Delivery specs should be communicated to you by whomever you are working with. This is not something you should be guessing about. Ask! For broadcast, the delivery is usually a high res 10 bit HD file, not H.264. At least, in my experience that was the case.
Do you perhaps have a recommendation for what format the clips I use for editing should be, if the end result should be for a TV ad? Does it matter if it's MOV or MP4 for instance, and does the fps of the clip matter? I've read that 30 fps is recommended.
Very few places broadcast at ATSC 3.0 standards. For ATSC they will probably want 1080i. as opposed to 720P 60. They might want bar and tone and a count down lead among other things. That being said you should be using a video capture card like the Intensity Shuttle and a broadcast compliant monitor that can display 1080i. You can put H.264, Pro Res, BRAW etc in the 1080i timeline. They might accept an HDV tape or Blu-ray disk. Every place will be different. You need to ask the broadcast facility how they want it delieverd not us.
You can render out a 1080p sequence to 1080i. That being said you cannot watch 1080i on a computer monitor. For that you would need 3rd party hardware and a broadcast compliant monitor. If you are going to do a lot of broadcast work you need 3rd party hardware for accurate color space, composition and motion. Motion graphics are silky smooth at 1080i on broadcast compliant hardware.
