How should I set up the vector/waveform scopes?
I need to have whites at 100 IRE and blacks at 7.5 IRE. I can't seem to adjust the colorbar provided by VV4 so the pluge drop at 0 IRE.
Any help from the experts ...
AFAIK the scopes are just to adjust off of, not to adjust.
Under the Video FX tab go to broadcast colors there are several new filters you can play around with including a way to adjust what you want. Haven't tried them myself yet. Just taking a quick look it seems the new filters clamp levels so work similar to filtering audio frequencies you don't want. Without checking, I'll assume they work similar to how the older levels sliders worked in version #3 and the new gain and gamma controls on color corrector. They probably don't work exactly the same way but if you look at the histogram you'll see it does impactthe waveform, so another way to fine tune other than color curves.
Like I said in an earlier post when I first downloaded the version #4 beta I've found that just a minor tweaking of the new gain control and balancing it off with gamma and cutting back on hue a little or bumping it depending on the file works WONDERS, along with fine tuning the hues with the color wheels, so much so, I'm in the middle of redoing every video back a year or so, it does make that much difference for the better. I'm really impressed with version #4.
I have found the good values for the 75% color bar on the net. So I can determine that the settings for the scope should be checked (7.5 IRE and 16 to 235).
Now, for the testing ... and I am puzzled.
I rendered 4 files in total from the same 2 PSD files: one 7,5 IRE black (16,16,16 RGB) in VV4 and one in PREMIERE.
I also rendered the color bar in VV4 and in PREMIERE.
Now the results:
VV4 black in VV4 scope = 7,5 IRE, in PREM scope = 0IRE
PREM black in VV4 scope = 14 IRE, in PREM scope = 7,5 IRE
VV4 bars in VV4 scope = 0-100IRE, in PREM scope = 0-110IRE
PREM bars in VV4 scope = 8-92IRE, in PREM scope = 0-100IRE
I am puzzled. But it is not scope adjustments: I can see the difference between the avi's.
Any experts would like to comment? I would like to be shure that what I read is good, as I go from one app to the other regularly. Levels are important to me for my work gets to be broadcasted.
Concerning Billy Boy's comment. I'm editing 5 hours of my brothers trip to Paris. I almost had it finished, then got V4 and started all over again when I discovered what the new color-correction, 2ndary color-correction and scopes could do.
First I set the saturation to about 1.2 (works wonders for this Optura Pi footage).
Then I loop a section of similar lighting and use the 2ndary CC to adjust the vectorscope until I get it fairly centered over-all.
Then I play with the gamma and gain watching the waveform and histogram. I usually bring the gamma up a little so the waveform stays a little above 0 and adjust the gain so that it stays between 80 and 100. Also I seem to get the best results when the average histogram high is around 192.
And finally I watch it on my TV monitor (after having set it up according to Billy Boy's instructions, of course) and sometimes bring the gain down if it's night.
Anyways, getting fantastic results. Go back and look at the original footage and it looks dull and contrasty. I have a lot to learn, but I think V4 is a quantum leap for this kind of thing.
P.S. I can't find my last family movie original footage but I've been searching frantically for it because I, too, want to do it over before I put it on DVD. However, I'll leave the rest as they are.
Cool! I think SoFo should put a coupon in the boxed version for a free tube of Ben-Gay or something for all the head movement back and forth between looking at the external monitor, scopes, then back again.
The sometimes stiff neck is worth it though. Reminds me of sitting through a long tennis match.
BB - "a free tube of Ben-Gay" Really! There's a product for "stiff . . . necks" in the States called Ben-Gay - nah! Truly? - BB - Please, please get me some web-advert links to this stuff! I'm gonna have a field day with it . . . .
Hi Grazie... the funny part is it stinks to high heaven too. I haven't used it in awhile, and don't have any handy to check I think its loaded with menthol and/or some other stuff that anyone can tell you've got on about a 100 feet away.
Another product called HEET is also effective but if you apply a hot compress before applying to open your pores, it burns like hell for a minute or two.
Now for the humor part (sic) They've shown it in a movie or two if memory serves. If you put a good amount of Bengay in somebody's jock strap or underware... hey I went to a rough high school and boys will be boys. <wink>
"hey I went to a rough high school and boys will be boys." - Okay Dokey BB! I'll remember that. Anything else you wish to share with us, now we are on this "Show 'n Tell" - OOoohhh don't you just love Jerry Springer? - Hmmmm.....
Flashback time... Let's see, there was a movie called "Lucas" back in 1986 co-starring a very young-looking Charlie Sheen. Pretty good movie; it was about a young kid who falls in love with an older girl who already is in love with a jock, who... well, you get the idea.
This was Wynona Ryder's first movie, in her pre-shoplifting days.
