Question

After effects lag with high fps clips

I got a question.. I'm currently using After effects CC 2014 (due to my preference). And I am trying to edit a csgo montage, the clips that I am using are filmed at 600 fps. Once I try to render one frame of the clip it takes about 4 seconds(on quarter), and my pc fans go wild, plus my cpu goes from 35c to 70c(for the seconds pre-rendering). Is there any way I can use the 600 fps clips without getting those lags, or at worst, damaging my computer? The files are mp4, and im not using any type of effects on them at the moment. I know other people have used clips like these with no problems, I just wonder if there's something im missing?

I have 32 GB DDR4 3000MHz ram (24 GB used for after effects)

plus intel i7 7700k oc at 4.8ghz

win 10

    Transcode your clips to a nice intermediate codec.  You're on CC 2014, so you still have access to a LOT of nice quicktime codecs.  Yes, the file sizes will be larger, but AE will have a heck of a lot easier time not trying to figure out the interframe calculations that mp4 imposes on 600fps footage.

    It sounds to me like you do not have a good understanding of frame rates and how to deal with them. Nothing will playback at 600 fps. That is way beyond normal for an MP4 file. If you want to see every frame then the easiest thing to do is change the interpretation of the footage so that it matches the frame rate of the comp. If you are working at 30 fps then select the footage and use the File menu to open up interpretation. Set the frame rate to 30. Now you will see every frame, but 1 second of real time will take 20 seconds to playback so the action will be in slow motion.

    I'm assuming that when you said csgo montage you are talking about a video game. It's highly unlikely that the video capture was done at 600 fps.

    We need a lot more info to give you any meaningful help.
