BTW I'm on Windows 7 x Select FFDshow , under encoder select mpeg-4 or xvid, change the mode to one pass quantizer and drag the slider to 4.
That's a reasonable starting place. Last edited by davexnet; 24th Feb at Reason: not windows 7. Or install koepis xvid codec. Well I installed that Xvid codec and it does show up in VirtualDub.
Trying it now, it seems to work but is very slow. In any case, I would really like to be able to use ffdshow as I had access to other codecs and was familiar with it. I don't need instructions on how to use it within VirtualDub, it doesn't show up in VirtualDub! I can't select it, it's not there! It's installed on the system, but for reason VirtualDub doesn't see it.
Does the download from Koepi work in Win 74 bit? I didn't realize that. This means that 32 bit video editors require 32 bit codecs, 64 bit video editors require 64 bit codecs. The two don't mix. It sounds like you are trying access 32 bit ffdshow from 64 bit VirtualDub , or vice versa. On top of that there is a problem where some installers put the files in the wrong place 32 bit dlls end up in the folder for 64 bit dlls, or vice versa -- as is the case with LAME. So you have to manually fix the installation.

Train: Thanks for trying! I looked at several of the tutorials and my opinion has remained unchanged. Trying to use VirtualDub is like starting over with PCs at ground zero. Everything is so convoluted. Based on many of the tutorials I watched, there are no recommended codecs included as part of the package. So you have to download and install all this other stuff, adjust many settings to something other than the defaults, and on and on.
IMO, VirtualDub is definitely not for anyone wanting to work on a handful of videos per year IOW, the average user shooting home video. This is a serious, many hours long commitment in learning and experimentation.
Which leads to a question Is there anything out there that's free and easy to use for the average Joe or HAN? While VirtualDub may be a good free app, it's far from easy to use! I can't remember it ever running on any PC I've tried it on without it crashing. It slightly decreases encoding speed and leads to a slight quality loss along but the decrease in used bitrate is considerable in comparison.
The Debug tab is less interesting but it allows you to configure the FourCC code. If you're using an alternative decoder than XviD or ffdshow, you could change the FourCC used in order for another decoder to recognize and play the video but this option is often of little to no use. And before you get started with the first pass there's one more feature to look at, the zones:.
You can define multiple zones where you apply special settings. For instance in the example above, I have two zones, one starting at the first frame, using the regular settings, and another one starting at the point where the credits start. Press Add to add another zone, then press Edit to configure the zone:. The first thing to do is set the start frame at the appropriate position. Then we have the Rate control, where you can choose between applying a different Weight to the bitrate, or specify a Quantizer compression factor.
As you can see, I have chosen a weight of 0. However, you might want to use a fixed quantizer in the range of 20 for now as the weight option seems to be bugged. Greyscale enables a mode optimized for greyscale black and white content. This can help to reduce the "red stairs" effect. BVOP sensitivity is a treshold for B-frames. The higher the value, the more b-frames will be used and using negative values the number of b-frames will be reduced.
That being done you're now officially ready for the first pass. If you want to set the path of the stats file that is written during the first pass, press the Here you can click on the more But if you do, make sure you write that value down because you'll have to set it for the 2nd pass as well.
Also make sure the Discard first pass option is selected. Otherwise, the codec will create a pretty useless AVI file during the first pass and writing that AVI also slows the process down. Full quality first pass is not useful unless you want to create a best quality possible video in addition to the second pass output. This enables the Target size button.
If you click on the Target size button, it will change to a Target bitrate button, and you can now either enter a desired bitrate manually, or use the slider to set a target bitrate. If you had previously changed the Stats filename for the first pass, make sure you enter the same value here now. I-frame boost can be used to give an I-frame more bits than calculated in the bitrate curve.
Then we have the I-frame bitrate reduction options. The first one set the threshold for when the reduction is applied, and the 2nd value sets the reduction factor. Max overflow improvement and Max overflow degradation indicate how much the codec can compensate during undersized and oversized sections of the video. If you're getting high fluctuations in quantizers noticeable by fluctuations in image quality , try reducing those values to This might hurt size predictability though.
Curve compression controls how the bitrate curve is being scaled. High bitrate scene degradation indicates how many bits are "shaved off" high motion scenes, and Low bitrate scenes improvement is the same for low motion scenes.
