Editing Question about Virtualdub

[gatewayedit]

I am not sure how many people here used SolveigMM VideoSplitter for WMV file. In SolveigMM, I was able to choose several segments in a movie clip to export into a single file. Does Virtualdub have functions like this for avi files? For example, let's say I have a 1 hour avi file, and I want to export 4:00-14:00 and 34:00-39:00 into one single file. Do I have to save each clip into individual clip and THEN combine into one? Or is there a way at Virtualdub I can put multiple begin/end marks? Thank you for answering my noob question

Select the parts you don't want and press the delete button(on your keyboard). Save as a single file. Be sure to use video->direct stream copy to avoid reconversion.

To multiple cuts to an AVI file in VDub we use a program called AviSynth that runs in the background. With it installed, VDub can open scripts you write and save as an .avs file. Once you write the AVS file, you open VirtualDub (VDub) and open the AVS script like it is a video file. The two commands you use in your situation are the AVISource and the Trim function:

AVISource("C:\videos\test.avi")
Trim(7193,25173)+Trim(61140,70131)

This script opens the file named "test.avi" chooses the two clips from frames 7193 to 25173 and 61140 to 70131. You get the exact frame numbers by loading the video into VDub, select G0->Go to Frame. Enter the time you want VDub to look at and in the bottom of the display it will show you the frame number.

Once you open the video this way, you can save the video under its own name or frameserve it to another application.

Hope this helps.

Using Avisynth as M Bruner suggests will work, but the output will necessarily be re-encoded.
By contrast, with Baldrick's solution using Direct Stream Copy there is no re-encoding.

By contrast, with Baldrick's solution using Direct Stream Copy there is no re-encoding.

But then you can only cut on key frames. Which with Divx/Xvid files can be 300 frames apart. Use VirtualDub's Smart Rendering feature along with Full Processing Mode and only cut GOPs will be re-rendered.

jagabo is right.

You could also use Cut Assistant, which is just a front end and uses VirutalDub for the actual cutting. But some people find it easier to define the cuts here.

Be sure to set a codec in Cut Assistant's settings to enable the Smart Rendering of Virtual Dub, as described by jagabo.
