St. John Virtual Choir



  • Print the provided PDF. If you don't have access to a printer and reading off your screen is too awkward, I can drop off an original.
  • Listen to the provided links below to learn your part.
  • Put on earbuds or headphones and listen along while video recording yourself singing your part (computer or cell phone camera would work fine). Please record in horizontal/landscape mode if possible.
  • Make sure to record video for the whole time, including piano intro and when other voices are singing. This should be just like a normal performance. Don't stop recording until the piano part is totally done. I'll trim off the start/end, so it's better to have too much than not enough.
  • Listen to your final take before submitting to make sure there aren't any technical glitches.
  • Get the video file to me via either the dialog below or email/dropbox/text (907-575-1711) — whichever is most convenient to you is fine with me.
  • You are welcome to submit videos for more than one part, in whichever octave works for your voice.
  • If you're unable to record video but can do audio, I'll be happy with just that along with a picture of you.
  • If you have a problem with uploading big files, consider reencoding with HandBrake or similar to shrink sizes down considerably. Low resolution is fine for my purposes since your video will only take up a fraction of the screen. This could mean 25MB instead of 600MB!



  • Print the provided PDF or read from your screen.
  • Put on earbuds or headphones and listen along while audio recording yourself speaking.
  • Get the audio file to me via either the dialog below or email/dropbox/text (907-575-1711) — whichever is most convenient to you is fine with me.

  • If you know of someone not in the choir who would like to join in, by all means invite them — all are welcome!

How it's done

For those that are interested, I thought I'd outline the process I'm using to put together the final video for the choir.

I find I get the best results if I combine audio and video seperately — that way I can easily adjust levels and make little corrections.

I use audacity for editing the audio. As the master track, I'll open the piano part. I drag all the submissions into audacity — the latest version imports videos as well as audio files just fine. First off, I look for any tracks that clipped (got too loud), and run them through a clip-removing filter to repair them. To get a good starting place on unifying the loudness of the tracks, I run through this filter (it makes the RMS volume the same for all the selected tracks). Now I zoom into the first 30 seconds or so and start lining up track with the piano part. The piano track gets solo'd, then the first submission. I delete or copy/paste audio from the beginning of the submission as needed, If there are a few noisy spots during this silence, like paper rustling or throat clearing, I'll make sure they get removed. If there are noisy bits during rests in the middle of the track, select that and use the Generate->Silence tool to clear them out. Now solo the next track and repeat the procedure. When all the tracks are in place, I select the silence from the beginnig of all the submissions and apply the Fade In effect. Likewies, I apply a Fade Out to the end of the tracks. Listen through, and adjust the balance on all the tracks so none of them stand out. While listening, keep and ear open for barking dogs/other noise, or bad entrances/cutoffs, figure out the offending track, and and use Generate->Silence on those bits. Select the audio from all the submissions, and use the Amplify effect to bring them down 10 or so decibles to bring into balance with the piano. Finally, export the whole thing.

For the video portion, I'm using OpenShot. I'll import all the video files, putting them in thier own tracks. The layout depends on how many submissions there are — I normally end up with three rows of five to seven. Three rows mean they all get Scale X and Scale Y of 33% (vertical videos may need special treatment). Most of the videos will have the same crop width (3 rows divided by the number of videos in a row — i.e. 42%, 50%, or 60%), although videos with different aspect ratios will need to be adjusted to match). Center the singer in their video with Crop X. Location Y will be -.34, 0, or .34 (for three rows), and Location X will have to be manually tweaked to get the videos in the correct layout. Now the master audio track made previously is added. All these tracks are set to display their waveforms so they can be easily lined up with the master audio track. I find it easier to do one row at a time so my computer doesn't have to render so much at once. Disable the audio from the video tracks, and play back and watch mouths to be sure they match the sound. After verifying everyone is lined up correctly with previewing, I'll Snip out the beginning and end, add a quick Fade to the begging and end, then export as the final video file. I've noticed the audio can get a bit garbled — having all these combined audio sources seems to be tough on the compression algorythms, but there's an option in the export dialog to use a higher bitrate for audio that fixes the issue. Reencoding this video with HandBrake gives a smaller file size before final uploading, but I like to change the audio codec to AAC Passthru to avoid introducing new compression artifacts.
