Text Disappearing For One Frame

Hi Forum.

I have an issue with text disappearing for one frame, my text appears normal on the timeline and as I scroll through my composition, I notice that It vanishes for one frame then reappears as normal. When I do a preview it makes an awful flickering. I am tracking the 3D stroke above and have alpha Matte. but when I turn Alpha Matte off and set it to normal my text appears without vanishing for that particular problematic frame, ( of course I lose the 3D stroke effects though). What can be causing this issue?

Thank you.

    Your screenshots don't tell us much. The top layer is being used as an alpha track matte for the bottom layer, frame 10 and 12 seem to show the text layer, we can't see what is happening at frame 11. What are the modified properties of both layers? I can see that the bottom layer is a png file and it is scaled to 400% so it's probably pretty soft. You should never scale a stationary layer over about 120% unless it is a vector image like a shape layer, a text layer or an Illustrator file. The anchor point tells me that the PNG is probably 1920 wide and 920 high so it is not the same size as the comp. The position property could mean anything because 1321.5 for X and 192 put it outside and above a standard HD comp and barely inside and at the top of a 4K comp. I assume that the top layer contains some kind of animated paths because it is being used as a track matte for the bottom layer. I also assume that you are using Trapode 3D stroke in the Paths layer because of the reference in the post. This is probably a pretty good assumption since the layer is not 3D, but we have absolutely no idea what you are trying to do.

    I guess that is enough about what I don't know or can figure out about your project. The most likely cause of some random odd images is a cache error. The easiest way to clear that error is to use Edit>Purge>All Memory and Disk Cache menu. If you have already done that then we need to see the modified properties of your layers. Just press the U key twice and PrintScreen and paste. It would also help if we knew the comp specs and what you are trying to do. If you want to troubleshoot the problem then duplicate that comp in the timeline, open the duplicate, reveal all modified properties by pressing the U key twice and then start adjusting some of the parameters or rest them to see what is causing the problem.

    Thanks for the reply, here's some more information.

    ( I managed somehow to solve the issue by closing AE, then turning on and off the layers, moving the 3D stroke keyframes around and it eliminated the vanishing frame.) But for learning sake, I'd like to know more about this issue, what can cause it.

    Frame 10 and 12 are showing the text layer, and at frame 11, that's where the text is vanishing just one frame.

    Here is a screenshot of the modified properties. The Paths layer has trapcode 3D stroke applied to it.
    The bottom layer is alpha Matting the Paths above it. As seen the vanishing frame (Red Rectangle) is way later to where the properties are modified with the 3D stroke.

    Could there be a possibility because the file with placed in my external hard drive it was causing an issue with RAM, making

    it flash?

    Thank you.

    Yep, having the same issue....

    Its just a simple stroke of an ellispe, two key frames with an easy easy curve applied....simple basic stuff

    tried empting the cache, tweaking the keyframes, changing the 'first vertex'

    Running latest AE + latest version of 3D stroke....

    Any suggestions please
