    If camera HEVC stream matches standard 4K HEVC native files (both 8 and 10bit) must be editable in properly made NLE on latest GTX cards or even CPU.

    Yet most popular NLEs internal pipeline design is very old and so horrible...

  • RX480 and Vegas 14 working fine here.

  • @fatpig

    It is not about HEVC decoding in general, it is about GPU support.

    As far as I know, if HEVC is decoded by hardwire in Vegas it is only if you have suitable CPU (QuickSync).

  • does quicksync only work with igpu? or if I put in an nvidia 1080ti (or any other nvidia gpu) do I lose these cpu decoding features?

    Also, what does that mean with i9? will i9 that has no igpu has some sort of decoding features? or "quicksync"

    really i mainly care about premiere and media composer usage. I think there are 2 things to think about in this topic... Render speeds, and playback speeds. Obviously ryzen renders pretty quickly, but playback uses different tech no?

  • does quicksync only work with igpu? or if I put in an nvidia 1080ti (or any other nvidia gpu) do I lose these cpu decoding features?

    QuickSync is part of Intel GPU. If it works while 1080ti will be making output depends on NLE and settings.

    Also, what does that mean with i9? will i9 that has no igpu has some sort of decoding features? or "quicksync"

    i9 is actually remarked Xeon line CPUs without GPu at all, so no QuickSync.

  • thanks... and whats your opinion on these new i7 cpus? 7740x 7800x 7820x

  • @cls105

    They are kind of useless, whole lineup is temporary patch until 6-8 core consumer CPUs.

  • With Apples use of HEIF on iOS 11 we will most probably get system wide HEVC support sometime soon in macOS... I'm sure MS will update as well.

  • @alcomposer

    They already included system wide HEVC support in High Sierra, if you missed it.

  • I missed it. Only had my android device which "does not support live streaming" lol

    Ironically "live streaming" works on MS.

  • I missed it. Only had my android device which "does not support live streaming" lol

    Guys who made such streaming are idiots, as such decision cost them tens of billions of dollars.

  • NVIDIA Video Codec SDK 8.0 release. Highlights of the release include:

    • 10/12-bit decoding support with HEVC/VP9, enabling end-to-end HDR transcoding Improved quality via weighted prediction
