Help with Video filters in Sony Vegas 8.0b

[Fahad]

Hey Guys sup everyone. Newbie here. I have Sony Vegas 8.0b installed on my pc. I have worked a bit with to understand the editing and stuff. The point which i want to ask you Gurus out there is like i have a clip of lenght 2.00 minutes. I can add filter on that clip. Lets say i want to add Noise reduction Effect on that clip. When i select the filter and apply the effect it applies itself on all the Clip. What i want is to apply the Video effect only on some specific Time like from 1.00 to 1.25. Also keep in mind i dont want to split the clip as i have a ton of clips loaded in a single project. So if i have to do the filters like this i would have to split each clip in to 30 parts which will be hard job.

Any help or Tips would be appreciated.


Thanks

Fahad

When you apply a filter (Event FX) and the filter window opens, you should see a mini timeline at the bottom of the window. if not, hover the mouse pointer over the bottom edge until it becomes a drag point, and drag the windows down.

With this window you can add keyframes and adjustments that affect what the filter does, and when. Set the filter values to zero at the beginning of the clip, and add a keyframe. Add a new keyframe where you want the filter to start working, then adjust the settings to thwat you need. Add a new keyframe where you want the filter to stop having an effect, and set the values to zero again.

Thanks for a fast reply mate. And Yeah i tried that Keyframes thingy but cannot understand them much better. It would be really cool if some one get in a deep intro to the keyframe thing.

I am trying to understand why you would have to split all of the other clips into 30 parts -- can you describe your timeline a little bit more, and how the fx should apply?

Vegas often has many different ways to accomplish the same thing, so depending on your timeline, we might be able to offer additional options to achieve your goal...

Yeah thats what i am talking about i want to apply a video FX without splitting all the clips. My time line is not much complicated. I have like 4 or 5 Clips of average 2:00 minutes each and a Audio Track of lenght 6.00 minute. What i want is Like where i put the First clip which is of 2 minutes lenght i want to apply a Video FX From 1.10 to 1.25 without splitting the Clip. To do so i would select the Puzzle button at the end of the Clip and add the FX but the problem is the FX get it self applied to whole Clip as i dont know how to use the Keyframes as guns1inger said.

I'm still not sure why you would have to cut the other clips into 30 parts (unless you have to apply the filter to multiple sections of the same clip?).

For me, I usually duplicate the track, and then get rid of anything but the section(s) I want the fx to apply. The fx track should be the one that is on TOP of the original (when looking at your timelines).

Hopefully this will be enough to get you started

Add an Event FX to the clip, and the FX dialogue should open and look like this (this i s the light rays filter - actual parameters will vary)



Notice that you already have a keyframe on the first frame of the clip. Right click on the keyframe, and select Hold.



While you are still on the keyframe, set your values to whatever is appropriate. In this case, I have set the strength to 0, so the filter will have no effect.

Next, move along the timeline to where you want the effect to start having an influence.



Add a new keyframe, right-click and select Hold. This will be the last frame before the effect begins. Move forward one frame and add the next Keyframe



While still on the new keyframe, set your parameters to whatever is needed for the effect to look the way you want.

Now if you preview this, you should see the clip play without the effect until the third keyframe, when the effect suddenly kicks in. If you want the effect to gradually fade in, leave a longer gap between the second and third keyframes.

Stopping the effect is achieved by reversing what you have done so far.

I know this is very brief, but it is getting late here. It should get you started and if you also read the help files a couple of times it should start to make sense.
