480p capture card.

[PeteInSF]

I was comparing the quality of s-video to 480p today and noticed there is quite a difference viewing the same DirecTV source...

My question is this, since the resolution is the same for both, would not using a 480p capture card improve sage's PQ without using any additional storage space.

Second, is 480p capture technically more difficult then grabbing s-video (or composite)?

In all of this I am assuming there is no such beast as a 480p encoder device, is there?

There is nothing (in consumer space) that can capture greater than 480i. 480p may have the same resolution but it's twice the frame rate, 480i is 30fps (60 feilds/sec) while 480p is 60fps.

How did you get 480p? I thought DTV was either 480i or HD?

Stanger,

I have a HD reciever that has 15pin VGA output that I have set to 480p.

It looks a lot better than the s-video, the source could be 480i but even with that it looks much better.

Would would my storage question be valid with 480i instead of 480p?

It's the 15 pin VGA that's making the video look better. It's essentially giving you a true RGB output direct from the boxes decoder which is going to look better than Y/C (S-Video) everytime.

Unfortunately there's nothing currently available to record that signal for use with Sage.

How about a card like this one...

It had YUV Component inputs and hardware encoder

And you can get one for the low, low price of only $1700, and it doesn't capture better than 480i either.

Likely, the big difference between 480i/p is the deinterlacing. SageTV (or more correctly the decoders) will deinterlace the video for you, you can hook your SageTV box up to the VGA in on your display and you can have everything upconverted to 1080i or whatever your display's native resolution is.
