Well, maybe you saw I actually had root

write to a directory I had renamed 😳<br>

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

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. <br>
<br>
I felt I had not completely control over what happened.

<div dir="auto">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</div>

Could you think of making a couple of CinGG demo videos to manual,
for the following use cases:<br>
<br>
1) Rendering HD(V) to 16x9 SD-DV (anamorhic down-conversion with
oversampling)<br>
2) Rendering HD(V) to 16x9 DVD video <br>
3) Rendering 16x9 DV to 16x9 DVD video<br>
<br>
Another, very illustrative reference I will suggest to this manual
topic(s):<br>

<div>By the way, here is the procedure I think did work
for me:<br>
<br>
1. Loaded the HDV <br>
2. Started File > DVD Render, selected Format: PAL
(25.00) 16x9, Scale: Scaled, and OK<br>
3. Batch (DVD) Render window opens<br>
4. Started File > Render and closed the Batch Render
window<br>
5. Edited file path and file name, File Format: FFmpeg -
avi (or dv), Audio: Preset avi_pcm, Video: dv_pal.avi,
and before OK!<br>
6. Open Set Format, verify the Canvas size has changed
to 720x576 and DAR 16:9, Switch Interlace mode to:
Bottom Field First, OK<br>
7. Lastly OK on the Render Window (5) and rendering
begin<br>
<br>
Confusingly 2. and 3 partly may create DVD directories
which can be deleted.<br>

<div dir="auto">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...</div>

<br>
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.<br>

1440*1080 clip and then<br>

WITHOUT any scaling on top?<br>
><br>
--------------------<br>
Yes, I loaded the anamorphic 16:9 HDV
1440x1080 clip and then rendered<br>
it using Set Format Preset PAL 576i
(16:9)-DV(D) - without any scaling<br>
on top.<br>
According to my understanding this should
down-convert the full source<br>
image to DVD 16:9 anamorphic format, which at
playback should display<br>
upscaled 16:9 screen.<br>
That is, just as in my first post<br>
<br>
4 b) FFmpeg transcode HDV to DV-wide<br>
ffmpeg -hide_banner -i hdv07_05.m2t -vf<br>
scale=720:576,setsar=64/45,setdar=16/9 -c:v
dvvideo -c:a pcm_s16le<br>
dv07_05_wide.dv<br>
----------------------------<br>
DVD Render Format autoscales the input HDV
format to fit the selected<br>
16x9 DVD output format.<br>
When input format and output rendering formats
are identical, it seems<br>
that nothing needs to be set/edited manually
in Set Format.<br>
<br>
Then the unavoidable request/suggestion:<br>
Could correspondingly different I/O format via
selected Presets also<br>
bake in Autoscale as default (beside color
space mentioned before) ?<br>
(refer to the: -vf
scale=720:576,setsar=64/45,setdar=16/9 in the
ffmpeg<br>
line below)<br>
---------------------------<br>
I think no, it was intended to give users
control over what kind of <br>
filters they want to apply. Even with ffmpeg
you still manually add <br>
scale filter ...<br>
-----------------------------<br>
Fx. the DVD Render window has a Scale dropdown
menu, where "Scaled" is<br>
default.<br>
The other options are None and Cropped
(various).<br>
As an additional test I rendered with None,
and then got similar 16:9<br>
output displayed as ffmpeg-avi.<br>
(The Raw DV differed with 4_3 display)<br>
============<br>
<br>
Here we are currently. I hoped to get this
down-convert/scale Rendering <br>
via Set Format Preset as easy as corresponding
DVD Render (and <br>
BD-Render) using a user selectable "Scale
switch". If this is not easy, <br>
possible or desirable, I hope you can add the
detailed Scale steps in <br>
this case from here, because I have no
experience with this yet.<br>
