Lecture Recorder x2 User Guide 3-2 Fine-tune channel configuration Upscale or downscale your video image If your source input is larger than your desired output frame size or if you want to stream a less bandwidthhungry version of the content, you can downscale the source by specifying a frame size that uses the same aspect ratio. By contrast you can also enlarge the image by selecting a value that is larger than the source resolution.
Lecture Recorder x2 User Guide 3-2 Fine-tune channel configuration 6. Choose a resolution from the links on the right, or type a frame size into the Frame size fields. 7. Click Apply. The final frame size can be larger when Picture in Picture layouts are used. Control the matte (black bars) in the video output By default, the Lecture Recorder x2 makes sure that the aspect ratio of input signals is preserved when the output is streamed.
Lecture Recorder x2 User Guide 3-2 Fine-tune channel configuration For example: l Input signal resolution is 720×480 (a 3:2 aspect ratio) l encoded resolution is 1280×800 (a 16:10 aspect ratio that is wider than the input resolution) Borders are added to the left and right of the image to preserve the narrower ratio of the input. The left and right side border are not guaranteed to be of equal width.
Lecture Recorder x2 User Guide 3-2 Fine-tune channel configuration 6. Look for the source aspect ratio in the list of aspect ratios provided. a. If the source resolution is on the list, choose another resolution on the same line (i.e. with the same aspect ratio). b. If the source resolution is not on the list, use a calculator to get a factor of the source resolution and enter it in the Frame size fields. 7. Click Apply.
Lecture Recorder x2 User Guide 3-2 Fine-tune channel configuration Unstretch the output video By default, the Lecture Recorder x2 makes sure that the aspect ratio of input signals is preserved when the output is streamed. If this default was overridden or if the channel was created in a version of the software earlier than 3.11.0, the image is stretched to match the output frame size. The effect may be subtle and may not be problematic for you, but if you want to resolve this it is very simple to do.
