trying to change a .mov file to .mp4 when uploading it - python/django

First time asking a question here... SO,

I have a django web app where people can upload video files. The video file upload just fine and when they are .mp4 files, they can click on them and immediately play them in the chrome browser. However, if the video file is .mov, it forces the user to download the file to their computer before viewing it. I have tried to capture the file before is saves and change the filename from .mov to .mp4 but its not working. 

form = AddAttachmentForm(request.POST, request.FILES)
if form.is_valid():
    attachment = form.save(commit=False)
    attachment.user = student
    attachment.attacher = self.request.user
    attachment.date_attached = timezone.now()
    attachment.competency = competency
    attachment.filename = request.FILES['attachment'].name
    if attachment.filename.endswith('.mov'):
        attachment.filename.replace('.mov','.mp4') 
 attachment.save()

This way you are just creating an extension.mov.mp4

use os.path.splitext(), os.rename()

import os
thisFile = "mysequence.mov"
base = os.path.splitext(thisFile)[0]
os.rename(thisFile, base + ".mp4")

Try using this:

import os

form = AddAttachmentForm(request.POST, request.FILES)
if form.is_valid():
    attachment = form.save(commit=False)
    attachment.user = student
    attachment.attacher = self.request.user
    attachment.date_attached = timezone.now()
    attachment.competency = competency
    filename = request.FILES['attachment'].name
    ext = os.path.splitext(filename)[1].lower()
    if ext == '.mov':
        attachment.filename = os.path.splitext(filename)[0] + '.mp4'
    else:
        attachment.filename = filename
    attachment.save()

This should change the file extension as you want, but I don't think changing extension have any effect for browser, because it will check the mime type as well.
