Sorry to tell you that the current version of Wondershare Video Editor doesn't include this function. But we will soon release the version 5.0, which will add the backwards function.

You can double click one of the picture on the timeline. Then in the pop up window, change the duration setting and click "Apply to all".

Hello, by default each picture creates a video of some 4:20 when added to timeline, is it possible to reduce the length of all videos at once when adding many pictures? I mean I don't want to reduce manually the length from 4:20 to a small length one by one since I have more than 300 pictures.

Thanks for your suggestion. We will make the slow motion function more powerful in the future update.
