What is Video Trimming? Everything You Need to Know
Let us discuss about the complete evolution of video trimming, From cutting physical film strips with scissors to real-time trimming.
So What Exactly is Video Trimming?
The term video trimming itself shows what its all about - you upload a longer video and cut off the parts you don't want. The beginning part, ending part, or even a boring middle section where nothing happens. The remaining part with good stuff is the actual part you want to keep.
Trimming videos is the most interesting and commonly used editing technique. I have been editing videos for over two years and trimming is the only thing I do more than anything else. The best part about trimming is that, you recorded a 30 minute Game play video, trim it to 5 minutes. Recorder a food vlog with boring intro? cut it down to the main content.
A best trimmer doesn't re-encode your whole video, it just cut out the unwanted parts and stitch the remaining main parts together. Thats why good trimming tools are fast.
The History of Trimming — From Razor Blades to One Click
Back in the 1890s, trimming was not an easy method. If you wanted to trim a video, you literally took a scissor and cut the physical film. Then taped the main content ends together. Filmmakers like Georges Méliès found this method by cutting and rejoining films. They could also create special effects, but the issue is that trimming was permanent. No undo button. No preview. Just a cut, rejoin and hope you didn't mess up.
In 1924 Iwan Serrurier invented a device called " The Moviola ". A device that let editors to view film while trimming. For the first time editors could see what they are trimming before making the final cut. Hollywood filmmakers went crazy after this invention. This machine was used over half of the century.
After 50 years of the Moviola, some one really thought about the regular people. Adobe released Premiere 1.0 for Macintosh (Now commonly referred to as MAC). This was the first time when regular people could trim videos on a home computer by sitting at a couch. But the issue was that the software was painfully slow. A simple trim could take up to 30 minutes or more.
The invention of Final Cut Pro changed editors life. For the first time trimming was real-time. Just drag and drop your videos and see exactly what you were cutting in real-time. Professinal editors switched to Final Cut Pro with no time because trimming became so intuitive.
In February 14, 2005, when YouTube appeared, Everyone suddenly felt to trim their videos. Because people started to upload everything, Concert videos, family videos, game clips, movies. With the passage of time, the demand of trimming started increasing and the online trimmers started appearing. They were terrible at first. Low quality, Watermarks everywhere.
In today's Era, we have WebCodecs, MediaRecorder API's, and hardware in browsers. This means trimming happens instantly. No uploads, No watermark, No software installation, right in your browser. Just select the video, drag the handles to select the area, start processing, click download, and you are done. ClikDeo is the tool, I am talking about, to make trimming so fast and simple, right in your browser.
How Does Video Trimming Actually Work?
Let me explain the actuall process in simple words without making this complex.
You just need to upload the video file. Your browser doesn't send the uploaded file to anywhere. It just read the uploaded file from your computer. Think of it like writting words in a book. Words are there, not going anywhere from the pages.
Every video is made of individual pictures called frames. An average 1-minute video at 30 frames per seconds, has 1800 still images. When you drag the handles to select the trimming area, the tool is actually calculating which number of frames you want to keep in your video or not. Think of it like, you select frames from 0 to 45, keep them. From frames 45 to 1800, cut them.
This is the part where magic starts. The tool takes the frames you want to keep and copies these frames to a new video file and the same goes with audio files. After copying frames it stitches everything together. Have you ever used scissors to cut a strip of page and taped it back together? trimming is the same concept, but digital.
Once the cutting process is done. you can download the new trimmed video. And because timming process happened on your computer, your original video is still safe. Nothing was upload to anywhere else, nothing was deleted. Just a new and shorter video ready to download and use.
Image two slices of a bread. Trimming is like cutting the edges at both ends and keeping the soft middle slices. Or if you are keeping the outward, then keep the edges and throw away the middle part of the slices and stitch the edges from both end. That's trimming is, Keeping the parts you want and discarding the rest.
Keep Inward vs Keep Outward — What's the Difference?
This confuses a lot of people at first. Let me clear it up with real examples.
Keep Inward
What it does: You select a part with sliders and keep the part between the sliders. Removes everything else outside the sliders.
When to use it: Let's talk with an example. You recorded a 5-minute video but onlt the middle 2 minutes are good. In the beginning you were clearing you throat, while in the ennding, your motions or actions were not stable. Use "Keep Inward" to keep only the good middle part.
Example: Your video is 0:00 to 05:00. You set start at 2:00 and end at 4:00. The final video will be 2 minutes long — from 2:00 to 4:00.
Keep Outward
What it does: Keep Outward means remove the part of a video between the sliders and keeps everything else.
When to use it: Image you recorded a video with boring middle part because of some reasons like device issues, actors not stable. Beginning is great, ending is great. But there's a middle part that adds nothing to your video. Use "Keep Outward" to cut out that boring part and stitch the good beginning and end together.
Example: Your video is 0:00 to 05:00. You set start at 2:00 and end at 4:00. The final video will be 5 minutes long — from 0:00 to 2:00, then immediately from 4:00 to 05:00. The middle section is removed.
Who Actually Uses Video Trimming? (Real Life Examples)
People use video trimmer every day for all kind of things. Here are some real life use cases listed below.

What I've Learned After Trimming Thousands of Videos
After working as an editor or trimming thousands of videos like home videos to professional content, Some major points are,
- Always leave a tiny buffer. Don't trim your video exactly from the frame where someone start speaking. Leave a 0.5 second gap and trim. This gives more natural touch.
- Trim the silence, not the breath. Remove a part where someone taking breath before speaking. Sounds robotic.
- Watch it back at least twice. Trim weird jumps in audio or video and clear your video from unwanted points. but before posting make a complete scan one more time.
- Save your original file. Save your original file in another folder before start trimming to be safe from any mishaps.
- For social media, shorter is almost always better. Cut long videos into 30 - 60 seconds parts, best for creating engaging content for social media platforms like TikTok, Instagram, YouTube etc.
