I downloaded some files to work on an edit in after effects but I ran into a problem that I've had with after effects for a while. When I try to import clips(footage) that is 300+ fps and an avi. file It will not allow me to import them. Here's the link to some clips I tried to download but wouldn't import.

Looking (Roblox Clips & Cines in desc) - YouTube

Why in the world would you want to bring 300 movies into After Effects? AE is not an editing app. AE is for creating shots you can't create anywhere else.

I see from your YouTube sample that they are all screen capture clips. The format could be wrong.

I didn't read your post closely enough.

300 fps footage is extremely odd and would not playback in real time on hardly any system. The frame rate, if it is defined by the metadata, has nothing really to do with the format or whether AE can import the footage. If the frame rate is not included in the metadata, would be guessed at. Cameras and phones and even screen capture apps may not capture at an even frame rate but any NLE will not read the changing frame rate or drop frames. The only thing that may happen is that the playback time may not correspond to real time. As long as the frame rate of the sequence or comp matches the interpreted frame rate of the footage, you will see every frame.

I see from your YouTube sample that they are all screen capture clips. The format (codec) and compression are most likely incompatible with video production. Transcoding to a suitable production format may be the solution. Once you get the footage inside AE you can interpret the frame rate as anything you like within the limitations of the app and use that to control the speed of playback.

Almost every time I see folks talk about frame rates they completely misunderstand how video works and what the frame rate means and does. It may help you get an answer if we knew what you were planning to do with the HFR footage.


By knowing what I plan to do with the HFR footage, does time remapping and motion/camera tracking answer the question? When I use the time remapping feature and make the video speed very slow down to the point where a 60 fps video would look choppy, with 300 fps it will still look smooth. (Also, in the past I have been able to get 300-600 fps footage working)
