Yeah I'm pretty sure my problem is in the recording. My last ditch effort is going to be to just frame by frame it and then make it forced 23.976fps or 24 or something and see if that at least gives me something. ///Greg Balint //Art Director / Motion Graphics Designer /321.514.4839 delRAZOR.com/ On Sat, Dec 21, 2019, 1:18 PM Rick Gerard wrote: > First, keyframes in After Effects are based on time not frames.

First, keyframes in After Effects are bas= ed on time not frames. You can change a comp frame rate from 15 to 60 and a= 3 second animation will still take 3 seconds and there will be not skipped= or duplicated frames in any of the animation. The only way you can end up = with duplicate, blended or skipped frames in an animation of any kind is to= open up the composition settings and set the comp to maintain frame rate w= hen nested or rendering and then nest the comp in a comp with a different f= rame rate.

The same goes for time remapping. Animate a t= ext layer going from left to right in 1 seconds, pre-compose, timeremap and= change the move to 10 seconds and NO frames will be duplicated, you will g= et smooth movement.

Now let=E2=80=99s address your= problem video. Changing the interpretation of the frame rate of the video = changes the timing. If timing is critical the frame rate of the video must = exactly match the frame rate used to snoot the video.=C2=A0

<= /div>
If you have a recording from a monitor or video feed that is at 3= 0, but the original footage is at 23.976 then you end up with funky frames = in the copy. If you are lucky enough to have timecode burned in then you ca= n check the timing and make sure that 30 seconds is really 30 seconds, but = there is nothing you can do about funky playback. You=E2=80=99ll have to do= your work using the video as a time reference and just not worry about the= reference video.

This may make your work difficul= t to look at with a very critical eye, but if you are just creating graphic= s and you do not have the original video to work with, you just have to rel= y on the timing and send the client a comp or a render that matches their p= roject specifications.

I hope that makes sense. If= their video is the right length, the stutters and jerks during playback ar= e not important unless that is the only source of the video that you have.<= /div>

The only way I know of to verify that there are fu= nky frames in the video is to step through it one frame at a time. Force th= e video to run at a specific frame rate by setting the interpretation and s= tep through one frame at a time using the footage panel. If you get duplica= te frames or blended frames then the problem is in the recording and you mu= st get your hands on the original video.

I hope th= is helps.=C2=A0

I did try that actually. It is nded= up being all over the place, as the pattern was like a 12234445677 etc.=C2= =A0 No rhyme=C2=A0or reason other than both single extra frames and double = extra frames dispersed throughout.

I fear I may end up having to remake portio= ns of the graphics. Gonna be sloppy and not ideal I think.=C2=A0
