  Targa Frames Size Too Big?

  Posted by Nakedmonster on October 15, 2005 at 2:25 am

  I know this has been asked a million times but my situation is a bit different. I am trying to compress this for my website. My Demo Reel is 1min 46secs. I rendered it out in Maya as Targa files. This is a modeling reel w/ turntable revolves of the models, wireframe on shaded, no texturing yet.

  The uncompressed file rendered out in AFX is 3.44GB @720×540 (this is for my VHS/DVD reel). I then stretched it in AFX to 3 diff resolutions for web using the Quicktime pro Codec (H.264):
  360×270 (46.8mb)
  320×240 (37mb)
  240×180 (24.3mb).

  These sizes look great but are much to big for web. I can get them smaller by exporting in QTpro and using other settings/codecs in AFX but they look really crappy and you can not make out the wireframe on the models. I have read through the boards and tried other solutions ect. and i am convinced that the Targa frames are just too big to begin with!1.48mb per frame).

  Is there a some way i can adjust the targa files in Photoshop to make them smaller w/o loosing quality?

  Is there some setting in AFX that will help?

  Or do i need to re-render it out in Maya and adjust something in the Render Globals settings?

  I am seriously considering purchasing Sorenson Pro but i dont want to spend the money i then find out it will not compress the vid any better than anything else i have tried.

  Please Help! I have been fussing with this for weeks and my hair is turning grey.

  Thank you

  The source frame size really doesn’t matter – it’s the output frame size.

  In QuickTime, H.264 is by far the most efficient codec.

  Make sure your settings are set to:

  Optimize for Download
  Multiple passes

  And especially, SET A BITRATE. By default, you don’t get one with H.264.

  The size of your file in MB will be:

  (bitrate in Kbps * duration in seconds)/128
