to create at the end of the path. Make sure not to overwrite the path.
You are going to render a file sequence instead of a movie file such as a QuickTime file.
File sequences are generally faster for Nuke to process as Nuke doesn't have to unpack
the whole movie file to load in just one image.

Naming file sequences
There are two ways to render moving images. One is by rendering a single file that holds
all the frames, as is the case with QuickTime and AVI. The other, which is preferred
for various reasons, is the file sequence method. In this method, you render a file per
frame. The way you keep the files in order is by giving every file a number that cor-
responds to the number of the frame it represents. This creates a file called something
like myrender.0001.jpg, representing the first frame of a sequence. Frame 22 would be
myrender.0022.jpg. And so on.
When you tell Nuke to write a file sequence, you need to do four things:
• Give the file a name. Anything will do.
• Give the file a frame padding structure —as in: How many digits will be used to
count the frames? There are two ways to tell Nuke how to format numbers. The
first is by using the # symbol, one for each digit. So #### means four digits, and
