Hey, today I’m going to talk about DV. I’m not going to get too technical but I think its useful to know what the different formats are when you select the different settings in After Effects or Premier Pro what ever you’re using there are a whole host of different settings to choose from and I intend to give a bit of a guide to what they all mean! I have already covered H.264 which you can find here. Now lets get started!

H.264 is a compression method, this means when you export a video using the H.264 compression it wont come out as “Yourmovie.H.264″ it isn’t a file type. It’s like, the way you make the bread for your sandwich. The sandwich can be cheese or peanut butter, .Mov or .MPEG. But the sandwich is made with H.264 bread to give it that high quality crisp feel and low bit rates for faster downloads and smaller files sizes…

…Still with me? I’m hungry now >_>

“MPEG (pronounced M-peg), which stands for Moving Picture Experts Group, is the name of a family of standards used for coding audio-visual information (e.g., movies, video, music) in a digital compressed format.

The major advantage of MPEG compared to other video and audio coding formats is that MPEG files are much smaller for the same quality. This is because MPEG uses very sophisticated compression techniques.”

Linear editing is the process of selecting, arranging and modifying content (usually audio/video) into the desired sequence.

linear editing is seen to oppose non-linear editing because of the destructive nature, for example in film where the film would literally be cut and paste into position, once it was set there was no going back.

Non-linear editing is a modern day editing method used in film, video and audio production. It is similar to a cut and paste technique used since the beginning of film but unlike with the physical cutting and pasting of film of old the process is no longer destructive.

It is seen to be apposed to linear editing because you have equal access to any frame of the audio/video at any time so the process can go back on its self (non-linear).
