Picking a Video Encoding.

Recently I purchased a camcorder to document my child as she grows up. Nice thing about it is that its a digital camcorder, and through a Firewire connection I can upload video to my computer, and create clips that I can send to the grandparents.

Only problem is which video encoding to pick. Through some video editing I've done previously, my first choice was obviously MPEG-2. Its pretty standard, considering its the encoding used in DVDs. Only I forgot that because MPEG-2 is a licensed technology, typically one needs to purchase some DVD player software in order to get a MPEG-2 decoder installed on one's computer. And because of that, a few people I had sent some clips to were unable to view them. Doh!

So I began searching for a different encoding, one that is supported on a variety of platforms - MacOS, Windows and Linux or Solaris - and that one that does a decent job of compression, something suitable for broadband, but not necessarily streaming.

I ended up putting together a survey of several different formats. But haven't chosen one yet. However, in my quest to find out more about different available encodings, I ran across a set of pages at MIT. A Video Guide for the MIT Computer Graphics Group. The Compression and General Video Info sections I found to be pretty good overviews several topics.

Whoops, I just realized, the best pages on the different encodings aren't even linked from the main page. The Codec Comparison goes over 20 or 30 different encodings, probably half of which I never heard of.

DivX? or maybe Quicktime?

Ah, that's the interesting thing, my friend. Quicktime is more of a container than an encoding. Within the container, many different encodings are available. The one that the MIT pages suggest for Quicktime is the Sorenson 3 encoding.

Have a look here... Doom9 did a comparison in December that Slashdot picked up on. http://www.doom9.org/codecs-104-1.htm

I've been through this mill for exactly the same reason (memories of the children growing up!). I started of at www.adamwilt.com for some basics on DV technology. Recently, I've been trying to get more serious about editing (I'm on Windows so I can't vouch for iMovie/FCP) & at a reasonable budget I currently favour Sony's Vegas Movie Studio and DVD Studio package. I hadn't gotten as far as tinkering with various encodings yet - I'll take your lead!

There's a pretty good explanation and comparison here: http://www.gromkov.com/faq/faq2004-0070.html I'm leaving the most important stuff in the DV codec. It's 25MB/sec but since it's the camcorder's native format there is no additional loss and if/when a standard ever settles out you can convert to that.
