What changes when you convert AVI to ALAC
This extracts the audio and discards the video entirely. The soundtrack inside a AVI file is typically MP3, and it is re-encoded to ALAC on the way out.
Expect a much smaller file. Video accounts for most of the bytes, so about 53 MB per minute becomes roughly 6 MB per minute of ALAC.
Choosing lossless ALAC means nothing further is lost, though it cannot exceed the MP3 track stored in the source video.
When a video holds several audio tracks, the main one is extracted; alternate language tracks are not merged into the result.
About AVI to ALAC Conversion
Extracting ALAC audio from a AVI video pulls the soundtrack out of the RIFF AVI container and writes it as a standalone MPEG-4 (.m4a) file. The video stream, which holds most of the data, is discarded.
Developed by Microsoft in 1992, AVI stores audio using MPEG-4 Part 2, DivX, Xvid. That codec choice sets the upper bound on what any conversion can preserve.
ALAC, from Apple and dating to 2004, uses ALAC and plays natively on 2 of the six platform categories we track. That combination is usually why people convert into it.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
