I'm in Australia so I'm using PAL. I read that the recording dimensions forPhil. Is your capture card hardware based encoding or software?
PAL should be 720 wide x 576 high, but when I do this I notice that it uses
a lot more CPU (20% more) and the picture quality improvement is only
marginal. Is 720 x 576 right? What do most people set this to on PAL
systems. Also, I thought I should also set the X "modes" and "metamodes"
settings to 720x576 but it doesn't allow this. Am I trying to do something
stupid here?
In my case I have a PVR350 (h/w based) + DVB card. Both are set to record at 720x576 in Myth Setup.
The capture resolution should reflect your source resolution ..... ie there is no point capturing at 720x576 if you have a 4:3 analogue stream. 640x480 (4:3) is more than enough.
If you are capturing an analogue output (but digital broadcast) stream such as Sky, (Foxtel?) then you want a higher resolution. Generally these broadcasts are widescreen, so you want as much vertical resolution as you can get, since most of them are letterboxed anyway. 720x576 only gives 5:4 aspect, whereas most shows are 16:9 or movies even worse
My settings are
1 / The DVB card ignores this setting (it doesn't have a choice about the resolution, as Myth just saves the mpg2 stream
2004-12-12 20:01:53 DVB#0 Recorder: Card opened successfully.
Videostream: ASPECT: 16:9 Size = 704x576 FRate: 25 fps BRate: 15.00 Mbit/s
Audiostream: Layer: 1 BRate: 128 kb/s Freq: 0.0 kHz
2 / More interestingly (for me at least) is that I tried to get an display compatible modeline out of my TNT2 card, to drive a 1280x720 projector. In the end I gave up and feed it 800x600, which gives me the correct aspect ratio. I assume that Myth on playback is scaling the 720x576 to 800x600, and then the projector is scaling it to 1280x720 to display. It looks fine, but not for a purist to consider
Hope something helps! Steve
