Annoying rendering bug in VEGAS Pro 23..

1. offizieller Beitrag

    Everytime i export with vegas pro 23 it pushes over to 5 HOURS! so i tried voukoder out, and it fails everytime while saying this in the logs: 2026-08-21 14:52:29 (info) [EncoderNode.cpp:440] Opening video encoder plugin 'h264_nvenc' with params '{"rc":"constqp","qp":23,"g":12,"bf":0}'
    2026-08-21 14:52:29 (error) [EncoderNode.cpp:449] Opening the encoder plugin failed with error code: -542398533
    2026-08-21 14:52:29 (error) [Router.cpp:194] Open phase failed: -11
    2026-08-21 14:52:29 (info) [VoukoderPro.cpp:690] Unable to open a Voukoder Pro session. Please check the log file.

    if i change to microsofts h264 encoder it renders fine, but really slow im guessing because its using my cpu.

    NVIDIA RTX 3060 12 GB Vram

    Ryzen 5 5500

    16GB Ram

    Windows 11 Pro

    Thanks, that was helpful!

    A few things for you to check:

    1. Restart the machine (clears GPU state)
    2. Check your driver version (nvidia-smi) — make sure it's ≥ 560 for NVENC SDK 13.1
    3. If it persists after reboot, update to the latest Game Ready or Studio driver
    4. Run nvidia-smi -q and check for "ECC Errors" or "XID Errors" in the output

    Looks like there isn't any errors at all! restart didnt help either. Can it be because im on Driver Version : 610.88 [Deprecated; will be removed in CUDA 14.0. Use KMD Version instead]
    CUDA Version : 13.3 [Deprecated; will be removed in CUDA 14.0. Use CUDA UMD Version instead]
    KMD Version : 610.88
    CUDA UMD Version : 13.3
    and not 560?

    also voukoder worked once and thats when i found out that the output node was a thing and it worked. but now with the same configurations it doesnt work.

    Also another thing to note is when rendering the video on VEGAS Pro it DOES NOT use my gpu, even gpu acceleration is on and stuff. So maybe my gpu is just not being used at all with rendering

    No, the minimal driver version must be met. Any higher driver version is alright.

    2026-08-21 17:11:28 (trace) [FFmpeg:0] dl_fn->cuda_dl->cuCtxCreate(&ctx->cu_context_internal, 0, cu_device) failed
    2026-08-21 17:11:28 (trace) [FFmpeg:0] -> CUDA_ERROR_ILLEGAL_ADDRESS: an illegal memory access was encountered

    I'm wondering if maybe your GPU is defective. That would explain this error (and it is also not used by VEGAS Pro).

    I haven't seen this before.

    My GPU cannot be defective. All the games use my gpu fine, After Effects 2024 Renders fine (not 2025 n newer because they ruined the gpu usage with the rendering). I haven't seen this either, im guessing its just stupid Windows 11 problems or my drivers are corrupted. Im gonna try to install the Studio Drivers instead in NVIDIA App.

    That didn't work either. and once again the microsoft h264 export works fine, but uses my cpu which is slow

    Alright guys, i think i solved it. I COMPLETELY reinstalled FFmpeg because last time i did it there were some components that werent deleted. im not sure if it works but it worked this time.
