You didn't tell much about the type of images you're willing to animate. If you want to make an informed choice of a video codec, the general characteristics of your images/animations need to be taken into account. Are they continuous-tone photographs or cartoonish animation (large flat areas of discrete colors) or what? High-motion or low-motion? Do you have storage space concerns? etc.
I'm going to give you some pointers, anyway.
You can buy an M-JPEG codec here: <http://www.morgan-multimedia.com/> or here: <http://www.mainconcept.com/products.shtml>. (There are downloadable demo versions which you can try before you buy.)
If the nature of your animation is cartoonish, you might want to try a lossless codec such as HuffYUV (free, <http://neuron2.net/www.math.berkeley.edu/benrg/huffyuv.html>) or Alparysoft Lossless Video Codec (also free, <http://www.alparysoft.com/products.php?cid=3>).
Since I will be using the animations with DV footage later on,
Then what's the use of creating them in higher resolution first?
would I be better off using a dedicated video editing package to create
the animations in the first place?
Not necessarily. The thing you need to take into account, though, is that normal (standard definition) video is usually interlaced. If you want to make the motion quality of your animations absolutely silk-smooth, the only way to achieve this is making your animations interlaced as well (see <http://www.lurkertech.com/lg/fields/fields.html> for a good explanation.)
Generic animation packages usually cannot produce interlaced animations, but you can overcome this problem by rendering your animations in a progressiva fashion at 50 fps ("PAL") or 59.97 fps ("NTSC"), using the full video resolution. Once you have your animation in this kind of format, you can use video tools like Avisynth <http://www.avisynth.org/> for discarding the odd and even lines from adjacent frames, and weaving the remaining parts together into interlaced video frames.
I think of video editing as being limited in the range of resolutions that it handles, as it is usually focussed on specific TV standard resolutions. Is this the case or can I create custom resolutions?
Some codecs - such as DV - are very much tied into the video world and do not let you to use any non-standard resolutions. Many others will let you choose a resolution to your liking, but if you render your animations into a non-standard format, you can generally only display them on a computer. (Unless, of course, you're willing to convert them to video resolution later, but what's the use of an intermediate higher resolution non-standard file, then?)
I'm finding there's an awful lot to learn as a graphics newbie.
You might want to take a look at <news:rec.video.desktop>. That's the group where these kind of things are usually discussed.
