Composer

Composer will help you to merge and crop video and audio. It can also make a video out of images.

Few use cases of Composer are as follows,

• Merge video and audio files into one video
• Make a video out of images. You can also tell how long it should display a particular image.
• Add a background audio track to a video/videos and make it loop
• Create thumbnails for videos

Composer uses AVFoundation to make the above possible.

Todo:

• Add transition effects
• Deal with videos of different resolutions and frame rates
