I have a problem with exporting, hoping that someone maybe able to Help.

When I try to export in H.264 I get a video quality that end up like nothing I have ever seen, if there is any movement like a child on a swing, then if you stop the video on a frame it looks like no sharp edges just window blind effect on the person or even title that is moving?

The only settings I have found to work are as shown on the screen shot using Apple Devices etc

Any ideas as to what is going on would be appreciated

Your description sounds as if your video is interlaced. You should not shoot interlaced video if you can avoid it and unless you really need it. Apple devices deinterlaces the video. You can probably change your project properties to progressive to produce non-interlaced output.

Thanks, I'll check my settings
