Divx 6.2.5 -- Almost Two Hours to Convert 20 Min MPEG 2?

[GrayStrickland]

I just installed the new Divx 6.2.5 codec. I'm using it with the Divx Pro package. I am batch converting twenty-six videos of about 20 minutes each on a Pentium 4 1.8ghz pc with 1gb ram running Win XP Pro. The files I'm converting are all MPEG 2 files created by Womble MPEG Video Wizard from VOBs. I'm using the default Divx "home theater" profile to convert the mpegs to divx, which is taking an average of ONE HOUR, FORTY-FIVE MINUTES to convert a 20 minute file. The source mpegs are about 800 mb each. The resulting divx files are about 234mb each.

Why does this take so long?

It took Womble only about 90 seconds per file to make mpegs from the VOBs (because there is no reencoding involved). I'd expect the divx encoding to take longer, but not SEVEN TIMES the length of the source material. The files I'm feeding Divx are 100% clean. No trash from downloads. The source couldn't be any cleaner or more compliant. So what is the problem?

I've had similar problems with DivX codecs over the years. Make sure your quality setting isn't set to the highest level because that will lengthen encoding times tremendously. My best advice would be to stick to the last stable DivX release that worked for you.

The major setting that determines speed with Divx is the Encoding Mode setting on the Codec tab. Going above "Balanced (Default)" gives very little improvement in picture quality (or reduced file size depending on what encoding method you're using) but will take much longer to render.

Frame size is an issue too. Encoding a 320x240 video will go much faster than a 720x480 video.

If you don't need files of a specific size use single pass constant quantizer (constant quality) mode. Pick the quality (quantizer) you want and encode in a single pass (twice as fast as 2-pass VBR encoding). You will get exactly the right bitrate to deliver that quality.

I have just encoded a 4m 47s songs with DivX Pro 6.2.2 using virtualdub, used home theatre profile, 780 kbps and balanced profile, for audio i kept the source audio and it took 4m 15s which is less then the time of the source song.
Something weird must be happening on your end.
My PC specs are listed in computer details.
The one and only thing i can assume here is that you are using Insane profile for encoding.

Sohaibrazzq:

Your specs:

Operating System: WinXP Pro SP2
CPU Speed: P4 3.00 GHz HT
Harddrive space: 320GB Segate + 160 GB WD (Both SATA)
RAM Memory: (512 Mb PC400 MHz DDR) X 2

Are better than my P4 1.8ghz pc.

I'll try it with VirtualDub Mod instead of the "Divx Converter" (part of the Divx Pro package), which does NOT let you choose anything except among profiles: home theater, high def, mobile. There is no "insane" or whatever to pick from with Divx Converter.

Divx converter is bad, Dr. DivX is better then that but it is very unstable for me.
I have done the same job in virtualdub with DivX Pro 6.2.5 and it completed in 3m 57s which is quicker then DivX Pro 6.2.2.
