Tiny clip taking over 2 hours to export?

[jesse_6198]

I am new to Premiere Pro.  Used to use Sony Vegas, and switched recently. I am trying to export like a 30 second clip from a larger video, and it's taking over 2.5 hours for the encoding. Here is the file info I copied from premiere:

File Path: D:\RECORDINGS\2025-09-20 10-10-44.mkv
Type: Matroska
File Size: 93.74 GB
Image Size: 1920 x 1080
Frame Rate: 60.00
Total Duration: 08:20:18:41
Pixel Aspect Ratio: 1.0
Alpha: None
Color Space: Rec. 709
Color Space Override: Off
Input LUT: None

As well as some additional file info from VLC:

What needs to be changed here for this to work significantly better? This is only a tiny clip, and soon I'm going to be working with much longer exports that also involve 4k video from my camera.

Here's my specs as well:

Processor AMD Ryzen 9 3900X 12-Core Processor 3.79 GHz
Installed RAM 31.9 GB
Graphics Card NVIDIA GeForce RTX 2080 SUPER (8 GB)
System Type 64-bit operating system, x64-based processor

Your file is 93 GB !!! and over 8 hours.

That will take a long time to export, even though the timeline contains a short section of the clip. 

Dont know if this is going to speed things up but try a subclip or render and replace.

Render and replace and then exporting the clip worked. Thanks. Will need to work on my obs settings to get smaller file sizes

Hi jesse_6198,

Welcome to the community! Is this happening with that specific source media or with other media as well? Also, do you have sufficient storage space on your drive & have you applied any effects to the clip in the timeline? We're here to help, just need more info.

Thanks,

Sumeet
