1280:800 -pix_fmt yuv420p -c:a libvorbis -b:a 128k deck_startup.webm
Just swap YOUR_VIDEO.webm with your file's name, run it through Konsole, and drop the new deck_startup.webm into ~/.steam/root/config/uioverrides/movies/. Hopefully, this saves someone else the headache I went through.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
A some time ago I restored factory state on my Steam Deck LCD (it was SteamOS 3.5) and since then I have a problem with startup videos.
I can see black screen for the first 2/3 seconds and sound of boot video in the background. After that, I see on the screen the end of animation. Only the default boot video works properly, I bought Saturn startup from points shop, and it's not working as it should (I can see animation from the blue dot connected with sphere). Some customized boot videos (stored here /home/deck/.steam/root/config/uioverrides/movies/) also not working as expected.
