Data driven animations for overlay on video - mgJSON?

April 2, 2019, 1:38 pm
$

I'm looking to add an overlay animation on videos that include data like speed, g-forces, other sensor data, etc.

An example of this is https://www.facebook.com/watch/?v=324625525065975

 

So I have sensor data in any format I require with timestamps but I need this to drive the animation data - shape position, rotation, etc. dynamically.

 

From looking around this (Work with Data-driven animation) on the surface looks to be very exciting. From what I can see though, just standard json or csv would just be used to render static data, without altering based on time. There's talk of mgJSON files which sound like it would do the job but I've yet to find any information on either how to build that file format or even how to export an example from AE and alter that example with real data.

 

Any input or help would be greatly appreciated.

Unknown BIB Error. Unknown Bravo Error, BRV, 0 (83 :: 3)

I'm trying to render a comp but I get about 4 seconds in and the render Crashes with this error message.

 

Capture.PNG

 

 

It's crashing on a layer that is a precomp with some expressions inside of the precomp and on the precomped layer.  It's a head, it's mouth is moving so I'm using a Duik Bassel connector expression to do that.  This is a head layer is part of a full body rig.

 

The project contains three characters rigged identically (with totally different names, etc.) so I'm not sure why it's crashing on this particular layer, as there two other rigs with same set up and expressions where it's not crashing. 

 

I'd love some help with this.  I've redone the rigging and expresions on the head layer, but that doesn't help, I read somewhere in the forms about this potentially being an issue with fonts, so I've uninstalled and reinstalled the ones I need the project, but Ithat's not working. Any other suggestions?

After Effects 2019 crashes when opening Windows Explorer

HI,

 

I've searched the forum but the solutions I found didn't fix my issue.

 

Latest AE and Windows 10 builds. The computer is a Gigabyte Aero 15x laptop.

 

When AE launches WIndows Explorer to save a project or to import some footage it freezes and then after a few seconds just crashes. It started as a random issue but now it's pretty consistent, to the point when I can't use the software.

 

I don't have Microsoft Office nor OneCloud installed on this machine.

I can't find any log inside the AE logs folder. I've tried uninstalling and reinstalling the program. I'm not sure how to use the Windows Event Viewer but at a first look I can't see anything related to AE.

 

This is a software that I pay and with which I need to work on a daily basis to make a living. Please help.

 

Thank you.

"Disable Refresh" menu option?

Hi all,

 

My MacBook Pro has the dreaded butterfly keyboard problem. My caps lock key has stopped working. I'd like to "disable refresh" in AE on some heavy comps while I work but I can't seem to find it as a menu option, and caps lock doesn't work.

 

How can I toggle "disable refresh" in the comp window without the caps lock key? Is it under a menu and I'm just missing it?

Immersive Video: Scale Sphere?

I'm working on an immersive video project, and I'm wondering if there is a way to scale the sphere? I've used "VR Rotate Sphere" to rotate the footage, but I haven't seen a way to make the sphere bigger.

 

The problem I'm trying to solve is the video looks like it is too close to the camera. Objects appear too big and the viewpoint of the camera is too tall. I've tried moving the footage on the Y axis which helps with the height issue, but things still look too big. I was hoping that I could enlarge the sphere slightly to make the video appear farther from the camera.

 

Or is there a different way to do this?

Weird gray layer above all layers after opening my project. FilmDamage_1.mp4

Hello to all After-Effects Pros,

 

I just opened my project as usual which never had any problem. It was already a finished project from me, I wanted to make some small changes and after openening I had this strange grey pixel layer above all layers"!! It runs through the whole timeline, but I can´t find the problem. It only says in the left upper corner "FilmDamage_1.mp4". That´s so strange I never had such a problem. And I don´t see where this problem should have come from suddenly....

 

Someone knows the answer?

Why won't the tracker analyze anything when I start it?

I'm trying to track something over my face but the motion tracker seems to have bit the dust. I'm fairly certain I have all of the settings correct. I tried transcoding the footage, since I read that certain codecs weren't supported, but despite trying Cineform and then uncompressed .MOV files, I'm still not having any luck. To clarify the actual issue: When I click the "analyze" buttons (one frame back/forward, track back/forward) they react and switch to the "stop" buttons, but no motion actually happens anywhere, and the track point doesn't move.

Any help on this would be appreciated. Thanks!

Out of memory crash

Greetings,
since the latest update, i get more and more, after a few minutes working, a memory error, followed by a crash. Most of the time it is not possible anymore to load the saved file again. It ends also in a crash. The error does not appear all the time. But it seems it has nothing to do with the actual project size.

 

I use to work on a fresh started system and no other applications loaded.

I have 24 GB memory installed and i let AE use up to 18 GB.
I use this setup for years now and it was never a problem.

 

 

Cache is set to 50 GB on a brand new and fast SSD. The solutions provided here in the forum seem not to work in my case.
WIN 7 / AE CC 2018

 

Any suggestions?

Simple renders fail/out of memory

November 20, 2018, 3:48 pm

Hello AE community,

 

I've been having this problem with memory that I have never had before in AE. I made a project that's about 2 minutes long, and all it contains is audio and icons moving across the screen. Probably the most intense thing I have going on in this project is motion blur. I keep getting a number of errors such as the "unspecified drawing error", "After Effects out of memory", and my renders consistently fail. I've tried rendering in Media Encoder and my renders still fail. Sometimes AE will crash when doing previews even when I delete memory and disk cache frequently. My RAM will spike to 100% usage (what seems like) randomly. I'm running 16 gigs of RAM and my disk drives have plenty of space on them, so I don't see how AE is running out of memory on such a simple project. This issue happens across the board on several of my projects that are similar in structure and concept.

 

Is it a graphics card issue? Because after doing some research trying to figure this problem out I found that my graphics card isn't compatible with AE CC. Any guidance in this subject would be greatly appreciated.

 

(And yes, I have updated all of my drives)

After Effects: Out of memory.

February 18, 2019, 8:56 pm

I cannot for the life of me figure this one out, Google has not shown me any answers. I am editing some masks of an AI file in After Effects and I will randomly get the following error:

 

"After Effects: Out of memory. (5059K requested)
(23::40)"

 

Forcing me to the Task Manager and end AE's process to close it all down and restart the program.

 

This will happen when doing ANYTHING really, the content or what task I am performing does not matter, this will happen at random anytime I am working in AE. Now, everything online says people with similar errors might need more RAM. I do not see that being the case here since I have 32 GB in this PC. I allocate 26 GB of that RAM to Adobe products, so how it ever runs out of memory is beyond me.

 

I will admit that I have not attempted to reinstall or anything yet due to time constraints, but it is at a point now that is almost impossible to work with. Please let me know what is going on here and what solutions might help.

 

Thanks!

After Effects Error: Keylight out of memory. (4) ( 25 :: 241)

December 5, 2016, 12:14 pm

Hey there, this is very frustrating.  I don't know of this is because of the update to After Effects CC 2017 or what...

 

I have been working for a client on a series of 'How To' videos shot in front of a green screen for the past year.  The files are all h.264 (not 422, which I wish they were), they have all been shot exactly the same, and there is nothing different except that I now have updated to After Effects 2017.  I use Keylight for my green screen needs.

 

Every once in awhile (frequency is random) this error shows up: 'After Effects Error: Keylight out of memory. (4) ( 25 :: 241)'

 

Now, thankfully, it never crashes the program.  I hit 'okay'... and then move on, until it happens again.  Same thing: hit okay and move on.  No crash. 

 

It's so frequent now that I am now just used to hitting the space bar twice to move on and it's become a routine.  Unfortunately, it's hard to get into a flow because of it and cannot find any updated information on how to get it to go away.

 

Again, I'm thankful this is only an annoying inconvenience, and not a problem....but any advice would be wonderful.  Or is this just an AE CC 2017 bug?  Thank you!

 

My computer specs:

MacBook Pro (Retina, 15-inch, Late 2013)

Processor : 2.6 Ghz Intel Core i7

Memory: 16GB 1600 MHz DDR3

Graphics : NVIDIA GeForce GT 750M 2048 MB

 

Footage is 1920 x 1080p 29.97 frames h.264

AE CC 2018 ridiculously slow

Seriously, what is wrong with AE CC 2018!?

I'm on an absolute beast of a workstation, a HP Z840 with 128 GB RAM, dual Titan X:s and so forth, but I can't even preview a simple text animation!

It takes forever to preview, and playback tops out at about 10 fps... I've got nothing in the timeline but animated text, no other graphics, no video, nothing.

And it's not only the preview that's messed up, the entire interface is laggy, when I move the cursor in the timeline sometimes it takes like a second for it to catch up.

Everything I try to do, import a file, keyframe an object, add an effect to something, and so on, takes forever.

I've done restarts, checked nvidia drivers, purged all memory and disk cache, cleaned database an cache, everything you could ever think of, but it's still painfully slow.

I never had these problems in cc 2017, it ran like a dream.

 

I'm at a point where it is virtually imposible to work, and it's making me a bit frustrated to say the least.

 

Don't tell me I have to downgrade to be able to work, that would just be, well, silly.

Why on earth would anybody release a version this unstable?

What is the best workflow between Premiere Pro and AE for these kind of text-based videos?

I am working on creating a bunch of social media news videos which are similar to the formats that Now This and Brut follow. Here are a couple of example links:

 

Congress Pledges Minimum Income For Poor - YouTube

 

Heroic Boy Gets Citizenship for Saving 50 Kids in Bus Attack | NowThis - YouTube

 

What is the best workflow I could follow? I would need Premiere Pro to assemble the footage but I would need After Effects, too, because it has way more options when it comes to animating text, and creating graphics like arrows, etc.

 

I am very confused about what the best way to work with the two is.

 

What do you guys suggest?

Hi.

 

I get the following error each time I try to save, or AE tries to auto-save my project.

 

It happens after I have imported stuff from Adobe XD using the Import -> After Effects function in XD and then saves the AE file.

 

After Effects error: crash occurred while invoking plug-in "AE-XD Integration".

 

Is there a fix for this issue?

 

I'm running Xd: 14.0.42.14 and AE: 16.0.1

Layer Control Output

Hi,

 

with the recent update 16.1 they added a new Expressions Editor which is great but it looks like the also updated some of the syntax again.

 

With the Layer Control it used to give a error when there was nothing selected. So I added a try catch statement to get an output when nothing was selected. This no longer works. When you select nothing there will be no error.

 

I use a text layer to ouput the content of the Layer Control. In the legacy engine it gave you  [OBJECTLAYER] but now it gives you the name of the selected layer. But with none selected it gives you an empty text layer. I tried to get the output with 0, false and "" but nothing works.

 

Does anybody know what the ouptut of a Layer Control set to None is now?

 

Kind regards

 

Christian

3D curves and surfaces mathematically defined

April 3, 2019, 1:40 am

Hi !


I  only have a 1 month experience in After Effects. I am working on a series of free Math videos for students (my students or any, kind enough to watch them.)

 

Here is my question :

 

How can I draw a mathematically defined curve in 3D ?  ( For instance, a curve would be defined with : x(t) = ... ; y(t) = ... , z(t) = ... )

 

I will have to draw lots of them, and sometimes in order to draw surfaces ... mathematically defined too. ... and animated as time will be a parameter in all these definitions.

 

( If I could use depth of field to enhance the 3d feeling ... it would be perfect.)

 

It does not seem obvious in After Effects ... which surprises me as it sounds like a pretty basic need for a (maybe toot much) math oriented guy like me.

 

I heard that some third party expensive plugins could help to do the job like Trapcode ( which is far from being free ) .

 

In fact the question is simple :

What must I learn, what must I buy ?

( ... and therefore what must I sell to afford the buy ...       )

 

THANKS !

Why does the Exposure effect behave differently in the latest version of AE?

I opened one of my previous projects and it looks different in the latest vesrion of AE (16.1.0, build 204).

 

The Exposure effect in the latest version gives a different result with the same exposure values as before. For example, in my project I have the Exposure effect with the Exposure value set to 3. If I open the project in the latest AE version it looks so much brighter. To get the same look in CC 2014, I have to set the Exposure value to 15 instead of 3.

 

Exposure Bug - Adobe Support.jpg

 

Does the Exposure effect broken in the latest AE version? Am I doing something wrong?

 

P.S. I see this inconsistent behavior in the 32-bit project.

Hey guys,

 

I'm trying to create a logo/intro for an animation. I've got a solid colour layer, and a logo jpeg (clipped to black/white) to use as my track matte.

 

When I set the jpeg to as a luma matte both the white and black areas are semi transparent, rather than white being completely opaque and black being totally transparent.

 

What am I doing wrong?
