Cinelike, Cinelike_D, Cinelike_v

Hey guys, I am new to the dvx and dvxuser.com. I absolutely love this website. I have spent the last 6 hours reading some very informative threads. I have a couple of questions....does anyone know of a book that is specifically written around the DVX-100a and 24p technology. I would like some reference material. Of course the users manual that cam with my dvx-100a is not very specific or informative.


Also, can somebody tell me the gamma differences between Cinelike, Cinelike_D and Cinelike_V? I know that Cinelike_D has more dynamic range...however I am unsure on the ideal situations for using these 3 cinesettings and what the specific differences are. For film look, which of these should I generally use? or does is vary?

One last question, what is V Detail Frequency? Thin? Mid? Thick? What determines which setting should be applied?



Any information would be greatly appreciated. Thanks! I am so excited that I found this resource.

I'm currently finishing up a book/DVD combo that will cover everything you're asking for. Should be available by the end of this month, if all goes well. Keep an eye towards DVXUSER.COM for an availability announcement. :)
 
Re: Cinelike, Cinelike_D, Cinelike_v

Looking forward to your book/dvd combo Barry.

As a precursor to your book, do you think you can share a little info here on what the difference is technically between cine, cine_d, and cine_v? Not having had the time to do tests with waveform monitor i was hoping you or someone else might have some insights to share.

Thanks!
 
Re: Cinelike, Cinelike_D, Cinelike_v

I haven't tested it as much as I'd like yet. Adam Wilt did some comparison shots. Basically cinegamma is the "regular" cinegamma, which shifts the upper range of exposure values down to provide a *lot* more latitude in the upper half of the exposure range. It softens contrast substantially and gives you a lot more exposure detail in the highlights.

cine_d and cine_v are basically variations on the original. For one thing, both incorporate knee protection against blowouts, something the original CineGamma does not do. In CineGamma you get direct unmodified image data straight up to 110 IRE, at which point the image blows out to ugliness. But up until 110, you're getting the straightline image. The new gammas offer a rolloff at the top to help prevent overexposure. With the original CineGamma, it's up to you to prevent overexposure.

Cine_d is tweaked to provide even more dynamic range, but I believe it's quite a bit noisier than regular cinegamma -- more testing is necessary. Cine_v is contrastier, which at first glance appears to be the opposite of cine_d. As in, cinegamma provides great latitude but flat contrast (i.e., using CineGamma can make it look like you laid a sheet of translucent gray over your video). Cine_d attempts to extract even more latitude, with obviously a resultant further flattening of the contrast. Cine_v punches up the contrast, which means you'll have less dynamic range.

But again, this is just from playing around, not from extensive study yet. I've learned so much about the DVX100 by testing the living daylights out of it, but I haven't been able to spend that much time with the 100A yet.

Thanks for the info, Barry...Please let us all know when your resource is available! Can't wait.
 
Re: Cinelike, Cinelike_D, Cinelike_v

Isn't the deal with something like Cinelike_D that you have a flatter image with all the video info properly exposed and you can color correct to bring out contrast in post?
