1. Slow Performance or Application Crashes

2. Missing H.264 Error

3. Expression Errors

4. Render Issues or Glitches

5. RAM Preview Issues

So, if you have ever struggled with any of these issues, keep reading to find out how to solve them.

Slow Performance or Crashes

Like most top-end video editing software, Premiere Pro and After Effects require significant computing power. So, if your PC is lagging or crashing when you run After Effects, you can narrow the issue down to being a PC performance issue. Your PC might be unable to cope with what After Effects takes to run.

A few reasons why your PC could be struggling to run After Effects are:

• Out-of-date software

• A full cache

• Low RAM

To resolve these issues, try updating your software, clearing your cache, and increasing your RAM. Changing to an SSD would also significantly speed up your PC if you’re using an HDD drive. This should prevent After Effects from crashing or slowing down and help you render faster. Here are the Specs Adobe suggests you should meet for After Effects to run well:

Minimum Specifications

• Quad-Core processor

• 16GB of Ram

• Windows 10 (64-bit) or Mac Big Sur or later

Recommended Specifications

• 8-Core or above for Multi-Frame Rendering recommended

• Windows 10 (64-bit) or Mac Big Sur or later

• 32GB of RAM

If After Effects is crashing while rendering, this is often linked to insufficient RAM or outdated software, which could be fixed by increasing your system’s resources or updating your software. Similarly, if After Effects crashes when opening, this could indicate a corrupted file or hardware issue, often resolved by clearing the cache or updating drivers. If your local hardware isn’t meeting the requirements, consider using After Effects on a cloud computer to access more powerful resources without upgrading your PC.

Missing H.264 Error

Another common issue is finding the H.264 codec missing when you want to export. The H.264 codec allows you to use the Adobe Media Encoder User Interface with its background encoding system without leaving AE.

H.264 is a tool that video editors use to compress videos for online use while maintaining quality. Here’s where the issue arises from the two standard rendering methods in AE. People choose “Add to Adobe Media Encoder Queue” or “Add to Render Queue.”

If you choose “Add to Render Queue”, which seems like the most obvious choice when you want to render, you will have limited resolutions. However, if you choose “Add to Adobe Media Encoder Queue”, the H.264 export option will be listed. If the H.264 export option in After Effects is missing, switching from the Render Queue to the Adobe Media Encoder Queue should help you find it.

Expression Errors

Expression errors are common in After Effects and can disrupt your workflow. Expressions are small JavaScript codes used in After Effects to evaluate or add a single value to a layer property at a specific point on your edit.

Some causes of expression errors include:

• Incorrectly written expressions

• Referencing no-existing layers

• Using incompatible syntax.

An After Effects expression error is usually caused by syntax mistakes or incorrect references, but switching to Legacy ExtendScript may resolve the issue. To do this, go to Project Settings > Expressions, click the drop-down menu, and change JavaScript to Legacy ExtendScript.

Apart from this, reviewing your Expressions to ensure they are all correct is the best way to avoid further errors.

Render Issues or Glitches

There’s nothing worse than putting in hours of effort to produce a video and, once it’s rendered, finding that rending errors or glitches are present. While frustrating, it is common and can have various causes. Here are a few of them:

• Plugins or effects that are not functioning correctly

• Incorrect rendering settings

• Corrupted source files

So, to get to the cause of our rendering issue, we need to troubleshoot. That means checking effects and plugins. By turning off your effects and plugins one by one, you can use the process of elimination to find the issue.

Triple-checking your rendering settings can also help you avoid this from happening. Check that your resolution, frame rate, and output format match your intended specifications. Checking if your source file is damaged will be pretty simple; If your After Effects file is damaged, the software will often label it as Error 33:7. Another common issue is After Effects rendered video lagging, which can happen if your rendering settings or frame rate are not optimized for playback.

After Effects backs up your edits automatically if set to do so. Check if AE has an older version of your edit before it was corrupted and load that. If you haven’t activated this setting, try this:

• Step 1: Save a backup of the corrupted AE project.

• Step 2: Open a new project in AE.

• Step 3: Import compositions from the corrupted project.

• Step 4: Bring in relevant assets like images and videos.

• Step 5: Manually recreate animations and effects if needed.

• Step 6: Copy and paste accessible keyframes.

• Step 7: Rebuild complex elements with salvaged assets.

• Step 8: Consider professional data recovery or Adobe Support.

If you cannot retrieve your corrupted content, then using a template might help you recreate it faster.

When After Effects is taking forever to render, reducing the resolution or using more optimized effects might speed up the process. Troubleshooting by turning off plugins one by one and checking your rendering settings (resolution, frame rate, output format) can often resolve the issue.

RAM Preview Issues

Getting a preview of your work during the editing process in After Effects is essential before rendering. When a video editor previews their content in After Effects, it creates a temporary video file or RAM cache file. Unfortunately, that cache folder can fill up quickly, and many of us forget about it.

As a result, your preview may glitch or lag as you try to watch it. Other issues that can influence RAM preview errors are when you add complex effects and compositions to your edit or if your preview settings are too high. Here’s how you can solve this problem:

• Go to Edit>Purge>All Memory to clear your cache.

• Go to Preferences>Memory & Multiprocessing and increase the RAM allocation given to After Effects.

• Choose a lower resolution for previews.

• Turn off specific effects and compositions while you preview your work.

How to Fix Missing Effects in After Effects

Missing effects in After Effects can happen if plugins or presets aren’t installed or have been removed. To fix missing effects in After Effects, ensure all necessary plugins are installed, or reset preferences to refresh the available effects.

How to Increase Video Quality in After Effects

To increase video quality in After Effects, adjust your rendering settings, such as resolution and bitrate. Using high-quality export codecs like ProRes or tweaking compression settings can also improve the visual quality of your rendered videos.

After Effects Handles Missing

In case your After Effects handles are missing when adjusting layers, this might be a settings issue. Check if your View Options are set correctly and ensure handles are enabled in the interface settings.
