There has been a lot of debate on making videos, I figured i could post some quick pointers. After all, ive done a lot of work in this area. Ive pulled some of this off the BSoD Forums:
Good audio is key!! Make sure your audio levels are decent, and they dont flux too much. Bitrate and microphone quality is important. Most headset mics are good enough. The letter P and B are called explosive letters. They have a strong burst of air when you use them, and it causes high bass popping, use a mic filter (the foam crap) to eliminate it. This isnt too hard, just do a few tests before you begin.
Do not try to demux (split) the audio from the video to fix it. Its just easier to fix it in post production. If your audio is out of sync, then poop for you... there is no way I can fix it. There is no magic app that can sync it for you. The main reason it goes out of sync is that the hard drive is working too hard and cant keep up. Increase the compression of your audio and video codecs, but realize this will require more CPU power. Most computers these days will work just fine.
Try not to jump from bright to dark. This is what i call a "transition shock". Human eyes will tune to the brightness levels. If you suddenly jump from dark or bright or vice-versa, it tends to be an annoyance. Try not to jump from console capture to screen capture without a basic fade transition. Even Windows Movie maker can do it, so try and use it so people dont gripe about it.
Use Cam Studio for screencaps. BSoD episode 1 has a good tutorial on using it. You may run your desktop at some insane resoloution, but you only really need 640*480 or 800*600. Camstudio has the ability to capture a specific area, or a range, Play with its settings, its what I use and is very flexable.
Most game consoles can output in a 4:3 ratio, try to keep your screencaptures the same. Typcaly 640*480 is best to use. If you downscale the screencaptures, that is use a resoloution thats higher than the export format, it will throw the pixels off and cause it to blur or become unreadable. Try to keep your screencaptures the same as your export.
Windows Movie maker may be the choice editor. Nothing worng with it, its great for basics. Unfortunately it doesnt have many export profile options. There is a way to make any kind of profile you want, I will add a link to that later.
Not all USB Capture Boxes work with Windows Movie maker. A lot of the PCI cards, even the cheap ones do. But either way, make sure your capture card works with Windows movie maker! if it doesnt, make sure it can export MPEG-2 video, since thats a common file format damn near any video editor can use. The files will be big, but it will be easy to work with. Some USB and PCI capture cards will capture in divx, or other locked/proprotary format that wont work with other editors. Be sure to look out for that, many of my friends and I have been screwed over because the OEM didnt mention the fact that it works with no other software.
Some camcorders (most if not all Sony) can accept a video input, letting you use it as a type of capture box. Check your camcorders user manual for the function.
If you are holding a cam up to a screen, get the exposure correct. Turn off the light to the room, and for the love of GOD use a tripod... If not a tripod a stack of stable books. CRT screens have scanlines which are picked up by the camera, try to use an LCD if you can. There is a lot of nastyness with holding a cam to the screen. It rarely looks good, but if you play with your camera settings, kill ambient lights, have a proper screen (LCD or HD CRT) its possible, but not very desirable.
There is a lot more to be said, but I will say it another day. Here is some linkage:
CamStudio for ScreencapsMediaCoder - For converting media formats to anything, from anything.BSoD Forums on EditngBSoD Episode 1Oh, and for the record, if you do a tutorial, youtube isnt the best hosting. They will downscale the video and make screencaps look like crap. I had the same issues with ******* Sons of Dial-Up (BSoD). Find another service like ViMo, or Google Video. If you want to release it through BSoD im more than happy to make a BSoD style intro for your video and host it on our servers. Just collaborate with me about it.
Hope this helps. Feel free to ask questions, ill try to help.
