So mp4_480 and mp4_720 should be blank=True and null=True. And then pass
the video instance object to the delay() ???
And also, could you please show me how to write the tasks.py, so that I can
use ffmpeg code (subprocess.call('ffmpeg -i path/.../original
path/.../mp4_720') to transcode.
Thank you.
