We have a percussion video along that features a percussionist playing with a DJ.
They pre-recorded the audio of the percussion, which we have stems for, and have applied this to the edited video, however unfortuantely what they are playing on the video doesn't totally match the audio they pre-recorded.
We have stems of the percussion that you can use to edit, but we need you to edit the audio so that it matches the video, and still sounds good.
In addition to that we need the audio stems to be mastered and EQ'd so that the percussion sounds better.
Finally we need the track to end in a way that feels a bit more concluded. This might be a Sound Effect or cutting the final note.
here is the video with the sometimes misaligned audio:
