Montage Help CenterFiles Montage can read
Drop your files as they come off your phone or camera: Montage takes videos, music, pictures, and a few other files, and prepares each one itself.

What Montage does with a video
You never convert anything first. Montage prepares every video the same way, whatever it was:
- It stays at its own size.
- HDR footage (an iPhone’s default) is turned into normal colours for watching.
- It is turned upright, the way the phone was held.
- Its sound is made stereo. A surround track is mixed down to two channels.
Your original is kept as it is. Where your originals are kept.
When a file can’t be read
If even Montage cannot open a file, its row says Can’t be opened: « This file is damaged or isn’t a video ». In Media it says « This video couldn’t be read. Try another copy of this video. » Press Try again, or Contact support: we see the file’s name.
Questions
Can I add ProRes or camera files?
Yes. ProRes MOV, MXF and MTS files go in as they are, and Montage prepares them.
I added the same file twice. Does it take twice the space?
No. The same file (same name, same size) brought again is the one you already have: nothing is sent, and its row says « from your media ».
Can I add a PDF or a Word file?
No. Only the files in the table above.
