jQuery Video Aspect Ratio Tools
I had a request to make my jQuery HD Aspect Ratio Tool into a 4:3 ratio tool, so I decided to offer both now. If you need help determining what the width and height should be for your video, HD, or not, feel free to use these helpful tools:
16:9 HD Video Aspect Ratio Calculator
4:3 Standard Defintion Video Aspect Ratio Calculator
The 4:3 calculator could also be helpful in determining the aspect ratio for most images from digital cameras.
Feel free to share these links, I'd just appreciate the credit for building them.
