Fourteen hours to save to an avi with Studio 8.10

[Will Hay]

I captured (as I always do) 90 mns of VHS footage with Studio 8.10 from my ADVC-100.
I edited, clipped and added a few transitions and then split a few scenes up and lightened the image from the default (50) to somewhere around 60-65.
I left it to save back as an avi (DV video encoder, 720 x 576; same as I captured from the ADVC-100; I prefer TMPGEnc for encoding, hence saving as an avi) and seven hours later it wasn't even half way through.
I stopped it (I couldn't wait) and opened up the project and removed all the adjustment I'd made in the lightness tab, setting everything back to default.
The resultant saved file took 40-50 minutes.
Should it really take so long???????
I mean, fourteen hours is just ridiculous and when I've done this before, albiet on smaller footage it didn't seem to be anyway near as long.
I appreciate in PAL land a 90 minute clip has 135,000 frames (25f/sec) and that's a lot of frames to lighten but even so...
...is fourteen hours normal?
That's like nine hours for every hour of footage!
Anyone else regulaly lighten footage in Studio 8?
Thanks,

Sense you were altering every frame (adding brightness), it's understandable that it would take alot of time to re-render. When you removed the brightness addition you made it possible for most of the footage to just be copied digitally, while only the transistions needed to be re-rendered.

Thanks, I figured it was normal and knew it was 'playing' with every frame; I just wanted to make sure it was happening to everyone else too
Thanks,
