Best Practices to Render Videos

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.

Reduce video render time

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 will require encoding in a video editing software. WebM takes significantly longer to render but the output file will be smaller due to encoding. 

WebM or image sequence, be patient, rendering the first frame always takes the longest. 

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

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

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, but also the render time.  

When setting the VRAM usage, be mindful of your dedicated 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. If you encounter strange artifacts in the rendered video, reduce the VRAM usage. 

Keep in mind that when using x-ray view some point loading is normal, as the entire depth of the dataset needs to 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, then 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), make sure that all of them have the same FPS setting. Different FPS settings can lead to choppy videos. 

For video editing, we suggest using Adobe Premiere Pro.
