Black Magic + Canon 8-15mm stitching errors

Hi
I do have some strange issues with AVP and APG when I am stitching black magic footage. I have shot in 4k raw and had a canon 8-15mm lens on with 8mm wide open.

We did a test shot in two different locations and it worked flawlessly. Now that we have done the actual shot, we get massive stitching issues.

The footage was captured on a nodal ninja, and we had 7 shots round and 1 up for the zenit.

As there is no template for BM, I could only stitch as 'mixed lenses'. APG gives me different roll values (which is odd as it was shot on a nodal ninja) and different FOV and computed vocal length.

It would be great to know how to fix this.
I can provide sample pictures privately.

Kind regards
Michael

Hello,

You can get stitching issue if you have a lack of details in the scene? Is it the case? Or If you cannot synchronize the footages properly.
Can you give us more details? Which version of AVP?

Best regards,
Olivier

Hi Oliver
The background is 100% static so there is no sync issue, and the camera is fixed on a nodal ninja mount.
There is no lack of details, but it throws off the FOV etc as there is no stitching template for Black Magic cameras. If you pls could provide me with an email in a private message, I can send the jpg's over to you. I am using the latest AVP and APG versions

Thanks,
Michael
