Thanks for the research Scott. But why do I need to make the initial AVI?
Couldn't I just take all the POV frames, add the music (hmm, I guess the
timing would be off by a factor of 2 as I always compose the music while
viewing the animation in Premiere - actually I guess I could just run it at
2x speed), then select Interlace Consecutive Frames to create the one and
final AVI Just curious why I can;t work directly from the POV (Targa) frames
and output just one AVI file with the options you describe...
Thanks again. Really big help.
D.

OK.

You'll need to render a non-interlaced AVI in Premiere using the files
generated by POV's field rendering options - basically this will
contain two image files for each 'frame'.

When you have the AVI you need to put that in a new Premiere project
and then set the interlace properties for that AVI clip as Interlace
Consecutive Frames.

Render a new AVI using this and you should have a properly interlaced
AVI.

The stuff below is cut and pasted from the Premiere help files.

---Premiere Help---
To specify field processing options for a clip:

1 Select a clip in the Timeline.

2 Choose Clip > Video Options > Field Options.

3 <snip>

4 Click one of the following Processing Options:

 <snip>
Select Interlace Consecutive Frames to convert pairs of
progressive-scan (noninterlaced) frames into interlaced fields. This
option is useful for converting 60-fps progressive-scan animations
into 30-fps interlaced video, because many animation applications
don't create interlaced frames.

Well, the 'Interlace Consecutive Frames' setting is a per clip setting
- that means you'd have to enable this setting for every .tga file! 
By rendering a non-interlaced AVI first and then using that as your
clip in a new project you only need to enable this setting once.

However .... bad news .... I've just realised that the 'Interlace
Consecutive Frames' doesn't produce the result you need ... DOH!

This is what Premiere does ...

Assume Frame 1 has two POV rendered files A & B - A is the upper field
file and B is the lower field file, Frame 2 has two files C & D, Frame
3 has two files E & F, etc.

The three frames appear in Premiere as

ABCDEF

We need Premiere to produce a single frame files like this ...

Frame 1 = A & B
Frame 2 = C & D
Frame 3 = E & F

But, Interlace Consecutive Frames does this ...

Frame 1 = A & B
Frame 2 = B & C
Frame 3 = C & D

Your only solution is that some POVer out there has made a utility for
converting two field files into a single frame file.

Oh well,

Scott

And they have ...

use this tool http://willsoft.free.fr/bmp2avi/bmp2avi.zip to generate
correct interlaced frames (it only works on .bmp files so you'll need
to re-render in POV or batch convert them using a graphics app.

Okay, so I rerender as BMP or convert TGA to BMP, then run this util and
create the AVI, then I can use the Premiere Interlace Consecutive on the
entire AVI file, then drop it into the encoder, then sit back? Or do I still
need the Premiere step?
Thanks again Scott. Getting real close now!

Since the util creates the interlaced AVI for you, I don't think you
need Premiere - just drop the AVI directly it into the encoder.

(I'm not 100% sure on the 'not-needing-Premiere' bit since I haven't
used this util before - when I get some time I'll give it a try
myself)

Scott

Well, I've tried it out and you shouldn't need Premiere - you can just
feed the .avi into your MPG2 encoder (I tried it with TMPGEnc - worked
fine).

Some things you need to know...

You need to ensure POV renders to .bmp files (bmp2avi requires this)
You need to tell POV to render twice as many frames in order to get
the correct number of .bmp files
You need to set Initial_Frame to 0 (bmp2avi requires this)

Cheers,

Scott
