Importing 300+ avi. file

Report · Jun 23, 2018

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.

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)

If you want to slow down the footage the best thing to do is to change the interpretation. If the original footage is truly 300 fps and you interpret it as 30 fps then 1 second of real-time will take 10 seconds of screen-time. Then you can use time remapping to speed it up to real time.

The format of the footage is probably the problem. Screen capture at 300 fps is probably a wonky format. I would see if there is some way to transcode to a production format. Unless you tell most software to retime the frame rate you will not lose any frames.

If the footage is really 300 a recording that captures 300 frames every second you should not lose any frames. The metadata that reports the frame rate has nothing to do with the actual frames that are recorded. If the same software was used to make the screen recordings that worked then a change in AE version or a change in the screen recording software could easily foul up the footage so AE can't read it.

To check and see if an AE update is the problem try importing footage that worked before. If it works, check the format and compare it to the footage that will not work. Anything changing in your system could cause the problem. Without some sample footage to test I canb't tell you much more than that.

Hi, sorry not getting back to you for a while. I was able to find some footage that would work. 'LoveLife' - CS:GO Edit [Clips in desc.] | 1k subs special (Read desc.) - YouTube
