  why can’t I output to HDV?

  Posted by Dan Freshman on May 16, 2011 at 5:54 pm

  Hello,

  I have a comp in after effects that I am ultimately trying to deliver in HDV 1080i. However, I am not seeing any options for this is after effects output module or in adobe media encoder. Am I missing something obvious?

  thanks for any help

  It may be that AE and AME can’t access the codec. I wouldn’t want to deliver in such a heavily compressed GOP based, interlaced codec. I’d use 8 or 10 bit Uncompressed 4:2:2 or Apple ProRes.

  thanks for the response..It is going to be put into an hdv timeline in Fcp eventually. If I am making this comp from scratch, is it still best to deliver uncompressed?

  I’m on a pc without pro res codecs, what would be the best delivery codec?

  thanks for the help

  I’d still deliver uncompressed even if it were for an HDV timeline.
  Think of it this way. If you were importing graphics done in PhotoShop would you convert them to HDV first? Always use the highest quality source available IMHO.

  Can you export 8 bit Uncompressed 4:2:2?

  Yes I can export to uncompressed YUV 8 bit from after effects. I will try and do that….just for my own understanding, if it is going to be rendered in hdv eventually why not do it now? Or when it is put into final cut, will something else occur?

  thanks again

  While the timeline may be HDV the export will likely be something else. HDV is not a typical delivery codec. Also a higher quality source may allow them better compositing if they’re adding anything.

  As per my example above with Photoshop, one often imports .psd files into Final Cut regardless of time line codec. Just ’cause you got moving pictures from After Effects doesn’t mean you should then resort to handing off a heavily compressed file to the client. Graphics, whether still or motion, should be as near uncompressed as possible in almost every case I can think of.
