I will often times send something from Premiere to Media Encoder for exporting. Many times I am creating multiple version, so I have a folder of presets that I drag onto the file and I get my 6 different version of the video. I have Media Encoder set to append the preset name to the filename.
Othertimes I am not choosing a preset, but i am doing custom settings in Premiere and when I send it to Media Encoder and it will automatically append a preset name to the end of the filename. I *think* it chooses the most recent preset that I made/saved, but the preset column will say "custom" but the filename will have a preset name appended to it. I'll be exporting a 4K file and the filename will have "1080 w-captions" appended to it, even though none of the settings chosen are from that preset.
I am using Premiere Pro 25.2.3 and media Encoder 25.2
I am running macOS 14.7.6 on a Mac Studio M1 Max with 64GB of RAM.
This has been an issue for a few years now, and I always assumed maybe it would be fixed, but maybe I'm the only person who is running into this. (Finally annoyed enough today to complain about it.)
