Trim video, audio without loss, take snapshots, with LosslessCut
You can use this nice application to trim and cut parts of your videos without losing quality.
Just load the file and use the start/stop marks to specify the section that you want to cut and save. Click the cut icon and the marked section will be exported to a new video file without any decoding or encoding.
The program is very convenient for processing quickly large video files. It lets you extract the good parts from your videos and discard lots of data without quality compromises. The program supports also lossless cutting of the most common audio formats.
You can also use the program to take a quick JPEG snapshot of a scene. LosslessCut uses ffmpeg (included). If you get an error when cutting a file, please check your anti-virus. It might be blocking the execution of ffmpeg.
