Charles,

If Squeeze is optimized for the Sorenson 3 codec it doesn’t really show. I’m running a Dell PowerEdge Xeon Dual 2.8 GHz. A 10 minute video that’s encoded using Squeeze’s Sorenson 3 codec takes about 26 minutes. The same video using Cleaner XL encoding takes 8 minutes. Go figure. 8)

I agree their 1.5 upgrade charge is a bit of a rip-off, but one big advantage Cleaner XL has over Squeeze is that it’s optimized for multiple processors. Encoding is way too slow on Squeeze.

Hi Charles,

I’m curious when you say for QT encoding you’d use Squeeze for the PC, do you mean QT Sorenson Video 3 encodes? From my tests Cleaner XL does better Sorenson QT video quality than Squeeze using the same bit rate.

Ben,

So if I have a fixed bitrate than the file size should remain the same regardless of the number(frequency) of keyframes?
I’m using 2 pass VBR and the same bitate. These are my test results:

FLV 10(fps)
1,626,514 bytes — keyframe every 10 frames
1,626,955 bytes — keyframe every 20 frames
1,627,166 bytes — keyframe every 50 frames

QT 15 (fps)
2,955,391 bytes — keyframe every 15 frames
2,712,897 bytes — keyframe every 30 frames
2,831,045 bytes — keyframe every 75 frames
2,871,357 bytes — keyframe every 150 frames
