Put a video in a presentation without it failing
The classic: the video plays on your laptop and not on the room machine. Usually it is the format — an .mkv, an unusual codec, or a clip shot sideways on a phone. The fix is to convert it to 16:9 MP4 first and embed it already converted.
Step by step
- Run the clip through the Video Converter: you get a 16:9 MP4, which any PowerPoint plays.
- If the video is going to be a slide of its own, upload it with the rest in Slide Merger and put it in place.
- Download the .pptx and open it on the machine you will present from, to check it beforehand.
Why it usually breaks
- The format. PowerPoint plays MP4 (H.264) everywhere; .mkv, .avi or .mov depend on the machine and the codec.
- The aspect ratio. A vertical or 4:3 clip gets black bars or is cropped on the projector. Converting to 16:9 removes the surprise.
- The size. An unconverted phone video can make the file too big to email.
- The broken link. Insert the video as a link instead of embedding it and it vanishes on another computer.
Frequently asked questions
Can it play automatically on that slide?
Yes: the video is embedded with autoplay, so it starts when you reach its slide.
Does converting lose quality?
It is re-encoded, so a little. For a projector you will not notice; for cinema, keep the original.
What about a vertical video?
It is centred inside the 16:9 frame with black sides. That is the right call: cropping would cut off people’s heads.
