Turn a Video Into a Podcast Episode
Podcast platforms only accept audio. The job is a correctly specified audio file plus text materials you can largely reuse from subtitles.
Step 1: keep only the audio
Picture is the bulk of a video file; stripping it leaves roughly a tenth of the size. Choose stream copy when the source track is already mp3 or m4a — fastest and lossless.
If the source codec is exotic, re-encode to mp3 or m4a at standard quality; for speech, the difference from high is inaudible.
Step 2: match the platform format
Major platforms accept mp3 and m4a; mp3 has the widest reach. 128kbps mp3 is plenty for speech; music-heavy episodes start at 192kbps.
If the episode is long and large, compress audio down to a target bitrate — 96-128kbps is the common landing zone for talk content.
Step 3: show notes from the transcript
Auto-transcribe the audio, then edit the draft into show notes — faster than writing from scratch and doubles as a fact-check pass.
Pre-publish checklist: duration correct, no dead air at the head, consistent loudness, and the cover is a separate image file uploaded in the dashboard (not embedded in audio).
