[MEncoder-users] 2 pass encoding from tuners?

[Roger Andreassen]

Hi all,

I have a good line to encode DVD's slower than real-time, and I have a real 
fast script to run the tuner cards with cron jobs.

Now to combine these two I'd like to try to have high quality from the TV 
tuners.

Dig this: If I settle for mp3lame sound encoding and could find a 
intermediate 'storage' level for the pictures I could encode the video 
later.

When I grab TV with mencoder it's usually bc I'm busy with something else. 
When the CPU load gets too high I'm afraid the encoding turns into crap. I 
reckon the harddisk bandwith should be ample enough to _store_ the raw video 
(could get to 20M/sec). I could do a final compress later with a nice level, 
then I could doctor my script to use much lesser cpu.

I have a AMD 1.4GHz, 512 Mb and WD800 and WD1200 harddisks. If both tuners 
kicks in at once they're usually at 35% + 35% (Pinnacle PCTV Pros), that's 
leaves me with just the 30% of oomph which I try to adress.

In the ye olde days I heard you should get a dedicated AV drive for video 
use. Does the disks today survive a couple hours sustained load provided I 
cool the cabinet?
