1.0 Beta 4

• Improve MXF support.
• Fix issue with time handling in some situations.

• Improve documentation on MXF DNX variant support.

OTIO Reader playing back variants of DNX HD Media in MXF containers referenced from an OTIO which references media in a path our system doesn't have:

1.0 Beta 3

• Improve Timeline Scroll Performance on macOS 15

• Fix gap handling in AVFoundation editing for video and audio
• Provide a stop gap asset for missing media references
• Provide a stop gap asset for unsupported media file references

The above fixes gets OTIO Reader.app the ability to playback and export more complicated demo assets like AWS Picchu edit:

1.0 Beta 2

• Add support for macOS 13
• Add a Timeline View
• Update Colors to OTIO colors :)

Known issues

• Adding macOS 13 support required adding a now empty sidebar. If you have ideas of what could go there let me know!
