Part 2: Convert Slideshow to Video in More formats Offline

It should be noted that online slideshow to video converter apps could only process one conversion at a time. This means that if you have multiple slideshows, you have to wait for one conversion over before you start to convert another slideshow to video. This makes it very inconvenient. Meanwhile, online slideshow to video converters could only output to a few limited video formats. To solve these, a desktop version of PowerPoint to video converter is recomended.

We highly recommend you Leawo PowerPoint to Video Pro, a professional desktop PowerPoint slideshow to video converter app that could help you convert and save PowerPoint presentations to video in 180+ formats for almost all media players and devices.
