Playback Options 

To access the Playback Options window, launch V1 Pro then select Options. Select the Playback tab: 


If you select the Begin slow motion when a new video is opened option, a video will enter slow motion as soon as you open it. This does not apply to video opened in Compare Mode. 

Skip every other field during slow motion. On slower and/or older systems, you may notice that slow motion is a bit too slow. When you select this option, V1 Pro will skip every other field of video in an attempt to “speed up” slow motion. 

The Draw directly to desktop in RGB format (no overlay) option applies to fullspeed playback. Normally, the system uses a “video overlay” (not to be confused with V1 Pro feature of the same name) in order to efficiently display playback with the highest possible quality. However, on systems configured to use external video displays and/or DVD recorders, this may result in the appearance of a black or pink screen on one of the two displays or the video output. When you select this option, this black or pink screen is avoided at the cost of some video quality (especially on slower/older systems). 

The No MJPG field reverse option applies only to video recorded using the MJPG video compressor. The MJPG compressor is used for Legacy VfW (Video for Windows) capture devices, and some DirectShow drivers, but is not used for DV video captured using a DirectShow driver (details discussed in the Live Video Options section). If your recorded video exhibits a behavior where the video is fine quality, except that the video appears to step forward two, then back one, forward two, etc., then your system might require this option. 

NOTE: Changing this setting will not fix existing video. Its effect will only be noticed with video recorded after the setting has been changed. 

Smart De-interlace (SDI): This is a video quality enhancement technology which increases the apparent resolution of the video in areas without motion (such as most backgrounds). This technology works best with adequate lighting and when using a tripod. Here’s a comparison: 

 Without SDI

With SDI 

You will notice more “stair casing” and other video artifacts without SDI enabled. Notice the stair casing on the mountain without SDI; and the relative clarity of the tee box in the image with SDI. 

If the majority of your video is shot with low-light or without a tripod; however, you may want to disable this feature by visiting the Options/Playback page and unchecking the appropriate box. 


The comparison section of the Playback Options page contains options which affect Compare Mode (discussed above).

In Compare Mode, the two videos may be viewed side-by-side or “stacked” and viewed top-to-bottom. 

The Use key frames to synchronize video tempo option affects slow motion when both videos are selected by causing the faster video to be “slowed down” to match the tempo of the slower video.
