Camera Recording Speed

[Anonymous]

Hi everyone,

How can I reduce the speed of my recording. When I use cameras for recording the speed is very high and while watching it, it is disturbing.

Thanks all

Speed is a function of total frames, and the playback frame rate (frames per second).

If you preview a flythrough with OpenGL, there is NO control over the frames per second as there is when you save the movie (either from OpenGL or render).

With the Path dialog, you can set the number of frames between cameras. With the compression options for saving the movie from the fly-through dialog, you can change the frames per second.

So... if you have frames/second at 25 and 25 frames between cameras, then however far apart the cameras are ... you'll move between them in 1 second.

There are various standard frame rates for incorporating a movie into a video editing timeline - e.g., 24 for film, 25 I think for PAL, 29.96 for NTSC, etc. But, if the target it just for computer viewing (e.g., with QuickTime), none of that matters. A frame rate as low as 15 fps can be adequate, and allow both faster rendering (fewer frames) and smaller files (again, fewer frames).

So... you have to play with both. ArchiCAD's fly-through technology is quite primitive relative to all competitors as you have only the one parameter - frames between cameras on a path ... rather than being able to specify the number of frames between each pair of cameras (= along each path segment).

Thus... if you want a very slow motion between two cameras and then faster between the next two... there is no control in AC. Instead, you have to fake it by placing additional cameras along the first path to force the generation of additional frames. (Or you can generate multiple movie segments with different paths - e.g., from the first to second camera as one movie, from a copy of the second camera to the third as another path, with different frame count - and then combine them all later.)

Hope that helps.

Cheers,
Karl

Dear Karl

Thanks a lot for your advise, what I got from your advise is that I have to increase the number of cameras on my path to ensure lower speed recording.

Or, as Karl said, increase the Inbetween fames in the Path Options dialog box, or a combination of adding cameras and frames.

You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.

I am making my 1st video. Wanted it to be a simple fly around the structure. No fancy in and out, just a view that circles the structure from one simple center point. 1st movie I made it was 2 seconds long and I had 13 cameras placed with 60 frames between cameras.

Now I am waiting on the computer to make a movie with 38 cameras with 80 frames between them. HOPE this comes out right as it will take hours to make. Still not sure how all of this works, I have read all of the threads on this and a lot of the jargon is not known to me, and the help section isn't very helpful. Feel like I should have like 20 computers with 20 different settings and see which one goes the best.

Also making it in the black and white setting as the client complained that they did not like the pink brick and wouldn't let it go even though I said that is not the brick that will be in reality.



Is there a tutorial anywhere?
