Final Output Adds Extra Seconds When Exporting at 29.97/59.97/23.98 fps in Premiere Pro

Hello Adobe Community,

I'm encountering an issue with Premiere Pro where my final video output is longer than the original timeline after exporting. Specifically, a video with a timeline duration of 00:39:21:18 ends up being 00:39:24:00 after export, despite setting the export frame rate to 29.97 fps. I've confirmed that both my sequence and export settings are consistent and set to 29.97 fps. This also applies to other footages and output of 23.98 & 59.97 Here are the details:

• Premiere Pro Version: Up to date (V. 24.2)
• Sequence Settings: 29.97 fps
• Export Settings: H.264, 29.97 fps
• Source Footage Frame Rate: 29.98

I've checked for frame rate consistency across my footage, sequence, and export settings. Additionally, I've verified that I'm using the latest version of Premiere Pro.

Could this discrepancy in the video length be related to a setting I might have overlooked, or is it a known issue with a workaround? Any insights or advice on how to ensure the exported video matches the original timeline duration exactly would be greatly appreciated.

Thank you in advance for your help!

Drop-frame or NDF ... non-drop-frame? That might be an issue for the 29.97 ...

Thanks for your comment! I've tried both Drop-frame and NDF through sequence settings, and still have the same issue here...

Having the same issue with 23.98 Adobe Premiere project. The export says the output will be 26:45...but then the film is 26:47. Did you find an answer to your issue?

Where exactly are you seeing the longer duration—inside Premiere or in an external player?

It's possible you're noticing a difference between drop-frame and non-drop-frame timecode. Some media players or metadata readers display durations using drop-frame timecode (especially at 29.97 or 59.94 fps), which can make the total runtime appear slightly longer.

To verify the true duration:

• Import the exported file back into Premiere Pro.
• Check the duration in the timeline or Program Monitor.

If the duration matches your original sequence, the export is correct—it's just a display difference based on timecode interpretation.
