View Full Version : Are my encoding times right?

CCE 2.5
AVS file...
LoadPlugin("C:\WINNT\SYSTEM32\mpeg2dec.dll")
mpeg2source("K:\BHD2\BHD.d2v")
ResampleAudio(44100)

P4 1.6A overclocked to 2.56 GHz
EPOX 4G4A+ motherboard
512 meg running at DDR400 speed
2 x 120 gig Western Digital 7200 RPM hard drives (RAID 0)
Win 2000 All NTFS partitions

With the above system, I encode at about 2.0 to 2.1 x real time.
Is this about what I should be getting or is something setup wrong. I've read that Avisynth is supposed to be much faster than VFAPI. This is my first time to really use Avisynth because I could never get it working on a system that I had used VFAPI on, so I'm not to sure that I really want to setup VFAPI on this system just to do some testing.

My other system...
Duron 950 @ 1.05Ghz
EPOX 8KHA+
512 DDR
2 x 30 gig maxtors (RAID 0)
Win 2000 NTFS partitions

This system would encode at .9x real time using VFAPI. Like I said abouve, I couldn't get Avisynth working on this system.

Yet another system...
Tbird @ 1.5GHz
EPOX 8KHA+
512 DDR
2 x 40 gig WD (RAID 0)
Win 2000 NTFS partitions
Using VFAPI, it encodes at around 1.5x real time.

What are you doing with the video stream? If you're running a bunch of VDub filters and encoding to an MPEG4 variant, Avisynth isn't likely to be your limiting factor; if you're doing a direct stream copy out to RGB32, your hard drive will probably limit you; etc.

By the same token, a more direct comparison would be to fast recompress to MJPEG on all of the above platforms.

Hi-

Yes, your speeds are about right. I assume you're just using a basic Force Film in DVD2AVI with no other filters added. If you'd like to compare your CCE speeds with those from other machines and maybe brag some more, then have a look at this huge thread down in the DVD2SVCD Forum:

CCE Speeds (http://forum.doom9.org/showthread.php?s=&threadid=5777)

Don't you do any cropping and resizing? If you resize, then the SimpleResize is a bit faster than the others.

I'm not using any filters or anything. I'm just decreasing the size of the mpv file so that it will fit on a DVR-R.

1. rip movie from DVD
2. DVD2AVI to get the d2v file and demux the ac3 audio stream I want to keep.
3. Avisynth and CCE to get an mpv file the will fit on a DVD-R
4. Maestro to put it all back together with the chapters.
5. Burn it to DVD.

I end up with a DVD-R with no special features or menues, but I don't have any problem living without those features. The only menu I have made was for the Star Trek TNG season 2 set.

Ok so you're recompressing back to MPEG2. That's probably taking a solid chunk, if not the majority of your CPU cycles.

(Can't you burn the original VOBs straight to DVD?)

If the movie is less than 4.7 GB, then you can just burn it, but most of the movies being put out today are dual layer disk. This means that they will be around 6 to 7 GB. I've seen 3 DVDs that had a total size of less than 4.7 GB with all the menus.

True, but with SmartRipper you should be able to extract only the video streams you want. In any case, I wonder how long it'll be until consumer burners can generate dual-layer disks..
