what works for you? 1080i + adaptive deinterlacing AGP

mybrains · 2006-07-04, 05:33

Im trying to find out what ppl have sucessfully got working with VMR9 and Adaptive de interclacing at 1080 without using excessive CPU/software overhead. This means video card GPU processing, DxVA etc).

The delema is how to upgrade my FX5200 AGp video card to achieve this with MP (amd64 3000). I would also think purevideo_HD & h264 support is very forward thinking.

The possibilities
X1600, 6600GT or 7600GT (next month) and overclock the hell out of it
or
latest 7800GS 512MB with 7900 core ($$)

none of the other cards on the market seem to support inverse telecine or Bad Edit Correction (both pretty useful !)

and older AGP cards like the x800, x850 dont have H264 support

Actually, as long as your card supports 10GB/sec memory bandwidth you should be ok without overclocking. 6600GT or X1600 should be fine. No need for a faster card unless you want to do H.264 compression with the GPU... in which case you get faster compression with faster cards.

H.264 is not directly supported by MediaPortal yet and the current graphics card support isn't strictly by custom hardware it's done mostly with the GPU. H.264 support may eventually be extended to older cards but with an X800 costing about what an X1600 does there's no point in getting an X800.
Avivo is the ATi alternative to PureVideo and actually uses slightly less CPU for it's video playback. It has also been rated with slightly better video quality but it's unlikely you will notice a difference most of the time.

I'm guessing when H.264 support is first added to MediaPortal it will be handled by a post recording process in which case real time compression won't be needed so faster cards aren't required but will shorted the post processing time.

BTW, that's if the hardware has direct support for that form of deinterlacing.

thanks for the feeback, but unfortunatley the video card memory bandwidth is only 1 piece of a bigger puzzle. My undserstanding is that DxVA on the correct codec will offload most of the DVB signal Mpeg2 decompression and also the adaptive deinterlacing onto the video card GPUl. Several ppl have feed back the stock x1600 and 60000GT aint powerful enough in the GPU department to handle 1080i in particular. The only positive feedback I have read so far is PCIx 7900 and ATi x850 AGP. I believe some of the newest 512MB 7800GS AGP cards come with 7900 cores so this may also be the best AGP solution. The problem here is cost. This is why I was wondering if any of the latest mid range (read 6600/x1600) cards had been souped up to meet the needs
