RV9 encoding speed ?

Hi everybody, Does that happen to you too or only to me? i really like the RV9 , but the problem is that i wait too long to encode a whole movie. for 2h movie i need 10 hours for 2 pass encoding. with DivX i need the half of that time - 5h. so i was wondering if my settings are wrong or the RV9 codec is a "lil" slow. i use the latest Milestone of the RV9. i appreciate any information, tipps & suggestion. thanks The Shemeta

A 2-hour show only takes me like 6 hours with Helix Producer Pro (the GUI). Something is wrong with how you're encoding. Are you converting to RGB or using extra filters on your RV9 encodes? Are you using the Helix CLI by it self or are you using a GUI like (RMFactory)?

well it doesn't matter what i use. it is still 10h. but there is something else. maybe your computer is faster than mine. i have PIII M 1Ghz notebook with 256 MB & 20GB HDD.

My computer isn't that much faster. It is a 1.4 ghz athlon xp 256 meg ram.

i think it's quite linear : a 2ghz cpu will do the job about twice faster than a 1ghz one.i also consider that rv9 encoding is twice longer than divx encoding with the same avisynth script . see you...

OK, now i get it. so it's normal if the RV9 encoding is longer than the DivX. that's not very happy news, but oh well! what can i do? just wait longer! :(

It should be noted also that most laptop harddrives are much slower than desktop harddrives. 4200rpm for laptop harddrives as opposed to 5400/7200rpm for normal IDE Desktop harddrives..

Maybe it's a Super Laptop from the army with a low-heat quantum processor :D

encoding length ~~ play lenth @ 2.4ghz

I am afraid RV9 is as fast as it can be without sacrificing quality. Everything is highly assembly and MMX/SSE/SSE2 optimized, and multi-threaded, it just has to do many more calculations. and in the upcoming EHQ mode, it has to do even more... thus really making good use of those latest P4 and AMD processors. In RV9 default mode, I have about real-time encoding on a 2.4GHz P4. A PIII does not have SSE2, which we use quite a bit, so in addition to the difference in clock speed, there will be about 20% performance hit for not having SSE2. Based on this, let's do a quick calculation: 24 fps on a P4 2.4 GHz: 24 / (2.4/1.0) = 10 fps Then, subtract 20% for lack of SSE2: 8 fps So, at 8 fps, a 2 hour two pass encode will take around 2 hr * (24/8) * 2 passes = 12 hours, or 10 hours for a shorter movie Sorry, but at least my calculations match your experience pretty well
