Megaplate doesn't make a megaplate

Hi folks!

I’m sure I’m missing something obvious but I’ve followed the tutorials and read the manual and I just can’t get the megaplate function to work. I set everything up–track, extend the box to make sure my plate is defined, the whole works as far as I can tell. When I press the render button the render bar shows up in the upper right, shows me the frame number matching the frame I’m parked on, maybe progresses a 10th of the way in one brief jump after ten seconds of waiting, then is done with no changes on screen.

I tried making the megaplate area and length shorter and changing the step number and got pretty much the same.

Any suggestions?

Can you send me a screenshot? And is your shape unlinked from the track or linked to it?

I’ve tried it both unlinked and linked. I’ve fiddled with the numbers in the search range too.

You might be asking it to do too much and the math is stalling out. Try using only a hundred frames before and after, 39,864 frames at a time is a big ask on processing.

Try changing your first frame to 39113 (i.e your start frame) and the before/after frames to 750 (i.e the length of the section you care about).
As Mary says, right now you are referencing the entire shot.

Also turn on Autostep.

Getting the same deal after setting the frames as per your instructions. I had this problem with short clips before but those are all strict NDAs and I wasn’t allowed to share.

I tried setting it to 16 and 32 bit. I exported the scene and made a new mov out of it so it wouldn’t be part of a huge clip. I tried setting the First Frame and Last Frame so it was only doing ten frames with 0 before and after.

No progress.

Sorry to hear you are having problems. If you can not share the project, perhaps you can reach out to @maryp or @martinb for a quick screen share to see what is going on.

Happy to remote in and see if we can troubleshoot. You can email me at and we can set up a time and I can get your contact information.

Hi everyone :slight_smile:

I have the same or similar problem.
I followed the tutorial step by step, but when I click render in the MegaplatesTab I always get a frame thats not Mega at all. It’s just the actual frame where the playhead is located. A frame of the actual size of the footage 2048 x 1080. Autoscale or a manual value for a bigger plate makes no difference.

Has this been resolved in the meantime?
I tried all you suggested in this thread, but still no success. In Aftereffects and Standalone Version 7.0.4.



Can you share a screenshot Or Video recording of your Mocha project? Megaplates are working as expected in current Mocha Pro versions, so we need more details to help.

After tracking, have you extended the Spline layer to be a much larger canvas? Have you tried rendering on various frames?

I repeated the whole proces 3 times with the tutorial open and playing. Still no success. The only difference in my case is, that there is not foreground to be removed. A simple pan that I can easily stitch together by hand from 3 plates, but I would like to have Megaplates working in case I come across a more complex shot.
I can do a screencapture of the process but cannot post it here because it’s my clients footage.

What was the solution to the problem of the original question? Maybe it’s the same here.

I did a screencapture of the whole (not working) process. I hope I just miss a simple action. :slight_smile:

Where can I send that to? As I mentiones above, I cannot post the footage public here.



You can send it to and I will take a look.

Was there a solution ever found to this problem? I just ran into the exact issue described above and none of the trouble shooting steps fixed my problem-

I’ll add that if I hit "create, it’ll export a frame the size of my tracking shape but ONLY image is the reference frame from the middle of the clip.

windows 10; afx plugin 8.0.3;

Thanks for your time.

There was a fix but I don’t remember what it was! I got on a zoom chat with Mary and she figured it out.

I… also do not remember the solution but I am happy to take a look again.

I could really use the help! I’ve tried all the troubleshooting I can find/think of and still I can’t get the plate to render, and on top of that - the remove module won’t show me what’s being rendered until I’ve exited the app and turn on the check box in the effects controls of After Effects.

Okay- so I tried one last thing and it worked.

So for anyone else who may run into this in the future- I turned off “Use GPU Processing”. I was able to render out a megaplate. The ‘good’ news is that I was able to do all the tracking with gpu on, but then had to turn it off for the render, so at least it’s not completely slow!

Can you send me the footage and project file to MaryP at I’ll take a look.
