HVX Frame Rates Slow-Moooo

I understand the HVX will be able to do frame rates of 60fps...which is awesome.
Would there be some way of getting it even faster....especially that it is going to P2 and is not constrained by tape recording speeds.

Thanx
 
Probably not in HVX200.

The Ikegami Editcam will do 120Fps if you need it in a camcorder.

I've been looking at this FireWire camera:

Just something to keep in mind (from someone who's worked with these kinds of cameras before) is that the given resolution is not the color output resolution. Know that these are monochrome cameras with a color filter array (a CFA, sometimes referred to in general as "Bayer" pattern arrays), which means that the final color image is interpolated at approximately a 2x loss in spatial resolution.

Of course, the method of interpolation affects the final quality quite a bit, but the best ones are the subject of patents and the like. Nearly every single digital camera on the market, both still and video, employ these techniques. If you're interested in this, feel free to hit me up for more. :)
 
Obviously. JVC actually had a camcorder that could overcrank back in 2001. The way it worked was by recording only part of the frame, as I recall, but at the higher speed. So, for example, you could have a tall skinny picture, a widescreen picture, or a half-resolution 4:3 centered frame and effectively get real slow motion out of a MiniDV camcorder. Pretty neat idea at the time. Perhaps Panasonic could implement something like this in the HVX200. Not likely at this time, though. The 60Fps limitation, if you will, is part of the 720p60 standard.. To do anything else would be, for all intents and purposes, a non-ATSC standard.. But, I do personally see the value in framerates above 60Fps, I just don't think it will be on this camera at this time.. That JVC camera was the GR-DVL9800 if any of the tech heads wish to read more about it. Hope this helps.

I am extremely stoked about the idea that one can go up to 60 fps with the HVX, or any framerate in-between, at any resolution that the camera supports.

Check Mel Gibson's commentary on Braveheart for some great cinematic tips. Specifically, go to the scene where he sees his beloved for the first time at the market after they are all grown up. Mel talks about how he learned to overcrank the camera a bit when shooting female leads, because it just imparts that magical feeling to the footage. He specifically mentions frame rates of 30, up to 35 fps. You can see exactly what he is talking about in that scene. I remember thinking when I first heard that, 'oh man. I'm never going to be able to afford a camera that can do that!'

This is going to be a great tool for the likes of me.
 
i remember that. i was actually really impressed with the braveheart commentary. he also talks about an editing trick where in an action scene of someone swinging a sword or something, he would take out one or two frames to just before the sword made contact so that the swing would have more of a punch. i've used it a couple times and it works pretty well. (kind of off topic...sorry)
 
Hey off topic is good.
I will check out the BraveHeart info. I guess my next option is 60fps and then maybe Twixtor for more FPS's...in software land.

I'm also in a deliema as I need the HVX camera NOW for a possible 2 year gig.
Will probably do the wrong thing like buy the Z-1 and then sell it once the HVX is here and proven......damn...Jan.

I re-watched that commentary... my girlfriend saw me watching it and called me a slut. Haha!

Anyway, Mel's commentary that is interesting to this topic is through most of scene 6, which is at least 12 minutes long. He says at one point that shooting beautiful women at 48 fps gives them that extra something.

Pais,

If I'm correct, are you saying that camera's with that kind of high frame rate don't actually spit with color? :huh:

Heh, a loss of color quality is nothing new to DV users. In fact a 2x loss in color inofrmation is a step up. :laugh:

Sorry, I didn't mean to take the thread off-topic with all that mumbo-jumbo ... I just got excited that someone brought up this topic again, because I spent a lot of time going down that path. :thumbsup:

Like I mentioned before, the color is reconstructed in the same way as in nearly every digital still or video camera out there (to my knowledge). It works, but essentially, you won't technically get one raw, full-color RGB value at each pixel of the sensor's advertised resolution. That was just what I wanted to point out.
 
sorry to resurrect this topic again, but I was reading through studio magazine and there is an article from Barry Green on the HVX200. Now, I come to these forums multiple times a day and read pretty much everything that gets posted about this camera, I was at the NAB DVXUser presentation, etc, etc. but I never noticed this before:

"When shooting high-definition video at 720p, it can record at 24P, 30P, and 60P, but also at a wide variety of frame rates in-between. This means the camera is capable of recording superb frame-accurate film-style slow motion, better slow-mo than any other video camera on the market (excepting only the VariCam)!"

This is from the studio article, but something similar is posted in the article on the HVX200 article on this website. Anyway...so this means, I'll have access to native in camera frame rates other than 24, 30 and 60? I can not believe this camera is still getting cooler (well, at least my perception of it :cheesy: )
 
By the way, I don't suppose we'll know exactly all the possible framerates it can do until there's more documentation on the camera, right? Or is it literally every possible framerate between 4 (or whatever the lowest is) up to 60?
 
We don't know yet. All we know for sure is that the slowest is 4, and the fastest is 60, and that there will be frame rates inbetween.

We are pretty much using a slightly more expensive version of this for cinematic applications on one of my other companies www.purposelabs.com . They are made for industrial uses, but most can shoot progressive 24p and as long as you use a good lens it looks very good, as you can see by some of the test footage on purposelabs. My avatar is actually a pull of a frame from the high speed camera.
 
Hm wow Jarred.. the clips on purposelabs are really great. They really kick in! :-))
Any insight on what kind of cam you guys are using? And what's even more interesting.. how do you record the data - uncompressed? To what? ;)
