JVC back in the game?

JVC back in the game?

Maybe that's not the fairest title for this post.. The HD250U is a sweet camera but it's a bit of a niche ENG thing and isn't really a direct competitor of the Panasonic HVX200A or Sony EX1. When I say "back in the game", I'm referring to the ongoing competition between Sony and Panasonic for the hearts and minds of the digital filmmaking community. The small camera devotees - the dvxuser.com crowd. The users that really brought lens adapters for small cameras into the mainstream. This area of the market really has been a Sony vs. Panasonic game for the longest time but JVC recently made a few announcements that might put an end to that.

These new offerings from JVC are the shoulder-mounted GY-HM700 and the handheld GY-HM100U. These cameras both have an impressive list of features but the point that grabs me first is the lens feature of the HM700 – similar to the upcoming Panasonic HPX300 – it uses a 1/3” B4 mount which can also be adapted for use with 1/2” and 2/3” video lenses.  That’s fine and dandy but JVC also makes the HZ-CA13U Optical PL Adapter, which works beautifully with 16mm film optics. A lightweight, shoulder-mounted camera that you can put just about any lens on without a massive, cumbersome adapter = !!!!!

The HM700 and 100's major departure from to the older JVC ProHD cameras is that they both shoot Full Raster 1080p Final Cut Pro files directly to common SD cards. In the past the argument against JVC is that its version of HDV hasn’t been well supported in the NLE. That said, the decision to eliminate wrapped file formats in favor of something that can be brought into FCP immediately without any conversion seems like a good one. The new 35mbps codec IS proprietary but it’s based on MPEG2 Long GOP, which at this point is the most universally accepted HD compression. According to JVC’s literature, the files are drag and drop directly into FCP6 where they are ready to edit without any unwrapping or transcoding. The exact same files can also be recorded to card in ISO Base Media folder/file architecture ensuring compatibility with PC-based NLE’s. In addition, the HM700 can optionally record to SxS cards with add-on hardware making it even more versatile.

I’ve always liked the functionality and ergonomics of JVC’s cameras but have never really been blown away by image quality. I haven’t seen anything from these two yet but I have high hopes for them. Sony and Panasonic have dominated the small and medium sized camcorder competition for so long that it’s refreshing to see someone else put out a product that can potentially hold their own against the more widely used models.

Digital Motion Picture Sweeps The Oscars

Digital Motion Picture Sweeps The Oscars

The lovely Slumdog Millionaire found the same success at The Oscars as it did at The Bafta's and Golden Globes, taking home the top honors - Best Picture, Best Director, Best Adapted Screenplay, and Best Cinematography. This is the first (mostly) digitally acquired feature film in the history of The Oscars to win Best Picture and Best Cinematography. Not bad for a small independent shot with a relatively new and radically different digital cinema camera. I think this is the greatest possible success for next generation digital cinema companies like RED and Silicon Imaging - makers of the SI-2K Mini with which Slumdog was mostly photographed with. It is a massive confirmation that film isn't the end all be all in quality and that digital imaging is not going to get in the way of audiences recognizing a wonderful story. It's very cool to be working in the business during this paradigm shift. There is a lot of great energy and excitement as the tools of the trade are becoming more accessible and affordable to people with big ideas. When a film like Slumdog Millionaire can win the highest American industry accolades it should give independents and people working outside the mainstream a lot of hope that their work can find its audience and earn worldwide recognition.

Regarding the film's cinematography; when I first saw the film I noticed what I thought was sensor noise in the game show scenes. Since then, I've heard from numerous folks that this was an intentional look done in the grading process to match the grain of some other materials (mostly Day Ext's) originating on film. I also read Anthony Dod Mantle saying that the SI-2K images picked up a lot of noise as they traveled through the post pipeline. I'm still looking into this but if it's the case that it was done in the grade, the effect might have been pushed a little too hard. Don't get me wrong, it didn't wreck the scenes but one of the points of this blog is to evaluate the quality of digital images and if there are noticeable issues in a widely seen film such as this, they will be commented on. Other than that, I think what's really strong about the film's cinematography are the great angles and fluid movement that are only possible with a tiny, discrete camera like the SI-2K. The film's camera language has this great "fly on the wall" observational quality that I think is the most successful aspect of its storytelling.

Another aspect of the cinematography that I really like is the slightly rough around the edges, almost handmade quality of the images. In an era where "perfection" is the norm in motion pictures, it's really refreshing to see something so different than what we're used to seeing be so successful. It just goes to show you at the end of the day audiences want a great story more than they want perfect hair and makeup and perfectly consistent exposures and prefect camera moves. I don't want my movies to look like they were made by highly skilled robots. I want the human touch and Slumdog has it!

Go read this on ProLost >>> I failed to mention the film's very effective use of 12fps material. Stu has some great points about cinematic motion and some current industry trends that are a little disheartening.

MIRED SHIFTS FOR COLOR CORRECTION GEL:

MIRED's are used for calculating color temperature conversions. The math always gets lost in my head so I often use Lee's online MIRED calculator >>>

Here's a link to Rosco's Filter Facts PDF that has a good explanation of the Mired Formula and how to use it >>>

TO INCREASE KELVIN:
CTB  (Color Temperature Blue)-131 MIRED (Converts 3200k to 5500k or 2900k to 5200k)
1/2 CTB -68 MIRED (Converts 3200k to 4100k or 2900k to 3800k)
1/4 CTB -30 MIRED (Converts 3200k to 3500k or 2900k to 3200k)
1/8 CTB -12 MIRED (Converts 3200k to 3300k or 2900k to 3000k)
