Timewarp (What's New in 2025.2)

CPU Support (Rocky Linux)

On Rocky Linux, an inference can be run using either the CPU or GPU. The only option available on macOS is still CPU.

Running the inference is faster on the GPU, but larger frames that cannot be rendered using it can now be rendered using the CPU.

Use the CPU / GPU drop-down button to select the mode of your choice. The ML Engine Cache button is only available when GPU is selected.

Bit Depth Support (Rocky Linux)

On Rocky Linux, when using the GPU rendering platform, the choice to run a model in 16-bit fp or 32-bit fp is offered. In previous versions, models were only run at 32-bit fp.

Selecting 16-bit fp offers the following advantages:

  • It allows running a model on higher resolution images, since running in 16-bit fp requires less memory.
  • It provides better performance.

Workflow

For the Machine Learning Frame interpolation, the playback and scrubbing of unrendered frames is now more interactive in the Timeline environment due to the Player option available in the Timeline FX Timewarp Preferences. By default, the option is set for scrubbing and playback to use the Mix frame interpolation at 0.0 instead of the Machine Learning Frame interpolation.

The options are:

Select To
Result on Scrub / Play Always display the result of the Timewarp node.
Mix on Scrub Display the result of a Mix frame interpolation instead of the result of a Machine Learning frame interpolation while scrubbing in a clip.
Mix on Play Display the result of a Mix frame interpolation instead of the result of a Machine Learning frame interpolation while playing back a clip.
Mix on Scrub / Play Display the result of a Mix frame interpolation while scrubbing or playing back a clip.
Note: When one of Mix on Scrub, Mix on Play, or Mix on Scrub / Play is selected, frames are not rendered while scrubbing or playing back even if the Player's Cache on Playback option is enabled.
