- Q : Can you explain how to use the application?
Here are the basic steps :
In this screen, You can swipe left/right to switch from the camera
roll of your device, the recent videos, the Favorites, the Live Photos and the iTunes File Sharing content.
(videos that you can add in the Video 2 Photo folder using iTunes of the Files app from Apple).
Swipe up/down to view more videos.
Touch the video you want to extract pictures from.
Tip: You can also directly record a new video, or import a specific one, by using the top right import button.
Tip: Video 2 photo can also be launched from the Photo app (or another app sharing videos), as a share extension.
Tip: The previously selected vedeo is highlighted in blue.
You can export the image from here, selecting the desired button.
Generally, you will want to export it to the camera roll (where all your videos and images are stored in the device).
Touch (or pinch) the image to view it in full screen.
Before exporting you can press the top right icon to crop the image.
The "Export multiple photos" button is quite special. it will display a dedicated screen with ehanced features.
Tip: More infos on iTunes File Sharing which is also assessible by using the files app from Apple.
Tip: Touch the text at the bottom of the list, to directly access to the Video 2 Photo part of the Settings application (ans select the metadatas to be added in the exported images, and to some other options).
To crop the image, drag the red bars to the desired size and press Done.
Tip: Press the Constrain button to set a ratio constraint or to cancel your current crop.
You can rotate your device, if you want. Some videos are more adapted to a landscape orientations.
Tip: The application can be used to open video file in every application that supports the Open-in feature, or the Action extension (like the Photo app).
- In this screen, You can swipe left/right to switch from the camera roll of your device, the recent videos, the Favorites, the Live Photos and the iTunes File Sharing content. (videos that you can add in the Video 2 Photo folder using iTunes of the Files app from Apple).
- Q : Are there some settings in the application.
I'd like, for instance, to change the exported images from .png to .jpeg files.
- 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.
- to store some videos using the Files app.
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 : The videos in my Camera Roll are not accessible. How to solve that problem?
- Q : The videos imported from my computer are not visible. 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 2 Photo (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)
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 2 Photo, also supports the iTunes Files Sharing feature, so you can manually add some external videos to Video 2 Photo quite easily.
Here is how to copy your videos to the Video 2 Photo 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. The Files app from apple can also be used for that purpose.
- 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
