Hitfabryk Posted January 25, 2015 Share Posted January 25, 2015 It's probably addressed many times but I can't find it in the archives.. It looks that my card cannot handle XAVC-S and my A7S doesn't (Sandisk Extreme Plus >3-10< 80mbs 32gb) allow me to put in that mode..?.. Do I need another card and should I film in XAVC-S or is AVCHD as good for 1080p? Link to comment Share on other sites More sharing options...
Hitfabryk Posted January 25, 2015 Author Share Posted January 25, 2015 I think I got it, it has to be 64gb at least? Link to comment Share on other sites More sharing options...
richg101 Posted January 25, 2015 Share Posted January 25, 2015 indeed. you need 64gb cards for xavc-s. they donlt actually need to be crazy fast. but have to be sdxc cards.avchd on the a7s is pretty good since it's originating from a full sensor readout. however xavc-s is around twice the bitrate so theoretically it should be better quality. I imagine very few people have done a direct comparison between avchd and xavc-s, and I'd bet there isn't much difference. the fs100 and fs700 recorded to avchd and their images always looked good to me - as do the c100 avchd files.

Ivar Kristjan Ivarsson Posted January 25, 2015 Share Posted January 25, 2015 I read somewhere that XAVC-s files are more detailed and control highlights better. Link to comment Share on other sites More sharing options...

If doing a normal talking head with your camera on sticks in a controlled setting, no one could probably ever tell.... If shooting a long 4+ hour even I would probably use avchd for space saver, but anything short and best image quality I would shoot all my material in the highest form (Xavc-s) Hitfabryk 1 Link to comment Share on other sites More sharing options...

And I have to say I am already impressed after 2 day's trying. Especially the IQ and low light performance. I think I can change my light set in the studio for a more cost effective led light's. And if there is a power problem I could still use candles Link to comment Share on other sites More sharing options...
