Is it possible to edit a youtube video this way?

Question

YouTube

Some time ago a video was uploaded to youtube.
You need to edit it by deleting in two places for 4 seconds of the video.
According to the manual, this can be done on the youtube site itself.
It remains to clarify the following:
- The video will be cut, respectively, and the audio track too. This means that in the cut off places the sound will abruptly break off. Therefore, you need to replace the audio track with another one (where the sound will not break off).
The official youtube manual says that the audio track can be changed, but the text of the instruction itself only talks about tracks (music).
Is it possible to change the entire audio track in a youtube video? (that is, not only music, but the entire audio track)
and
- Is it possible to somehow replace the video on youtube, while maintaining the number of views, comments, etc.? (if editing will be done not on the youtube site itself)

Answer 1

1) no, because the video is evaluated and accepted by the system as a whole.
This is due to the technical features of YouTube as a service.
You can only change the sound overlay, the sound of the video itself simply cannot be changed, it will be ANOTHER video.
2) no, since the video has a link, it is accepted and processed, and then it is ranked and checked by YouTube bots / algorithms. Even unpublished ones.
In general, different content is different content.
Otherwise, if you imagine, how much drugs, porn, pedophilia and other garbage and rubbish could be!
Therefore, neither technically nor legally - one does not change to another.

Answer 2

Is it possible to change the entire audio track in a youtube video? (that is, not only music, but the entire audio track)?
Can.
Now it can be done:
In the old editor, you can cut out part of the video. In the new editor, I had difficulty with this. In addition, in the new editor, when trying to trim part of the video (in a 15-minute video), the system displayed a message that long videos cannot be trimmed. Perhaps this will be fixed in the future.
As for the video, when replacing the audio track (in the old editor), it offers options for overlaying "new music". There it either overwrites the old one, or overwrites only individual pieces that you yourself choose.
I have not yet tried to overwrite the audio track in the new editor. I do not rule out that certain difficulties may arise there.
