Handbrake encode times (mac vs pc?)

Hey guys
I use handbrake to convert 1080p mkv files to appletv 720p format. It usually takes about 8-10 hours for a 2 hour movie. I was curious if people with windows based versions on a pc have faster conversion times?

thanks
Mo
 
CPU usage (dual core) reaches around 200% when I do encodes, so I'd assume it wouldn't be any quicker on Windows, unless it uses a different version of the encoders..
 
The encoders are the same. There should be negligible speed difference between the platforms.
 
using my hackintosh/windows machine clocked at 3.0GHz the times are pretty much the same.

(using the latest SVN, quoted from memory).

• Mac, 27mins
• PC, 25mins


i guess the small difference would be from what other programs were using up the CPU and RAM etc.

the things i DO notice a difference in are ENCODE QUALITY!! mac version is alot better :)
 
ok i did an encode finally. on a TS folder of Scrubs. i WOULD attach photos but you loose quality... if you want the full quality screen shot as evidence just PM me with an email address.

here are my settings/specs with the pc vs mac encoding.

handbrake version 0.9.3 on both machines

title 3
saved to desktop
mp4 file
68% constant quality
AC3 passthru
chapter markers created
anamorphic: strict, output 750x574

mac:
• started at 6.04pm,
• finished at 6.27pm
• encode time: 23mins
• 22.06fps Average
• file size: 688.5MB (721, 898, 282 bytes)

PC:
• started at 3.41pm
• finished at 4.08pm
• encode time: 27mins
• 18.53fps Average
• file size: 715MB (750, 088, 192 bytes)

i ran it on my hackintosh 3.0GHz with 2GB RAM, under windows handbrake an average of 4fps slower then handbrake for Mac. the PC encode is very flakey, and there are artifacts EVERYWHERE, mind you i was streaming it to my laptop..but the mac version was streamed aswell both from windows so i dont understand why its so blotchy.

i have NO idea why the PC version made a bigger file.. wierd. it was worser quality as well.

this clearly shows the difference in handbrake encodes in both time and quality, i.e. Macs are better :)

Would have to have an encode log from each platform to bear this out as truth. Just doesn't make sense tbh. I have to believe that something was different in the two encodes besides which machine it was run on.

hhmm ok how do i get the log files then?? will they still be on there even though ive restarted the computer/quit handbrake etcetc?
 
ok so here is the windows log.. couldnt find the mac log :confused::confused:
