ublock origin works great using default settings, e.g., using popular freeware "obs studio" to record whole movies while displayed full screen in the browser, they play back normally without commercial interruption (but only short pauses
where those intrusive commercials were skipped, maybe a fraction of one second)

i like to use pale moon for this, but probably any browser that works with the ublock origin extension should work just as well, maybe even better ... try it for yourself and see (e.g. youtube, tubitv, etc.), movies, tv series, saved to
mp4 format for viewing on other devices, using obs "display capture" to record
streaming content while displayed full screen, e.g. in mozilla firefox uncheck "use recommended performance settings", and uncheck "use hardware acceleration when available"; obs "hide obs windows from screen capture" and software video
encoding (same as stream, x264) save streaming video (this method may not work with some "digital rights management" sources), and easily remux *.mkv to .mp4 . . .

Rendering on the video card, involves "planes", and desktop 2D, VMR7/VMR9, DirectX3D
could all be on separate planes. When a Hollywood video plays, the memory in the
video card that is used, is not accessible from the desktop, so capture should not work in that case. That is called PVP or Protected Video Path, and Microsoft
is pretty proud of that. As the signal leaves the PC, it can be protected
with HDCP 2.2 and so on.

Youtube videos don't absolutely have to be protected that way, and that
might be why capture attempts can work.

Unchecking "use hardware acceleration", might move a render from the 3D plane to the 2D plane, for example. Then, if the capture software only worked on
the 2D plane, your capture would work.

The "quality" of a capture varies. Screen capture is generally asynchronous, and involves reading dual or triple buffered software buffers. If the screen capture is running at "60FPS", yes, it is taking 60 samples in one second,
but some of the frames might get repeated due to not using VSYNC to coordinate the sampling operation. This means your capture is not a perfect copy.

Bad capture programs, the video and audio lip sync is not maintained, and
the capture is so bad, that if the lip sync is off, it is off by 0.5 seconds
at the beginning, 1.0 seconds in the middle, 0.25 seconds near the end. Attempts to use a video editor, to "shift" the audio time line back and
forth, will then fail to "align" the sound. You know you are dealing with
a top quality capture program, when a single correction to lip sync
yields perfect results at any point in the video. This is why a lot of people "fail at the task" of screen capture, as their video has poor control of
video alignment to audio (such alignment normally requires the usage of
"time stamp codes").

Out of my attempts to capture a Youtube like that, FFMPEG never does
a good job, but there was one other program that did work OK. When you
are trying things out, this is something to look for. You want to capture
a music video, where the faces of the singers are exposed in full view,
so you can review whether the audio sync later is perfect from one end
of the video to the other end. Then, only your async capturing will be
broken. I don't know of anything which triggers off VSYNC for capture.

above my pay-grade . . . even before using ublock origin, i'd been recording movies and tv series using obs studio with full-screen display (1920 x 1080) and it worked mostly fine, except for the predominantly wretched commercials that interrupt at the worst possible times (as if scripted for murphy's law)

the "mp4" format makes it easy to fast-forward through commercials and other undesirable material, most movies may worth seeing once but not worth saving, while some are so bad that after five or ten minutes of enduring it, deleted, but the really good movies and tv series that i've recorded (~3.5 to 4 stars) were saved to flash drives for future viewing, it works, and it's easy to do

since adding "ublock origin" to the three browsers that i typically use, the improvement has been magnificent (alfred hitchcock himself would've approved) and without commercial interruptions, movies, series, documentaries, youtube videos, etc. are far easier to enjoy . . . also for browsing websites, ditto
