Information for Presenters at Marina Bay Sands

This information applies to presenters whose talks will be presented between Monday, October 13th and Saturday, October 18th at the Marina Bay Sands venue. If your talk is taking place on Sunday, October 12th at the NUS School of Computing, please wait for the NUS-specific information to be published on a separate page and refer to that.

We assume most presenters will be in-person. If you need to present remotely, see instructions below.

Information for All Presenters

  • Your conference registration is mandatory.

  • We strongly recommend the use of a 16:9 or 4:3 aspect ratio for your slides.

  • You should pace your talk carefully; time is of the essence and the program schedule will be strictly enforced.

  • You can find the length of your talk in the program. Please aim to keep your talk at least 3 minutes under the slot length to account for setup and questions.

  • You will be receiving a presenter questionnaire from your respective event organizers. It is imperative to complete this form as early as possible so that the AV Committee can properly plan for your talk. You will be able to indicate if you are giving an in-person or remote talk and other important logistics via this form.

Information for In-Person Presenters

  • You should bring your own device to present your slides. Please ensure your slides are available offline/accessible from a different device in case of any technical issues.

  • Your presentation device should support HDMI output. If it does not, you are responsible for bringing the appropriate adapter.

  • During the breaks throughout the conference, take time to familiarize yourself with the room, and ask the Student Volunteer present to test out your laptop/slides. Clarify any question you might have with the Student Volunteer or an AV Chair in the room.

  • Arrive at your session at least 15 minutes before it begins. Make your presence known to the session chair and student volunteers. During the break before your session starts, ensure that your presentation device is working, and your slides are accessible in order to avoid last minute difficulties.

Additional Details

  • During the conference, you will wear a badge/lanyard with your name on it. Please take this off before putting on a microphone!

  • If you have a handheld microphone, please speak into it closely.

  • If you use a Mac for presenting, your device has True Tone display technology. While your slides will look fine on the projector or display, they will have a yellow hue on the livestream and in the recording. Please remember to turn off TrueTone in your device settings to prevent this. You can refer to the following instructions:

  • Go to Display Settings:

  • Make sure TrueTone is turned off:

  • Similarly, if your device has a night light mode or blue light filter, please disable this during your talk to ensure your slides look correct in-person and on-stream.

Information for Remote Presenters

  • If you plan to present remotely, please obtain approval from your respective program chair as early as possible. Additionally, inform the AV Committee of your plans via the presenter questionnaire mentioned above.

  • Remote presenters will interact with session chairs and in-person participants via a Discord video call. This interaction includes both the talk and the live Q&A.

  • While we also support playing pre-recorded talks, we strongly encourage remote presenters to deliver their talk live over Discord, so that the talk and Q&A take place over the same medium.

  • If your talk is remote, it must have the Remote or Recorded badge in the program. Otherwise, please notify your event’s organizers to add it for you.

Pre-Recorded Remote Talks

Some presenters may opt to submit a pre-recorded talk to avoid technical difficulties (e.g., unreliable internet connection, poor video call quality) or overcome timezone differences. Note that you will still be expected to participate in live Q&A over Discord after we play your pre-recorded talk, unless you have made other arrangements with your event organizers.

Following are instructions for preparing and submitting your pre-recorded talk:

  1. Prepare your talk as a video recording:

    • There are various tools available to record your talk. One of the easiest ways is to use Zoom: share your screen, unmute your microphone, and record your “meeting”. You can use tools like iMovie or ActivePresenter to edit your recording.

    • Make sure your video does not exceed your time limit. Your time limit is the duration of your time slot (as it appears in the program) shortened by at least 5 minutes, to allow for Q&A and switching to the next speaker.

    • Please submit a mp4 formatted video.

    • Your video file should be named according to the following schema: <EVENT_ACRONYM>-<SPEAKER_LASTNAME>-<TITLE_NO_SPACES>.mp4, e.g., PLMW-Cook-ResearchandDevelopment.mp4.

  2. Upload your pre-recorded talk to a cloud file-sharing service such as Google Drive. Do not share your video using YouTube or Vimeo.

  3. Submit your talk to the AV Committee:

  • Please submit your recording at least 7 days before the conference begins to avoid last-minute issues. If you have a last minute change and suddenly need to switch to a pre-recorded remote talk, the following instructions still apply, but please notify the AV Committee at sigplan-av+icfplash25@googlegroups.com.

  • When filling out the presenter questionnaire, indicate in the “Remote Talk Logistics” section that you will be pre-recording your talk. If you have already submitted the questionnaire, please edit your response (do not make a new one) to indicate that you will be delivering a pre-recorded talk.

  • Once you have done this, there will be a link to another form, both in the “Remote Talk Logistics” section and at the end of the questionnaire, which you can use to submit the link to your pre-recorded talk.

Recording Quality

To ensure a successful presentation, it is crucial that your recording is of high quality, especially the audio. The AV team cannot fix poor-quality recordings, so it is essential to record it properly.

We encourage you to check the quality of your recording before uploading it, ensuring that it is clear and understandable. Here are some tips to avoid problems while recording:

  1. Avoid the use of a laptop’s built-in microphone for recording.

  2. Avoid reverberant spaces, record in an environment that does not amplify echoes or reverb to keep the audio clear.

  3. Keep the microphone at an appropriate distance from your mouth during recording to achieve a crisp and natural sound.

Live Remote Talks

Setting up Discord

  1. Create a Discord account if you do not already have one. If you created a new account, please verify your email address.

  2. You will receive an invitation link to the Discord server via the email provided during registration. This will direct you to join the ICFP/SPLASH 2025 Discord server.

  3. After joining the server, you should be prompted with a Customization Question prompt.

    1. Select the Presenter role.

    2. Go to Channels and Roles located at the top-left of the server sidebar.

    3. Follow the Test Sessions, category.

  4. You now have access to all the required Presenter channels.

Live Remote Talk / Q&A-only

Please join the Test Sessions (1/2) voice channel (whichever one has fewer users at that time) at least 40 minutes before your presentation – see the instructions below for more information. The same applies to Q&A-only presenters who have a pre-recorded talk.

After the test session, you will be given access to a unique voice channel with the title of your talk at the top of the server’s channel-list. Feel free to turn your camera on and screen share in preparation for your talk.

For Q&A-only presenters, we suggest you join your corresponding talk-voice channel while your pre-recorded video plays. You may mute yourself to prevent making noise over the video.

You can follow the live stream of current talks on the ACM SIGPLAN YouTube channel: https://youtube.com/@acmsigplan.

Test Sessions

To attend a remote test session, please join the Test Sessions (1/2) voice channel at least two talks before yours – ~40 minutes before your talk. A volunteer will be there to assist you in preparing for your presentation (in the case there is no volunteer, please contact the AV Committee.) If your talk will consist of multiple presenters, please make sure all presenters join a test session.

Here are some of the key aspects we aim to test:

  • Microphone quality (you might have to turn off certain settings to sound clearer or louder)

  • Camera quality and/or angle

  • Screen sharing quality

  • Internet connectivity

Each test session is imperative to guarantee the smoothness of your talk and is required. If you cannot join us for a test session the day of your talk, please email the AV Committee at sigplan-av+icfplash25@googlegroups.com with a proposed time slot so we can proceed. However, we encourage presenters to join for a test session shortly before their talk to prevent any changes between the test and the talk itself.

We suggest that all presenters have Direct Message permissions enabled for an ease in communication.
