History of Video Merging — The Timeline
First digital video editing — In early 1990s, software like Adobe Premiere introduced the concept of combining two or more video clips at a timeline, you have to drag and combine multiple clips at this time in a single final video. But regular people could not afford this because the process needs an expensive hardware, and lots of technical knowledge.
Consumer video editing arrives — To fulfill the increasing demand for merging clips, Windows Movie Maker and iMovie made merging accessible for everyday users in 1999. For the first time in history regular people could drag clips in order and export as one final video. However, the functionality was not stable, quality was often poor and the software crashed frequently.
Online video sharing boom — When YouTube became popular, many people decided to start uploading videos. But to upload videos, they need a video editor without paying for any software. Desktop programs like VirtualDub and Avidemux became popular for merging videos. But the only issues was that, users had to download and install these softwares first.
First browser-based mergers — As web video technology and file handling features improved over time, developers start building video merging tools online. Early versions were slow and limited to only two clips, but with the passage of time, they improved video merging in browsers without uploading to servers.
Modern mergers with audio mixing — This is the time when merging videos online become so reliable that it start feeling like desktop software. Newer video mergers are providing features like background music, thumbnail previews, and audio mixing. ClikDeo video merger tool also have features like "Add background Music" and "Mute Original Audio" etc.
Privacy-focused, local-first merging — As the number of merging tools start increasing and tools became more reliable, People realized that uploading videos to random websites or servers is risky. Modern mergers like this one process everything locally. Your clips never uploaded to any external server, nor leave your computer.
Mechanism — How does video merging actually work?
People assume merging videos is like taping two film reels together. It's not. If you want to combine video and audio online, you need a proper audio and video combiner that load clips, calculate duration, render frames, and record the final stream. Here's what happens step by step when you upload clips and click the merge button:
- 1. Loading clips into memory — Whenever a user uploads a video to, the uploaded file is read using the browser's file API. As user can upload or use multiple videos to merge, tool creates temporary URL for each clip so it can be played back without uploading anywhere. All clips will stay in your browser's memory during process.
- 2. Calculating total duration — To merge video and audio online. Tool calculates each clip duration and then calculate the total duration of the finalized video. This also helps tool with progress tracking during merging process.
- 3. Setting up the canvas — When user uploads a first clip, tool creates a hidden HTML canvas element. The canvas element dimensions match the dimensions of first uploaded clip. If next uploaded clips have different dimensions then tool scale them to adjust according to canvas element dimensions.
- 4. Frame-by-frame rendering — Tool moves from your first clip from start to end on a hidden video element, at about 30 frames per second. Tool draws that frame on to the canvas. This creates a visual stream of the video.
- 5. Audio handling — When tool draws clip frames on to the segment, tool will also extract audio from your original video using Web Audio API. After that Web Audio API connects these audio context with video's audio track. If you have muted original audio of uploaded clips, then those clip tracks will be ignored. And if you have added background music, then that music will also mixed in original video's audio track.
- 6. Recording the merged stream — The MediaRecorder API is responsible for capturing everything drawn on the HTML canvas element along with mixed audio. It saves this separately and then assembles them into a single video blob. As all the processing and merging clips is a real time task, so merging a 10-minute video takes about 10 minute.
- 7. Creating thumbnail previews — Whenever user select a clip, tool generate preview thumbnails for every clip in your timeline. This preview thumbnails have multiple frames from the selected video file. These thumbnails helps you to identify which clip is without play clip.
- 8. Providing navigation controls — In the final merged video, tool tracks the points where each original clip starts and ends. Back and Next button below the merged video player helps you to jump directly to the beginning of each clip, which helps to find each clip in final merged video.
- 9. Downloading the final file — After merging, when you click download button, Audio and video merger saves the video blob to your computer as an MP4 or WebM file. The original clips will remain untouched on your computer.
Important notes: All the processing done in your computer. So, merging takes as long as your clips length. For example, if you have three clips, each clip is 2 minutes long and the merged video will be of 6 minutes, merging will take about 6 minutes. If you have an older computer, it might take a bit longer.

Videos merged with this audio and video combiner are standard MP4 or WebM files, nothing special. So, you can treat these videos like normal videos. You can upload them anywhere you'd normally upload a video. Here are some common platforms listed below, where people uploading these edited videos:
