介绍
Video Crop & Zoom使你可以轻松准确地裁剪视频。
用途：
- 需要从视频中删除一个人或对象。裁剪视频可让这部分不可见。
- 拍的视频是纵向的，想改为横向。
- 想给视频添加一些特效，如放大某人脸部，或缩小看更大的视图。
- 想保留视频最佳部分，裁剪主要部分及去掉多余的。
- 在发送到电视或喜欢的社交服务前，想按特定规格裁剪（方形、4x3、16x9...）。
可识别事件和相簿。
还可将你的i设备连接到iTunes以拖放其他视频（使用iTunes文件共享功能）。
动态的原创用户界面使你可以根据需要裁剪视频的每个画面。
将在每个修改之间自动完成插入，以逐渐缩放并移动到裁剪区域。
可以使用一些简单的手势来定义这些裁剪区域，但是如果需要一些高精度，您可以直接更改值（以像素为单位的大小和位置，以角度为单位）。
可以显示一些可选的可视指南，如可配置的网格和上下文信息，以帮助您跟踪目标。
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。
此应用程序可以运行，在你的iPhone和iPad上，作为一个独立的应用程序，或作为行动扩展（从像照片应用程序的兼容的应用程序）。 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 : 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) :
-
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).
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.
-
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.
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 1st 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.
-
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 :
- 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
-
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).
- 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
