Are TGA's 10bit?

[Nikitas]

Hello all. I am a film editor and I am experimenting with HD at the moment. I have a very simple question for anyone that can answer it. I want to export HD captured material from Premier, After Effects or Combustion.
From After Effects so far I can do it but only as an .avi . Combustion I havent tried yet. The main question here is that I want to keep the 10bits my material has and I am wondering if I can export in TGA sequence format. Will that still be 10bit?
Is there any plug-in for any of the above mentioned that will allow me to export to 10bit TGA sequence or even .avi and so be able to keep my HD quality?
Anyways these are a lot for a first time post, so I stop here and wait for your help.
Thank you everybody.

hmm i've never heard of a ten bit targa before. i use targa files every day for textures in our engine.

as i know it
1 bit - all black and all white (no gray)
8 bit - gray scale
24 bit - rgb with no alpha
and 32 bit - rgb with alpha

hope this helps

A 32 bit with alpha is 8steps image. I am talking about 10 steps image here. think of it like this: the degrading of colour in 10steps is more smooth and accurate than in 8steps. I probably misled you with that 10 bit in the first place. Still the question remains the same, but thanks for the answer.
In video and film all equipment are using 8bit engines. In HD (high definition) the engines are 10bit for proccesing colour which is different from the 24 or 32 bits of the TGA's.
