encode at bitrate given/obtained by a crf encoding
microx264 allow this, could be useful mainly for testing purpose just do a 1 pass crf , then do a 2nd pass using the average bitrate from first pass BHH

Doing a 2-Pass encode at bitrate X and doing a CRF encode at the same bitrate X will give (almost) identical results - the only difference is that with CRF you don't know X in advance. The difference in quality will be so small, that you probably wouldn't be able to spot it. So if you need to hit a specific bitrate, then do a "plain" 2-Pass encode. If you want to preserve a certain level of quality (roughly), then use CRF mode at your favourite CRF value. First doing a CRF pass and then doing a second pass (2-Pass mode) based on the bitrate/stats from the CRF pass won't improve quality over the initial CRF pass. Since this GUI was written for simplicity and since it certainly doesn't try to be a "swiss army knife" for x264, I won't add an automated method for such "placebo" features. There is no real use for it (at least none has been presented to me) and it potentially confused people. Plus it unnecessarily complicates the code...

you just got a more bitrate variance with the insurance of "fixed" crf value
again, not for daily use, but fun for testing BHH

And thus nothing we need in a "Keep It Simple Stupid" GUI

Updated x264 to r1510 (Komisar's builds). Now with full "BluRay" (NAL-HRD) support.
Please see the commit message for detailed info on how to produce BluRay-compliant streams: http://git.videolan.org/gitweb.cgi?p...d723c7d0c9f505

Why did it disable? How do I make sure it is enabled when interlaced is found? thanks |

(2) If you really want to enforce progressive encoding of interlaced source, then you can specify "--no-interlaced". Probably not a good idea though! (3) The warning about "interlace + weightp is not implemented" means that x264 cannot use both, weight-p and interlaced mode, at the same time. It is not implemented (yet). (4) It is 100% safe to ignore the warning. Basically it just informs you that interlaced mode is used, and thus weight-p (weighted p-prediction) is not used.

I had another question:
Is there a way to load two m2ts files and merge during encode? At this point I'm merging them in tsmuxer and loading that file into x264. Could save a step, but not at the risk of complicating a nice program. Last edited by archaeo; 31st March 2010 at 19:24. |

Code:
a = FFmpegSource("C:\Some Folder\File1.m2ts") b = FFmpegSource("C:\Some Folder\File2.m2ts") c = FFmpegSource("C:\Some Folder\File3.m2ts") return a + b +c

Hi there....how can I fix this:
When I feed the launcher with this avs-script: Quote:
When I remove the resize-filter from the script...it does work properly. Any ideas? |

Sounds like an Avisynth issue. Maybe an x264 issue. Most-likely not related to my GUI...

No matter what GUI front-end you use, your Avisynth script will always be handled by Avisynth, i.e. the GUI doesn't make a difference here.
Well, the only difference between MeGUI and my simple x264 launcher is that my launcher uses avs2yuv.exe instead of passing the script to x264.exe directly. Try something like avs2yuv.exe "C:\Temp\Your Script.avs" -o "C:\Temp\Output.y4m" with your script and see what happens...
