I had someone send me a video presentation via webcam ( .mov format),
however the speaking was a little bit behind the mouth moving.
Is there a way to correct this video? And is there a way to avoid this on future ones?
Thanks
It can depend upon how they encoded the video and how good their hardware and codec plug-ins were, etc. If the video plays bad and you have a good computer (with good up-to-date codecs) then you cannot do much.
As obviously it was probably caused during the recording process at their end. You possibly could do editing of the sound track if you have the tools but I’m not sure how that would work out.
