You asked this about 3 weeks ago as well (and replied to that email
today), did this approach not work?:

This is explained in the docs for FileField, you need to create a
django.core.files.File subclass, and save() it on the FieldFile object
that is returned when you access the FileField field on your model
instance.

Eg:

from django.core.files import File
fp = open('/path/to/file')
myfile = File(fp)
my_obj.mp4_720.save(name="....", content=myfile)

https://docs.djangoproject.com/en/1.8/ref/models/fields/#django.db.models.fields.files.FieldFile.save
