For me it looks like the Set Format Preset:
PAL 576i (16:9) - DV(D and/or the File Format:
FFmpeg make up the correct DAR 16:9 here,
right?<br>
<br>
Because by Selecting the Format: <b>Raw DV </b>cause
rendering to <b>DAR 4:3</b> as shown below !
<br>
This makes me wonder if it is only the FFmepg
File formats that currently is fixed by
patches?<br>
May also other non-FFmpeg formats be affected
by anamorphic aspect ratios ?<br>

OOPS!<br>
As already mentioned, CinGG's FFmpeg-avi was saved/displayed 16:9
and the Raw DV was saved/displayed 4:3.<br>
BUT, in addition I discovered now that in both cases the images
have been cropped around, that is cut off at both sides, top and
bottom.<br></blockquote></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">I wonder how much was cropped? </div><div dir="auto"><br></div><div dir="auto">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?</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><blockquote type="cite">
That is, the 16:9 avi is displayed with correct geometry, while
the 4:3 Raw DV is displayed stretched vertically. <br>
The latter get correct geometry if forced aspect 16:9 during VLC
playback..<br>
<br>
Actually, only my ffmpeg manual encoded DV-wide has got correct
DAR 16:9 and also correct geometry.<br>

And kept the full image (un-cropped).<br>

A visual tip is that this is easiest to discover and compare side
by side using large file thumbnails with (Gnome) Filemanager.<br>
