PLEASE I GOT A JOB !!!! but whats this????

Sounds like they want the material delivered on analog tape.

[Tom Wolsky] “Sounds like they want the material delivered on analog tape.”

The “what’s this???” part is how TV gets to your house. 🙂

Did they say what tape format? This is kind of important.
Most likely BetaSP, (but could be something else like (shudder) 1″).

Standard RS-170A NTSC OK, that’s what we use here.
Video 100 IR (Maximum level of white) Use your Scope* (The term is IEEE, old-school term was IRE)
Level of black screen 7.5 IRE +- 2.5 Use your Scope
Maximum level of synchronizatio 40 IRE +- 2 Use your Scope
Maximum level of burst 40 IRE +- 2 Use your Scope
Initial line of information 20 / 21 Line 21 reserved for closed captioning
Tone of Audio 0 VU Use your audio meters

Recorded on DF, LTC and VITC “Recorded on” ??? Maybe “recorded using..”
DF= Dropframe Timecode – Timecode frame count altered to match equivalent clock time**
LTC=Linear Timecode – the Dropframe Timecode is recorded on the analog VTR’s dedicated timecode track
VITC=Vertical Interval Timecode – a digital version of the dropframe timecode is embedded in the vertical sync interval, usually line 16-18.
The analog VTR’s timecode settings are used to enable VITC and set it up properly.

How do I read the waveform???? to read those values?
level of black screen 7.5 IREfor example?

[Chuck Reti]

Again I refer you to Tektronix

See also your FCP manuals. In Vol III are Waveform monitor and Vectorscope and how to read them.

It’s a bit beyond the capability of a text-based forum like this one to deliver a course in video measurement techniques.
Use the Profusely Illustrated resources available on the web, if you don’t like the Tek document, Google “video waveform monitor” or “Video Measurement” and hundreds of other tutorials will come up. Go to the TV station that wants to air your spot. Talk to an engineer there. See if there’s a local SMPTE or SBE chapter in your area; they might offer some assistance.
If you’re going to work in video, know how video works.

[Heriberto Levin]

thank you so much….

I will read the tektronix document…
going to the station is certanly not an option considering that the comercial will air in the USA
but I am in Nicaragua …. thank you so much for the help… will try to undertand the waveform

The waveform in FCP looks very different than the samples to
learn how to read them at http://www.tek.com

any sample reading from a FCP waveform vectorscope that has legal values ??

thanks!!!!

[Uwe Klimmeck]

You can rent a scope for example and take two days to learn how it works.
Kind of basic stuff for an editor to know anyway…..
You need to be able to measure what’s on tape and this does only work with an external component scope.
If possible rent a waveform / vectorscope combo.

All the best

You can’t use the FCP scope for this kind of work though. You really need an external scope which will tell you what the external analogue signal is doing.

On the more digital side of things, this article I wrote shows what is going on in FCP and how digital and analogue levels can relate:

Since you’re not going to own the VTR to output onto, just take those specifications to a post facility for transfer. They’ll have everything in place, and hopefully properly calibrated. And probably cheaper than renting a VTR for a day.

[Mike Cohen]

There was a time when I spent as much time looking at the scopes as I did my editing display – remember magnifying the sync part of the waveform so you could time the H-phase? Oh the memories.

Apparently they don’t teach these skills anymore at video programs, only engineering.
