Rendering pain
Hi, I am putting together my showreel in AE and my renders keep on failing. PC specs below.
I began thinking it was because of some kind of ram issue and have tried the secret prefs purge option described in various past posts, trying everything down to 1 frame, with no effect*. So I rendered what I could expecting to be able to assemble all of the bits in one final comp and render them off free from heavy effects and memory issues and have now managed to get to the point where all I need to render are the resulting chunks of mov files and tiff sequences.
However my problem still persists. I thought it was perhaps the fact that a mov file I am trying to render failed and so is corrupt but I have a screen grab of my render queue, timeline and error msg which shows that each time the render fails at exactly the same frame. Easy you think, theres an effect, layer or corrupt mov coming in at that frame which is causing the problem. Unfortunatly thats not the case, the mov has been rendered and no new layers come in at the offending frame as you can see from the screen grab. I can assure you that no effects whatsoever have been added to any of the layers in the comp so this too can be ruled out. I rendered the first 2 in the queue as uncompressed movs and the third as an avi. I am currently rendering again to see if the log can tell me anything.

Im on a 32bit Vista laptop, Intel core 2 duo, 2.20GHz, 4GB RAM, Rendering to a decent external HD with tonnes of free space.
*I understand this menu is hidden because the options slow rendering down as you would expect a purge to do, however after every say 10 frames if this is what i had entered in the box I wouldnt see any pause while frames were purged, is this normal? Maybe this is where my problem lies?

As you can see on the screen grab there are two visible layers, the first is an uncompressed mov, and the second is a tiff seq so no compression there. Could you advise me atall on any settings you would tweak in the memory prefs?

You’re getting a write error, so I’m guessing it’s not actually a RAM problem. I’ll hazard a wild guess: is your drive formatted FAT32, and your render failing when the movie hits the 4GB mark?
If that’s the case, you could either render to an image sequence, or convert the drive to NTFS.

Thankyou Walter, it sounds as if you have hit the nail on the head. My drive is FAT32 and yes each file ends up as 3.99Gb (should have spotted that one!). I’l get to looking in to sorting this out and i’l post to let you know how i get on.
Thanks again for all the help

Brilliant, thanks Walter your solution worked a dream. I rendered to a different drive which was NTFC. Thanks for your helpfull advice Dave too.
Now to reformatting my drive.

Adam, I’m glad to hear my suggestion worked.
There’s no need to reformat your disk. Windows can convert a FAT16 or FAT32 disk to NTFS non-destructively. Just a note — once you convert to NTFS, you cannot convert it back to FAT; if you wanted to make the disk FAT again, you’d have to reformat.
Just open a command prompt (Start > All Programs > Accessories > Command Prompt) and enter the following:
convert Z: /fs:ntfsOf course, change the drive letter as necessary on your specific system.

So is this safe to do? Would it be wise to back everything on the drive up or would that not be needed?

Well…. it’s always wise to back up everything on the drive, but I’ve never seen a problem with
convertmyself.Here’s the Microsoft support article for more information.
