  • Rendering at different frame rates

    Posted by John Mark on October 11, 2012 at 8:04 am

    I am having trouble dealing with two different frame rates when I render on after effects, I have the video running at 29 Fps but want to add a graphic that is 60 Fps then when I render them together the video lags and basically does not play, any idea on how to fix this.

    Thank you.

    First I think you mean 29.97 fps, as there is no 29fps standard.

    You should convert the graphics to the same frame rate as your video- 29.97- Interpret the footage to 29.97 fps (this will double the length of the clip) then enable Time Remap and create 2 keyframes (one at the beginning of your clip and one at the end). Bring the last keyframe to the middle of your conformed clip to speed up to real time.

    AE’s default lossless output module generates an intermediate file that is designed for additional post-production use, not direct playback. These files are generally huge, with very high data rates, and very few computers can play them back in real time without stuttering. For more, see this Adobe FAQ [link]: Why is my output file huge, and why doesn’t it play back smoothly in a media player?

    To help you choose a more suitable format for your needs, see the related Adobe FAQ [link]: What is the best format for rendering and exporting from After Effects?‘>Adobe FAQ [link]: What is the best format for rendering and exporting from After Effects?

    You need to give us more information- what is the exact frame rate your final product should have?
    Is the video 30 or 29.97fps?
    Are the graphics at 60 or 59.94 fps?
    It is hard to point out the problem and give advice without the exact details.
    Walter gave you an answer as to why your file may play slow on your machine.

    Sorry guys for the poor information. The video itself is 29.97 frames ok, and when I place the graphic (lower third) I go up to Composition settings and change it to 60 frames and its says 60 NOT 59.94, it needs to be 60 FPs because it runs much smoother. So when changing the setting of the frame rate up in composition setting changing it to 60 would change both the graphic and the video. So how can I just only change the graphic frame rate to 60 and leave the video just at 29.97.

    Sorry if this did not help again.

    You can only have one frame rate for the composition.

    Think about what this will eventually become — a single piece of video that will play somewhere. You must choose a single frame rate, and it makes the most sense to work in the same frame rate as you must deliver to. Anything assets not already in that frame rate will have to be converted or conformed.

    So — what are you ultimately going to do with this video?

    [Dave LaRonde] “When you look at the clip’s frame rate by highlighting it in the project window and looking at the info at the top, what does it say? 29.97 FPS
    When you drop the footage onto the Make Comp icon at the bottom of the project window, it makes a comp reflecting the footage’s specs. When you look at that comp’s Comp Settings, what’s the frame rate? it also says 29.97
