I'm also fairly clueless about the process. Launching or exiting full screen 3D applications or games often causes temporary blinking even on secondary monitors. Can such simultaneous uses of the video card affect the encoding results? Or is the process entirely self-contained and checks should only be run on more serious cases like driver crashes?
Other than that concern, the difference in speed is pretty amazing with my setup. With the GPU boost, HEVC encoding finally takes reasonable amounts of time. Great new feature. |

Hardware video decoding is performed on dedicated ASIC not on some shader units in GPU.

I have a 60fps gaming sequence ... how can I Change/Decimate/Blend/ConvertFPS() downto 24fps.
The Decimate option in RipBot264 is greyed out. I've never toyed with avisynth but I'm keen to experiment. Also, how do I encode in CRF (constant rate factor), rather than CQ (constant quality). It's my first time with RipBot ... previously with HDConvertToX and then Xvid4psp (which recently became donation-ware). I love the app, esp the option to encode with GPU support (currently running on a dual core with Nvidia 710). Thanks much |

Is there an option for AAC-He v2 VBR ... The VBR is useful in avoiding wasted bits during quiet moments and v2 uses 1 channel to replicate the stereo differences. All in all, even at maximum quality the bitrate hovers around 48 kb/s (suitable for most PC or built-in TV type speaker systems). Is it true that h264 encodes are more efficient with "width MOD 32 = 0" and "height MOD 32 = 0" ... ie width and height perfectly divisible by 32 ? Thanks much |

Do not worry about MOD 32 thing. It is just a placebo.
Regarding audio bitrate. Fraunhoffer encoder does not support VBR. Just old good Average Bit-Rate mode. Besides You won't save huge amounts of space by going down to ~48kbps. example 120 min movie 7200s * 8KiB (64kbps) = ~56 MiB 7200s * 6KiB (48kbps) = ~42 MiB So with 2h movie you save just 14 MiB. That's nothing these days.

that fighting over a few kb/s is really "penny wise and pound foolish". Even the DL or storage of complete bluray ISO images (30+ GB) is getting more popular and 10 TB HDD's (see Storinator link) are also becoming more affordable Quote:
but CQ bunched all the quality around one quantizer (as seen by AVInaptic, for eg). At least CRF compensates for human eyesight by attributing bitrate according to perceived experience (a bit like what VBR does for audio). I've been trying to encode a Pavarotti concert compilation, released on NTSC DVD (Duets - 2008) interlaced BFF. How do I deinterlace ... and reverse telecine the 29fps downto 24. Each time it's halved the video time ... from 1hr 10 min downto 35 min. The Decimate window is active but Deinterlace is greyed out. I'll try the Decimate -> 23fps only.

You either decimate Telecine (originally progressive video with duplicated fields, removing the duplicates to restore the original progressive content), or you deinterlace regular interlacing (it was never progressive, the recording time advances from field to field). They are mutually exclusive. And Telecine only exists in the NTSC world.
Perverse norm conversion results are not mentioned here. Reconstructing those is a higher skill. |

It always looks like it's frozen but after 10-15 mins you should be able to continue. Has been this way since 1.24.1 |

Audio is fine but video runs for 35 min (23.976 fps) instead of 1hr 10min. Job Log Quote:

You should upload sample of original source file...
Ps. I suspect that problem is related with variable FPS in original video.
