## Issue
4332: Video transcode setting not reflected correctly (MP3 incorrectly transcoded to MP4)
2 issues here:
(1) The checkbox is mixing between user state and logic state.
(2) The variables (e.g. `optimize`, `isVid`, `filePath`, etc) will have values from the previous operation when you enter Publish Page, so GUI issues beyond Transcode can be also produced (e.g. showing Transcode enabled for an image).
## Changes
The "Transcode" checkbox state (checked vs. unchecked) will now reflect the user's desire and will be a persisted state. Whether or not this setting is used will be reflected by the checkbox's grayed-out state (i.e. it can be checked for non videos, but it will be grayed out).
