Thnx man, I've already applied gaussian blur on it.
but not only grains have disappeared but also the sharpness of the footage.

It's a trade off - if for instance the original footage was not well lit, there's less information there to do anything with, so it's very hard to get it back.

Similarlarly applying Sharpen also has this same trade off - it may make some parts look sharper, but may inrtroduce artifacts elsewhere, and the result can often be an unwanted artificial look.

If you have grains because you started with a smaller sized resolution, you could try supersampling. (Envelope on Master Video track)

Could you maybe say more about the reason you have grains?

It's not for Vegas... but Grain Surgery v2 for film and DV is pretty good if you have Adobe After Effects.

If you have enough time between now and your delivery deadline, you can try "median." There are also some temporal filters, if you want to work outside of VV.

What is "median", tried a web search but get so many hits as its a pretty common word...

"median" is built in to VV. It is one of the Video FX, but it is extremely slow, because it does so much computation.

Thanks!
I thought when he was talking about working outside of VV it was some other product!

Don't forget VirtualDub! Its free. It has wide support and is extremely simple to use and many people have developed some very specialized video filters for it. Satish came out with a plug-in so you can use the filters directly from Vegas. If you want to run it as a free standing application you need to export as uncompressed AVI it won't except the Vegas DV MPEG formats because of the CODEC used.

Without seeing your project can't be sure which VD filter. You could start with either Dynamic Noise 2.1 or 2D cleaner. In fact you may want to use both.

Once you are inside VirtualDub (either stand-alone or in the Satish plug-in adapter), you might also want to take a look at the "Smart Smoother" plug-in. I used it extensively on my last project, and it did a great job of preserving edge detail while greatly reducing noise in flat areas.

Not to be a doom sayer here but I tried a lot of those with VirtualDub on a grainy video that was underlit and it helps from AVI to AVI but when you go to Mpeg2 for DVD it ends up looking almost worse than the original grainy video.

I'm certainly no expert with V Dub or VV4 so maybe I didn't use the correct settings but I spent a lot of time on it and the output from V Dub to a Avi, (I used the Main Concept codec) looked a lot better but then after making a DVD with the output I decided it was almost a trade off of the grain or the filtered video after encoding to Mpeg2. I sure would like to know someone elses experience with this.

Have a good day!!

As Richard said Smart Smoother is another good one. Again how successful you are depends on your source video. Sometimes a combination of filters in VirtualDub then later other FX filters in Vegas works well on one project and isn't too good on another. Also converting from AVI to MPEG may at times undo some, even a lot of the improvement. Also remember both in VirtualDub and in Vegas the ORDER the filters or plug-ins (in Vegas in the plug-in chain) can make a dramatic difference in how effective the filter is.

Makes sense, if you had grainy DV video from low light noise, how would you tackle it and with what settings. I have a completed project(mentioned in my previous post) that I would maybe look at again if I could get some of the noise out. As I stated above, when you preview the results after VB it looks much better but the results after Mpeg2 were a trade off almost.

Always looking to learn. Any help would be appreciated.

Have a good day!!!

thnx guys for all of ur helpful advices, of course all of effects and plugins that can do the task for me takes a long time to render & there's a deadline to be met, and i've too many difficulties the source is 352x288 MPEG2 and the output must be 384x288 MPEG1 SO IT'S A VERY HARD JOB but, thnx for helping.

Doormill:
The "Smart Smoother" in VirtualDub has the effect of reducing differences between nearby pixels as long as those differences are below a certain threshold. The implication is that noise is a sort of granularity that is lower in "intensity" than edges of objects in the scene. For this, SmartSmoother works well, and I used it extensively on my last project as a final step before MPEG2 encoding. The result was that I was able to encode at a pretty low bitrate (~5Mb/sec) yet with reasonable "Q" (quantization) level.

When used to excess, however, SmartSmoother tended to make video look "cartoonish" in the sense that there were broad areas of a single color.

The ideal would be to capture the video without noise in the first place. I have come to conclude that this is the reason that Hollywood is able to create gorgeous DVD images at a very low bitrate--their source images have very little random noise, and noise is what drives an MPEG2 encoder nuts.

Thanks for the reply. It's been a while since I looked at SS in Virtual Dub but what settings have you/would you used on a video with low light noise.


Thanks in advance

Have a good day!!!
