Wow! Now everything is normal!
I checked all the formats and codecs at 25fps in project settings and render settings.
Source video also 25fps (from camera and youtube).
Thank you Justin for hot fix!
Thanks you James for thorough testing!
There is one more question - a little shifted sound after render with different encoders. See attachment.
It is not very important, because most commonly used AVC (H.264 / AAC). But anyway. And apparently, this shift feature FFMPEG?
P.S. The option in render settings to replace the original audio in a video file without transcoding all the same it would be great to have!
