Video filter help file

I noticed that a particular piece of video was a bit dark. From basic information I was able to select the video filter option. There I found the Brightness and Contrast Filter so I dragged that on to my dark clip. I played a round with the settings to adjust the brightness. I played the resultant clip and it seemed to get brighter as the clip played. I thought this was a "feature" that wouldnt appear on the final video. Having burnt the DVD I noticed that it did get brighter as the clip played. I then went back to the clip and the attribute tab of the filter and to the left of the customise filter i noticed a drop down box. On selecting this drop down box I finally realised that there was more than one brightness filter. The default one I selected was self animated as getting brighter so I had that "wow" feeling of working out why my clip was getting brighter. I then selected the one on the top right and it didnt get brighter as its self animation. All is well. What I then wondered was where are the help files on each of these filters and subfilter types as to what exactly they do and which one you would need when? I feel a depressing answer coming that, like me, there is no answer until you go through the hard struggle I went through and try each filter and waste precious life moments due to lack of documentation. Can anyone prove me wrong?

Hi David

I think you know what¡¦s coming.

Cannot prove you wrong I am afraid.

What I would suggest is to try the Auto Exposure and Auto Level filters
One at a time or together.

Although the Customize option is available, there is little you can do to change the effects.

Most of the video filters come with preset examples of how key framing works. You can use them "as is", modify them, or make your own.

From the VS10 manual: "Key frames are frames in a clip where you can specify a different attribute or behavior for your video filter. This gives you the flexibility to determine how your video filter will look like at any point in a clip."

See page 72 for the chapter on Key Frames. (A link to the pdf manual is below.)

Thanks all. Is this auto exposure and auto level like "smart fix" in photoshop? IOW if i feel a clip is too dark or too bright or miscoloured, should i throw on both these filters just to see if it gets better?
