Hi,

I have a series of about 40 shots from a beach shoot after a typhoon. Some of the close ups have noise on them, the main problem I have is building a profile as there are very few instances of areas big and bland enough to grab a profile from within the 40 shots. Even the few skies I have are not a great help.

Even if I take profiles from other shots and gradually build up, the net result is neat Video appears unable to deal with separating sand from noise which results in a very plastic like look but there appears to be no getting around it with different settings. Has anyone also experienced this and found a solution at all?

Equipment used: Canon 6D, 100 ISO, 50 Shutter, 25 Fps, 2f - 8f on either 28mm or 35mm fixed lenses.

Any suggestions would be greatly received.

1. try to build as accurate noise profile as possible; if necessary, use a small area for initial analysis by Auto Profile, choose the most noisy area for that analysis; if necessary, additional fine-tune the profile using other areas;

2. disable the spatial filter (set the noise reduction amounts to 0% inside Neat Video window);

3. compensate the strength of noise reduction by increasing the temporal filter radius.

I hope this will allow to preserve the noise yet reduce enough noise.
