OpenFX: Add anamorphic squeeze ratio support

[yshui1]

Add configurable anamorphic squeeze ratios for OpenFX and Adobe plugins.

• Add preset and custom squeeze-ratio parameters
• Publish the calculated crop guide through SqueezeBorder
• Preserve raw rendering without de-squeezing
• Adjust anamorphic output fitting to avoid unwanted zoom
• Update version metadata to 2.2.0
• Document the new workflow and add release notes

Why do you need this? You should set your anamorphic ratio in your editor (Resolve or Premiere) and Gyroflow has "Disable gyroflow's stretch" if your lens profile was calibrated with the stretch

I'm not adding desqueeze function to it. I mainly updated the logic used to auto-crop the footage.
I don't know if you ever tried with 1.5x anamorphic lens footage shot on 16:9 format and edit on 2.4:1 ratio timeline. The current version of Gryoflow OFX doesn't work properly. The main issue is that it cannot correctly auto-crop in when raw footage is much wider than the timeline resolution after desqueeze. It crops way more than needed. I'm making a tutorial that will explain this better.

anamorphic footage definitely works with current plugin. You should set the correct desqueeze in Resolve and toggle the "Disable gyroflow's stretch" in the plugin and that's it

If you also change the timeline aspect ratio, then you have two additional ways described in the docs

Unfortunately, it doesn't work.
Here is an example of using scale image to fit.
Source footage shot with 1.6x anamorphic lens in 16:9 format, 3840x2160
Timeline resolution: 5184x2160 (2.4:1 ratio)
Before

After

I cannot get the correct output ratio I need.

I would not want to work on the Fusion page since that makes things complicated.

My new workflow is to set project Input Scaling to "Scale full frame with crop"
Do not desqueeze the footage in the attribute
Apply Gyroflow and set Input Squeeze Ratio to 1.6x (Default 1.0x which works exactly like before, good for any spherical lens footage)
Apply Desqueeze in any node after Gyroflow by using the Transform effect, setting width to 1.6
Done
