Questions about the Sony AX100 for a documentary

I have a tight budget & I found the Sony to be attractive since its basically all in one. At least good enough to shoot a trailer for crowdfunding... I hope which is why I'm asking for your help.

Its a trailer for a documentary. It will not be shot in ideal situations most of the time. It will be some run & gun. There will be interviews too (with my limited experience I'll be doing voice overs for that). Would this camera be good enough to make a trailer?

I would like something cinematic, how much can be done in post with the footage? Meaning, I've read that you can take 4K 8 bit 420, down-sample to 1080p 10 bit 422 and produce really nice looking footage. Is that true? I believe that the look of the film should be as good as the story told.

Thanks in advance for any help.


4K 8-bit 4:2:0 can be downsampled to 1080 HD 8-bit 4:4:4, which gives you a lot more color information to work with, but it's still 8-bit which is fine if you are careful how you light and shoot your video.

The Sony X70 camera shoots 10-bit 4:2:2 color and will have a 4K upgrade coming next year. If you can afford it, I would look at buying the Sony X70 camera. ( it does not cost too much more than the X100 )

Thanks Guy for the tip. You're right, it is a bit more but not by much with some great features but right now I'm looking at doing something I can post on the internet for crowdfunding. Do you know how much the upgrade will cost? And when its coming out? Thanks again for the reply.

Sony hasn't given any cost or timeline for the 4K upgrade, but I would expect it to be around $300 and should ship by Spring 2015. The X70 camera is still very useable as a 1080 HD camera, with the 4K being a nice upgrade next Spring.

I wonder if the AX100 will get some type of upgrade then as well or is the X70 just that much more expandable?

The AX100 is already 4K, so there's nothing to upgrade, where the X70 is a 1080 HD camera that will have a 4K upgrade next Spring.

Thanks Guy... guess I meant will the X70 get a 10 or 12 bit 4K vs the 8 bit of the AX100? If it does, then it would be a buy for me, if not, then the AX100 looks better for a minimal investment to make a trailer.

My guess is that it will shoot the same 10-bit 4:2:2 color format after the 4K upgrade.

10 bit in 4K or 8 bit in 4K like the AX100 has. Since the AX100 already does 10 bit 422 in 1080p. Thanks for your patience! It will be my last question.

>>>10 bit in 4K or 8 bit in 4K like the AX100 has. Since the AX100 already does 10 bit 422 in 1080p.

Actually the AX100 can ONLY record in 8-bit 4:2:0 formats, so the only way to achieve higher color fidelity is to downsample your 4K footage to 1080 HD and you will be able to achieve 8-bit 4:4:4 color. ( just like you can with 4K GH4 footage )

10-bit 4:2:2 recording is one of the main reasons why the X70 camera costs so much more than the CX900 does. ( and why the 4K upgraded X70 will cost more than the AX100 does )

Also, just saw a pre black friday sale selling the AX100 for $1699 @ Abe's of Maine.

Only reason I mention the price drop is that it now the same price as a GH4.
