![]() ![]() (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). ![]()
