What MPEG Bitrate?
More is not always better, at least not when the bit-rate surpasses the resolution. Each resolution has an approximate bit-rate maximum, whereas sufficient bits (bandwidth) can be allocated to each pixel. While the MPEG will support bit-rates well into the double-digits, it will likely not use it, and the outcome is simply a bloated file. 352×240/288 = 2.0 MB/s or 2000k max 352×480/576 = 4.0 MB/s or 4000k max 720×480/576 = 8.0 MB/s or 8000k max (same for the 704×480/576 variation) MPEG also has an option of VBR (Variable Bit-rate) or CBR (Constant Bit-rate). The VBR encode only takes the amount of data needed to make the picture look good, and has both maximum and minimum variables to work with. The CBR gives each frame the same amount of bit-rate and forces the picture to use it all, whether it was needed or not, resulting in larger file sizes. On a rare occasion an extra meg (or an extra 1000k) can help out. That is normally limited to situations where the video has extremely fast ac
