        Well, maybe you saw I actually had root access, but tried
        instead to
        write to a directory I had renamed 😳

        Seems fine for me.

        Yes, let us co-operate on a BD use case next, but first I
        suggest to
        complete the 16:9 HDV to 16:9 DV use case successful ;)


    well, may be just use DVD render but abort it at second
    (batchrender) window, and render normally ?

    if dvd render set scaler automatically you hopefully just can
    reuse its settings for wide dv encoding?

    but watch out for interlace reversal ... :( (tff for hdv, bff for
    dv).



    Yes, I think that can do the trick. I got it to work, but I hope
    this workaround can be more plain and clearly, if it is possible
    to "copy" the DVD Scale button in some way to the File Render window.

    I felt I had not completely control over what happened.



Heh :) In this case you hopefully can just save scale plugin/effect setting as they set up by DVD wizard for your case and then just manually apply effect over whole video track and set its parameters from profile? Even without GUI you can copy xml file from .bcast5 directory to your favorite place and then copy ot back when you need to render with those specific parameters again. Sort of settings template


Could you think of making a couple of CinGG demo videos to manual, for the following use cases:

1) Rendering HD(V) to 16x9 SD-DV  (anamorhic down-conversion with oversampling)
2) Rendering HD(V) to 16x9 DVD video
3) Rendering 16x9 DV to 16x9 DVD video

Another, very illustrative reference I will suggest to this manual topic(s):
https://www.sandelinmedia.com/widescreen/


    By the way, here is the procedure I think did work for me:

    1. Loaded the HDV
    2. Started File > DVD Render, selected Format: PAL (25.00) 16x9,
    Scale: Scaled,  and OK
    3. Batch (DVD) Render window opens
    4. Started File > Render and closed the Batch Render window
    5. Edited file path and file name, File Format: FFmpeg - avi (or
    dv), Audio: Preset  avi_pcm, Video: dv_pal.avi, and before OK!
    6. Open Set Format, verify the Canvas size has changed to 720x576
    and DAR 16:9, Switch Interlace mode to: Bottom Field First, OK
    7.  Lastly OK on the Render Window (5) and rendering begin

    Confusingly 2. and 3 partly may create DVD directories which can
    be deleted.



yeah, this is just workaround. I do not feel very comfortable doing GUI work, and I do not feel special-casing workflow into generic rendering window will be good idea...

Well, in principle I prefer to utilize and combine the best of both worlds, complementary when possible. GUI for visual overview, easy accessibility of non-familiar testing or new features/applications. CLI for effectivity, and understanding when experience, yes. When I started with CPM/DOS and Unix and Uniplex, the most were CLI based.


    Tried both TFF and BFF
    The bottom line is that this trick and workaround created DV 16x9
    files which all displayed correct due to [SAR 64;45 and DAR 16:9]  😎


but do they display smooth motion? I am still worried about field dominance :)

    So may be you need more complex hdv interlaced = to frames ->
    scale down fields independently = > encode

    procedure ....
    https://cinelerra-gg.org/download/CinelerraGG_Manual/480.html


    If you just deinterlace then scale it will be simpler, i think.
    Because we not start with upscaled interlaced SD ....



        To repeat and extract from the long thread, we can start from
        from my
        dialog with Andrew below:
        https://lists.cinelerra-gg.org/pipermail/cin/2024-January/007699.html

        =================
         > I wonder how much was cropped?
         >
         > May be I misread you but you loaded HDV 1440*1080 clip and
        then
         > rendered it into ffmpeg DV at 576i WITHOUT any scaling on top?
         >
        --------------------
        Yes, I loaded the anamorphic 16:9 HDV 1440x1080 clip and then
        rendered
        it using Set Format Preset PAL 576i (16:9)-DV(D) - without
        any scaling
        on top.
        According to my understanding this should down-convert the
        full source
        image to DVD 16:9 anamorphic format, which at playback should
        display
        upscaled 16:9 screen.
        That is, just as in my first post

        4 b) FFmpeg transcode HDV to DV-wide
        ffmpeg -hide_banner -i hdv07_05.m2t -vf
        scale=720:576,setsar=64/45,setdar=16/9 -c:v dvvideo -c:a
        pcm_s16le
        dv07_05_wide.dv
        ----------------------------
        DVD Render Format autoscales the input HDV format to fit the
        selected
        16x9 DVD output format.
        When input format and output rendering formats are identical,
        it seems
        that nothing needs to be set/edited manually in Set Format.

        Then the unavoidable request/suggestion:
        Could correspondingly different I/O format via selected
        Presets also
        bake in Autoscale as default (beside color space mentioned
        before) ?
        (refer to the: -vf scale=720:576,setsar=64/45,setdar=16/9 in
        the ffmpeg
        line below)
        ---------------------------
        I think no, it was intended to give users control over what
        kind of
        filters they want to apply. Even with ffmpeg you still
        manually add
        scale filter ...
        -----------------------------
        Fx. the DVD Render window has a Scale dropdown menu, where
        "Scaled" is
        default.
        The other options are None and Cropped (various).
        As an additional test I rendered with None, and then got
        similar 16:9
        output displayed as ffmpeg-avi.
        (The Raw DV differed with 4_3 display)
        ============

        Here we are currently.  I hoped to get this
        down-convert/scale Rendering
        via Set Format Preset as easy as corresponding DVD Render (and
        BD-Render) using a user selectable "Scale switch". If this is
        not easy,
        possible or desirable, I hope you can add the detailed Scale
        steps in
        this case from here, because I have no experience with this yet.
