CPU endcoding times??

About how long will it take for a Pent. 4 2.5 Ghtz Computer????

We need much more information to take a "guess". Information such as:

1. Resolution, time length and file type of original file
2. Which encoder will you be using
3. Which rate control mode ie: CBR, VBR, CQ, etc
4. What format will you be encoding to ie: VCD, SVCD, DVD etc
5. What resolution you will be encoding to

I will be using Tmpeg to encode. Also it will be taking a DVD to a VCD, encoding using the default VCD template. I currently have a 1.3 ghtz pent.4. It takes at least 6 hours on the very slow high quality setting in Tmpeg. I am very interested in the new HP Multi Media computer at circuit city. Any suggestions on buying this computer?? It is a 2.5ghtz Pent.4, 1gig of DDR Ram, DVD Burner, and a T.V. tuner card. Hope I gave enought info to make a guess.

Just as a data point. I had a Tbird 1.2Ghz and encode MPEG2 with CCE. I normally got 1.1x source runtime per pass. I now have a AMD 2200XP+ and it takes 0.7x source runtime per pass.

On the 1.2Ghz MPEG2 encodes in TMPGenc (with the same AVS script file) took ~3x source runtime per pass. I don't remember the numbers of MPEG1 encodes.

Resizing and filters slow encoding down. IIRC TMPGenc wants RGB video so YUY/YUV data also slows things down. And of course motion search makes a huge difference.

I have an AMD Duron 900mhz, and encoding with cce 2.5 to svcd wtih bicubic resize, I ususally get speeds around 0.6 is this a normal speed or should it be faster. If so, how do I get it faster?

ssj2gohan29:

With TMPGenc processor speed seems to provide the largest performance boost. I would "guess" that if you were to continue to record to VCD, that using the sam procedures it might take 3.5-4 hours, recording to DVD and not resizing might be 20-40 minutes less than that.

If you ever transcode using ReMpeg, here are my times. When I transcode a movie to a lower bitrate, I always use the highest-quality settings possible. I have a dual pIII-933mhz processor machine, and it takes about 21 or 22 hours on average when I let ReMpeg use both processors on high priority.

It's a pain, but worth the quality. See:

I bet you can't tell which one is compressed :) (Pay no attention to the brightness difference, a lot of people say the colors are different, but it's just the brightness change as a result of the transcoding)
