‌Outputting the Shot

You can write it out to disk using the Save Sequence button on the Output tab. It is also possible to save the sequence through the Perspective window’s Preview Movie capability.

Each method has its advantages, but using the Save Sequence button will be generally better for this purpose: it is faster; does less to the images; allows you to write the 16 bit version; and allows you to write the alpha channel. However, it does not overlay inserted test objects like the Preview Movie does.

Important : when writing stabilized 16-bit or floating-point images, be sure that the Process bit depth and Store bit depth on the shot parameters dialog is set

appropriately. The default settings reduce footage to 8 bits for tracking; you need to set it back to get the full bit depth out.

You can use the stabilized footage you write for downstream applications such as 3dsmax and Maya.

But before you export the camera path and trackers from SynthEyes, you have a little more work to do. The tracker and camera paths in SynthEyes correspond to the original footage, not the stabilized footage, and they are substantially different. Once you close the Image Preprocessor dialog, you’ll see that the trackers are doing one thing, and the now-stable image doing something else.

You should always save the stabilizing SynthEyes scene file at this point for future use in the event of changes.

You can then do a File/New, open the stabilized footage, track it, then export the 3-D scene matching the stabilized footage.

But… if you have already done a full 3-D track on the original footage, you can save time.

Click the Apply to Trkers button on the Output tab. This will apply the stabilization data to the existing trackers. When you close the Image Prep, the 2-D tracker locations will line up correctly, though the 3-D X’s will not yet. Go to the solver panel, and re-solve the shot (Go!), and the 3-D positions and camera path will line up correctly again. (If you really wanted to, you could probably use Seed Points mode to speed up this re-solve.)

Important : if you later decide you want to change the stabilization parameters without re-tracking, you must not have cleared the stabilizer. Hit the Remove f/Trkers button BEFORE making any changes, to get back to the original tracking data. Otherwise, if you Apply twice, or Remove after changes, you will just create a mess.

Also, the Blip data is not changed by the Apply or Remove buttons, and it is not possible to Peel any blip trails, which correspond to the original image coordinates, after completing stabilization and hitting Apply. So you must either do all peeling first; remove, peel, and reapply the stabilization; or retrack later if necessary.
