DataManager compatible Extraction script

[parsa-ra]

Hey Tobias,

First of all, I want to congratulate you on your awesome work ...
I am wondering if you can share the script which turns the default distribution of the dataset (i.e., mp4 files without extracted .png to the multi-view images, colmap and alpha) to the version that is supported by your datamanger?

As an other idea, I think it would be nice to being able to extract the images and alpha maps on the fly from the mp4 files directly instead of storing them ... let me know if I can help you with this

Thank you
BR
