How to match HVX-200 and DVX-100 footage of same scene?

[filmtovideo]

I have a multi-camera shoot, one HVX-200 and two DVX-100s (not sure
which models) coming up. The director wants to shoot 24P.

I'm a lot more familiar with the HVX-200. What are some cine settings
that would help to match these cameras, all rolling on the same subject
(two actors) at the same time?

Any other thoughts on matching? Thanks!

My experience trying to match them once is that they were extremely close. In my case the HVX was cleaner and needed to be at +6 to match noise on the DVX, but that may depend on the DVX 100 model

With identical settings I only needed to adjust 1 point of chroma saturation for a perfect match. Can't remember which way but that should be obvious with a decent monitor.

Cool, thanks. The plus 6 was detail, is that right?

[Lenilenapi]

No No No, not detail, +6 detail would be very high.

Detail you may have to check out yourself. The HVX might need a little bit higher detail setting than the DVX but I'm not sure. It might not though it seems to me that I noticed once in 480 that the HVX was a little softer than the DVX.

I was referring to +6 DB gain. For all its supposed noise, the HVX is much quieter than a DVX100A and it needed gain to be a perfect match. You might not want to "dumb" it down for your purposes though. Noise is probably comparable on a DVX100B since its newer.

do you have any facts to back up this statement about the 100b being less noisy then the 100a??

That makes sense. Thanks for clarifying.

Just picked up the other two cameras. A DVX 100A and a DVX100B...to go with
an HVX-200! (I like them all; it'll be fun.)

the 100b is cleaner than the 100a. Funny cause i find my 100a to be BUTTLOADS cleaner than my HVX.

Jan Crittenden confirmed the noise difference on the cameras. AS for +6db... I wouldn't go that high. Maybe +3?

The HVX is noisy... If you shoot at night with gain. Try Detail coring +3 and presto. No more noise.

[Lenilenapi]

TimurCivan,
Hmmm , you may know more than I since only compared them once on a set and you actually own them.
Maybe it was a DVX100 but i think it was an A.

Well i also have my DVX100 set up to be practically noiseless.

And at the time i had the HVX tweaked for max Dynaic range, so perhaps, thats why. i have heard from other peopel that the HVX was cleaner. i just never had that experince. i need to test it.

I just finished a shoot using the HVX and a DVX100A. To match them, I ended up pushing the gain on the HVX to +6 and pushing the detail on the DVX to +3. The HVX actually needed between +9 and + 12 for a perfect match since it is about a stop and 1/2 slower than the DVX but I was afraid of too much noise and figured the rest could be done in editing. I also slowed the HVX shutter to 1/24th. I was shooting at the end of the lense most of the time so there was a lot of glass to go through otherwise they would have matched easier.

Were you shooting at 24P? What scene setting were you using?

Also, I have my HVX-200 gain set to "0" on all settings but even if I
were to change it, how does the gain help in matching
noise because doesn't the gain kick in only when the aperture is wide
open? Is that the point, to shoot wide open with the HVX-200?

Also, I'm thinking of setting the vert. freq. to "thin" on all three cameras?

Thanks everybody.

If enabled, the gain is active all the time no matter what aperture you are shooting at.

If enabled, the gain is active all the time no matter what aperture you are shooting at.

Why? It seems to me that if gain electronically increases
brightness but at the expense of noise, then it would only be desirable
when you couldn't open up the lens anymore and so you use gain to
get brighter. I was shooting with A DVX100A last night and I noticed
that at 4.0 when I flicked on 6db the stop went to 5.6 so I guess that
I can see how maybe it would help you get a smaller stop if you wanted
but why is it always in play? If I use the zebras to get a stop, that's what I
want.

I like the HVX-200 zebra settings because I can set one for 70, which is
helpful to me, much more than the DVX100s which let me go only as low
as 80, which is far less helpful.

Thanks!
