Montage Help CenterWhy a file is still getting ready
Every file goes through two steps before Montage can use it: Upload, then Prepare. Here is what each one means, and what to do when a file is stuck.

| Its row says | What is happening | Can you leave the page? |
|---|---|---|
| 1. Upload · 1.2 of 4.8 GB · 25% | Your file is going up from your computer or phone | No. Keep the page open while it uploads |
| 2. Prepare · you can leave · Preparing · 37% | Montage makes the small file to watch, a full-quality copy, its picture, and listens to the words spoken in it | Yes. It goes on without you |
| Ready | The file can be used | — |
In Media, a file on its way says Getting ready.
If you already pressed Make my video
The button says Waiting for your footage…, and under it: « Montage starts by itself as soon as your footage is ready. » You can leave once every file is uploaded.
When a file does not get ready
| Its row says | What to do |
|---|---|
| Upload stopped at 42% · the connection dropped, nothing is lost | Press Resume |
| This video didn’t finish uploading | Add it again |
| The upload was cut. Drop the file again. | The page was closed during the upload: drop the file again |
| Can’t be opened · This file is damaged or isn’t a video | Try another copy of the file |
| Not added · your space is full | Delete footage you no longer need, then add it again |
Stuck on Preparing for a long time? Press Contact support, bottom left (in the menu on a phone), with the file’s name.
Questions
Why does Montage prepare my file at all?
So it plays the same in every browser and phone, whatever the camera made: the right way up, in normal colours, with its words heard.
Does preparing use my credits?
No. Credits only pay for the AI’s work on your videos.
Can I start describing while it prepares?
Yes. Write your description and press Make my video: Montage waits for your footage, then starts.
