-what to look for in first cams
Looks for screenshots , sample and the most important COMMENTS !
I would say better go for DVDSCR than CAM as they have better quality than any other PRE-RELEASE like PreDVD , pDVD , CAM etc.
-whats the difference between xvid divx and the h264 x264 category
These are the VIDEO CODECS used for compression of movie
Divx is a commercial product whereas Xvid is an open source program.
Both programs use the same video encoding scheme. So the picture quality is both the same, as Xvid comes from DivX itself
H264 is aka x264 ... Its the most used video codec nowadays .... It supports most devices whereas x265 is still being developed ... It doesn't support much devices , so its almost useless to use x265 !
