240 FPS iphone clip length issues changing frame-rate or speed
An user reported that the 240FPS clips from iphones are wrong managed by Kdenlive ( MOV format ) i downlaoded a sample.. and seems that something is wrong, the final lenght on seconds of the processed file is not correct.
here a video about che frame change (properties)... the frame rate is right (on a 30fps project) .. but the lenght is maintained at 19 seconds like original footage and not something like 150 seconds...
and also trying to slow down the clip to 12.5% (to have a correct slow motion effect on a 30 fps project) is creating a shorter video of 15 seconds ... (but slowed down)
i tried also slowering the clip.. and in 1 case i was able to slow down to 12.5% without issues... (?)
the original clip is here: https://drive.google.com/file/d/1ODbGkogJMET1b5YChs43RSh94Tz52no0/view?usp=sharing
using the default speed change (form timeline) works without issues...
