When 'Frame grouping' is selected in the interface, the system allocates a sequence of frames to a render node, instead of a single frame at a time. Activating this feature can significantly decrease the render time (and costs) for projects under certain circumstances. We recommend activating this option in two specific cases:
1. When the project has very short frames (under two minutes per frame).
2. When the project is very complex and has a very long load time (the stage before starting the render)
The number of frames in a group should be set depending on the render time per frame. For very fast frames (2-3 seconds per frame), the group size can be set up to 50 frames. For longer frames (up to 2 minutes per frame), we recommend a maximum of 10 frames per group. For longer projects (over 5 minutes per frame), we recommend a maximum of 3 frames per group. Setting a too large number of frames in a group can negatively impact the delivery time in case of errors or crashes at the 3D software level.
