How to Create Custom Video Boot Animations

Requirements

Android 4.4 KitKat (Lollipop and Jelly Bean devices are incompatible)

Rooted device

No TouchWiz (Samsung devices are not compatible)

Step 1: Download the Video Boot Animation Binary File

The main element behind this mod is a ported version of Motorola's boot animation binary. This file allows you to utilize video boot animations on your device, and it can be downloaded Here

Step 2: Copy the Binary File to Your Device

Once you've downloaded the binary file, you'll simply need to place it in the proper folder to enable video boot animations on your device. The folder in question, however, is located on your root partition, so you'll need a root-enabled file browser to access it.

I'll be using FX File Explorer to demonstrate, which is a free app available on Google Play. If you opt to use FX as well, make sure you also install the Root Add-on. FX File Explorer Download

Head to the Download folder on your device, then long-press the bootanimation file and select Copy.

Next, head back out to FX's main menu, then select System (Root) to access your device's root partition. Tap Grant on the Superuser Request message, then tick the box next to "I Understand" and press OK on the popup that appears next.

From here, head to the System folder, then the Bin folder inside of it.

Before you can make any changes to this folder, you'll need to mount it as "Read/Write." Tap the Lock Icon at the top of the screen to do so, then tick the box next to "I Understand" and press OK on the popup again.

Next, you'll need to do something about the existing boot animation binary file on your device. Long-press the bootanimation file that you find in this folder, then select Rename. After that, simply add a .bak to the end of the file name, then press OK.

With that out of the way, tap the Clipboard button in FX, then paste the modified bootanimation binary file in its place.

Finally, long-press the newly-copied bootanimation file, then select Permissions. Make sure that the Owner category is set to Read, Write, and Execute, while all other categories are set to only Read and Execute.

Step 3: Select a Video Boot Animation

With the new bootanimation binary file in place, your device is now capable of using video boot animations. The mod's developer has provided a few sample animations to choose from, and you can view them at his support thread.

To download a copy of one of these video boot animations, use the following links:

Marvel/DC Comics Animation

Droid Animation

Step 4: Copy the Video Boot Animation to the Right Folder

As was the case with the binary file, you'll simply need to copy your new video boot animation file into the proper folder. Head to your device's Download folder again, then long-press the bootanimation.zip file and select Copy.

After that, head back to the System folder on your root partition, but this time go into the Media folder inside of it. Again, make sure that the folder is mounted as "Read/Write" so that you can make changes to its contents.

From here, long-press the existing bootanimation.zip file, then select Rename. Add a .bak to the end of the file name, then press OK.

After that, tap the Clipboard button, then paste the new boot animation file into this folder. Make sure that the new file is named simply bootanimation.zip.

Once again, you'll need to make sure the permissions are set properly for this file. Bootanimation.zip files should have the Owner category set to Read and Write, with all other categories set to just Read.

With all of that taken care of, your new video boot animation will be in place—simply reboot your phone to give it a try!

Now Create Your Own Boot Animation

If you'd like to try your hand at creating your own boot animation, there are a few simple ground rules. You'll need two videos to serve as a part 1 and part 2 of your animation, they'll have to match your device's resolution, and they'll need to be in the MP4 format.

Beyond that, it's only a matter of replacing the MP4 files contained within any of the sample video boot animation files with your own, then placing the new file into your /system/media folder.
