  1. Is there any way to encoding VFR using Megui?

    And if yes what the AVS script I should use?
    Quote Quote  
  2. Not directly - because avisynth is CFR only, and megui uses avisynth

    So you could use it to encode your CFR video, then mux in timecodes after

    x264.exe doesn't need anything anymore. It has everything patched in (some builds even have audio, filtering (like resize & crop) ). You can use it directly to encode VFR

  3. If uses megui to encode CFR and then mux the timecodes, the output will be VFR.mkv, right?

    yes, but I don't think you can mux in timecodes with megui, you would need mkvtoolnix separately

  5. Yes I will use mkvtoolnix, if I have an episode something.mkv, how to know if it is VFR or not
    I try with media info and it does not show the frame rate type

    mediainfo might not be correct (it just reads header information)

    If the source was VFR , and the final is in sync, then it's VFR for sure

    If it's out of sync, it's still CFR and you messed up somewhere

    The only way to be sure is to look at the timecodes (for source or export)

  8. Other question!

    I want to encode an anime episode with megui, what is best for avs script
    ffvideosource, directshowsource or something else and why?

    Any suggestion about the avs script how should it be

    source is mp4
    Quote Quote  
  9. directshowsource is the last resort ; it is not necessarily frame accurate, and inconsistent (depends on system installed codecs and filters)

    ffvideosource("video.mp4")

    if you have other filters (maybe clean up video) then add them

    What do you mean?

    size as in dimensions e.g. 1280x720 ?

    or size as in bitrate e.g. 5Mb/s ?

  12. I mean the output size

    size as in dimensions e.g. 1280x720, =)

    size in megabytes, 250 MB, 300 MB or what?

    I mean the output size in megabytes

  13. filesize = bitrate x running time

    megui has a bitrate calculator in the tools menu

    choose whatever you want . Higher bitrate = higher quality, if everything else is constant

    If you don't know what to choose, use CRF encoding or "constant quality" encoding. Lower CRF values give higher quality and larger filesize . Most people use around CRF16-22 as a starting point
