Why Your Uploaded Video Won’t Play Correctly and How to Fix It
— Zeynep
If you're reading this article, it's likely because you just tried uploading a video through our platform, and received a warning that the video doesn't play properly—especially on Android phones.
Let us explain why this is happening, what’s technically wrong with your video, and how to fix it easily.
❗ What’s Wrong With Your Video?
Your video file is a valid MP4, but it’s not streamable—which means some devices and messaging apps (like WhatsApp) won’t be able to play it immediately. Instead, the video may:
- Fail to play entirely on some Android phones
- Require users to download it fully before watching
This happens even if the video plays fine on your computer.
✅ How You Can Fix It
You have a few options—some are quick and online, others are more advanced.
🔄 Option 1: Use an Online Converter (Quick & Easy)
The fastest fix is to re-upload your video to a tool like CloudConvert:
- Visit cloudconvert.com/mp4-converter
- Upload your original video
- Select MP4 as the output format
- Click Convert
- Download the new file and try uploading it again
This will place the moov box in the correct position and make the video streamable.
💻 Option 2: Fix it Using FFmpeg (Advanced Users)
If you're familiar with command-line tools, use FFmpeg:
ffmpeg -i input.mp4 -movflags +faststart output.mp4
This command moves the moov atom to the beginning of the file, which fixes the streaming issue.
📱 Option 3: Let WhatsApp Fix It
Here’s a clever workaround using your phone:
- Send the problematic video to your business WhatsApp number from your own mobile device.
- Download that same video from our platform.
- Re-upload this version to our platform.
WhatsApp optimizes and re-encodes videos on mobile before sending, so the downloaded version is usually in the correct format.
