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></blockquote></div></div><div dir="auto"><br></div><div dir="auto">well, may be just use DVD render but abort it at second (batchrender) window, and render normally ?</div><div dir="auto"><br></div><div dir="auto">if dvd render set scaler automatically you hopefully just can reuse its settings for wide dv encoding?</div><div dir="auto"><br></div><div dir="auto">but watch out for interlace reversal ... :( (tff for hdv, bff for dv).</div><div dir="auto"><br></div><div dir="auto">So may be you need more complex hdv interlaced = to frames -> scale down fields independently = > encode</div><div dir="auto"><br></div><div dir="auto">procedure ....</div><div dir="auto"><a href="https://cinelerra-gg.org/download/CinelerraGG_Manual/480.html">https://cinelerra-gg.org/download/CinelerraGG_Manual/480.html</a><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">If you just deinterlace then scale it will be simpler, i think.

To repeat and extract from the long thread, we can start from from my <br>
dialog with Andrew below:<br>
<a href="https://lists.cinelerra-gg.org/pipermail/cin/2024-January/007699.html" rel="noreferrer noreferrer noreferrer" target="_blank">https://lists.cinelerra-gg.org/pipermail/cin/2024-January/007699.html</a><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>
