Learn about MPEG compression artifacts.
When the eyeballs move rapidly left to right or right to left, the MPEG compression encoding sometimes does not keep up.

MPEG video compression artifacts. The eyes move more rapidly than other parts of the scene and sometimes the compression algorithm does not keep up, displaying pixels that were previously in that location of the frame during a subsequent frame.
It's not film, anon. Digitizing video sometimes introduces faults.

The appearance of blackened eyes on Strzok is creepy, but are you familiar with video compression artifacts?
The MP4 video compression algorithm (or whichever one they are using) is designed to calculate rectangular blocks of pixels on a video, and decide which ones are moving fast versus not moving. It is able to compress the video by ignoring the ones that are not moving much and representing them with a shorter string of bits from a table, and working mainly on the ones that are rapidly moving. The table gets recalculated as necessary when there are major changes in the scene. Changes in the video over time are represented as a delta from a periodic key frame that is transmitted in a fuller format.
A person speaking will have their eyes, lips, face, hands, head, etc. moving quite a bit. Sometimes the compression algorithm cannot keep up and will render a block of pixels in the previous color that was present in that part of the frame. Similar things can happen.
People are accustomed to thinking digital video is the same as film, but it isn't. Understanding how the underlying hardware, software, and networking turns the bits into digits and then transmits them, and then how it gets rendered on your device, is necessary before jumping to unjustified conclusions.
There are many articles on this topic.
A few relevant extracts from https://en.wikipedia.org/wiki/Compression_artifact :
A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression.
Lossy data compression involves discarding some of the media's data so that it becomes simplified enough to be stored within the desired disk space or be transmitted (or streamed) within the bandwidth limitations (known as a data rate or bit rate for media that is streamed). If the compressor could not reproduce enough data in the compressed version to reproduce the original, the result is a diminishing of quality, or introduction of artifacts. Alternatively, the compression algorithm may not be intelligent enough to discriminate between distortions of little subjective importance and those objectionable to the viewer.
compression artifacts occur in many common media such as DVDs, common computer file formats such as JPEG, MP3, or MPEG files, and some alternatives to the compact disc, such as Sony's MiniDisc format. Uncompressed media (such as on Laserdiscs, Audio CDs, and WAV files) or losslessly compressed media (such as FLAC or PNG) do not suffer from compression artifacts.
The minimization of perceivable artifacts is a key goal in implementing a lossy compression algorithm…. …
Video
When motion prediction is used, as in MPEG-1, MPEG-2 or MPEG-4, compression artifacts tend to remain on several generations of decompressed frames, and move with the optic flow of the image, leading to a peculiar effect, part way between a painting effect and "grime" that moves with objects in the scene.
Data errors in the compressed bit-stream, possibly due to transmission errors, can lead to errors similar to large quantization errors, or can disrupt the parsing of the data stream entirely for a short time, leading to "break-up" of the picture. Where gross errors have occurred in the bit-stream, decoders continue to apply updates to the damaged picture for a short interval, creating a "ghost image" effect, until receiving the next independently compressed frame. In MPEG picture coding, these are known as "I-frames", with the 'I' standing for "intra". Until the next I-frame arrives, the decoder can perform error concealment.
