VirtualDub frameserving to CCE issue

[dvbr]

Hi,

I captured a video with 720x480 30 fps compressed with Hufyuv, audio 48khz uncompressed, splited with multiples avi option. When serving to CCE 2.5 I got a rendering rate of only 0.370 fps. I'm just using the field swap filter, no deinterlacing, as I want a interlaced mpeg. Usual CCE settings for DVD and bitrates: 3000 min, 4500 avg, 9000 max, 3 passes. 16 hours to encode a 01:22:00 video !

Running the Task Manager I noted that VDub is consuming 60% CPU and CCE only 30%.

Do you think AviSynth could serve faster ? What can I do to speed up VDub frame server ?

Please look at my computer profile.

Thanks.

Where is your computer profile?

This is what I do. Frameserving with Avisynth is fastest, usually 30-40% faster than VD. I only use VD when absolutely necessary, like there is a filter I have to use that is not available with Avisynth. For segmented Avis, the speed of Avisynth +CCE is around 0.30 RT for my ancient PIII-500 system. Quite good, isn't it?

Hi,

Thanks for the reply, my computer profile is (just click on computer details on the header of the message):

Operating System: Windows 2000
CPU Speed: Athlon TB 1400
Harddrive space: 15GB+40GB+40GB
RAM Memory: 256MB
Video Card: Viper V330
Capture Card: Pinnacle PC TV
Motherboard: Asus A7V133
CD-ROM: none
DVD-ROM: Pioneer 113
CD Writer: LG 8080B
DVD Writer: Pioneer A04
Standalone DVD Player: Samsung 812
Other: Software DVD Player: Power DVD XP


Yes, very good speed, the same speed with a machine 3 times slower.
If you got 0.3 on your PIII 500, I will expect about 1.0 on my computer.


Regards.

Your system is very fast. But you are encoding DVD-compliant mpeg2 streams, and I only encode SVCD-compliant mpeg2 streams with max bitrate of 2500 kbps. The bitrates for your streams are much higher and need more processing time. Perhaps someone who encodes DVD mpeg2 can give you some numbers about speed. Anyway, Avisynth frameserving is the fastest way out there, because it operates in YUV2 color space.
