SOLVED! Rendering Suddenly Becomes Very Slow and then Errors in Premiere Pro

When trying to render or export a 30-minute project in Adobe Premiere Pro, the exporting process suddenly becomes very slow (around 3 hours or more), whereas usually, a 30-minute project only takes 30-40 minutes. This is the issue I encountered.

This is my experience

Initially, I received the error "Bad allocation while creating disk aligned video frame," and after clearing the memory (RAM), this error disappeared, but the rendering or exporting time remained unreasonably long. The estimated time remaining could be more than 3 hours, whereas normally it only takes 30-40 minutes.

In my case, it turned out the problem was with the video files I used (not RAM usage allocation). So I had to convert the problematic videos first, and after they were converted I could use them in Premiere Pro normally. After converting the videos, the issue of long rendering times disappeared, and rendering times returned to normal as usual.

For reference, the problematic videos were from an action camera with the "rotate camera" feature enabled. It seems this feature caused errors in the video data, falsely indicating that it has hundreds or even thousands of FPS, whereas the original frame rate was only set to 30 FPS. I always use footage from the same camera without the Rorate feature On and no problem when editing in Premiere Pro.

As explained above, this might be a very specific case where previously I often rendered or exported with a time frame of 30 to 40 minutes, but suddenly in this project, the export time significantly increased to more than 3 hours, with the same duration, effects usage, and type of editing. Sometimes the application suddenly stops before the export process is completed.

These are the steps I took, my problem was solved or fixed using the first method below but if you are still having problems after using the first method, I suggest you try the other methods below:

Convert the original video to a constant framerate.

  1. In Premiere Pro, if you're using more than one video, try exporting each video separately to determine the estimated rendering time. You don't need to wait until the export process is finished (you can cancel it once you know the real estimated time), just pay attention to the "Estimated time remaining."
  2. Identify the video source that has an unusually long export process (different from other videos).
  3. Next, you have to convert the suspected video using the Handbrake application (free). Download and install the Handbrake converter application from this official page.
  4. Drag and drop the video you want to convert into the Handbrake application.
  5. Before starting the conversion process, please choose the "Constant Framerate" setting in the Video menu. Once done, proceed with the conversion process by pressing the "Start Encode" button.

  6. After the conversion process is complete, replace the original video in the Premiere Pro application with the converted video above. Then try exporting it again and observe the difference in the "Estimated time remaining."

In my case, after converting the video as described above, the problem of long rendering and frequent errors disappeared. The rendering or export process returned to normal as usual. If this method doesn't work for you, it means the problem isn't with the video you're using, so please try the alternative methods below:

Enable GPU Acceleration:

  • In Adobe Premiere Pro, open the "File" menu.
  • Select "Project Settings" and then "General."
  • In the "Renderer" menu, make sure you select: "Mercury Playback Engine GPU Acceleration (CUDA)."

  • Click "OK" to save the settings. Please restart the Premiere Pro application for the system to implement the changes properly.

Enable Hardware Encoding:

  1. Open the Export page (CTRL+M).
  2. Open the "VIDEO" settings.
  3. Look for the "Encoding Settings" menu.
  4. Then, in the "Performance" settings, select "Hardware Encoding."

  5. Once done, proceed with the render or export process as usual.

Activate Graphics Preference specifically for the Adobe Premiere Pro application:

  • On your PC, click the "Start" button.
  • Type and search for "Graphics settings." Once found, open the settings page.
  • In the "Choose an app to set preference" section, click the "Browse" button.
  • Look for and select the "Adobe Premiere Pro.exe" application file in the installation folder. Example: Local Disk C / Program Files / Adobe / Adobe Premiere Pro (according to the version used). If there are no issues, the Adobe Premiere Pro application will appear on the preference page.
  • Click on the Adobe Premiere Pro application on the preference page and click the "Options" button to bring up the Graphics preference menu.
  • Select "High performance" marked with the type of external GPU (not onboard GPU) you're using on your PC.

  • Don't forget to click the "Save" button to save the settings.

Restart the application every time you make changes.

It's highly recommended to restart the application if you've made changes in the Premiere Pro settings. Sometimes, important changes like rendering system replacements require application restarts for the changes to take effect.

Hopefully, this article provides solutions for sudden rendering errors, slow rendering, and occasional crashes in Adobe Premiere Pro. If you have any questions, please leave them in the comments section below. Stay wise, keep trying, and good luck!
