I have some videos that are .mp4. They do not work when I try the track matte alpha feature.

1. Does anyone know how I can convert a video, so that it will work with this feature?

2. Also, it would not let me import a .mov file, is that something new or something I did wrong.

Thanks.

Track mattes work with mp4's . You have to understand how they work and how to apply them.

Troy Stein, A TechSmith Employee

Put together 5 video tutorials regarding tracks mattes, and how to use them.

Complete with exercise files. If you want to wrap your head around track mattes.

This is a great place to start.

 As far as .mov's go. A lot of mov's are not supported by Camtasia.

You could convert them in a program like handbrake.

Thank you for your time and response. I did watch the track matte explained video, before attempting. However, it didn't work with my .mp4. 

Since I wanted to use that particular video, I didn't know if there was a way to convert it. The Techsmith written tutorial (which includes a download) said it had to be an alpha channel.  I wanted to see if I could convert an already created video to that alpha channel, so that it would show.

Thanks.

In Windows Explorer, rt-click on the MP4 file name and select "properties". When the properties window opens click on the "Details" tab. Make sure the frame rate is compatible with Camtasia, and also check Audio 'bit rate' Video 'data rate' are listed (non blank). Finally, make sure it's not Content "protected".

I'm not sure I understand your intentions.
You could blow out the brightness and contrast of a video and use its Luminosity as a track matte.
A video itself will mask out other content 100% if used as a track matte applied with "Alpha".

@Ed Convey and @ Joe Morgan.  Thank you both.  I'm going to play around with those and see what I come up with again. Thank you.

Give this a watch. A lot is going to depend on your content, but you can definitely create transparency with an mp4 video.

@Brooks  thank you so much for the video. I got to see the use of the brightness & contrast. This has helped. 
I'll post my finished project.

Thanks for the tutorial

The QT MOV format is no longer included with a Windows installation due to its security problems.  You can still go to Apple and download it, but install only the codec (not the player).  Note that only the Apple DL version will work — not any substitute MOV programs (I wasted time years ago trying that).  If you need more details, post and I can respond; alternatively, you can search the boards for earlier answers to this question.
