Hi, I use a Macbook Pro and run Mac OS X. I'm having a problem with AE. I am trying to render a composition and I am receiving this error message when I try to render it:

After Effects error: Rendering error while writing to file “/Users/(my name)/Comp”. Unable to open file. (-1610153459)

I am doing nothing different from what I always do when editing and rendering in AE. The only clue that I have so far is that all my MP4 video files have a white sheet of paper as their icon. I don't think this is normal as they should probably show the little Quicktime Movie icon instead. But, regardless, I put the file into AE, it played perfectly normally, I did my editing, and then when it came to the render, I got this error message. I have tried restarting my computer and everything.

You haven't said what version of OSX you're using, or what version of AE you're using. Any chance you've updated quicktime recently?

Another possiblity is that you're experiencing AE weirdness associated with MP4 files. If you're running CS4 or earlier, take note of Dave LaRonde's
Dave's Stock Answer #1:

If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.

These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.

In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
And Adobe agrees.

That all being said, however, if this type of footage has worked for you in the past, it's more likely that something has changed. What hard drive are you trying to render to? How full is it?
