Striation on Panning and Spinning - help?

Grazie wrote on 3/14/2003, 10:57 AM
Now that I can finally get my stuff onto tape and play back, I'm getting the above - It as if the picture is made up of strips and they are pulled apart. Do I need to resample the video or something? I get this on panning and spinning the clip.

Grazie

Make sure you are rendering at BEST quality.

D2 - I think I did. I'll go make sure - Thanks

Yup - "Full Resolution Rendering Quality - BEST" - "Deinterlace method - NONE" - "Motion Blur type - Gaussian" - Anything interesting there D2?

You going to pick up some artifacts no matter what you do when you rotate and object. How much depends on your source file and if or not you try to mask it adjusting curves, levels. etc.. <this is a recording)

What direct x are you running?

" .. <this is a recording) " Nice one BB - Is this your response from your Customer Service experience? Or are you bored having to say the same thing - time and time again . . hmmmm there's a parrallel here . . .

"How much depends on your source file and if or not you try to mask it adjusting curves, levels. etc.. " guess your invitation is to figure it out for myself - yeah?

Hmmm . . BB just a little more help here - "Excuse me? . . . you still on the phone . . . HELlOOooo . . " When you say "source file" you mean the captured DV - yeah? And in which case - what?

BB - thanks for the pointers - next time you're in London, I'll buy you a beer or two or three . . . . .

Grazie - [ DOah the phones gone dead . . . Helloooo . . helll o o . . ] ;-)

About your described problems:

The accumulated wisdom of asking the same thing about a dozen ways and times has yielded;

The effects are additive, you may not need all of the following:

1. Right Click the Clip and use either Switches or Properties and click "Reduce Interlace Flicker."

2. Add a bit of Gaussian Blur, I have used as little as .001 Right and Left. Increase as needed.

The more rotation, resizing, or various other treatments make the problem worse, resulting in a need for more blur.

Sorry, guys, but that is all I have. I certainly wish I had more.

If you have the time, try using DEINTERLACE-BLEND. May not help, but according to the help file, this comes into play when rendering effects.

Thanks Guys. UK here and your messages came in while I was in the land of Nod. Will try this morning.

Cheers

The effect you describe is typical when interlaced footage is scaled without first deinterlacing. If the footage is interlaced, make sure to set it's field order property to "lower first" (or upper first in certain cases) and not "none (progressive)". Then, make sure to preview and render at good or best quality. You can set the deinterlace method in the project properties, video.

SonicDennis, thanks for that. Project is set-up "Lower Field First". Render set at "Best". - Errmmm... might be a stupid question - Do I need to "Capture" the DV from the cammy to lower field first, if there is such a setting for capturing?

No Grazie, my 'this is a recording' attempt at humor was in reference to my frequent suggestion of using Color Curves.

BB - Keep it up! I'm getting close to losing my memory.

However, colour curves and the interlacing thing - how are they linked?

You still got the offer of a few beers here in London though.

The problem is that we have been doing these "insurance" protection things for a long time, now. They has been posted before. But the problem still remains even when we assure ourselves that these settings are still properly set.
