Summary | 0000509: Major Frame Drop with 60fps video on 4K TV | ||||
Description | Whenever I open a 720p 60fps video (dont have any 1080p60fps videos to try) on my 4K TV (Samsung UN55KS8500 55" 4K) I get massive frame drop. I do not have this problem on my Acer Predator X34 (1440p). Both these displays are connected to the same computer. | ||||
Steps To Reproduce | open a 720p 60fps video on the 4k TV. | ||||

60fps requires 2.5x as much GPU power as 24fps, so there is a good chance your GPU simply can't keep up with the workload, with your current madVR settings. Can you attach a screenshot of the Ctrl-J OSD in the situation where you get the frame drops? Then I can probably say more. |
|
It occurs only at its normal scaling too though. Before I enlarge the window at all. Will upload shortly |

There are a lot of dropped and repeated frames with any image upscaling other then DXVA2 in fullscreen with this test file (I belive there is no problem with copyrights for test purpose): ffmpeg -i https://vod.edgecast.hls.ttvnw.net/2b26ddc8654d69c4a2e8_quakechampions_26489841168_724285264/chunked/highlight-182711054.m3u8 -ss 00:00:00.00 -t 00:08:00.00 -c copy qc_dhw.mp4 MediaInfo (MPC-HC internal) Format : MPEG-4 Format profile : Base Media Codec ID : isom (isom/iso2/avc1/mp41) File size : 305 MiB Duration : 8 min 0 s Overall bit rate mode : Constant Overall bit rate : 5 326 kb/s Writing application : Lavf57.71.100 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L4.2 Format settings, CABAC : Yes Format settings, RefFrames : 3 frames Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 7 min 58 s Bit rate mode : Constant Bit rate : 5 200 kb/s Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 59.940 (60000/1001) FPS Minimum frame rate : 58.824 FPS Maximum frame rate : 62.500 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.094 Software: madVR: 0.92.7 MPC-HC 1.7.13.112 (f6124a334) LAV Filters (internal): 0.70.2.66 Radeon Software Version: 17.5.2 Hardware: LG UHD monitor Graphics Chipset: AMD Radeon (TM) R7 360 Series |

Update: no frame drops with Bilinear, Cubic upscaling. Seems, H/W (CPU, GPU) power related problem. OSD stats, madvr configuration in the attached files. No difference between DXVA2 (copy-back) and DXVA (native) settings in the LAV Video Decoder. Windows 7 SP1 x64 |

I'd suggest to use a cheap(ish) "chroma upscaling" algorithm, maybe even Bilinear if that allows you to choose a better image upscaling/downscaling algorithm. For image downscaling I'd suggest SSIM1D100, if your GPU can do that without dropping frames. For image upscaling I'd suggest NGU Sharp or Standard (for good quality sources) or NGU Anti-Alias (for bad quality sources). Probably your GPU will struggle, though. So try NGU "low" quality. If your GPU can't handle that, try Jinc instead. If that's also too much, I'd suggest Bicubic75. |
