No sound here either, but I will comment on the video.

I only watched the first minute as it was too long for me. In other words not enough variety! Looks like it has been uploaded for the bride and groom rather than something to showcase what you can do.

The fades to black are completely wrong. If you must work with one camera in the church then arrive early enough to get lots of cutaway shots which can be inserted at appropriate times. In fact you should do this anyway regardless of how many cameras you may have as it can get you out of many tricky situations when it comes to the edit.

I myself many times work with one camera and get plenty of cutaways, which works for me, although as and when I can, I will use a second unmanned camera to make it more interesting.

Keep at it. Hope your second one goes well.

Cheers
