Subliminal Video

介绍

Subliminal Video为一款可在视频中添加隐藏图片和信息的应用程序。
可根据需要选择和自定义许多视频帧，并可使用新的图片和文字替换它们。

大多数观看者不会看到这些潜藏的图片，它们显示的时间非常短。
但是，这会对他们的大脑产生无意识的影响。
这款应用程序可用来娱乐，或戏弄你的朋友们。

增添视频观看效果，更改多个帧以创建特效（给一些图片添加颜色、对图片某个部分缩放、更改图片、显示自定义文字,...)

该应用程序还可用来给视频添加文字标签(例如，你的签名)，这样人们可看见(但有些轻微隐藏)，以证明视频是你的。

您将看到原始直观的用户界面，与我们所有的视频应用程序相同。
这些应用程序已多次被苹果和其他各网站收录。

此应用程序可在iPhone和iPad上运行，需要iOS5或更高版本的系统，设备需要有前置摄像头。
视频可从相机胶卷、iTunes文件共享或直接从相机导入。
支持横向和纵向显示。

常问问题

Q : Can you explain how to use the application?

The goal of the Subliminal Video app is to change some specific images of a video.
First, see the (old but still relevant) video in this page that goes through the main features of the app, and that will show how to use it.

Here are the basic steps :

The Video Selection screen allows to select the input video. The videos displayed are the ones located in the photo app. Swipe up/down to view more videos.
You can swipe to the left or right to view more specific videos.
For instance, videos Located in the iTunes File Sharing can displayed (the videos that you can add in the Subliminal folder using iTunes).
You can also directly record a video, using the top right button.
Touch the video you want to modify to go to the Video Modification screen.

The Video Modification screen allows you to see all the frames of the video.
Swipe up/down to view the images in the video, one by one.
Move the slider at the bottom to have a quicker scroll.
Long press the arrows, at the bottom, to show the next or previous frame.
You can press the bottom play button to play/stop the video. (while playing, touch the video to view it full screen).
When the video is not playing, Touch an image to display the Image Modification screen

Tip: While using the bottom movie scrubber, you can slide your finger from the bottom to the top for higher precision.
Tip: Long press the arrows, at the bottom, to advance or rewind the video frames by frames.
Tip: While the video is playing, long press the arrows to fast rewind or fast forward.

Thanks to this Image Modification screen you are able to modify the selected frame.
There are a lot of things you can do like adding a photo, some text, displaying some color or another image of the video.
You can see the modifications in real time since the updated image is displayed in the top part of the screen.
Once done, you have 4 possibilities :
- delete the modification (using the dedicated button at the bottom part of the screen), if you don't want this modification anymore and want to keep the original frame intact.
- clone the modification (using the dedicated button at the bottom part of the screen), if you want to apply this modification to more than a single frame (the one you selected). Cloning a modification can be useful if you wand to see the modification for a longer time in the video, since one single frame display will be very short (although this is the main point of a subliminal video)
- delete all the clones (using the dedicated button at the bottom part of the screen), if you want to revert all the frames that have been modified with similar modifications.
- accept the modification, by pressing the top left back button of the Image Modification screen.

You will then go back to the Video Modification screen, and the changes you performed in the previous screen will then displayed.
When a frame has been modified, it will be surrounded by a white border. If needed, you can select it again to update or clone it (or delete the modification).
You can press the bottom left/right arrows to quickly go from an already modified frame to another modified one.
You can modify as many frames as you want.
Once all your modifications are done, you can press the top right Export button of the Video Modification screen.

Going to the export screen will generate the complete movie including your modifications.
This generation can take some time, according to the performances of your device.
Once generated, you can view the result and you can export in different ways (using the dedicated button in the list), but the most common one it to the Camera Roll.
(if needed, you can also export the movie to your iTunes File Sharing Subliminal folder)
If you want, once exported you can click on the top left back button (two times) to select another video, and to create another Sublimial Video.

In all screens, pressing the top left button will go to the previous screen.
You can rotate your device, if you want. Some videos are more adapted to a landscape orientations.

Q : The app is taking a lot of disk space. Is there a cache cleaning function?
The app does not really cache any data.
There are only 2 cases where some video data will be stored in the application (making it use some space on the device) :
1. Instead of opening an existing video that is stored in the Photo app of the device (Photo or Camera roll folder), the user imports a new video :
  - by using the internal recording screen of the app.
  - by opening a video from another application into the app (using the Open-in iOS feature).
  To avoid loosing this input video, it is saved temporarily in the document folder of the app.
  This temporary video will be automatically erased as soon as another video will be opened in the app.
  
  So if you have recorded a very big video, and you need some disk space as soon as possible, just open another existing video, when you have done with the recorded video.
2. The iTunes File Sharing folder has been used by the user :
  - to import a video from his computer.
  - to export a video to his computer.
  Once the video is not needed anymore, it is up to the user to delete it manually (using another time his computer).
  
  In case the iTunes File Sharing folder was used unintentionally, and the user wants to remove the files contained in it, without using his computer, he can, as a workaround, un-install and re-install the app.
  This will have the effect to reset the app content (including the iTunes File sharing folder).
For information, the temporary video mentioned in the 1^st part is stored in the same document folder which is accessible through iTunes File Sharing.
Note: This folder will be backed up by iCloud, if this option is activated in the iCloud general settings.
Q : The videos in my Camera Roll are not accessible. How to solve that problem?
You must go to the Settings application -> "Privacy" -> "Photos", and set the app (Subliminal) to ON.
Q : The videos imported from my computer are not accessible. How to solve that problem?
The videos you have imported are most probably located in the Video app of your device (and taken from the Movies folder in iTunes).
Unfortunately, Subliminal Video (and every other app from the Appstore) cannot access those videos in the Video application yet.

The only videos accessible are the ones in the Photo application (the Camera Roll, organized by Events or by Albums)
They are the ones recorded with your camera, but you can also import videos to this Camera Roll from your computer using iTunes, the same way you would import your photos.

Subliminal Video, also supports the iTunes Files Sharing feature, so you can manually add some external videos to Subliminal Video quite easily.
Here is how to copy your videos to the Subliminal folder in iTunes : http://support.apple.com/kb/HT4094
The suggested file format of the videos is Apple QuickTime .mov. Other file formats like .mp4 or .avi files are also supported but might raise some compatibilities issues.
Q : How can I delete videos that have been loaded?
- In case the video to be deleted is located in your Camera Roll, go to the Photo application and you'll be able so see all your videos (and photos).
  Once the video is selected, use the dedicated button to delete it.
- In case the video to be deleted is located in the iTunes File Sharing folder, here is how to access and delete it : http://support.apple.com/kb/HT4094
Q : What video formats can be read?
The video decoder used in the app is the one provided by Apple.
It is able to support all the video formats that are handled by the device itself.
It might depend on the model and iOS version you are using.

For instance, on iPhone5S (with iOS7) here are the supported formats :
- H.264 video up to 1080p, 60 frames per second, High Profile level 4.2 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
- MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
- Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format
