How to calculate the time offset and rotate video on import

Let the wizard work out the clock offset from the real and on-screen times, rotate or change the aspect ratio of frames, and choose an FFmpeg version.

Some of the new improvements made to 3.3 have been to the import and the import wizard. We already talked about the video preview in the wizard, so now we’ll talk about the other additions.

Auto time different

The start time page of the import wizard with the Time Difference section expanded: actual time, screen time and the difference.

Working out the actual start time for a video can be a pain. Now if you have the actual time and the time on the dvr or screen you can let Kinesense work it out for you. Expand the Time Difference section in the start time page of the wizard. Enter in the correct time as noted at the time of evidence collection. Then enter in the time that was noted on the screen at the time of evidence collection. The time difference will appear underneath. When you’re happy click Apply and the time difference will be applied to the start time.

Rotate view

The Rotate View tab in the Advanced import options, with rotation and aspect ratio settings.

There is now a new tab in the advanced section of the summary page in the wizard, called Rotate View. Here you can rotate the frames of the video while they are importing so that they appear in Kinesense the right way around.

The Rotate View drop-down listing mirror, flip and rotation options, each with a preview of the letter R.

The rotate your frames, open the Rotate View drop down and select which way you’d like the frames to be rotated. An image showing you what the rotation means appears beside the text.

You also have the option of changing the aspect ratio. Click the check box beside Aspect Ratio and then select the desired aspect ratio. You can currently choose between 4:3 and 16:9. When you’re finished your selections just click Begin Processing as normal and the changes will be applied to your videos as they are being imported.

FFMPEG version selection

The Preprocess Script tab with a drop-down to choose between installed FFmpeg versions.

In the preprocess script tab, you are now able to select the version of ffmpeg you want to use. By default there will be only one version of ffmpeg to choose from. But if you add another version into the FFmpeg folder, C:\Program Files (x86)\KinesenseLE3\FFmpeg, it will appear in the drop down list and you’ll be able to use that to execute your scripts.

Format support

3000+ video formats

Anything playable in Windows Media Player, VLC or FFmpeg is supported, without the manufacturer's original player. Have a format that isn't listed? Our engineers have 17 years experience of dealing with difficult formats.
