Discuss : Nvidia Hardware Accelerated Encode for H264/HEVC

With the latest Adobe Media Encoder Beta build we have enabled Hardware Accelerated Encoding through Nvidia GPU card.


If you have Nvidia GPU card on your Windows machine, you will be able to use this feature.


To enable this option, select H.264/HEVC from the Format drop-down under Export Settings. Then under the Video tab, go to Encoding Settings and set the Performance to Hardware Encoding. Setting it to Software Encoding will disable hardware encoding and Adobe Premiere Pro won't use Nvidia HW to encode the media. Please see attached screenshot.

Feature is enabled in Adobe Premiere Pro Beta , Adobe Media Encoder Beta and Adobe Premiere Rush.

 

Please try out the feature and share your feedback.

    I'm unable to select Hardware Encoding, although I can use Mercury HW in Premiere itself.

    Message "Your system doesn't support hardware encoding in the current settings."

    Could you allow 10bit HEVC encoding in future patch? Banding will greatly reduce from 8bits to 10bits. Thanks, awesome work guys!

    Hi,

    I'm encoding DNxHD 185x file to Youtube using the default Youtube 1080p preset + changing "Render at Maximum Depth" and "Use Maximum Render Quality" to on.

    The resulting file is 141MB. If I encode with the same settings in the latest AME 2020 release version the resulting file is 1,65Gb. Also if I change in beta AME to VBR 2 pass I get that 1,65Gb file.

    So... this is something that needs to be seen. The default is nowhere near the quality it should be.

     

    Steps to reproduce:

    1. ... Encode DNxHD 185x file with Youtube 1080p preset. The target bitrate is then set to 16Mbps, so unchanged from the default settings.

     

    Result: ... The resulting file is way too small, 1 289kb/s (Copy/Paste from MediaInfo):

    Ah, the plot thickens...

    If I use Hardware Encoding I'm stuck with VBR 1Pass. If I change it to VBR 2Pass AME changes to Software Encoding.

    BUT both give an estimation of 1877MB for the encoded file. Obviously that is totally incorrect for Hardware/VBR 1Pass.

    I tested this with the maximum setting of 62,5Mbps (Hardware, VBR 1 Pass). The resulting file was again the same 141MB.

    This is obviously a very serious bug.
