frame editing

How do you go about editing a single or a series of frames ?
This involves making changes in an image editor, say adding a ship in the distance or a building etc.

To my knowledge in VV, to edit a frame or series of frames, you can export as jpg's or PNG and reimport and re-render.
This means the rerendered AVI has become as detailed as the jpg's it was created from.

Is it possible to get AVI edited without losing quality?

I think I have heard of this referred to as EDL (edit decision list)

Perhaps there is a .mov and apple solution.

you can save AVI's in uncompressed format (check out the default uncompressed AVI template)... it takes up a huge amount of disk space.. but that is the only way you can end up with a truely loss-less format.

I would be happy with AVI DV, either will do, as the loss in rendering is just DV compression.

But the loss involved in exporting to jpg is huge.

Editing frame by frame must be possible, and I'm sure these big production houses do it from time to time.

How do you maintain AVI or DV AVI quality ?

(Or have I got it wrong is VV filling out the AVI from the jpegs and being effective - perhaps not coz a whole bunch of people were telling me AVI is NOT 800x600 jpgs rendered together.)

I'm not dead sure, and can't check right now, but I think the Render Image Sequence script gives you the choice of .jpg or png.

Edited addendum: I've now been able to check it out, and yes, you can do it with pngs.

This way, you'll have no loss in quality.

Yeah, PNG's from Vegas aren't compressed by defailt, but neighter are the JPG's. I export the PNG's though.

Or... :) You can render out the part you want to edit into a seperate DV AVI file, then use TMPGenc (www.tmpgenc.com) to convert to frames (as BMP, TGA, or JPG). This exports frames a LOT faster then the Vegas script. And I mean A LOT.
