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

Seems fine for me.<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. 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>
<br>
Tried both TFF and BFF<br>
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]

><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>
