I make short films, the last one was 30 minutes long, and I used Premiere Pro for it. Premiere was very buggy for me, I don’t know if this is the case for everyone, probably not. I tried (well, let’s say I’ve installed them and looked at them) a few video editors, including Cinelerra, Kdenlive. I found Cinelerra’s interface really ugly (controls, icons…) while Kdenlive seems very clean and functional. I didn’t tried them with real projects, but I’ll try to. But I just can’t imagine Cinelerra is a good software, seeing his ugliness :)
The developers have also added some high-quality video and audio filters and effects aimed at professionals. Unfortunately, this software is not entirely free as it comes in two versions: Lightworks Free and Lightworks Pro. The difference between them is that the latter supports different video formats, while the former does not. Lightworks is available for Windows and Mac OSX as well.
Vidnami is an online video creator software (application) that helps you create fast, easy and professional-looking videos within minutes. It allows you to insert articles into the software and it automatically creates a good-looking video using the text from the article you inserted. It can also add great images, video backgrounds and even text to speech voices.
