CX Aortic 2021 Presentation Guidelines

Discussion time at CX is extremely important and we fiercely protect the five minutes of discussion and Q&A after each talk.

As a result it should be noted that presentations exceeding five minutes will be sent back for editing.

This is non-negotiable, so please check the length before submitting your slides

To facilitate consistency and to ensure readability of slides, please observe the following guidance:

  • Please download the template below
  • If you do not use the template provided, please ensure the slides are formatted for a 16:9 ratio screen (not 4:3), as per the template
  • Add your institution logo to the bottom-right of the first slide
  • The CX Aortic logo must remain on the bottom-left of the slide, as per the template
  • Use the default blue font for text on all slides, as per the template. This will ensure content can be read easily against the blue background
  • If an additional colour is needed alongside the blue, think about the other colour fonts and ensure they’re not too hard to read against the blue background
  • Avoid decreasing the font size below 24 as it will be too hard to read

Recording Your Presentation

First, check your microphone is working in Windows Settings > System > Sound > Input > Test your microphone

We strongly recommend using an external microphone or the microphone of a headset for the recording rather than a computer’s built-in microphone. This minimises external noises which will be coming through when the built-in microphone is used.

Open your Presentation in PowerPoint then follow the steps below, or watch this step-by-step video guide to recording audio. Be aware that if you choose to record video for your presentation (rather than just audio), please do not site in front of a light source otherwise your face will be in silhouette.

  1. Select Slide Show > Record Slide Show
  2. Record from the Beginning
  3. When you’re ready, select Record and start speaking
  4. Narration won’t record when slide transitions happen so let these play first before you start speaking

Save Your Presentation

  1. To create the video, close the recording window and select File > Export > Create a Video
  2. Important: Ensure the default Presentation Quality values of Full HD (1920 x 1080), and Use Recorded Timings and Narrations are selected
  3. Click Create Video
  4. Enter the filename as ‘First name Last name – 1 (the number applies if you have more than one talk)
  5. Save as Type ‘MPEG-4 Video’
  6. The recording will be saved in the background, progress is shown at the bottom of the PowerPoint window
  7. Playback the new .mp4 file and ensure the presentation is how you want it

Manage narration and timings

There are different ways to manage recordings in your presentation:

  • Pause – to pause a recording
  • Stop – to end a recording
  • Replay – to replay a recording
  • Pen, Highlighter, or Eraser – use the pen, highlighter, or eraser tools to mark up your recording

Remove narration or timings

An audio icon appears on a slide when narration’s available.

You can also remove narration or timings from your slide.

  1. If you’re in record mode, select Clear.
  2. Choose from two options:
    • Clear Recording on Current Slide – to delete narration and timings on the current slide
    • Clear Recording on All Slides – to delete narration and timings from all slides at once

Submit your presentation

Before submitting, please check the following:

  • Make sure that your presentation does not breach any data protection laws and that any patient names or identifiable information is obscured.
  • Check the presentation does not exceed five minutes – if it does, you will need to edit it until it is 5:00 minutes max. We recommend between 4:50 and 5:00.
  • Ensure the file is saved in presentation quality 1920 x 1080
  • Check it is saved as a MPEG-4 Video file
  • Check the name of your file follows the format ‘First name Last name – 1’ (the numbers will apply if you have more than one talk) Example: Joe Bloggs – 2

Please make a final check of your file to check the audio is how you would like it and it corresponds to the correct slides within your presentation(s). Please submit the PowerPoint AND the video file.

We will contact you if we notice any issues or if it is too long/short.

Speaker & Moderator Rehearsals

We appreciate that virtual meetings come with technical challenges you may not be used to. To make the process as easy as possible, we offer rehearsal time for speakers. If you cannot attend a rehearsal, you will find the video below useful.


Moderator rehearsals will be available for those who did not already moderate at CX in April and we will be in touch directly. Please email [email protected] if you have any questions about this.
