Solutions for encoding
Encoding is an art of optimization. Reducing the necessary bandwidth while preserving the visual quality of video contents requires many efforts.
At all stages of encoding optimization (research and development, test and validation, benchmarking and comparison before purchase), measuring perceived video quality of encoded videos is a fundamental task to make progress.
We have the solutions to help you.
First solution: Video Quality Analyzer (VQA)
Video Quality Analyzer (VQA) measures perceived video quality. Its video quality analysis reports are very precise and enable to benchmark and compare video encoders (to choose to best one before purchase) and to optimize video encoding parameters, like bitrate, in order to reach a given video quality level (for the video encoders you have already bought).
VQA can also measure and monitor a file-based encoding process (like encoding for VOD for example).
Second solution: Video Quality Monitor (VQM)
Video Quality Monitor (VQM) monitors audio video quality from live sources, like the output of an encoder.
VQM measures audio video quality from files too.
VQM also includes ultra-fast (about 1000 frames per second) "decodability metrics" which count the number of decoded video frames and decoded audio samples number to check that encoded files can be correctly decoded.
Third solution: : Full Reference Video Quality Monitor (FRVQM)
Full Reference Video Quality Monitor (FRVQM) measures and monitors video quality, audio quality and lip-sync in real time from live audio/video sources: HDMI, SDI, ASI, IP streaming (UDP, RTP, HTTP, HTTPS, HLS, MPEG-DASH, RTSP, RTMP, NDI®) and desktop capture..
FRVQM enables to measure video quality using Netflix's VMAF metric in real time, from live audio/video sources.FRVQM also measures of blockiness, blur, contrast and flatness for both the reference video and the measured video (and audio quality, loudness, lip-sync and delay).
Fourth solution: : Audio Video Sync & Quality Monitor (AVSQM)
Audio Video Sync Monitor (AVSQM) measures and monitors both QoE and QoS.
AVSQM measures and monitors the synchronization between audio and video at one or several locations. Thanks to our proprietary technologies for audio and video fingerprinting, AVSQM is very precise and non-intrusive. During monitoring, all measured data are saved and can be retrived as curves and statistics between two user-defined dates.
AVSQM also measures and monitors video quality and audio quality..
AVSQM measures and monitors the Quality of Service (QoS) concerning transmissions (packets loss, packets delay, jitter, etc.) and concerning machine health (CPU usage, RAM usage, etc.).
