re encode? not familiar with the term
Short story: all videos ever dropped here come in MP4, MOV, WMV, MPG, TS, AVI or FLV format. They use older codecs (primarily x264 or AVC). A new codec (HEVC or x265) allows for significant compression of such videos without significant loss of quality. The best determiner of the quality of a video isn't the resolution (so 1080p, 4K, etc.) but the BITRATE of that video. A 1080p video at 4000kbps may look better on screen than a 4K video at 1000kbps. That's why your Netflix 4K series will sometimes look like shit: Netflix throttled the bitrate they're offering.
Now, for porn, it is my opinion that you don't need crazy high bitrates. The best videos for re-encoding (x264 -> x265, with the MKV container) are those with high bitrates to start (guys like
@Jang-A-Lang - Jang-A-Lang ,
@Where dem killas hang ... drop these most frequently. Salute to them). Such videos can have a bitrate of 14000kbps or more. That's why a 1-minute video can be 100MB in size. Nobody's out here watching porn on their 4K TV, so whatever quality is lost (minimal with the right settings) won't be noticed at all. That same 1-minute video will now have a much lower bitrate (depends from video to video), meaning a smaller file size. Using c0zy+h0+ as an example, her MEGA was around 30GB in total. After re-encoding all her videos, the folder is now roughly 3.3GB. That's significant. The person who made that MEGA had the OG rip. Negligible difference in quality, much more space saved, more hoes stored.
You use programs on a PC to do this (I use Handbrake). It eats up the CPU though, so if your PC ain't shit, don't try it. Ideally, all the videos in a MEGA would have the same resolution, since I could just apply settings once for all videos, but with these drops, you'll have 480p, 720p & 1080p in the same folder, and some videos need the black bars cropped out (Handbrake identifies this automatically, but it changes the dimensions of the new video). Thus, until I figure out a script for doing it automatically, I have to look at each video individually and determine the best settings. After all that, it runs until all the files in the queue are done. I do one thot each run. After that, I delete the originals, then replace them with the new videos.
I'm running unic0rnr!ah's shit right now. Almost 50GB for the original files. I could be looking at about 15-25GB once it's done.
Apologies for the long post, man.
