Since I don't have the file itself, I’ve put together a guide to help you identify, open, and manage this specific type of media safely. 1. Identifying the Source
Look for the or "Encoder" tags. This will tell you if it was made by an iPhone, an Android, or a specific editing software.
Use VLC Media Player . It can play almost any MP4 regardless of how it was encoded.
Before opening, run the file through VirusTotal.com .
Ensure it actually ends in .mp4 . If you see .mp4.exe , do not open it —it is malware. 5. Metadata Investigation
This is usually a unique ID assigned by a database. It is very common for files saved via Telegram bots or Discord CDNs to use this format. 2. How to Open the File Safely
The file might be a "Mute MP4" (often used for GIFs) or uses an AC3 audio track. Try VLC.
