Hi Kitten,
Actually, you need to specify the output folder AND the file name in the "output path" box. Qube's After Effects jobtype is based on the "aerender.exe" program that's supplied with After Effects, and the "output path" box corresponds to aerender's "-output" option.
For example, you can specify:
X:\projects\ae\images\myscene[####].tif
The [####] will be replaced by the frame number.
Instead of specifying the output path at submission, you can also specify it in the project's render queue. Just add your comp(s) to the render queue within aftereffects, and modify the output path in the render queue, save the file, and submit the project.
