About converting AVI to MP4
AVI is an older Microsoft video format with broad but dated compatibility and larger files. MP4 is the most widely supported video format, playable on virtually every device and platform. Converting from AVI to MP4 swaps one for the other without changing the underlying content.
Re-encoding video is lossy, so we use quality-preserving defaults — you can still tune the resolution, quality, and frame rate before you start.
