"How about your wedding?" "Petty well, "I was really touched and nothing could be more impressive, so I intend to make a DVD for memorizing every moment of my wedding…", "no problem, it is easy". "But the wedding is so long that contains five sections, how can I join them together and burn to one DVD to play on my home DVD player so I can watch them whenever I like". "So, maybe you can figure out with some free tools…"

I am a YouTube fan; I really enjoy making short feature as an amateur and share them on YouTube. But I am not a master as a photographer so there are some redundant segments I would like to cut. How can I do? Is there any free software can accomplish that?

Headaches? Maybe "yes" before, but you can easily smooth away them after you reading the following stuff.

Let me introduce some good free software here:

AVIedit: It is a great tool to work with .AVI files. It allows you to join and split avi files, extract frames. You can change frame rate, duration, frame size, color depth of your videos and other properties, even without recompression, and convert avi clips to bmp and bmp to avi, animated GIFs etc. and there are some shortcoming, the running speed is too slow even a short video unless you have much free time to wait. The supported format is only .AVI, it does not support MPEG-4 video and others such as virtual dub neither Sonic Foundry Vegas, etc. But it is free anymore.

Virtual Edit:
Virtual Edit is a semi-professional software video editing package aimed at ambitious content creators to video novices, who want to produce material with a slick and professional look, on a limited budget.
There is a special video capture utility for users with DV and Digital-8 cameras. If you have a different camera, (for example an analogue Hi8), you must use a third party application or the software provided with your equipment to capture data on to your PC. Then use the 'import' utility in Virtual Edit to add data to your project. Sound good, but also with the free tools the speed is slow and the edit steps are complicated in a way before you read the long help documents and it will not be able to render advanced transitions unless you purchase the full version.

If you are Mac user:
iMovie that comes with every new Mac (OS X),now called iMoveHD and it's a part of iLife package. Apple iMovie '05 is an excellent (and free) video editor for the Mac platform, with advanced video editing features and a lot of addon and plug-in support. You can find more information about iMovie at Apple's iLife '05 site. Note that this software is free only if you buy a new Mac. You can purchase it, however, if you just want the software.

ImTOO Video Editor:
ImTOO Video Editor has three part: "Join", "Split" and "Cut" which means you can join multiple video files to a new one, split one file into several segments, cut one or more segments from the original video and merge them to a new file. It aimed at users intending good quality and high speed with some budget.
