Here are some suggestions for what to do if your video doesn't export or exports too slowly from Clipchamp.
Suggested steps that can help solve export issues
Avoid surfing in other browser tabs or windows while exporting – if you navigate to a different window or tab, your browser can de-prioritise the processing for other open pages, and thus the export may run more slowly or stop.
Make sure Chrome or Edge are updated to their latest version. If not, update it. The following shows the steps for Chrome, those for Edge are very similar:
Clear your browser cache (in the "clear browsing data" menu choose "All time" and "Cached images and files"). Make sure you still have your original files (the video, audio and image files you added to your project) as you may need to relink them when you reopen the video.
Restart Chrome (or Edge if you're using this browser)
If the above steps don't help, here are some additional suggestions you can try:
Close other browser tabs or windows.
Shut down other applications on your computer.
Avoid running in incognito mode (if you have opened an incognito window and are accessing Clipchamp in it, you are running in incognito mode).
Try temporarily disabling some or all browser extensions.
Check for an update for the graphics card driver of your computer. If you're on a Mac, this means checking your Mac system software is up to date. If you're on a Chromebook, this means checking your Chrome Operating System is up to date. If you're on a PC, you can check for and download driver updates from your graphic card manufacturer's site, e.g. Intel, NVIDIA, AMD.
If none of these suggestions help: The Chrome team has disabled some graphics card drivers as they can make Chrome unstable or even lead to a crash, therefore we generally don't recommend to make a change to this setting however at your own risk you can also try the following: go to chrome://flags/#ignore-gpu-blacklist in a new browser tab and enable this flag, which will allow all graphics (GPU) drivers to be used. Be aware that this might lead to Chrome becoming unstable.
Other reasons for export failure and possible solutions
The most common reasons a video can still fail to export are:
it is too long (e.g. more than 10 mins) for the computer you're using to be able to handle the processing
the input files are too large for the computer you're using to be able to handle the processing (e.g. 4K files)
one or some of the input files are corrupted
If you have access to a different computer with a different CPU and graphics card and more memory available, you can try opening and exporting your video on it instead. NOTE: to do this you must bring your input files with you, please see working on a video on a different computer.
You can also try compressing any large video files you are using in the project and then adding the resulting compressed MP4 files instead. We particularly recommend this when working with 4K files, since Clipchamp doesn't support exports in 4K yet (only 1080p), so the resolution is going to be reduced when exporting anyway.
Alternatively, you can try breaking up a longer video into several shorter ones and see if that enables you to export. You can do this by creating a copy of a video on the Dashboard page, then going in and deleting a part of it and attempting to export what remains.
If you don't mind sharing your input files with our support team, we can analyse a video that's failing to export to try and determine what the problem is and fix it. If you'd like to do this, please get in touch with us through the chat icon in the bottom right. Note that at certain times of the day or on weekends it may take some time to receive a response due to time zone differences and our office hours.
