Some quickie benchmarks WRT encoding...

[Roger Merchberger]

I set up a batch job to run some benchmarks between certain settings
on TMPGenc to see the difference between them - I set up seven batch
encodes on a small clip of Stargate SG-1 (6117 frames)

Clip 1, 2 and 3)
29.97 fps, 2200kbps CBR.
File size ended up to 59.0 MB (61,929,952 bytes) on all three clips.

Clip 1) Motion Estimate Search (High - slow)
Encoding Time: 00:08:21

Clip 2)Motion Estimate Search (Highest - very slow)
Encoding Time: 00:09:06

Clip 3)Motion Estimate Search (Motion estimate search - fast)
Encoding Time: 00:08:13

Clip 4, 5 and 6)
29.97 fps, 2300kbps (average setting) 2-pass VBR.
File size ended up to 61.5 MB (64,518,888 bytes) on all three clips.

Clip 4) Motion Estimate Search (High - slow)
Encoding Time: 00:16:30

Clip 5) Motion Estimate Search (Highest - very slow)
Encoding Time: 00:18:11

Clip 6) Motion Estimate Search (Motion estimate search - fast)
Encoding Time: 00:16:05

Clip 7)
29.97 fps, 2300kbps CBR.
File size ended up to 61.5 MB (64,518,888 bytes).
[[ this test was to see if there was a difference on the file sizes
between 2300kbps average VBR, and 2300kbps CBR. There wasn't...

Unforch, the log setting wasn't set, so I'll rerun the tests tonite &
get the logs - so I can see what the max/min/ bitrates for the VBR
encodes were.

I also haven't had a chance to look at the video, to see if there was
a difference in the motion yet...

Dunno if it will make better looking video, but it might and it looks
like as long as you set the average VBR to what you calculate with a
bitrate calculator, you can still get pretty close to filling a SVCD.

I'll let you know with better info later on...
