    HEVC Hardware Accelerated encoding no longer works in Monterey

    I recently upgraded my 2020 iMac and it no longer allows me to encode to HEVC using Hardware Acceleration (Video Toolbox). I've tried this using ffWorks and a program called VideoProc. I've been using this functionality for 18 months now, and after upgrading the Monterey, it stopped working. Is...

    MP 7,1 W5700X: HEVC/H.265 10-bit Performance / Canon EOS-R5

    Interesting video: The video shows Mac Pro 7.1 w/ Vega II getting trounced by an iPad while scrubbing the HQ Canon footage. Anybody out there with W5700X and just released EOS-R5? I'm curious to know if W5700X makes a difference. In theory, I believe it should since based on the newer NAVI...

    MP 1,1-5,1 Mac Pro 5.1, Vega/VII and Resolve + Catalina – please read

    I'd appreciate if anyone with a a 5.1 and at least Vega graphics that has updated to Catalina and runs DaVinci Resolve could check if they get HW accelerated 10bit HEVC encoding. You will need the latest Resolve 16.2.2 to check. Export to h.265 Main10 and report back with fps during export (on...

    T2 chip-accelerated HEVC conversion with Handbrake

    I read here that I just need to specify -c:v hevc_videotoolbox for an ffmpeg GUI like Handbrake to convert to 8bit H265 using the T2 chip for hardware encoding. I tried specifying --encoder hevc_videotoolbox in the Additional Options section of the video tab in Handbrake. It really didn't seem...

    HEVC Hardware Acceleration - GPU Support

    Can anyone confirm if OS X will detect and enable h265 hardware acceleration in Polaris GPUs in a 5,1 mac pro? The cards support it but wasn't sure if OS X will leverage the card or if it is only for Kabby Lake CPUs. Thanks!

    VLC 3.0.1 - HEVC 4k x265

    I just installed new VLC 3.0.1 on 2017 15" Macbook Pro and it is running all my 4k HEVC content flawlessly with very low CPU usage. Looks like they have finally added hardware decoding. Results are much better than IINA. I also have a 2016 13" Macbook Pro Touchbar (2.9Ghz i5) and it didn't make...

    Best conversion of 1080i50 to 1080p50 HEVC?

    I have a good but older video camera that records at 1080i50. It imports fine into Photos (or iMovie), but the files are very large, PLUS Apple blends the 2 interlaced fields so there's a constant blur to the image. I keep all my Photos and videos in iCloud. Can anyone recommend a good app on...

    Conversion required when airdropping pics/vids in iOS 11 to other iOS 11 devices?

    Aidropping photos and videos takes an eternity for me now. Last night I sent 3 short videos I had taken on my iPhone X. The videos were HEVC, 4K 60fps, and about 10 seconds long each. When I sent them, it took 8 minutes to go through “converting” them. In the early days of iOS 11, converting...

    iPhone iOS 11 video mode reset to 1080p at every lunch

    Hello everybody, I searched for this bug everywhere, and it looks like I am the only one with it, or maybe no one wants to talk about it. I had an iPhone 7 Plus, now I have an iPhone X. On my iPhone 7 Plus, my video setting was 4K at 30 fps. Now on the iPhone X, I choose 4K at 60 fps. BUT…...

    Manually Convert to HEVC?

    I have found I am able to export HD videos I open in quicktime to HEVC. This option is not available on SD videos and the like. Is there a manual way to convert any video to HEVC? As far as I can tell the command line avconvert program does not support HEVC.

    HEVC Goodness - Hardware Acceleration in High Sierra

    IINA got updated with the latest ffmpeg that supports hardware acceleration 2 days ago. These numbers focus on the difference between hardware accelerated and non-hardware accelerated decoding of HEVC 4K UHD content. IINA is as of now my favourite media player but I have to mention something...

    What Happened To Hardware Acceleration in High Sierra?

    I read in some threads that VLC already supports hardware decode. Even a VLC developer said this. To me and to my specific usage, VLC is pure horses**t. It's the worst player being intensive resource hog that doesn't seem to think about battery at all. I found IINA and have been using it since...

    HEIF/HEVC, iCloud Photo Library, and older devices?

    Say I take a photo on my iPhone 7 in high efficiency format, and then it uploads to iCloud Photo Library… will I be able to view it on my other devices that don't support iOS 11/macOS High Sierra? I'm assuming it'll generate a JPEG preview, but I won't actually be able to view the original file?

    iOS11 and corrupt HEVC-files?

    I can usually playback HEVC-files on my computer but when I try to open those from an iPhone device it's just a big mess of graphics. Another video-editing program I've got says the HEVC-file has corrupt frames. Is this a known issue in iOS11?
