Compression size difference with and without Quick Sync Video

Post by parag_ca » Sun Dec 09, 2018 5:22 am

Why my Compression size is more with Quick Sync Video and how to make it equivalent to H.264(x264)
Input file size: 20.2 GB
Video:

Frame width: 1920
Frame height: 1080
Data Rate: 15000kbps
Total Bitrate: 15384kbps
Frame Rate: 25 frames/second
Audio Bitrate: 384kbps
Channels: 2
Audio Sample Rate: 48 kHz

HandBrake version (1.1.2):
For Video codec: H.264 (x264)

Re: Compression size difference with and without Quick Sync Video

The Quality Scales are RF and QP for x264 and QSV H.264 respectively. They are not quite the same scale.
Adjust the QSV one to a higher number to reduce file size.

Note, QSV only supports a small subset of features that x264 does, so typically you'll need to have a higher bitrate or quality level (thus larger file) to achieve similar quality levels.

Re: Compression size difference with and without Quick Sync Video

In my experimentation with QSV, I found that simply changing the encoder on a given preset resulted in about a 5% increase in size for a QSV result. My experiment lasted only a few days - the size/quality advantage of x264 vs qsv_h264 convinced me that I'll spend the CPU cycles, and let handbrake finish when it finishes.

How long it takes for handbrake to finish is less important when you're not waiting on it to queue the next encode. :)
