Broadcast specs question

[michaelb84051401]

Hi, was wondering if someone could help me out here.  I received broadcast specs for an ad that doesn't seem to match up.

They want:

"

5 seconds of Slate (frames 0-149)
2 seconds of black spot (frames 150-209)

Start frame – the spot must start on frame 210 at 29.97fps. The creative content must run to the last frame of the spot with no black at the tail for a total of 1110 frames.

"

So if I create a 5 second slate it actually ends up being 150 frames, and not 149 correct?  Is this a typo on their end?  I just wanted to make sure I'm not missing something regarding Premiere Pro. When I place the spot after the two slates, the 30 second spot now ends up shifting to frame 212 instead of 210 of where they would like it to start. 

Thank you for any help and background on exporting for broadcast!

Your timeline starts at 00:00:00:00.

The first frame of your slate is at 00:00:00:00. Zero is a number. If I ask you to start counting fingers with the first finger starting at zero, how many fingers do you have?

An easy way to see this in Premiere is to check your duration by marking an in and out point - you'll see that if you start the slate at 00:00:00:00 (mark an in)  and end the slate at 04:29 (mark the out) you'll have a duration of 5:00:

Understanding timecode and how the playhead works with a mark Out (and how Mark Clip might be a better way to mark that range) is a Premiere 101 concept I like to teach before lunch on the first day of instruction. It is that crucial and what seems to be going on here. If I am being presumptuous, please excuse me.

It's easy to understand how some editors work for years not realizing this super important concept. Once one zooms all the way into a Mark Out done with the Playhead, then the mystery is unlocked. The Playhead represents a full frame (:01) and has a "tail" to it. So,it's not just a "needle." If you mark Out with the Playhead, you might be cutting off a frame on something like a Ripple Delete. 

Marking Out with the playhead cuts an extra frame

That's why I use Mark Clip or if using the Playhead, I move it left one frame, then Mark Out manually.

Mark Clip creates proper In and Out marks

Marking durations more precisely also requires one to know about these small nuances regarding how NLEs function. I bring this up because I found over the years that this concept escapes most people, especially self-taught post-production folks. I should probably create a FAQ around this info. What do you think, Mr. Dog?

Hmm. I just did this in a timeline to check and my media start is at 210 with those specs, end frame lines up as well.
