If you are using Windows and your computer has a discrete graphics card, you can select it for exporting in ActivePresenter > Preferences > Miscellaneous > Video Encoder. This is usually faster than the default option (Windows Media Foundation).
I can’t find K4200 in the Video Encode GPU Support Matrix list from NVIDIA at: Video Encode and Decode GPU Support Matrix | NVIDIA Developer
Maybe this GPU doesn’t support H.264 encoding or its driver was not installed correctly.
Can you please share the log of ActivePresenter so we can investigate further? To view the log, click ActivePresenter > Preferences > Miscellaneous > View Log.
Thank you for researching the log.
The video encoder is updated to the latest NVIDIA driver for the device.
After update, the GPU was available to AP as an encoder choice, please see attached screen.
I haven’t tested yet but expect this is the solution and export performance will improve.
Thank you again.
