Video Output of Toaster is Hot

Product: Video Toaster Flyer

Platforms: 2000 3000 3000T 4000 4000T

Problem: Video output is too hot

The video output being too hot can be a result of:

1) Improper termination of the Program Output of the Video Toaster card.

Solution: Properly terminate the output with 75ohm terminator or if the monitor they are using has a 75ohm termination switch make sure the switch is on.

If termination is on, but the output is hot anyway, you may need to have the termination level in the device (monitor or deck) checked by qualified service staff. If the termination level is incorrect, even by a small amount, then the output from the Toaster will be hot (One user reported that a level of 76.2 Ohms produced the problem).

2) A signal passing into the Toaster is unterminated. Unless you are using a T-connector on it, each Toaster Input should have termination turned on, on the Toaster Preferences screen.

3) A defect or malfunction of the Flyer BNC (4000) or Flyer cable (2000).

Solution: Replacement of the BNC or cable

4) Video level of the source being used could be too hot entering the inputs, especially if a TBC is being used to correct the source.

Solution: Test input video with a Waveform and vectorscope to insure that input video is proper. Adjust to proper levels.

5) Luma gain is set improperly on source deck or TBC.

Solution: Adjust setting until problem is gone.

6) Horizontal position of video is off, causing active video top be present where the Toaster expects blanking or "back porch". This happens commonly with TBCs that "kick up" the overscan of throughput video.

Solution: Adjust setting to eliminate problem.
