How to optimize video render quality & time

Optimize video quality

Prevent blurriness

Video encoding algorithms always struggle with point clouds. Make sure to choose the appropriate material settings, especially the size parameter, and avoid hectic camera paths.

Minimize tiling effect

The VRAM usage determines the number of points rendered in each frame. The higher the VRAM usage, the more points will be rendered, ultimately increasing the quality and the render time.  

When setting the VRAM usage, be mindful of your video memory. The default is set to 4 GB, but depending on your system, you can choose higher settings to decrease the perception of point loading. 

Remember that some point loading is normal when using the x-ray view, as the entire depth of the dataset must be rendered to simulate the x-ray view.

Use image sequence for video editing

If you plan to add your logo to a video or combine a video with other footage, render an image sequence. You can then import this image sequence into your preferred video editing software.

Working with an image sequence will preserve quality by avoiding repeated compression.

When combining multiple video footages (from NUBIGON and third party), ensure they all have the same FPS setting. Different FPS settings can lead to choppy videos. 

For video editing, we suggest using Adobe Premiere Pro.

Optimize video render time

Render image sequences rather than WEBM

To reduce video render time, pick an image sequence format instead of WebM. 

Rendering an image sequence is three times faster than WebM but will produce larger output files and require encoding in video editing software. WebM takes significantly longer to render, but encoding will make the output file smaller. 

Be patient with WebM or image sequence; rendering the first frame takes the longest. 

Do not render WebM in 4K (it’s WebM, not us)

Rendering 4K to WEBM can max out CPU usage, prolong render time, and trigger crashes. We recommend rendering image sequences instead if you prefer to produce content in 4K.
