Jul 22, 2016 4:48 AM in response to alicemeadeby QuickTimeKirk,QuickTime Player 7 Pro movies can have up to 99 tracks. Each track can have it's own position, layer, transparency and mask.
A mask is just a black and white image sized to cover the dimensions of your video. It is usually a shape that blocks some of the video.
The Pro version of QuickTime is no longer sold by Apple.

Jul 22, 2016 5:30 AM in response to QuickTimeKirkby alicemeade,Thanks. I have created a mask with black and white areas. I have tried going to Visual Settings and adding this PNG file to the Mask. I have tried opening and dragging the file into this. But it does not mask my video at all. What am I doing wrong?

Jul 22, 2016 7:44 AM in response to QuickTimeKirkby alicemeade,Yes, I do this. I choose the file and then close the Properties window. Nothing changes in the view of the movie. I saw in one Youtube video something about getting to choose where the mask appears in your movie. I don't know how to do this.

Jul 22, 2016 8:16 AM in response to alicemeadeby QuickTimeKirk,Your mask track must match the dimensions of the video track it covers. Take a look at the screenshot I posted above:
You can scale your video track but not the mask it covers. The offset values show how many pixels from the upper left corner your other video tracks might be. The layer values move multiple tracks to the foreground and lower number values are further to the "top". The transparency options are also for multiple video track movies.
If your video only has a single video track your mask must be the same dimension.

Jul 22, 2016 8:51 AM in response to alicemeadeby QuickTimeKirk,I see 3 colors in your mask track. The word Hello appears to be gray. Is this correct?
You have a very small area that shows as white and that would be where your underlaying video track would play.
Click the Invert button and it will swap the black and white areas. Does that work for you?

Jul 22, 2016 9:03 AM in response to QuickTimeKirkby alicemeade,The word Hello is in Red in the PNG file. I wanted the white rectangle to be the "mask" and block out that portion of the video. I tried Inverting. When I did this, it resized my movie and cut off about 1/3 of the left side. I don't see the word "Hello" anywhere. Nothing is "masked". I saved the movie as Temp. When I went to Finder and launched the movie Temp, it was the original movie. Nothing had changed!

Jul 22, 2016 9:07 AM in response to alicemeadeby QuickTimeKirk,A mask track can only be black and white.
When you inverted the .png file it resized because its dimension doesn't match the dimension of the video track it covers.
Resize your mask .png file and make it black and white only.

Jul 22, 2016 9:09 AM in response to alicemeadeby alicemeade,Actually, that is not true. When I double click it launches in QuickTime Player 10.4. I did all of this editing in QuickTime Player 7. If I open the movie in QuickTime Player 7, then the cut off pieces are still cut off. But the word Hello does not appear anywhere. Also, I don't know why it cropped my movie and did not Mask it. Could this be that the Mask was smaller than the original Video. Also, how would this appear on YouTube?

Jul 22, 2016 9:16 AM in response to alicemeadeby QuickTimeKirk,YouTube may not be able to play your file until it is "converted" by QuickTime X.
If QuickTime Player 7 (the authoring app) can't display your file as you want then your .png file is the wrong dimension. The word Hello will not display because it not a part of a mask track that QuickTime understands. They can only be black and white (hide or show the underlying video track).

Jul 22, 2016 9:23 AM in response to alicemeadeby QuickTimeKirk,Did you size the dimension of the mask track to match that found in your video track?
