  • Which download option for best visual quality

I'm a new member and curious which download option is best for visual quality for my odyssey? It looks like for most videos the original version is larger in terms of file size.

Should I be downloading the original or the smaller version?

Are the smaller files re-encoded versions done by the SLR team? Has any visual quality been lost in the process?

Thanks!

    This is a really broad topic with a lot of "ifs" and "but's"
    Short answer. The large original file is the studio file. They also provide smaller 'original' files. It's easy to recognize them because they have the word original in the file-name. (Other than SLR Original)

    The others are transcoded for the purpose to be compatible with the device they are listed under. Not every device can play the same coding settings.

    In theory there always is loss of quality during compression, so also during re-coding. In practice, visually this isn't necessarily the case as much still depends on your hardware and display too.
    In cases of increasing the framerate the experience might even increase.

    As for which quality for your odyssey. (Numbers are approximates, I'm using 110° vFOV => 100° hFOV)
    ((1440/100)x180)x2 = 5184px
    So 5K should be a good fit for you.
    Ofcourse, 4800px is also called 5K, so take it with a grain of salt. If your PC can handle it, go for 6K
    Also 6K for fisheye. (200°+)

    My PC is capable of running 8K, I have a Reverb G2 on preorder and my main concern is getting the best visual quality. I have been downloading the files for windows mr but there is always 2 options there and I'm unsure which is best. In this screenshot I have circled the two options I am unsure about.

    Should I be downloading the "original" 26.67GB file or the 8.08GB option? What is the difference? I'm assuming the 8GB file is heavily compressed and there must be loss of visual quality?

    Thanks!

    I have noticed that some studios are doing 7 and 8K with bitrates in the 40-60K range. And other studios are doing 5 and 6K videos with bitrates in the range of 80-120K and these file sizes seem to be getting a little out of control. Am I wrong in assuming that some studios might be trying to compensate for a lower quality camera rig by cranking up bitrates?

    The following specs are from a recently released scene from sexbabesvr -
    Duration:00:38:15
    Format: MP4
    Size:3,29 GB
    Video:MPEG4 Video (H264) 4320x2160 59,94fps 12338kbps
    Audio:AAC 48000Hz stereo 383kbps

    Duration:00:38:15
    Format: MP4
    Size:33,5 GB
    Video:MPEG4 Video (H265) 5400x2700 59,94fps 125456kbps
    Audio:AAC 48000Hz stereo 317kbps

    Going from 4K to 5K there is a 10X increase in kbps and total file size. WTF???

      erniescar69 actually far from it.
      High resolution with less bitrate lowers the quality.
      I'd rather even pose they are cranking up the K's for marketing.

      a 5K-6K video with higher bitrate in many cases will look better (assuming the sourcefile is any good)
      It also greatly depends on the codec. h.265 can on avg almost half the bitrate of h.264 but keep the same vidual quality.
      Again, with a lot of 'ifs' and 'buts'

      That h.265 one you posted I'm pretty sure is the lossless h.265 recording. Editted ofcourse, but not compressed.

        Rakly3 That h.265 one you posted I'm pretty sure is the lossless h.265 recording. Editted ofcourse, but not compressed.

        Ahhh...that makes sense, something I hadn't considered.

        I did try downloading both the 26.67gb and the 8.08gb files to test and I honestly can't really see a difference between them. Is this a limitation of the displays in my odyssey?
        I'm trying to build up a library of HQ videos for my Reverb G2. Should I be downloading the larger files?
        Thanks Rakly3!

          erniescar69 Partially limitation of the display, but also means they did a good job with the coding settings for the targeted headsets.

          Next gen we might even see support for AV1, which would make the files even smaller at same quality. So far only the Nvidia 30x0 support it.

          For the reverb 2 get the best quality you can find (and your system can handle) 🙂
          It's starting to feel weird to always bring up this thread, but it just has a lot of (visual) information in it.

          (I didn't work here at SLR yet when i wrote that, and also was still learning about x265. So I might not have all the details 100% correct back then. But the principal still stands.
          'Higher resolution doesn't equal better quality.'

          Usually bigger file better quality but x.264 or 5 are good codecs so yeah might not notice the difference if it was well compressed.
