To start off, I deeply apologize if this problem has been discussed and solved in some other topic, at least I didn't find it. Aaand sorry if this is in the wrong place too.
But anyway, here's my problem. I use Final Cut Express 4.0.1. I haven't been editing for a year now, but now that I got the inspiration and time again, I run into some techical troubles. I took the same footage files I have used in a project before, .mkv files processed with avidemux with this guide
. Buuut, now that I import the files to FCE and try to play it with the editor, it only says "Codec could not be opened". And when I try to render it, it says "Codec not found. You may be using a compression type without the corresponding hardware card.". I figured there might be something wrong with the files since I moved them around from one computer to another with a USB flash drive and stuff, so I got new un-compressed .mkv files (1920x1080 x264 FLAC) and compressed them with Avidemux, with Huffyuv as the... codec (I'm sorry I'm this bad with technical stuff, this is why I'm asking for help) and .avi as the format. But the same problem repeats. So how should I save the files, or what should I download to get them to work? Thanks a lot in advance.
EDIT// okay I tried using MPEG-4 ASP (DivX) instead and after downloading DivX it worked in FCE. However, I get flashes of the DivX watermark, so is there any better options? Or do you know how can I get rid of the watermark?
