rendering time
Hi. Im new to creative cow. I’ve only recently started video editing and have used Sony Vegas for a while. I now also use After Effects, but AE seems to take a much longer time to render a clip (2hrs for a 1.5 minute clip) than vegas (8 minutes for a 6 minute clip). Im making a mock-up of the Star Wars Intro for a birthday video in AE, and so i just use some text, and animate it moving into the page by keyframing position and anchor points. The file size after rendering in AE is 2.5GB. Is there any way reduce this and reduce rendering time? The movie is rendered as avi. I generally use digital still camera video’s in vegas(from a CANON IXUS50). Why is vegas much quicker and why is the file size smaller for longer clips?
Thanks

File sizes are a function of the CODEC 9COmpressor/Decompressor) that you use. AVI is just a container (video architecture). A video architecture requires a CODEC to work with. There seems to be lots that you don’t know and unfortunately this forum isn’t meant for newbies.
Please check out the COW’s AE Basics Forum and perform a Google search on CODECs to get a better idea of what’s happening.
AE normally takes a longer time because it samples a lot of imformation when animating – it provides finer movements than most editing systems.
Finally, don’t animated Position and Anchor Point if you can avoid it and they essentially do the same thing, ie move layers. It’s difficult to tweak the motion as you’ll be hardpressed knowing which of Position or Anchor Point to tweak.

Try rendering to Quicktime format using the Animation Codec. This codec preserves all of the original detail of your animation, but it is very space-efficient and will almost always result in smaller files.
As for the render time, that is a function of your computer specs, the codec you are rendering to, the content in your animation, how you set up the animation etc. so there is no way for us to troubleshoot this for you without substantially more detail on the above items.

I’ve done the “Star Wars” style opener a number of times. The easiest way to do that is to create the entire text as an image in something like Photoshop, rather than using the text tools in After Effects. After Effects tracks all that text as vector points, and if you’ve got a lot of letters, then you’ve got a lot of points to keep track of, etc.
However, in Photoshop you can pre-build the text layer and rasterize it so that it’s just pixels. Import it into AE as it’s own layer, and then turn on 3D layer. Rotate it on the X axis (X runs, left to right, Y up and down, and Z front to back) and then animate it travelling on Z. I guarantee you it will render faster.
As for the file size, I’m in complete agreement with my peers. You are probably rendering out at full-frame uncompressed AVI and depending on the length of the animation and the size of the video (SD or HD, etc.) the files can get huge. Full-frame uncompressed is advisable only if you are going to do further processes to the video (such as frame by frame editing, sound sync, etc.). If this is the “final” then render it to the codec for your output format.
