How Do I Save Time While Encoding ?

[TheHippo]

hey im using TMPG enc, i put it on the best quality when converting from divx to mpeg-1, it takes about 18hrs for 1/2 a movie, i changed the priority settings and put it on highest priority now it takes about 10hrs for 1/2 a movie, it uses 100% cpu usage (1300MHZ) but is only using 24 out of my 384 rdram, does anyone know how to make it use more ram and go faster?

[Douglesh]

As far as i know Ram wont help to decrease encoding time. The only what to do it is to either overclock your CPU (which wont even decrease it by much), or just get a better one (one that isnt intel). Also, you best to throw out your RDRAM its junk

[TheHippo]

its all i got right now and my computer is decent enough

hi,

no RDRAM does not suck. I have a P4 1.3 512 RDRAM Asus Mother board m/c. i use DVDx and CCE 2.5 sp . it gets me the Job done in real time. it 1 hr mive in 1hr. I have also tried CCE 2,5 with DVDavi one pass vbr. which gave me a very good result almost in the real time for the vedio only and then i mux the audio which i get it from vob2audio takes 10 min.

Encode your video overnight and on through the next work day, so there's no perceived loss of time. When you're busy doing other things, the psychological time "decreases."

Also, accept some video degradation as a trade-off to encoding time. Laying off some of those "best" settings will give you similar encoding results in half the time.

Hippo, your PC is fine. There are people who, if asked for advice on the problem of a car running a bit rough, would say, "drive it off a cliff, it sucks". Very helpful...some advice is worth what you pay for it - nothing.

More RAM won't help appreciably. More CPU would (most encoding tasks are almost totally CPU dependent), but it's possible that your project settings (filters, motion estimation, etc) are responsible for a lot of this encoding time. Where do you have the motion estimation set in TMPGEnc?

[TheHippo]

I set motion Estimate on Highest Quality (very slow), i dont want to change my settings, just the time it takes, but doesnt seem like i can so Thnx anyways ppl :)

Well, it sucks when it comes time to upgrade. performance is pretty good though, HOWEVER that shouldnt really help with encoding.

[revjake]

You'll save a good bit of time by taking your motion estimation down a notch to (merely) high. If you can tell the difference, you've got much better eyes (or a much larger TV) than I.

[Douglesh]

Yes, it takes %20 longer on highest quality, rather than high, and the difference it not noticeable by human eyes. Do that.

[Mordant]

Extract the audio from the DivX to WAV with Virtual Dub and use that as audio source in TMPGEnc. It reduces the encode time a great deal.

[TheHippo]

i do that, but thnx anyways

I'm sorry fellas, but rdram is mad nice. I only have 256mb and it out performs my 320mb sdram big time. Anyway, back to the original question, I found out from encoding with several different processors and dual processors that AMD athlons are the way to go. They handle multimedia way better than pentium and don't cost as much. I bought an Athlon XP 1700 (1.47 ghz) ($175 with the board), and it encodes my divx to mpeg-2 in about 3-4 hours when it is on the highest quality. If I lower the settings, i'm at around 2-2 1/2 hours. I'm scared of how the athlon 2+ ghz performs!!

Can't wait to build my dual 2100 xp Oh I can't wait till I graduate :P

in my experience, intel p4s have always kicked ass on amd when it comes to encoding. if only i could get a nice dual p4 2.4ghz system... would mean i could decode and reencode a dvd on highest quality (720x576@25fps, best vbr, highest motion search precision, floating point, a little bit of noise filtering, etc, etc) and it might get done under real time. better than the god damn 12 days it takes for my p2 350@392.

[shardison]

Beg, buy, or borrow another 600MH or better computer or three (no monitor needed) and encode the movie in 2 or three sections (a section on each computer) and join them later. Even a slow computer might take twice as long as a new fast computer, but 6 cheap, slow computers will kick 1 fast computer in the butt. Of course the room they are in will get hot and your electric bill will go up. But you will encode faster.

[Bud]

You want fast, buy a DVD-RAM Recorder, record stright to DVD-R in real time, your time only takes as long as the movie and you end up with DVD-R.

Great advice. I have a spare 800MHz P3 (384 MB PC-133) laying around, enough spare parts to build a 1GHz Duron (256 or 384MB, depending on what I have, and I need a case & power supply) and an unused 10/100 hub to suppliment my current 1.4 GHz P4 (768MB RDRAM)

Anyone got a spare case, power supply, and a couple 100 or 10/100 nic to donate?

PS I'm not worried about electric bill. All 3 PC plus 2 LCD monitors wouldn't draw more than my 9 year old laser printer. I'd just have to leave my printer off most of the time, and to give up air conditioner this summer. All I ask is for cooler than normal summer.

Depending on how you are doing it... If you are frameserving from VDub, try using some of the filters available in Vdub instead of TMPGenc. Some VDub filters are really optimized for speed.

Avoid the 2D Cleaner if possible. That filter increases encoding time like crazy.

Or try AVIsynth for some filters. Some of those are lightning fast.

your unit should encode a full movie of say 1hr 30 min in max 3hr 15min

todays first step to not to confuse you is your hard dirve configured to ultra ata 100
go to http://support.intel.com/sites/support/index.htm
and get knew busmaster drivers and ata 100 accelerator drivers
