D4 Soft (or D4rKn3sSyS) from XDA has converted his Boot Animation Installer/Manager into an app for use on rooted devices. I tried it and it works GREAT. Only way to imporve it would be to include on screen buttons, as the only visible things are "swipe down to X". To apply, you need to press the "3 dot" menu to Apply, Backup, etc.
The download link is available in the second post on that thread over on XDA. I didn't include it in this post as I did not want to affect his "viewed" stats over there.
Copied from: [2.2+] Bootanimation Manager - xda-developers is a easy tool for managing Bootanimations
PC Version no longer supported
Android OS [2.2+]
ANY File explorer with txt/csv mimetype (like Root Explorer or OI FileManager)
Human or similar
Backups current bootanimation to SD (both, system and data bootanimation)
Installs new bootanimation.zip (no need to change name)
Show Preview of any Bootanimation (no CWM files, no MIUI ones)
Save preview of current showing bootanimation (adjustable framerate since 1.1)*
*This feature needs time, because we're saving frame by frame, so it depends on the size of the images (480x800 will be slower than 240x320)
Build bootanimations from PNG sequence - Almost done right now, still a bit messed up at organization of frames
Build bootanimations from GIF
Get bootanimation default size from current bootanimation on phone **
**Not sure if will work
EXAMPLE OF PREVIEW.GIF:
Yes is 11mb gif ! (and I've made some 25mb ones)
