Encoding lagarith from the commandline
Could somebody suggest a 64bit compatible way of encoding a file to lagarith from the command line?
Like ffmpeg would be good, but it doesn't encode, it only decodes. Preferably an exe/bat file (and not scripts or avisynth) |

why do you need lagarith?
ffv1 offers similar compression efficiency and it is available in ffmpeg

Does it compress as good? I've heard lagarith is a far better. However I also need something with a directshow codec (that works on 64 bit Windows 7) - lagarith has that, does ffv1? |

One way i can think of is saving virtual dub processing settings and loading them via the command line for vdub.exe, but can't say for sure this will work with 64bit though... And virtualdub can't save/encode to any other container than avi, so a remux would be needed later if that is not your wanted container.

ffv1 is lossless obviously. it is also available via ffdshow (encoder and decoder)

Huffy is obviously lossless, but has a setting that can make it lossy. So there is nothing obvious about anything. Especially since there seems to be 50 different settings
Indeed, and its output crashes Media Player Classic. But the files do seem small |

That's easily falsified. Choose a colorspace that involves color subsampling the input and it's no longer lossless. Either way, his question had to do with if there were settings to make the codec lossy to improve compression. All you had to say was "no".

It supports YV12,444P,422P,411P,410P,RGB32, but I take it from your reply that none of those colorspaces use subsampling. What is the difference? Also, for "Coder Type" spawnbsd suggested AC (VLC seems grainy) ? "Context Model" small or large? Also, are there resolution limits? Last edited by Foofaraw; 31st July 2012 at 18:12. |

It varies. It can be 3d rendered (no settings for color space), it can be camcorder, and sometimes external sources (don't know what space they might be in) I might add that ultra high commercial quality is not required - as long as it looks sensible on a TV via HDMI its probably fine I tried running something through vdub and it says input was YUV420 and output became RGB888 - i couldn't really tell the difference.

The input format (YUV420/YV12) has a halved color resolution, for example. You won't see a difference going from YV12->RGB24, but you might be able to spot the difference in RGB24->YV12. |
