I've had issues exporting my animation, resulting in Adobe Animate crashing. Turns out, Animate makes a temporary video before it sends it to Media Encoder. Depending on your Animation's length, framerate, and resolution, this temporary video can be 10's or even 100's of gigabytes!
Furthermore, there is no built in option to set this temporary video location other than your system drive. System drives with inadaquate space will result in Animate having problems, including crashing.
Luckily, there's a solution to this on MacOS, which is similar to the solution for Windows using a symbolic link. A symbolic link, or symlink, allows you to create a file that points to another directory, even on another drive. Since Animate's temporary folder lives on the system drive, we can make a symlink to it on another drive, and Animate will never know the difference.
Just be aware before you start, you are about to alter an important path on your file system and write data to an external drive, and it's up to you to make backups of your project and tempory folder. You are solely responsible for the risk taken to perform this.
The safeguards and steps to take are:
1. If Animate is open, save if needed, and quit.
2. Make a backup of your project.
3. Open Finder, and navigate to /Users/Username/Library/Application Support/Adobe/Animate 2022/en_US/Configuration and rename the folder named "tmp" to "tmpOld". The "en_US" folder may be different depending on your language settings. This is a quick and easy way to make a backup of your system's tmp folder in case something goes wrong.
4. Open an additional Finder window, and navigate to the drive you would like Animate to write the tempoary video to, and create a folder named "AdobeTmp". Inside that folder, create a folder named "tmp". This will be where Animate will write the data to.
5. Open Terminal. In Terminal, you're about to write a command that will create the symlink from your system drive to the external drive. Keep both Finder windows open: Your system drive inside the "Configuration" folder, and the "tmp" folder on your external drive, to check if the command performed correctly.
6. In Terminal, without pressing enter, type "ln -s". Then you will need to write your new external tmp folder's location, and then your system drive's Configuration folder's location.
The easiest, and most fool-proof way of doing this, is to drag those folders one at a time, right onto the Terminals command prompt in the order I just specified, and it will automatically write out the paths. The command should appear something like this in the end:
ln -s /Volumes/AdobeTmp/tmp /Users/Username/Library/Application\ Support/Adobe/Animate\ 2022/en_US/Configuration
7. Press enter on your keyboard to run it. If it simply went to the next prompt without errors, or any other message, that's good news.
8. Check your system's Configuration folder. It should now have a new folder named "tmp" with a black arrow.
9. Open Animate, and export your video by going to File >> Export >> Export Video/Media, and enter whatever criteria you need to render your Animation, and click Export.
10. Check the Finder window with the external tmp folder that you created (NOT your system drive's folder!). If everything was done correctly, your tempoary video should appear in under 20 seconds.
And that's it. Media Encoder should open after the video finishes writing, which will result in a much, much smaller encoded video.
