Why does VirtualDub say i have no capture card when i do
i have a aver tv card,
when i try to load VirtualDub it says it cannot find a capture card.
is this because im running the aver tv software as well??

any help would be great

Which OS are you running?

VirtualDub doesn't see AverTV's WMD drivers.
You have to use a 3rd party hackd driver or use windows legacy video capture VFW drivers

[kel]

im using windows 98se.

[Trik]

In win98se to get the legacy video cap drivers you have to install webtv for windows off the win98 cd.

There may be another way to get them but I haven't found it...

[kel]

how do i insatll these drivers?

[Trik]

get the win98cd
goto add/remove programs and choose the tab for adding removing windows components.
All the way at the bottom is webtv.

I'm having the same issue. I just got a Hauppauge WinTV-PVR 250 (replacing the Dazzle package which I got from Dell). The Hauppague software is nice for TV viewing and as a PVR, but it seems to be limmited to capturing only to MPEG format (I prefer uncompressed AVI so that I can TMPEG it).

Would I be able to install a Win98 VFW driver on an XP machine? I'll give it a shot and report back. If I'm stuck to using the Hauppauge software in MPEG format, I'm going to return the board.

That kind sound like very dumb idea portow, Why would you want use TMPEG when you ready have HW MPEG2 encode that save you hour of work in re-encode.

[Trik]

I've never used XP, but I would think that WinXP has the legacy video and audio capture drivers installed on it, win2k does.

Go into device manager and check sound video and game controllers.
You may need to change the view to show hidden devices.

I have never gotten a HW Mpeg2 card because I do some processing (IVTC, noise reduction, logo removal) before I burn to SVCD. So I wouldn't think his idea is so dumb if quality is more important than time.

[SHS]

"logo removal" how can remove something like this when it enbed in to the signel.

[lemmy999]

Well, it is more like "logo blur" but it is a filter called logoaway. It just interpolates what should be where the logo is. It works great it times and is no more annoying than the logo at others. I am usually capturing off of WGN and they have a perfect logo for logoaway. It is a rectangle and it is solid. With the transparent ones you still can see the video behind the logo and you feel bad screwing with that.

[SHS]

Where this VirtualDub Filter at I like try on DirecTV box

Welp, SHS I don't think striving for quality is a "very dumb idea." BTW, that's not the nicest or most neutral way of stating that you can't comprehend why someone would do something. A better way of phrasing it would be "Why would you want to encode AVI into MPEG-2 when you can just capture strait to MPEG-2 via HW"

Anyway....

I called Hauppauge. Turns out that the Hauppauge WinTV-PVR 250 cannot capture in any other format other than MPEG. If I want to capture to AVI, they recommend the WinTV-PVR-pci (Model 880) for $199 or the WinTV-radio (Model 401). The 880 will give me HW MPEG-2

I have the Aver TV card as well.. I was able to get it to work in VirtualDub because I have a Logitech Quickcam and it recognizes the cam on load.. Then I select source and it gives the option of the "Conexant capture". So... get a webcam

BTW, with this card there are some excellent AverTV compatible capture drivers on sourceforge where you can get the card up to 720x480 capture resolution instead of just 720x240. Let me know if you want the URL and I'll find it for you when I get home from work.

portow yes I know that.
Only first WinTV-PVR output YUV stream becuase it has BT878a chipset plus Vision Tech Kfir1 MPEG2 encoder where WinTV-PVR 250/350 can only output MPEG stream in RealTime.
You miss the point of it why do the long hard way when can do this in RealTime save you lot hours in encoding.

WinTV-Radio (Model 401)
AVI MAX cap 325x240(NTSC) some PAL user can go higher sceen size
Soft base MPEG2 encoding can be use but need less to say your stuck with CBR and you need very fast CPU.

WinTV-PVR (Model 880)
AVI MAX cap 325x240(NTSC) some PAL user can go higher sceen size
HM MPEG2 encoder up to 704x480(NTSC) or 576(PAL) 12Mbit/sec and all must no CPU load when encode MPEG2 max out but the Perview Windows dose eat up some CPU usage.

WinTV-PVR 250 (Model 890)
No AVI support it dosen't output YUV stream format so can't use other applications being thoses applications where base on BT8xx chipset.
HW encoding only output MPEG2 in RealTime you get DVD quality depend on bitrate and video format you use, For example, MPEG1 will give lower quality than MPEG2. MPEG2 8Mbits/sec will give better quality than MPEG2 2Mbits/sec.
Soft MPEG2 decode in Perview Widows or Full screen this take up a bit CPU usage because it using a Soft Decoder.

calamari only if your a PAL user and not all PAL user can do this depend on where you live and NTSC user can't do this at all with out some kind HW acceleration.

NTSC Broadcasts are sent in 2 fields (Top & Bottom) this essentialy makes it 60Fps matching 60Hz and this causes much strain on todays capture cards that have no HW acceleration even with the fastest CPU and harddisk you can buy rigth now, unless your willing to fork out some big bucks to be able to capture in full 60fps you need a custom avi capture card which cost a lot more $1000, So you will only be able capture half the resolution for the first field an half the resolution of the second field.

I'm currently running a WinTV-Radio/DBX (Model 401)

I just finished a small cap @ 640x480 in DivX5 using VirtualDub, my processor usage never reached 30% and I had zero dropped frames.

System is a Kt333 Dragon Ultra, Athlon 1600Xp, 512 megs of PC2700 ram, using onboard sound and 2x 20 gig Western Digital 7200rpm UDMA drives, Liteon 16/48 DVD, Liteon 10/16/40 CDRW, Win98se.

This is also a clean install of 98se.
I had to reformat because I had 4 different TV cards (testing them to see which was best for what) on the old install and couldn't keep it stable any more.

Of course I need to make sure I can duplicate those capture results but it looks promising.

With DivX5 you can set custom capture sizes from within the codec's settings so theres no telling how high I'll be able to go with this before it starts dropping frames if 640x480 was at <30% CPU usage...

[SHS]

Oh really then what do call this then

Like you I have very fast system to.

[Trik]

Under Video use Preview and under capture use *Hide on Capture*

You won't see whats being captured but your processor usage becomes a LOT lower.

[dj360]

Trik:

What do you do when you do go to preview and hide on capture and the CPU usage is still high? Is it a ram problem then?

[SHS]

No it not the memory

[Trik]

dj360:

What motherboard do you have and what 800 mhz processor?

Also you have an onboard vid chip and it will be using more system resources than an AGP or even PCI vid card, esp memory.

[dj360]

I don't know the kind of motherboard I have but I have a HP Brio. Does that help?

[Trik]

I'm not familiar with HP's product lines.

What would help is to know if you have a P3 or a Celeron.
I don't know if HP ever used Athlons or Durons.

But depending on the processor type your cache size will be different, and that can make a big difference.

[dj360]

I have Intel Celeron Processor 801 MHz, 120 MB of RAM, 8 MB Video Card. Does this look like I am stuck capping at 320x240?

[Trik]

Lets just say, if you plan on doing lots of capturing you probably should look into building a new system.
Or getting one of the beefier dells.

Personally I'd build.
Building usually gives you more upgrade paths and flexability.

A lot of times with prebuilt systems you have to use specific parts (their memory sticks or addon cards) which are 2 or 3x more expensive as standard items.

If you do build, start with a nice powerfull power supply.
Todays equipment draws a lot of power.
So figure a 350 watt as a minimum.
You want one that has a minimum of 180 watts on the 3.3 and 5 volt rails combined. With 220 being even better.

Compairing the quailty of what you get from AVI to MPEG2 via TMPGEnc to what I get from a strait MPEG-2 capture on the 250, I'd say that TMPGEnc does a much better job. I especially like TMPGEnc's ability to preview what your changes will make to the competed MPEG-2 stream. This is not to say that the 250 does a poor job - quite the contrary. It's just not as sharp as the TMPGEnc. Then again, TMPGEnc takes hours after you've captured your source, while the 250 encodes in real-time. As a PVR I'd strongly recommend the 250. For Quality archiving, I'd recommend TMPGEnc.

I may RMA my 250 and go for the 880 rather than the 401.

SMS, based on what you've written, seems as if the 880 does all the 250 does and much more - am I right in this assumption?

I'd like to be able to use programs such as VirturalDub and others for my capture and to be able to write to DVIX rather than be stuck with a manufacture's software and a set output format. For an extra $50, it seems like the 880 is aa much better deal. I only wish the Hauppauge website did as good a job in describing their products as you do. There is nothing on their website that describes what you just said - at least no where I could find it.

[SHS]

Yes your assumption is 100% rigth the first PVR (880) dose more then the 250/350 base on what I know about it.
As for DivX there is a way to convert the MPEG to DivX and all you need is Vidomi Encoder and there even away of converting the MPEG to AVI MPEG Mediator.
In tell MPEG4/DivX HW encoder come out we stuck with MPEG2 this due to license MPEG patent holders MPEGLA which has license per movie/per minute (because DivX is Mpeg-4). The MPEGLA fee for itself is such a high license price tag that no one wants it at this time, I'am even supize that DivX Networks could even do this at all.
