After briefly testing all the various open-source video editors I could find easily available for fedora 13, I came to the conclusion that kdenlive was the best fit. By and large most of the editors were plain unusable for more than 5 minutes or just had too many limitations. kdenlive has its own faults, including that its documentation is not always clear and one must refer to it constantly when figuring out the UI (hint: video tutorials were so useful to understanding the docs). Essentially, I can now do almost anything I need to with kdenlive now, but I would greatly appreciate it if the devs could improve rendering time, update the dvd creation wizard to support blu-ray, and add more rendering options (for example, ogv output does not support quality levels, only bitrates). As for stability, I saw several crashes when I was first exploring features, but none since.

Cinelarra is for video producers who need more than OpenShot, and who want a native Linux professional-quality video editor that supports high-resolution audio and video, and advanced features such as hue and saturation, overlays, denoising, compression, normalization, time stretching, realtime effects, nested sequences, color balance, image flipping, text-to-movie, batch render and batch capture, compositing, and much more. Cinelarra has nice integration between audio and video, and makes it easy to control synchronization. Blender and Cinelarra work well together; create your splendid animations in Blender and then integrate them into a movie in Cinelarra.
Cinelerra is the most advanced non-linear video editor and compositor for Linux. Cinelerra also includes a video compositing engine, allowing the user to perform common compositing operations such as keying and mattes. Cinelerra includes support for very high-fidelity audio and video: it processes audio using 64 bits of precision, and can work in both RGBA and YUVA color spaces, using floating-point and 16-bit integer representations, respectively. It is resolution and frame rate-independent, meaning that it can support video of any speed and size.

Content Samurai promises that you can “Create Stunning Videos Fast” with their app. You can use Content Samurai video creation software to turn articles, blog posts and shorter pieces of content into videos in minutes, or so the creators claim. I’ve spent a lot of money having freelancers create videos for me, so I figured I would give Content Samurai a shot.
