Short answer: if you need the AVI for iMovie or an iPod, the safest target is an MP4 containing H.264 video + AAC audio (or Apple ProRes if you want maximum editing performance). iMovie accepts H.264/MP4 and Apple recommends ProRes for best editing performance (larger files). (gist.github.com)

If you want a simple GUI tool, use HandBrake (free, macOS-ready). Add one or more AVIs, pick an MP4/H.264 preset (there are presets tuned to Apple devices), set “Video” to H.264 and a Constant Quality (RF) around 18–22 for good results, set audio to AAC 128–192 kb/s, then Start. HandBrake supports queues/batch jobs and can use macOS hardware encoders when available. (handbrake.fr)

For power users ’s ffmpeg suggestion is solid. Two useful commands:

Remux (fast, no re-encode — only if codecs are already MP4-compatible):

ffmpeg -i input.avi -c copy output.mp4

Re-encode (guaranteed compatibility, good quality/size tradeoff):

ffmpeg -i input.avi -c:v libx264 -preset slow -crf 20 -c:a aac -b:a 192k -movflags +faststart output.mp4

CRF controls quality (lower = better; ~18–23 is common). -preset trades encode time for compression efficiency; -movflags +faststart makes the file stream-play friendly. (owlclip.com)

Troubleshooting notes: if iMovie still refuses a file, the AVI probably uses an old codec (DivX/Xvid) and must be re-encoded; rewrapping won’t help then. For flawless editing, transcode to ProRes (Compressor or ffmpeg’s ProRes encoder), but expect much larger files. Avoid relying on VLC’s GUI “Convert” for bulk transcodes — there are known edge-case bugs (stream order/metadata) that break playback in Apple apps. Test one file first, check audio/video codecs with ffprobe, and then batch. (avpres.net)

Try ffmpeg. That is a command-line tool, but there is a graphics interface for the Mac. The main tool is at www.ffmpeg.org. The Max GUI interface for it is at www.ffmpegx.com. It is possible that the ffmpegx install will also include ffmpeg itself. Anyway, it will let you convert just about any video format into any other.
