Interleaving Fields

The interleave standalone merges pictures together by interleaving their fields (scan lines).

The interleave standalone allows you to accomplish the task of interleaving picture files outside the interface. You can also perform this task from within the Autodesk Softimage interface using the built-in interleave function.

For more information on interleaving fields within Softimage, see Field Rendering [Rendering].

Usage

interleave <input file 1> [<input file 2>] 
<output file> [-e | -o | -i] [-f] [-r <repeat count>] [-s <start frame> <end frame> <step>] [-v]

Where <input file 1> is the name of the first picture and <input file 2> is the name of the second picture. This parameter is optional when using the -s option. <output file> is the name you want to give to the result.

By default, the first scan line of the output file is the first scan line of the first input file. You can change this by specifying the options [-e | -o | -i].

Options

-e	Uses the first scanline of the input picture containing the even fields for the first scanline of the output.
-o	Uses the first scanline of the input picture containing the odd fields for the first scanline of the output.
-i	Can be used only when both a single input file is given and the -s option is specified. If this option is used, the first scanline of the even-numbered frames becomes the first scanline of the output. If this option is not used, the first scanline of the odd-numbered frames becomes the first scanline of the output by default.
-f	Reads field frames (such as default.1.1.pic, default.1.2.pic).
-r	Specifies how many times each frame should be repeated. The default is 1.
-s	Interleaves a sequence of frames. If only one input sequence name is given, the odd-numbered scanlines of the odd-numbered frames interleave with the even- numbered scanlines of the even-numbered frames (assuming you start with scanline 1, not 0, and the step is 2). For example, the odd scanlines of frame 1 interleave with the even scanlines of frame 2, similarly for frames 3 and 4, and so on. In this way, a sequence of 100 frames becomes a sequence of 50 frames.
-v	Activates verbose output.

Example

For example, to interleave the image house1 and house2 from frames 1 to 300 with a step of 2 (-s 1 300 2) with the resulting image called houses, you would type:

interleave house1 house2 houses -s 1 300 2

The name of the second picture is optional when using the -s option.

Here is another example which interleaves the files spherelayer1 and cylinderlayer2 with the resulting output as movecomposite. The operation is done from frames 1 and 100 with a step of 1, the field frame (-f) is read, and verbose mode is on (-v).

interleave spherelayer1 cylinderlayer2 movecomposite -s 1 100 1 -f -v
