I’m using FotoMagico 5.6.13. After adding a video to the Timeline, is there a way to change its playback speed (either speeding it up or slowing it down), or does that have to be done outside FotoMagico before using the video in a slide show?
You’ll have to use an app outside of FotoMagico to achieve what you want. FM will only playback a video at its original recorded speed.
Yep. You have to use another software to change the speed of the video and then to add it with the modified speed. It is not that hard actually, so if you have never done it you can find the ways in this article. It is explained very clear so anyone could do it.
