Have you ever run into this weird situation when you try to make a FLV video file with Adobe Media Encoder and when you try to resize it the encoder changes the dimensions you entered? No matter what you try you don’t get the desired dimensions.

Once I was in this same situation when I found that:

1. When you use export to FLV the codecs used support only even numbers for dimensions;
2. In fact, VP6 codec and some others suffer when their dimensions aren’t divisible by 16;
3. This causes the resultant FLV to have grey lines on top and bottom or on the left and right side;
4. You should keep that in mind and will have to make videos (that you’ll convert to FLV) using even numbers for their dimensions or …
5. Make your videos the desired dimensions and then convert them to F4V with Sorenson H.264 codec and keep their dimensions intact (but it’s better to use even numbers: divisable by 16 for the width and divisable by 8 for the height!).

Hope these lessons help you make your life easier when working with FLV. Good luck!
