Problem
An RSS migration preserves audio files but loses chapter artwork references, reducing the usefulness of chapters on compatible podcast applications.
Solution
Root Cause / Diagnostic:
Migrating between podcast hosting providers often migrates basic audio enclosures and RSS item nodes while discarding custom chapter-level image URLs stored in proprietary CMS databases. Without explicit Podcast 2.0 <[link removed]> JSON file transfers, chapter image pointers fail during feed import.
Actionable Fix:
1. Backup and export the complete Podcast 2.0 chapters JSON schema and verify that image assets are hosted on an external, persistent CDN (AWS S3/Cloudflare R2) rather than host-tied storage.
2. Re-embed chapter artwork directly into the ID3v2.3/ID3v2.4 APIC sub-frames of each chapter marker within the master MP3 file using tools like Forecast or MP3tag.
3. Test the migrated RSS feed in an advanced podcast client (e.g., Pocket Casts) to verify that chapter-specific artwork renders correctly at each designated timecode.
Pro Tip:
Embedding chapter artwork directly into MP3 ID3 frames ensures persistent visual chapters across all legacy and modern podcast clients regardless of future RSS host migrations.
