It is noteworthy for including a string of text from the Wikipedia article on "Art". (see below)
Description of video
At 9:43:20, this is one of the longest videos posted by Unfavorable Semicircle. The visuals contain a flickering series of colored frames.
The audio is a mono track with a variety of data transmission type sounds throughout.
There is a sort of structure to the audio, with a series of "spikes" that sound like there are LIMIT-style noises mixed in with the data transmission sounds. It starts with the same log-on/log-off "handshake" noise from the end of ♐ZUFCHO.
The Unknown Voice speaks the letter "B" (or possibly "E") near the start and again a number of times throughout the video (it could be at other places, especially inside the louder spikes, but initial analysis has found the letter repeated at 0:06:58, 1:08:48, 3:21:15, 4:20:06, 4:44:33, 6:13:34, 6:20:32, 6:25:38, 6:33:04 and 6:38:52) — there is no obvious pattern to these repetitions. Immediately after the "loud" section ending at 4:43, the voice counts from 0 to 9.
There is an "interlude" at 6:44:33 (preceded by a handshake/log-off sound) of quieter wump/mic bump type noises that lasts approximately three minutes and forty-five seconds.
There are also several unusual noises throughout the video, including a "calliope"/♐DELOCK type noise at 5:44:33, and data transmission tics at 6:06:45.
Further analysis, especially within the "spikes" will probably reveal further anomalies.
Significance of name
Besides the obvious autumnal resonance of the name, it has been noted that the video was posted on Canadian Thanksgiving.

Significance of Composite
The ♐HARVEST composite contains three "panels" — the top half is clearly related to the ♐DEPTH composite, although the bottom half (and the relationship between the parts) is unknown.
The angled line in the lower right section is similar to the line in ♐RECOVER.
Text in composite
It was discovered by thomasf that the lower area of the top right "panel" contains contains tiny text (black, with green/gray outline around it) which cites the beginning of the Wikipedia page for Art:
closeup of text in ♐HARVEST composite (from thomasf's composite)
same as above, but with corresponding text added for clarity
Art is a diverse range of human activities in creating visual, auditory or performing artifacts – artworks, expressing the author's
screencap of Wikipedia article on "Art" — note the slightly different punctuation than used in the composite
It is possible that this is a straightforward message from the creator(s) of Unfavorable Semicircle that the entire project is meant to be considered as art — or this could merely be found text placed in the image for some other unknown reason — possibly to demonstrate that the project's videos can be used as a means to encode "text" messages.
If is worth noting that although the ♐HARVEST video was posted on October 10th, the version of the text from the Wikipedia article changed from the way it is reproduced in the composite on June 21st.
