LG KU990 Viewty Review: Eyes Wide Open: Video - Slow Motion And VGA, Conclusion

By 08:11 Sun, 08 Aug 2021 Comments


Video is on par, too

LG KU990 is meant to be a revolution with its video recording capabilities. All the video recordings are stored in AVI file format with DivX 5.0 encoding. This ensures fine balance between file size and quality and is remarkable amongst cameraphones. The camcoder supports capturing video in Video Graphics Array (VGA) resolution at 30 fps (the "DVD-like quality" as advertised by Nokia), but that's not all. At QVideo Graphics Array (VGA) resolution the framerate can soar up to 120 fps!

When we first heard that the newly announced Viewty will be able to shoot video at 120 fps we thought it was some kind of a mistake. After all, most digital cameras and camcorders nowadays will only go up to 60 fps. As it turned out, the 120fps were for real. Why should we need such speed, you may ask, when the fine recent 24 frames is what gets people crowding the movie theaters. Well, the 120 fps mode is meant for slow motion movies. LG calls the mode QVideo Graphics Array (VGA) QVS and while the capture occurs at 120 fps, the resulting AVI file is stored at 15 fps slowing down the recorded action 8 times.

Doing the math, it turns out that these 120 fps at QVideo Graphics Array (VGA) are not that demanding on the processing power. The amount of pixels processed per second is exactly the same as with Video Graphics Array (VGA) 30 fps movies. As you may see from our samples, a 120 fps video recorder can be real fun and it's strange that no other manufacturer (digicams included) has implemented it so far.

When shooting at 120 fps a lot of light is needed. It's easy to understand, since the shutter speed for each separate frame should be no slower than 1/120 sec, even if we don't count the added time for processing. Keeping the shutter speed as quick as 1/120 sec indoors, for example, can be done only with significant ISO boost, which of course will result in worse quality. So, to summarize, good-quality slow motion movies will be possible only with a lot of light and this is not the device's fault.

Have a see at our 120 fps samples. We've used VirtualDub to adjust the playing speed of the 30, 60 and 120 fps samples, the 15 fps version is the original one produced by the KU990.
