PPTX at a glance
PPTX
Convert to PPTX when the output needs to remain an editable presentation.
It is the right target for sales decks, training materials, investor presentations, conference talks, board packs, and internal briefings where teams will rearrange slides, update branding, swap charts, or localize content later.
Use PPTX when presenter notes, slide masters, animations, and embedded media need to survive.
If the deck is finished and should not change, PDF is often better; PPTX is for ongoing presentation workflows.
3G2 at a glance
3G2
Convert to 3G2 when preserving compatibility with legacy CDMA handset recordings, telecom media archives, or workflows that explicitly expect 3GPP2-style mobile video.
It is useful for migration and recovery of old phone clips.
For current playback and sharing, MP4 is almost always the better destination.
