Video Crop & Zoom

프레젠테이션

Video Crop & Zoom allows you to crop your videos in an easy and precise way.
Why would you do that?

You want to remove a person or an object from a video. Crop your video to make this part invisible.
You need to straighten a video in order to fix the horizon.
You have recorded a video with a portrait orientation and you would like to change it to a landscape orientation.
You want to add small effects to your video, like a zoom-in to someone's face, shortly followed by a zoom-out to a larger general view.
You want to keep the best of your video only, cropping the main part of it, and removing the superfluous.
You want to crop your video with a specific constrain (square, 4x3, 16x9 , ...) or some precise dimension (580p, 1080p, ...) before sending it to your TV or your favourite social service.

Videos can be imported from your device in different ways.
You can also connect your iDevice to iTunes in order to drag and drop other videos (iTunes file sharing feature).

An animated and original user interface allows you to crop (and zoom and rotate), if necessary, every frame of the video independently.
An interpolation will be done automatically between each of your modifications, in order to scale and move progressively the crop area.

Those cropped areas can be defined by using some simple gestures, but in case some high precision is needed, you can directly change the values (in pixels for the size and position, in degrees for the angle).
Some optional visual guides, like configurable grids, and contextual information, can be displayed to help you track your target.

You will find the original and intuitive user interface, common to all our videos applications.
These applications have been featured many times by Apple and various websites.

This application can run, on your iPhone and your iPad, as a standalone application, a Photo Extension, or as an Action Extension (from the compatible applications like the Photo app).
Videos can be imported from your device in several ways.
Portrait and Landscape orientations are supported in all screens.

자주하는 질문

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 : I'm on iOS8.0 (or higher), and the application does not display most of my videos. Why ?
It is highly possible that you have ICloud photos enabled on your iPhone.

ICloud photos automatically moves your old photos and videos from your camera roll to the cloud. Your camera roll (Recently added) containing only your most recent videos (and photos).

The app displays the videos that are in the camera roll, this is probably only a few videos can be seen.
Here are the possible solutions :
- In the photo app, you can download back a video from the cloud to your device (in the camera roll).
- Adding a video to an album in the photo application of your device, should permanently keep the video in the device. The app can display the videos in your albums if you swipe to the right, once in the video selection screen.
- Alternatively, the app can be used as an Extension, so you can launch it directly from the photo app, with any of your video selected.
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 (Crop & Zoom) 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, Video Crop & Zoom (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.

Video Crop & Zoom, also supports the iTunes Files Sharing feature, so you can manually add some external videos to Video Crop & Zoom quite easily.
Here is how to copy your videos to the Crop & Zoom 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
