Hello just making a poll, which one do you prefer? personally I prefer x265 but since the rarbg falldown i've seen that almost all 1080p rips are in x264, what do you think about that, and do you recommend any place to find more x265 content beside those in the megathread?
Ah yes, you see these are number terms that indicate how videos are encoded. I absolutely understand how to feel with this post and are worthy of participating in the smart discussion in the comments.
imposter syndrome aside, left is a nice grid, right is a really really bad attempt at drawing a golden ratio. Sure left is better to maintain average quality. Why are people talking about converting to one and then the other? Why is the golden ratio one not symmetric!
I know this is a joke but if anyone is curious, the grids indicate how the compression works with each format.
Im far from an expert, but what I've picked up over the years is that videos are compressed by analyzing changes from one frame to the next. If two frames display the same colors in the same grid, the algorithm will recognize this and eliminate the duplicate information (i.e. this 10x10 pixel square is all red for the next 10 frames so record this grid square as red once and use that recorded value 10 times) and only storing what's changed from one frame to the next. With x264 the grid sizes are fixed so some duplication occurs and you have to store information for every grid. With x265, the grid size can scale as needed so you can store more information in a single 'container' (i.e. this 100x100 pixel square is all red for the next 10 frames) allowing compression to be more dynamic when it needs to be leaving you with smaller file sizes.
The joke was precisely that i was to dumb to properly understand this post. Thank you very much for your explanation. I definitely see the benefits x265 can have now. And i may actually use that knowledge when i see download files for both codecs.
I take it the images in the post aren’t the greatest reference then as one of the squares contains both background a portion of a face.
Makes me wonder what ai will allow us to do in the future knowing exactly what information can be compressed and what focus points must remain highest quality.
