This document provides information on the list of known issues in the Adobe Media Encoder.
- Quick Time files with legacy codecs to import as audio only
Issue: The ending of QuickTime 32 support will cause some QuickTime files with legacy codecs to import as audio-only.
Workaround: Transcode files to a supported codec and re-import.
- 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 Quick Time reference files are not imported.
Issue: Some Quick Time reference files can no longer be imported.
Workaround: No workaround.
Support for import/export of legacy 32-bit QuickTime media is discontinued. For more information, see 32-bit QuickTime support has ended.
