Time lapse with multiple video clips

i6pwr wrote on 4/11/2012, 11:46 AM
With Pro 10, how do I take all the clips and compress them all at once? When I click on the last clip, it will only compress that clip..is there a way to compress the entire footage or do I need to render it first?

What I have is nineteen 15 min clips..I thought it would record for 5 hours without any seperate clips but that's my goof, and I want to compress then use the event velocity.

Do I need to compress each clip individually?

"is there a way to compress the entire footage or do I need to render it first?"

Try this:

With the focus on the timeline, triple click under the events to select all of them. Enable Auto Ripple (Ctrl + L) All tracks, markers and regions. Press the Control Key and drag the edge of each event one at a time to reduce (or increase) the duration.

I seem to remember someone (RS170 perhaps) mentioning a method for doing them all at once, but I couldn't conceive of a search argument in my current state.

It may have been me but I can't remember mentioning it either.
You can't use a velocity envelope as that only works for one event at a time but here's the workaround.
Click the video portion of the first event.
Then shift+click the audio portion of that event.
Go to the end of the timeline and repeat this shift+click process with the audio and video portions of the last event.
Press 'g' to group everything together.
Hold down the Ctrl key at the end of the last event and drag it to the left until you can't drag it any further.
This will give you a 400% speed-up.
If that's not enough, save the project, start a new one and import the veg file you just saved.
Now that it's a single event, you can apply a velocity envelope as well as the Ctrl+drag trick for a further 1200% increase.

edit: forgot to mention that you could just save all the events as a veg file, bring that into a new project and then apply the velocity envelope and/or the Ctrl+drag technique, depending on how fast you want it sped up.

1. You have to first group the events if you want to "Ctrl-right-drag" them all at once.

2. The way I'd do this is to fiddle around with one event, using either the event properties (you can right-click and set the playback speed for the whole event); the ctrl-drag method; or using a velocity envelope. You can also use any combination of these things to get things going even faster. Once you have what you like, copy the event, select all the other events, and then use Edit--> Paste Event Attributes. This will copy all the event properties (including any fX and pan/crop settings), including the velocity envelope and other velocity settings you have set.

I'm still unable to compress the footage, tried the triple-click and I can get everything highlighted but only the last segment will compress.

Right now I have the velocity set at 300% (full) for all the segments, should I render the project then compress the new video? Granted my PC is decent but i'm looking at a crazy-long render time, what is the best format to render under for this if I need to rework the project?

johnmeyer's suggestion to group the events was sound advise. When grouped, all the events should compress or expand at once.

"You can't use a velocity envelope as that only works for one event"

Well, you certainly can use it if you apply it to all the events individually. 15 doesn't sound too onerus to me, especially if doing the same, straight velocity to all of them.

At the risk of repeating myself: you first must group the events (select them all and then press "g"), and then, while they are all still selected, "ctrl-drag" the last event (to the left) to get all of them to speed up by the same amount.

Nested project?

Not a nested project...but I did manage to compress the footage. For the life of me...I did highlight all the clips and pressing G, then I took the last clip and that's the only one that would move. However, I did manage to take the clips individually and CTRL-drag each one to the laft as far as it would go.

Now I have all of them compressed as far as they can go, then I added the velocity envelope and set it at 300%. Is there any way to speed it up further? I can take the playback slider and when it's at 12-16 that's about the effect i'm looking for.

If I cannot then that's fine but so far so good.

Render the lot to a new file, then use this new file for further speed increase. This also eliminates having to work with all 15 clips individually after that point.

Alternatively, drop your sped up project into a new project as a nested .veg file and speed that up.

My edit seems to have gotten lost so I'll repeat it again.

Save all the events as a veg file, bring that into a new project and then apply the velocity envelope and/or the Ctrl+drag technique, depending on how fast you want it sped up.
Repeat if necessary.
Doing it this way means no rendering degradation if you import it again.

To avoid an intermediate render, speed up as much as you can, save the project, and then drop the veg file from that project into a new project in Vegas. Speed that up using the same techniques you used in the first project. You should be able to get to what you want, and you'll avoid the time penalty (and possible quality hit) of doing an intermediate render.
