The file produced by Recosoft is built as if it was natively constructed in Powerpoint. It may need some tuning in powerpoint which is no issue, but building a 70 slide presentation with a limited interface, limited graphical capabilities, and a lack of customization seems counter intuitive when you use Adobe products day in and day out.

Recosoft allows me to set up everything I need in a much more designer friendly way in InDesign, and with the click of a button create a perfectly editable and converted powerpoint file. PDF from InDesign exported to PowerPoint only gives you an exceptionally rough starting point. And trying to create PowerPoint presentation masters from PDF? Uggh! InDesign supports Type 1 fonts but not so Microsoft (starting with Office 2013 on Windows). Except for some raster images, Microsoft is RGB only ( implied sRGB). InDesign supports full ICC color management including CMYK and RGB of different flavours.

InDesign supports 16 transparency blending modes (including multiply which is what normally should be used for drop shadows) while Microsoft only supports the equivalent of the Adobe normal blending mode (you can't even get a decent drop shadow). InDesign supports a much richer imaging model than Microsoft Office. It is totally unrealistic either through PDF to PowerPoint conversion or otherwise! Why?

On the other hand, I don't expect to be able to convert these presentations to PowerPoint. It is the only way I can deal with placement of graphic objects, advanced graphic attributes, advanced typographical features, reliable layout (that doesn't change based on the phase of the moon and the resolution of the currently selected printer), and full access to paragraph and text styles. Actually, I use InDesign for 100% of my presentations.
