Background presentations will take place in weeks 8 and 9. We strongly recommend that you pre-record your presentation. We will send you instructions on how to upload your video file to us in the future. However, if you prefer, you can also live stream your presentation.

The presentation should be 15 minutes long.

Q&A session of 5-10 minutes will follow right after the presentation. Please make sure at least one of you is available for the entire 25 minute slot.

We would like each member of the group to be part of the presentation.

Shortly after, you will receive feedback from us regarding the content of your presentation, as well as some general feedback on the form. This feedback should help you give even better presentations: for your own project presentation in final weeks of the semester, as well as in the future.

Please understand the paper as well as you can (ask us questions if anything is unclear). Then, choose the aspects of the material that you liked, understood well, and you believe are important.

Here are some useful resources on how to prepare and give talks:

• How To Speak by Patrick Winston
• How to give a great research talk by Simon Peyton Jones

Please do not use Viktor's videos as a model for the presentation, but instead incorporate as many points of the talk of Patrick Winston as you believe apply to your presentation. It is an amazing and entertaining talk, despite (or because) it is meta-circular: he does as he says. Note: breaking physical objects or referring to supernatural beings in your video is not required. Use your own judgement and strike a balance in being comfortable with what and how you are saying things and trying out these pieces of advice.

We suggest that the speaker's video shows up when the speaker starts to speak, so that the audience can relate and identify the speaker. Afterwards, the video can be turned off and should come back on for questions and answers. Optionally, a small video can stay on throughout the presentation. The main content of the presentation should be a window showing the material being presented, for example as a PDF to which you can point to and/or annotate it. If the hardware allows you, you can also use a tablet to simulate a blackboard presentation where you write down everything you present, or use a combination or simple slides and a strategy of what you will write on them.

Video upload: please upload your video to this channel (login with EPFL credentials)

For your information and not as a requirement, Viktor's lectures are prepared using this hardware and software setup on Ubuntu 20 OS:

• slides prepared using the `beamer` latex package
• slides annotated using `xournal` PDF annotator in full screen mode on display size 1920×1080
• recording using Zoom, with the following options:
  • screen sharing PDF annotator (`xournal`), without option to optimize for full-screen viewing
  • local recording, with option Optimize for 3rd party video editor
• wacom cintiq pro display as external monitor for annotating PDF's using pen
• video segments are cut and assembled using ffmpeg, which works very fast:
  • cut like this:

fmpeg -i zoom_0.mp4 -ss 00:00:00 -to 00:02:03.00 -c copy mysegment01.mp4

• concatenate like this:

ffmpeg -f concat -i segmentlist.txt -c copy mycombinedvideo.mp4

where segmentlist.txt is a file containing one line per each file to include:

file 'mysegment01.mp4'
file 'mysegment02.mp4'
file 'mysegment03.mp4'
