Videos on most sites make use of progressive downloading, which means that the video is downloaded to my computer, and easy to trace. There are lots of extensions out there
Easy youtube-dl example on macOS (in the command line Terminal; Windows supported too):

copy link of ts
remove index and ts extension from link
for example:

will be copied as
http://vid.com/vod/mp4:vod/PRV/Yg0WGN_6.mp4/media_b180000
insert in below script under LINK
#!/bin/bash
# insert here urls
LINK=(

adding script in python - runs on windows and linux
import urllib.request

import shutil

lesson_dir = "my_vids"
try:
shutil.rmtree(lesson_dir)
except:
print "ok"
os.makedirs(lesson_dir)
os.chdir(lesson_dir)
for lesson, dwn_link in enumerate(my_lessons):
print ("downloading lesson %d.. " % (lesson), dwn_link)
file_name = '%04d.mp4' % lesson
f = open(file_name, 'ab')
for x in range(0, 1200):
try:
rsp = urllib.request.urlopen(dwn_link + "_%04d.ts" % (x) )
except:
break
file_name = '%d.mp4' % lesson
print "downloading %d.ts" % (x)
f.write(rsp.read())
f.close()
print "done good luck!! ================== "
if the script fails, or downloads empty file, try removing the try wrap to see what fails
With following script you can save movie to Videos folder

I needed to download HLS video and audio streams from a e-learning portal with session-protected content with application/mp2t
MIME content type.
Manually copying all authentication headers into the downloading scripts would be too cumbersome.
But the task got much easier with help of Video DownloadHelper Firefox extension and it's Companion App. It allowed to download both m3u8 playlists with TS chunks lists and actual video and audio streams into mp4 files via a click of button while correctly preserving authentication headers.
The resulting separate video and audio files can be merged with ffmpeg:
ffmpeg -i video.mp4 -i audio.mp4 -acodec copy -vcodec copy video-and-audio.mp4
or with mp4box:
mp4box -add audio.mp4#audio video.mp4 -out video-and-audio.mp4
Tried Video DownloadHelper Chrome extension too, but it didn't work for me.
