Make every video clip you record more interesting with the Slow motion & fast motion mobile application. Through its built-in recorder, you will be able to make sped up or slowed down recordings. Highlight the key points or emphasize certain scenes by applying special effects to them.
You can adjust the recording speed while shooting, or you can apply new settings to previously recorded clips. Moreover, the app allows you to pinch the screen to zoom in and focus on your subjects better, take photo stills, and more.
Slow motion & fast motion is compatible with most Android devices. You can download and install it for free.
