HandBrake and Sony AX100.
I use Sony AX100. I don't know HandBrake very well and I'd like to ask a question: I have just created an unconpressed AVI (YUY2) 4K file and now I'd like to create a new file 4K file with HandBrake. I'm insecure if In Framerate (FPS) Option I have to choose 30 or if it is better more than 30. I'd like to get a very good video. I attach a pic. Thanks for some info. Thanks |

As you know from another post you kindly replied to I just bought an FDR-AX100 on amazon for 1200 EUR. With the advantage of hindsight, what do you think of your words at the time, three years ago? Has the technology evolved so much? Not that I would care if my recently acquired camera is already obsolete, because it is good enough for my needs, but I would appreciate your thoughts on the matter. JA |
Re: Sony FDR-AX100
Interesting question Jaime!
Considering that the AX100 is still in the current Sony lineup, that says quite a lot... I was expecting 60p to become "standard" rather more rapidly than it has... still waiting, 5 years looking like the timeline, as 3 has pretty well gone (unless you count the GH5... tempting, but I'm not ready to completely switch systems!). I'm still running a "cheap" Seiki TV, had to make sure it had the ability to turn off motion compensation (firmware update), it's supposed to handle 60p, but I've found the laptops that "should" drive it are hampered by the Intel video chipset that somehow just won't go over 30p, even if they have NVIDIA chipsets available... I'm shooting RX10M2 and M3, which use a similar sensor to the AX100, just a generation or two later, with some minor improvements. Aside from the form factor ("still" vs. "video" camera shape), in my mind they are just a "camera", and capture what I want quite well. The results look stunning, I'm comfortable with the technology and how to get what I want out of it, so even if I have to wish that we had "better", I can't complain! |
Re: Sony FDR-AX100
Adriano...select the "same as source" option for framerate.
Dave, 60p at FHD was and is reserved for basically "home video cameras", as 1080 60p is not a broadcast standard or delivery format. Given that 4K production is mostly for 24p TV shows, and the need for HDMI 2.0 to pass 4k 60p, and you end up waiting for the infrastructure of cheapness to trickle down. I think 60p is the PERFECT framerate, as it works for 720p60, for 1080p60i, and perfectly fine doubling up on 30p 4K stuff. I have never liked 30p...either looks smeared at 1/30 shutter or jittery at 1/60 shutter...a bastard framerate. Paul |

Re: Sony FDR-AX100
Be aware that when using this WB offsetting, you will create an offset to the AWB/ATW system as well. It is a feature/function best reserved for MANUAL kelvin or dialing in after you set an A or B or whatever it's called on the AX100/CX900 series.

Re: Sony FDR-AX100
Dear friends, I post here because all you gave me very good suggestions in past time.
I'm a lonely traveller and I'm using a Sony AX100 for my ethnic documentaries around the world. I shot in 4K ans I make UHD videoediting. The next month I'd like to replace my Sony AX100 with Panasonic GH5. Does anybody use GH5 and Sony AX100? Is there a very improvement in the video quality really? I'm afraid to make an error to buy GH5 for my documentaries. I'm not expert in cameras and I'm afraid to make an error because a camera isn't so immediate and fast like a videocamera to shot. Can you give me some info please? May be it possible to make a good documentary with a GH5 in the bush or in the forest? I mean about its handling, etc. Has GH5 a better steadyshot than Sony AX100? Is it very hard to use the zoom with GH5? I know GH5 comes with a 12-60 mm object. Can you tell me how much is a 12-60 mm focal compared to a videocamera focal (precisely)? Thanks |
Re: Sony FDR-AX100
Hi, Ax100 newbie here. My time readout says that I have 4 hours and 30 minutes of recording time left @ 4K. Someone said that the remaining time display was “optimistic” but I did not ask him to quantify that. How do I relate the remaning time display with how much recording time is actually left? I’m using a 128G card.
Thanks |
Re: Sony FDR-AX100
The ax100 doesn't guess what remaining recording time is, it is what is says and it's correct, the only thing that can deviate is remaining battery life.

Re: Sony FDR-AX100
Thanks!! Simple math should have told me that.

Re: Sony FDR-AX100
Why does the ND filter symbol blink when the switch is in any position other than off when in manual? it actually says “ND off”. This confuses me, because I think the filter is on.
|
Re: Sony FDR-AX100
It is telling you to switch the filter to OFF as it does not need it to control exposure. If you have the filter in any position other than OFF then it is selected for some value ? If you need the filter it will indicate which value to choose to get within exposure range. You can of course ignore it and make your own decisions.

Re: Sony FDR-AX100
Like Ron Says the camera is basically telling you you have a nd filter applied but there is need to do that, just like the camera will also tell you when to use a nd filter.

Re: Sony FDR-AX100
I’m recording a dance recital and the stage lights are LED. I’m watching two cameras, one fixed on the tripod wide and the other does pan and zoom on the kids faces. The pan and zoom is in motion almost the whole time and I look over at the wide shot and adjust in and out. Consequently both cameras are on auto. When I tested out the AX100 the other day the ND filter on 2 seemed to tame the harsh nature of the LED lamps. Even if the scene was moderately lit the occasional spangles on the costumes and white sections of the costumes burned out without the ND filter. My deep skill set is as a sound guy and dance music editor. I just got the AX100 and aside from turning steadyshot on and off and selecting the recording mode I haven’t spent quality time with it yet. I haven’t noticed where I’m told that I need the ND when it’s off.
The ND makes a major, positive, difference in the image. If the camera is telling me it’s not necessary by blinking, what does it really want? I’m not looking for an in depth videography course but if there is a “look here for that, and adjust accordingly” kind of answer that would be great! I really appreciate the help!!!!!!!! |
Re: Sony FDR-AX100
Try the following. ND OFF, Set shutter to 1/60, Set WB to indoor, set AE shift to the dial and set to about -0.5, use manual focus and use the touch focus to set focus once you have set the zoom range you want . That way it will not try and refocus every time the lights go up and down and will maintain the brightness you have set with the AE shift. I find -0.5 to -0.7 is about right for theatre show. If it is on a tripod turn steady shot off. ON the AX100 steadyshot will give you a little more zoom range though but has issues with after movement on pans.

Re: Sony FDR-AX100
When you let the camera handle exposure it will always try to keep the f-stop at it's optimal value which should be around f4, if the camera needs to close the iris further down towards f11 to compensate for strong incoming light it will start to suggest a ND so it can open the iris up again, in this way it will try to prevent to diffraction which can result in a softer image if the iris is almost completely closed.
Indoors you normally don't need to use a ND because those lights don't have the same intensity as the sun but incase you have to shoot with very strong stagelights then just watch your f-stop, if you see it goes to f9 or f11 then it's time to use a ND but I never had the need to use a ND indoors. About whitebalance, like Ron said a indoor preset usually works best for stageperformances but don't expect that to be true for every performance, todays use of LED lights can give you very weird colorshifts where I have found situations that a outdoor preset gave better results, in any case ALWAYS go to the rehearsals and try different whitebalance presets and see what works best, forget about taking a whitebalance on stage because you most likely will get a error as the camera won't be able to take a reading. About the AE shift Ron is suggesting, Sony camera handicams usually overexpose a bit when using autoexposure, with AE shift set to -0,5 or -1 you are forcing the camera to constantly underexpose what it thinks the best exposure should be. By assigning it to the front wheel you can controll the camera's auto exposure behaviour. This is not the same as manually exposing though but it is a good way to controll 2 camera's simultaniously by yourself, the camera will always be quicker to respond to drastically changing lightconditions and with the ev assigned to the front wheel you can correct the camera's judgment if needed. |
Re: Sony FDR-AX100
Wow... Those were fast and detailed responses! One thing I noticed is that the autofocus “hunting” is much more pronounced than my HC-9. Significantly so. When I used the ND on 2 it seemed to be the best image when I was experimenting. I will experiment with the AE shift and other techniques you’ve mentioned. When I set the ND at 3 the focus went berserk and almost never settled, just hunting and hunting. That was OK since 3 was too dark so wouldn’t have used it anyway. I’m about to “dump” a bunch of video into FCPX - is there metadata in the AX100 files that let me compare the image I’m seeing with the settings?
Thanks! |
Re: Sony FDR-AX100
Of course the AF is going to hunt if you have too much ND applied. The camera has to actually be able to see an image to focus on it. And the focus is based on contrast detection, so a really underexposed image isn't going to have enough contrast for the AF system to work properly -- thus the hunting. If you ask me, it seems like a total waste of time not to work on getting a correct exposure first with the camera -- and then moving onto other features of the camera, such as AF, white balance, paint menus, etc.
[QUOTE=Peter Durso;1944196]When I used the ND on 2 it seemed to be the best image when I was experimenting. /QUOTE] BTW, the best ND filter to use at a given time (if any at all) is totally dependent on how much light there is. Each one of the ND filter positions will produce the "best image" under different circumstances. Once you learn how to expose correctly it will be obvious which ND filter is the best one at any given time, and then you won't have to rely on the camera nagging you to change the setting. |
Re: Sony FDR-AX100
Never use a ND3 for indoor stageperformance, in fact, set it to off when you shoot indoors, if your camera, Ron and I say to set the ND to OFF there is a reason for that :)
If you want to know what your camera was doing at a particular moment just play the file in camera and watch the lcd screen, you get all the info like whitebalance, f-stop, shutter and gain, if you have been using nd3 there is a high chance the gain was close to 30db all the time which results in a lot of noise. Also using a ND does not improve autofocus, unless it is used to keep the f-stop around f4, if you play the file incamera where it went berserk, can you tell us what cameradata you see on screen at that moment? Or maybe take a picture of that screen with a smartphone and post it here, it will help to determine what is going on. |
Re: Sony FDR-AX100
Yeah, I get that the ND and other settings would vary based on the individual conditions. Cool.
I will check out the info in the viewfinder when I get back to the studio later. |
Re: Sony FDR-AX100
The other thing I forgot to mention is I set the gain limit to at most 18db. If I know the show I may even set it to 15db. That way you are giving the camera a limited range to operate. When the lights go to black the camera will not try and see in the dark with 30db + of gain and then have to close way down quickly when the lights go up again which will result in it overshooting a lot before it finally decides on exposure.
The other thing is I never use auto focus for a show. Especially for the camera being unattended. I assume you are using it as a full stage camera. Just set up and use spot focus at some point on the stage and then leave it there. I have peaking on so I can see what is in focus. At wide angle all of the stage should be in focus all the time. |
