AD-NeRF/data_util/deepspeech_features/deepspeech_features.py

Line 158 in 9fdcd7e

deepspeech_fps = 50

Your video's fps is 25 Hz rather than 50Hz, so the feature may be not aligned with the video.

And also the length of the output features is not equal to that of video frames. 'Make window' action is not right.
