YesLaw Online

A streaming video quality question.

YesLaw answers a user question about picture resolution for the Online experience. YesLaw Online creates multiple files in two formats Flash for PC users and H.264 for Apple users. These formats are also created at various bit-rates to match the connection speed as detected when the user logs in. This user question is about HD which is not widly used in legal applications but the answer contains general streaming information.

Q: If you compress HD down to something that can stream in YesLaw or on the Internet through YouTube, does it become standard definition by default as the resolution changes?

A: Available viewing format is dependent on two factors the quality of the uploaded original and the connection speed of the user.  HD will down convert to be delivered at lower quality when delivered on a low bandwidth connections. The YesLaw Online site determines the best bandwidth for user connection which is automatically “sensed” and streamed out. On YouTube a user can override the initial playback bit-rate in the bottom right corner of the viewer but if you do not have the connection speed the viewer experience will be herky jerky due to delivery of less than 30 FPS. YesLaw does not give the end user the ability to override the bit-rate of a video deposition stream which avoids the delivery of a herky jerky file.

YesLaw and YouTube will not up-convert SD frame sizes and bit-rates to 16X9 with the higher HD bit-rates. A user will be limited in the highest quality available for viewing by the quality uploaded. Rule-of- thumb: upload the best quality you can so the viewer will receive the best quality their connection can handle. If they have the bandwidth they will enjoy the higher quality picture. At slower connection speeds they will still receive an acceptable playback experience but at lower resolution. YesLaw accepts video uploaded in the MPEG1 or MPEG2 format, both formats are converted to streaming optimized file formats. The only downside to uploading the higher quality MPEG2 file is the time it takes to send the larger file over the available connection.  YesLaw has no practical limitation for incoming file connection speed, the limitation is from the send side only.

The final comment/observation is: If you must upload low quality/low bit rate video, just stand far enough back and it will look good.
