The Work Area is critical for certain preview options. It is used as the default in/out points stipulated in the Render Queue’s Output Options. You can safely override the default in/out points.

You shouldn’t want to tweak the green’s unless its meant to help in the keying process … . So, it’s best to key first then grade the footage.

I’m glad things have worked out for you. I suggest that you practice more often – 1 to 2 tracks each day; starting with easier tracks and then building on your skills with more difficult tracks.

Try the following steps:

1) Track the ground area using either mocha or AE’s Motion Tracker or even AE’s 3D Camera Tracker.

2) Apply the results to a Null Layer.

3) Create a Solid and apply Particular

4) Parent the Solid to the Null

5) Keyframe (or track) Particular’s Emitter position to follow the ball.

Stabilize the shot with Warp Stabilizer. This single step will solve two issues for you (1) shaky footage (2) lock down your particles.

To get Particular to emit its particles earlier, set the Pre-run property (Emitter section) to a positive value – start with a value of two seconds and adjust to taste.

Hi Simon, I’m glad you’ve got results that suit your needs. As for the question, it’s a requirement that the insert clip share the same size as the tracking footage. Therefore, if your insert clip is of a different size, you should then resize it in a precomp. This isn’t a mocha tracking data requirement but rather a manifestation of how the Corner Pin effect works.

There are actually two parts to the Corner Pin effect – (1) start points and (2) end points – for each of the four points. The end points are where mocha’s tracking data ends up. The start points default to the size of the comp or the size of the tracking footage. Most users fail to see the importance of the start points and this is a great cause for confusion. If you take a look at the CC Power Pin effect, it has separate start and end points that are shown clearly.
This helps to overcome a lot of the confusion as well as allowing a user to resize the insert clip via the start points. This precludes having to precomp/next the insert clip.

I’m not sure about the second question as I’ll have to take a look at all the variables before I can be certain of the issue.

Go to your Preferences dialog and within the Preview section change the Audio Preview duration to an appropriately length.

Ensure that your insert clip fits the tracking footage’s comp size – by this I mean that your insert clip not only has to reside in a comp which is of the same size as the tracking footage BUT the insert clip’s edges has to hug the perimeter of the comp.

You can do this simply/quickly by selecting the footage and hitting the CTRL+ALT+F – of course do this in the precomp.

BTW, I am assuming that you’ve got a good looking track in mocha, ie no more bumps and such?
