General rules:
$ inigo -group in=0 out=49 clip* -group -filter greyscale
+Attached Filters:
+
+ As described above, the -filter switch applies filters to an entire track. To
+ localise filters to a specific clip on a track, you have to know information
+ about the lengths of the clip and all clips leading up to it. In practise,
+ this is horrifically impractical, especially at a command line level (and not
+ even that practical from a programing point of view...).
+
+ The -attach family of switches simplify things enormously. By default, -attach
+ will attach a filter to the last service created, so:
+
+ $ inigo clip1.dv clip2.dv -attach greyscale clip3.dv
+
+ would only apply the filter to clip2.dv. You can further narrow down the area of
+ the effect by specifying in/out points on the attached filter.
+
+ This might seem simple so far, but there is a catch... consider the following:
+
+ $ ingo clip1.dv -attach watermark:+hello.txt -attach invert
+
+ The second attached filter is actually attached to the watermark. You might
+ think, yay, nice (and it is :-)), but, it might not be what you want. For example
+ you might want to attach both to clip1.dv. To do that, you can use:
+
+ $ ingo clip1.dv -attach-cut watermark:+hello.txt -attach-cut invert
+
+ As you shall see below, there are still another couple of gotchas associated to
+ -attach, and even another variant :-).
+
+
+Mixes:
+
+ The -mix switch provides the simplest means to introduce transitions between
+ adjacent clips.
+
+ For example:
+
+ $ inigo clip1.dv clip2.dv -mix 25 -mixer luma -mixer mix:-1
+
+ would provide both an audio and video transition between clip1 and clip2.
+
+ This functionality supercedes the enforced use of the -track and -transition
+ switches from earlier versions of inigo and makes life a lot easier :-).
+
+ These can be used in combination, so you can for example do a fade from black
+ and to black using the following:
+
+ $ inigo colour:black out=24 clip1.dv -mix 25 -mixer luma \
+ colour:black out=24 -mix 25 -mixer luma
+
+ while this may not be immediately obvious, consider what's happening as the
+ command line is being parsed from left to right:
+
+ Input: Track
+ ----------------------- -----------------------------------------------------
+ colour:black out=24 [black]
+ clip1.dv [black][clip1.dv]
+ -mix 25 [black+clip1.dv][clip1.dv]
+ -mixer luma [luma:black+clip1.dv][clip1.dv]
+ colour:black out=24 [luma:black+clip1.dv][clip1.dv][black]
+ -mix 25 [luma:black+clip1.dv][clip1.dv][clip1.dv+black]
+ -mixer luma [luma:black+clip1.dv][clip1.dv][luma:clip1.dv+black]
+
+ Obviously, the clip1.dv instances refer to different parts of the clip, but
+ hopefully that will demonstrate what happens as we construct the track.
+
+ You will find more details on the mix in the framework.txt.
+
+
+Mix and Attach:
+
+ As noted, -attach normally applies to the last created service - so, you can
+ attach a filter to the transition region using:
+
+ $ inigo clip1.dv clip2.dv -mix 25 -mixer luma -attach watermark:+Transition.txt
+
+ Again, nice, but take care - if you want the attached filter to be associated
+ to the region following the transition, use -attach-cut instead.
+
+
+Splits, Joins, Removes and Swaps:
+
+ COMPLEX - needs simplification....

Introducing Tracks and Blanks:
So far, all of the examples have shown the definition of a single
Reversing a Transition:
- When we visualise a track definition, we also see situtations
+ When we visualise a track definition, we also see situations
