Using Sharpen filters

OldTimer wrote on 10/25/2003, 4:14 AM
I'm currently editing some old video that was recorded on VHS. The content, color etc all seems to be OK. I just notice that the film doesn't look too sharp. Is it just a case of taking a scene copying it a a few times & rendering it out several time using differant settings of the filter so that you can judge it on a large TV? Is there any rule of thumb for just when & how much you should use these filters? Would you ever apply the filter to a entire project?

I find the sharpen filter to be a very tricky thing. Used in moderation it can sometimes help a bit. Used too much it degrades the image severely. I would use it only where absolutely necessary and then only slightly. You should be able to judge it's effect immediately in the preview window or on an external monitor. It would probably be a good idea for you to connect your TV to your Vegas editing computer so it can be used as an external monitor.

You can also use the convolution fiter set to -.1 on the outside numbers and 20 on the center number. The unsharp mask also helps. All of these filters require a lot of testing to get what you want. But sometimes the focus is so far out that nothing helps.

A good Proc Amp works well if you have access to one.


Three cheers for analog!!!!

Now there's an interesting twist, I was looking at one the other day and my mate who's been in television since the analogue days said 'why would you need one of those, you can do all that in just about any NLE'.
