A snippet of bash code i threw together to help myself. It doesnt do all the work, but it does most. It is not perfect, but it saved me hours of renaming, and the metadata came in after.
Look up the seasons on TheTVDB, put them all into their own temp folders.
Then you can run the script on the folder.
You tell the script the season, how far in to the file name ("_" as the split) to place the season (and episode offset if needed). It will then go through the folder adding in SXXEXX to the files.
It will replace spaces with _ so you dont have to worry.
So if you ran the script on a folder with:
[GROUP]_Anime_Name_123_[Numbers].mp4
[GROUP]_Anime_Name_124_[Numbers].mp4
[GROUP]_Anime_Name_125_[Numbers].mp4
[GROUP]_Anime_Name_126_[Numbers].mp4
with
aniname 11 3 4
It would change the files to
[GROUP]_Anime_Name_S11E04_123_[Numbers].mp4
[GROUP]_Anime_Name_S11E05_124_[Numbers].mp4
[GROUP]_Anime_Name_S11E06_125_[Numbers].mp4
[GROUP]_Anime_Name_S11E07_126_[Numbers].mp4
NOTE:
If there are double episodes, you will have to break there, do those separate, then run again with the offset.
If some files have a different number of "leading name chunks" before the drop point, you will have to do those separate as well
