Default Underexposed clips questions

Someone who shot with me underexposed a few key shots at a recent event. I had this scenario a while back and I remember being told about the Screen Filter under Keyers > Blend > Screen in Edius 7.42.20 (hoping to update to 9.5 later this year). I've been editing for thirty years but don't use Keyers often. I have the original clip on track one and duplicated the clip on track 2. If I add the Screen filter to the top clip everything is a lot brighter. I can go back and adjust the level to whatever I want so that's not a problem. Neatvideo is not working even if I try it on both clips simultaneously or each one separately. That's with Neatvideo being the top filter in the information tab. So what is the Screen Filter actually doing? Any other suggestions or different filter ideas?

you can use the YUV Curve filter to raise levels

or in EDIUS8 or 9 you can simply drag the exposure slider

I usually use a YUV Curve but I found the Screen Filter interesting. Thanks Anton

The Screen filter in Edius is an analogue of the filter in Photoshop, and here is a good explanation of how that works:

underexposed clips is way better than overexposed.
best to use the YUV Curve adjust shadows, mids etc...

the screen filter... never used it for that function. and I am pretty sure its not used for correcting clips.

There are enough situation were you can use the screen filter to help with underexposed clips.
If you do a search you will see good explanations how to do this.

I'm pretty sure I saw a tutorial about quite a while ago. I don't have a lot of experience with it but it seems to work well (when used with additional tweaks). Are you suggesting doing a search on this forum or google? I started looking here but didn't find much. Thanks.

Here is an old thread about the Screen keyer method:

https://forum.grassvalley.com/forum/...ead.php?t=1446

Note that this also works with nested sequences. If you need to brighten the result of a sequence with lots of effects and edits, just create a new sequence, and drop the sequence you want to brighten onto two video tracks in the new sequence, and add the Screen keyer between them.

Conversely, you can create a sequence called "Brightened", add a clip to be brightened to two video tracks, add the keyer, and then use "Brightened" as a source in your main editing sequence.
