Aspect Ratio
Using my 360 camera, I exported a clip in what the software calls 2.35:1 aspect ratio. (My understanding is that this is 21:9 aspect ratio) This yields a clip that is 5076 X 2160. So when I try to import the clip into Bogart, I choose in the project setting, UHD 4096 X 2160 21:9 aspect. The thumbnail in the storyboard and scene bin of said clip, looks correct. But the preview window has black bars on the side. And indeed if I play the clip I get a squished image with black bars on the side. So I try importing it into another project, this time UHD 4096 X 2160 19:10 aspect. This shows a proper 21:9 image but with black bars on the top and bottom. The image is not squished. In both instances Bogart has to convert during import because of the extra 80 lines of horizontal resolution. If I Google 19:10 aspect ratio I don't see anything. So if 21:9 is 2.35 to 1, what is 19:10? 1.9 to 1? And how can I get my 21:9 image to not be squished? Cinemascope doesn't work because that is only for converting 4:3 and 16:9 aspect ratios. If I export a rendered clip in both projects, the 21:9 clip has black bars on the side and the 19:10 clip has black bars on the top and bottom. Both images are not squished, so they look correct on export and both are at 4096 X 2160. The whole thing has me utterly confused. Not knowing which aspect ratio setting in Bogart I should use. I have a feeling it's the extra 80 horizontal lines that is confusing Bogart. The original footage was shot in what the camera calls 5.7K.

Re: Aspect Ratio
Please send a short scene to forum@macrosystem.at so I can take a look at that strange format (by Wetransfer, Google Drive, DropBox, OneDrive...)

- Normaly for 360°, the black borders should be on top and bottom
- And as soon as the 360° check-mark is set within the Scene/Storyboard Export-menu, the black borders are cropped any not in the resulting file.

Re: Aspect Ratio
Thanks for the original recording. So that's not 360° footage, but just a wide angle lens (or it has not been stitched yet and the second halve would be missing).
As for real 360° footage, a single picture would have to look like MOST OF THOSE and it would be able to grab rotate the video LIKE THIS, once uploaded to YouTube or played by a 360° VR player
So the 5076 x 2160 pixel video is just a too wide video and not 360°, as I thought before.
Since there is no TV with 5076x2160, you could:
2.35 * 9 = 21.15
So 5076x2160 is 21.15:9
Therefore, as close as you could get there with 4k Digital Cinema resolution 4096 and 21:9 Cinemascope aspect: PICTURE
But if you don't want the black borders on TV, stick to 3840x2160 16:9. ![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)

Since there is no TV with 5076x2160, you could:
- scale the video to fit into the UHD1 standard of 3840x2160, getting black borders on top and bottom
- scale the video to fit into the 4k Digital Cinema standard of 4096x2160, getting more black borders on a UHD-TV, but less in Cinema.
- crop the highly distorted border either to UHD1 16:9 or 4k DCI 21:9 - by selecting "adjust aspect = no borders" in the import menu
2.35 * 9 = 21.15
So 5076x2160 is 21.15:9

Re: Aspect Ratio
Thank you for the detailed response. Yes, it is not a 360 video but it was shot with a 360 camera originally. I created the original clip from the 360 video.
