No ghosting at all. The noise reduction is off.

Though it doesn't really apply in this discussion I've noticed that 24f results in a much cleaner image, i.e. less noise and fewer artifacts, compared to 60i and 30p. I don't have anything other than my observations to back that up. I can't help but think its more efficiently using the bandwidth afforded by the codec because there are fewer frames.

Thanks Joel, then I will give the preset a try. If it is effective I sure wished I'd used it last weekend during a candle lit only reception I had to film :)

About 25f (or 24f which is basically the same format) producing less noise I can only say that a test I did some time ago in a very dark area exporting frames from both 50i and 25f and I saw no difference at all. Both were equally noise rich, whatever setting I used. Also what I often read here that 25f is supposedly a bit more light sensitive then 50i is something that I could not see. 50i and 25f looked exactly the same to me in very low light conditions.

Hi Noa. Definitely you should give PFVision a try. It is great for indoor shots where the lighting is a bit subdued. e.g. where normally you would start to get a noisy, desaturated image, this preset gives very natural results.

Haven't tried it in candlelight though, looking forward to hear your assessment.

I read the meassages in the link that was given in this topic about the preset and one of the users said that he had used the preset a couple of times at weddings but it had a negative effect on the automatic focussing ability of the camera. It appearantly also caused the image to appear "soft" and out of focus. Anyone more experience about this?

Increasing CORING up to 9 must produce softness in low light conditions. Try this preset.

Hi Noa. Automatic focussing is definitely affected by low light levels, but I didn't notice if this preset made it worse.

Have you tried it yet?

Hi Artur,

The slight softening caused by increasing the coring is made up for with the higher sharpening level, at least to my eyes. The effect is an image that appears sharp but with less noise. I've looked at enlarged images shot with high coring with high sharpening and low coring with standard sharpening. I prefer the high COR/high SHP setting - the images appear sharp but lose the overly defined edges and the noise in the shadows is reduced.

"[COR] Coring [–9...+9]. Adjusts appearance and level of noise on darker areas.
• Increasing will lower the level of noise, but makes a softer picture.
• Decreasing will lead to more visible noise.
It is recommended to tune this option any time you are using gain.
Can be especially helpful, when shooting densely detailed objects in low light conditions. Also
helps to eliminate "stairstepping" that can appear along diagonal lines.:"

I shoot at 24fps / 1/24th / and 6db at the reception with two remote control low-wattage lights on 13' stands and get great results.

The only filter setting that will darken the image iis if you inadvertently have the neutral density filter switch on.

Hi . in your sample test of the PFvision preset - EventVideographer.com ~ XHA1 PRESETS
you show the PFvision preset and a sample of your settings- your setts looked better - what were they?
Thanks G

My original preset was the popular TRUCOLOR. Keep in mind that those stills of the presets I posted were done with the camera set on manual so that there was no automatic adjustment to the iris or shutter speed when I changed the preset. With the pfvision preset I feel like I'm about a stop brighter than trucolor, but I didn't stop down for the example shots. I hope that makes sense - I'm just trying to explain why pfvision may look washed out. Its overexposed.

here's a link of some candle light test footage I did a while back using PFVISION.

Settings are on the link.

hope this helps

Joel - I was curious about what lights you were using.

Thanks,
