Excuse me guys, this topic seems to be MJPEG related right? I also have a related question. Recently, I got a video of MJPEG from someone else and it was from a camcord i think. I could not open it with our common players like Windows Media Player and VLC. Then, I find a converter in the article "http://www.videoconverterfactory.com/tips/mjpeg-converter.html". But here come the questions. I want to convert it to MP4 for playback, however, I do not know how I can preset the parameters. There are bit rate, resolution and frame rate. I want to know whether the higher bit rate and resolution I set, the better output quality and a higher definition it will be? What is the difference between bit rate and resolution? I cannot understand it. Another question is should I choose MPEG4 or H264 as the output format, which one is better?
