Recently, a video by Adam Mosseri went viral on Threads that stated, the quality of the video shared on Instagram depends on its level of popularity. This caused many users to feel angry.
"We bias to higher quality (more CPU intensive encoding and more expensive storage for bigger files) for creators who drive more views,". "It's not a binary [threshold], but rather a sliding scale." – Adam Mosseri
Adam Mosseri explains that Meta favors high-quality video for more CPU-intensive encoding and more expensive storage for larger files. Therefore it makes sense to focus on content creators with the highest number of views. It is also not a fixed thing but more of a changing scale.
In addition, he also added that the change in video quality will not affect the reach of the creator's content. It also only affects the average user watching the video, not the video creator's account. Mosseri also said that people will watch videos more because of the content than because of the resolution. For those who don't know, Meta explained this last year about how videos on their platform are processed.
