Hi annag
This is an interesting problem and I have been looking for a workaround...Here it is......
Your 10 minute clip at 30fps will contain 600 x 30 = 18000 frames You require that this is converted into 1 frame every 5 seconds. That makes an output clip of 120 frames. At 30 fps this represents a clip of 120/30 = 4 seconds duration. (To put it simply your 10 minute clip will need to squashed to 4 seconds which represents your 120 frames every 5 seconds.) :o
Now...
Place your 10 minute clip of 18000 frames on the timeline and change the speed to 5000. This should produce a 12 second clip of 360 frames (at 30 fps) .
Now save the timeline as a sequence and then load it back (Should remain 12 seconds duration)
Change this new clip speed to 300. This produces a timeline clip of 4 seconds. (On paper 120 frames)
To check, step along this clip frame by frame and it should reach the end in 120 frames. You have now got your 120 individual frames (1 every 5 seconds) out of the original clip.
According to C-major exporting this as an image sequence should give a frame-frame -frame images. i.e. VP ought to export 120 frames which is what you want..
However... This doesn't seem to happen..:huh::angry:🙁 you get hundreds of images probably because VP still looks at it as an original sequence and not a completely new clip.
The solution is to export your new 4 second clip (sequence) as an mpg at contant 30fps first
Now load your exported 4 second clip back into VP and re-export it as an image sequence.You should now have 120 images in your destination folder which is what you were after..
