If an upload is refused because it is too large, the file is over the space left on your plan, or over a single-file limit. Here is how to get it in.
Free up space
Each plan includes a set amount of storage. If you are near the limit, remove videos you no longer need, or download and then delete older ones to make room.
Move to a larger plan
If you regularly run out of space, a higher tier gives you more storage. See Change or cancel your plan.
Trim the video first
A shorter clip is a smaller file. If you only need part of a recording, trim it down before uploading so it fits.
Check the file
A single very large file can exceed the per-upload limit even when you have space. Trimming the recording into the part you actually need usually brings it under the limit.
