Hi,

Is there a way to export still frames, let's say 1 still every second? I've tried various things, but couldn't find a way to achiebe this. Thanks for all hints,
Thomas

See "Rendering and exporting still images and still-image sequences".

Todd,

thank you for your reply! I've had a look at this link, but it only describes exporting a sequence as stills, which is not my particular problem. I have a 3 hour recording from a survey camera and would like to render out just one frame every 30 seconds - can that be achieved with AE as well?

Sure; you'll want to use time re-mapping to speed up your footage.

Okay, before we go any further in this discussion it would be EXTREMELY helpful to know the following:

How will you get three hours of video into AE? That's a bunch!
When this AE project is complete, what will you have made? What do you need to deliver?

Specifics are good. They're vital to the proper work flow recommendation, in fact.

:-) Ok, here are more details about what I want to do:
I got a HD-Stream on harddisk, that was shot continuosly with a fixed camera angle showing the process of building up a large circus tent. The stream was already downsized to SD and upspeeded to make a time-lapse shot. In addition my client wants HD stills of every 10th second of the process for print. That's 900 stills - far too much to export one by one out of FCP, AE or Quicktime. So I thought it might be possible to render out a still sequence via AE - but as I said: only every 10 seconds one frame. Of course I could render out ALL frames and delete the unwanted frames, but that's 270.000 frames to render... :-/

I know of no script that will accomplish what you need to do. But this will:
  • Place the footage in an AE comp, and enable time remapping for the layer.
  • Every 10 seconds, add a time remapping keyframe.
  • When done adding keyframes, highlight all of them and use the Toggle Hold Keyframe command.
  • Move the keyframes to the beginning of the comp, one keyframe every frame. You'll now have a something like 900 consecutive keyframes, almost exactly 30 seconds' worth.
  • Save the project and render an image sequence.

It's several hours of work to set and move all those keyframes, but it will do what you need.

Hello Dave

thank you very much for your reply and your solution! Nevertheless, this procedure requires a lot of time... but it definitely is a way to accomplish the job. In the meantime I've found another workaround - I post it in case anybody else needs a similar solution:

- add the source file to a composition
- change the composition's framerate to 1 frame / second
- add the composition to the render cue
- in the render dialogue set the frame rate option to: Use this frame rate: 0.1

All the best

Thomas
