ffmpeg rotate video 90 degrees counterclockwise

We can also combine multiple transpose filters to change the orientation of the video. We’ll get this output when playing the output_0.mp4 video: This is the default preset if we don’t pass any values to transpose. This will change the video orientation to portrait. We’re passing the value 0 to the transpose filter which rotates the video counterclockwise and vertically.

Let’s create “in.txt” with the following content: To merge video file you want to create a text file. t switch is not end time but it is frame duration time you want to cut Merge MP4 Video ss switch indicates the start time of the frame you want to cut I want video frames at 4 points like 10-23, 25-31, 32-40, 42-47 seconds, so I cut those frames like below command.ġ0-23 Secs => Cut video from 10 sec to 23 sec for duration of 13 secĢ5-31 Secs => Cut video from 25 sec to 31 sec for duration of 6 secģ2-40 Secs => Cut video from 32 sec to 40 sec for duration of 8 secĤ2-47 Secs => Cut video from 42 sec to 47 sec for duration of 5 sec

You need to make sure FFMPEG is on your system environment PATH. I am using it to perform all kinds of amazing manipulations on video and audio files since 2008, so I know all tricky commands. I was trying KineMaster to Cut few MP4 video frames from a video file, but KineMaster is not so good to cut sections from videos and merge those again as compared to FFMEPG tool.įFmpeg is a very good tool.
