First frame and last frame darker then rest of shot?

Post by Neliskens » Fri May 08, 2009 12:32 pm

If I put the effect on a shot, a lot of times (almost all the time) the first frame and the last frame are darker then the rest of the video. If I put the Temporal Filter Radius to 0 and render it's gone, what is the deal with that?

We haven't seen such an effect. Could you e-mail (to support [at] neatvideo.com) a small sample project (with a short clip) that would demonstrate this effect after rendering the clip? We would directly reproduce the effect and check what exactly is going on.

Thank you,

Ok, I will do that. I am rendering something else now and will get back on it.

Could you e-mail us a small sample project (the complete FCP project with a short clip)? We would open the project and render it to directly reproduce the effect. It is important to be able to reproduce the effect, not just see the final result.

Thank you,

How do I send the FCP Project. I have this clip it in a new sequence timeline and then?

Please save the project to the folder where you keep the clip file. Then compress that folder into an archive (like ZIP) and send the archive file by e-mail.

Please make sure you build an accurate noise profile after adding Neat Video to the clip. With an inaccurate noise profile, darkening of the edge frames is possible. As soon as the profile is right, darkening should disappear. The key is build an accurate noise profile for your clip.

Hope this helps,

How do you build an accurate noise profile I've done it like five times and I still get the same dark first and last frame, thanks

You have to select a suitable area for Auto Profile, that's the key. Such an area should contain visible noise and no real details. If you are not sure please e-mail (to support) a sample project with a short clip and NV added to it with a noise profile you have built. We will check if the profile is good and whether the effect is generally reproducable on our computers. If it is then we will try to find a solution.

Thank you,
