The reason that h264 only came to the fore over the last few years is because it is highly CPU intensive.Īs for encoding, I use MeGui and would advise all others to do the same. This is the codec that is used in HD-DVD, and more recently replaced MPEG2 on Blu-Ray - this is alongside the VC1 codec, which is somewhere in between h263 and h264 in terms of ability, but is a microsoft designed unassociated format. I will not go into detail, but h264 is considerably better than all the other standards in use at the moment per unit bitrate (to a point, at which each codec will become lossless). Xvid and Divx use h263, and the newer codecs (e.g. MPEG4 consists of several parts, the most commonly used being MPEG4 part 2 (or h263) and more recently the superior MPEG4 part 10 (or h264). MPEG2 is very good at very high-bitrates for any footage (like 35mbps+), but is useful because it is not CPU intensive, and is a relatively closed (few variations) standard.
MPEG, MPEG2 and MPEG4 are all just "standards". (Gotta know how when you are building a hard disk library of your HD-DVDs and Blu-Rays but don't own a multi-terabyte disk setup).Īnyway, firstly. Despite the fact that most of this thread makes no sense and makes me feel a little embarrassed by the lack of general video-technology knowledge around here, I have decided to chip in, since I am an encoding junkie and spend more time on it than anything else at my PC.
