Audio and Video

Adding Audio

Insert → Audio → Audio on My PC. Tune on the Playback tab: Start (Automatically/On Click), Loop until Stopped, and note the volume icon needs visible controls on the slide.

Adding Video

Insert → Video → This Device (file) or Online Video (YouTube/OneDrive link). Video plays within the slide during the show.

Controlling Playback

• Start - Automatically, On Click, or In Click Sequence.
• Full Screen - plays the video filling the screen; bookmarks Mark In/Out.
• Trim Video and Fade In/Out (Playback → Trim Video / Fade Duration).
• Poster Frame - choose a still frame shown before play.

Embedded vs Linked Video

• Embedded files travel inside the .pptx but grow the file size quickly.
• Linked files keep the deck small but the video must be sent alongside.
• Online videos need an internet connection during the presentation.

Multimedia Health Check

• Test the video on the actual projector machine beforehand - codecs differ.
• Keep clips short; 30-90 seconds engages, minutes puts the room to sleep.
• Add captions/alt text to video for accessibility needs.

Key Points

• Videos and audio are inserted, tuned and trimmed from the Playback tab.
• Match Start timing to how you deliver (click vs auto).
• Test multimedia on the target machine - do not discover codecs at showtime.
