Videos are no longer just a part of marketing campaigns or entertainment; they’re central to how we communicate and engage with audiences, whether it’s in online courses, social media, or digital content platforms. However, the process of uploading large video files can be a bottleneck, especially when users demand speed, reliability, and instant feedback.
This is where things often get frustrating. The experience of waiting for a file to upload, only to face delays or failures, isn’t just inconvenient; it’s a roadblock. So, how can we simplify this process and eliminate the pain points?
In this post, we’ll show you how to automate and optimize video uploads using techniques like chunking and resumable uploads, paired with webhook notifications to keep users informed in real-time. With these strategies in place, you can build a seamless, efficient video upload workflow that not only saves time for developers but ensures a smooth, hassle-free experience for end-users.
When it comes to uploading large video files two most important aspects are: speed and reliability . Whether you’re an instructor uploading a lecture or a production company delivering high-quality 4K content, slow or interrupted uploads are simply unacceptable.
For example, consider an online education platform where instructors routinely upload video lectures. These files can range from 500MB to several gigabytes, and instructors may be working from regions with unstable or slow internet connections. Without accelerated uploads, a minor network disruption could result in the entire file needing to be re-uploaded from scratch, wasting hours and causing unnecessary stress.
Similarly, video production companies dealing with large 4K or 8K video files need fast and reliable upload processes to meet tight production schedules. With accelerated uploads, even if an issue arises during the upload, the process can simply resume from where it left off without any data loss.
The challenges of uploading large video files are clear
This is where accelerated uploads come in. By breaking large video files into smaller chunks, uploading them in parallel, and enabling resumable uploads, these techniques ensure speed and reliability. Even if a network issue occurs, the upload can resume from where it left off, making the entire process much more efficient and user-friendly.
To implement accelerated video uploads, you can use chunked uploads and resumable uploads. These approaches break up large files, upload them simultaneously, and allow the process to continue from the point of interruption, optimizing both speed and reliability.
Break the video into chunks: Breaking the video into chunks allows you to upload smaller, manageable pieces of data. Each chunk can be uploaded independently, which reduces upload time and allows for faster recovery in case of network failure.
1/**
2 * Splits a file into smaller chunks for upload.
3 * @param {File} file - The file to be split into chunks.
4 * @param {number} chunkSize - The size of each chunk in bytes (default: 1MB).
5 * @returns {Blob[]} Array of file chunks.
6 */
7function createFileChunks(file, chunkSize = 5 * 1024 * 1024) {
8 const fileChunks = []; // Array to store the chunks of the file.
9 let currentPosition = 0; // Tracks the current position within the file.
10 // Loop until the entire file is processed into chunks.
11 while (currentPosition < file.size) {
12 const nextPosition = Math.min(currentPosition + chunkSize, file.size); // Calculate the next chunk boundary.
13 const fileChunk = file.slice(currentPosition, nextPosition); // Extract the current chunk.
14 fileChunks.push(fileChunk); // Add the chunk to the array.
15 currentPosition = nextPosition; // Move the position to the next chunk start.
16 }
17 return fileChunks; // Return the array of chunks.
18}
19// Add an event listener to handle file selection
20const fileInput = document.getElementById("fileInput"); // Input element for file selection.
21fileInput.addEventListener("change", (event) => {
22 const selectedFile = event.target.files[0]; // Retrieve the selected file from the event.
23 if (selectedFile) {
24 const fileChunks = createFileChunks(selectedFile); // Generate chunks from the selected file.
25 console.log(`Total Chunks: ${fileChunks.length}`);
26 } else {
27 console.error("No file selected");
28 }
29});
Upload chunks sequentially or in parallel: You can upload chunks either sequentially or in parallel. Uploading in parallel can improve performance, but you should ensure your server can handle multiple requests at once.
Handle resumable uploads: If the upload fails (due to a network issue, for example), you can resume the upload from where it left off instead of starting from the beginning. Use the online and offline event listeners in JavaScript to monitor network status. These events help pause uploads when offline and resume them when the connection is restored.
1window.addEventListener("online", () => {
2 console.log("Network is online");
3});
4
5window.addEventListener("offline", () => {
6 console.log("Network is offline");
7});
Optimize for network interruptions: If the network connection is interrupted, you can use the saved information (e.g., uploaded chunks in localStorage) to continue uploading from the last successful chunk. To effectively manage the upload state, maintain an object that dynamically updates throughout the process, tracking key details.
For the accelerated upload process, FastPix Uploads provides an all-in-one solution that simplifies and enhances the chunked upload experience. With built-in features like pause and resume, the SDK ensures that video uploads are fast, reliable, and resilient to network interruptions.

Users expect updates to happen instantly no waiting, no delays. Webhooks are a powerful tool that help systems communicate in real-time by automatically sending notifications whenever a specific event occurs. Instead of repeatedly checking for updates (which can be slow and inefficient), webhooks send updates as soon as an event happens, keeping everything running smoothly and quickly.
A webhook is like an automatic alert system. It’s a way for one system to notify another system whenever something important happens without any manual checks or delays. When an event occurs (like a video being uploaded or a user making a payment), the system sends an instant HTTP request to a designated URL, notifying the other system about the event.
This method eliminates the need for constantly polling (checking repeatedly) for updates. Instead, webhooks provide a more efficient, instant, and automated way to stay updated.
To know more about webhook please go through our content on webhooks for real time.
Webhooks are incredibly versatile and can be used in various scenarios to automate workflows and ensure that systems stay synchronized in real time. Here are some common use cases where webhooks can make a difference:
Video encoding completion
