HVX200 and noise

Hi. I am new to this forum and I am having an issue with tons of noise when I shoot anything with my HVX200. I own 2 hvx200's and get the same results with both. I have read many of the "noise" posts here and on the net and cannot seem to come to any consensus about how to fix the problem.

Other footage that I have seen that was shot with my exact camera is gorgeous so I know the camera is capable.

Now I already know that the HVX is not a great"low light" camera. However, I am trying to shoot outdoors in the middle of the day with plenty of light and still see considerable noise. What am I doing wrong?

I shot an interview for a client with 3 point lighting, plenty of light on the subjects face (not clipped) and a nicely lit fireplace in the background and guess what........NOISE!! I am pulling my hair out on this!

I also know that there is a great plug-in called NeatImage and will use it when I need to to clean up footage that is unacceptable.

Yeah, I guess I could spend the next 6 months testing and making mistakes and reading the manual for the 100th time and so on however is there anyone that could give me some real world common practice answers. I just want to start shooting!! I have owned this camera now for about 5 months and have not been able to just shoot something creative yet. Please help if you can!

I will post stills and video soon so you can see the problem I am having. Thanks
 
Mark,

This has been discussed to death here recently and there are active threads on this list, so search is your friend.

You will need to give more info:

How are you judging noise? If it is on your CPU monitor within your editor, the results will be poor and misleading.

Have you explored different scene files? You can tweek the look and reduce noise.

If you are using any gain, that will create noise.

Yes, discussed to death but with no real world answers. I am a working professional in the industry and understand gain, noise threshold, etc. i understand light and how to use it. However, I am NOT an expert with the HVX200 and thought rather than "experimenting" over the next 6 months, I could find someone to help me bypass all of the gobblygoop and get down to business so that I can be creative and go make a living.

I am judging noise by the way the picture looks like in complete daylight at friggin 2:00pm in the afternoon with blue sunny skies and plenty of light. My assumption is that in that particular situation, noise signal should be negligible to none as it is with every other camera I have used.

I just shot an interview with Trump in New York indoors. We used a different camera Sony Z1u, 650 watt keylight w/softbox and CTO gel, minimal ambient light, at 1080i and you know what, NO FRIGGIN NOISE!!

Same interview situation with the HVX200 and ther is LOTSA NOISE!!

I know it has to be a setting of some sort. Please if anyone can help me bypass all of the crap that I will have to go through with trial and error, it would greatly be appreciated. Thanks
 
Post your current scene file settings for review. The answer you are looking for will likely come once we know how you have your camera set up. Otherwise it's like shooting fish in a barrel.

I have been shooting with the default scene files. I read a post (possibly yours) and I am gonna try with the settings that were recommended. Thanks for the reply
 
Mark,

First of all, recognize that Panny HVX-HPX cams are not the best cams for straight interlaced TV work. They will shine in more cinematic progressive shooting situations, so your needs and shooting style will determine how happy you will be with this cam.

You didn't mention much about your cam settings so it will be pretty difficult to suggest a magic bullet. You did mentioned shooting interlaced on the Sony which is where the Sony will shine. Interlaced isn't the forte of the HVX-HPX. The original HVX isn't as sharp and has more noise than the newer "a" version. Having said that, the sweet spot for a HVX is going to be progressive 720/24 or 720/30. If you really like the Sony interlaced look, you might never be very happy with the HVX. The HVX is much less clinical and more organic than the Sony. Color is where the HVX will shine with a very pleasing saturation. The HDV codec of the Sony is inferior to DVCPro-HD in both color and motion using progressive.

If you haven't researched scene files and how to tweek them there are two good sources. The first is the HVX-HPX book by Barry Green. The other is a white paper published on the Panasonic Pass site. Beware, the Pass site is pretty goofy, but there is a lot of good stuff there.

I don't know the source on this HPX scene file suggestion, but here is a "Low Noise" scene file recipe. Your HVX settings may need a little adjustment due to the differences in the cams. I'm not so sure I am enthused about the low detail level, but that is me, I prefer a somewhat sharper image which does magnify noise.

Grant
