How can I put 4 videos together as one?

you CAN use windows movie maker, just drag and drop the parts in the slots at the bottom, and save the whole thing, it will be saved as an WMV file though.

i once put together five parts to make an hour and half movie so you can do it, there is no limit.

if it doesn't work try converting the parts to another format, i recommend using total video converter.

hope i helped..

Easy way, just use a right software. I am using RZ Video Converter which can put multiple videos into one, such as put 4 10 minutes wmv videos into one. Easy to run rz video converter, drag your videos into it, select them, then press "MERGE" button, then press "START" button, then you can get one wmv video. It also can convert any videos or audios between different formats with good quality, if you need in the future, you can use it. Try it by yourself. Yahoo or google search and download rz video converter. Hope it can help you.
