![]() If software is the only way you see going forwards (though I'd strongly recommend evaluating VTB yourself for a mass conversion), try the nightly build of Handbrake. Difficult to ignore the time savings but presently I'm only using software encodes, it's quick enough on the Ultra with that and the collection has been completed (though I may revisit bits and re-do with software, time allowing) The Ultra will convert over 600fps using VTB (though it needs 2 simultaneous encodes, one on its own is around 310fps). think I might have narrowed it down to CQ37 or CQ38. The M1 Pro/Max/Ultra H.265 encode engine also looks like it's been enhanced over the M1's and my Studio Ultra produces smaller files for the same CQ setting as my Mini, so the process of finding an acceptable CQ values starts again. CQ45 now produces files 10-20% larger than with v1.4.2. ![]() Handbrake 1.5.1 skewed the VTB constantly quality settings and they are aren't comparable to 1.4.2. Software seems to be the only option for them. Note: don't use VTB for cartoons, my settings generally make the output larger than the H.264 source. Yes, the VTB encodes were larger than the software, but are still less than half the size of the originals and in the few months it took to convert my collection using VTB (and reduced disk space usage by 55%) the software encodes would still be going on and in a few years would have saved a few more TBs but by the time the VTB encoding was completed, would have saved very little space ('cause very few files would have been converted) Software producing files that were 25%-33% of the original H.264, VTB 33% to 50% of the original. Software encoding was yielding 15-25fps, VTB 180-220fps. Both may be more than I could get away with, but the aim of the conversion project was to "save disk space", not "save as much disk space as I possibly could" and I wanted to be sure that the output wasn't going to disappoint me. I've attached my two presets (not so much to share them, more it's easier than listing what settings they contain), but with Handbrake 1.4.2 on the M1 Mini (it was current when I started my project), I found software RF20 to be more than acceptable and also VTB CQ45. ![]() Also potentially not helped by hardware or software changes. I eventually settled on H.265 10-bit as my preferred encoder but then the challenge of finding "the best" quality/speed compromise begins. are purely CPU-intensive tasks.īut take into account that CPU encoding is always better in quality and smaller in size.As Box mentioned, finding settings in amongst the myriad of options Handbrake offers and then trying to decide which one provides the smallest file sizes and best quality viewing experience is hard, to say the least If your Mac or PC comes with no compatible hardware, the video decoding, encoding, metadata processing, remuxing, commercial removal, etc. ![]() However, your computer must have the supported hardware. GPU hardware encoding is especially important for H.265 encoding. Thus there will be no Handbrake high CPU usage, overheating, or system crashes. If you select a profile that is using hardware encoding with a supported hardware encoder, the video conversion will be handled by the GPU and the CPU will be released. Then Handbrake video encoding will be given less CPU when there are other tasks in progress.Ĭhange HandBrake CPU Priority 3. Open the dropdown menu and set the Priority Level to Below Normal or Low.Go to the Advanced tab under the Preference Tools window and find the Priority Level.Open Handbrake and click the Preferences and choose Tools.
