Theora file size
...ora and Xvid files were
made from a y4m file. The resolution is 1280x720:
1. Xvid 17MB
2. Ogg/Theora Q7 31MB
3. Ogg/Theora Q8 38MB
4. Ogg/Theora Q9 49MB
5. Ogg/Theora Q10 61MB
The Xvid file was made using mencoder by 2 passes with
following options:
bitrate=2500:autoaspect:chroma_opt:vhq=4:bvhq=1:quant_type=mpeg:pass=1
The encoder_example was used to create Ogg/Theora
files.
It was noted y4m to Theora encoding was the fastest
that I have ever seen. The Q9 Ogg/Theora took only 2
minutes 35 seconds. But the files created were way too
large compared to Xvid. The Xvid quality was very
good...
