Basic Q: Marvel G400 & 450, captured files interlaced?

[Jkun]

Basic question on the Marvel cards: if you capture interlaced material (via HuffYUV)in PAL or NTSC, is the resulting AVI also interlaced or has the Marvel hardware deinterlaced it?

When I search about this in the posts, I found that the Marvel 400 is having a problem with this causing fuzzy pictures in PAL? And the 450 has it in both PAL & NTSC?

If the Marvels cannot capture interlaced material, what alternatives are there, that can handle HuffYUV (except TV cards, they're way too noisy)?

G400 captures fine PAL interlaced videos in both MJPEG and YUY2. Cannot say anything about RGB: it always freezes on my PC.

But what about those comments then about PAL grabs being blurry & complaints about de-interlacing not possible to disable?

Are you sure your grabs are interlaced?

Matrox G400 captures in PAL are exhalent , as i see it there's two problems you may be referring to

1 the G400 TV (most likely all others) de-interlaces MJPEG on playback to the PC monitior(which is a Progressive device) this make play back a little blurred , but the output to the TV/video is interlaced because they are interlaces
device's

2 if you're talking about blurred still grabs you must disable high quality stills in the config of matrox-prowerVCR
because this blended's about 5 frames together into one still jpeg picture.

zeb,
Feel free to ask any specific questions on PAL captrues

PS, dose anyone know how to disable de-interlacing on PC / because their are some setting for it in the registry??

zeb7, I don't care about the quality on PC monitor, but it may be that this is why I am confused to how the G400 works, what quality issues there are etc. That's why I asked.

I simply need to know if the AVIs captured (HuffYUV) (in PAL and NTSC) are interlaced and not progressive video.

thx!

YES, they are all interlaced. If the source is film, aviutil has a very nice IVTC function to restore 24 progressive frames. You can also try smart-deinterlace for vdub, which may improve the look for progressive playback on the computer monitor.

As an example, just capture a huffy clip at any resolution and open it in vdub. If you scroll through the clip you will clearly see the interlacing effect.

Thanks all for your help!

The complaints about not being able to disable deinterlacing were for TV watching on the PC monitor and for still grabbing, not for video stream capture.
