I think there may be something a bit wrong with this session. I have had 21 invalid tasks come out of it (out of less than 100 tasks), whereas I have previousuly gone months without having a single invalid task (The entirety of session 3107, for example). A random sampling of other completed tasks seems to show that mine is not an isolated example.

I'm not yet savvy enough to be able to figure out what the issue might be (this is my first post!), but I thought I might bring it to someone's attention, and at the very least learn something from it.

This is a project by my 12 year old son. This is the first time a project has been sent to BURP so there certainly could be errors with the source project or the submission process. He believed he had created the correct format for submission, and although we were unclear on some of the questions during the submission process, it seemed to take. If there is something to be learned, we would definitely appreciate input.

Thank You.

A couple of hints for future improvement:
1) The renderfarm doesn't render the sound, so you can save a bit on the file size by not including a WAV file
2) Visual noise needs to be consistent between individual renders of the same frame. You can make sure of this by making the noise deterministic (through the settings in the .blend for the camera or the texture using/making the noise) and/or make the sampling high enough that the noise almost disappears
