Editorial_pkg: publishing sequence into OTIO timeline with rendered media

[moonyuet]

Changelog Description

Implement a sequence-based workflow for publishing an editorial package in Unreal. This workflow should publish the OTIO timeline and an intermediate render in MP4 format.

Resolve #131,
Resolve #125
Resolve #124

• otio representation implementation
• Has unreal_export.py edited for the otio implementation
• Edit rendering.py which can be used for both rendering and editorial intermediate rendering

Additional info

-It may need multiple testing to get the correct frame ranges
@jakubjezek001 this is the zipped file with otio and the clip: editorial_pkgMain.zip

Testing notes:

1. Select level sequence which includes MovieShotCutTrack/CameraCutTrack with multiple sections
2. Create Editorial Package Instance with it
3. Ayon -> Render
4. Wait to render out all the sequences until finished
5. Ayon -> Publish
6. It should publish successfully with mp4 and otio
7. Load otio in hiero/resolve

@moonyuet pls add testing steps once it make sense to test it out (now they are not present). thx!

I have prepared level and sequence for rendering with 3 camera cuts

created Render instance and Editorial instance using that sequence but when been in step 3) of testing (trying to Render) Im getting following error:

LogPython: Error: Traceback (most recent call last):

note: Your testing steps are still a bit sparse, so if I get it correctly I should first create Render instance to be able to render out image sequence and then using that same level sequence create Editorial publish instance. First producing the rendered images via Render action and later on use publish action for publishing both Render and Editorial as a final step...

Im stuck due to the aformentioned error on the step 3 atm

You can merely create editorial package instance for this case to render the out sequence(no need to create render instance). and then hit Render and then go to Publisher UI and Publish the editorial package.

Ok so I have skipped the Render instance and just selected the Editorial package publish instance....after hitting Render it has finnished the rendering but once trying to Publish the Editorial package it fails on extract Intermediate Representation and throws following error msg:

here is my episodes_seq and how it looks btw (I hope its correct, as it works well with cam cut)

Can you show me all the rendered files in C:\Projects\Quantum_Demo\UE\temp_renders\Quantum_Demo\editorial_pkg\episodes by screenshot ?

[LiborBatek]

Yep, all shots render present and be in correct clip in and outs...nice!

I have updated commit and all the rendered files in C:\Projects\Quantum_Demo\UE\temp_renders\Quantum_Demo\editorial_pkg\episodes instead of all the rendered frames to be saved depending on how much subsequences you have. And the intermediate representation should be rendering the video accordingly, which means @LiborBatek you need to re-render it again and then publish.
