Matching OTT/Broadcast Specs via Premiere or AME

Does anyone have experience handing off video creative to various streaming and broadcast outlets? I work for a financial institution. As one of the primary video creators for my org, the scope of my role includes working with a lot of outside media partners, buyers and vendors. As such, I'm tasked with sending out the various video files for our TV commercials, all of which were produced by outside production companies.

My biggest hurdle is trying to modify the video files to meet the specs of the different delivery channels; for example, these spots run on Peacock, Hulu, etc. I've been given one-sheets, and, in this instance, I'm struggling to match all the attributes for Hulu.

I can often get close, but I have yet to find a way to customize all the above specs. Are Premiere or Media Encoder the right solutions for this? Or is there other software I should be using to "dial in" these settings?

Furthermore, where can I find all the granular metadata? Since I've yet to figure out how to customize each attribute, there are parts of these files I'm exporting blindly. However, when I pull them into our digital asset management platform, it gives me a whole lot more metadata than I've seen anywhere else.

Thanks in advance!
