Color Correction

Sephirex · Post by **Sephirex** » Mon Nov 26, 2007 6:28 pm

Everytime I use the color correction I use the simulated settings(sunny, cloudy, overcast, fluorecent etc.) and whenever I switch off the clip the settings turn off. How do make them stay?

What do you mean by 'switch off the clip'? Have you made it, or included it in, a project, then saved the project after you have applied the filter but before you 'switched it off'??

I mean that whenever I do something else other than the clip, weather it be publishing it, saving it, putting it on the timeline, doing another clip, the Sunny setting I'm using goes away. As soon as I click something other than the clip or the color correction settings, the Sunny setting goes away, no matter how many times I put it back on.

I'm not totally sure I understand the problem you describe but are you aware that any correction done on the timeline will be deleted if you remove the clip from the timeline? To make your correction permanent, make changes to the thumbnail in the library.

That's how I started out in the first place, I did it from the library. Then when that didn't work I did it from the timeline. Neither of them work!

Now I see what you mean as I am having the same problem. It will be interesting to see if anyone has a solution. In the interim, I have found that after you make your correction to the thumbnail in the library you can check the "Auto Tone Adjustment", then uncheck the "Auto Tone Adjustment" and the changes seem to be saved. Give it a try!

I'm not sure I fully understand what the two of you are on about. It doesn't matter what you do to a clip when it is on the time line, the changes are not saved with that clip. That is the beauty of NLE, whatever you do will not affect the source clip.

If you save the project, the project file will contain all the different actions you did with that clip. You can also preview it and all is there. If you then open another project and insert that very same clip on the time line, none of the actions you took in another project will have been retained by your clip. It is still a virgin clip.

Only the project file where you saved these actions will be able to recover all. If you want your clip to be modified by your actions, you need to go to "Share" >"Create video file" which will render a new clip, containing your modifications.

The thumb nail in your library is only a cached representation of your clip. You need to force the explorer program to re-create the thumb nail in order for it to show any changes. If the underlying clip had changed, the thumb nail would still show the originally set image. It is not representative of what is in your clip really.

A little icon should appear on the clip on the timeline when a filter has been applied to the clip.

I should correct myself now cause I'm not sure if this applies to colour adjustments

I agree. I have been studying an online tutorial at another site and their instructions are the same.

Your explanation makes sense, but in trying to help Sephirex I made a drastic color correction to one if the clips in my library, exited VS and when I returned to the program the correction was still applied to the clip. I learned this trick from the same online tutorial mentioned above. None the less, after pondering your explanation I am now uncertain about the validity of my experiment.

When you exited VS, you would have been asked whether you wanted to Save or not. You probably said yes. In other words, you saved a project with the colour change noted in the project .vsp file.

I also have never done any of this and only quote from memory and what makes sense to me. Since source clips are not affected by any editing, I doubt that your findings are correct.

I would happily stand corrected if someone can prove the opposite to be true.

I tried it again to confirm that it worked as previously described. I opened VS, made noticeable color corrections to a clip in my library and closed the program, all without receiving any prompts to save my changes. When I reopened VS, the clip still displayed with the modifications I had made.

As I stated before, I am new to this so I'm not totally convinced that my findings are valid, but it has been an interesting experiment none the less.

Ok I ran some quick tests on this Clip in Library issue..

I found like SoldonParadise suggested, if you apply a color correction to a clip in the library,

VS will close without prompting you to save the changes.
Reopening VS and selecting that clip the changes are still applied.
The color correction is not applied to the actual video clip.

To determine if the color correction is applied to that actual video clip, after applying, I navigated to where the clip is stored on my PC, then played the clip in WMP. No alteration was found.

So VS must save those changes as instructions, just like saving the location of the clips in the library, even though it does not ask if you want to save them. However does not apply it to the real video clip(s).
