Episode notes
Apple Uses HLS With Separate Audio Track
- Apple delivers video podcasts via HLS with a separate audio rendition so audio remains rock solid even if video bitrates fluctuate.
- That means when creators flip off video, listeners still get the exact audio soundtrack from the video, so audio quality must be broadcast‑ready.
X‑Restrict Exists But Skip May Still Work
- Apple included an X‑restrict attribute to mark unskippable ad segments, but sources say Apple Podcasts clients likely won't enforce no‑skip.
- The spec gives Apple the option, yet current partner behaviour suggests listeners will still be able to skip ads.
Launch Partners Ship Multiple Resolutions And Frame Rates
- Video encodings vary by partner: launch partners encoded multiple resolutions and mixed frame rates (e.g., 1080p to 240p; 30fps vs 23.976fps).
- Historical TV standards (NTSC/PAL) explain why US partners often use 23.976fps while others use 25fps.
