Thanks for the comments.

I'm suspecting the issue of arc not working properly may be because I have several other programs that also have the arc.exe included. So when I attempt to run the arc command, the command may be selecting another location of arc.exe and not the arc.exe within the Freearc directory.

Presently trying to remove paths to the other programs containing arc.exe and see how things go. And trying to run arc.exe from the current working directory of Freearc\bin.

EDIT: I managed to get Arc.exe working with methods by copying Arc.exe and Arc.ini and srep to the current working directory which contained the test mp4 file.

The initial problem of Arc not working properly was most likely due to the presence of multiple copies of Arc.exe and Arc.ini within several other programs which were causing conflicts with each other.

EDIT2: Did some compression tests on 70 MP4 files ranging in size from 547 kB to 11,351 kB.

NOTE: for compression options using lm4 for files, files fail to decompress! Do not use lm4 option!

There is not a great difference in final compressed file sizes regardless of compression method.

Not really the best ideal final compressed sizes, but MP4 files are difficult to compress.
