How to save stream blendshape

[kimtomato]

I am using it as an app(mac_version), how can I save blendshape stream data?

and is it possible to extract blendshape from pre-recorded video using Phiz?

At this moment Phiz only outputs data live and you can save the data externally.
Saving text data as csv/json might be a function in the future but it's low priority for now.

Extracting blendshapes from pre-recorded videos is actively being developed right now.
