These videos are retarded and full of compression, poor quality, manipulation, motion blur, gamma issues, black levels, poor resolution with artifacts, morphing, and general video characteristics that the OP doesn't understand. Or are we just being trolled out of boredom? Go find a reptilian, tie it up and make some 4k@60 vids. Otherwise didn't happen
watch it, you've used the word "retarded", so you can bet someone here will go full retard. i won't point a finger, blurred or not.

Always thought it strange how the compression artifacts seem to only be localized to skin. Like never the clothes or surrounding frame. a reply to: eraTera
Three types of pictures (or frames) are used in video compression: I, P, and B frames.
An I‑frame (Intra-coded picture), a complete image, like a JPG or BMP image file. P and B frames hold only part of the image information (the part that changes between frames), so they need less space in the output file than an I‑frame.
A P‑frame (Predicted picture) holds only the changes in the image from the previous frame. For example, in a scene where a car moves across a stationary background, only the car's movements need to be encoded. The encoder does not need to store the unchanging background pixels in the P‑frame, thus saving space. P‑frames are also known as delta‑frames.
A B‑frame (Bidirectional predicted picture) saves even more space by using differences between the current frame and both the preceding and following frames to specify its content.

there's a name for constant repeating the same stuff over and over again. it's called spamming.
also, is that all you can do? posting the same pics - which you were told many times aren't what you claim them to be - over and over again, ad nauseam? if you think someone will agree with you just because of your persistence - you're wrong. endless repeating of BS doesn't change the fact it's still BS.

Look how frames are compressed and stored only DIFFERENCES between frames so if the background doesn't move that information can be used for other frames to reduce file size, and what is most likely to be moving that you mention .
In basic terms.

If people don't understand a process it's easy for another person to make a claim that seems valid, basic simple research by asking why something happens will usually find you the real answer.

Then answer the question why when these events you claim happen are ALL on VIDEO my do people with them not see it.
You don't know how video works as stated examples above motion blur, artifacts etc . Try it with any video, movies are shot at 24 frames per second if something is moving fast you will have motion blur on a frame it actually adds to the realisim when you watch it.
Go to Google images do a search for motion blur in movies you will see hundreds of examples, then read some articles on why motion blur happens and why it actually makes things more realistic.
Look Captain Jack is a reptilian

What is this fascination some people seem to have with lizard people or reptile people. All that you posted has nothing to do with what is real. But what is perceived as real, to perceive something as real is just as good as real but not quite real.
Its just mental games, if you like all that, just watch politics, though its less entertaining.

it has been pointed out to you many times now how and why you are wrong but you still keep up this nonsense. Either there is something wrong with you or you are trolling, or both.

Here come the retarded compression arguments again from all the virgins.
Anime retard? You want a time location again?
