@simsimdaour I just heard this about one video recently about 2 weeks back. I believe this is possible if that audio portion is really hard to transcribe so instead of having a very low confidence transcription, the section may be skipped. However, without seeing the video, it's hard to confirm. I have been working with the user who provided that feedback to see if we can get a copy of that video for debugging. Would you be able to share couple of the videos from your end with me and the transcription tech team I work with?
