Adding Transparency
I have digitized interlaced analog content. I want to make parts of the video transparent.
My current plan goes as follow:
1. From Premiere Pro, Export clip to film strip
2. Open film strip in Photoshop and paint unwanted section in green
3. Bring into Premiere Pro and use chromatic keying(?) to remove the unwanted sectionI know that this will be time consuming as for each second of film I’ll have 30 frames to do. The clip in question is sports related thus there’s not really static elements that could be targetted.
Thoughts on this process?

If you are going to do it that way, just make the background transparent in Photoshop and the alpha should be retained back in Premiere Pro if you do a series of files that has alpha (.png, .tif, .tga, etc). There is no reason to make it a color then key the color.
You could always roto it in a compositor.

I was thinking of exporting the clip using the *.flm exention (Filmstrip). All the frames are contained into 1 single file. Can you do this with other formats too such as the ones you mention?
Thanks for your reply.

Dan,
If you export series of files, they will be individual files, typically an editor or compositor will have a checkbox for “numbered files” so you select the first one then the rest in the series will be there and look like a piece of media in the software. The filmstrip is how Photoshop does this, but I have not used that in a long time. My recommendation would be to make sure you see through to the back in photoshop (no background – just double click the background and use the name Layer01) so it’s using the alpha channel instead of keying out the color. I don’t know how the filmstrip will deal with an alpha though.
Sorry I can’t be more helpful.
