Short answer: a Threads video downloader for PC, a Reddit video downloader for Mac, and their equivalents for Pinterest, LinkedIn and Tumblr all come down to the same three moves — open the post where it plays, capture what the page fetches, save the highest rendition locally. What differs is where the video lives (post, embedded frame, or linked host) and whether a login is needed to see it at all.
The five, side by side
| Platform | How video arrives | Practical friction |
|---|---|---|
| Threads | Uploaded clips rendered as progressive media in the timeline | Autoplay starts on scroll, so the request exists only briefly; capture while it plays |
| Hosted clips, plus a large share of posts that embed an external site's player | You must target the media host, not the reddit post page, on embeds | |
| Idea Pins and video pins served as renditions | Player UI hides the media layer; the address is in requests, not markup | |
| Uploaded video for feed and, for some pages, longer-form streams | Most content sits behind a login, so a session-capable tool is the difference between a list and an empty result | |
| Tumblr | Native video posts and GIF-like loops | Legacy posts embed third-party players, so the media may belong to another origin |
One capture method that covers all five
Open the post where it actually plays
Not a share page, not a preview: the view in which video moves. For logged-in networks, use the browser profile carrying your session, or sign in inside the desktop app's own view. LinkedIn in particular will show nothing useful anonymously.
Make sure the media has been requested
Let it play through. Reddit embedded players and Tumblr legacy embeds fetch only when their frame becomes visible, so scroll to the post rather than analysing the page top-down.
Capture from the frame that owns the media
When a post embeds another site, the outer page holds no media at all. Either point at the frame's document URL or let the tool watch the whole tab — the embed mechanics are explained in downloading embedded video.
Save the best rendition without converting
Pick by resolution and bitrate; keep the file as delivered. The selection rules are in highest-quality downloading, and if audio arrives apart, merging the two tracks is a copy operation, not a conversion.
Note the source
Record the post URL and author. Reddit and Tumblr in particular rehost and delete content, so provenance is what lets you find the original later.
Platform-specific notes worth knowing
- Reddit: distinguish hosted clips from embeds. A hosted clip behaves like any progressive media page; an embed belongs to the source site, and its terms travel with it.
- Threads: as an Instagram-adjacent product it inherits similar encoding behaviour, so expect a rendition ladder rather than a single master. Instagram's own delivery quirks are on the Reels page.
- Pinterest: vertical framing is the norm — verify aspect ratio after saving rather than assuming the player's crop was the file's.
- LinkedIn: professional content is often someone's work product. Saving a clip you can view is a personal-reference act; circulating it inside or outside your network is a rights question.
- Tumblr: loops saved from older posts are frequently GIF-derivative video with no audio track at all — an absent audio stream is expected there, not a failed download.
What stays out of scope
Private groups, followers-only posts, age-restricted content and anything requiring an entitlement your account lacks are outside this method — that is access control, not a technical obstacle. Protected delivery is likewise outside everything described here. And on every one of these platforms the creator's copyright and the site's terms apply to what you do with a saved file, so publishing someone else's video needs permission, not just a working download.
FAQ
Is there a Threads video downloader for PC?
Yes — a desktop app that plays the post in your session and saves the rendition the page requested, with no extension installed.
How do I use a Reddit video downloader on Mac?
Open the post that plays the media, capture what the page fetches, and save the top rendition. On embedded Reddit posts, target the frame's source site instead.
Can I download Pinterest video on Windows?
Yes. Idea Pins and video pins are delivered as renditions; check the aspect ratio after saving since the player may crop.
Does a LinkedIn video downloader need a login?
Almost always, in effect. Most LinkedIn media is not served anonymously, so the tool must operate with your session.
Why is there no audio on a Tumblr video I saved?
Many Tumblr loops are silent by nature. Check whether the source itself had audio before assuming the download failed.
Can I download from a private group on these platforms?
Only content your account can view. Restricted access is a boundary this method does not attempt to cross.
