    Hi all! I’m an AE on a new project just hoping to get some outside information. Our footage is shot 4k anamorphic (I believe on Arri). The raw footage is 2944×2160, so the unsqueezed image should be 5888×2160, right? So far it seems like the best way to continue about our workflow is to use FrameFlex to unsqueeze the video, but it looks like there’s some pillarboxing on the sides of the image when I do that in addition to the black bars on top and bottom. Does anyone know of a workflow that might eliminate those black bars on the sides? When I open the footage in something like QuickTime the pillarboxing isn’t there. Any help is appreciated!

    Hey Smith,

    One thing to keep in mind is that anamorphic footage is squeezed horizontally to fit the same aspect ratio as standard footage. When you use FrameFlex to unsqueeze the footage, it will stretch it back out to its correct aspect ratio. However, this can result in pillarboxing on the sides if your sequence is not set up properly.

    To eliminate the black bars on the sides, you may need to adjust the settings of your sequence to match the correct aspect ratio of the unsqueezed footage. This will likely involve adjusting the aspect ratio settings in your project settings or creating a custom sequence with the correct settings. You may also want to double-check that your FrameFlex settings are correct and not adding any additional pillarboxing.

    It sounds like you are on the right track using FrameFlex to unsqueeze the video. The pillarboxing on the sides could be due to a mismatch between the aspect ratio of the footage and the aspect ratio of your composition. You may want to double-check your composition settings to ensure that they match the aspect ratio of your unsqueezed footage. Another possibility is that there is additional cropping on the sides of the footage that is causing the pillarboxing. You could try adjusting the FrameFlex settings to see if that helps eliminate the black bars on the sides. Finally, you could try exporting the footage and see if the black bars are still present in the exported file
