track matte won’t render in Premier Pro CS6

[Tim Kolb]

Would Premiere Pro “preview” render it?

Yes, I too have experienced this although my situation was much more complex.

I wanted to reveal a Photoshop layer of text using a soft wipe, over a video background. The Mac side of Pr does not have a soft edge wipe transition (pretty basic stuff, one would think) so I set up a soft edge gradient still image, from black to white, and tried to use it as a track matte.

My machine would not even show me a preview if I parked the playhead over the track matte portion. I had to move the Photoshop clip and the gradient to an empty portion of my sequence (i.e. no background video) before it would even show me the track matte, and no, it would not render for me.

After several attempts/modifications I finally gave up and went with a dissolve.

I had a slightly different issue with track matte effect.

On Video 1 a video clip. On Video 2 I had a Rampant Design Animated Style Matte which could be used as an Alpha or Luminance matte.
Then I would assign the Track Matte effect to the clip on Video 1 and set the controls to look at Video 2 It looked wonderful.

But, when I would do a Preview Render (which was necessary for other reasons) the result show a very screwed up image where the matte was being badly interpreted for the first few seconds the image played.

What fixed it was to move both clips UP one video track AND on Video 1 and a black slug. When rendered, the track matte now was displayed correctly .

Images of the momentary reversal effects that corrected after playing for a few seconds.

Can you guys fill in some more detail on what you’re doing?

I can’t seem to create a problem on my system.

Is there a particular type of document you’re using for a matte? Any particular effect that you’re using with the key?

I can even make the matte on two-key source on track one situation that Tom was referring to work…though since you usually key over something else, I can’t visualize the purpose of doing that.

LOL! Tim, I dont think I can explain it any better then I did in my post, which does a pretty detailed breakdown of what is where. With pictures even 😀

🙂 You didn’t say what sort of a clip the matte was…since it had an alpha channel, there is a smaller set of options, but still, it could be a number of filetypes…and you didn’t mention what sort of file the video was either…

I’m tryin’ to repro your bug here man! 🙂

(…but once you make the matte key with the source on V1 and the matte on V2, what is “outside” the matte if there isn’t anything below it? Is it just empty black?)

Sorry man . I thought I had been thorough.Actually the problem has been solved, if you reread my earlier post.

1, Video 1 has video clip (Photo-JPEG QT movie) with Track Matte effect (set to either Luminosity or Alpha, both had issues when it was rendered).

2. Video 2 has Rampant Design Style matte. Its a b&w animated QT matte that cuts the hole ( either with luminosity or alpha channel) and reveals Video 1 media.

So you get video revealed with animated mattes over black.

It worked great until I had to render it. Then it looked like the images I posted….wrong.

The solution was to move the clips up a track and put a black slug on track one. That allowed me to render the effect without it getting screwed up.

Yeah, I gotcha… I don’t use empty timeline as black, I don’t know how I got into that habit, but I have.

At any rate, I don’t seem to run into issues with the track matte key here, so I’m trying to see what file types the posters in the thread are using…and which effects/blurs, etc.

There are two possible reasons

1 – you misspelled Premiere Pro and it took offense. 😉
