About strobing:
I have a lot of Vegas plug-ins, and not a one of them will automatically generate a strobe effect, but there are several ways to handle it. Unfortunately I'm not at my computer right now, but I'll try to explain
one way as best as possible, off the top of my head, because I want to feel useful.
<ol><li>Zoom in on the area where you want the strobe effect.</li>
<li>On the left side of the Vegas window, where all the video and audio tracks are listed, find the video track where you want the effect to take place, and click the automation button - it should look like a little red cog/gear. Select "Show Automation Controls" (again, this is from memory, so it probably doesn't say that exactly, but there's only like 5 options, so it should be close enough).</li>
<li>Now you have an extra slider on your track options, which I believe is labled "Fade." You can use this or the Opacity slider to get the effect you want. For giggles, let's move on with the Fade slider.</li>
<li>Move the slider to some other position. I think moving it to the left will fade the clip to white, while moving it to the right will fade to black. When you let go, it will also add an envelope (a.k.a. "that line with all the little boxes on it") to the track itself. You'll wanna add points to the envelope and adjust them accordingly to get the desired effect, but make sure that the first point (all the way at the beginning of the video) is set to "No Color," by right-clicking it and choosing (surprise, surprise) "Set to No Color."</li>
<li>If you don't know how to add points to an envelope, right click on the envelope and choose "Add Point." You probably don't want to have them any closer than maybe 3 or 4 frames together, and 3 is really pushing it. The best way to do this (only in Vegas 7, AFAIK) is to first click on the clip where you want the effect to start - if you miss, you can use the arrow keys to get there. Add a point, and then drag it to the line - it should snap into place (assuming you have snapping enabled). Then right-click the point and choose "Set to No Color." This keeps the color level at its normal spot, in the middle. Right-Click it again, and choose "Fast Fade." IMO, this makes for the best strobing effect. but you can try other fade types.</li>
<li>Now use the arrow keys to move the position line ahead a few frames. Add another point, snap it in position, and set it to No Color. Add another point
before that point, drag it to the bottom (for fade to black) and right up against the No Color point which you just added. Congratulations. You have one (1) whole strobe. You most likely want it to keep going for a while, so add more points in the same fashion until you've filled up the space.</li>
<li>You'll probably end up strobing past the end of the space that you want the effect to cover, so when you get to that point, place the position bar at the spot where you want the effect to end, zoom in as closely as possible, and add a point there. it'll probably end up a tiny bit higher than than it was before adding it, but not so much that it'll really make a difference. Now you have 2 extra points after that one, so delete one, drag the other point back, and set it to "No Color."</li></ol>
It's a bit tedious, but strobes are best in short bursts (unless you're just really trying to cause epileptic seizures), so it shouldn't take all that long.
Like I said, there's about a metric buttload of other ways to do it, this is just one. Also, the final result might be easier on the eyes than some other ways.
