I would like to slow down a clip (slowing both its audio and visual). I am using the "retime" option under "modify." But when i do that, the voice seems to gain an echo, as if one track is going slower, but another is staying at the old speed. help?
MacBook Pro with Retina display, iOS 10.0.3
Slow down voices will make an echo like sound, but strange that you're hearing the original as well.
Could you share a screenshot of the timeline with the clip you want to retime? Is it a compound or multicam clip?
It's hard to say without hearing this particular instance, but 'slowing' a voice recording that has been made in a natural ambience room can have such an effect.
The near instantaneous reflections of sound at normal speed, are stretched out at slower speeds. This can create an exagerrated reverberation (not strickly echo) effect. The space, the room sounds bigger, like the speaker is in a hall.
This might be nothing to do with your issue but I thought I'd mention it.
perhaps the slow down works better if i first separate the audio from the clip?
Is the audio and video recorded from the same device, or separate?
this has happened to me when they both come from the same device.
