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></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">This is possible! I basically never used non-ffmpeg video encoders!
