Some video files will import into K on my Mac & play fine, but won't play on my iPhone
iPhone SE, iOS 14
Thanks! I checked all files & they are H.264 .mp4 file types. The really odd thing is that some will play fine & others will play audio only, but not the video. All files function perfectly on my Mac.
Good to hear you have a result
The files were purchased from an individual who creates and sells these for public presentation. File sizes range from 1.2Mb up to 20Mb.
Reading the Apple support info & other sources, I converted the files from .mp4 to .mov format which worked perfectly. The presentation now plays perfectly using my iPhone.
The iPhone supports the following filetypes for playback:
iPhone Supported Video Codec: H.264, H.265, MPEG-4,
iPhone Supported Video Container Format: .mp4, .mov, .m4v, .3gp
How are these files made or imported from?
What is their pixel size?
Because the The Video container used as:
.mp4, .mov, .m4v, .3gp
