I analyzed the first native D7000 clip I could find with MediaInfo and VideoSpec and here is the result: http://pastie.org/pastes/1222783 - The Framerate is now 23.976 - Video BitRate is 19 Mbps VBR - Chroma subsampling is 4:2:0 (it's no longer 4:2:2!) - Audio finally is 48 kHz / 16 bits

For pros and testers only! I don't think it's a JPEGsnoop problem but rather a problem with PapasArts MJPEG file therefore my request for a more normal 720p file. Sorry I don't have a GH1. Here are the quantisation tables of an unaltered GH1 according to JPEGsnoop. The smaller the numbers...

I havent seen any rates for news stringers I'm thinking i will get my new a1 and change my rates per story what do you all think would be a good rate for news footage per station per story.

Diffusion filter names and numbers seem to be standardized but I can't find more information about these different diffusion filters. What they exactly do and how they should be chosen. Has anybody a link for me that explains this, I tried but couldn't find anything. Thanks!

There's always some uncertainity and wishful thinking every time a new Nikon model with video comes out. Although I see that the data rate hasn't changed a bit I think that maybe somehow Nikon did a miracle in the new model. Wouldn't it be good to get hard facts? Well I found JPEGsnoop which...

slashcam.de linked today to a super easy to make DIY remote for Panasonic cameras. The PDF is in German but the images speak for themself. You need an 8 wire cable, plugs, some resistors, potentiometers, switches (Schalter) and push-buttons (Taster). Enjoy!

After reading this very positive review I became very interested in the HMC40 (or HMC41 in my part of the world). I own a Canon HF100 and I can't say that I'm overly impressed with it's image quality. It's good but not impressive. Now I found at least two postings where people actually prefer...

Slashcam.de reports today that the Nikon D3s has full manual control in video mode. This was confirmed to them by Nikon professional service. Just write to your local Nikon support to get this in your language. :Drogar-BigGrin(DBG) It's not even mentioned in the manual.

My 5DMKII with the EF 24-105 f4 kit lens and newest firmware is set to M mode and is mounted to a tripod. Arperture, shutter speed and ISO are set to f11, 1/50, 1250. The scene is perfectly exposed. But when I zoom in the exposure changes although the camera is in manual mode and the lighting...

A question to 5DMKII owners: I learned there is a Live View exposure simulation mode but this mode doesn't work when shooting video with full manual control. Only a so called "movie simulation mode" works. So in manual video mode with a Canon lens does the 5DMKII show the depth of field in the...

There's a rumor at nikonrumors.com about a successor of the really good D300. Basically its the same camera but with the addition of a movie mode that looks like that of the D90. Usually it's pointless to comment such a rumor but one can dream: The D300(s) is a pro camera and I would assume...

I don't know if this was discussed before but I found this Mac utility: http://laurent.ettouati.free.fr/english/ I analyzed one of my D90 AVI clips and it shows the better 422 chroma subsampling format instead of 420 which I thought it would be.

http://www.martincrespo.net/H30.mpg (29MB) If you need proof that this was shot with a D90 look at the nice stairsteps on the table edge at 00:13 which you won't notice unless you stop the clip. What do we learn: Make your movie fast paced and all the D90 flaws almost dissapear.
