Poor color from DVX100A

streckfus wrote on 10/7/2004, 3:24 AM
I recently did some test footage with the Panasonic DVX100A. I shot at night around a campfire using two people as the primary subjects. We previewed the images through the camera's viewfinders, and after experimenting with a basic lighting setup, we generated some great, rich footage.

Upon importing the video into Vegas, however, I found that the footage was nothing like the footage we previewed through the viewfinder. Instead of deep, rich colors (as was the case while shooting) we found that the footage, once imported into Vegas, was very drab. The richness and beauty of the image was simply not there...as if it had been completely flattened.

I messed around with a few plug-ins (color correction, a MovieLooks film filter, etc.) and made minor improvements on the image quality...but as of yet I've not been able to even come close to the image I thought I was capturing.

I haven't noticed this with daytime footage - is the problem related to the DVX100A & it's viewfinder (giving inaccurate images), or is there something I should be doing from a PC standpoint to capture the top-quality images that the camera seems to have recorded?

Any helpd would be appreciated.

How are you previewing from Vegas? Did you preview your footage on an NTSC?

PC an NTSC have very different gamma curve, so you must preview on an NTSC monitor to juge your image.

DVX100 has a somewhat blueish tint on the monitor but it is relatively accurate in term of contrast and saturation.

When you "capture" in Vegas, you are doing nothing more than transferring data from the tape to the hard drive and there is no way that Vegas is "flattening" the image, it isn't modifying the data in any way. And, yes, the only way to judge your footage is on a calibrated television monitor, not the PC monitor..

I have also niticed both on my DVX100a amd Sony TRV-350 D8 that the camera monitor the image always look bright and vivid. When i cature it into Vegas and watch the it as it captures the overall footage color is always darker amd more muted. This seems to be true whateversource I capure from. So would the footage look the same on a calibrated tv monitor as on the camera dispaly? When I output the final DVD though the color always looks acceptable more akin to the vivality to the original camera display. Ihave done some night shots around camping trailors and campfires with my DVX100a and the shots looked very good, no tweaking in Vegas needed.

This color flatness is even true of regular off-the-shelf consumer DV cams. I have a Canon ZR-60, and what I see in the viewfinder or LCD is never what I see on the screen in Vegas, but it does improve when it is viewed on a standard NTSC TV. This is why I have vegas set to preview on the television in the room I'm working in.

The setting of the camcorder LCD panel is also critical here. For example, if it is set too bright, and you adjust the camera exposure until the LCD image looks good, you will probably under expose the video. Also, monitoring the LCD in a dark environment, as mentioned in the first post, will definitely tend to make the image look bright.

Thanks for all the input. I realize that capturing the video via Firewire isn't changing it one bit, so I'm not concerned about "losing" any data or anything like that.

As most of you have pointed out, I need to use an external calibrated monitor while editing in Vegas, which is what I have not done. I've always used my Triniton PC monitor for video work, and up until now it seems to have worked just fine.

So I guess that's my main first step: setting up an external NTSC monitor for previewing (I'd planned on doing that eventually, anyway.)

New question, then: how does one "calibrate" the monitor to give accurate color/contrast/etc images? I don't imagine it's as simple as hooking up a DVD player and running a THX Optimizer from a Star Wars DVD! :)

Any suggestions on decently priced NTSC monitors that you've all had luck with?

Color Bars and how to use them

As far as what monitor to use, there is currently another thread here on the forum that is starting to discuss this very topic.
