At some future stage, will AME have a batch frame rate conversion feature with interpolation? That being I can send to a queue a stack of clips with varying frame rates and output all the input files to a same end output file frame rate but leave the audio part of the file untouched to same pitch and duration? Say a collection of 12, 23.97, 24, 29.95, 30, 60 fps and all resulting output conversions at 25 fps. At present I am using AWS Elemental Media Converter which is pretty costly.

Also, why when converting an AOMedia AV1 video file to h.264, the resulting AME conversion only carries audio through and not vision? Does AME have support for AV1 files, or is that still coming?

Currently, adding a subfolder to an ingest preset involves recreating the ingest path in full. I always use the same path for my ingest preset but need new folders for each media card. Just a simple addition of adding a subfolder without needing to create a new custom path would streamline the ingest process. Overall, ingesting through Media Encoder is the only way I can ingest to multiple locations at the same time and much better than needing a third app like Prelude (which I only ever used for ingesting). I like not having to create a prelude project just for ingest, but the ingest features need to be ported into Media Encoder for easier sending to multiple locations and creating subfolders.

I need to be able to batch modify "Source Settings" on ProRes Raw clips in Media Encoder. Currently the colorspace for ProRes Raw clips has to be set on a per clip basis by right-clicking clips in the Media Encoder queue and choosing Source Settings and then setting the colorspace as desired (the colorspace always defaults to Rec709). If I select multiple ProRes raw clips and try to modify Source Settings, the change is applied only to the first clip in the selection. I need to render hundreds of clips using the Sony slog3/sgamut3.cine colorspace setting but as it is, they will all have to be modified one at a time. It also does not make sense to that colorspace is segregated into a separate "source settings" dialog - it should be a setting that is set and stored as part of the encoder preset settings. I cannot use the "generate proxy" feature directly from Premiere because I cannot store the desired prores raw colorspace setting in the ingest/encoder preset. Please fix this. Move Prores Raw colorspace settings into the encoder preset settings, so it can be saved as part of the encoder preset and then batch applied to all clips in the queue. Thank you.

Recent update (MediaEncoder 22.5) has a horizontal scroll bug in Preset Browser window and Queue window. I use Apple Magic Mouse to scroll horizontally - so historically in Media Encoder if I scrolled right, I got to see right side content, and if I scrolled left, I got to see what's on the left. But in 22.5 (Build 57) update, horizontal scroll direction is inverted for Preset Browser window and Queue. Media Browser window still acts normally when I scroll horizontally in directory tree.
I hope it wan't done on purpose - my brain just doesn't work this way. The scroll behaviour should be the same across all Adobe apps.

1- It would be nice to get basic corrections (brightness/contrast/saturation/white balance) + lens distortion correction directly in Media Encoder, without needing to create a project in Premiere Pro.

2- It would be nice to be able to save the above settings as templates to be quickly reused

Example use case: I often use Media Encoder to stitch clips from GoPro cameras to get a single video file & reduce file size. Sometimes I would like to add basic corrections to fix brightness and lens distortion (reduce fisheye). It can easily be done in Premiere Pro but it would be so much more convenient and quick to be able to apply the settings directly in Media Encoder and to be able to save/reuse those settings.
