Premiere Pro 2025 – Hardware Encoding Export Error on Long & heavy Projects

Hi, my name is Haris Ahmed, and I’ve been working in video editing, animation, and graphic design for the past 2 years. Recently, after switching to Premiere Pro 2025, I started facing a major issue. Whenever I try to export a long project with hardware encoding, the export fails and gives an error every time. If I switch to software encoding, the export works, but it takes a lot of extra time, which slows down my workflow. I’m using a system with an 8GB dedicated GPU, so hardware encoding should normally work without a problem.

As you can also see from the image I posted, my projects are usually long and heavy, so this issue is making the workflow very difficult. I’ve already tried multiple solutions and troubleshooting methods, but the problem is still there. Can anyone guide me on how to fix this, or let me know if this is a known issue in the 2025 version? Any help would be greatly appreciated.

    What specifically is your hardware, and Premiere version, in number-dot-number format. Such as 25.4.0. "Latest" is pretty much useless.

     

    Your heavy projects ... are they long, or going to large file size codecs? As Premiere requires 4-5 times the expected file size, of open free space on the drive you are exporting to, in order to complete the export.

     

    So if you're expecting say a 1.5GB export file, you need at least 7GB, if not 7.5GB, of free space on that drive.

     

    Next, some effects combinations can cause fails of large exports. So sometimes, with complicated sequences, it is better (and far faster!) to duplicate the sequence (rename for sanity's sake) ... then on the dupe, use the "simplify sequence" option ... then export.

     

    Warp can also cause this at times, so I do recommend (as a practical thing only) to always do a render & replace on any clip with Warp applied ... so that when the playback and eventual export are going on, things just proceed vastly faster. And with less chance of dorking on you.

    Everyone's mileage always varies ...

    I’m currently on the latest version of Premiere Pro 2025.
    As for disk space, I already have around 55GB free on the export drive, so
    that shouldn’t be the issue.

    Regarding Warp Stabilizer, I’ve never used it in any of my projects.
    Instead, I often work with the Horse Composer plugin, and my edits are
    usually quite heavy.

    About the third suggestion, I’ll definitely try duplicating the sequence
    and using the Simplify Sequence option to see if that makes a difference.
