V4HD + hdmi 2 sdi + HD express / need advise

Hi dave!
Here is Andrés from mexico city.
i have the v4hd and im more than happy with it, i write a story and send to motu since ias far as i know is the first v4hd working in mexico.

i need and advise on the following. since day by day more project are being shoted with 5D and 7D from canon and im workin as location video capture with P2, RED, EXDCAM im looking for a way to ingest video from those cameras.

both 5D and 7D have hdmi output that is HD only in passive mode, not when recording, but anyway if im capturing with motu i think is gonna work.

for that i need to buy an hdmi to sdi so i could use my v4hd. the hdmi to sdi is around 450$ but now im reading a lot about HD express ($500 with express card)

so, whtas youre advise, to buy an hdi to sdi and use my v4hd or buy and hd express?

for me is amazing that hd express could work with uncompressed HD, my guess is that that capability is disable when running it on mac book pro right?

and a questoin about hd express. it need Dc always or when operating with laptop coul be powered by the express bus?

thats all.
will be waiting for youre advise.
bests!

ok! why motu hd express cant be operated with bus powered? like motu traveler or the other audio devices that are firewire powered?

maybe motu need to work on that, cose is like a canpus but better! and is gonna be better if it can be bus powered

Hi Dave, i buy it from bh so it will be with me during the following weeks.

the last question. can i run hd express using 12v camera batterires? if yes can u tell me what i need to llok for in batteries for not damaging the motu.

bests!
