[Q] Adjust FPS on Video Recording

I've searched for this in the past, and I've read the associated threads that come up when I typed in my topic name, but none of them seem to address the issue directly (either it's not what I'm looking for, or nobody answered, and they're all for different devices).
Is there a way to adjust (permanently or otherwise) the fps at which the video recorder records video?
I ask this because I'm looking at my golf swing and I'd like to have as many frames as possible to step between so I can see where I need to improve. 30 fps is good, but it means pretty big gaps for fast motion.
As the Captivate has access to a 720p camera, I'm just curious if there is a hardware limitation that prevents it from exceeding 30 fps. If this is a no-go situation, that's ok, I'd just like to not keep wondering if it is possible.
Thanks for any information.

I don't know much about it but wouldn't you make it better by unlocking your phone's fps (locked at 56fps I believe)?
Just a though.

From my understanding our phone is capped at 56 fps if you see only 30fps on 720p video file that's sure a big file and resolution to handle and hardware wise that is only our phones gpu can offer even if you uncapped 56fps you will still see lower fps(30fps) in 720p video so it is a hardware limitation, for lesser resolution you may see higher fps.

Makes sence, thanks for the correction

Ok, thanks. It sounds like something said in the other thread - I can have higher fps at the cost of higher resolution, or higher resolution at the cost of fps.
Not ideal, but until a physics-bending hack comes along to allow both at the same time, I'll work with what is available.

1080p smartphones and 60fps plausibility?

I dont see a lot of chatter about 60fps recording on the latest batch of 720/1080p recording smart phones.. Is it even possible or just a matter of hardware limitations? Im just curious if we could see a future hack enabling 60fps or do we wait for manufacturers to offer it. thanks!

That would be SICK... But I don't think it'd be possible due to the size of the camera sensor in most mobile phones.

i just know that the HTC Bass (Runnymede) will be able to do 720p recording at 60fps.
afaik, there are no known phones that can do [email protected] currently.

Sounds like James Cameron's dream phone, to me. Cameron is pushing for the movie industry to adopt a minimum 60fp/s for movies.

is 60fps the limit? cant it go any higher?

Really isn't much benefit in going higher except for Video/Sports analysis, TBH. For just watching stuff, 60 FPS is good enough.

I understand that for general recording/watching 30fps is plenty. 24fps even.. Id just be interested for some cool slo-mo effects. even if it were capped at a short time due to the size of the file. Im just wondering if its hardware limitations (video encoding of the chipset, size of the sensor as previously mentioned) or just a matter of software tweaking; forcing the phone to record/encode @ 60fps.
I had an older LG phone that had a slo-mo effect that looked cool but quality took a big hit.

agree
even if games / videos were made to run 60 fps, it's a waste of power
there's no point pushing more than 30 frames when human eyes can barely keep up with less than that

Don't agree at all. The difference is big and is easily proven. Seems to be some kind of urban legend that eyes cannot perceive faster movement than around 24-30fps
Check for example these example videos (using a modern browser on a modern PC).

This is an age old debate and is far more complex than that one example can cover. For video playback where you can't resolve individual frames though, 30 fps is more than enough.
Yes, we all like to see those beautiful bullet time type videos shot with fast cameras, but there are limitations other than processing power. In this case it's optical. The faster you shoot, the better lit the scene needs to be and the better the light gathering ability of the optics. Perfectly easy to overcome when you're lighting the scene and using proper hardware. Not so good when you're using a phone to do the shooting though!

I don't see the point of 1080p/60fps until they can do 1080p/30fps properly
Also better optics before moving onto anything else

Sorry but I don't agree at all, and your post doesn't include one single argument for you statement so it doesn't make any change.
30 fps looks ok, but 60fps video looks more fluid. It is very obvious in fast moving videos, e g sports.
I know that movies are made for 24fps and have "motion blur" to remove the problems with low frame rate, and some people prefere this motion blur (i e movie captured with small aperture) but that is a matter of taste and doesn't change what looks more fluid or not.

HTC Vivid [email protected] http://www.gsmarena.com/htc_vivid-4302.php

That all depends on the GPU. Maybe the powervr sgx 543 can, seems the most plausible of all the GPUs available.

So those can shoot @60fps:
-LG G2
-Note 3
-HTC One (720p only)
Does anybody know more devices?
Maybe Nexus 5 after some camera hack...? I would buy if it had 1080p60

Samsung Galaxy S4 and S5 can record 60fps video as well

Vide recording issues. How can we make Samsung aware?

I'm not sure how to to about this. One thing I really care about on a phone I purchase is video recording quality, more specifically 1080p/60fps and slow motion. Unfortunately, the Galaxy s7 has an issue with both of these.
You know how the Galaxy s7 focuses pretty much instantly when recording video in 1080p, 1440p, or 4k? Well, it doesn't happen in the 60fps mode. The focus is even slower than my s6 in 60fps and there is tons of "focus hunting" where it bounces back and forth between focus as you're recording. Focus is literally perfect in any mode besides 60fps.
Then we have an issue with 240fps slow motion where there are a ton of frame skips throughout the video (just YouTube s7 slow motion videos to see what I'm talking about).
These two issues are huge for me. It's unfortunate because I love everything else about the phone. How can we make Samsung aware of these issues?

Snapdragon or Exynos?

A direct link would help, I'm not finding anything.

I confirm this too, exynos club. Slow focus in 1080 60fps

Does your low-light performance take a hit on the slow motion recording? Because mine does... is this normal for slow motion recording?

Don't see this issue on sd820

Well, i can confirm the slower focus on my G935F (maybe double the time as the normal camera focus), but no skipped frames.

It probably would take a hit as you're using a slower shutter speed to achieve slow motion.

Of course it does. The shutter speed allows half as much light to reach the sensor. This cannot be altered, except to post-process the video on a computer and apply some heavy noise reduction (with the corresponding drop in sharpness).

has anyone a video from the issue? (youtube maybe)

I just noticed stuttering in my slow motion recording..

Many people are starting to tell Samsung about this issue on Twitter.

i have stuttering/jittery in my videos in all modes , they r less in de low reso's but when going higher reso's its gets it alot. the easiest way to achieve the jitter/stutter is moving left/right & up/down with the handset, if your keeping the handset still there's no problem can anyone confirm this by trying ?

The flickering from my flourescent lighting is awful on the slowmo video. This is usually corrected by software so I was very surprised to see it. I'd forgive this if there weren't so many frame drops going on as well. The slowmo video on Snapdragon devices is basically broken. Unfortunately, Samsung has not made an official statement acknowledging the issue. It will require more people to report it.

it seems like 1080p 60fps mode doesn't really make use of Dual Pixel phase detection.. it felts more like contrast detection to me.. there might be chance that Dual Pixel are not supported in 60fps mode.. keep our finger crossed.

Camera App Mods - Suggestions and Questions

Hi Guys,
I'm not a dev and won't be able to any of the suggestions, but just some things I'm wondering from learning how the 960FPS camera works...
Firstly - the camera has a 128MB buffer for the 960fps shooting - this is why it is limited to 0.182 seconds of video (ish). So, two suggestions:
1- Can the camera app be modified to allow lower resolutions? at 720p it will only allow 0.182 seconds, at 480p would this be much longer?
2- Can the camera app be modified to allow lower frame rates? Obviously lower than 240fps is not really productive, but doubling the recording time by making it 480fps would be handy - most useful if you can select which FPS to use etc.
3- Is there any way to modify the app to enable automatic-sequential slow mo segments? One thing you can manually do is hit the Super Slow Mo button over and over again - with a minute delay whilst the cache flushes to the processor and then to storage. Can this be automated? You'd end up with a stuttery video afterwards, but you may end up capturing the specific detail you were aiming for - a water drop hitting the ground, a spark from a firework, a beat of a bird's wings etc.
As said, these are just thoughts, questions and suggestions - I am not a dev and won't be modding the cam app or anything, I'm just putting these out there to see if it's just me who wants them and also to see if there's anyone clever enough to make it so
Discussion encouraged

I also wonder if the 960fps recording is accessible to third party apps.

No way it is accessible, Sony even limited the shutter speed to 1/10s for third party apps, so I say the camera buffer functionality is a big NO for anyone other than Sony, at least for now...

I'm also interested in this - mainly the slowing the FPS down for longer, but faster slomo. The ability to do endless 240FPS would be great.

I think Sony intentionally cripples a great camera/sensor.
I don't understand why Sony didn't include 240fps @ 720p and 120fps @ 1080p.
Then there's no RAW imaging.
I am pretty sure this time also Pixel 2 is gonna crush all the phone cameras with it's crazy camera algorithms.

I know it's pointless to go and shoot stars with a phone but it's so cool if it had features.
Sony Alpha team actually is taking customers serious about features and innovates which is good.

It has nothing to do with algoritms. If you are using a tripod with your smartphone you can have equal or better results. I bet these photos of the Pixel were shot on tripod too.

Slow Motion

Hi there,
Is there a way to change setting time (video slow motion) which is 1,8 seconds, can we do it with APK editor or it takes advanced mode, eventually a developer to do it?
Has anyone ever tried to do it ?
Thank you for your answers.

It's 1/8s, not 1,8. It's next to impossible to tweak it by yourself. And it's probably coming with the update, playing it for 3 seconds in fHD rather than 6 seconds in HD
But who knows if they will update
Leave the request on Sony support website

The recording time for super slow motion is limited by the hardware's capabilities to the 1/8s.

Yup, it's limited by the RAM buffer in the camera. As far as I can tell, we could extend the duration by lowering the resolution down from 720p, but that would look awful, even 720p doesn't produce great results unless there's tons of light. Just as the new XZ2 lineup will have 1080p slowmo but with even shorter duration, because it has the same RAM buffer amount (with the option to go with 720p, though). What I'd rather like is to have the ability to lower the framerate down from 960FPS, that way we could also make longer slowmo videos, for example if we could do ~400FPS, that's still more than enough for a cool shot and would be able to extend the duration. 960FPS is really cool, but not necessary for capturing some cool stuff. It always bugged me that they fixed the slowmo framerate to 960FPS, I'm sure it's possible to make it adjustable via software. What framerate do iPhones shoot slowmo at? 250-ish? And you can make them as long as you like, right?

Hello, may it possible to make 960 fps at 1080p ? It will be great!

Not on XZ lineup, at least for now, we might get that feature after the XZ2 release.
But anyways, why would that be great?
Switching to 1080p super slowmo makes the slowmo capture time even shorter, it is already nearly impossible at 720p to capture the right moment you want in slowmo, 1080p makes it evene shorter and harder. I'd rather have lower framerate and longer duration of the superslowmo than higher resolution. I just contacted sony support about this possible feature, still waiting for the answer. It's stupid to have a hardware capable of recording at 960FPS and not being able to lower that framerate in order to extend the duration of the shot. It's a software limitation and an oversight, nothing more, the hardware is there. It's like Sony saying, "Hey, here's one of the coolest features we ever implemented in a phone. But good luck actually using it because it's damn near impossible to do so. But it's there. Please buy our phones. Cheers." The RAM buffer and the sensor in the XZ2 will allegedly be the same as on XZ1 and Premium. If they can get 1080p super slowmo on it, it's a software modification. And if they can do that, they can also give us the option to switch the framerate. But they don't because higher specs sell better. It's all good on paper, but sucks in practical use.
