Is this work to determine which MJPEG resolution presets are available in the release candidate of PTools? If so, I hope we see a range of settings to cover every type of anamorphic lens from 1.33x to 2x :)
EDIT: Now that PTool 3.62d supports MJPEG frame widths greater than 1920 pixels wide, the GH2 can be patched to support 2x anamorphic adapters natively in 4:3 VGA video mode. For 1.33X anamorphic adapters, HD mode provides native support as well. Videos shot in the following anamorphic frame sizes with the appropriate anamorphic lenses will be played back at the correct aspect ratio, and will not require post-production stretching:
