Is h264 a codec?

A codec based on the H. 264 standard compresses a digital video file (or stream) so that it only requires half of the storage space (or network bandwidth) of MPEG-2. Through this compression, the codec is able to maintain the same video quality despite using only half of the storage space.

Is h264 lossless?

H. 264 is a lossy codec – it throws away less important bits and only keeps the important bits. PNG is a lossless codec. … Bit for bit, the original source image can be recovered from a PNG encoded image.

Which is better MP4 or AVI?
