    Sounds like a PEBKAC error to me.

  2. pebcat error? is a broken codec? however starting from the c0044out.avi is there a way with ffmpeg to half duration?

  3. Once again, many programs are confused by field sequential encoding. The result is often duplicate frames and/or confusion about whether the fps is the field rate or frame rate. And the AVI container is especially unsuitable for field sequential video.

    You can demux to a raw h.264 stream (to eliminate the container level fps value) then mux the h.264 stream into an MKV or MP4 container. ffvideosource() will then decode the video with the correct duration but it will double the number of frames (duplicates) and double the frame rate.

    Or you can patch the AVI header to say it's 50 fps.

    @marcorocchini, sorry for any jab or jest there, or sleight. It wasn't mean derisively (well, much), but it was meant to bring out an important point.

    We're up to 95 posts on this one thread alone, which is truly a continuation of a long list of threads all of which amount to a similar longstanding problem of yours.

    There's a joke in English:
    Patient: "Doctor, it hurts when I do 'THIS'!" (demonstrates)
    Doctor: "Well then, stop doing that!"
    Except these threads have amounted to:
    @marco: it hurts when I do 'THIS'
    @VH: well then, stop doing that
    @marco: but,...it HURTS when I do 'THIS'

    Even cats can learn (and change!) when something doesn't work for them. I beg you please to reconsider your convoluted workflow.

    the avi header is managed by the AVI MUX - qcap.dll? just to do a proof: is there another avi muxer that can replace the microsoft ones?

    thanks

  8. The frame rate in an AVI file is just two values in the header. Change them with a AviFrate, a hex editor, or a patch program.

    fps denominator, fps numerator:

    Of course, this isn't really a fix. It's a workaround for h.264 decoders and programs that don't handle field sequential h.264 properly. If the tools ever get updated your AVI files will be screwed up.

  11. I try to do this:

    convert C0044cat.avi to a MP4 that should be PAFF (scan type: interlaced, TFF)

    https://www.dropbox.com/s/ezlgln3kqmgtn6c/c0044cat.avi?dl=0

    C0044cat.avi is a mpeg-in-avi file as output x264 from the speed razor nle. But I need to have a mp4 file

    ... if possible without recompress/transcode/loss of quality ...

    How can I do?

    What's wrong with using ffmpeg to re-mux?
    ffmpeg -i c0044cat.avi -c:v copy -c:a copy -f mp4 c0044cat.mp4
    pause
    That clip reminds me of the old country. Is that grass/weeds on the tile roofs I see? I'd hate to go out there and weed-wack the roof!!!

    The AVI is MBAFF, not PAFF.

  20. who can help a ***?

    If I try to export in mp4 using **** ***** 5.51 for*** Rev.3 I cannot because it can use only the directshow codec that output in avi

    (in the case of mainconcept h264 encoder I have to set - in the "advanced settings" -
    Timestamp pass through mode=AVI compatible
    Output Mediatype=VSS) this because **** ***** 5.51 forCats Rev.3 can manage only the AVI MUX filter present on the directshow (qcap.dll) and not a MP4 multiplexer

    So i try to modify the export module of **** ***** so that - when I clic on "AVI Config..." it point on a MP4 multiplexer, and not at the AVI Mux filter

    https://www.dropbox.com/s/vkg2ptnbbzr3boa/mediaPostGeneric.rzf?dl=0

    https://www.dropbox.com/s/446cji827sjm39i/ISWML.dll?dl=0

    Initially I was thinking that this module (mediapostgeneric.rzf) point to Avi Config though the CLSID... but I cannot find the same CLSID CLSID: {E2510970-F137-11CE-8B67-00AA00A3F1A6} on mediapostgeneric.rzf

    really I cannot find CLSID: {E2510970-F137-11CE-8B67-00AA00A3F1A6} in any other file of **** *****

    but seems to me that mediapostgeneric.rzf is referring the AVI mux multiplexer through the ISWML.dll file attached

    LOST in CAT! because I'm not able to replace the "AVI Mux" pointer with another multiplexer

    I can not understand how ISWML.dll calls the window "AVI Mux" and the directshow filter qcap.dll unless it does so through the CLSID, who tells him how to go to use that one?

    If in mediapostgeneric.rzf or ISWML.dll was present the CLSID of the pointed filter I should change this to point to a mp4 directshow multiplexer, but... there is no clsid and I cannot understand how it point to the qcap.dll avi Mux
