Mocha AE 2019 Plugin - tracking fail

Hi!

I'm trying to track a footage in the new Mocha AE 2019 plugin. Everything seems fine until i try to import the track motion into After Effects.

When you hit the "Create Track Data" button, it was supposed to import the keyframes from mocha, into the layer you're trying to apply to, but nothing happens with my composition. I can apply an mask following the path i did in mocha, but the tracking just doesn't work.

What can i be doing wrong?

Hi, Im having the same exact problem and mine is not as simple as clicking the gear icon. I have done this several times and nothing works. I am almost positive that this is a glitch as I have spent 3 hours now watching tutorials and I am FURIOUS!

So here are screen shots + steps.

1. Tracked my screen in mocha using spline tool.

2. Saved the tracking data, closed mocha.

3. Open AE, I see mocha tracking data in the original footage

4. I click "Create Tracking Data", and I make sure the gear box is selected.

5. Next I configure my settings, setting it up so that the tracking data is sent to the image im using to replace the screen with. And the replacement screen layer is selected under the output (the replacement screen layer as been pre comped and fit to frame size)

6. I press, "Apply Export" then I rip my hair out because the key frame tracking data still is not inserted. WHAT THE HELL!!!

malcolmg83716917malcolmg83716917I had the same problem you did. Where you only get keyframes for the first frame. You can see mocha is tracking your object but it just isn't applying the keyframes to the rest of the clip. My clip was speed reversed in Premiere Pro. Once I brought it into After Effects I un reversed the speed. That messed everything up. Once I deleted the speed reverse in PPro and brought it back into After Effects everything worked. I noticed you are tracking a comp. I wonder if you have to track just the clip. Give that a go and let us know if it worked.

I just spent a couple hours trying to stabilize a clip with Mocha AE CC.  Turns out that it won't work if you have time reversed a layer at any point before tracking, even if you un-reverse if before doing so.  I have to grab a fresh instance of the clip from my project panel.  Then it worked fine.

    Yo brother! I found the answer!
    When you export the tracking data, a new window open, you have to select the layer with the data, and CHECK the little engine at the left side of the box. That´s the secret!
    I almost spend 2 days in this shit! Its simpler than we thought!

    Greetings!

      This is the answer! When you select the layer in the pop-up window you need to hit the blank space to the left of the layer to activate it ( make a gear icon appear), then press ok and it will behave as expected and populate the pins with tracking data keyframes.

      It appears to be a design flaw, not human error, as finding that box was not intuitive at all. I'd like to request a ghosted gear if not activated in the next update, or a more intuitive menu in that pop-up.

      That being said, I'm loving the new simplified mocha setup that is fully integrated into AE rather than the earlier setup.

      Thank you Daniel for sharing this info! You saved me an unknown amount of frustration.

      Once you have selected the tracker in the Create Track Data button, you must use the Export Option and Layer Export to options in order to use the tracked data in any of your layers and the click the Apply Export button.

      Thanks, Jose Panadero, but i might have not being so clear.

      I saw this Boris FX video and when she creates "Track Data", the After Effects automatically imports the keyframes from Mocha, and then you can apply it in other layer to attach into your footage. But when i try to do the same, i have no single keyframe from the tracking and, even if i try to "Apply Export", my target would hold stand still, cause there's no parameters for it to follows.

      This might be a strange error or i'm doing something wrong in the tracking process, but i've made no different thing from the older versions...

        It's user error, not a bug. Mocha AE caught me the first time too. You have to make sure that you select the layer you have tracked and that the layer is active (gear is showing) before any data is copied.
