Those are the two options for using your GPU for the encoding versus using your CPU.

In the middle of the screen, you’ll see a drop-down menu labeled “Video Encoder.” Click on that drop-down menu and you should see two NVENC options: H.264 (NVenc) and H.265 (NVenc). To change from CPU encoding to GPU encoding, click on the Video tab: My mouse is on Super HQ 480p 30 in the image, but I selected Super HQ 1080p. For this tutorial, I’m just going to use a General Preset, but I want to illustrate the difference in encoding speed, so I’m going to select Super HQ 1080p30 Surround rather than Fast 1080p30. Once it’s done, you’ll need to select what format you want to convert it to. HandBrake will run through the file, gathering information about the codec, subtitles, audio tracks, etc. Open up HandBrake and load your file you want to convert by clicking on “Open Source.” Find the file you want to convert and select “Open.” I’m going to convert that to a 1080p H265 video file that is substantially smaller in size. I used MakeMKV to pull the video off the BluRay disc, resulting in a 31.7GB file. I’m making a backup copy of the video to store on my file server. The video I’m using to illustrate how to use GPU encoding is a Blu-Ray rip of Pan’s Labyrinth. My GPU (GeForce GTX 1060) and my driver version: 440.100. My CPU is an AMD Ry6-Core, 12-Thread processor. I’m using a GTX 1060 and have Driver version 440.100 installed. Also, to use Nvenc encoding, you’ll need the Nvidia Graphics Driver 418.81 or later and an Nvidia GeForce GTX 1050+ series GPU or better per HandBrake’s documentation. How to Use NVENC GPU Encodingįirst, make sure you have the latest version of Handbrake installed (as of that is version 1.3.3). Version of HandBrake available from the PPA that has NVENC/GPU encoding capabilities. HandBrake 1.3.1 is the current option in the Ubuntu 20.04 repositories. In this post, I’ll show how to use this feature in Handbrake and show some comparisons to illustrate the benefits and tradeoffs that result. Regardless, this option offers dramatic speed improvements, particularly when working with 4K videos. Upload the converted mp4 file to OpenLearning.I don’t know exactly when HandBrake added the capability of using the GPU for encoding, but it was somewhere between 1.3.1 (current version in the Ubuntu repositories) and 1.3.3 ( current version on PPA). Press the “Start” button to begin the conversion. (Select the “Browse” button to choose a different location to save the converted video file.) In the “Save As” field, the type file name for the converted video file. Open Handbrake, and immediately you would be prompted to choose the video to convert (otherwise select the “Open Source” button on the toolbar).Ĭhoose the “General > Fast 720p30” as the preset. Using a desktop application (such as the free tool “Handbrake”) to convert the video. This can be done by:Įxporting the video from your video editing software in the appropriate format, or To avoid slow uploads and transcoding delays, video files can be prepared in the recommended format prior to upload. However, this may involve a slow upload of an unnecessarily large file (if your video is unoptimised) and the video will not be made available immediately, as further processing (transcoding) is required after the file upload has been completed. In some parts of the platform where learners are prompted to share video files, the learner can still choose to continue the upload by selecting 'Convert my video'. The video has a maximum resolution of 1280 pixels in width and 720 pixels in heightĪ video file meeting these criteria will be uploaded to OpenLearning as quickly as possible without incurring any further processing delay. The AAC/mp4a codec is used for audio compression The H.264/AVC codec is used for video compression It is recommended that video files fit the following criteria prior to upload: Video files uploaded to OpenLearning are checked to ensure that the video and audio are encoded in a way that is suitable to be delivered over the internet.
