When Should You Use POTM vs PPSX?

POTM vs PPSX: Key Differences

• •POTM and PPSX diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both POTM and PPSX use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: PPSX handles transparency.
• •File sizes: POTM files typically range N/A and PPSX files N/A.
• •Use case fit: POTM targets interactive presentations, automated slide generation and PPSX targets slide presentations, kiosk displays, automated demos — your choice depends on which workflow stage you are serving.
