Both cameras are a good choice for a camera.

But........

Neither is outstanding for video.

The LS743 video is 640x480 at 13 fps (frames per second).
The A75 is 640x480 at 15fps and is limited to about 2 minutes for each shot.

For flicker free video you need 25 to 30fps.

.........................

For your target price range, I would start looking at the:

Nikon 5900 (about $260): 5 megapixels - video 640 x 480 at 30fps.

Note: If you see the less expensive Nikon 4600 or 5600, be aware that the video for those 2 cameras is 640 x 480 at 15fps. And the 4600 has no sound.

The Nikon 5900 is getting great reviews and it takes excellent photos.
