Confusion surrounding dissolves from/to black
Over the years, I have noticed that sometimes when applying a dissolve to, say, the first shot of a show at 01:00:00:00, the first frame has picture and isn’t completely black. Then, on other occasions, the first frame IS black. If the specs call for the first frame of picture to start on the hour, I have to open the effect editor and drag the keyframe back to before the cut. Same for shows that need picture until the very last frame specified by the broadcaster.
Is there a setting for this?

What you’re seeing is correct.
The first frame of your program will not be black, but the first frame of the transition – a very dark picture. Effectively, if the first frame of the program was black, then the fade up would be commencing 1 frame in.What you are currently seeing is both correct and standard practice.

Thanks Neil. What my issue is though, is that often it is black (0 luma) on frame 0, but sometimes it has been a very dark picture, but not black. I am looking for a setting that makes my dissolves show dark picture, not black, on the first frame of the dissolve. I don’t understand why this wouldn’t be a default, since broadcasters, more often than not, want picture on 01:00:00:00, not 01:00:00:01.

I’ve always treated it like this.
Put however many frames of black that you want at the head of your show….now step through the frames, and watch your waveform.
Black…black…black…black…first frame.
How do you know its the first frame?…because the waveform started to change.
In most broadcast outputs, im still putting slate and black before the first frame anyway, but the first frame is at 1 hour straight up, not 1 hour and 1 frame.
I’m sure someone will state otherwise, but I’ve never had a show sent back because it was 1 frame short.
Of course next you will be wondering about the end of the show…does it end on the last frame of picture, or the first frame if full black…assuming you do a fade out.

Place a black title clip on a track above the first image visual. Fade out the black clip and snap the beginning the fade out of the black clip to 1:00:00:00

are you seeing this within MC or in your output? If in your output, is the format an mpeg format? If so, that’s the nature of the compression. I spent a few days years ago, trying to figure out why I wasn’t seeing clean black at the beginning of my outputs. Finally figured out to make sure I had clean black on the first frame (and last frame) of a sequence, I needed to add a few frames of black at the beginning (or end) of the sequence.

My apologies for the way late response. I’m seeing this in MC and on my scopes.
My issue is that it’s inconsistent. Sometimes I get a show from offline, and the last frame of a dissolve is (very dark) picture, and sometimes it is black.

Thank you. It’s not so much that I’m concerned about the show being short, because I catch it and adjust the effect, but it’s more about the inconsistency. Sometimes I get a show from offline, and the last frame of a dissolve is (very dark) picture, and sometimes it is black.

When there is inconsistency between two dissolves, is the length of the two dissolves the same? Is it a cross-dissolve, film dissolve, or fade from black effect?
