I was reading the new manual and I realized I didn't understand the camera and the projector. I thought that the box of the camera remained fixed to the dimensions of the window of the composer and moved the image below (pan e zoom). Now it behaves exactly like the projector, with the image that remains tied to the box and moves and zooms in on it. See the video: https://streamable.com/6rm97 It's been a long time since I've used camera automation, so I can't tell when behavior has changed. Can anyone explain to me how the camera and projector work?
The projector area is displayed with a red frame. The camera area is displayed in green. I have attached a video which shows that I can pull the green frame out of the Comsitor view as long as the projector screen is the same size as the compositor screen. https://streamable.com/1h6sq However, as soon as I reduce the size of the projector frame, I can no longer drag the green frame outside the compositor window. It is truncated inside the compositor window because the project frame limits this image. The projector frame shows you the entire area you can use within this track. The camera frame shows the area inside the projector frame. If the projector frame gets smaller, only this area can be used, everything outside this frame will be cut off.

Thanks Sam; with your words I'm starting to understand. I understand to how it works in your video (as well as in mine), but I remember that long ago it didn't work that way to me. https://www.youtube.com/watch?v=gcEiWQHTpmU&list=PLr12wAaNzDdVSzd8_2pLzio_D0... In the tutorial (from 10'27" to 11'20") the projector remains untouched to FullHD (the output of the project). Moving the camera, the green box remains fixed to the edges of the Compositor view while I pan and zoom the frame. The video is about a year old. Now the green box is not fixed but moves in a way consistent with the pan and zoom I do. That's the right behavior, but why wasn't it like that before? There is something wrong with the way I think.
Andrea: it was changed around September 2018. Below the dotted line is the original email. I thought I had corrected the wording in the manual but apparently I only fixed one place. And if while making a new video, you get some good explanatory screenshots that I can use for the manual, that would be great! (Else, I might have to steal them from your video). I have not spent any time understanding the camera and projector so in the manual just mostly did a "cut and paste" from the cv manual without the accompanying screenshots which were outdated. -------------------------------------------------------------------------------------------- EMAIL RESPONSE: Phyllis Smith <[email protected]> To:[email protected] Sep 9, 2018 at 11:49 AM I don't like it either. GG is going to make a mod and change it UNLESS users are so enamoured with the current way it works and say "please do not change it". And is it later becomes a problem, can reverse it.

"When we drag over the viewport in the compositor window (although initially counter-intuitive), the viewport does not moves but the area of video that sits under the camera's location does, like when watching the output of a moving camera.
For example, when you drag the camera down, the viewport in effect is moving downwards on the video, showing its path towards the bottom of the video, but from our perspective on the compositor screen, we see the video moving up. When you drag the camera right, the video seems to move left, and so on." https://cinelerra-cv.org/docs/cinelerra_cv_manual_en.html#SEC129
I say it freely, I don't like it. I work a lot with the camera and feel that this is an unnecessary hurdle. Do I stand alone with it, has anyone ever thought about cutting off the old plait? -------------------------------------------------------------------------------
The way it is at the moment, I personally think it's better. I see the framework that I also want to move. I pull the frame in the direction I want it to go and the frame moves in that direction. The current operating manner is much more intuitive than the old one. The old way of working has always confused me. However, it still doesn't work properly and in my opinion it's a bug. As soon as I reduce the red frame, the green frame would have to be reduced proportionally. I shrink the whole view area (red frame) of the visible area, so the area of the camera view should shrink as well. I can't have a larger view area of the camera than the area of the projector. If I would now switch from projector view to camera view, then it would have to have the same size, 50% smaller projector area = 50% smaller camera area. Then the view of the red and green frame would be correct. The green frame can be enlarged in the second step, but only after the size has been adjusted proportionally to the red frame. The green frame may also be larger than the red frame, but this would mean a zoom inside the red frame. Sam On 04.04.19 19:04, Phyllis Smith wrote:

@Phyllis. I remember that post but I thought it was just about the mouse/frame direction of movement. I'm reading the Camera and Projector manual, but I'm too incompetent for a good review. Have you seen this video? It's very well done. https://www.youtube.com/watch?v=YzJ0b9XQR3s&list=PLCI9oI4dS9zxOX_gxl7JlyiIFp... but the whole series is interesting, finally some video tutorials in English (thanks to Sam for the report). @Sam. You are right, that's better. You're right about the bug, too. Maybe it's better to open an issue on MantiBT.
I opened a ticket on MantisBT. Sam On 04.04.19 19:48, Andrea paz wrote:
