Questions about evaluation

[quqixun]

FF++ and DFDC are applied to do evaluation.

[1] For FF++, there are 1000 videos in 500 pairs. For each video, 10 frames are evenly sampled, composing 10K frames test set. Thus, there are 5K paires frames in total to perform Hififace infrence, generating 5K swapped faces. Metrics about ID, pose and shape are computed based on 5K swapped faces. Dows this description right? Which compression degree of videos in FF++ was applied to compute relative metrics? Raw, c23 or c40?

[2] DFDC containes four parts, such as preview, train, validation and test. Which part of DFDC should be used to compute relative metrics?

[3] According to the FPS in Table 1, more than 25 rounds can be performed per second. What steps are included in one round?
