Noise? Really?

Believe it or not, they removed ctrl+shift+M, it was a collateral damage to removing the media encoder from the premiere main app, now you have to do it through media export. Set your timeline indicator to the frame you want to export, then go to export>media and then select targa or tiff, just make sure "export as sequence" option is unchecked. Then the usual explorer or finder window will pop up.
Before the latest update, after export>media, media encoder opened and one had to render queue single frame. Now they "fixed" it.
Frustrating.
I don't know what is the frame grab situation in cs5.

In CS5 there is a Export Frame button in both Source and Program panel. No default shortcut is assigned to it, but you can easily assign any shortcut to it in Keyboard Customization.

Direct export of any media is back in CS5 as well, no need to always go via AME when exporting media in CS5.

He never said improve the video quality, he said smooth out the noise.

One of the methods higher compression formats like WMV9, WVC1 achieve compression is by dropping information. Fine grain and noise are often smoothed over. Noise and grain are costly to encode and require a higher bitrate. Many encoders pre-process with denoising filters beforehand

That's exactly what I meant, thanks for pointing that out. I have found that in some dark, noisy clips, the encoding actually does look better at lower bitrates for this same reason. Not higher quality, just a lot smoother (which could also be done in post before the compression). This camera banks on the same technique for jamming all that info into 21mbps AVCHD. Try moving the camera around like crazy in 60p and you'll see the worst frames will have more of a natural looking blur than being blocky like HDV.
 
Hello? Anyone out there that is still listening and interested at all. I tried all of it. Everything you guys said. Kept going back to this thread reading and re-reading all of your comments and directions. It's worse.....not just a little bit worse....a lot worse. My image is total grain now. I tried scene files and knew right away just by looking a the flip out LCD that the tweaks made caused my image to be darker and the grain is just horrible. What to do. Also, when I last turned on the camera it was flashing ND1/4 though I had the ND set to off. Can anyone tell me what that's all about? Sorry guys but I'm trying. Haven't spent much time at all using the WFM so when I look at it, I'm sure what exactly it's telling me.
 
it means your image is overexposed and the computer in your hmc is advicing you to set your nd to on and preferably 1/4.

Total grain, are you shooting 60i or p? if so drs and or gain might be on which would explain the nd warning.

Shooting in 30p. I'm over the gain thing. I have gain shut down in every menu I can find. There is no gain, none. Drs is something I'm unsure about. I will check it. Overexposed or could it be too much light? I'm beginning to think that it may be the issue. I shot, or should I say accidently shot about 4 minutes of video the other day inside my home, middle of the day while I was walking around with the camera. I went through rooms that were lit with only daylight, others with just some ambient light through the blinds with only a table lamp and weak overhead lighting on. I have to say that while still somewhat grainy, it was the best image I've seen the camera shoot, ever. Now what I don't get is when I switched the camera ND filter to 1/4 the viewfinder became darker (makes sense) and when I viewed the material it went from bad to worse. It's as if when there is a lot of light it blows out which seems to me (not sure if I'm right or not) causes things like skin tones in particular to be very grainy. But if I pull exposure out by closing the iris the whole thing gets really grainy. Color saturation seems to be over the top too no matter what the scene file or setting. Nothing about what I shoot has looked natural I guess is the best way to say it. Any ideas?
 
OK, if it is not user error, and that may still be the case (no offence, but you do seem to be a bit new to this). Then I would say take the cam to an official panny dealer if possible and have them check it out. If they agree with you contact panasonic about warranty service.

Might be worth the call anyway. Someone at Panasonic will likely be able to troubleshoot with you over the phone.
 
If you're using the "auto" mode, you can set AGC off by changing the auto sw menu setting for AGC to 0.

If you're not using the "auto" mode then it's irrelevant, the camera does not have the capability to use automatic picture gain when the auto/manual switch is in "manual" mode.
 
I've had the same issue for a few months. It happens when the light is low, but the grain is definitely visible in the shadows on a bright, sunny day. The noise is clear in the LCD viewfinder and even more clear when the EVF DTL is on. Not sure if this is the same issue as shootit, but the more info that's floating around the better.
I've been shooting in CINE V with the MSTER PED at -20. I truly do not understand the noise unless it's just me looking for it. I'd love someone to post a screen shot of their footage in similar lighting conditions with the same scene file settings to help better get everyone on the same page.

ps. I don't want to come off like I'm hijacking the thread, but I'm sure shootit and I would love some peace of mind on this one.

pps. Everything was manual and every gain function is off. (I owned a DVX before and never once had noise problems. I actually found the picture was cleaner, even though I know that comment will come back to haunt me) I should also note that I have done the menu reset twice (no change) and ABB (again, no difference) and no difference when white balancing.

If you can say a DVX is cleaner than an HMC150, then something is just way wrong. The HMC150 is dramatically, incredibly cleaner than the DVX ever was (including the DVX100B, the newer, lower-noise version).

Here's a link to a post I did with some low-light samples, showing that the HMC150 is just a lot cleaner, even when it's at higher gain.

I thought so. I did have the DVX100b and was very pleased with it, aside from the lack of HD. I have to say that I am underwhelmed by the hmc150 I have (but I bought it used in case that would matter). I saw videos by Joshua Herron and others that got me pysched purely at the resolution of the images, an although I am nowhere near as talented or skilled, I feel that the noisy and less than stellar resolutions still prevail when I've done almost every thing I can do. I'd be lying if I said it didn't get me down some days.
The only way to avoid the grain (that I have found personally on my camera) seems to be to expose the image almost to the point of overexposure which of course makes you lose definition in the more highlighted areas of the shot.
 
Again what are you viewing your videos on? Pleas say you are not judging noise by way of a LCD monitor and your computer? My Dell LCD is crazy noisy even with commercial DVDS. They look pretty bad especially from normal chair viewing distance. Also are you transcoding your footage? This could possibly add noise as well. Best is to go HDMI to a HDTV and be sure to set up your TV correctly before viewing. You may want to turn sharpness down on the TV.
 
We need screenshots to be of any help.

Not to be mean, but if you are unsure of DRS and the WFM, you really need to completely read the entire manual carefully and then tweak each adjustment to see what it does and how it affects the image. You really need to hook up the camera to a good/calibrated HDTV via the HDMI, point the camera for some appropriate test shots (I know, tough to impossible for many folks) and see exactly how the camera responds to each setting.

And again, post some screenshots off your NLE.

These are all such good and critical points, they cant be overstated.

Side note: Also, when I check DVD playback on projects before delivery, I use three DVD players. Between the three I see and (and hear) a big difference between the players.
 
this thread has been going on for a while now but there is still no screenshot or test footage so we can see the issue you are having..........despite repeated requests fot it!

please post something so we can actually see what the problem is you are experiencing! :)

cheers,

Hi, I've been lurking in dvxuser for some time now but after reading this thread I finally have something to post.

I have a raw MTS here, and a snaphot here, shot with the HMC150 through a Brevis with a Nikon 50mm F1.8. I made it quite dark to make the noise more obvious. I used Barry's low noise settings. Knowing the HMC150 shoots at ISO 500, I'm asking too much if want a ISO 100 noise image. But hearing people touting the camera for low noise, I must say I'm quite taken aback after looking at the video myself when I got the camera. On the bright side, the noise might pass off as film grain (or at least I hope so). I'm not sure if I have the correct noise level for an HMC150, or if this amount of noise is the norm with video cameras like this, because I'm used to clean, low ISO pictures from my DSLR.

I hope some more seasoned shooters might care to advise?

well by making it "more dark" I'm guessing you underexposed? That'd bring on the noise so that doesn't make much sense. Also was your brevis working correctly? If the GG isn't vibrating correctly my guess is a noisy image. Take the brevis off And shoot a properly exposed image and judge the noise from there.
 
I've managed to improve the images. Sorry I've not posted screen caps. I have looked at others that have been posted on here to demonstrate how "good" the camera is. Frankly mine are just as good and in some cases better. It could be my expectations coming to HD were too high. The only thing that is burning my brain is with all the compression with AVCHD I wonder what an HDV cameras image would look like.
