"You got my clickbait? I got your attention." Always an entertaining email from Stefan! "Nothing on the internet mentions that Cinelerra is capable of editing 360 video's, but it certainly is: with the help of ffmpeg's F_v360 plugin. Either creating the 360 content, or extracting it in a regular video." It may be that no one has experimented with it yet. There is 1 line in the manual about that F_v360 does - Convert 360 videos between various formats - but there are so many ffmpeg plugins it can be hard to keep up. There is also the native SphereCam video plugin that Adam added to HV a few years back and was ported into GG which I think he made a online video of using. :So as you all already expected from my I was doing stuff with Cinelerra-gg that likely nobody did before and noticed some particularities really did not understand. My steps: 1. My project settings remain 1920x1080. 2. Just grab any equirectangular video bigger than your project size. The one I got my hands on was 4096x2048. In my project I want to use a part of this video as illustration of the user experience. This would mean I need to project the equirectangular projection into a flat projection. 3. For the plugin settings that would be input=0 and output=4. What I noticed when I modulated the yaw was that I would never see the entire view, then when rotating the back of the video would 'clip' at -180 degrees. 4. When changing the camera to Z = 0.469 (1920/4096) I was able to get a 360 degree rotatable camera. 5. Setting up d_fov = 120, the image would be closely mimicking the experience. "Now what Cinelerra bring you from this point. Keyframing a property of the plugin, and there it becomes interesting. Plugin keyframes seem to give the control what we are looking for here. I can set the yaw using "Generate keyframes while tweeking", but what I would be actually looking for is the same set of curves that would be available when changing x,y,z,opacity etc. How would I get interpolation working? Could anyone elaborate how Cinelerra knows it can interpolate some of the parameters, but not others?" Maybe IgorBeghetto knows the answer to the above 2 questions from Stefan. Meanwhile I will try to test F_v360 and see if I can make any sense of it. (I need a 360 GoPro camera - ha, ha). "And personally I think what is more fundamentally lacking in Cinelerra: a timeline view analogue to Blender where any property can be placed in view: where I would suggest to normalise the min and max to sensible properties opposed to the current: stack everything on the track and break your project by an unintended mouse click." Sounds like a good idea but I always wonder how hard it is to smoosh in these types of new ideas without breakage.
