How to convert GC .vid(Divx) movie file to .sfd?

[Redistrer]

I extracted GameCube games with dolphin and got MovieDivxPlayer.tgc MovieSfdPlayer.tgc.
So, I extracted these files again and found a .vid(MovieDivxPlayer.tgc) and .sfd(MovieSfdPlayer.tgc) files which seem to be movie files.
I was able to convert SFD files with vgmtoolbox, but I can't convert .vid files.
I think VID files are Divx movie.(MovieDivxPlayer)
Does anyone know how to convert these files?

sample VID file : https://mega.nz/file/LbYDRaIB#SuJ5OUbFT ... goVqCcMZX4
sample SFD file : https://mega.nz/file/fTxWRAjC#PsLDl9N5V ... mDIB6H4zw4

I don't know if it works for your specific file, but whenever I had files that I was unable to convert to .sfd, I used ffmpeg to convert them to mpeg1 first and then I was able to use that file with sfdmux (it worked much better than Sega Dreamcast Movie Creator for me) to convert it to sfd.

Try using ffmpeg like this:
ffmpeg -i input.vid -b:v 3000K output.m1v
Hopefully it'll do the job.

Thank you for replying.
I tried your instruction, but ffmpeg said "input.vid: Invalid data found when processing input".
I'm no longer working on this issue as I can play it with Dolphin.
If anyone knows something, please use this place.
Thank you.
