When After Effects export fails, do not change all settings at once. Examine the error log, output path, and problematic time interval in order.
Save the current state first
Note the error message, application version, output format, and the time the process stopped. Work on a copy of the project; keep the first file. The log file described in Adobe's rendering documentation is the starting point for investigating why the render did not complete. Since not every error occurs for the same reason, do not consider a single setting on an old forum as a universal solution.
Simplify the output path
Check that you can write to the destination folder and that there is enough free space. If you are using a network or sync folder, try a short printout in a local, accessible folder for diagnosis. Do not confuse cache space with final output space. Just because the file is created does not mean it is complete; Further verify that it is playable and of the expected length.
Reproduce the problem in a small range
If the process always stops at the same point, test that area as a short output. Examine the relevant layers, effects, and source images one by one on the copy project. Change only one variable in each attempt and record the result. This way, when a solution is found, you know which change is effective. Check Adobe documentation for compatibility of source media and output format with the version used.
Close by rechecking the delivery
After the printout is complete, watch the beginning, the end, and the problem area. Audio, frame rate, duration and transparency, if any, must match the delivery need. Save the successful settings in the project note; If reproduction will be required on another computer, also specify the dependencies used. Storing the working file, preview, and publication file separately makes subsequent revisions easier.
Convert error note to support request
When escalating the problem to someone else, write down the application and operating system version, the output method used, the error message, and the result of the short test. The sentence "It doesn't render" is not enough to reproduce the problem. Check required permissions and confidential information before sharing customer media; If possible, prepare a small example showing the same error.
Adobe's render and export document is the starting source for the save file and output options. Don't assume that a particular folder name will solve all rendering errors. After the successful attempt, open not only the preview in the program but also the exported file. Guide to delivering large design files completes the hassle-free output reaching the recipient with the correct version.
Frequently asked questions
What should I save first in case of After Effects render error?
Note the error message, the time interval in which it stopped, the output settings, and the version used. Narrowing down the problem by running on a copy of the project and changing a single variable is more tractable than randomly changing all the settings.
Can the video be delivered directly if the rendering is complete?
Completion alone is not enough. Open the printout thoroughly and check for missing frames, wrong duration, audio and video compatibility; Verify that the file plays in the target environment.
