After Efects Error: overflow converting ratio denominators.(17 :;18)

Hello, I am experiencing a serious problem with after effects.

It started when I right clicked a clip in my premiere pro timeline and chose "replace with after effects composition."  Upon moving the clip into my already open after effects project, the wrong still frame opened up in the comp viewer, followed by this error: After Effects Error: overflow converting ratio denominators.(17 :;18).  Clicking OK does nothing, and even after closing after effects and restarting the computer, upon opening my project, I simply get this error which will not go away, and as long as it is open, I can do nothing else with after effects.  I cannot just create a new project as several other comps are contained within this specific project, and because of this error I now have no access to them.  What can I do to correct this?

    There is another FIX if nothing helps.

     

    Create a NEW Project and Import the old Project. Open the File, it should work. But it can occour again. You also can try to reload an older Autosave. Its a bug...

    In project, right click the video and click 'Inspect Footage'. Then, click 'Main'. Go to your fps (frames per second) and round it up (or down) to a whole number. That's it: )

      Hi, probably the frames of your clips does not have the same frames per second. That is why is showing the error. Go to you file ] right click + details and check how many frames Per Second is this file recorded. Then sync you composition settings to the same Frame rate. And voila!!! Hope this may help you.

      This is a very old thread, but I ran into this problem today with the latest Premiere & After Effects. To solve the problem what I did was right-click my footage in Premiere that I wanted to edit in After Effects and click Render & Replace, choose your desired settings and then it will do its conversion. After that replace with after-effects comp and it got rid of my problem.

        What I found that works for me when this happens is exporting the clip from Premier that I want to use in AE.

          Hi!

          I had the same problem right now. Import the files with Caps Lock allows me interpret my footages. The old frame rate of my files was 15,0015 FPS. I just changed to 15. Problem solved.

          Youre missing a video codec or it got corrupt with an update.  Try uninstalling QuickTime, Divix, etc and reinstalling them one by one.  That should fix the problem. 

          Also if special video software is required to run the footage you can also try pre converting the footage before applying any effects to it.

          Just in case anyone is having this error and none of these solutions are relevant.

          I just tried to open a project passed on to me today and go the error, I realised it is caused by a peice of footage exported from Final Cut Pro as a 'reference movie' instead of 'self contained' (an easy way to spot this kind of file is if it is a suspiciously small file -like a 30 second HD clip that is less than 1MB). I'm assuming this wasn't a problem for the person who gave me the file as After Effects was able to access the render files that the reference movie were pointing to on their own computer, but now obviously After Effects can't find the footage the file is referencing now because it's not on my system.

          The problem can be solved by deleting the footage from the composition, which can be difficult with the error popping up constantly.

          Alternatively, if the footage is really important to the composition, just export it again from FCP as a self contained movie and replace the footage file at it's source. Close and re-open AE and it will link to the new working file.

          Hi Justin,

          See if this will work: Leave the CAPS on before starting the program, hopefully that will allow you to have access (without the overflow error which is very frustrating)… if you do, then you probably know what to do next, but if not: change the frame rate by right clicking on the video file and clicking on "Interpret Footage" and then click on "Main...", then under "Frame Rate" select the "Conform to frame rate" and try to change the frame rate to the closest round number as the original frame rate. (If the original one is 30.05 change it to 30 and see if that works).

          Let me know if that works.

            Justin,Has anybody figure out how to properly resolve this issue? My above description worked for me but the issue I have is that it will cut the length of the video when the frame rate is changed (despite what number you change it to).

            I can't believe that this issue is unresolved to date since researching it has been discussed for over 4 years now at different sites. I couldn’t find any solutions online.

            This error either indicates a problem with the source footage or a specific effect. It's simply a math error somewhere deep in the fabric of the project, e.g. by misinterpreting footage sizes. In order to open the project in AE without the warning cropping up immediately, you could try to open it with capslock, so it doesn't attempt to render anything. Then you could at least inspect the footage in the project panel by selecting it. If you see something odd there, this might get you closer to finding the cause of the problems...
