Opening steps
Choose your environment or purpose to see its steps.
Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- Missing playback may involve separately linked media; ask for the complete source set.
- Check font substitution for moved text. Screenshots cannot validate animations.
- Only video fails: determine whether it is embedded or linked and obtain linked media.
- Macro requirement: distinguish viewing from automation; plain PPTX will not preserve VBA macros.
- Legacy appearance changes: compare compatibility mode, fonts and shape effects in the source and converted copy.
PPT → PPTX
- Use Save As → PPTX in PowerPoint under a new name.
- Compare the two slideshows, including media and timing.
- Reopen the saved copy and check presenter notes, linked assets and playback sequence.
Review warnings for legacy objects/macros. PDF is for static pages, not a substitute for animations/audio.
Legacy PPT macros and conversion
PPT is a legacy binary format; its suffix does not establish whether macros exist. Confirm a suitable macro-capable destination when preservation is required.
Review presenter notes and the slide show after editing; the editing view alone can hide playback differences.

Pre-presentation checks
On the actual device, test fonts, aspect ratio, sound, video and click order; prepare a static PDF if useful.
Check linked video and online resources before presenting without internet access.

Questions and answers
Why is a video missing?
A linked media file may be missing. Request the original presentation set.
Does PDF preserve animations?
Ordinary slide PDFs are static. Validate the slideshow separately.
Can I just rename PPT to PPTX?
No. Save through a compatible presentation application.
Can I rename PPT to PPTX?
The internal formats differ. Open it and choose the output format in an application.
