Frage von mureis:
Hello,
I have only recently started with digital Videobarbeitung me to After Effects 6.5 pro and Final Cut Pro 3 is available. I would like to create a clip in which two different speeds of the same image run. The final product will be a person go through the picture in real time. The clouds, however s.Himmel pass incredibly quickly.
I imagine so that I basically only two different videos must absorb only as long as the guy goes and the time-lapse recording separately from the sky. In these two shots, the camera then yes s.gleichen place is. Where is everything to me clearly.
But how these two now as described above may join is absolutely unclear to me. Is there something like Photoshop, a la Mark? So that just in the clip with the person s.der dividing line between heaven and earth along a marker, then the sky clears and the two videos overlaid, so that the Zeiterafferaufnahme then back at the level of real-time recording and is only the visible sky is?
Hmm, sounds complicated and somewhat confused, I hope you understand what I mean. thanks for any help
Antwort von JMitch:
What you want to use a mask. Search by clicking on the clip in the timeline-> mask add. The mask is then at first only from a rectangle that contains the entire picture, you can take the form but with different tools can change (points move / add /...). Everything that is outside of your mask is transparent, and the underlying layer is visible.
Antwort von Beckerspat:
is correct, however you want so that the person moves through the building. This would then mean that you have this mask for each frame (one frame) to create them. Is quite time consuming.

If the other video, only the sky can be seen to be, a garbage mask (mask = very rough) but just fine. (If the person is not in the sky rises.
Antwort von Debonnaire:
There are three possible scenarios of your problem:
1. The original sky is virtually free recording (ideally a rich blue) and blue is the same anywhere else in the picture before. In this case, a chroma-key the blue keyen away and the problem is solved.
2. The sky is unfavorable structured, but rises to the person (or other complex shaped image content) is not in the sky and the horizon is relatively straight and simple shape and the camera does not move. In this case, with a (as always synonymous drawn mask) of the heavens will gekeyed away. Problem solved.
3. After Murphy and probability are you but before this case: The sky is unfavorable structured. The colors of the sky come synonymous elsewhere in the picture before. The person and tons of billowing in the wind, trees soar into the sky inside. In addition, you have the camera with the game still going hinterhergeschwenkt. True? - In this case you have frame by frame to create a mask / animate (like always synonymous), so you have the original sky wegkriegst.
Because of the 3rd Case in practice (for inexperienced filmers) is synonymous to the normal case, there is in professional film just the special effects supervisor (see credits) s.Set, the director says during the filming that scene, but his stage so please be that 1 or maybe even the 2nd Happens! :-)
