I think it would be useful to have x262 encoding working with VirtualDub2, especially as we can now save directly to the .mkv container...

Thanks Groucho for the binaries.
I took a quick look at the help, leaves me a little confused. The help always refers to x264, is this just sloppiness? And then I do not see the option to output an m2v elementary stream, are the devs serious about this? Dunno, looks I will stick with HCenc and FFmpeg for my MPEG2 encoding needs... |

And once the elementary MPEG-2 has been extracted it can be muxed into other containers...

By the way, thanks for the updated binaries, Groucho! Quote:
Although I've automatized everything via bat, it would be useful to have it available on VirtualDub as well. For the records, by "VirtualDub" I mean VirtualDub2 Filtermod of course. |

Already trimming them so they can regrow in the process.

MPEG-2 is still absolutely mainstream, widely deployed, and utterly critical in professional workflows, mostly in broadcast. Just a few examples:
- OTA broadcast via ATSC is still MPEG-2. - Many cable systems still use MPEG-2 for linear channels due to legacy settop boxes (often live transcoded from the "real" AVC used by the rest of the system). Lots of cable VOD is still MPEG-2 as well. - Many legacy HD and SD linear channels are originated on satellite via MPEG-2 - DVDs are still very much a thing. - Most linear TV channels play MPEG-2 files out of their video servers. IMX is common for SD, and XDCAM HD422 is common for HD. That last one I know a ton about as I worked on the ingest / workflow side of broadcast for many years. Most channels have huge libraries of content in their "house format" which tends to be MPEG-2 based for simplicity and consistency with files ingested 10+ years ago. You change as little as possible when taking channels to air. Storage is definitely expensive, but the businesses tend to prefer spending the money on the old file formats since it mitigates risk elsewhere. Thankfully nobody doing OTT streaming uses MPEG-2, because as we all know it's utterly outclassed by 2+ compression format generations and 20+years of development.

I would like to know why x262 isn't a pure MPEG-2 encoder yet... not sure whether it's impossible to get rid of the H.264 encoder parts, or whether the developer was just too lazy Anyway, I only knew that x262 suckED in the beginning... but yesterday and today I gave a second chance to the binary. Well, it's much better now, I have to say. It does not limit the GOP length, accepts the linear quantization scale and custom matrices as well, and is fast. *THUMBS UP* |

Hi Sparktank, I needed to encode for DVD recently, and used HCenc also.
Interested to try x262, are there any comparisons available comparing x262 with HCenc? Or have you found any result from your own testing? Last edited by outhud; 24th July 2019 at 11:37. |

I'll be doing some testing within the next couple weeks. I just need cannibalize my computers. The old one has the really good drive that does UHD-BD's.
From some limited testing yesterday, it's quite decent but needs a lot of tweaking. Quote:

but the visual quality AND the small filesize were similar to the results produced by the (already-old) Mainconcept Reference MPEG-2 Encoder. Last edited by filler56789; 24th July 2019 at 21:21. Reason: typo |

So to use an analogy, x264 and x265 are like cousins. x262 is like x264 grew a second head. |

Since you're resurrecting the topic, speaking of MPEG-2, will the FFMpeg encoder ever be properly multi-thread?
It's painfully slower than it could be right now on my 28c/56th... Sure, I can run multiple encodes at a time but still... |

Since patents on mpeg2 have now expired I expected a renewed interest in this free codec.
Curiously, despite the age, still mpeg2 video encoding offers many free alternatives to pick: x262, HCenc, ffmpeg and, if you have a recent intel cpu, qsv encoding (through ffmpeg as well). And all them can run cross platform (HCenc runs smoothly under linux using wine). It would be great to see a great, comprehensive comparison (speed-wise, quality-wise, feature-wise) among them all. |
