Introduction · Advanced user tips Hardware » Nvidia® CUDA™ H.264 Encoder

If your graphics card supports the Nvidia® CUDA™, you will be able to enhance the recording ability of Bandicam by using the GPU of the graphics card. Bandicam 1.9.0 or a higher version supports the Nvidia CUDA H.264 encoder, so Bandicam users can record the target in high speed, with a high compression ratio, and in high quality.


How to use the Nvidia CUDA H.264 encoder

1. NVIDIA doesn't support the CUDA H.264 encoder from the GeForce 340.43 beta driver.

To use the CUDA H.264 encoder, download cuda_enc_windows7_8_64bit.zip and copy&paste the nvcuvenc.dll file to the designated folder. (C:\Windows\System32\nvcuvenc.dll and C:\Windows\SysWOW64\nvcuvenc.dll)

2. Choose the "H.264 (Nvidia® CUDA™)" option from Bandicam

- Click the Settings button under the Video tab of Bandicam, then choose the "H.264 (Nvidia® CUDA™)" encoder.
- H.264 (Nvidia® CUDA™) is one of the most commonly used formats for the recording, compression, and distribution of high definition video. (View the comparison of video codecs of Bandicam)
Nvidia CUDA H.264 encoder Settings
  •  1   VBR (Variable bitrate) - Quality-based: VBR allows a higher bitrate for faster scenes and a lower bitrate for slower scenes, as a result, the recorded video size can be made smaller. (Recommended)
  •  2   CBR (Constant Bitrate) - Bitrate-based: CBR always uses the same bitrate, as a result, you can predict the video file size (But, the recorded video size might be larger.)
  •  3   GPU+CPU (Recommended): This option allows you to use both CPU and GPU (Graphics card).
  •  4   Only GPU: If you have a faster GPU (and slower CPU), try this option.
  •  5   GPU device: If you use more than 2 GPUs, try this option. (For example, use graphic card A for recording and graphic card B for gaming.)
  •  6   FourCC code: To play the recorded video on media players, choose "H264". To edit the recorded video with Sony Vegas, Adobe Premiere with the AVI container, choose "X264".
  •  7   Keyframe interval: If you choose "150" as the Keyframe interval, keyframes will be created every 150 frames.

NVIDIA removed the nvcuvenc.dll file from the GeForce 340.43 beta driver.

1) If you use Windows 7/8 (64bit), download cuda_enc_windows7_8_64bit.zip and copy&paste the nvcuvenc.dll file to the designated folder. (C:\Windows\System32\nvcuvenc.dll and C:\Windows\SysWOW64\nvcuvenc.dll)

2) If you use Windows 7/8 (32bit), download cuda_enc_windows7_8_32bit.zip and copy&paste the nvcuvenc.dll file to the designated folder. (C:\Windows\System32\nvcuvenc.dll)

If you use GTX 600 series or higher graphics cards, please use the Nvidia NVENC H264 encoder.
