Dust and scratch removal.
Greetings,
What is the procedure for removing dust and scratches from a hi-def image sequence in Sony Vegas?

I would do that in Photoshop. Vegas doesn’t really have any photo touch-up tools.

Was this some effect someone put on it? I don’t get how HD video could look like that. There are some video enhancers that can remove some noise, but youd have to render the seq to video first.

Hi John,
I realize Photoshop can be used to remove dust and scratches from individual frames but how do you get the frame or frames that need touching up out of Vegas and into Photoshop? Once they are repaired in Photoshop, how do you physically replace them back in the Vegas timeline at the proper place?
Thanks.

Hi Danny,
The scratches I am referring to were on the original 16m film negative. This negative was then transferred to hi-def files through a Rank-Cintel scanner and saved to a hard drive which was used to ingest the material into my Vegas timeline. The hi-def file didn’t create the scratch it just copied it from the 16mm original material.
I still need to know the physical procedure needed to remove the scratches from the hi-def image. I know it should be taken into Photoshop but how do you get the frame or frames out of Vegas into Photoshop and then back into the Vegas timeline?
Thanks.

I believe that Photoshop CS4 Extended can open video files and process them. Even if it couldn’t, you would output the video as a still image sequence and apply the filters in Photoshop in batch mode and then load the video back into Vegas from a still image sequence.

You first have to save off – or “render” – the segment you have that has scratches and dust (should be rendered as a format called “filmstrip”; don’t know if Vegas can do this). This formatting turns your segment, clip (or event, as Vegas calls it) into a series of jpgs. It will be HUGE! (If your movie equals 24 frames per second; that’s 24 jpgs for each second of your film.) Then open it up in Photoshop as “filmstrip” and remove each piece of dust or hair by hand from each jpg, re-save it, then open it back up in Vegas (again, if Vegas will accept “filmstrip”.)
This makes for a many-generationed film, im my mind. And since I don’t have Photoshop anyway, what I do (I’m removing some specks and hair from a production, myself) is, in Vegas, at the point where the speck or hair is located, I go up to the video track above it and place a mask there. When the event is played back: speck-b-gone!
Now, it’s a (somewhat) tedious process to create this perfect mask (If you’re interested, I’ll explain in a later post), but what you’ll end up with is a rendered-once project, as opposed to the multi-generational way with Photoshop.
