[Q] Why cm10 camera cannot record at a constant 30fps?

Why cm10 camera cannot record continuously at 30fps?
be it 720p or 1080p.....frame-rate always drops in low light.
I want a camera which records at 30fps continuously irrespective of the lightning conditions...the same way we had on stock.
Why is fps issue there?It is similar to the one on HTC devices where fps drops in low light.

its normal behavior for lowlight conditions to have longer exposure shutter times during filming with small lenses in mobile phones

then why does it not happen on stock ROM?with LG stock cam flashable mod on CM7..continuous 30fps is available.then why not on CM10?
developers is it possible to make this happen?

i have used the moded stock cam by AndiCP on GB before to and it should be just a matter of time to have this for ICS roms

higher fps @ night = darker videos.
There is a simple explanation here. The lower light means there is more noise in the video. With more noise the encoding engine has to put far more effort to get the compression it needs. However with low light unless the encoder has a denoiser the encoding engine has far more noise to deal with than normal conditions.
If you want a more technical answer: More noise means that the motion-estimation engine of the encoder is thrown for a toss. This is the part that consumes maximum CPU cycles. Hence the drop in CPU cycles.
There is another aspect here: The more the noise, the worse the compression and hence even other parts of the encoder are basically crunching more. More bits are generated which means that the encoding and entropy engines are also crunching more and hence the worse performance.
Generally in high end cameras a lot of noise is removed by the imaging pipeline in the sensor. However don't expect that in a mobile phone sensor. [This is the ISO performance that you see in DSLRs ].

I know that mates.
I don't care about dark videos or more grainy video
since in lowlight or "not the brightest conditions" anything below 30fps isn't pleasing to the eyes...especially fps of 15fps is a joke.
I'd rather have 30fps while sacrificing a bit of quality.
since the cm10 camera doesn't produce any super awesome video in low light by reducing fps

[Q] Video - Slow Motion quality

Question guys - to enable you to slow certain scenes in a video you need to select the slow motion video scene...fair enough.
Should this in turn reduce the quality of the video?
I could be wrong, but before I went to a custom ROM, I am fairly sure the video quality remained the same as normal. Now as soon as I record in slow motion, it reduces the quality.

hello there
yes it will reduce the quality ...
best regards

I noticed that too with mine. Horrible isn't it? You also get reduced quality with 60fps. You get verticals lines. I gave up and stuck to 30fps.

I also have this problem vertical line appear in indoor environment. However, customer service told me this will be fix in next update.

Slow Motion = Low Resolution
I saw that HTC video doing a slow motion video of a man doing fire/flame stunt. Actually I was amazed and got excited that I wanted to try that Slow motion on my own with something else like a sprinkler maybe.
So I found one at a park and as soon as I started shooting the video (slow motion video under video settings) WTH!!!! The resolution dropped to something like 768x432 and its a bite pixellated, not true HD (1080p) which I thought I'd expect just like from the HTC video... Yes you can trim/edit the video that's cool but I was hoping for 1080p HD quality
I hoped HTC would come with an update that can maximize its camera features up to 1080p resolution. oh well..

Well I guess is impossible because the Snapdragon 600 doesn't support the record of 1080p videos at 120fps :\

I'm on stock 4.2.2 and I've recorded this slow motion clip a week ago (don't forget to turn on HD when viewing it). The quality seems fine to me.

Yeah. The quality is awfull. The slow motion video from the the device with the man in the night eith fire from his mouth is years ahead bettrr than the ones we can record... But why HTC ?!
Sent from my HTC One using xda app-developers app

some info on this please?
hello guys. i'm sorry for this little derailing question but it was the only thread i found:
i'm currently digging into slo-mo available in latest phones.
i just saw some HTC ONE samples and i was very disappointed from the low resolution.
i was particularly impressed with the new Iphone 5S 120 FPS real 720P feature. it really looks 720 and not upscaled like the fake 720p NOTE 3 slo-mo. however i cannot use iphone anymore due to the small screen.
so from this thread i gather the faster frame limitation is by the processor itself? (snapdragon 600-800? what's the 720P limit?)
i am willing to wait until an Android phone will have a usable 720 slo-mo..
so what hardware could provide this? as i can see nowdays, the latest android phones cannot do it (not the NOTE 3 or the G2 which doesn't even have slo-mo to begin with).
my choice now are either wait for a phone that will (maybe the next HTC?), or wait till apple make a bigger phone (cannot stand the small screen).
your thoughts on this?
thanks.

Record with your nexus 5 in 3264x2448 (almost 4K)

Since the release of Lollipop Google introduced us new API for camera and that feature is really epic. Developer Chih Mao Chen made camera app for lollipop in which our phone nexus 5 is able to record in almost 4k resolution.
Download Android L camera app here:
https://github.com/PkmX/lcamera/blob/master/lcamera-debug.apk?raw=true
Note: all credits goes to developer who made this app, I'm only sharing this with you guys and sorry if this is already posted.

[QUOTE=Isus um there isn't anything there

Works fine for me.

Is the quality difference significant?

Low FPS for sure . and no it doesn't look that good .. Too much noise

For me its very crisp, sharp. I really love it, and it really surprises me that N5 camera can shoot 4K videos

This is a Duplicate thread!!
Below is the original. All discussions are ongoing there. It would be more helpful if all interested members can discuss there[emoji4]

It doesn't for me. It's probably the camera that worked fine on 4K but the snapdragon 800 SoC that couldnt handle 4k Probably.

It works fine, you need latest lollipop for it to work

Use manual exposure and it records 30 FPS for sure.
Also, Snapdragon 800 does support 4K, it's the camera that doesn't (3264x2448 is 8 MP, 4K is 3840 x 2160; not enough horizontal pixels).

But still it's pretty amazing resolution. Our **** camera just got better.

Patch for 60 fps recording?

Is there any patch to enable 60 fps recordings on Nexus 6?

My question is not for 60 fps, how the heck can this camera improve.....it sucks badly. Poor focus on it. Good phone,bad camera

Poor focus?
Is the only one that it can enable manual focus!!
The other thing is that you dont want to buy any good camera app!
Try cinema fv-5 and camera fv-5
Or open camera!
But I want too the 60 fps patch!

From my understanding the camera is capable of at least 60 fps and it is really the software side that is lacking. (Someone correct me if im wrong please) But i havnet seen or found any way to improve the Frames per second.

240 FPS 720p

Is there a way to enable recording of 240 FPS slow-mo? I really do not mind the video being at quality of 720p, If the phone is capable of 1080p @240, I do not see a reason why it would not handle higher framerate at 720p.

where did you find info that it could handle 240 fps? i thought it was more like 60 (or 120 for 720p max)? don't get me wrong, i would like to see that, but imo this is out of A2's reach.

It records video in 1080p at 60fps or 720p at 120fps.

The 660 chipset on the Mi A2 IS capable of 240FPS @ 720P.
(https://www.qualcomm.com/products/snapdragon-660-mobile-platform)
The limiting factors here would be either A.) the camera modules or B.) software implementation.
So, in theory, yes but further testing/research would have to go into determining the possibility.
This would best be a question for Xiaomi support:
https://www.mi.com/global/support/contact/
Good luck!

and C) the willingness of Xiaomi of course

^^^ Absolutely this. LOL.

Even Mi 8 lite has 240FPS @720p, it uses the same CPU, so it is a software matter, so there should be a way to enable it.

@ond96
And you're likely right but, as of now, no one on XDA has volunteered to implement such a change.
Please contact Xiaomi and inquire further with them.
