What I was objecting is I go intermediate to avoid artifacts, which can't be true and it looked like you were saying that, originally. Of course, if you have ALL your videos in the same codec, fps rate, resolution, etc, then there is no problem using whatever video editor you choose, to cut and concatenate vids at will. The problem arises when you have different videos, from different sources using different codecs and framerates, and want to created a single remixed video out of ´em. That´s when, in my experience, it works best to convert all source material to very high quality MPEG2 (in my case, and for my needs, if it´s not HD material, DVD-quality framerate MPEG2 works best- I use the ´DVD´ presets for FFMPEG that come with WinFF), do the editing, and get the final result in MPEG2. Then, as needed, one can re-encode from that final video into lower-size files, with more efficient formats and bitrates according to the target destination (e-mail attachment, web site embedding, etc). Of course, raw uncompressed video works best, but I usually don´t have the HD space on my Atom netbook to justify that. I use the above approach when remixing vids from Youtube, and other web sources which often come in mp4, flv or avi. I got sick of different video editors chocking on input vids codecs or whatever, or producing unpredictable results. It seems to me that the MPEG2 codec is simple and understood enough as to not cause any problems with even the oldest of video editors. Editing flv, avi (xvid/divx), and h.264, is more troublesome.

Fernando, any time you edit MEPEG2, 3, 4, etc the image will degrade.
With any of the formats you can get frame accurate editing. The farther
into a GOP, group of pictures, you get the worse the image
reconstruction. Since you must recreate a reference frame, the first
frame of a GOP, you're starting with a worse image. So at least the
initial frames are likely to be somewhat iffy.
With motion JPEG, MJPEG, editing is simpler. Each frame is a full
picture encoded. So all you do is grab the start frame and all the
other frames through the output without ever decompressing anything.
Also a few years ago a SMPTE group did some experiments with MJPEG
vs MPEG for QHD. The conclusion is that for a given bit rate the
MJPEG was at least as good as the MPEG versions they tested. (This
may have changed in recent years.)
You also want to work with at least 422 as your base editing copy.
Things like 420 have stripped out too much information that cannot
be restored except by guesswork.
{^_^} I spent several years coding this stuff as part of a
newsroom application.

Re: Can anyone recommend a good video editing tool?
You can also try pitivi from fedora repositories - it doesn't have many of the features openshot and kdenlive have, but it is good enough for simple editing. Also, if you choose avidemux, don't use gtk frontend - in my experience, it is buggy as hell, while qt frontend is much more stable.

I agree with the theory, and if I worked on broadcast I´d pay attention to that. However, since my point is creating videos for the Internet and sending by e-mail, MPEG2 works fine for me. The point you seem to be missing is that when dealing with different source material, often with LESS resolution than the 720x480 I use as intermediate, when FFMPEG does the conversion it needs to increase the size of the vids, and for this it does interpolation, which actually smoothes the image and reduces artifacts. The last time I tried to use a mix of the other formats as source material, apps either crashed randomly or exhibited odd results when trying to select a given frame as cut point (as if the source material had a full frame every 2-3 seconds, and I wanted to cut at a given fraction of a second, well, KDEnline wouldn´t let me. While when doing cuts on WinFF produced MPEG2 files with DVD-quality presets, I never have such problem. But the last time I did that experiment was in 2009, surely KDEnlive support for other codecs has improved since then. At one point it seemed that KDEnlive´s best consistent feature was the crashing when importing clips. ;-P http://goo.gl/sgJgX Which takes me back to my initial premise: that there must be something that makes MPEG2 easy to support from the get go for programmers, while dealing with other codecs takes video editing apps several iterations to get right untill all bugs are ironed out. And yes, you´re right, MJPEG is the best, but again, I personally find the tradeoff of disk space to be too big. On a desktop with a HD several terabytes big, of course disk space is not a concern. Again, this is not a definitive guide of how to work with video files from a codec expert´s point of view just a statement from an end user about a hassle-free method I found by trial and error, and which I use regularly with great results.
