Settings

• The auto white balance can be very noticeable and can cause color shifts with black and white film.
• It is best to manually calibrate it before every recording.

1. Click the white balance tab.
2. Set the white balance to OneShot. This sets the calibration.
3. If you adjust the exposure setting on the projector you might need to recalibrate the white balance.

Threading the Projector

4. Push the autoloader
5. Trim the film if needed.
6. Put the film on the supply reel arm.

8. When there is enough film to wind onto the take up real,turn off the projector and thread onto the take up reel.
9. Pull the film to make sure the autoloader is off, there will be a click.

• If the take up reel does not move:
  • make sure that the autoloader is disengaged
  • there might need to be more film/leader on the reel

Recording

Capturing

1. Go to Capture > Video Capture.

6. When the film is done turn the projector off.
7. Click the X in the top right of the window to stop the recording.

Watching the files

• You can open the file in VLC to watch it but the motion will be a little fast.

More Recordings

• You might need to record multiple passes with different exposure settings.
• Re-calibrate the white balance before each recording.

Rewinding

• Running film through the projector in reverse does not work very well.
• It losses the loop and tends to jam
• It's best to run the film forwards all the way through the projector and do a fast rewind.

1. Running the film through the projector.
2. Thread the film straight across the top of the projector.
3. Set the projector to Reverse and press the Rewind button on the projector.

• Each recording needs to switched to playback at 24fps.

1. Open AVIFrameRate from the desktop.
2. Click the folder icon and select your video
3. Set the New Frame Rate to 24.000 and click Apply
4. Click OK to close the new window that will open.

• Now if you watch the clip in VLC the motion should be correct.
• You need to do this to all of the video you recorded.

Converting the Video

2. Drag a video into the Queue window.
3. In the Preset Browser click System Presets > Broadcast > H.264 and choose HD 1080p 23.976 or HD 1080p 29.97

Copying the Files to the Network

2. Go to search and type in \\orca and press Enter on the keyboard.
3. On Orca navigate to the Programs folder, and find your class folder.
4. Copy the files to Workspace or into your cubby.

* Make sure to copy the original avi files and the converted mp4 files.

Troubleshooting

• If the video looks "smeared" check the Trigger and IO settings.
• If StCamSWare stops getting picture check the Trigger and IO settings.
• If the image has a green tint or exposure shifts make sure to manually set the white balance with One Shot.
• If the image looks "jerky" make sure that the auto-thread is disengaged.
