GFX protected video
Choose GFX when the recipient can use the GiliSoft protected player and the package should remain a dedicated encrypted media file. GFX is also the practical choice when the protected output is larger than 4 GB.
The Quick Answer
An encrypted video needs a matching protected player or package.A normal media player expects an ordinary MP4, AVI, WMV, or other open media file. GiliSoft Any Video Encryptor instead creates password-protected GFX or Windows EXE output. The recipient opens that protected output, enters the password, and watches through the controlled playback process.
This is useful when a training video, private preview, customer demonstration, or offline media package must leave your computer without becoming an ordinary source file. The protection travels with the package rather than depending only on the folder where it was stored.
What Is an Encrypted Video Player?
An encrypted video player is a playback client that understands a protected media format and can verify the information required to open it. That requirement may be a local password, a package key, or a DRM license. Microsoft describes the same underlying pattern for protected media: content is encrypted before delivery, and a capable client decrypts it while enforcing the rights attached to playback.
With GiliSoft Any Video Encryptor, the process is local and password based. The sender encrypts the video as GFX or EXE output. The viewer receives the protected package rather than the original video and must provide the correct password before playback begins.
Important: renaming an MP4 file, changing its extension, or placing it in a ZIP archive does not create an encrypted video. The content must first be processed by encryption software that also supplies a compatible playback route.
Encrypted Player vs Normal Player vs DRM Player
| Playback type | What it opens | Access check | Best fit |
|---|---|---|---|
| Ordinary media player | Standard MP4, AVI, WMV, MOV, and similar files | Usually none | Open media intended for normal playback and sharing |
| GiliSoft protected player | Password-protected GFX packages | Local playback password | Simple offline delivery where the source video should not remain open |
| Protected EXE package | Self-running Windows video package | Password; optional authorized USB binding | Portable Windows delivery without a separate player installation |
| DRM player or client | Licensed protected media | License, account, device, expiry, or policy | Commercial training, revocation, expiry, device control, and traceable distribution |
How Password-Protected Video Playback Works
- 1Add the source videoLoad the video or media files in GiliSoft Any Video Encryptor. Keep a backup of the unencrypted source in a controlled location.
- 2Choose GFX or EXE outputUse GFX for protected-player playback, especially for larger packages. Use EXE when the recipient needs a self-running Windows file.
- 3Set and confirm the playback passwordUse a password that is not sent in the same message as the protected package.
- 4Deliver the protected outputCopy the verified GFX or EXE package to local storage, a USB drive, an external drive, or another offline delivery channel.
- 5Open and verify playbackThe recipient enters the password and watches through the protected playback process instead of opening the original source video.
Choose GFX or EXE Output
Windows EXE package
Choose EXE for a self-running Windows package. EXE output has a 4 GB limit. It can also be bound to an authorized USB drive so the package does not open when separated from that drive.
Delivery rule: test the finished package on a second Windows PC before sending it. Confirm the password, playback, sound, seeking, and USB binding if used.
What Protected Viewing Adds
Password before playback
The viewer cannot simply double-click the original open video.

No ordinary Save As route
The viewing process does not hand the recipient the original source through a normal player command.

Portable offline delivery
GFX and EXE packages can be delivered on local or removable storage without requiring a streaming platform.

No desktop protection can honestly promise that a camera pointed at the monitor will be impossible. For higher-value commercial video where you need account control, dynamic watermarking, device binding, password revocation, or expiry rules, use GiliSoft Video DRM Protection.
Local Encrypted Playback or Video DRM?
Choose local encrypted playback when a known recipient needs a straightforward password and the content is delivered as a file. It is practical for private previews, offline training, internal demonstrations, classroom material, or video packages carried on removable media.
Choose DRM when the business needs to decide who can play the video after delivery, how many devices are allowed, when access expires, whether a leaked password can be revoked, or how visible watermarks identify the viewer. Microsoft documentation similarly distinguishes protected playback from ordinary media playback by requiring a capable client and valid rights or license information.
Why an Encrypted Video May Not Open
Wrong player or file association
An ordinary video player cannot decode a GFX package. Open it through the supplied protected player workflow.
Incorrect password
Confirm capitalization, keyboard layout, and copied spaces. Do not repeatedly guess if the sender can verify the password.
Incomplete or damaged copy
Compare the delivered file size with the sender's output. Recopy the package if a transfer or USB removal was interrupted.
USB-bound EXE is separated
Reconnect the authorized USB drive before launching a package created with USB binding.
Windows blocks an EXE
Managed PCs may restrict unfamiliar executable files. Ask the organization administrator to verify and approve the package.
Platform mismatch
EXE packages are for Windows. Use an appropriate protected format and playback environment for the recipient's device.
Encrypted Video Player FAQ
Can VLC or Windows Media Player open an encrypted GFX video?
No. Those players handle ordinary media formats. A GFX package needs the matching protected playback component.
Can an encrypted video play without the internet?
Yes. GiliSoft GFX and EXE packages are designed for local password-based playback. This differs from an online DRM workflow that may acquire or validate licenses.
Does the viewer receive the original MP4?
Not through the protected package. The sender distributes GFX or EXE output rather than the ordinary source video.
Can I play a protected EXE from a USB drive?
Yes. A Windows EXE package can be copied to a USB drive, and optional USB binding can require that authorized drive to remain connected.
Which format should I use above 4 GB?
Use GFX. EXE output is limited to 4 GB.
