My Nikon clips are 1280x720 at 23.98 FPS so that's what I changed my project file to use. I exported this at the H.264 setting with default values, and the output appears perfect. However, I need a logo overlay / watermark and trying to do that in the original project, the KDEnlive editor wanted to composite that image with a specific video track; my video is edited and on multiple tracks so I thought it'd be easier to add as a new project (and yes, I'd lose some quality with the re-render). Ok, so the first output looks great. The next run, new project, same project settings and using only the recently exported file and a transparent-background jpg, however, tells me at Render time that there are No Matching Profiles for the H.264 option ? which should be the exact profile that I just used! How can it not match itself? If I use it anyways, I get audio sync issues worse than ever. Attached are the two projects I've been working on (normal edit, and then where I just add the overlay watermark). However, I don't have a short, decent clip to use to demo these sync issues so I'll have to shoot that later and send it in 10 hours or so.
