Well, I did render it, and it was still choppy (since it was displaying every frame at a slow enough rate for me to perceive it).

I'm using a 3ghz P4 with 1 gig of Ram. The preview window is set to Preview Auto.

you are going to have to get something that will use an algorithim to determine the frames between the frames, to create video that is not there.

Nothing in Vegas does this.

Damn, thanks. Do you know of any plug-ins that do this?

It's odd how an 80 dollar program can sometimes do things that a $600 one can't. I still love Vegas though ;)

I remember when I first tried to do slo-mo with previous versions of Vegas/Vegas Video. There was a setting somewhere that made them silky smooth - for the life of me, I can't remember the name of the setting - I'm thinking it was part of the Render As dialogue, but, went there in V5 and didn't see anything that rang a bell.

I'd be surprised if someone on this board can't offer the solution - and I'd be very surprised if V5 can' t render silky smooth slo-mo's just as well as, if not better than previous versions.

Can someone out there jog my memory? You might also do a search on slow motion. The subject was discussed on this board - that's how I solved my jerky slo-mo problem in the previous versions.

Anyone?

If you apply extreme slo-mo, to the point where you see the individual frames, the results are not going to be that great. You could try adding a touch of motion blur. This should smooth it out a bit, but the effect may or may not be to your liking.

Del -- I think you're talking about Supersampling.

All -- Vegas 6 will render out a slo-mo just as well as Vegas 5, which will do it just as well as 4, which should do it better than 3, and so on. In all, Vegas does better slomo than any other program near its price range. Much better than FCP at their default settings -- but play with Supersampling and things get even better. Also, are you using Velocity Envelopes, or just ctrl+dragging the edge of your clip? That makes a difference. Anything above, say, 25% actual speed looks good -- anything below is very hard to do well. Of course, a lot of any success with slo-mo has to do with your source material -- the higher the resolution of the format used, the greater the original frame-rate, the better the slo-mo.

ReTimer is a plugin for AE and PPro that will do interpolation. If you can't get good slo-mo playing with Vegas's default tools, and you can't/don't want to buy expensive tools to do it, you'll have to look into some of the VDub filters out there.

Do a search on slo-mo in this forum and you'll come up with a TON of threads. This topic has been beaten to death so many times you'd need to bury it twice :D

Actually, jlafferty, it so bothered me that I couldn't recall exactly how I got my slo-mo to smooth out, I've spent the last half hour or so searching this forum, myself. I think the solution in my case was to right click clips where I had added a velocity envolope, then, set in the properties dialog for forced resampling - and that did it for me.

In reading more on the subject this evening, I now understand (or think I understand) that this causes Vegas to interpolate samples from the source material to fill between frames to give the illusioin that the material was recroded at greater than 30 fps. The compromise is that the resamled frames are somewhat blurry when compared with the actual frames - at least that's what glean from the reading I've done this evening.

In my case, the source material was shot in very good light and started out as very crisp material - the trade off in resampling was a small price to pay for what appeared to be a silky smooth slo-motion effect.

I haven't tried supersampling, and will have to read up on it a bit to see exactly how it functions.

It amazes me how quickly I forget just how to do things that I haven't done in Vegas for a while. Slo-mo is something I definitely don't use everyday. Of course, when you have the Vegas forum to rely upon, you get a bit lazy in your note taking, as you can always rely upon someone here to have covered virtually any problem you might encounter with Vegas.

Supersampling should have absolutely no effect whatsoever on slow motion. Resampling will have a major effect.

Read the slow motion section of the Vegas FAQ at the VASST site:

Vegas FAQ

As long as you keep Smart Resample or Force Resample set for the event to which you are applying slow motion, it should look pretty smooth. It may get fuzzy or blurry, but definitely not choppy. Don't mess with the Undersample rate for the event (keep it at 1.000).

I still intend to publish a tutorial on how to achieve silky slow motion using motion estimation software. You can download a product that uses this technology from Dynapel's site (www.dynapel.com). It's called "MotionPerfect." It generates the intermediate frames instead of creating them by simply blending adjacent frames. When everything goes just right (i.e., you have video that the algorithms can handle), the results are amazing. The results can be quite horrid with video that isn't appropriate (panning across a picket fence gives it fits).

Anyway, read the FAQ and you should be able to produce pretty good slow-mo just using Vegas, at least down to 25%.

Duderdude2, a way to improve slo motion, is to may small adjustments to the velocity and render to a new track, mute old track and then made velocity adjustments to the new track and then again re-render to a new track. check rendered event for noise....etc .... and make adjusts as needed. Continue the process till you obtain the visional effect desired.

edit: I take back what I said earlier -- supersampling is just for titles and generated effects. Sorry.
