I just bought the HEVC codec so that I could use apple film on magix but the video does not show up. i can hear sound but there is no video. What am I doing wrong. Thank you.
Hi,
Probably you have to download and install the free Windows HEVC codec from Windows web site also install the HEIC codec. Before install the last Windows 10 update.

Possibly nothing wrong. The problem is if you are recording HEVC with a variable frame rate. On iPhones this can be switched off I think on the phone. For any other files you may have already, you made need to convert them first to constant a frame rate before most editors can handle them. To find out if the file is variable frame rate of not, download the free MediaInfo program (Link in blue) and see what the file readout says. Use the 'Tree View' and it will give all the details. If you don't understand the results from MediaInfo then post them here for us to look at. To convert variable frame rate files to constant frame rates you will need another program. One called Handbrake would do. Then that file can be used in your video editor. Variable frame rate recordings are still relatively new and designed to save memory space on your phone. Unfortunately the decoders don't seem to have made their way across to other editing software yet. This could be a deliberate holding back from the phone manufacturers.

Interesting. I just tried to import a video from my daughter's new iphone 11. MEP put up the message about buying the HEVC codec, which I did (US$5). I activated it, then imported the video no worries. Mediainfo gives the framerate as Variable "mode" ( I notice it shows overall framerate as 29.97):

Cough cough splutter splutter, short answer, No, sorry about that! 😂. I gave it a quick play and it looked OK, but on closer examination (dragging play marker thru), it's jerky. I Handbraked the clip (had to set the framerate) and that one is smooth.
Hi Alwyn
. . . . Cough cough splutter splutter, short answer . . . .
That is exactly what the program is doing 😂😂 - trying to determine which frames it should be 'regenerating/creating', it may have to go back many frames to find the last I frame and then work forward again recreating the 'missing frames' where the frame rate has dropped, continuous playback should be smooth as it looks ahead and caches complete frames of video ready for display at the appropriate time.
