Closed 5opr4ni closed 6 years ago

5opr4ni commented 6 years ago

Expected behaviour

Duration of clip should have the correct time reported in OSC and Info.

Current behaviour

When a 25 fps or 50i file is played and has the LENGTH set, the time is half that of the actual length.

Steps to reproduce

Download this file to test it out. https://www.dropbox.com/s/l5hwohse91bibpz/HAP_Alpha_FILLKEY_AUDIO.mov.zip?dl=0

The "HAP_ALPHA_FILLKEY_AUDIO" is 900 frames (36s) long and Progressive 25fps. Info below.

@5opr4ni what mode are you running the channel in? Remember the LENGTH parameter is in channel frames, NOT media frames, so 900 frames in 50p/i is 18s.
