PPSX at a glance
PPSX
Convert to PPSX when the deck should behave like a presentation on open, such as self-running briefings, classroom slide packs, customer demos, or event displays.
It is appropriate when the content remains PowerPoint-native but the primary user action is playback rather than editing.
If users are expected to revise the deck, PPTX is usually the better target.
MKV at a glance
MKV
Convert to MKV when you need multiple tracks, subtitle support, chaptering, or less common codec combinations in a single container.
It is ideal for archival masters, media-library organisation, multilingual releases, and technical video handoff.
For mainstream web playback and easiest consumer sharing, MP4 is usually simpler.
