The temporal compression is slower than non-temporal one in most case. Of course, its compression ratio depends on source video. Use temporal compression for static video.
That is strange. What application did you use? |

MPC-HC, MCP-BE, Potplayer. I tried ULH4 and UMRG and in each case I only got a black screen with playback not starting. Seeking didn't do anything either, more black and no playback.
(By the way, why the excessive amount of fourCC identifiers? Other codecs that I know of that support multiple color formats of and have multiple compression methods only have one or two, such as AVC.) Last edited by mzso; 23rd March 2019 at 13:58. |

DirectShow is a box of candy; you may have to trace the graph to discover if there is a "filter in the middle" ruining the result. Or it might even be the graphic driver pretending to support a display feature it actually did not implement well. I guess. Don't quote me...

MPC-HC even allows copying the list: Code:
Filters currently loaded: - Default DirectSound Device - madVR - Audio Switcher - UMRG Decoder DMO - LAV Audio Decoder (internal) - LAV Splitter Source Code:

I tried madVR + MPC-HC (x64). This combination makes blank output, as you said.
According to my additional investigation, this is because madVR's behavior is strange and is not compatible with UtVideo's DMO implementation. I am not responsible for it. |

@mzso:
madVR + MPC-HC (x64) + MPC-HC (x32) are doing fine with LAV Filters. I'm using this all the time. Only the UTVideo Decoders give a black hole . And this is how it is for a long time. I don't even remember when this came first to my attention.. But any way: A Big Thank You to Umezawa_Takeshi for maintaining this great Encoder and Decoder ! |

I see interlaced encoding got deprecated in the latest release.
Can we expect that at least decoding will not be dropped subsequently? For VHS archival purposes, I currently use Median Interlaced mode, as it gives ~10% better compression. Also, (and it's _very_ convenient) my player/decoder suite (K-Lite) invokes deinterlacing automatically, that does not happen for the non-interlaced mode (and AVI format doesn't allow to store interlaced flag externally). Compression results for interlaced video (VHS capture, TFF, if it matters): Code:
Gradient 1793 MB 100% Median 1689 MB 94% Left 1669 MB 93% Left Interlaced 1669 MB 93% Gradient Interlaced 1589 MB 89% Median Interlaced 1528 MB 85% Code:
Gradient 1793 MB 100% Gradient Interlaced 1589 MB 89% Median 1689 MB 100% Median Interlaced 1528 MB 90% Left 1669 MB 100% Left Interlaced 1669 MB 100% |

Version 20.4.0 is released
Version 20.4.0 is released.
New features
License (GPLv2) / readme / Windows (exe) / source code / GitHub If you set UTVIDEO_DISABLE_interface_feature environment variable to 1, the feature on the interface is completely disabled. Interface is VCM or DMO, and feature is ENCODER, DECODER or QUERY (QUERY is only for VCM). You can also use UTVIDEO_PROCESSBLACKLIST_interface_feature environment variable to disable the feature on the interface for specific program. Enumerate EXE file names separated with PATH environment separator (; on Windows). If each name ends with path separator (\ on Windows), the name is directory. If each name does not contain path separator, the name is file's base name. Otherwise, the name is file's full path name. Note that case sensitivity on name comparison follows system's behavior. i.e. it is case insensitive on Windows. Examples:

Hi, guys.
I have a problem. Starting from codec version 20.4.0, when was added new feature "to disable specific codec interface based on process name or completely", I can't open codec's configuration window in Vegas Pro NLE. "Configure" button is inactive. For example, there is no such problem with VirtualDub. So I stuck with codec version 20.3.0. Is there any possibility to do something with that? Umezawa Takeshi wrote, that everyone can manually enable/disable this feature (if I understand correctly), but I am not a programmer and absolutely don't know how to do that. |

Probably Vegas passes wrong option to codec. (i.e. it is Vegas's problem)
Technical explanation: Since 20.4.0, VCM version of UtVideo strictly checks the option that passed to ICOpen (https://docs.microsoft.com/en-us/win.../nf-vfw-icopen). If wMode parameter is not ICMODE_COMPRESS, codec clients cannot call ICConfigure, the function to configure encoding option. Last edited by umezawa_takeshi; 12th July 2019 at 19:21. |
