<p>Since your source is in h264 I'm guessing you are encoding to mp4/h264 again?
The format doesn't support a frame rate of 99, you will have to use a less constrained video codec like mjpeg in an avi or mov container.</p>

<p>Whenever you are violating certain video or audio specs After Effects will tell you that in your export settings like shown here (see the little warning triangle in the left corner). AME doesn't do that for some reason but will show the adjusted settings in the source output info field.</p>

<p>I've got a composition with only a video that was recorded at 100 fps. Apparently 100 fps is to much for AE, but it deals just fine with 99, which is OK to me.</p>

<p><img src="https://i.sstatic.net/2oHQM.png" alt="enter image description here"></p>

<p>The composition was set with exactly the same settings as the video. But when I render this, even choosing <code>Best Settings</code> or <code>Current Settings</code>, both with base 99 (<code>Use comp's frame rate</code> option) it outputs a 60 fps video.</p>

<p>I didn't even set 60 anywhere else, I do not know from where it is coming. But the thing is, I need to output it as 100/99 fps.</p>

What is your intent with this test? High frame rate is often used with slow-motion and when one edits slow-motion the output is usually your typical 23.976 or 25 FPS. Why would one need to render at 100 FPS in the first place?

@ScottJamesWalter Because, I think that one frame difference may be creating a problem. I am trying to create a slow motion scene. The problem is: when you play the video at normal speed, the sound is ok, synced with the video. However, at slow motion, it is not. Then I've noticed, that even at normal speed, the sound is ahead as it was supposed to be on the timeline, but AE tries to compensate it and pretends it is fine. And 60 fps would not be as good as 100 fps in slow motion.

@ScottJamesWalter I don't think it is a duplicate, as I know which frame rate I am, and which frame rate I am rendering. The problem is, why it is not rendering at the frame rate is was supposed to render. Anyway, that question might help a bit though.

@ScottJamesWalter Just looked at that question, and AE was with a wrong interpretation of some footage frame rate on that, which the picture I uploaded show that this is not the problem. The videos were filmed with a GoPro and were filmed at 100 frames per second .

The answer to that question may help you solve your own issues. Additionally, maybe the README for AE, specifically the framerate section may help you: http://helpx.adobe.com/after-effects/using/importing-interpreting-footage-items.html#frame_rate It sounds like you're using AE is a NLE. How long is this slow motion sequence? When it comes to audio and slow motion, it may not be the best idea to mix the two. I'll leave it to someone with experience to address that issue.

@ScottJamesWalter I know what I am doing. I could done exactly what I want with the 60fps output, and the sound was distorted just as I wanted too. But as said, 60 fps does not look as good as 100 fps in slow motion. My only problem, is that. It is not outputting what I want and what I've setup, and I want to understand why.

You realise that if you output it at 100fps it won't be slow-mo, it will be real time, don't you? You make it slow mo by changing the frame rate, for example taking a 10 second 100fps video and playing it back at a quarter of its speed gives you a 40 second 25fps video.

# After Effects rendering a video at base 99, but outputs as a 60 one

(Asked by: username_0 on 2014-08-25)

I've got a composition with only a video that was recorded at 100 fps. Apparently 100 fps is to much for AE, but it deals just fine with 99, which is OK to me.

The composition was set with exactly the same settings as the video. But when I render this, even choosing `Best Settings` or `Current Settings`, both with base 99 (`Use comp's frame rate` option) it outputs a 60 fps video.

I didn't even set 60 anywhere else, I do not know from where it is coming. But the thing is, I need to output it as 100/99 fps.
