here’s a different approach, using RECONNECTING
have one sequence with one entire film on it.
stack different audio versions in the audio tracks,
add new audio as it comes in.
for each new language just solo that language track,
and EXPORT a reference movie.
reference movies are small files and quick to make
append the language and give it a .ref so you know it’s a reference movie
to swap out one language for another,
copy the sequence into a new project,
select all, reconnect, and navigate to the new language’s ref movie.
if each feature is one file, then you should be able to do a reconnect for each movie in one go.
smal problem is the NAME of the clip wont change with the reconnect.
so..
once you have reconected,
select the sequnce in the browser, then Tools Menu > Create Master Clips.
right click on the clip/s in the browser, and choose Modify Clip Name to File Name.
