Part 1: iMovie Supported Video Formats

As FLV and F4V is not supported by iMovie, in order to import FLV into iMovie, we need to change FLV into iMovie supported video formats. Therefore it is necessary for us to figure out what video formats are supported by iMovie. Here I will show you a table chart listing iMovie supported video formats.

Video Format Abbreviation Brief Description
Motion Picture Experts Group 4 MPEG4, MP4 This is a method in which Audio and Video digital media can be stored; Photos and titles are also supported. The compression ratio is very high, and is suitable for videos that need to retain their high definition, but have a small size.
Motion Picture Experts Group 2 MPEG2 The International Telecommunications Union (ITU) also defines this as the H.222/H.262. This is a generic coding method, which allows for easy transmission and passing of video and audio data, using existing media and bandwidth. The quality is not as high as later versions, but it is backward compatible and is therefore preferred for DVD production.
Advanced Video Coding High Definition AVCHD This is a format that is used for High Definition video; it uses the MPEG-4 AVC/H.264 standard to compress video without losing quality. It was first used by Sony and Panasonic in their Digital Camcorders.
QuickTime Movie MOV This is actually a file container that has several tracks on which you can place video, audio, text and effects. The tracks can either contain the files, or they can have references to where the files are located externally.
Digital Video DV This is a format that was developed for Video Cameras. The video is stored as lossy footage while the audio is not compressed at all.
High-Definition Video HDV 720p, HDV 1080i This was a format that could store high-definition video on a DV cassette, and was originally used by JVC and SONY for their cameras. HDV is easy to import and still maintains the high quality of images in the video.
Motion Joint Photographic Experts Group M-JPEG, MJPEG This is a video format where each frame is compressed as a separate JPEG image; this also applies to an interlaced partition of DV.
