H.264 encoding. the differences

[markcurtisp]

I have to encode a video sequence, encode it with various codecs and do a short write up about what changes the codec has made to the video, advantages and disadvantages, my sequence consists of mostly ducks walking around, leaves in a forest, waterfalls and traffic.

I can't see any difference between the original file and the h.264 encode, what should i be looking out for?

apologies if this is the wrong section of the forum

What is your original footage shot in? What codec? What bitrate?

 

[markcurtisp]

AVCHD or M2ts, i'm assuming M2ts is the codec.

15,589 kbps bit rate

the file size and date rate in the h.264 is about half the original file and the h.264 file has 50 fps instead of 25fps.

AVC and H.264 are both MPEG4 codecs AVC. H.264, and M2ts are just file format wrappers for the codec. Differences you could expect to see as you reduce bit rates is macro blocking and reduction of deep shadow detail and loss of detail (mush) with fast motion.
