To put right a very underexposed clip?

[Ulisse]

Hi, I use Edoius 7. I have a precious but very underexposed clip. I need to put right it. Some years ago I used a trick. I created another clip on the same underexposed clip (2 clips of the same clip), then I added a filter on the second clip but I don't remember what filter and the process. I only remember I solved the underexposed problem. Do you remember this trick? Or do you know how can I solve my problem?
Thanks

Perhaps: Effect > Keyers > Blend > Screen onto the upper clip.

My Edius is in italian language. Your image was OK. Now I have just found that filter even if it doesn't have solved my problem but a little bit only.
Thanks again one.

Can you attach an (single) image of the dark clip.
I would try if YUV-curves can solve your problem.

This is the image of my original dark clip.
Thanks

Matt Scott http://mattscottvisuals.com/color/ has some good tutorials and you can follow how to create a mask of the high luminance area so that you can use the YUV filter to bring up the under exposed area. You can do this on a copy of the clip in a track above so that the combined will both show the corrected face as well as the high luminance background.

Hi Ulisse:
Your image is a challenge. I tried some procedures to enhance the person, the best at the time I have attached together with your original (when filming this person it would have been much better to focus the exposure onto the face of the women - and ignore the sky).
For I dont know if you find my result "better" than the original (there was some steps to get it) I show both images here; if you think that my result is practical for you to use it in your film then I will list the steps how to get it. OK?

This was done with luma key mask, copied to two tracks above with YUV and color boost. Very quick so could be improved with some work.

jpg version. You could do better with the source video than modifying a jpg.

How about this quick 'n dirty one ?

Chrominance key with inside filter combining YUV curve + 3CC + Color balance.

The process generates some ringing. It may be useful to soften the image on key boundaries.

That looks good!

Dear kpot,
unfortunately your output is not better than mine and I'm thinking to give up.
Thanks for your availability.

Lotn,
your output look good. But may be it is too much hard for me to find those steps. I am not an expert guy like you. ;)
Thanks
