Extra { on nvenc preset variable detection causing it to not see the value.

Searching the raw json seems this might be an issue with a few steps total. Here are all of three from this flow at least.
๐ผ | โ Is ffmpeg_preset = faster? (Line 361)
๐ผ | ๐ Check Flow Variable 'nvenc_preset' and determine if it has a valid preset number set (Line 1413)
๐ผ | ๐งฎ Set Local Flow Variable 'use_nvenc_preset' to 'nvenc_preset' value (Line 1429)
Still having trouble getting through nvenc encoding though after these changes but at least it knows what preset to use.
