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.

I’ve had good luck with Lives. I’ve been able to accomplish things with it that I couldn’t figure out how to do with the others. My main use of video is for web sites. I’ve even created a video sequence from a JPEG still which I then manipulated with Lives tools and output as an animated GIF. I further tune the size of the animation in GIMP which allowed me adjust the the frame rate on a per frame basis.
Last 5 years of my 7 years Linux experience I was regularly challenged by day-to-day video editing tasks. Main content was 720p/1080i/1080p in ts/m2ts/mp4/mov. The most useful instruments that produced a really nice results was combination of avidemux, kdenlive and VirtualDub (under Wine). As per my experience you are able to get excellent results with those tools but the problem is workflow really uncertain and not stable sometimes. Lack of features also has place. But the situation changes. Right now Kdenlive project is really nice. It has tons of features and stable enough for relatively serious editing/finishing. I am sure this won’t be too hard for any person interested to learn Kdenlive workflow. Otherwise this person is too lazy for Linux in general. You may find plenty of video lessons on ytube/vimeo.
I’m having trouble with avisynth, just the process of editing with it. I know virtualdub is connected with it, but I can’t find anyway to connect virtualdub with windows movie maker, well to open it(capture video). Anyhow, I know will try Linux. Will it give the same quality as I see on my computer when it is uploaded to youtube? Yes, beginner here…
Using Linux does not mean that you can’t have high-quality software on your system. Apart from the video mentioned above editors, there are tons of other software available in the market for Linux. Some of them are aimed at professionals (just like Lightworks, DaVinci Resolve, and Blender), while others cater to the requirements of beginners (similar to Shotcut and VidCutter). Moreover, you will also be able to easily download and install video editors on your Linux system, as most of them are already available on the app store.
Like you, I’ve never been able to keep Cinelerra open for more than 10 minutes but in my case, the reason wasn’t the ugly UI. The problem is rather that it is a total crashfest! I do not know a single piece of software under Linux that exhibits that many lockups, race conditions, segfaults etc etc. Heck, on my system, it can’t even load a project that it saved 2 minutes earlier without crashing and that sadly ruins the featurewise winner of the competition completely.
I’m so pleased with this software that I have been paying a monthly membership fee ever since my free trial expired. I use Content Samurai for YouTube affiliate marketing. You can too. Just add a link to your affiliate offers in your video descriptions. I also turn plr articles into videos. That’s right, I don’t have to write anything. I just create videos from plr content.
