Why export podcast MP3 straight from legacy AVI instead of MOV round-trips?
DVRs, old field recorders, and classroom stacks still spit AVI while your RSS host only wants a small MP3 attachment. Searchers type avi to mp3 podcast, dvr interview mp3, mjpeg extract audio mp3, and legacy tape digitize mp3 because the pain is gateway limits, not container religion. MP3 stacks another lossy generation, but when stakeholders cap attachments and ban WAV, a conservative speech preset beats bouncing through heavyweight editors at midnight. Interleaved PCM inside AVI can look like lip-sync drift if resamplers disagree—spot-check consonants on headphones before you batch hours of tape. Multi-track AVI layouts usually flatten to stereo unless you solo stems in the timeline first. Faces, music beds, and confidential quotes still follow your release contract even when pixels disappear. Ai2Done keeps the podcast variant procedural: trim silence, export a short RSS test upload, checksum-link AVI and MP3 in the ticket, then ship the episode.
How to ship AVI interview audio as an RSS-safe MP3
- Open AVI to MP3, pick the podcast variant, inspect whether video is MJPEG or DivX and whether audio is PCM or compressed, then read upload caps.
- Match speech bitrate and 48 kHz sampling when your host contract demands it, solo the dialogue bed inside the edit if multiple tracks exist, then export.
- Upload a private test episode, listen on phone earbuds and car speakers, then checksum-link derivatives before anyone deletes the AVI master.
