hd source into dvd recorder
My church has recently upgraded our video system to be hd, 1080i. We wanted to record the services and have been doing so with a converter that goes from hdmi to composite into a consumer pioneer dvd recorder as there are no dvd recorders with hdmi in.
The composite image always looked fuzzy and I thought it was a real shame that I had to downgrade a great image down to a half fuzzy mess in order to record.
A few weeks ago a pioneer lx 10 professional dvd recorder appeared for a great price and I jumped at the chance as it has component ins and outs and there aren't many with that. So now I have connected up an hdmi to component converter but the recorder doesn't display anything. When I dial my input all the way down to PAL it displays.
Tell me, am I trying to do the impossible here? (get a 1080i source to go into the lx 10)
It looks as if I will have to convert to pal.
Would a component pal image look better than the composite?
A common misconception is that DVD's contain HD video. They do not.
Here is a list of supported DVD video resolutions.
To actually record and distribute HD video, Blu-ray is the consumer standard.
Here is a list of Blu-ray supported video formats.
I don't know what the pro standard for recording and distributing HD, but I assume it eventually must get transferred to Blu-ray or a computer video file.
So, to record to DVD, you will need to scale your video to one of the supported (non-HD) formats, which may be further restricted by the DVD recorder itself.
I'm not sure what exactly is available for direct to Blu-ray recorders. Tascam has one, but I think the only way to record HD is to use a firewire or, maybe, USB connection.
DVD recorders are SD, not HD, and as such, cannot decode the composite HD signal you're sending it. Your video needs to be downsampled to SD before running it to the DVD recorder. If you try to do it on the fly, you're almost always going to be disappointed in the final video quality of the DVD.
Hollywood can produce a high-quality DVD, but not on the fly. They use multi-pass compression algorithms to give them the best balance between compression and file size and usually perform a completely different set of color correction tailored for the limited color gamut of SD.

Thanks for the responses
I ended up getting an HDMI - HDMI convertor to go to SD and then piping that into my HDMI - composite converter which goes into the DVD recorder. PHEW!
With a lot of audio sync correction, it all works and the quality is better than the composite, but obviously not as good as a Hollywood DVD!
Thanks for your insights
