VideoProc - A Flexible Video Cutter to Trim Video in Various Ways

VideoProc makes video trimming easy with a great flexibility. It allows you to trim and separate video in various ways. You're able to trim the head and/or the tail of the clip easily, split videos in fragments, cut out the defective footage, or slow and repetitive scene and splice the reset together. The unique auto copy feature and Intel/NVIDIA/AMD hardware acceleration tech enables you to experience an ultra fast speed to trim a video without re-encoding. Certainly, you're able to cut a video after transcoding as well, which will get your video smaller in size but the same high quality. For example, converting HEVC to H.264 MP4 will help you save about 50% bit rate at the same quality of coding, leading to a half size of H.264 video with original quality.

Step 4: Export your trimmed video.

Hit "RUN" button on the lower right corner to export a new, shorter video, yet the same high quality. As you haven't set to re-encode your video, the video trimming process will be achieved in a blazing fast speed under auto copy feature. If your computer supports hardware acceleration (Check by clicking the "Option" button. If available, tick the box of Intel/Nvidia/AMD), it could be even faster.

Other Video Trimming Tips:

1. Re-encode video before video trimming. If you're willing to convert video formats before you slice off video, navigate to "Video" option at the bottom panel to choose the target output format before step 4, such as HEVC MP4, H.264 MP4, MKV, MOV etc. Or you can click "Target Format" button to choose from more preset profiles, up to 420+.

2. Split video into clips. There are also cases that your video is delicate, but it's too long for storage or sharing. Thus you can split it into fragments by clicking "Toolbox" at the bottom panel to choose "Split" button. Double-click it to decide how many segments you want split it to, or how many seconds to split for every segment.

3. Crop out video frame size. Usually, video trimming and cropping go hand in hand. If you need to crop the video frame size to adapt different aspect ratio, you can click "Crop" button on the editing bar, and tick the box of "Enable Crop" to set the video frame size and position.

Q1: "I've been using the YouTube video editor to combine clips, but I've needed the trim feature to slim them down and blend them together. Suddenly today, the trim feature does not work. I can still add the videos to the timeline, but nothing comes up when I click on the scissors icon. It's as if there isn't a link to click. Do I just need to wait?" - YouTube Help Forum

Q2: "Went into "Enhancements" under the video editor to trim off the first hour of my 5 hour livestream, saved the video (as the same video, not as a new video) and it took ages to process, but went back to check it today and it's done processing but the video was not trimmed. Anyone have any idea what's going on? Thanks!" - Reddit
