ipad video no picture when exported to pc

[cyflyer]

Hi guys, its been a while. Updated my ipad to a more recent version, gen 9/2021, videos look fine on the ipad, but when exporting to pc, there is no picture, only the sound. Some googling told me that Apple changed the .MOV format to a more compressed version that is not compatible with the pc player (grrrrrr), and you have to change the camera settings on the ipad to 'most compatible', however, no explanation on how to convert video you have already filmed on the ipad, how to convert them. Anyone come across this ? Converters such as Handbrake don't recognise this file format. TIA

Sounds odd. Try opening the file in VLC Player. If that won't open it, give us the Mediainfo report; go to Text view (View menu>Text) and copy all the report text and paste it here.

I found this on a site for 'Photosynch', so I understand what has happened now, Apple screwing around the format, but trying to salvage some video I shot already with having to buy another app.

iOS 11 and macOS High Sierra introduced support for these new, industry-standard media formats:

HEIF (High Efficiency Image File Format) for photos
HEVC (High Efficiency Video Coding), also known as H.265, for videos
HEIF and HEVC offer better compression than JPEG and H.264, so they use less storage space on your devices and iCloud Photos, while preserving the same visual quality.

When using iOS 11 or later, the following devices can capture media in HEIF or HEVC format. Other devices can view, edit, or duplicate this media with limitations, if using iOS 11 or later or macOS High Sierra or later.

iPhone 7 or iPhone 7 Plus or later
iPad (6th generation) or later
iPad Air (3rd generation)
iPad mini (5th generation)
iPad Pro (10,5 inch)
iPad Pro (11 inch)
iPad Pro (12,9 inch, 2nd generation) or later
Since iOS 12, all new iPhones and iPads record photos and videos in HEIF and HEVC formats as standard. Older devices and Windows PC's often do not have the capabilities to display or play these formats. With videos, for example, this means that the sound track may work but no picture can be displayed. Because the HEIF and HEVC files are usually much smaller than the JPEG or H.264 versions it is a common misconception that PhotoSync transfers the files in low quality.

To continue capturing media in older formats that are more compatible with other devices and operating systems, perform the following operations on your iOS device:
Go to Settings > Camera.
Tap Formats.
Tap Most Compatible. This setting is available only on devices that can capture media in HEIF or HEVC format, and only when using iOS 11 or later.

HEVC (or H265) is a widely-used video codec. Fairly new, but with good support. Any decent PC player (inc VLC) and recent TV will be able to play HEVC files. I doubt that that is your problem.

I use Photosync; it is freat for moving "i" video files from and to your PC. When set up, the best part is it renames the file with the date and time and retains the correct date data in the file when transferred to the PC, something which in my experience doesn't happen if you simply drag and drop files using Windows Explorer.

Get the data from Mediainfo and post here. Something's awry.

Thanks Alwyn. It was as per the info above. HEVC may be widely used, however when exported to pc with the default setings on the ipad/iphone there is a compatibilty issue. The settings have to be changed to most compatible in the device, and the existing videos I exported and when doing that the ipad gives you option of exporting with a 'most compatible' setting. They transfered ok afetr doing that.

however when exported to pc with the default setings on the ipad/iphone there is a compatibilty issue.

Curious, how are you "exporting" them to the PC?
