Create a Custom Resolution

You can create a custom resolution by adding a new track. Choose Custom Resolution, then enter the shortest side of the video (e.g. 576 means 576p)

• Choose the option "This track will always be used by stretching its size to fit the width you entered." if you want Stream to upsampling the video.
• Choose the option "This track will be skipped if the video is smaller than the width you entered." if you want Stream to skip transcoding the video that smaller than the custom resolution.
