  re-render in DVD ARchitect

  Posted by Wouter Slagter on March 1, 2014 at 10:04 pm

  To render to bluray in Vegas can be max 25 Mbps in MC/AVC or 16 Mbps with Sony AVC .
  bluray on bluray disk can be max rendered at 48 Mbps.
  So if I like a higher Mbps render rate for my bluray disk,I could re-render with a higher Mbps rate in DVD Architect, then it does not matter what Mbps you use in Vegas if you re-render in DVD Architect anyway.Correct?
  Also, if the space on the bluray disk is not full yet before final render (25 GB or 50 GB)in DVD Architect, you could crank up the Mbps just enough to fully use the disk.
  Any thought about this render/re-render procedure ?

  Thanks

  Re-rendering to a higher bitrate in DVDA will do no good. You already lose quality with the initial lower bitrate render given to DVDA.

  If you want a higher bitrate then customize the DVDA template in Vegas for a higher bitrate.

  Also do not confuse total max bitrate and max video bitrate. Also do not confuse average bitrate with max bitrate. The 48Mbps you quote is not the max video bitrate. 40Mbps is the max video bitrate. Also Blu-ray has two levels and this affects encoding options with regards to slices. This only matter when you want to push bitrates higher.

  The Mainconcept 25Mbps template is basically Blu-ray Max. Sony AVC only supports level 4.0 and if you edit that template you will still be a little lower than the MC AVC template

  Also depending on what your camera sources are, these higher bitrate AVC encodes may not improve video quality.

  You can consult this page for more detailed information on Blu-ray encode bitrate specs.

  Thanks Norman
  I rendered my footage in Vegas as
  MC/AVC/AAC-Bluray 1920×1080-24p 25 Mbps videostream
  So the best would be to keep the rendering setting in DVDA the same 25Mbps ?
  Thanks again

  You do not want DVDA to render anything you give it for best results. If you give DVDA compliant video and audio streams and everything can fit then DVDA should just burn your files straight to disc.

  Consult the DVDA help some (search recompress in the help index), but look at the Optimize Disc dialog. Make sure DVDA does not think the video or audio files needs to be recompressed. If they do not fit, then whatever DVDA thinks needs to be done to get them to fit, simply use those bitrates in Vegas versus letting DVDA recompress.

  The fewer times you re-encode your video the higher your final quality will be. To save some time, there are online bitrate calculators you can consult if you think your video might be too big.
