I'm actually going through this process myself. It really depends on what type of equipment you have. PC or Mac? Do you have a smart phone? Knowing the type of equipment would help walk you through more specifically how to help you, rather than just saying, "put the video clips in the editer and edit to the desired product." Which is essentially what you do.
I've been learning to do some basic editing on my iPhone using iMovie. This system is great in that the iPhone takes great video and has the power to edit, and iMovie was free with the not-so-free phone.
If you let me know what you're working with, I can try to give you a little more information...
I have a camera and a PC. I take pictures and then take the SD card from the camera and plug it in the slot. (not very technical understanding of how this works, but it gets pictures where I can edit and post them).
I set up my tripod and my theory is I focus it on what I want to video, press record, then take the video to the computer and somehow magic happens.
No phone, tablet takes crappy quality photos and videos mostly because I can't hold it steady.
Even a few keywords I can ask google - I don't know enough about this to know the right words to learn from google what I want to ask it.
The easiest thing would be choosing a video editor, then you know what to search for. Lightworks seems to be a great free option. searching Youtube for lightworks tutorial will probably give you hours of how-to's.
I made the video in my Siberian Peashrub thread using lightworks. I was able to cut the videos together and add some titles and notes. I could also have added an audio track with a voice-over or music track. It took about an hour to make this one. It's more tedious at first but it gets a lot easier as you get used to the controls.
I used an old Cannon powershot camera so the video is rough to begin with. I moved the files to my PC, imported them to lightworks and then got busy chopping them up and putting them in order. I suspect if I had a better camera, the end result would look much better. All still, no bad for a free deal.
