Video conversion for anamorphic shooters

Gitlab Project: https://gitlab.com/hellraz0r/ffmpegPrePostScriptsForOSX

In case you shoot anamorphic and want to go for a certain aspect ratio... For now, just if you are running on OSX...

(also works for non anamorphic footage with a scope ratio of 1)

Did you ever shoot in 16:9 but want to go into editing in a 2.7:1 AR?

The following shot was taken with a 2x scope in UHD on a GH4

Original shot

You can use this script to converted any Video readable by ffmpeg (so mostly all execpt RAW formats) to any target aspect ratio and transcoded it into ProRes or h264 in one step.

All these are grabs from Video. Please feel free to start a conversation, if you want to participate in the coding, testing, using!

For convenience, all is packaged in a ZIP File. Linux users should be able to unzip and use it from there.

This is my first git project, so please be nice ;)

2.7 Aspect Ratio

converted to 2.7 AR./convert.sh testfile.mp4 2.7 2

2.35 Aspect Ratio

converted to 2.35 AR./convert.sh testfile.mp4 2.35 2
