Hello,
You cannot have VOD assets delivered using a “live” stream type application.
Regarding your second remark, you are correct. It wouldn’t be efficient to record using the Wowza Manager user interface. You can develop a custom Wowza module and record your transcoded streams programatically, as described in the “How to record live streams (HTTPLiveStreamRecord)” forum article, in the “Recording live streams programmatically” section.
Also, you can generate multiple renditions of a recording, having the VOD assets properly key frame aligned by using FFMPEG. Please take a look at the following forum thread for an example on how to use FFMPEG to generate key-frame aligned VPD files: Frequently requested FFMPEG command examples for Wowza
