Finished testing the Gif2Channel tool.
I used "EximiousSoft GIF Creator v5.76" to make the Gif animations and imported the gif file to spayro's tool.
All worked fine, however the end result lacks the smoothness and quality. Moreover the banner only without sound was about 14 MB!!! and the gif is trimmed in the end (output channel duration is short)
Smoothness - that'd be because it only changes every 10 frames (presuming the same BRLAN is being used as sprayosam posted on the previous page). Change it to every frame (or every 2-3 frames; presuming Wii displays at 60 fps [guess], you could do it every other frame to achieve 30 fps in the animation - possibly closer to what the GIF is displayed at typically) and it'll be much smoother.
Quality - Make sure GIF is exact right resolution. Also, for some reason the "AnimPicture" pic in the BRLYT is only 480x280 whereas the full resolution is 832x456. Possibly increasing the "AnimPicture" resolution to the full resolution would improve quality? [I do not know for sure, I don't know what the max resolution for banners is] Also, using different qualities of TPL
File size - I covered this already, it's gonna be huge. Especially if you increase the resolution and TPL quality.
Note that it may be OK to leave out some frames, seeing as chances are there are at least a few frames where nothing much happens. But you'd probably have to do this sort of thing manually. It could improve smoothness and also file size.
EDIT: Also note that the Wii can only take channels up to a certain file size without crashing. Dunno what that size would be.
This Gif2Channel tool, despite being great and cool and fun, is not very practical.
Still I think what's missing in this area is a tool similar to the Gif Animators that can generate the animations without using sooooo many tpls.
Thanks Spayrosam
Hope to see updates for this tool in the future.
Ideally, some simple GIF generator would be adapted to generate animations using separate materials and then generate a BRLAN from the animation instructions. But that'd probably be a huge task, and it's unlikely to happen.
