How much faster is P4 vs Athlon using TMPGenc?

[vetski179]

I'm using TMPGenc to convert to various formats. Sometimes it takes 8-10 HOURS. I have a 1G Athlon system w/512mem. I read TMPGenc is optimized for Pentium 4. I may be interested in putting together a new system w/P4 if there's a big difference in encoding times. What has been your experiences with the time it takes to encode?

I am using a P4 1.6Ghz 256DDR Ram. Usually when I convert amovie it seems to convert in real time, which means if the movie is 2 hours it usually takes 10-20 minutes longer than the movie length. I just encoded two vcds (ntscfilm) Each with the motion search precision on high quality and the movies were 2 hours long each and they only took 2hrs 20 min each to encode.

I have done a 2 hour movie in 1 hour 45 minutes on the following:

P4 2.4GHz
512 Ram

Not sure what the other specs are as it was a work PC but I was figured
out that if I encode on my home system (500MHz K6-2) it takes approx.
8-13 hours,so, I can do a weeks worth of encoding on the P4 in one night!

The longest encode I ever had was an experiment with one of Kwag's
templates. I did the "One CD VCD" template and started the job up. I was
going away for the weekend (Fri - Sun night) and when I got back it still
was not finished. I think it eventually took about 31 hours. NEVER again,
I'll just split my movies up for now.

Since we are the subject of Hardware - What could a Xeon CPU be
compared to? Like,

Xeon P4 1.4 GHz = ? (3 regular P4's?)

Just curious.

I have a Athlon XP1500 with 512 MB DDR ram and I have been capturing Home videos and encoding them with TMPGEnc. They are around 30 minutes long and it takes around 45 minutes to finish.

i have a p4 1.8 and 512 ram i encode in half time probably maybe a little more . a 2 hour movie in a little over an hour. music vids in a little less than real time. i always seem to think i encode in about half time but i think its a tad longer

I wanna know how long it takes with one of those new P4 running at 3.06 Ghz....man I want one so bad

I use a Intel Celeron at 1.7 Ghz, and almost get real time. Usualy about 20 minutes long than the movie is. And for shows, its around 5 minutes longer. Alot better than my little P3 running at 1.0 Ghz, took forever with that baby

Thanks for all your responses. I have been doing DVD's to DVD's, where I cut out the unnecessary stuff and just go with the movie. I have been using the following settings to encode to DVD using TMPGenc Wizard: DVD 4:3, CBR MPEG 1 Layer II audio(MP2), Setting the source as either 4:3 or 16:9, resizing the picture to No Margin (keep aspect ratio), DC component precision to 10 bits, and using Normal motion search precision. Excellent results have been obtained with these settings (hope I don't end up getting a wide screen TV anytime soon!). Last night, I encoded Basic Instinct. Took 13 hours. Sounds like you guys are getting much faster encoding times with your hi speed P4's.

vetski179, non't be too amazed by some of these encoding times. I would guess most of the posters in this thread were talking about encoding to standard VCD. This is always going to be MUCH MUCH quicker than encoding to DVD specs.

I do a lot of Divx to DVD encoding on a P4 2.2 with 512Mb DDR. Using Tmpgenc, 2-pass VBR, High quality motion search, 16:9 display, avg bitrate around 4500 to 5000 a 2 hour movie will typically take 8 or 9 hours to encode.

Just for interest and comparison with some of the other posters, I just started an encode of a 2hr 5min movie to a standard VCD template. 5 Minutes into the movie and it is encoding slightly faster than real time. Tmpgenc is showing an estimated encoding time of 1hr 58.

This is 4 or 5 times faster than my encodes to DVD standard. When comparing encode times, make sure you compare like with like.

Hope this helps

TMPG now supports hyperthreading which is only available in the new 3GHz P4 and beyond, which will make a big difference in encoding times and make a bigger hole in your pocket . Otherwise you will find P4s and AMDs comparable at the equivalent speeds.

I also agree with Bugster, TMPG for DVD spec encoding is much slower than for VCD.

Yes, encoding times vary according to the frame size you are encoding to. 352x288 is quicker than either 352x576 (CVD) or 720x576. For CVD encodes on my XP1600 it takes about 1'20" for 30 mins of video in CQ mode.
