Any free good video encoder that has join multiple video feature & constant quality feature to encode? Currently I use Vidcoder that has constant quality feature by default set to 20. I like this as I find the encoded quality identical to the original with good file size compared to the original i.e not very big. But join multiple video is not there in Vidcoder. I have few movies that were downloaded as playlists. They are in 15-17 parts. All are 640*480 & audio properties & duration are same except 3-4 movies last part have less duration, all parts have different bitrate. I tried many free multiple video joiner without encode but all gave probs i.e at few places in the video green screen or gibberish video. I know re-encode will work. I tried Freemake Video Converter & worked. But didn't like the encode quality, had selected "same as source". So I am looking for a free good encoder that has video joiner & constant quality feature. Constant Quality is also called Constant Rate Factor/CRF, right? So any free good video encoder that has join multiple video feature & constant quality feature to encode?
