If you:
-
are using Clipchamp on a Mac
-
are importing video files taken on an iPhone
and see the message: Converting your assets for use, this might take a while, it's likely that these videos were recorded on your iPhone (or iPad) in the HEVC format (also known as H.265).
In most cases, HEVC videos can get handled by Clipchamp without converting them first. However, if you notice that your video is slow to import, you can try converting it and then use the resulting MP4 video file in Clipchamp instead.
If HEVC videos are synced to a Mac via iCloud Photo syncing, then exporting from the Photos app on the Mac will automatically convert the videos to the H.264 format. This is the format Clipchamp works with, and clips will import quickly.
However, videos will stay in HEVC format if they are transferred to your Mac by:
-
the Files app on iOS, then reading them from the iCloud Drive folder on your Mac.
-
AirDrop
-
iCloud Photo syncing but imported directly from the Media/Movies folder in the file open dialog (i.e., not exported from Photos)
Suggested workaround
To get your videos to load more quickly when you add them to a Clipchamp project, export them from the Photos app on your Mac. This will automatically convert them. Then, import the new file version into Clipchamp.
The steps are simple:
-
drag the videos into Photos.
-
drag them back out - you can drag them back to the same folder, and they will get a new file name.
When you drag HEVC videos out of Photos, they will be converted to H.264 automatically. The files will be slightly larger but will import into Clipchamp faster than their HEVC counterparts.
