  • Audio mixdown information
  • Basic effects and transitions

FormatStrengthWeakness
AAFComprehensive, audio-focusedComplex, sometimes incompatible
XMLFlexible, easily readableLess audio information
EDLUniversal, simpleOnly basic edits, outdated

Practical Tips

Export from Avid

  • "AAF Edit Protocol" for maximum compatibility
  • Consider Embedded Audio vs. Linked Audio

Export from Premiere

  • AAF is less reliable than XML
  • Still the standard for audio export

Import into Pro Tools

  • Prefer Linked AAF (saves space)
  • Synchronize session settings beforehand

Typical Problems

  1. Timecode Mismatch: Check start timecode
  2. Missing Media: Relink paths
  3. Effects Not Transferred: Use native effects
  4. Audio Levels: Clip Gain vs. Track Volume

Perspectives

Cinematographer

Als DoP interessiert mich AAF vor allem, weil es meine Farbkorrektionen und Metadaten über Linsen, ISO und Belichtung zwischen verschiedenen Systemen bewahrt – so gehen meine visuellen Entscheidungen nicht verloren, wenn der Editor ein anderes Programm nutzt.

Director

AAF ist für mich ein Rettungsanker in der Post-Production, weil ich damit mein Schnitt-Projekt nahtlos zwischen Avid und Premiere wechseln kann, ohne dass mir die Timeline, Effekte und Markierungen durcheinander geraten.

Producer

Durch AAF spare ich Zeit und Kosten in der Postproduktion, da meine Teams effizienter zusammenarbeiten können und nicht jede Software-Inkompatibilität zu teuren Re-Exports oder Neuschnitten führt.
