23.1 version doesnt support jpeg?

[Louise23291685t38e]

I recenlty updated to 23.1 version and my jpegs in the timeline are now corrupt or not supported. When I opened my project it said something about legacy title not supported and converting it into a source graphic, are jpegs not supported anymore? How do I fix please?

JPEGs are supported, but the error you're referring to is letting you know that the old Titler system is no longer supported. Did you have old titles that were never converted that contained JPEGs in them or are these two different issues? Screenshots would help here, but can you right-click on the JPEGs in the timeline and reveal them in Windows Explorer or macOS Finder? If so, then they're actually referencing photos, but if not, then you might be looking at legacy titles.
