Anyway to sharpen image in VV3

Someone in another post said their might be a way to sharpen captured VHS footage in VV3 (when I say "sharpen," I mean the kind of sharpening you can do to digital photos in Photoshop, for example, essentially edge enhancement). Is there a way? I searched the VV3 manual, but didn't get any hits for "sharpen."

Thanks

You might try the "Sharpen" FX...

Check the manual for Video FX

Worth a shot?

Last time I tried "sharpen" it added artifacts

Try the UNSHARPEN filter also.

In still photography, a little sharpening goes a long way. I took a look at the VV sharpening last night, and from looking at the plug-in animations, I'd say that even the lowest of the three settings would be considered oversharpening for a still photo. I would ramp the sharpening down even below that. I may do some tests this weekend.

My opinion and all that... most of the activity I've seen with folks captureing VHS has been centered around virtual dub. They'd developed quite a few filters that are fairly fast just for those challenges.

While they do have various sharpening filters for v/dub, I will make a guess that what you might need to do instead is get rid of the background noise that makes your image seem less then sharp -- something that the v/dub filters really are good at. The overal effect is one of increasing sharpness, but without sharpening (increasing contrast) the artifacts that are already there to make them more noticeable.

Though VV3 is excellent in so many ways, I think you'll also find that v/dub is MUCH faster when it comes to resizing or removing noise.

mikki, thanks for your suggestions. I capturing via firewire using my DV camera's analog pass-through feature. Will Vdub support that?

Thanks,

Why don't you do it manually by using the slider instead of using the rough presets?

That's what I meant by ramping it down -- using the light button setting as a starting point.

I've had fairly good success with the unsharp Mask using between 80-150 for amount, 12-25 on the radius leaving threshold at zero. The presets are a bit much for most videos. Drag the filter to the timeline to effect a single event or drag to the preview window to effect the entire video. Your mileage will vary depending on source file.
