I've used Media Encoder to create proxies before, but this time when I launched it there was no Ingest Check Box where it was supposed to be and no settings next to it. I have CC 2020. According to all the tutorials, this is where the button should be and is where it has been in the past. I have tried deleting the app and re-installing, syncing the settings, resetting the workspace. Nothing has worked. Where did the button go? Am I the only one having this issue? I'm not sure how to create proxies without it.
I'm looking at Media Encoder 2020 and 2019, and they exactly like your screenshot. I guess my process for creating proxies is slightly different. However, there are a lot of ways to create proxies.
Premiere Pro uses Media Encoder to create proxies. Personally, I import everything into Premiere Pro, and then I decide which videos I want to actually create provies for because some videos I know that I won't use. After your videos are imported, you can right click on them in you Project Panel and go to Proxy > Create Proxies... (screenshot attached, which is my preferred method). This will automatically launch Media Encoder and start creating proxies and attach them in one fell swoop.
Another option: you can also create your proxies in Media Encoder first, and then attach the proxies.
Yet another option: you can set this in your Premiere Pro project settings to do this for every single video that you import into Premiere Pro.
Hope these options help!
