Requesting help downloading these Richard Feynman lectures

[hatchling]

I'm stumped. I believe the video and audio streams come in fragments. I don't think they are encrypted (at least not in a way that requires a Content Decryption Module).

I'd love to have these lectures in 1080p quality and I'm worried they'll be taken down at some point. Can someone please help? There are 7 lectures in all.

Thanks in advance for any assistance.

Use youtube-dl with the following command lines:

Oh, at least some of those will result in the same filename so you can't run all of them in one batch file. Either download one at a time and rename, or add an output filename spec to each line. For example:

I'm downloading them now with that batch file.

jagabo, thank you so so much. It's working perfectly. I had no idea youtube-dl could handle this sort of thing.

hi guys!
i found this thread a while ago, downloaded the videos, but only now got around to watching them, and realised i don't have subtitles for them. english is obviously not my first language, and i have a problem with processing speech anyway, and those two combined mean i usually watch everything with english subtitles. so my question is: is there any way to download the subtitles as well? i checked project tuva, and they're there. i'm just not very good at this type of thing (video/online stuff), so i would appreciate your help. thanks in advance, and sorry if i'm breaking any of the forum's posting rules, or etiquette or i don't know. i hope i'm not.

Use a web browser's Developer Tools and watch the network traffic while the page loads. You'll see links to the vtt files:

thank you so much, jagabo! both for the links, and for pointing me in the right direction, so i'm now able to learn something new. today, i both got some fish, and i was taught how to fish.

I improved the above script to get each video with its corresponding subtitle file plus a text description with matching (and corrected/completed) names.
Requires youtube-dl and curl.
Feynman.bat.txt
If anyone else wants some fine and funny fysics fish...

(Currently running it, hope I made no mistake.)

EDIT : For those who prefer smaller fish, here's a modified script to download the videos in 960x720 at 3400kbps (instead of 1440x1080 at 6000kbps), which should be plenty enough considering the quality of the source footage and the nature of the videos (actually the quality is very similar even after resizing – see screenshots below). At this setting, each ~55min video has a size of ~1.37GB, and the total size is about 10GB (it would be almost double that in 1440x1080).

When I download the files using youtube-dl through terminal I get the file extension as ismv. I am not able to open these files. So how do I play them.
