Many popular encoders on the market use variable bitrate encoding.Attempting too high of a resolution on too little processing power can result in degraded image quality and corrupted or interrupted streams or recordings. Be aware that higher resolutions require greater processing power to encode the stream.You will have no gain in quality and you are using more bandwidth than is necessary for you and your viewers. For example, it does not make sense to capture at 720 and stream at 1080. You should never be scaling up and streaming at a higher resolution than your original video source.Or capture at HD 720 and stream at 540 (high). For example, capture at HD 720 and stream at HD 720. It is best to either match your original video source, or scale it down.We recommend streaming at a resolution with a 16:9 aspect ratio as listed above.The table below provides recommended configurations for higher and lower bitrates and resolutions.
Qualityĭepending on your video production workflow, your encoding equipment, or your available bandwidth, you may want to send lower or higher resolutions and bitrates or you may want to send up to 4 multiple bitrates instead of using IBM Video Streaming's Cloud Transcoding option. Attempting higher resolutions and bitrates without sufficient encoding resources or bandwidth can lead to poor image quality and interrupted or corrupted viewing or recordings. These resolutions should only be used when you are certain you have sufficient resources to successfully encode and send with no quality loss. For most applications IBM Video Streaming recommends sending a single high definition stream at 720p resolution with the following settings: Qualityįull HD 1080P and 4K streams require significantly more encoding processing power and bandwidth.
