Hello,

My colleague and I have to deliver a project on both BlueRay and DVD.
We have a large project file in Premiere which (according to the premiere render queue) will need about 20 hours to render. My questions are:

1) In order to render the two versions (HD for BlueRay and SD for DVD), do we really have to render twice, or does it make sense to only export the HD version and convert that file to SD?

2) Is it possible to render in parts and join these files afterwards without having to compress again?

Any help would be greatly appreciated,
cheers,
Jan

I am just wrapping up a 2hour 20 minute hd project that also r4equired an SD version of it.

My work flow was as follows: (I know there are others with better info I am sure )

captured HD to cineform avi at best quality.
Edited and color corrected in Hd.
Rendered and burnt the blu ray disc
Rendered to 16:9 720x480 Sd with mainconcept preset, used pcm stereo instead of ac3
built dvd in Dvd architect.

The rendered SD is actually a little finer in appearence than shooting or downconverting in camera to SD.

Hopefully others can give you more info that will help you out.

export it to After Effects and add to render queue - and render twice.
hd blu ray uses h.264 and DVD uses mpeg2. your dvd will look much worse if you use the blu-ray version to compress an already heavily compressed codec.

Thank you very much Sareesh and Dale, now I know that I shouldn´t recompress the blue ray files.
I am still very curious regarding my other question:

Is it possible to render a timeline in parts and join these files afterwards without having to compress again? Anybody?

Thanks in advance,
kind regards

Try MPEG Joiner/MPG Joiner helps to join mpeg/mpg files. (http://mpegjoiner.net/) - I have not used this particular software, but did use a similar one for joining vob files, and it worked fine.

Render as a 16-bit TIFF, targa, JPEG 2000 or motion JPEG image sequence. This is a great master format (it doesn't involve sound - that needs to be done separately as a WAV file). This way, even if your computer crashes while rendering, you don't have to start all over again.
