video length changed
frankenstein91 opened this issue · comments
Hello I have run one of my videos through the program over several days to make faces unrecognizable. I have already expected that there will also be false detections. These I wanted to overlay with the original video, because in my opinion it should be the same video only with faces pixelated.
Unfortunately, I noticed today after several days that the source movie and destination movie are no longer the same length.
The word Laufzeit is German for playback length. I am currently trying to adjust the frame rate of the two videos.

Sorry for the late reply. Have you managed to solve this issue? I don't have any idea why the result has a different frame rate (30.015008 FPS
vs. 30.020000 FPS). The frame rate of the original video is read from its metadata and is used to render the resulting video (see https://github.com/ORB-HD/deface/blob/4fd379c5/deface/deface.py#L130).
no, issue is still there. only found a workaround
