It helps to reduce flicker when 2 interlace fields don't exactly match. It adds a vertical blur (a kind of mild smear) to compensate for this problem and reduces the flicker in the process. It's a very subtle effect and you may only see the flicker effect rather than it increasing or decreasing the picture quality.

Ya think? :D
 
Re: Bird Grabs

So when would 2 interlace fields notmatch?

I shoot at thick for a more filmic (exposure look) setting.  Not that I'm blindly trying to make things look film *shooting 24p without purpose and blindly letterboxing because it's movie like" but i want to try and simulate some of the 250D stock films.  Unbalanced day light stock film has a higher color temperature giving things a blueish tint when shot without the proper 83 filter and I want to try and get that look.

So the v detail further adds to this blur?  Just trying to milk you for all your information disjecta because you are so helpful and cuz you rock.

You have a strange sense of humor, enterdcable, I like that about you   :D

Two interlace fields would not match (although they never really do, ever), for instance, when you move the camera in any way. One field will record an instance and then, 1/60th of a second later, the next field will record another instance of the scene. Because the camera has moved by that infinitismal amount and a TV is essentially trying to create one picture out of two fields, there will be a slightly misregistration which is usually in the form of jagged lines, etc.

There are all types of combinations of settings that deal with interlace flicker problems and this particular setting (V Detail) is one I would use if shooting in thin or mid mode. Shooting in thick mode and using V Detail, I think, would be overkill and you would start to see image degradation in the form of an overall fuzziness in your entire image. In fact, thick mode compensates so much for this effect that it may cancel any effect V Detail may have at all.

If you combine the mid or thin setting with the V Detail setting, you will potentially reduce interlace flicker while getting a little more resolution than shooting with Thick mode.

I have not done any critical tests on this but the theory of it seems sound to me. I'm sure Barry can expound on this and maybe even prove me wrong....
 
Re: Bird Grabs

;D ;D ;D Disjecta, run for president and you got my vote ;D ;D ;D

I learned so much once again. Though my questions are never too clear and often stupid (yes there are stupid questions because there are stupid people) you seem to understand what I am trying to figure out.

I've been shooting like v detail -3 and thick... no good huh?

I thought thick mode was recommended if you plaln on shooting 24-p with no real plans of theatrical release. Thin would be for 24pa and to upres it later or something.... am I incorrect in this assumption (assumptions make an ass out of me and u- every hear that saying?)

Anyways. I should start cutting checks and making it out to: Professor Disjecta at DVXUSERSCHOOL.com. Cheers. Do you charge by the hour or by the ag aggravation ::) .
 
Re: Bird Grabs

And not to mean to play pirates on your thread, but what's your two bit on your century optics teleconverter? Was thinking about using this to shallow depth of field without getting the 35 mini adaptor. (because after getting the adaptor, then I would have to get the lens). This might be a solution for now. Besides why would I buy high speed lens for a mini dv camera... even if it is the xlr 2? Some lens could cost more the dvx.

Anyways, a good question now:

1. How far away were you from the woodpecker in the pics?

That's all I got. Now Stupid questions:

1. Do you have any other lens/zoom control toys?! ;D

2. TIffen 4 x4 s fit in FM 500?
 
Re: Bird Grabs

I was about maybe 15-20 feet away from that sucker.

I just love the teleconverter and I find that I have a lot more control over narrow depth of field. It is most definitely enchanced with this lens and, in the proper hands, can be made to look very close to some of the same effects of the mini35.

Of course it all depends on what you are shooting. It works well for me because my subjects are almost always just out of reach.

If you are shooting with actual humans, however, the distance you have to put between your talent and the camera lens could be a problem, or not.... just a consideration.

For once in a lifetime type shots where my subject is way out of reach, I opt for a lot of glass. I attach a step down ring (72mm-58mm) to the dvx and attach a Century Optics 2x that I had for my Sony DSR-250. Then I mount the Century 1.6x in front of that and make sure the whole thing is supported on a rod system sandwiched between the camera and my CAVISION 4x4 bellows mattebox. This gives me a focal length of 144mm, as opposed to the 72mm I can achieve with just the 1.6x

This is not the best solution because there is significant softening around the edges and for that very reason, your framing is limited to the center of the lens and I hate that kind of limitation. This solution is a rare one for me as the 1.6x usually provides me with all I need.

The day I got the 1.6x was a thrill and I still feel that way about it. Coupled with some ND filters, you can really approximate that film camera depth of field illusion.
 
Re: Bird Grabs

I'm DROOLING. I'm DROOLING <in wicked witch of the west voice> No, no, that was just my heart farting with envy.
 
Re: Bird Grabs

Hahaha, I just thought about selling the mic, getting the converter and some filters and just shoot a silent movie ;D.
 
Re: Bird Grabs

disjecta, since you're the offical DVX bird man I have a question for you?

This is off subject but again its not.

What is a good book showing the different types of birds?
 
Re: Bird Grabs

Gary, there are all types of field guides out there but I tend to gravitate towards the ones that are more specific to my area. Looks like you live in California so I'd recommend Sibley's guide to you:

http://www.amazon.com/exec/obidos/A...31/sr=2-3/ref=pd_ka_b_2_3/102-7202744-5884905

That's a great starting point. Also, if you go into your local bookstore and go to the local interest area, they will usually have birding books specific to your area.
 
Re: Bird Grabs

Love the shot of the pileated woodpecker. Those are impressive birds. I love their call--almost something you'd hear in a jungle. Last fall I saw one working on a dead tree, and *shards* of wood were flying everywhere. (No camera nearby :'(). When I got home from work there was a huge hole in the tree with a great big pile of wood on the ground. Talk about missing once-in-a-lifetime shots!
 
Re: Bird Grabs

Thanks for the tip.  I guess I have to change my information.  I now live in Missouri.

Still trying to buy a farm so I can turn it into a studio.
 
Re: Bird Grabs

I want a studio too. All of us on this site should donate 20 bucks each buy out a large part of wyoming or kansas or something and do our own sundance. ;D
 
Re: Bird Grabs

with the teleconverter, can you use the fm 500 mattebox? i was hoping to use it in concert with some filters...
