• Network speeds seldom work 100% efficiently. For example, a WiFi G network under
good conditions can frequently max throughput out at around 20-30 mb/s even if the
reported connected speed is 54 mb/s.
Advanced Output Controls
• Screen Size—The video width and height control the size of the video. If you place "0" values for
both height and width, the source video's dimensions will be used for the output file. If you choose
a specific resolution, you should not feel obligated to create output videos that exactly match your
desired viewing device. For example, if you have a TV that supports 1080p there is no strict rule
that states you should convert videos to match this resolution.
Videos are upscaled when the output resolution is greater than the source material; however, the
quality of this upscaled copy varies a great deal depending upon the source material. That is to
say, a source video that is of poor quality or is very small in display resolution seldom looks
pleasant when upscaled to a 1080p screen size. As rule of thumb, if the source material is of good
quality, you should be able to nearly double the display resolution and only see minor issues.
Also of note is that some smaller devices only support a limited display resolution. You might
need to check device documentation for supported video resolutions.
• Video Frame Rate—The video frame rate effects how smooth a video plays and how good the
video quality is within each frame. Choosing a higher frame rate will create a smoother video, but
may increase the need for a higher video bit rate. Conversely, a lower frame rate can create a more
jumpy video, but each frame may look more crisp and you might be able to use a lower video bit
rate setting.
• Video Bit Rate—The video bit rate controls the average amount of storage dedicated for a video
as it plays. A higher bit rate can cause network problems, but a low bit rate can create low quality
videos. Staying within the recommended green area may help you determine the best video bit rate
to use. The green area is based on the size of your output video.
