  • best file quality to download

on alot of the scenes i already have downloaded they have an h.264 original file thats like 20 or 30 gigs then there is a newer h.265 file thats much much smaller in size...my question is this...which file is overall better quality...the newer h.265 smaller file size one or the older h.264 original massive file size one...can some one please help me with this question

Quite frankly, between an x265 version from here and x264 from the official publisher, I can't really tell you which version is the best.
Usually, to see the differences in quality on files of these two codecs, I run the two files, pause and stand at exactly the same frame to see the differences (and switch from one video to another).

Unfortunately, for VR videos, it's more simple because we cannot launch two videos at the same time and even if we had two headsets, switching from one headset to another, we necessarily lose the feeling of the videos ( unless there really is a huge difference of course).

Technically, a x265 video can easily be 2 times less heavy than a x264 video and if you push the encoding options fully, you can even reach 3/3.5 times more.

I'm not sure that SLR fully optimizes the compression options, but I have no doubts about the quality of their video compared to the original videos for a much less weight.

Personally, all the videos I had before in x264 and which are available on SLR, I recovered them in x265 and with a higher resolution (as I have a vr gear, I took files in 1440p or 1600p, now , I recover them in 1920p) for a weight that is either equivalent or less (I saved a loan of 5TB thanks to the x265 videos).

And unfortunately, as SLR does not do all the studios yet, the rest, I re-encode them myself (for example, I recovered all the badoinkvr and naughtyamericavr at minimum in 1920p and I re-encode all that, even if it takes a long time , especially since I don't have a very powerful cpu (I7 6700HQ)). But little by little, I see the saving of space that I am doing for a higher quality than what I had before.

    midorijin wow your answer helps me out so much...i have so many videos that i have multiple copies of the original and the h.265 version so now im just gonna go back and delete the original files cuz they take up waaaaaay too much space...i had a 10 TB harddrive specifically just for VR porn and its already almost full due to all these massive original file sizes i keep downloading...im just gonna start getting the h.265 versions over all the older h.264 originals...thanks so much for your input

      I guess it's a bit late to mention this now, but the originals are always better quality. (Non-lossless) re-encoding always loses quality, no matter how you do it. And in a few comparisons I made from SLR's material, the difference was bigger than I thought it would be. That said, if you don't see a difference, maybe you shouldn't bother.

      Not to nitpick, but all our HEVC files are h265 compliant.
      AVC files up to 4K are h264. AVC larger than 4K are x264

      The Original files depend on what the studio themselves uploaded.

          Rakly3 Abuse of language on my part to use X instead of H (just like abuse of language to use 4k instead of UHD).

              Rakly3 H.264 is a standard. x264 is a specific video encoder that encodes H.264 video.

                  gurphh yes, h.265 can be decoded on hardware, x265 can't. ie AVC@L6.x
                  I'm talking about decoding of our video formats on SLR. The x265 encoder can encode in h265 compatible format, true.

                      midorijin Well, for VR there are no formats that fit, they mostly 2:1 ratio.
                      The only thing that is universal no matter what studio or equipment, is which decoding capabilities you need for playback of the file.

                      1920p or 2160p, both need minimum 4K decoding.

                        Rakly3 I don't know what AVC@L6.x is, but x264 and x265 are not formats, they are encoders. And video that x265 produces can be decoded on hardware, depending on the encoding options you use.

                        Edit: I guess L6.x was short for Level 6.x...

                            gurphh Yea, x265 can encode h265, but not all HEVC or AVC can be decoded on hardware, thus only on software, x265 decoder. I'm talking about our videos and if or not they can be Decoded on hardware or need x265 decoder.

                            Our HEVC videos are h265 compliant.
                            Not all our AVC videos are h264 compliant.

                            I don't think we are actually disagreeing with eachother.
