![]() On other tests.ĬPU usage is now 90-100%, a 1080p H265 encode as used in the thread before this one would be at ~40-50% CPU usage. It's used for streaming games as well as applications like. Intel quick sync is a hardware accelrator for h264. It keeps file video smaller without losing too much quality. For those who dont know Handbrake is a encoding software that i use to get h264 encoding. Without these tweaks (relaxed EDC and performance bias) sure, you can clock higher at the same voltage but then you end up at about the same final performance in this test so I leave them on. Decided to try out the hardware I have and see which quick sync is the best. Video decoding (if QSV decode is disabled or your source is in a format which is not supported by the QSV hardware) 2. and that was at ~80☌ on this and ~18☌ ambient temperature. HandBrake supports both QSV encode and decode. Man, that voltage wall is more present than ever on this very early R7 1700, batch 1708ģ975-4025MHz would crash at 1.45v + LLC4 set in BIOS, had to back down to 3950MHz with all the performance enhancing options on to finish the encode. ![]() Linux and Mac platforms are excluded from this tech. Handbrake Intel QSV hardware acceleration is only available for Windows. There are several encoding presets for x264 in Handbrake: Ultra Fast, Super Fast, Very Fast, Faster, Fast, Medium, Slow, Slower, Very Slow, Placebo. Open Handbrake click 'Preferences' under Tools click 'Video' and make sure that the option 'Disable QuickSync Decoding' is not selected. In a recent video I showed how to enable GPU/hardware encoding in Handbrake and demonstrated how much it speeds up encoding times over traditional software e. Daily settingsĮncoded 1806 frames in 416.04s (4.34 fps), 11820.04 kb/s, Avg QP:29.09 Im pretty sure using one thread in Handbrake when youve got a multi-core CPU is not what that phrase is referring to. Encoded 1806 frames in 430.69s (4.19 fps), 11820.04 kb/s, Avg QP:29.09 Intel® Quick Sync Video uses the dedicated media processing capabilities of Intel® Graphics Technology to decode and encode fast, enabling the processor to complete other tasks and improving system responsiveness.
