I kept the image sizes at 480p, on the SGS2, it's MUCH MUCH more crisp compare to the 256p. Also, the initial choppiness issue is resolved as well.
(On SGS2, if you pay close attention, you may notice *very minor* choppiness for like a fraction of a second when the animation appears, but it's mostly non-noticible since the image was still in the process of fading in )
Here's what I did:
- Changing hue: The hue is now changing constantly, instead of one single color.
- Size: Cropped the original 480x800 to 480x480, getting rid of some unless black area.
- Image format and quality: Used JPG instead of GIF, since jpg files are smaller compare to gif, this allows me to keep the image resolution at 480p. Down-graded the jpg quality to get the file size down. The resulting zip file at 480p is now even smaller compare to the one at 256p posted by the OP. Doing so drastically decreased both the choppiness magnitude and the duration. Making this virtually butter smooth
- Frame rate: Kept at 30fps instead of 24fps since i was happy with the smoothness already.
Disclaimer: I only tested this on my sgs2, so i'm not sure how well it'll come out on the Evo. Also, i'm not responsible for any damage to your phone, so use it at your discretion.
The attached zip file is CWM flashable zip file, not sure if it works with evo, but the bootanimation.zip can be extracted from it, just look into the data folder inside the zip and you'll find it.
Anyone who tried this please let me know how it came for them
SPECIAL THANKS to aph for his work and the inspiration, as well as Dysgenic for making the original animation.
