Bitrate question

Hello Support team,

I have downloaded one of the 'Bigbuckbunny' mp4 trailer in order to compare it with my encoded video.

I encode a video of size 1024 x 768 30 FPS captured by camera and set the bit rate to 16000 (16 kbps) to get a decent and non blocky mp4 (even

if there is no movement in the scene captured).

The 'Bugbuckbunny' mp4 is 1280 x 720 25 FPS and encoded only at around 1600 kbps with smooth video (1/10 bit rate of my video).

What might the reason for such difference in the two bit rates? for same length, I need 10 times the bitrate to get relatively smooth video.

Many thanks,

Joseph

Hi Joseph, 

MediaSDK only supports elementary video streams. Can you please share more details about your scenario like which encoder are you using to encode input clip? Are you using HW/SW encoding? Also, the application you are using (if sample_encode without any changes "https://software.intel.com/sites/default/files/MediaSamples_Windows_6.0.0.68.msi")? In addition, please share a log from system analyzer tool (https://software.intel.com/en-us/articles/media-sdk-tools), which can help provide us your system environment details like OS/Driver/platform version.

Thanks,
