Hi,
Someone must have tackled this before and found a good working high-quality solution. To find out this from scratch would require lots of experimenting, therefore I turn to you - the experienced and helpful fellow forum members.
First, I am not looking for a DVD authoring program. I am just looking for the best render option for how to export the material to the authoring program (DVD-Architect from Sony). I want to avoid another quality compromising unnecessary decode-encode process during the authoring.
The clips on my timeline are 1920x1080p 25fps (XCAM 10-bit) files with 1:1 ratio pixels. The project and timeline are set to the same resolution and fps.
The DVD's will be SD (720x576) 50i, with a pixel ratio of 1.33:1 (to keep the widescreen format). Sadly the DVD (PAL) format does not support progressive video...
From the DVDA's manual, I can read the following. "If you're rendering with a different application (other than Vegas), the following setting will produce a compliant PAL MPEG-2 video stream:
704x576, 25 fps, 4:3, 30 max GOP, 9.8 Mbps max bitrate. If you're rendering with a different encoder, ensure Low Delay is turned off."
The audio must probably also be rendered separately, either as AC-3 or PCM.
Considering all parameters; required file format (MPEG- 2), limited bit rate of 9.3Mbit/s, 25p conversion to 50i, pixel aspect ratio conversion, as well as the colour spaces - what should the export format be to keep the best image quality? Would it be necessary to filter (blur) the original video somehow, not to cause a too sharp end result - that might create visible pixel edges or other artefacts in the PAL SD video? And is the interlacing and issue when going from 25p to 50i?
Additionally, the 704 horizontal pixels equals a 1.3636:1 pixel aspect ratio? Shouldn't I render out 720x576 to get 1.333:1 pixel ratio, which one is correct? I remember that the picture aspect ratios differ between widescreen HD and SD. Would be nice to convert in one pass so that there are no black borders after the conversion. And what does that "low delay must be off" refer to?
Too many parameters... Thanks in advance for your insights into this problem. Cannot avoid this DVD export need, some people still want optical discs...
Cheers,
Christian
