  Hello Guys , I was very excited by android 8.0 and i also love oreos!
  So long story short , I made this bootanimation for my device that looks like Android Oreo boot animation.
  
  I tested this on my Moto G4 plus and my friend tested it on Nexus 5 and it worked great for him.
  I dont have any other device to try so i want you guys to give it a go and let me know how it works!
  
  So the problem is that i am not very good at making bootanimation , i know how to design but with the bootanimations i am new. So i thought you guys could help me with the animation and how to make it run smoothly on all devices.
  I dont know much about the desc file also i just tried to make one using the default android bootanim and it worked.
  
  These are the things that i need help with
  1. Making the size of the zip small
  2. Making such that part2 runs full even if the device is fully booted , i did that for the 1080p one and it worked but not for the 720p one.
  3. Making the bootanimation for 720p devices , i have resized it and it plays also but the point 2. is not working. i.e. the part2 sometimes plays fully sometimes doesnt.
  4. Porting it for 1440p devices, I will give the resources (the png files and the zip) and if someone can port it , it would be awesome!
  5. Make the animations run at 30 fps .Right now i make the animations at 20fps and run them at 60 to make them look smooth.
  
  It would be really helpful if you guys can help me with the process and i will credit you in the video and at the end of this thread also
  Cheers

  Let me know what you guys think of the Bootanimation any Suggestions are welcome.

  Wow! A beautiful, gorgeous animation.
  
  I'll give you some general pointers, based-on my experiences with animations on the N5:
  
  - For full-screen animations, I recommend frames that do not exceed dimensions of 720x1280 pixels. My N5 (and many others) lock-up with anything larger than that. You simply scale it from 720x1280 to 1080x1920 in the desc.txt. Maybe I'm blind, but I really can't tell the difference between 1080x1920, and 720x1280 scaled-to 1080x1920 ***ON A 5-INCH SCREEN***.
  
  - I've had issues when the number of frames in folders. For non-looping folders, I recommend not exceeding 199 frames; for looping folders, I try keeping that value under 100. There are animations that get away with many more frames in a folder, but those animations have very small frame sizes. For full-screen animations, keep a tight reign on frame counts.
  
  - Keep the fame image sizes small. I try and target under 120KB per image, and much less if I can. You can save as JPG (and reduce quality), reduce the image sizes by scaling or cropping, or reduce the image palette (number of image colors).

  I'll address your questions:
  
  1. Smaller zip:
  
  Scale the images: I scaled your animation from 1080x1920 to 720x1280, and the zip size decreased from 21MB to 12MB.
  
  Optimize: I post-processed the scaled images further with "optipng" (in lossless mode), and it further reduced the total archive from 12MB to 10MB. Optipng looks at the palette, and determines how best to save the image.
  
  Reduce the palette: Your images are RGB/24-bit. You could reduce the frames to 8-bit (256 colors), but you'll run into potential issues with banding of gradients. Optipng does essentially the same thing in a "nicer" way.
  
  Scaling the images and optimizing them, while keeping them as PNG files is probably the best route.
  
  2. Making part2 run on all devices:
  
  Try reducing the number of frames in that folder, or shorten that segment of the animation. 227 frames is too many.
  
  Your "part2" folder is the largest part of the animation. With the "c's" in the desc.txt, the last folder is the "close-out", or conclusion to the animation. The "c" identifiers tell the phone "do this until you hit this milestone, then do this". That last folder should be brief; I'm usually seeing it used after coming out of a long loop, with a quick transition from the loop to a logo of some type. The phone also expects it to be short, or it would stay on the loop longer. The 720p phone might be thinking "I'm not waiting for this final folder to complete; I'm ready to go to the lockscreen NOW". At 60 FPS and 212 frames, that's just under 4 seconds; perhaps that should be 2 seconds or so. Dunno. You'll have to play.
  
  3. Making it run on 720p devices:
  
  Could be solved by #2 above, or another solution. I'm looking at your desc.txt, and I don't think it's right.
  
  

  Code:

  1080 1920 60c 1 0 part0 #FFFFFF -1c 1 0 part1 #FFFFFF -1c 1 0 part2 #FFFFFF -1

  
  Let's look at this.
  
  First, get rid of the "#FFFFFF -1" on every line. You're running a full-screen animation, yet you're pulling-in a white background. Not needed, unless you're letter-boxing (cropping) the animation.
  
  Your "loop" is folder "part1", yet you're not looping it. "c 1 0 part1" should be "c 0 0 part1". If there were "p's" instead of "c's", a "p 0 0 part1" would never get to the next folder; that "c" tells it to "continue looping until you hit the next event"
  
  I think you're desc.txt should look like:
  

  Code:

  1080 1920 60c 1 0 part0c 0 0 part1c 1 0 part2

  
  4. Porting it for 1440p devices:
  
  All you need to do change the desc.txt line from "1080 1920 60" to "1440 2560 60". That's it. Either the 720x1280 or 1080x1920 frames will work fine. I'd still probably use the smaller 720p frames, but the 1080p frames will probably work. Again, I question whether anyone can tell the difference between 1440p frames and 1080p frames (scaled to 1440p) on a 6-inch screen.
  
  5. Make the animations run at 30 fps:
  
  Delete every other frame (odds or evens) in the animation, and change "1080 1920 60" to "1080 1920 30". Easy.
  
  Some things to look at:
  
  - Your loop, "part1" is very short, considering it's probably the longest thing that folks will see while booting. I'd love to see more of the pizazz you have in folder "part2", frames 48-77, incorporated into folder "part1"
  
  - In "part2" frames 257-274 are identical. That's 18 frames. Removes frames 258-274, and in the desc.txt, you can change the last line from "c 1 0 part2" to "c 1 17 part2"; that will run the frames through once, then hold the last frame for 17 frames duration. And you get to kill 17 frames.

  I've tweaked the animation a bit. It's staged, with a definite loop; the Google logo will now appear right before the lock screen.
  
  Let me know what you think:

  Woah guys no, u don't flash the zip, use a root file explorer or whatever to install the animation. U simply
  download the bootanimation.zip copy it
  
  goto /system/media
  
  Make sure the system is mounted as rw
  
  find the original animation and rename it to boot animation.zip.bak
  
  Paste the downloaded bootanimation.zip there
  
  Change the permissions to 644 rw-r-r
