I believe I've figured out how to make a custom thp (finally)! It takes a long time & I haven't yet done so but I thought up the main idea! (Don't do so till I can see cuz I will call you on it)
Heres what I got so far:
1: Get all videos you want parts of converted in 1 type of image (jpg, png, gif, ect)
2: Mix & match much like it would look like (look at Brawl's original intro for info). MAKE SURE TO KEEP THE FIRST FEW SECS (till right after the SSBB logo) THE SAME FOR REFERENCE!
3: Once done convert the finshed video (all images of course) into 1 thp with the selected music (can make a spare that is not a thp to test on your computer)
4: Test in game. If it still looks good HYES! The thp is made!
So far this is what I'm planing on trying. I'm forced to use things like Windows Movie Maker to convert so I don't know how it will work but I believe (if this works the way I plan) it WILL work. Tell me what you think below & I'll see if I can use your ideas & we can work together to make a new way of thp hacking!
Doing this for my own personal intro & I hope it works for then I & anyone who helps out will be awesome!
