Questions about Thwimp and Encoding THP with a new subvideo causes ridiculously high framerates??

[AaronRules5]

Hello there!

I just started using Thwimp in order to attempt to mod Mario Kart Wii.
I got all the files I needed for Thwimp, and set up the configuration correctly.

I first decided to try and rip a THP into MP4s and then re-encode it into a THP to know if it works correctly.
So I ripped all battle\battle_select.thp subvideos individually, and renamed them from:

1. "battle_select_A1.mp4" to "battle_select_A1_1.mp4"
2. "battle_select_A2.mp4" to "battle_select_A2_1.mp4"

Notice: It seems like I have to rip each subvideo manually in order for the re-encode to work afterwards.
Ripping a THP into a single MP4 by selecting "All" in the Special Presets instead of ripping each subvideo individually
seems to make re-encoding not possible. If I am wrong in this assessment please let me know!
It would be nice to not have to rip each one individually for re-encoding.
Perhaps I can do it in batch through the CLI mode, but I may not want to have to do that.

Anyway I did this and it seemed to work perfectly fine.
It ripped each subvideo fine, and I was able to re-encode into a new THP!

Problem is when I tried editing one of the subvideos.

I'm not sure which editing software you use to create/edit subvideos yourself but this is what I did...

1. I put the original subvideo in VEGAS Pro 17.
2. I created a new track with a test video, and resized it to fit the screen via Track Motion.
3. I then tried rendering to 496x120 59.94fps. Vegas only let me render at a minimum of 496x144.
4. I then put the new rendered video into Handbrake.
5. I changed the dimensions from 496x144 to 496x120, and removed any automatic cropping.
6. I removed the empty audio track in handbrake so there wouldn't be any audio track.
7. I set the framerate to a constant 59.94 fps
8. I set the average bitrate to 451 kbps.
9. I then exported it to a new mp4.

Once done, I renamed this newly crafted mp4 to "battle_select_A2_1.mp4" and replaced the original subvideo.
I then finally tried encoding a THP with this new subvideo. (I left all the options for encoding set to default.)
FFmpeg opened and...

That can't be good...

This goes on for a while and even gets into the millions of frames so I pressed "q" to cancel it.

This is the properties for the first unedited subvideo "battle_select_A1_1.mp4":

This is the properties for the second edited subvideo "battle_select_A2_1.mp4":

I tried to keep them as similar as possible. I'm not sure what the issue is.

One more question... is "multiplicity" kind of like... the number of subvideos... inside subvideos?
I just started using this tool so it's a lot to take in...

I may initiate a pull request to fix some of the issues I have with the program myself if you're busy.

Let me know if you can help me out with my issue or answering my questions! ❤️

P.S. Can you please keep the deleting of temporary files to a minimum? Make it optional to delete them via checkbox?
My first time trying out the software I ran the encode on my desktop and there are a bunch of files on my desktop.
It definitely deleted some of my JPGs and possibly MP4s I had on my desktop.
Luckily I don't think any of them are too important to me but still...
Maybe add a warning to the user guide or something...
