HDX900 SD gamma

[Ernie Santella]

No, The HDX900 only records in HD, the SDX is SD. They will never match 100%. As there will have to be a conversion involved. You will have to down-convert the HDX900’s footage to SD and that will effect the process.

Hi there

Yes ofcourse.. makes sense.. dont know what I was thinking.!!!!

Thanks for your time

The real issue is the color space; 601 vs 709. This is reflected in the matrix and really has effect in the matrix off or zero positions. That is to say that there would probably be a good color match between HDX900 in SD gamma and SDX900 where both matrix’s are off. Once you turn on the matrix and “paint” a picture all bets for color match are off. Furthermore the SDX900 gamma would need to be a in similar setting, namely not filmlike, probably most bland setting. The acid test would be to monitor the two outputs on a waveform/vectorscope whilst looking at a DSC Chroma du Monde Chart and observe the match carefully. At this point you can easily make the necessary adjustments to gamma, matrix, etc/

Hi John

Thanks for the info… it wouldnt actually be a case of matching an HDX900 to a SDX900.. more if I could use my HDX900 set to SD… even if an SDX900 has been requested..
I guess the only problem would be they would have to down convert.. if they didnt have an HD player ?

Thanks

You can’t set the HDX900 to SD. It only records HD.

Ok yes I see… I was just wandering if the SD gamma setting was comparable to the SDX900… although the prod co would have the cost of the down convert..

Thanks
