some canon xh-a1s observations

I've been playing with my new xh-a1s for a couple of weeks now, playing with various configurations, and I thought I'd share a few observations. Some of them are things that are probably obvious to most advance users, but a lot of these issues are things I searched for through different forums, couldn't find, and finally had to just learn through trial and error.

1) The out-of-box preset is garbage. I played with about half a dozen custom presets in various conditions, including Panalook, VividRGB, Vision, and others. The best one out of the bunch finally ended up being "TrueColor." I found a lot of people complaining about this custom prest producing too much blue, and I too saw this problem - until I performed a custom white balance, which made everything perfect. To perform the custom white balance, I simply held a piece of plain white printer paper in front of the camera while outside, hit the auto white balance button, and voila. Same thing should be performed under tungsten/indoor conditions as well, on a different white balance preset (there's an "a" or "b" option switch on the side of the camera). If you choose to use another custom preset, be wary of the fact that the CineGamma modes seem to be different between the Xh-A1 and the Xh-A1s, and you'll have to compensate in some way. This isn't an issue with the TrueColor preset because it doesn't employ the CineGamma mode in any way (set to off).
2) I kept getting grain/video noise in my early footage under various conditions. I eliminated this completely by flipping the AGC switch to "off" and making the menu preset for the "low" gain setting "-3db".
3) I kept noticing a significant quality difference between my indoor and outdoor footage, even though I was using sunlight for both. The indoor footage was crisp, gorgeous, while outside footage was foggy and looked like SD rather than HD. I finally narrowed this down to shutter speed. Running 1/48 while outdoors in bright conditions is no good. When shooting extremely bright conditions, I got the fuzz when on 1/48. I cranked shutter speed as high as 1/15000 on an overcast day, and the results were night and day. I started getting the crispness that I saw in a lot of the YouTube demo videos that had inspired me to buy this cam to begin with. I basically started making it a rule of thumb to raise my shutter speed as high as I could go while still getting light with my f-stop at around 2.xx. Great results (so far) but I'd love to hear from anyone who advises against this for whatever reason.

Hope this helps the introductory xh-a1 or xh-a1s user.
 
Good one about the shutter speed. Mine is permanently on 50. In bright conditions I throttle back with the ND filters. At tomorrow's wedding I'll try increasing shutter speed instead when I'm not concerned about the bigger depth of field and look forward to the results.

I sometimes get caught out on longer clips where the light changes, if I haven't chosen the right ND filter the iris can close completely as I twiddle the ring to maintain exposure - so annoying to spoil a good looking clip!
 
I just got my xh a1 2 days ago an can relate to everything you said. With everything setup As you mentioned it can be a real gem of a camera. I was using 2 Sony hc1's before this and the diff is night and day better!

I read this in a review ...

There are options which include white colour balance adjusted from 2000K to 15000K.

Is that a new upgrade on the A1S ..?

Cheers.
 
Not sure if it's new to the XH-A1s since I never owned a regular XH-A1, but yeah, there's an option to choose the color temp on the "s" as described above.
 
No, it's not an upgrade, its on the old XH. Were talking the Kelvin switch under the LCD, which turned the shutter dial into a color temp (K) dial right? Ya, its there.
