Hi,
I used this snipped in my python project were I needed the same thing:

from PIL import Image
from PIL.ExifTags import TAGS

def resize_image(path, name):
     size = 200, 200

     infile = os.path.join(path, name)
     outfile = os.path.join(path, "thumb_" + name)
     print outfile
     if infile != outfile:
         try:
             im = Image.open(infile)
             im.thumbnail(size, Image.ANTIALIAS)
             im.save(outfile, "JPEG")
         except IOError, ex:
             print "cannot create thumbnail for '{0}': 
{1}".format(infile, ex)


def handle_uploaded_file(f):
     with open(os.path.join(settings.MEDIA_ROOT, f.name), 'wb+') as 
destination:
         for chunk in f.chunks():
             destination.write(chunk)
         destination.close()
         resize_image(settings.MEDIA_ROOT, f.name)

It uses the python PIL module, which you should check out, it's pretty 
easy to use. No sure if it works for the video.
