Trying to get the best fireworks videos

OK, so let me preface this by saying I am a total n00b amateur weenie that is just trying to get the best video of fireworks he can. I am still using iMovie 5 and 6 (depending on what plug-ins I need and which ones will crash iMovie) but intend to move to FCE relatively soon.

Basically what I do is travel around the Northeast taping various amateur and professional fireworks shows. I mention amateur shows because they make up the bulk of what I tape, AND, since 1.4g/”Class C” fireworks tend to be smaller and not as bright the settings would be different than what you may use for your local town 4h of July show (depending on a number of factors including how much “B” vs “C” they use in their show)

I recently picked up a very nice DVX-100b outfit from here and have used it on 2 shoots, the first was a product demo shoot (something like 120 devices). I spent a fair amount of time the first night playing with settings trying to get it “dialed in” using the same pair of devices each time. The major issue is getting the deep blues and golds without blowing out the brighter reds and greens. By the end of the night I still wasn’t real satisfied with what I had, so sorta played with them so more the next night (which was the actual demo). By the second night I had settings that I was, if not happy with, at least thought didn’t suck.

Settings for this where:
Chroma Level: +4
Gamma: Cinelike
Knee: Auto
Matrix: Enriched
Progressive: 24P
All other settings 0 or Default

These where shot from about 700 feet away, which was good for the 1.4g stuff but not far enough for the 1.3g to get it from lift to break. For the demo videos people want to know “how high, how big, how long”, so they want it lift to break, preferably with some point of reference (or a grid, like these have).

Iris was “Open” and 6db in both cases. I have found that anything short of “open” and it just doesn’t get enough of what is happening. I am not sure why, logic (and Barry Greens book) tells me that 2.8-3.4 should be what I want. Always manual focus.

A pretty representative video of this first set of settings can be found here:

http://vimeo.com/11329792 &server=www.vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" /> http://vimeo.com/11329792 &server=www.vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="720" height="405"> .

This is in the smaller class of devices and is all blue and gold. I know this one pretty well (and, of course, saw it shot in person) and can tell you that the blues where “lost” pretty early after the break and the golds in this are whiter than they should be.

The second was a set of shows done by members of my club. This time I THINK I have the settings where I want them, but want to see what people that know what they are doing can tell me.

Settings for this where:
Detail Level: +4
V Detail Level: +4
Chroma Level: +4
Gamma: Cinelike V
Knee: Auto
Matrix: Cinelike
Progressive: 30P

All other settings 0 or Default

Any of the shows from the MAFF shoot on that page will work, but the best one would be this one:

http://vimeo.com/11181372&server=www.vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" /> http://vimeo.com/11181372&server=www.vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="720" height="405">

those gold willows in the NLPC splash screen and during the finale are all 1.3g/”Class B” so they are stronger than you would find in a 200 gram 1.4 device like in the first example, but there is plenty of 1.4 in that video and I have to say that they came through pretty good based on what I saw in-site.

The shows where shot across a 500’ front and people (at least the ones I do these for), again, like to see “lift to break. I was about 600’ back and it wasn’t far enough to get everything. Moreover, I am only a so-so (at best) cameraman, so I didn’t do as good a job as I liked getting everything.

So, if folks could give me some feedback on the following:

1) What do I want to look at for “tweaking” the settings for this. I expect I will basically need 2 or 3 scene files depending on what I am shooting. The second one looks pretty good to me but I am sure that it could be better. What I am more concerned with is bringing out the blues and golds on the smaller devices without blowing out the reds and greens (which tend to be stronger due to the composition used to produce the stars) or introducing to much noise.

2) What can I do better for composition. There are several places where even I can see I needed to be centered, etc, so those I am clear on. There are some that I was trying to get a firing position that I knew was there but either the shooter had problems with the firing system or some other technical problem so the scene is unbalanced, but is representative of what SHOULD have been going on.

Third, and stupid question: Is there some kind of grid overlay for the viewfinder/lcd that I can turn on and just can’t find?

And now an excuse – I love fireworks, and the fact is, in some of the places where there where composition issues (mostly centering related) it is because I was paying more attention to 700+ feet of lit up sky and marveling at how awesome it was and wishing to someday be as good at it as some of these guys than paying attention to my camera work. Excuses, excuses, I know, but I am trying…

Anyway, thanks for any pointers…
 
Don't open your iris all the way; that's setting it at f/1.6. Set your aperture based on the fireworks. You'll probably have it between 5.6 and 11. Shoot flat; in post it will be much more flexible because more color information will have been retained.

When I had it much past 3.4 I totally lost the blues and the golds where pretty weak. I had it at f8 and I was getting pretty much nothing of note except the reds and greens during testing the first night. It looked nothing like what I was seeing from the device on-screen or after I dumped it to my computer. This made sense to me, since I was letting less light in so I opened it up, however, from what I know about SLR and aperture in general (not a lot, but a little) my first impulse is to start at f8 and work from there, but as I said, at f8 I may as well have the lens cap on (not really, but you get the idea)

So, what is going on there? How can I have more color information if it's not really hitting the ccds? (or at least, it didn't look like it...)

Also, what is "Shoot Flat"?
 
Shooting flat means the camera is not enhancing saturation or contrast. Using the scene settings in the DVX is primarily for creating a look in camera. Someone else can jump in here, but I don't think you need to mess with any settings to capture everything you're describing.

I'm having trouble viewing the videos. If you can post a short clip or even a screen grab from each video, that would be helpful.

I believe your stated improvement via the second set of settings may have been due to shooting 30P instead of 24. Are you changing your shutter speeds?
 
Hey folks, shorry for the delay in response. I have been keeping the shutter at 1/60, but recently found an embarrassing amateur mistake that makes this entire thread a waste of bits, so...

I have a shoot coming up in a couple of weeks, it will be a mix of stuff with little or no "must have" stuff, so I am going to play around a bit with settings (starting out by shooting "flat" at 30p, 1/60 f8) and go from there.

Thanks all for the input, mods, feel free to close this thread, and I am sorry for wasting peoples time...
 
What was it? ND filter? You can tell me; I won't tell anyone.

No, I had that off on the cam..

<sigh> When I bought the cam it had a circ polarizer on it, I THOUGHT I had taken it off and put the UV filter on, hell, I even cleaned the dam thing just before shooting both times, noticed it "seemed loose" and was kinda dark, but it was after dark and I was in a hurry and seem to have incurred a fair amount of brain damage from, um, activities, as a youth. I have used the same (kind) of filter on my k1000 outfit for years, I should have known better. Dumb, stupid, amateur, idiotic thing to overlook.:furious3: at myself. Only thing stupider than this would be to have left the lens cap on...

So, I have "fixed" that problem and have a UV filter on it. That being said, I understand that this is the "standard" way to protect a lens from dust, scratches, and the like, but is there something else I can use, like an ND "Zero" or the like, something that will have NO effect on the colors coming through but still protect the lens?

(feel free to berate me for being a moron - I feel like one right now...)
 
Don't feel bad. Everyone forgets things. Stick around here and you'll read a lot of similar stories. Most folks suggest creating and using a check list.

A UV filter is fine as long as it's a B+W or another reputable brand.

It's a Tiffen so I should be fine (I think). I actully do what I call a "touch check" (put my hand on every item) before I load the gear into the car and keep EVERYTHING in the cam bag, but yea, I do need to do a check list, both for gear "loading" and cam settings, esp with this outfit, which is MUCH more advanced than the GS-320 I was using. I will do a search here for them but is there a tread you can recommend that would have examples I could go by, esp for the DVX-100b?
