Targa Frames Size Too Big?
on Oct 15, 2005 at 2:25:16 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 @720x540 (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):
360x270 (46.8mb)
320x240 (37mb)
240x180 (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
