Time Stretch

[arsa3d]

How can I make a time stretch of a whole composition?
It needs to be 30% slower...

You'll have to render what you have first. Bring your new render into your workspace (or make a new one, it doesn't matter,) twirl open your layer branch in the workspace tree to reveal your footage. Single click on the footage, and the footage controls tab/window should appear. Click the Output button, and on the far right is the time manipulation controls, along with the Frame Blend option. Keep in mind, any time stretch of over approx 20% will leave very visible artifacts, so you may want to compound your frame blends. Do this by only time stretching by 5%, rendering, brinnging this new streched layer back in, stretching it again by 5%, over and over until you reach your desired duration. It wont be perfect, but depending on what the shot is, you could be ok. Try Twixtor (by RealSmart ?) for really nice time streches.

i tried out twixtor and it was cool that you could do time changes via bezier style....but I still noticed alot of blended frames.....does that 5% thing you mentioned apply to this aswell?

I guess the only thing the 5% scheme described above would give you is having no frame blending -- aka duplicate frames. In Twixtor parlance it's "nearest frame" vs "frame blending". When you try twixtor make sure you set Motion Vectors Quality to something else then None.

This is the best time-warping tool I have ever seen or used.

***you can also use this to effectively interpolate missing frames -this means that you could (for instance) render only 20 frames per second (saving rendering times) and then use ReTimer to "make up" the missing 10 frames per second

There may be an easier way to do it now with the timeline editing tools in combustion v3.
