Delete the Media Cache
This is the easiest and most effective solution for this problem so we're starting with it.
- Restart Premiere Pro and do not open any new projects.
- Next, click on Edit > Preferences > Media Cache, and click on Delete under Media Cache Files. You’ll see two options; choose the last one.
- Choose Delete all media cache, then click Ok and Premiere Pro will restart.
Once you have done this check the hardware settings Premiere Pro is trying to use.
Check the Encoder & Decoder Premiere Pro is using.
This method will use software to export the project. Just be aware that this is super slow so a big project may take days not minutes.
- Click on File > Project Settings > General.
Here change the setting next to Renderer:
- If you have an Nvidia GPU, choose "CUDA."
- For Intel or AMD GPUs, select the corresponding option.
- If available, choose "OpenCL" for other GPU types.
Note: Opt for any option that mentions GPU acceleration if you see one. This will give you the fastest export speeds possible.
If you are desperate, you can use Mercury Playback Engine Software Only but it will be a super slow export process.
- Apply Changes: Click "OK" to save the settings.
Still see Timeline Sections Appearing in Red?
If any section of your timeline remains red, it may indicate intensive effects that require pre-rendering for smooth playback.
- Navigate to the red section.

Review your timeline to ensure all sections are properly rendered and playback is smooth.
