BUG: Media Encoder fails at timestamp 00:00:00 (Selector: 9 Error Code: 3) for very long project

After editing a 12h01m long project and trying to render it, after 5 hours of processing Media Encoder reports an error and fails to encode the mp4 file.

This is the error that I get in the logs:

 

------------------------------------------------------------
 - Encoding Time: 04:57:40
06/09/2024 02:23:39 AM : Encoding Failed
------------------------------------------------------------
A low-level exception occurred in: H.264 (Exporter:9)

Export Error
Error compiling movie.

Export Error

A low-level exception occurred.

Writing with exporter: H.264
Writing to file: D:\main.mp4
Around timecode: 00:00:00:00
Component: H.264 of type Exporter
Selector: 9
Error code: 3

------------------------------------------------------------

 


I noticed that the timecode is 00:00:00:00, so I ran a test and rendered only the first 30 seconds of the project instead of rendering all 12 hours. Media Encoder rendered everything, and the exported video was fine. So there's nothing wrong with the project at the timecode of 00:00:00:00.

So why is Media Encoder reporting this problem at this timecode then?
What does the "Selector: 9 Error Code: 3" mean?

After finishing my on-going projects I did eventually update from Adobe Premiere Pro v22.3.1 (Build 2) to v24.5.0 (Build 57), and the problem no longer occurs. After the update I did need to convert my ".prproj" file for the new version to be able to open the project, but after rendering the video I had no issues. It seems that updating did solve this issue in the end.

I started creating a 13h timeline and the render got stuck on Win11 when I turn "Import sequences natively" on. I will file a bug on this.

BTW I forgot to mention my specs; I'm running on Windows 10. CPU is an i7 7700K, GPU is a GTX 1080 Ti.

I will test again soon after moving my media cache.

I just transcoded a 14 hour MPEG-2 timeline to HEVC using Adobe Premiere Pro 24.4.1.2 and Adobe Media Encoder 24.4.1.2 within 2 hours on a MacBook Pro 16" (2021, M1 Max). I used an external USB drive with 1 TB of free space and put the project and media onto this disk and as well the media cache files. Will try the same on Windows 11.

Can you also try moving your media cache files to those volumes?

There were no other errors in the log other than the 00:00:00:00 timestamp I posted in the OP, which happens at the end of rendering.

The target file was being rendered to an empty drive with 1.8TB of free space.
The source files were being read from another drive with 13.2TB of free space.

Let me know of any other information I can provide to help track down this issue.

Does the enocder log show anything else (e.g. other errors) in the case of the 12h video? How much disk space have you left? Please note that there will be additional disk space needed to create temp files, e.g. for muxing. I will try to create a simple 12h timeline for testing.

Hi and thanks for the replies!

 

Important new information about this problem:
LENGHT was the cause of this bug all along. Adobe Premiere Pro and Media Encoder are not able to render a 12h video for some reason, but they are fine rendering two 6 hour videos (tested with ZERO changes to editing), which you can later join using ffmpeg's "concatenate" feature through the command line.

 

More details:
- if I render the 12h01m project directly with Adobe Premiere Pro, exactly the same error occurs. So it's not specific to Adobe Media Encoder.
- I tried using Adobe Media Encoder again, and after rendering 7 of the 12h I pressed the "stop" button. On my output folder the video was rendered absolutely fine with no errors or problems, and I could watch all 7 hours of it.
- Afterwards I used Premiere's "Work Area" feature to render only the 5 hours that were left. Everything rendered just fine. Then I used ffmpeg's "concatenate" to join both videos, and I got the 12h video that I needed.
So I solved the problem on my end but it would be nice if this was fixed on Adobe's end so other people don't run into this issue in the future when doing very long edits.

 

Adobe Premiere Pro v22.3.1 (Build 2)
Adobe Media Encoder v22.3.1 (Build 2)
(Yes I know these are outdated but I didn't want to update in the middle of editing big projects, another of which is still on-going...)

 

I'm using H.264 software encoding (CPU); here are the export options I used:

Yes, I can share the project file with you, but not the source videos because those are over 80GB in size. However, I can't find any option to upload attachments in this website... how can I share the project with you exactly?

Hi @Coincident ,

Sorry for the problem. Can you please share some details like AME version number, device/OS details, and media files present in the project?  Please try the same workflow in the Beta builds also and let us know how it goes. 

As Ecki requested, it would be good if you could share the project to help us reproduce the issue in-house. 

Thanks,
Mayjain
