Using Kdenlive 24.12.0 for Linux.
When I add an MP4 clip from my iPhone 16 Pro to Kdenlive, I get a pop up window which states:
“The following clips are not usable for editing. This will transcode them in an edit friendly format and replace the original ones in your project”.
The window has a button on the bottom labeled ‘Transcode’. When I click it, I get an error message in the clips window saying “Failed to create file”. When I click on 'Show Log" I get
[aist#0:2/none @ 0x57fab471e5c0] Decoding requested, but no decoder found for: none
[aost#0:2/aac @ 0x57fab483a380] Error initializing a simple filtergraph
Error opening output file /home/jim/IMG_3792-60fps.mp4.
Error opening output files: Invalid argument
It seems there is no decoder to transcode the clip… Does anyone know what ‘decoder’ is required to transcode my iPhone clips and if so, how do I install it?
Note, that despite the error, I can still use and edit the clip normally… And I read variable bit rate on the iPhone can be a problem. I’ve turned it off, but I still get the error.
