What is the best way to convert data from continuous visual stimuli into BIDS?

Dear everyone,

I apologize if this is a duplicate, but I couldn’t find an answer.
I have a visual behavioral experiment that dynamically presents stimuli in a long, continuous fashion, making each frame valuable information. What’s the best way to convert this data into BIDS keeping the relationship between stimuli and participants’ behavior? Intuitively, the physio approach seems to be the best option. If physio were the best approach, I assume I should still use physio as a suffix instead of beh, correct?
Thanks in advance for any suggestions.

Cheers,
Emanuele
