What exactly is "broadcast standard"?
I'm working on a little 30 second TV commercial for a friend. I called a local cable company (Time Warner) and asked for a technical stardards document that would tell me what all I need to give them.
HER: "We don't have one". ME: (not knowing anything about this stuff) "Umm..OK, what do you accept? HER: "Beta SP. Others on case by case basis if it's broadcast quality". ME: Ummm..OK. What about timings and black video? That type of stuff?" HER: "The usual broadcast standard, sir" ME: "Umm...what's that?" HER: "Bars & tone 30-60 seconds, 10 seconds black, 8 second countdown slate, 2 seconds black, then the spot/video." ME: "Umm....OK, thanks." So my question is, is the 30 seconds, 10 seconds, 8, 2, then spot "broadcast standard"? Like it's universal? Any cable company would accept this? And what does she mean, "broadcast quality"? Something particular I need to do to it? Like color correct? Sorry for the dumb questions. But I have to learn some how. :) |
To answer the 1st part of your question, the answer is yes. The bars, slate, black, countdown are all standard. As far as broadcast quality is concerned, that's a whole seperate issue. I've personally seen commercials on my cable company that look less than professional quality, however if your levels are all correct when you output to tape you should have no issues. I edit with final cut and I always make sure my levels are within the standard guidelines before the tape is sent out. A lot of cable companies still want the spot on beta sp format. So that's pretty standard. I'm not sure what your shooting and editing with, but as an example , I shoot with a canon xl1 and edit with final cut and I have no issues. Hope that helps you.

Broadcast quality means that the signal overall is acceptable for broadcast under the NTSC standards(ie: can they legally transmit the signal within FCC regulations). Has nothing to do with how pretty or ugly the content might be. The bars and tone, slate, countdown are 'conventions' of the industry and aren't legally required. It's like saying the standard billing cycle for all wedding videographers is Net 30 but there may be exceptions.
So folks do equate the term 'broadcast quality' with how nice the picture and sound are. -gb- |

Greg is correct:
Broadcast Quality = Good content, sound and picture quality. Broadcast Standard = NTSC regs etc. Vector scopes and such. FCP will put out to NTSC Standards and has an optional Bars, Tone and Slate to Countdown, Premier Pro should too. XL1's are adequate cameras for Broadcast Standard. But in Broadcast television there is always a better camera. (or one coming soon!) |
What does it typically cost to have someone else transfer a finished video to Beta SP format?
|
Question
Is the standard for bars MSPTE, 100 % or 75%?? |
I would ask them for their deliverables requirements. I used to work for a TWC, and they do have them. My guess is that person just wasn't aware of it.
|
SMPTE bars usually refer to the 75% version.

Production houses will get you for over a couple hundred bucks to make a Beta SP dub. You could try a local broadcast rental company and they may do it for half that.
What I typically do to put a final product on Beta SP is make a Mini DV master and then dub it to Beta SP. If you guys are having problems getting your stuff dubbed over, I have the decks and will gladly help you if you like... for much cheaper than a production house would do it, just pay my assistant. Shoot me an e-mail and we'll work out a plan. |
Hey Adam, I might be able to do that for you. I'm sending you a pm.

Time Warner Quality Issue
Hey Guys,
I recently did 30 sec commercial for a local pizza shop, using Canon XL H1, the, then I delivered in DVD, the quality was excellent. I beleive they trasnfered the DVD to Beta, and when I saw the commercial on TV, it was half of the quality if not lower. I was wondering how can I take advantage of my camera and deliver better quality. I just dont get it, how the national TV commercials are in very high quality, and local commercials are very low quality, same Cable Company, HD XL H1 camera, maybe I do something wrong? Thank you |

Deliver better quality? Don't deliver on DVD. That would be considered a bit of a broadcast no-no. |
There is a differance between just transfering from one format to another - deck to deck- and having someone correct the levels for output to a format that is then handed over for broadcast. Supervised transfers will cost you more however, give you better results. National spots were shot on 35mm, transferred to DIGIBETA or higher - supervised of course - and edited usually at a post house with a very pricey machine. PBS has one of the hardest "broadcast quality" checks in the nation. I have heard of them sending your masters back with actual time code notations of what frames are not allowed. You then go back and tweek those frames and hand them another tape to look at.

I've seen very low quality video on the local PBS channels. I'm very surprised to hear that they have more rigorous standards. Can you elablorate a little more about the kind of thing they would say wasn't allowed Craig? I'm working on a documentary with an eye toward PBS so I'm very interested.

The scanner also costs a big chunk of money... an average film transfer suite might run $2 million. An example workflow is: shoot dailies - transfer film to video; very simple transfer, minimal correction offline edit final color correction online edit (picture), sound editing broadcast master At the low end of the scale, news broadcasts will be ok with poor technical quality (i.e. you have tornade footage on VHS). There are also some TV shows shot on miniDV- this happens with reality and mockumentary-type shows. A show like Trailer Park Boys intentionally shoots on miniDV (PD150?). Not that you can necessarily pull that off... cheaper technology doesn't necessarily democratize the industry. 2- For broadcast requirements, your best bet would be to ask the broadcaster for their technical delivery specs. There is a general recipe for broadcast masters, but sometimes the broadcasters will have very specific requirements (program starts at 1 hour or 10 hour mark; DF or NDF timecode; maximum chroma levels allowed; where program breaks occur). The PAL world is more standardized because of the work of CHEFF: http://cheff.sohonet.co.uk/ChEFF%20C...cification.doc 3- For low-end work (i.e. delivery on formats other than betaSP, digital betacam, HDCAM) the broadcaster may (or may not) have an operator who takes your tape in and manually sorts everything out- they figure out when your program/ad starts, and they figure out your video levels. |
Hi Guys
As well as having the chroma & luminance levels etc at the correct settings there is also an issue with the number of lines associated with the format that you use. For example Pal broadcast analogue is 625 lines of information but Pal VHS is only 400 lines so your image is of a poorer quailty even if your chroma & luminance levels are at the correct settings. Super VHS is about 420 lines and I think Mini DV is at about 585 lines so really with the old analogue system (and I will probably get shot for saying) mini dv is only just acceptable as broadcast standard. Here in Australia there is something known as FACTS wich is the industry standard set out by the governing body. That says something like, you need 1 min of colour bars, 10 sec of black x amount of clapper an 8 sec counter starting from 10 with 2 sec of black & half a second of silence at the head & tail before audio starts & finishes. Check around the internet you will probably find a similar setup in the US. Hope this helps. |

The other lines of resolution figures refer to horizontal resolution, probably TV lines per picture height. It's important to specify a certain amplitude modulation used for measurement, this will affect the # of lines you get. 2- What I was really saying is that certain material will be broadcast for its content... even if its technical quality ain't great. 3- Your lines of resolution figures may be slightly erroneous. MiniDV is limited to no more than 540 TV lines / pH because the frame size is 720 X whatever (720 / 4:3 = 540). SVHS has significantly better resolution than VHS. |

I generally am watching these channels on my Dish Network satellite system though I do occasionally watch what is broadcast locally on an antenna. The quality doesn't seem to change from one system to the other. For some reason the quality of the PBS video in my area is just far inferior to pretty much every other channel on my satellite. I don't know why but it's surprising to hear that PBS is more demanding than other networks as far as the quality of the video. |

That may be possible Greg but it looks the same when I watch it on my antenna. I don't believe it is connected to my satellite system.

"Delivering a DVD is a broadcast no-no"?
Hummm. I've done quite a few commercial for cable insert. I always deliver an avi file on a DVD and the cable company (production division) transfers the footage to BetaSP. I've used this method with several cable companies and no problems so far. Considering that the cable production services charge about $250 for a 30 second spot (that's really 29 seconds) and most of them use less than pro-sumer equipment, I figure they're just happy I'm not giving them Super 8 film :) Same experience with local CBS and Fox affiliates. The CBS affiliate did gripe the first time. (they charge $300 for spot production) After I explained that my/their client wanted to use my production and if they couldn't accomodate us, we'd just buy a schedule on the NBC affiliate - da, da - the changed their tune in a hurry. I probably couldn't get away with this in a metropolitan market, but for now it works. David Bird |

I'm ALWAYS confused :)
Yes, you're right...a file on a DVD is not a video DVD...I should have clarified my statement a little further. Sorry about that. db |
AVI vs DVD
So I should burn AVI on DVD as Data DVD and deliver AVI file?
When I see the Commercial on my Video Monitor, the Colors are excellent. I purchase Canon XL H1 to deliver better quality then the competitors in town, but it seems it was waist. Another question I have, what about MTV reallity shows, ot lets say MTV cribs, what kind of cameras they use, how come they deliver perfect quality on TV? What can I do to be able to deliver better quality then competitors who are using cheaper camcorders. Thank you in advance |
most, not all, MTV shows were shot on the Sony IMX format until recently, when they switched over to XDCAM.

The XDCAM HD cameras do DVCAM and MPEG @HL in 18mbs VBR, 25mbs CBR, and 35mbs VBR. My point being that MTV might still be shooting in IMX, but utilizing the advantages of the XDCAM workflow. regards, -gb- |

In many cases, the production company has no such pull. Don't get me wrong, it's cool that you made it work, but it would be dubious to assume a facility has the means to lay an AVI or QT of whatever codec to the tape format they use for air. |
Nate,
I agree....if I run into a situation where the exact specs (format) are required, I'll have to deliver. db |
