Broadcast Video Question(s)

[Bayne]

Alright, so im cutting a TV show and am about done. Its there anything i need to know before it is run off of my computer and sent to the network? Like do i need to deinterlace it, cut the bass out at a certian level, so it doesn't blow out tv's, or is the nework supposed to do that for you?

Its was filmed with 3 DVX100b's at 30p 4:3. Edited at 4:3 NTSC in PP2.

Make sure that all colors are broadcast safe. If not it will drive the engineers crazy.

Call the station you are dealing with and ask them to fax you a "delivery specs sheet". It will have all the info you need in there.

Sorry im a newb at the the whole broadcast safe thing. Vectorscope stuff?

So I set all of the video up with the Broadcast Video plugin. Hopefully this will help the guys at the station...

Different stations - different specs. ozduc is spot on. There are basic things to follow like broadcast-safe colours, no clipping audio, frame rates etc etc., but only the receiving station can tell you 100% what they expect. Some want delivery on Digibeta, others can handle quicktime or TIFF-Sequences. No harm in asking for such specs and they should be used to it.

usually audio levels have to be at -12db (use PP2's audio mixer to check that they average there and dont go above -6db peaks, but again, this depends on the station)
you can also use the yc waveform monitor in pp2 to check your chroma and luma (color and white/black levels) to see tha tthey're broadcast safe.
black cannot be under 7.5 and white can't be over 100

Yeah, well the show aired last night, I got to take alot of notes....like first how to read the damn YC waveform and the vectorscope....

Whites were really blown out to the point that the audio was buzzing overy once in a while. Plus the audio at the end didnt fade in like i set it....it just popped in while they were still talking....PITA.....hopefully it will be better next time.

i'm surprised the station people didn't give you a red flag first when they saw it? When i submitted my commercial recently, they told me there was "discrete motioN" which i didn't get until they described it to me and i realized i was editing in a 24p timeline ..
i also spent hours tweaking the levels and hue to get it into broadcast-safe levels just so they dont deny on any other basis - seems to have been fine.. airing right now on 2 channels

 

[Bayne]

sounds great. You have and tips or hints to bring the turn around time down on post production?

This was on a public access channel here in San Diego, so i guess they didnt care if it was screwed up...just reflects back upon myself tho.

 

[FiddlerMD]

you mean just the "broadcast safe" portion of post?
I only had to do it once so it was kinda time consuming. the thing i did was to import the whole project into one sequence and apply levels to it to bring up the blacks and bring down the whites. the trouble of course is that it depends on what's on screen.
in the future i'll be more careful when i initially start the project (like use a 235/235/235 grey instead of white for text and 16/16/16 black instead of 0 for backgrounds and such .. and just in general while you do color correction, if you keep broadcast standards in mind, i guess that would make life easier

i'm wondering if there's a better version of the "broadcast safe" filter that just adjusts the out-of-spec colors for you
