video recording quality

Hey guys, the camera seems pretty good on this phone when I'm taking pictures, however when I am taking videos it almost seems kind of grainy even though its suppose to be 1080p. Anyone else have the similar or different experiences? Please share!

Grain doesn't have much to do with resolution. What affects grain directly is light. Low light will give you more grain. Period. This is valid for professional cameras as well.
Shoot a video I good light and the quality is excellent.

Don't use 1080p it's crap and makes videos look awful. They decided to zoom the picture in about 40-60% and not allow you to zoom out. As a result everything looks grainy and out of focus.
Set ur camera to 720p look at how much you can see, how clear the image is how sharp the colors are etc and then switch to 1080p and you will find all the sudden you zoomed way in and can't zoom out and the picture quality dropped about 60%.
They claim 1080p support but it's a lie since they zoom in and give you a MUCH lower quality video than 720p does.

How do you switch to 720p mode?

I'm pretty sure that's just a big nasty bug. The camera sensor and chipset are all very capable of 1080. It seems like the 1080 is zoomed into the amount of area that 720 would take in the middle of a 1080 image...I won't say it's an honest mistake, as it's borderline retarded...but, if it is dumping 1080p worth of data it can certainly do 1080p video...that's only 2mp and the tough part is writing that to storage without it getting skippy...and clearly that can be done.
Though I am assuming it is writing a 1080p file...has anyone checked?

GoPro HD also does this. Few of my friend's digital point and shoots did this as well. So, it's a sensor issue, not a software one.
I posted this before:

I really wish there was a way an external microphone could be used while recording video.

My problem is with the recorded audio. Has anyone found an app that let's you control audio gain. Serious clipping for live music records.

Its the quality (bitrate) in which the audio is recorded. At stock, its set at 64kbps and a sample rate of 44kHZ which is pretty subpar.
There's a hacked camera apk that lets you record audio at 194kbps with sample rate of 48kHz and also raises the video bitrate by a tad as well.
A tremendous difference in quality.

The graininess is caused by poor lighting. I went to sea world with my girl this week and all the outside video's came out amazing. But, inside shots with low light all came out very grainy. I can't blame the sensor too much because like someone mention before the same happens on high end camera's. But, also remember professional shots are taking with very high end lighting equipment.

I can't seem to find anything like what you're referring to anywhere in the market or our app section. Got a link or a file name? Thanks.

Does 1080p video look better than 4k from the G4 camera?

From my understanding, 4k video from the G4 has very low bitrate. I took two comparison videos on my phone, 1080p vs 4k, and it seems like the 1080p looks quite a bit better. Anyone know the bitrate comparisons between the two?
I'm wondering if it's wise to just keep my video settings set to record only 1080p and not even bother with 4k.

To me the 4k looks better then 1080p...

4k looks better than the 1080p, but the 4k still doesn't look great on my 4k monitor on my computer. The computer has lots of pixelization, and playback looks like borderline buffering. The computer has plenty of horsepower too.

LG V30 (H930) able to record 1080p at 120 fps

Hi all.
I've been able to record in 1080p resolution at 120 fps through app called Ultracorder. As a bonus is encodes in H.265 codec which promises half of the byte rate when compared to the H.264 with similar quality.
Not sure if possible in free app (you can try) but I've been using paid version which after latest update allows to change fps and surprisingly I can set 240 fps (although it looks like 120 fps with doubling of the frames to reach 240).
Video looks super smooth and crisp when played at 25% speed.
No luck with higher resolutions, only 30 fps available :crying:

Looks like the 120fps on FHD is legit as there's notable difference when slowing down the vids on 60fps and 120fps. But the quality is still kind of bad lol. BTW Thanks.

Shame this phone is 2 generations ahead of my Nexus 6p but my Nexus 6p can do 240fps slow motion but the V30 appears incapable

I believe the stock camera app is recording 240fps at 720p. But in a very very bad quality and cannot zoom. (Quality is worse than the sony recording 960fps)

Thanks for your post, I downloaded Ultracorder as well and made a video comparision between slow motion modes which I uploaded on Youtube and I´m not allowed to post because I have <10posts.
The internal slow motion camera always records on 720p 240fps with no options of changing the framerate, but you can choose the normal and wide angle lens. The wide angle lens footage looks worse than normal lens though.
In the Ultracorder App you can also choose 1080p with 120fps with the normal lens. It works fine and enhances the quality a little bit.
You can also choose 1080p 240fps but if you record with that setting, you get a file with 160fps and dropped frames. I thought maybe the memory write speed was too low, so I also tried recording it on my Sandisk Extreme MicroSD with the same result of 160fps.
In Ultracorder you can max. choose 30fps with the wide angle lens.

Are you sure this is true because my Nexus 6p actually gives you an option to choose 240 for slo more and it looks a lot smoother than the V30 slo mo. I'm pretty sure V30 only shoots in 120fps

Yes, the footage is 240fps you can choose the playback rates
1/2
1/4
1/8
directly in the LG V30´s media player while
1/8* 240fps= 30fps playback rate
Also I inspected the file in windows and it was 240fps. My V30 runs on Android 8.0 security patch 1.9.18 I just received it yesterday

I realized why. Shooting in regular camera produces 240fps while shooting in wide angle mode only does 120. I'd been shooting slo mo in wide angle only.

And for some reason the new GCam (and the mods based on GCam v6.1) kinda ends up recording 1080p240 instead of 720p240 when you set it to 1/8th slow motions speed.... Even though i ONLY have a 720p240 entry in the media profiles, otherwise only 1080p120...
Playing that video then (which is generally already pretty damn dark) is also kinda laggy, so either camera or SoC arent capable of that

Could our lack of 1080p240 possibly be due to a hardware issue such as the write speed of the storage medium in use, or the method of connecting the camera to the SOC? I was thinking largely of these being essentially a computer at it's core, and if the storage devices aren't on a fast enough bus, it could lead to dropped frames. My other thought is if the camera is connected to a slower bus, then it would result in frames being dropped due to not being able to get the data transferred off the camera fast enough. Essentially a lack of bandwidth issue...

Video camera problem

I looked at several reviews of a50 and a70. All video examples has a problem. Autofocus can not find the optimal setting, so the video is jerky! Most bloggers did not pay attention to this moment! But this is not normal for a $ 485 phone. What do you think about it? Are there owners of the device? Maybe an update has already been released that fixes the situation? Example in youtube 6-iwSS_hX0Q in 5:37 (sorry, i cant permissions for publish links)

Yes,seems to be issues with the cameras,no EIS as far as I know,the 32mp lens uses software to account for only really being 8mp. Im not a camera guy so don't know that much about it but most of what I've seen and read indicate the cameras aren't that good

Thanks fo reply! I means video camera only. Photo camera, in my opinion, is not bad. But the video, which is approaching, then moving away, is a real problem. I'm not ready to give $ 500 for the quality of the video, as if my hands were shaking. But I expect that the problem can be solved in one of the updates.

This is a stabilisation issue I think, not a focus one. Ideally the camera software could do some work to stabilising 1080p video using the spare/latent area from the 4K chip, but it would still require some heavy processing which perhaps the chipset is not up to?

May be, I incorrectly described the problem when I said about shaking hands. The frame in the video is approaching, then moving away. Then approaching again. That is looks as the zoom is not fixed. Poor stabilization may be an indirect cause of this behavior. That is, shaking may interfere with the correct setting of autofocus. But I am convinced that the actual reason is poor autofocus.

It's really simple.
4K video = no EIS
1080p video = EIS
As you can see in this review https://youtu.be/rwrDrG23gRA?t=344 (5:43) stabilization is just fine.

That's what I was hoping (see my last post). Good to see someone showing 1080 recording while walking, which is sufficient for most users I suspect. To get stabilisation in 4K you either need a much larger raw chip resolution, or optical stabilisation (probably not on mid-range devices).
Andre

Here's another A70 1080p rear camera video, he tests many scenarios. Looks OK to me for this price range https://www.youtube.com/watch?v=4ju52xFjYz4
If you need to shoot a lot of high quality videos then get S10 which is twice the price. Mid range phones will never have camera as good as high end flagships, that's just impossible.

I'm not sure still. My example in start post shows 3 shooting modes:
1. 4k
2. 1080p
3. 1080p Wide angle lens
3rd shooting mode gives good quality only. The second mode is also a little jerky
p.s. I think, my xiaomi mi5 probably did not have that problem. But i just can not check it now. So I am unpleasantly surprised by this effect

Wider angle shooting always makes shots look steadier, regardless of any other technology. The more you zoom an image in, the more any camera shake is exaggerated.

Question Can the Oneplus 11 change from ultrawide to wide when shooting video?

Looking to buy this phone and can't find any info online if it can seamlessly change lenses while shooting video. Also the ultrawide camera can record 4k30 right? there are some videos out there saying it can only shoot 1080...

Ultra wide 4k30 possible.
