Edit: I do not maintain this script anymore, dgorissen forked this and made it better – https://github.com/dgorissen/coursera-dl
After taking two Coursera classes(db and algo), I wanted a simpler way to download the lecture assets(video files, pdf, ppt etc) from the site.
The features that I was looking for in the downloader:
1. Bulk download from the command prompt.
2. The downloader should recreate the structure present in the video listings page i.e it should create directories corresponding to each weekly topic and their sub topics and download the files into the appropriate directories.
3. The downloader should be smart as in when it is run each time from the command prompt, it should know the assets previously downloaded and download only the newly updated assets. Speaking in programmer terms, it should diff between all the previous downloads and the assets in the current page and download only the newly added ones.
Hence, my free time during the last few days were dedicated to scripting this. The Python script that I wrote for this can be downloaded from github. Extract the contents of the zipped file to the directory where you want the assets to be downloaded and run the python script. More info is present in the readme.txt file accompanying the script. The script recreates the structure present in the video listings page and downloads the assets to the appropriate directories.
The image below shows the directories created and some of the files downloaded for automata course.
Compare the above with the course structure present in the video listings page of automata course:
Whenever new lessons are posted, just run the script and the script takes care of downloading the updated contents. It keeps track of already downloaded files and hence only downloads the newly updated contents.
Give it a spin and let me know how it works for you.

Hi,
I have also created an APPYnote room for HNers who are on Coursera…feel free to join in:

Thanks for your work. I found one “bug”. Try to download CS101 and you’ll receive this message:
Downloading resource – https://class.coursera.org/cs101/wiki/view?page=code-1
Traceback (most recent call last):

CS101, in it’s asset list, has a link to the wiki which is not a downloadable content. That is why the script is barfing. Let me see what I can do to fix this.
Have fixed this now. Grab the latest download.

Thank you for this excellent piece of software. I have found it most excellent, and it appears to work for almost all cases, except for one.
For hci-class.org, there is a bug with downloading one of the recent lectures:
Downloading resource – https://d19vezwu8eufl6.cloudfront.net/hci/slides_pdf%2FHCI-05-2-HeuristicsFirstHalf.pdf

with open(fileName, mode) as fp:
IOError: [Errno 2] No such file or directory: ‘5 – 2 – Lecture 5.2 Design Heuristics (Part 1/2) (2002).mp4’
The reason is because there is a “/” in the filename which causes the script to create a directory within a directory, at least on MacOS X, which causes the rest of the script to choke up.
Have fixed this. Grab the latest download.

I have been downloading compilers class and it works very well for me. If you do not mind sending your coursera credentials, mail it to me at abhyrama at gmail dot com and I will try to see what is going wrong.
Thanks dude …
I think the problm is with my system n i am sending my credentials to u,plz check n tell me dat u hv received or not
thnks again..
I tried with your creds and it works for me. Are you behind a proxy? I do not think it will work behind a proxy.
i dont thin so …
i’ll try it again
@abhirama- dude i formattd my ubuntu 12.04 n installd new but the same ubuntu 12.04…
its working for me now…
thnks for the help….
dude ur work is very good..
just a random idea dat why dont u try to make a chrome extension to download coursera videos…
it would also be good for evry1
There must be an extension for chrome that lets you download all downloadable content in a page. There is one for FF.
Worked on Ubuntu, but the script bugged out on my windows machine for the HCI class.
Do you have an error trace by any chance?
I find that it is not working today, it used to work previously flawlessly. I can see the login is not happening as login page is not found.

Thanks a bunch.
I just discovered your script a couple weeks ago and have been using it ever since – apart from today, it has been working perfectly and I really appreciate your taking the time to make it public. (I’m also receiving http 404 errors and the same traceback as mohit at the moment. Haven’t had time to investigate any further.) In any case, thank you so much!
This has been fixed thanks to https://github.com/itelichko. Grab the latest download.
This works now. Thanks for you hard work and your fast reaction.

Also with this class the problem is, since the teacher didn’t give names like : lecture 1-1, lecture 1-2 all the files aren’t sorted at all.
Again thanks for your job.
Looks like there is a problem with the asset itself. Try downloading the pdf of Discrete probability in week one. I am getting a forbidden error.
Have fixed taken care of this situation. Grab the latest download.
Help, I’ve been informed and I can’t become igornant.

As a sanity check, this course DID work for me: https://class.coursera.org/algo-2012-002/lecture/index
Hi, great work ā thanks. I have successfully used it for some of courses, but it fails on Algorithms I and Gamification. There are no exceptions or errors reported, it just says that it got all downloadable content and exits ā but hasnāt actually downloaded anything.
Sorry, please ignore — problem existed between keyboard and chair š
Worked perfect, but now I am getting a 430 Forbidden error.
Yep, same here since this morning… It fails on https://www.coursera.org/maestro/api/user/login
I am trying to download the “Algorithms, Part I” material and immediately get a forbidden error. Can you please take a look at this?
Fails to download…

Any updates on this? Looks like the user api has changed.
I am getting same error as krishna for all courses. š¦ Can you please fix?? š¦
May you please give a step by step procedure? I don’t know anything about programming. thanks
The login API of coursera has changed. See
https://github.com/dgorissen/coursera-dl/commit/fe9dd7d8fcf147692d3bf137993b424806911e17
for a sister project that already implemented a fix. Not sure whether this can be adapted to this project. And whether abhirama is willing to fix the script (would be nice though).
Fix incorporated here: https://github.com/dgorissen/coursera-dl
Thanks for making the code available. I cleaned it up, added some features and made it available as a python package: https://github.com/dgorissen/coursera-dl
Thanks for doing this, I will update my blog post to reflect this.
@dgorissen: does this work in the same way or there is different set of procedure that need to be followed to download the lecture? ‘m scared if it’ll mess with my existing lecture folder? Downloaded content would follow the same folder naming convention or did you change that too?
It works in the same way. However, I did ensure a numeric prefix always gets added the class directories to ensure the order of the directories is always chronological (otherwise it often isnt). This means that it will re-download everything in your case (but never remove anything that was not there). I suggest you simply try the script in a new test directory and see if you are happy with what it does.
@dgorissen: Thank you so much!! š By the way ‘m downloading current python lectures š and most probably I’ll also be able to tweek the code according to my need after I finish it. Thanks again to make it working. š
No probs š please do share back any changes you make.
@dgorissen: Yes I’ll definitely do if I make anything good. ‘m OpneSource lover! š
Hi:
I have troubling downloading contents from coursera.org. According to the readme.txt file, I took the following actions.:
1. Download python3.3 from http://www.python.org/ and install it
2. Extract coursera-download-master and open download.cfg with notepad, enter my username, password and class link
3.Open Python (command line) from all programs:
then navigate to the directory where you extracted download.py and download.cfg and type ‘python download.py’. and type in the following code in the python command line
>>>python download.py
4.I got an error:
File “” , line1
python download.py
SyntaxError: invalid error
(I don’t know how to use python at all, I just read some information from websites)
Thanks
I do not maintain this any more. Please check this out – https://github.com/dgorissen/coursera-dl.

You may also use Allavsoft which can easily and batch Download Videos from Coursera to MP4, AVI, WMV etc
Or you can use a perl script at https://metacpan.org/pod/WWW::Coursera
I also have the need to download Coursera course video lectures.
Then I google searched and test so many so called Coursera Downloader.
Finally and luckily, I find Allavsoft which does works great in download all videos lectures from coursera.
Why not just give it a try?
According to my experience, it also helps to download video courses from Lynda, Udemy, Tutsplus, Digital Tutors, CruncyRoll, Pluralsight etc.
Hope it also helps for you.
