I am capturing video on my Canon 7D at 60fps with the intent to play it back in slow motion at 24fps. There are some Linux-based programs that will do this, but they are usually kind of buggy and I'm running Windows mostly now. How can I convert a 60fps video into a slower (2.5x longer) video at 24fps?
You can import the movie into Blender and then export it with a different framerate using this technique:
1. Import the movie
Open up a "Video Sequence Editor" in a fresh Blender-scene. You should see something like below:
Click on Add > Movie and select the movie you want to convert. Make sure that the Blend-option (open the panel on the right with N) is set to Replace and Start Frame is 1 (see picture).
2. Export the movie
Then you go to Render Settings:
Make sure that you have selected the correct Resolution (the one of the video) and the slider is at 100%. Set the End Frame to the same as the Length of your video (seen in the picture 1 below Start Frame). Select the correct Frame Rate (24?) and the right format (I selected AVI Raw but it can be everything you like). Hit that Animation-button or Press Strg+F12 to render.
If you have any questions, feel free to ask.
First, You need to Output your video as a Image Sequence.
This is a simple walkthrough for your.
Start a new blend file.
This will render out your video.
Now, Change Your View to Video Editing.
Since you are using the same blend file, you don't need to change the resolution or end frame length. However, change the Frame Rate to lower number (it is just beneath the End Frame below Fram Range Option.
This will output your video to a desired fps with desired encoding at your chosen folder.
