Looking for Post-Live-Event using Qumu QCS 2.8 with VCC 7.5

Hello -

I am attempting to support a deployment of Qumu Webcasting solution to 120k+ users.  The modalities are Smooth Streaming, HLS an MP4.

STREAM   Premiere Pro​ !

======

MP4

- Video

- Audio

Slides

- JPG

- "Slide Change Events"

DATAPOINTS

=============== 

@ENCODER (QCS)

   - Archive Video  - MP4 and Expressions XJE file

@8550554 Storage

   - PPT (images) - JPG files

@8550554 DB

   - Slide events - in SQL storage

EVENTS NEEDED, BUT NOT SUPPORTED BY VENDOR

=======

1. Replace PPT image file with correction

2. Remove mid location cough

3. Ability to browse via NLE Non-linear editing system - Wikipedia, the free encyclopedia 

4. Ability to mount Qumu Stoage / DB

MY IDEA: 

========

1. So I found that I can open the QUMU archive output with MSFT Expressions Encoder Pro 4

  - It does not include the slide events

2. I think I could create a custom plugin to MSFT Expressions for slide events via SQL queries

MY ASK:

=======

Is there anything better from Adobe side to mount MP4 (Audio/Video) and custom API for PPT for slide images to allow for full CRUD actions?

Corrections / Comments?

Thank you
