High Frame Rate transcoding does not go higher than 60fps
Plain and simple: bring back high frame rate encoding. It was in AME 2019 and at some point it was removed. Could this have anything to do with conforming to 'broadcast standards' related to timecode? As time code doesn't exist in formats faster than 60fps. Find a way around it because this is an essential editing feature request. ProRes is not solely for broadcast delivery, in fact it is the backbone of most editing pipelines who choose to not edit native.
This issue was resolved in Media Encoder v22.5, which was released on June 20, 2022.
