Obs quicksync settings1/8/2023 ![]() (Image is Webp and need a supported browser) It's very obvious around text, which shouldn't be apparent at all with high bitrates, but i guess it's the fast preset to blame for it? And if it's more than the CPU Usage, than it's not any good, as i can't increase the size too much.Įncoding settings : cabac=1 / ref=1 / deblock=1:0:0 / analyse=0x3:0x3 / me=dia / subme=1 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=0 / threads=6 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=1 / b_bias=0 / direct=1 / weightb=1 / open_gop=0 / weightp=1 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=0 / rc=crf / mbtree=0 / crf=16.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / vbv_maxrate=50000 / vbv_bufsize=50000 / crf_max=0.0 / nal_hrd=none / filler=0 / ip_ratio=1.40 / pb_ratio=1.30 / aq=1:1.00īut still artifacts appear, and they aren't that illusive. How much impact does it have on both?Ĭause if it's off at UltraFast i guess it must have quite in impact on encoding efficiency. ![]() It's disabled in ultrafast preset and in baseline profile. You can disable cabac for lower CPU usage even though file size will increase a bit. The higher the bitrate the longer it takes in cabac encoding. I am Not using VFW, it's done with MP4 so i don't have to worry about B-Frames and such.Īnd, i also didn't know that QuickSync was that worse than Nvidia, which is a bit bad for me as i will likely buy AMD next tiem as well thanks to Mantle, and i don't think AMD's encoder is any better than QuickSync, hope i am wrong though. I think it's thou to the SuperFast preset however, as anything around 16 crf should be very transparent. I actually see quite the difference around Text, pretty much like Jpeg, artifacts. I use crf=18 for offline reencoding of game captured video (frapsed actually) and don't see difference apart from chroma subsampling. I don't think crf=12 is really needed though. Second, i got an i5 760 this doesn't have Quick Sync, so i am really of to no good on any offloading encoding. Now i don't really know what more to say, so better to hear from those who know what can be made with this.įirst off, i don't have a GPU that can encode, i got AMD 6970, sadly one generation below the one that started using it. This gives the quality i want, but it seems it takes a huge CPU Usage. My current settings are with SuperFast preset and CRF=12. Luckily i don't have to bother about bitrate to much, i can afford to use up to about 80mbps (50mbps is preferred though), so this should help get rid of compression efficiency. So in my particular case, i want to record as transparent as possible with at least CPU usage as possible. This however may be wrong, it may be an old understanding, as i haven't bothered using it, but i am not against it if it does what i want. There is however VBR, which i never use as it's known for bad quality, at least in 1-pass cases like these. Now normally, i am all in for CRF, it's the easiest quality control i know, and it's completely adaptive to scenarios. I am wondering what settings are suggested for high quality x264 encodings that can be done in Realtime (at 1920x1200 30fps).
