Is there a free video editor that support loads of codecs like VLC Media Player does? If there isn't a free one, is there one you can buy outright and not have to pay monthly or licencing fees? I've tried editing only with Windows Movie Makers but that doesn't support any of the codecs of the videos I'm trying to edit. I don't want to do major editing, I just want to add a watermark to the videos and maybe a short clip at the start of them. Thanks.
