Animate keyframe insertions?

vitalforce2 wrote on 8/31/2005, 9:58 AM
I have a DV feature divided into eight project files. I'm trying to put the projects end to end in V5 but the master color correction was different in each project ("master" meaning a filter package, set in the Preview Window). I had the project in V6 where nested projects is the ideal answer but I can't get the 90-minute timeline to render without hanging. Ever.

I'm doing this because I'm backing up from using V6 (no freezes in V5). So I have cut & pasted the entire contents of each unrendered project--multi-track video & audio events--into one 90-minute timeline in V5.

I know I could just render each project to an avi file. But because Spot's general advice is to render an intended DVD (for festival submission) to MPEG-2 straight from the timeline, I hoped to avoid the extra render to an avi file. I can't have V6 freezing the way it does on an MPEG render since I can't patch two MPEGs together--so I can't use nested projects, i.e. in V5. Trying to join two MPEGs together, they would play as two separate files on a DVD, causing a very noticeable frame-freeze at the chapter point. Bang, "sorry, we can't use this in our festival," etc.

I thought I'd be able to set keyframes at each "junction" (formerly where each project started and ended, but now of course it's all in one long project) and thought I might use the keyframe timeline inside the FX chain window, locked to the 90-minute timeline, to switch to each saved preset of the FX chain as the cursor moves from one project's events into the next set.

Theoretically I thought this should work, but on inserting a new 'master' preset, it simply replaces the existing preset and the keyframes disappear. So it seems I can't take what would be the wonderful step of locking hard keyframes at the "junctions" and just insert a saved plugin chain. Instead, I think I'm going to have to set the internal settings in EACH plugin in each project's chain, e.g. naming each preset 'project 1,' 'project 2', etc., and keep a paper record of where each plugin kicks in. ..

UNLESS there is possibly a script out there which would automate the process of changing a preset filter package to another one in the FX window timeline?

Anyone with more expertise than me at scripting (I have none at this point) have any suggestions on what to try?

If no suggestions right now, tonight I'm going to try lining up the FX presets so that each chain has the same number of plugins, in exactly the same position when the FX window is opened, so as to make the FX timeline (bottom of FX window) uniform for each filter package. If that happens to work I'll advise.

In your case, it sounds like this is not worth the effort. There will be NO CHANGE in the quality of the DV footage if you render to AVI and then drop the AVI files in another project and render to MPEG2. What Spot was suggesting only affects generated media like titles which is 4:4:4 in Vegas and still images. I assume 99% of your film is DV footage so you should not see any quality loss by just rendering each project to DV and then reassembling them into a master project to output to MPEG2.

As far as a script goes, it is probably much quicker to do this manually than to develop a script for it because you would still have to tell the script which presets to use and where to place the keyframes. That’s most of the manual work right there.

Thanks JohnnyRoy, appreciate the time you took to read my overly wordy post and help me think this through. Absolutely right, 99% of the project is DV with video filters, generated media only occurs in opening & closing titles (end titles are white on black) and a six-second overlay of a moving searchlight effect over an unmoving long shot of what we used as the Birkenau "hospital."

I tried setting and locking hard keyframes at the project points and the Curves plugin just had a mind of its own, doubling its curve after the first frame, etc. I'm used to using Bezier curves by now but don't know the math of them.

Good to hear that I'm not taking a noticeable quality hit on just rendering the projects to avis as before, then putting them on one timeline for MPEG recoding (this had allowed me to set all the audio tracks below the one row of avis, i.e. dialogue track, FX track, music track) so I'll go back to that. Guess as usual, a little knowledge is a dangerous thing. (1. Car needs gas; 2. a match will help me see into the tank better.)

The Celluloid plugin for pushed 16mm, set back a little, worked wonders on this 'film' and I'll post some before/after screen grabs at full res. as soon as I have this monkey wrestled to the ground.

Excellent. I’d love to see them. Good luck,
