Select Hardware Input Parameters
- Capture based on the sensed video format. Note: during DVI input, the DVI output module is turned off to avoid conflicts with EDID codes.
- Store the uncompressed video sequence on the file system or in memory.
- Create the detailed and thumbnail information.
Record ClearView Output
The ClearView Output tab allows the user to record the video sequences currently playing in Viewport A and Viewport B. 3 reasons exist to do this- Record split screen video sequences as a single video sequence so that they can be exported later for offline analysis/viewing
- Record a portion of the video sequence (or split screen video sequences) as a single video sequence so that they can be exported later for offline analysis/viewing. ClearView records the video area with the zoom box, when AOI is checked.
- Record both video sequences as new video sequences after applying spatial alignment, normalization, and window commands. ClearView records the new video sequences to show the user the effect of the adjustments when the Use Metric Adjustments is checked.
Record ClearView Output
Record 1 SDI Input
The Broadcast tab – Record Mode Single Input records the video sequence as sensed on the SDI input. The SDI can be either SDI Input #1 or SDI Input #2 (as set by Config).Record 1 SDI Input
Record 2 SDI Inputs
The Broadcast tab – Record Mode Dual Input records the video sequences as sensed on both SDI inputs. Each video can go to a different library and both must have different sequence names.Record 2 SDI Inputs
Record SDI While Playing
The Broadcast tab – Record Mode Input/Output records the video sequences as sensed SDI Input #2. SDI Output #1 is the video being served. The video format must be the same (i.e. both 1080i).Note: If you want to play to a video encoder while recording from a video decoder. Then set the sync source to SDI #2 (the source) under Config.

Record DVI Input
The Record DVI Input records a single input from the DVI input module. The DVI output is turned off during recording to ensure that frames are not dropped.Record 1 DVI Input
Record Pane Description
| Input | ClearView supports the following Inputs if the Modules have been purchased
|
| Config | Configure is different depending on the Input Source
|
| Record Mode | This only applies to the Broadcast Input Module
|
|
This lets you set the library for recording so that you can change it from the library used for playing |
| To Disk | Checking this button records the input to the file system Unchecking records the input to Memory |
| AOI | If you have zoomed and panned to a particular area. You can record the video sequence in 1 of 2 ways:
|
| Use Metric Adjust | Checking this box will start the process of re-recording the 2 video sequences associated with Viewport A and Viewport B. The video sequences are re-recorded after apply spatial alignment, normalization, and windowing. Note 1: for spatial alignment, the alignment must be an even number to avoid color shifts in Y’CbCr space and/or flipped fields in interlaced modes. Note 2: for spatial alignment, both sequences are moved and centered while performing the adjustment. |
| Sequence | This is the name that is displayed in the thumbnail. Note: this can be renamed later. |
| Frames | Select the number of frames to record in the Record Pane. The number of frames defaults to the maximum number of frames available in memory or on the disk. |
| Abort on Drop | Checking this aborts the record on the first dropped frame Unchecking this allows the system to keep recording albeit with the error frame. |
| Status | This simply says previewing, recording, or nothing. |
| Drop | This increments the number of frames that have been dropped. |
| Out enable | If you are using the Broadcast I/O DL module, then this button will be active. It allows the operator to capture and playout simultaneously.
Note 2: Input is connected to SDI In #2. Note 3: This does not work with the Broadcast I/O AD module |
| Preview | Press this button to preview the record from Broadcast or DVI to make sure that something is connected to the input. Note: In Broadcast Input or DVI Input modes, preview is not active on the preview window once you select the record button. A hardware preview is supplied with the Broadcast and DVI Input Modules. |
| Record | Start the record process. It will automatically end when the frame count is reached |
| Stop | Stop recording |
To record the current ClearView sequence, jog to the desired frame. In the Clip Alignment pane, set the first frame. To record a number of frames, you can either set the last frame in the Clip Alignment pane or you can select a number of frames in the Record pane.
You would want to record the output of ClearView if you intended to:
- Export the video sequences as they are playing side-by-side to an AVI file (or BMP, Raw, etc.)
- Export the video sequence as a smaller version (just looking at the spokes of the wheel as opposed to the whole car).
- Create 2 new video sequences after the spatial alignment and normalization has adjusted the 2 video sequences relative to each other.
Note 1: that if you simply want to hit play and then record, you do not need to set the Clip Alignment. If you want to record just from frame n to frame m, and give it a new name, etc., you need to use a combination of the clip alignment and the record function.
Note 2: Please be in Stop mode before starting the record or you will record more than 1 first frame. (Of course, you can edit these out, using the Clip Alignment pane.) This is because in pause mode, ClearView is displaying the same frame over and over. If you hit record while ClearView is doing this, then it will record that same frame over and over. In Stop mode, ClearView is not displaying, but the last frame that was played stays on the screen. The confusing part is that when you hit play, it will not start at this frame. It starts at the frame number given by the “clip alignment first frame” (probably frame 0).
To record from Broadcast or DVI input, connect your source.
- In Broadcast input mode, ClearView auto senses the video format. To make sure that it has selected the correct format, select the Config button.
- In DVI input mode, a configuration option will pop up as shown below.

Configure DVI/VGA Input Module
If the image dimensions, frame rate, etc. are correct, then click on OK. If they are not, then select the Input tab, and select VESA detect. The following dialog will appear. Press start. If the parameters are correct, then press OK.
Note: If you run into problems, please call Tech Support. To find your local office, please refer to www.videoclarity.com/sales.html.
Use Auto Detect to configure DVI/VGA Input Module
Click on Start to begin, then OK. Now check the image dimensions. If everything look good, click on Apply and then OK.
