Many videos from JuliaCon 2019 have quite long openings, when we can see only poster of this JuliaCon or watch preparation for the talk. Also they can have similarly long endings. Below you can see information about 20 from 117 talks on JuliaCon 2019 playlist and my suggestion about time boundaries to cut them. I hope that at the end of the week I will make such annotations to all talks from this JuliaCon.

I’m doing this because it is easier to wait with making timestamps until someone edit video, than adjusting them afterwards and I want to make timestamps to keynotes from this JuliaCon.

| Title of the talk | Starts at | Ends at | Length of the video |

This was previously in thread [Mistakes in the text on Julia YT channel](https://discourse.julialang.org/t/mistakes-in-the-text-on-julia-yt-channel/73166), but since is getting quite long I decided to put it in separate discussion.

Another 20 talks from JuliaCon 2019. I know that my proposition may be bad, but at least their are starting point. Some videos definitely need re-cutting.

With this portion we cover if not all, almost all videos from JuliaCon 2019. I probably missed few of them, but since when I wrote that I a bit tired, so errors are more probable to occur, and re-cutting already listed videos will be a lot of work, I will end here.

Maybe in few weeks I will go back to these problems.
