export of mp4 file fails

I wanted to export a 3 hour video with Adobe Premiere Pro 2023 (v23.4.0).

In the past I didn't had issues with it.

This are the settings I render my videos with:.

Format H.


Code settings Hardware-acceleration.

HDR-graphic 203 (75% HLG, 58% PQ).

Bitrate settings CBR with 50Mbit/s.

At first it failed with error code 39.

After research on the matter I deleted the cache in PP and tried exporting again.

Now the software finishes the task but with warning:.

– File encoded with warning message .

– XMP data could not be written to output file .

I can open the mp4 video but it like crashes after 20min.

Same result after reboot.

Does anyone of you had a similar issue or knows how to fix it?

Question from user FireLady_Jess at premiere at reddit.

The error code 39 you encountered in Adobe Premiere Pro 2023 indicates an issue with the export process. Deleting the cache was a good troubleshooting step, but it seems you're still facing some problems with the exported video.

The warning message you received regarding XMP data not being written to the output file suggests that there may be an issue with the metadata associated with the video. XMP data is typically used to store information about the video, such as markers, tags, and other metadata.

To address this issue and potentially fix the crashing problem, you can try the following steps:

  1. Update Adobe Premiere Pro: Make sure you are running the latest version of Adobe Premiere Pro. Sometimes, software updates can address known issues and improve stability.

  2. Change export settings: Try adjusting your export settings to see if it resolves the problem. Instead of using hardware acceleration, try disabling it and see if the export completes successfully. You can also experiment with different formats and codecs to see if that makes a difference.

  3. Disable GPU acceleration: If the issue persists, you can try disabling GPU acceleration altogether. To do this, go to “File” > “Project Settings” > “General” and uncheck the “Enable accelerated Intel H.264 decoding” option. Then try exporting the video again.

  4. Export in segments: If exporting the entire 3-hour video at once continues to cause issues, you can try exporting it in smaller segments. Export multiple shorter segments and then combine them using a video editing tool or video player.

  5. Contact Adobe support: If none of the above steps resolve the problem, it would be best to reach out to Adobe support directly. They can provide further assistance and troubleshoot the issue specific to your setup and software version.

Remember to always keep backups of your project files and footage before making any significant changes or troubleshooting steps.
