VS crashes when importing a file compressed with Alparysoft

Any ideas why this happens?

Thanks for the wealth of information you have provided... NOT!!

Do you happen to know which flavour of the Alparysoft codec you have: is it the DirectShow version (in which case it at least has some chance of working with VS)? Or is it the VFW version (which is used in more specialised or advanced editing programs like Adobe Premiere)?

It would also be useful to know how exactly you applied the Alparysoft compression, at which stage of the process; what version of VS you are using; and something about your computer set-up...

I am using VS 10.
The version of Alparysoft si version 2.0 build 957.040607 alpha. In the encoding section, I select Lossless, with "enable prediction".

The computer is an AMD 3700+ with 1 200gb and 1 250gb drive. The video card is an AIW 2006 PCI Express.

As far as I can find out, that build is associated with DirectShow, but people who have tested it say that it registers itself as a directshow filter not a video codec, so it can't be tested with webcameras or most avi editors... So I am wondering if VS is counted among the latter...

Moreover, it seems it only works in the Alparysoft format. However, my understanding is that it is also supposed to be able to be set for rgb8, rgb24, rgb32, and other media types such as YUY2, YUYV etc. What does it say on the Alparysoft screen as far as MediaType Ordering is concerned? Are all the mediatypes set to 'use'?

I suppose my basic question, though, is why you felt you had to use this codec/filter, when the VS DirectShow one works perfectly well...

I am trying to use it because I am having trouble with Huffyuv.

Here's what I am trying to do:
I am trying to record in Huffyuv and into separate DVD-sized files. I can capture in Huffyuv with VS with no problem, but there's not control of the size of the file that I can see, other than stopping and restarting.
So I want to use VirtualDub because it can automatically start new files when I reach a selected size, withouth stopping the capture.
I can capture in Huffyuv with VirtualDub, and those files can be imported into VS, however the first frame looks strange. If I play the capture within VS, it plays fine; however, if I encode it, I get the same effects that are in the first frame throughout the video.

If I open the files withing VirtualDub, and click on "File Information", I can see the following differences between the Huffyuv captures in VS and the ones in VirtualDub:
If I capture in VirtualDub:
1) It captures about 60 frames per second.
2) The number of Key Frames is about half the total number of frames.
3) The field labeled "Min/avg/max/total delta frame size" in this information summary has the following value: "0/0/0 (0k)".

If I capture in VS:
1) It captures about 31 frames per second.
2) The number of Key Frames is )" equal to the total number of frames.
3) The field labeled "Min/avg/max/total delta frame size" in this information summary has the following value: "(no delta frames) .

I can't see where to adjust the capture in VirtualDub to select no Delta Frames; I think that's the main problem.

If that is the main problem, once solved, how do you intend to resolve the other problems?

Why do you need to capture to HUFFYUV? You can certainly capture a predefined file size in VS, I think, using the DirectShow capture plugin and native DV-AVI.

Don't you think you are asking this in the wrong forum? have you tried a VD one?

How do I get to this VS DirectShow Codec you are talking about? I don't see it anywhere in the pop-up window for "Video Compression".

In the capture module under "Set Up". You select the capture plugin there. No other options need to be defined except for DV type1 or type2.

The same way.

I don't need to capture Huffyuv, I prefer to do it that way. Specifically, I want to capture compressed, lossless. DV-AVI is not a choice for capturing VHS.

Is the issue of importing output from VirtualDub relevant to this forum? If it isn't, then by the same logic, the issue of exporting from VirtualDub to VS would be irrelevant in the VD forum. If it is relevant, the I am here already.

Now, after so many posts, we are finally to find out that you are capturing analog input, great.

Questions concerning the setting up of VD for capture concern VD, not VS.

The problems you are having are due to the set up you used when capturing with VD and have to be solved there, not within VS.

I'm not sure if there are users here with experience in VD, willing to lend a helping hand. I'm out of it, sorry.
