Right now the Amazon Prime bitrate options will say things like 15000 kbps when in actuality it's closer to 3000 sometimes and possibly even worse than that. In the example of Avengers: Endgame. it's about 3200 kbps at 1080p CVBR at the highest quality downloaded. After reviewing some scenes actually look better on the 720p version from Disney which download at about 3600 kpbs at 720p (I assume also CVBR by default) due to extreme pixelation in the Amazon version due to the over compression.
Based on the number of pixels I would expect similar quality in the 1080p version to be significantly higher than 720p as there's more than 2x as many pixels. I know that it is not linear when compression is involved... but I wouldn't expect it to be less in ANY case for similar compression quality.
Rather than always saying 15000/8000/etc, can we get meaningful, realistic bitrate numbers before we waste time downloading crappy sources?
