Rendering the final 360 VR video

Process panel

To render the 360 video output file, simply switch to the process panel :


  1. Set the output file name. Using the ‘browse’ button.
  2. Review important project settings : Blender, video start and end time and output size. The maximum button will attempt to compute the maximum size.
  3. Then decide how you want to process the video:
    1.  Hit ‘Process Now’ to start rendering the video immediately. You can decide to render on one or multiple CUDA GPUs.
    2. ‘Send to batch‘ adds the project to the batch stitcher queue. ‘Send a copy of the project’ is an option to duplicate and save the project with a different name, which will be sent to the batch queue. Your current project will remain opened in VideoStitch so that you can further edit it.
  4. Set the desired video encoding parameters.
  5. Select the soundtrack that should be copied from one input video to the output
  6. Set the projection type and Horizontal Fov values for the output video. If you used an external calibration tool, it is recommended to change the projection and output FOV directly in it.
Changing the fps value will affect the length and playback speed of the output video. It is not compatible with audio as we do not provide audio resampling yet. It is recommended to keep the same framerate as the original video.


Encoding settings

  • Large panoramic videos and fast motion video content require a higher bitrate
  • It is highly recommended to use output sizes that are multiples of 16. eg: 1920×960, 3840×1920, 4096×2048, 4800×2400, 5120×2560
  • To encode your output video specifically for web and mobile devices, please check-out this blog post:


Video codecs

H264: this is the default encoding. It is supported by most softwares and provides the best compression / file size  compromise. Maximum resolution = 4096 pixels.

MPEG4: Mpeg4 part2 (not AVC) encoded video. Output size must be a multiple of 8. Maximum resolution = 8192 pixels.

MPEG2: widely supported by video players, it provides an acceptable quality at the price of a high bitrate. Doesn’t support resolutions that are multiple of 4096. (eg. 4096px, 8192px). Very high resolution videos (over 8192 pixels) won’t be decoded properly by most video players and editing suite at such high resolution videos are not common in the industry yet.

Exporting very high resolution sequences

Video encoding for very high resolution output can be problematic :

  • when the maximum available bitrate is insufficient for the output resolution’s needs.
  • when your video editing suite doesn’t decode properly very high resolution videos (Most video players won’t handle properly videos over 8k).

In such situation, you may want to fall back to an image sequence export, such as *.jpg, or *.tiff
