To my eyes, HC gives better results for almost every source except high-speed interlaced for which I prefer the results of ProCoder. Maybe that's an issue of motion detection, maybe not. I have, however, noticed on quite a few inspections that ProCoder does a very good job of keeping the chroma of edge pixels of the 8x8 blocks quite similar. HC doesn't do as good a job. Perhaps, just perhaps, there is something to be mimiced here. If the edge of one block is more similar to the edge of the adjacent block, that should yield a smoother image as seen by human eyes, which are especially attuned to motion and straight edges. Why do I say this? I'd love to see HC outperform ProCoder.

I'm having trouble getting my AviSynth files to load.
I have AviSynth 2.5.6.0 (checked in HC) but when I try to load my AVS file, the words "AVS file opened" flash in the info box for just a sec, and then they disappear and the input file name remains unspecified. My AVS file is just an AviSource line, loading an AVI. The AVI is encoded with Arithyuv Lossless Codec. The AVS works okay in MPC. HC can open AVS files with an MPEG2Source line. EDIT: Also tryed AviSynth 2.5.5, no luck. Last edited by PlazzTT; 12th January 2006 at 22:15. |

Does it work with DirectShowSource? I don't know if Arithyuv has a DirectShow decoder though. I've sometimes had problems opening files encoded with ffdshow's mjpeg codec with AVISource, but with DSS they work just fine.

Many Avi Sources will be other than YV12 which can be the problem because HC only takes AviSynth scripts that output YV12 Put info() in your AviSource scripts, it will tell you what your script is outputting. Use ConvertToYV12() to convert before HC ATM it appears that HC is trapping the incorrect input file but doesn't tell us about it, just ignores it. http://members.aol.com/avsfilmcutter If you where using FilmCutter you could just hit F8 to see your script output properties. You can even test your script for proper ColorSpace when you launch your encoder from FilmCutter. <- shamless plug, sorry |

In order for DSS to output YV12 when using a clip encoded as YUY2, DSS in using a color space conversion filter which you may not have any control over. You do not need DSS to input the source, so you again a little speed, much better seeking. And IMHO something that will work next month as it does this month. Good luck Last edited by Ebobtron; 13th January 2006 at 13:49. |

You can force DirectShowSource to output the colorspace you want. If you know that the original colorspace is YUY2, just use the parameter pixel_type="YUY2".
As I was unsure whether the codec contains YV12 stuff or not, I suggested trying DSS In fact, AVISource will always output YV12 first if the codec supports outputting it. That's something you need to remember for example when dealing with YUY2 capture files.

about ffdshow, avisource and HC:
i find anything that ff_vfw.dll decodes crashes HC on opening. with directshowsource it doesn't. strange. i've tried 3 ffdshow builds, and several different codecs within ffdshow and all die. but with directshowsource it's fine... peculiar.

wee! i just discovered this morning that if you encode off the network and the computer your files are on crashes, HC keeps patiently waiting until that machine is back, and then continues encoding! that's very cool

Hi Hank,
Just noticed something in the log-file while fooling around: I was encoding a 23.976fps source with a width*height of 720*576. Here's part of the log: Code:
-------------------- | source stats | -------------------- nr. of frames in source: 127690 width*height: 720*480 fps: 23.98 See you, Jan Peter

I just wanted to say that this encoder has been doing a superb job for me with my interlaced hi-8 home movies....slow on my pIII 866 but well worth the overnight wait!!!! I can't wait to see new versions!!!!

I is sure Hank will fix. As for the rest ??? 23.976fps is NTSB Film. |

Hi guys,
sorry for the late reply... buzy few days. I was in fact trying to use dgpulldown to do a ntsc > pal conversion. So i had to use that combination of weirdness... Which introduced another thing: When i muxed it all together, muxman complained about a buffer underflow being detected. Shouldn't that have been detected by HC? JP

iam planning to encode certain files using q5 + dvd compliance bitrate limiter, however iam seeing some weird seeking problems using either mplayer or powerdvd (lenght is changing in powerdvd, mplayer cannot decide where it is also - looking at the osd)
virtualdubmod seems to open them fine, also no problems with mpc. ini file is simply: *MAXBITRATE 8000 *FRAMES 1 15000 *ASPECT 4:3 *CQ_MAXBITRATE 5.000 *MATRIX mpeg Last edited by smok3; 2nd February 2006 at 09:30. |

@ scraper:
it might just play fine anyway... different programs have different ways of measuring bitrate, as do different playback devices. HC (i think) measures bitrate GOP wise - it measures bits/sec for each GOP, but i'm not aware if it takes other GOPs into account. anyway, it should be fine, but burn a RW and check in a standalone or two
