Hi, I am using KDEnlive now for the first time since I upgraded from 12.1 to 12.3 and I have a bit of a problem. When i try to render a project to file, first of all, a video preview window appears - what didn't before. Then the window shows in big and pixely writing "INVALID" in the background, while subtitles and such are shown correctly. The render job window shows "estimated time" pretty much deceasing in real time but stopping at 00:02 left while melt is continuing to be busy in the background. I let it run for 2 hours, then cancelled it. The rendering job was a 4:48 minutes short h.264 clip where I put some titles and then wanted to render it out to h.264. I ran KDEnlive from the console to see if there's any suspicious output but there wasn't. It seems to start the rendering and stuff normally. Does anybody have an idea what's going on there? And why do I get that rendering preview window anyways? -Stefan -- (o_ Stefan Gofferje | SCLT, MCP, CCSA //\ Reg'd Linux User #247167 | VCP #2263 V_/_ Heckler & Koch - the original point and click interface
