Instructions for Presenters

If you are a presenter, please follow the instructions as given below. If you have a question, please ask it on the #talk-preparation channel on the ICFP Discord (invite link).

In-Person Presenters

If you plan to present in-person please make sure of the following things:

• The preferred way to present is for presenters to bring their own laptops and have slides available offline.
• The aspect ratio of the slides should be 16:9.
• Please make sure your device supports HDMI output or that you have the appropriate adapter.
• Please check that your device works before your session starts so that we do not have any last moment hiccups.
• By default we assume (and strongly encourage) an in-person talk presentation. If the talk is to be delivered virtually please contact the organizing chairs and video chair as soon as possible.

Talk length

You should plan the length of your talk carefully, as time is precious and the schedule will be strictly enforced. To find out the length of your talk, find it in the program and subtract at least 5 minutes from the time shown there, in order to allow for questions and switching between speakers.

Specifically, for the main ICFP program talk slots are 30 minutes and speakers should aim to give a 25 minute talk; the remaining time is for set-up (around 1 minute) and questions (around 4 minutes).

Giving the talk

Please arrive at your session meeting room at least 10 minutes before the start of your session. Take time to familiarize yourself with the room setup, meet your session chair, and address any issues with the student volunteers.

Virtual Presenters

If you plan to use the virtual option, please get a pre-approval from the organizing chairs of your track, and inform the video chairs as soon as possible.

Testing for Live Virtual Presenters

• You can use a test zoom room to test our audio/video and screen sharing with the help of a volunteer.
• Please arrange for a test session by messaging on discord channel #talk-preparation

Technical requirements for pre-recorded talks

• Screen ratio should be 16:9.
• Videos: please compress your videos. Supported formats are MPGs, WMVs, or with the following AVI codecs: H.264, MPEG-4 (Divx, Xvid, or WMVs), Indeo, Cinepack, Techsmith.

Recording your talk

There are various tools available to record your talk, the easiest way is to use Zoom:

1. Start a meeting
2. Share your screen and enable your webcam and microphone
3. Start recording your meeting locally and start your talk.
4. After your talk, stop recording.

You can use tools like iMovie or ActivePresenter to edit your recording. After editing, save the video file in MP4 file format. Please make sure the audio quality of the recording is good with minimal background noise and upload it to google drive for sharing with the conference organizers.

Video Sharing Instructions

1. Make sure the video length does not exceed the allowed time limit. We will not be able to use it otherwise. The time limit for your talk is your time slot, as given in the program, shortened by at least 5 minutes, to allow for questions and answers, and switching to the next speaker.
2. Name the video file using the following scheme: <EVENT-ACRONYM>-<Speaker-lastname>-<TitleWithoutSpaces>.mp4, e.g. PLMW-Swamy-FStarAwesome.mp4.
3. Upload your video on a cloud file sharing software, such as Google Drive.
4. Email video chairs (apoorv-ingle@uiowa.edu, j-hui@cs.columbia.edu, and gjespada@ciencias.ulisboa.pt), and the organizing chair of your event
   1. Link to the recorded video file which can be downloaded. Sharing YouTube/Vemeo link is not acceptable.
   2. Explicit consent stating that you agree the talk video to be used in the conference and be uploaded on the SIGPLAN YouTube channel.
