Does it mean that you found your error with the "echo" technique?

of curiosity, how would you go about batch converting multiple .mp4 files

For basic cases, like all files are in the same directory, I would do
something similar to what you did: let the shell interpretor list the
files, iterate on them and build the command line by substituting parts
with loop variable. I would probably add quotes to prevent from files with
space to break the command and a "basename" subcommand to remove the
extension of the iteration name.

For more complex cases, it is to study case by case, but I would probably
start by listing the file paths in a text file and iterate on the lines to
apply similar technique.
