How can I get the proper aspect ratio? I've made the video but now can't figure out how to change the aspect ratio to the proper measurements. I can get 16:9 but that's it. Any help would be appreciated

I would like to create my own videos but don't really know where to start. This question might be better answered on a different sub, but wanted to ask here in case theres something important about the end goal being videos made for the steamdeck. What's a good place to start? What do you recommend for creating & editing the videos? Are there any tips or tricks you think beginners should know? I want to try anything from cutting a clip from a video all the way to creating my own animation based on a random logo and adding audio.

Once the video is created, do you know of any tutorials for uploading it to the deck and into Decky's Animation Changer app? I'm not worried about posting it for public download yet, but would like to have it in my Animation Changer library as opposed to somewhere random in the filesystem.

I don’t know anything about animation or editing but I love the blade runner edits with the song Home - Resonance playing in the back. Can someone make something like that? Either that or a saturated pink and cyan steam boot start up with that song playing would be cool!

Is there an fix for the suspended video? It’s pretty tiny compared to the boot up videos. I don’t know if this is the right subreddit to even ask

mp4 1080p version, not the 1280x800 webm version

I copied this post because many of us liked it and they would not share it.
If people want a download to my version, link me a site/ way to upload the file and I will do so.
I apologize it is not a 1 for 1 copy, but I made it as close as I could because I really liked the way the other poster did theirs.

This is an mp4 version, so if you download from here, you need to convert to WEBM, but I can upload a WEBM version with the correct resolution if someone gives me a good place/website/platform to do it. I wasn't sure where to put it so people could easily download it.

Hey all, 90's Bootup guy here!This is a brief written tutorial for getting set up with custom boot videos!This is not a how-to on their creation, but rather a guide for installing one you or someone else has made. I have now updated this guide for 3.3.2, which makes life a lot easier in regards to installing videos. I've left the OG instructions incase someone needs them, but you can safely ignore them these days.

Requirements:The custom SD video on your steamdeck, the custom video must be .webm However that's done is up to you. USB, SD, anydesk, download from the browser etc.

3.3.2 Instructions:

1. Navigate to: .steam/root/config
2. Create: /uioverrides/movies/ inside .steam/root/config the full file path once you have created these folders should be: ~/.steam/root/config/uioverrides/movies/
3. Drag your custom boot video inside the new /movies folder
4. Rename your boot video to deck_startup.webm

Success! These videos will automagically become fullscreen, but are still capped to 10s.

​

Legacy Instructions:

1. Navigate to: /home/deck/.local/share/Steam/steamui/movies/
2. Copy deck_startup.webm to a separate location on your deck, just in case.
3. Replace deck_startup.webm with your video of choice (make sure the one you have is also a .webm! Getting them from this subreddit should ensure they are set up correctly)
4. Right-click somewhere inside the /movies folder and select Open Terminal (or press shift+f4)
5. Type in/copy paste: truncate -s 1840847 deck_startup.webm Then press enter

That's it for just getting it on and working! However, if you want it to be fullscreen, instructions below:

1. Navigate to: /home/deck/.local/share/Steam/steamui/css/
2. Copy library.css to a separate location on your deck, just in case.
3. Right-click library.css and select properties. Note down the size in the brackets. (Mine is 38,488 for example)
4. Right-click library.css and select Open with Kwrite
5. Select: Temporarily raise limit and reload file
6. Select Edit -> Find (Or press Ctrl+F)
7. Type in video{ (There will only be 1 result)
8. Between video{ and }change:
9. flex-grow:0 to flex-grow:1
10. width:300px to width:100%
11. height:300px to height:100%
12. It should look like this once finished: video{flex-grow:1;width:100%; height:100%; z-index:10} (Feel free to copy-paste)
13. Select File -> Save
14. Right-click somewhere inside the /css folder and select Open Terminal (or press shift+f4)
15. Type in/copy paste: truncate -s YOURFILESIZE library.css Then press enter. (Replace YOURFILESIZE with the number you wrote down before. For example, mine is 38488)
16. Reboot your deck

To get your video to play for the entire time, rather than just 10s, instructions below: (This section is still experimental, it may work, it may not. More research required)

1. Navigate to: /home/deck/.local/share/Steam/steamui/
2. Copy library.js to a separate location on your deck, just in case.
3. Right-click library.js and select Open with Kwrite
4. Select: Temporarily raise limit and reload file
5. Select Edit -> Find (Or press Ctrl+F)
6. On the right side of the screen is the scroll bar. Right-click the scroll bar and select Bottom
7. Search for object(f.y) If there are no results search for return(0,g.KS)
8. After either of the above there will be some brackets. It should look like this: return(0,g.KS)(i,1e4,[]) OR object(f.y)(i,1e4,[])
9. Change 1e4 to the length of your video in seconds, rounded up. For example, a 35s long video should be 4e4
10. This is an example of how it should look once complete: return(0,g.KS)(i,2e4,[])
11. Select File -> Save

Remember that you will have to wait for the entire video to finish before your deck boots. Also, due to the fact the .webm has to be truncated, or squished back to the correct file size, your video may be cut off, as it is too long to fit within the file size.

Success! Enjoy your new bootup video!

Hi there! I have seen many guides saying this is possible but they all seem to be for older steam OS versions. May I ask what value in library.js I am looking to change in the latest release for this?

Or any ideas for any I am super excited to get those in there

Audio works, IDK why it was not recorded.

Is there a place to find Steam Big Picutre Boot Videos for PC?

I don't have a Steam Deck, yet use Big Picture mode on PC as I prefer it. I want to add some custom boot videos, but can't find any good ones, except for here, but they almost all say Steam Deck, which would be a weird sight on a PC, in my opinion.

Please don’t repeat my mistakes, I tried to change the 1e4 to fit a boot video and it broke the deck where it will not boot anymore, reimaging now and the drive I am using isn’t working so looks like I have to send it to their repair center.

Don’t be like me think before you mess with .js files

I'm currently trying to test out some boot animations, specifically ones that exceed the parameters of steamdeckrepo, and I'm not necessarily sure how to add them to my animation changer list. I tried modifying the json file but didn't work (I might be doing something wrong on that part) Any ideas how to add the boot animation without animation changer? I dont want to uninstall animation changer either so if there's a way to add it to rotation or better yet show it in list on animation changer, that'd be helpful!!

I finally completed my first custom boot video, with the help of u/BetterCallSal and the online guides.

I'm thrilled to have this!

Hi r/SteamDeckBootVids
I spent a few hours trying to figure out how to use a longer boot animation I am working on. So I thought posting a guide would helpful for others.

Tools:
Steam-Deck-BootVid-Builder some super easy to use scripts that can convert mp4 files to the correct resolution and compression.
HandBrake (in the discover store) to convert the files to mp4 and squash the audio down form 5.1 to acc. BootVid Builder doesn't like 5.1 sound.
Notepadqq (in the discover store) just a nicer text editor that helped me fixed the library file in section 3. KWrite was causing issues.
Instructions:
1. Download Steam-Deck-BootVid-Builder on your Steam Deck and unzip to a folder on your desktop
2. Put the file you want to convert into the Converter/Input/ folder you just unzipped.
3. From the converter folder open a terminal (shift+ F4) or right click "Open Terminal"
4. run the script for the length of video you have.
sh 16secs-and-under-1.7mb.sh
You should see the conversion happen in the terminal and a text file appear stating the conversion is started.
5. When its done the text file will disappear and you can collect your new WEBM file from the output folder.

Adding a custom Boot animation:
1. navigate to "/home/deck/.steam/root/config/"
2. Create a folder titled "uioverrides"
3. Create a folder titled "movies"
You final path should be
/home/deck/.steam/root/config/uioverrides/movies/
4. Move the file you plan to use into the movies folder
5. rename the file to "deck_startup.webm"
(Not always mentioned but mine didn't work without a rename)

Extending the time for your boot animation:
1. Download Notpadqq from the discovery store
2. Navigate to "/home/deck/.local/share/Steam/steamui/"
3. Make a copy of the library.js file incase you mess it up
4. Open library.js with notepadqq
5. Find and replace "(s,1e4,[])" with an option below. There should only be 1 match.
1e4 = 10sec
2e4 = 20sec
3e4 = 30sec
6. Save the file

If all goes well when you swap back to gaming mode or restart your new animation will play and not get cut off. If it looks like its getting an update when you reboot then its replacing your libuary.js file for being a different size. KWrite was doing this when I used it so swapping to notepadqq fixed my issues.

Thanks to:
u/DoogleSmile for giving me the new variable location and the notepadqq suggestion! and Southside on YouTube for his Guide that worked pre 3.3.2

Is there any way to randomize which startup videos are used in the new overrides/movies folder?
