Known issues in Adobe Media Encoder

• Issue: Export Settings dialog may not close if Adobe Stock is enabled in Publish settings. This can happen when current export settings are prohibited by the Adobe Stock service. No warning dialog is shown in this scenario.
  Workarounds: Adjust export settings so that duration is less than 60 seconds, frame size is greater than 1280x720, and make sure you’re signed in to your Adobe Stock account. If that does not work, disable the Adobe Stock destination
  

• Issue: Export Settings dialog does not close if Publish to Behance is enabled and Description or Tags field is empty.
  Workaround: Fill in the fields to continue.
  

No warning dialog for unlicensed Stock Audio in Adobe Media Encoder.

• Crash occurs during export
  Issue: Crash when exporting a sequence with ProRes media with an embedded LUT from ARRI cameras.
  Workaround: Export directly from Premiere Pro.
  

• Dragging a scene from Character Animator to Adobe Media Encoder's queue doesn't honor Work Area setting
  Issue: By default, Source Range is set to Entire Composition. If you change the Source Range to Work Area, the In & Out points are set to the beginning of timeline.
  Workaround: To handle the work area setting correctly, use File > Export.

• Lossless audio from WMV is imported as noise (Win10 build1809 only)
  Issue: When you import WMV with lossless audio, you do not hear the original audio.
  Workaround: Do not update to Win10 build1809. Instead use the Win10 build1803 or earlier versions.

• Adobe Media Encoder hangs when trying to reingest a camera structured source.
  Issue: Adobe Media Encoder hangs if you turn on/off the transcode option in Ingest settings when trying to reingest a camera structured source.
  Workaround: Specify a different copy location.

• QuickTime files with legacy codecs to import as audio only
  Issue: The ending of QuickTime 32 support causes some QuickTime files with legacy codecs to import as audio-only.
  Workaround: Transcode files to a supported codec and reimport.
  

• Audio is out of sync
  Issue: Audio is out of sync by several 100 samples in H.264, MPEG-2, MPEG4, when multiplexing audio and video streams.
  Workaround: None, except encoding into a different format with uncompressed audio such as MXF.
  

• With H.264, AAC audio is truncated at the end.
  Issue: When you use H.264 on the fly muxing, AAC audio is truncated at the end.
  Workaround: Use VBR 2-pass encode or use MPEG audio.
  

• Encode Error
  Issue: Encode error when DL-queued from Premium Pro and encoded into the matching QT ProRes video setting as the source.
  Workaround: Check the "Import sequence natively" option.
  

• Some of the QuickTime reference files are not imported.
  Issue: Some QuickTime reference files can no longer be imported.
  Workaround: No workaround.
