..... I've done some work to your video. Firstly without wishing to "teach you how to suck eggs" I must make the following comment.....You say that the video is in HD (1080p), that statement is almost sudden death to boot animations because the number of frames that are produced by a 1080p process is huge compared with the number of comparable frames produced by "Standard Definition", I have produced several animations both for my phones and my tablet using clips I have captured from BD disks and the size of the animation jumps up alarmingly. So what I did with your video was as follows..... From the original files I deleted 224 frames from various parts of the video, trying to keep that figure to as many near duplicates as possible.....I then used PhotoScape ("Batch Edit") to resize the frames to 720 x 1280 .....I then built a boot animation using those frames ..... this built ok the only trouble being it was 95 Mg in size which is utterly outrageous!..... I then processed the frames through another graphics program (Pixillion Image Converter Plus) with which I was able to decrease the original definition and finished up with an animation which was 12 Mg in size which is acceptable.
JPG's from HD files are high quality, which can make for huge animations, and can stand having the definition reduced.
The two attached files are (1) The finished animation (the title tells you that one) and (2) The individual jpg frames altered as to size and definition and zipped (again the title is self explanatory).
I appreciate that the final effort might not be as you would wish but possibly you can work with the individual frames to achieve a result which you prefer. Feel free to use or adapt any part of my animation if it helps you.
