Opening steps

Choose your environment or purpose to see its steps.

An editor with AAF import support

Preserve the original and inspect a working copy in a compatible application.

  1. Confirm importer support and requirements.
  2. Import AAF with its accompanying media.
  3. Compare timing with reference picture/audio.
Inspect the received file and its requirements

Establish dependencies and settings before proceeding.

  1. Check versions, frame rate and start time.
  2. Identify embedded versus separate media.
  3. Agree handles and channel-splitting requirements.

Menu labels and support vary by app, OS and version. Preserve the original before making changes.

Troubleshooting by symptom

  • Media offline: check separate payload delivery.
  • Sync shift: compare start timecode and frame rate.
  • FX missing: compare rendered references for unsupported effects.
  • Export fails: inspect embedded-size and version limits.

AAF → compatible editor import

  1. Test a small timeline before the full handoff.
  2. Reopen the output and check it against the preservation points in this guide before handoff.

Do not assume complete preservation of plug-ins, nesting or effects.

Handles provide editing room

Agree extra media before/after edit points; tightly trimmed clips limit later changes.
