Here is my contribution to this thread,
Regarding this particular bootanimation that I posted
This GIF was custom made for me from a friend a while back it was inspired by the spinning logo on the jumbotron of the Bell Center, and thought it would be cool to have it as a desktop background. Just 2 days ago I stumbled on it by mistake and decided to try to use it as my boot screen (it looks very sweet too).
as for details, regarding it, there's a total of 100 frames of 480x400 resolution
A few things I would like to note that could probably help a lot of ppl or maybe it's just me
I went thought a lot of trial and error to try and understand why I was getting a black screen everytime until it finally worked.
First some tool that can help you guys.
Both tools are available as a standalone zips without the need to installing them.
This tool will allow you to rename one or more files, it's extremely powerfull, although takes some getting used to at first
Bulk Rename Utility
This will allow you to extract an animated GIF into PNG files or other formats
GIF Frame Extractor
Now one thing to note that took a long time to figure out was that you gotta follow the naming convention of the original bootanimation.zip of your rom, since I checked out a lot of animation and saw they each ha diff names in the folders part0/1 figured as long as there's a sequential numbering for the files that the animation will kick in.... unfortunately NO, save yourself a lot of headaches, extract the bootanimation.zip from your phone look at the naming convention and rename your files to match using the tool above.
