Xiaomi Mi Mix 2s vs. Samsung Galaxy S9 Video Camera (With Samples) - Xiaomi Mi Mix 2S Guides, News, & Discussion

Ordered both of these devices because I needed a new phone. Since im a videography addict I want to go with the best camera, here are the results from a quick test.
All videos are shot on a tripod in full auto mode and in the following three setups: 4k 30fps, 1080p 30fps and Slow Motion (1080p 240fps).
4k 30fps Sample:
- Crop: The Galaxy S9 is cropped in a lot more (probably due to EIS)
- Noise: The Galaxy S9 shows a lot more noise than the Mix 2s
- Sharpness: The Galaxy S9 seems a bit less sharp
- Stabilization: The Galaxy S9 is rock steady while the Mix 2s shows a lot of jitter (even though both were shot on a tripod)
- Exposure / Contrast: The Galaxy S9 is a bit flatter, while the Mix 2s has more contrast and almost overexposed the sky
- Colors: The Galaxy S9 is less saturated while the Mix 2s was boosted a lot (reality is inbetween both clips)
1080p 30fps Sample:
Crop: The Galaxy S9 is cropped a bit less than the Mix 2s
Noise: Same as 4k, the Galaxy S9 also shows a few compression artifacts
Sharpness: The Galaxy S9 seems a bit sharper here
Stabilization: Both Phones are on par, no jitter or shake
Exposure / Contrast: Same as 4k
Colors: Same as 4k
1080p 240fps Slow Motion Sample:
Crop: The Galaxy S9 shot is a bit wider
Noise: Same as 4k
Sharpness: The Galaxy S9 shows a lot of ugly post-processing (especially on the facade on the left) while the Mix 2s is more natural and keeps finer detail
Stabilization: Both Phones are on par
Exposure / Contrast: The Galaxy S9 has better exposure, Mix 2s is overexposed (Sky blown out)
Colors: Same as 4k, Mix 2s is not as oversaturated as before
Differences: The Galaxy S9 does record Audio and puts out a 1080p 240fps file, while the Mix 2s puts out a longer 30fps file
While the Mix 2s does not have 4k 60fps and 1080p 60fps I am really surprised that it holds up so well. Internal processing seems to be way more intense on the Mix 2s, while the S9 retains a flatter more edit-friendly image.
The jitter on 4k recordings make them absolutely unusable however, while 1080p recording has brilliant, smooth stabilization even when walking or panning.
Galaxy S9 Pro's:
- Brilliant stabilization up to 4k
- 60fps 4k and 1080p
- Flatter, easier to edit color profile
- Way better audio quality
- Pro Mode for Video Recording
Mi Mix 2s Pro's:
- Great internal processing (color, noise and sharpness)
- Sharper, better looking Slow Motion
The Mix 2s seems to be great for people who dont want to mess with their videos afterwards, and keep the edits to a minimum. For my purpose it is not enough atm, but it holds up great against the S9.
Let's hope they fix their 4k jitter and maybe add 4k 60fps.

Thanks for your detailed overview. I own the 2s. I tried recording video with open camera and snapdragon camera apps tonight, and found that the audio was as it should be. Hence, Xiaomi has a software problem to deal with. Techtablets on Youtube covers this as well.

about honor 8 camera

Will i get the most out of its camera in comparison with other phones priced at the same level ?
If you have shaky hands, and you want great quality video and 4k, I definitely recommend getting Oneplus 3. Without ois, you can barely have clear pictures at night, but with Oneplus 3 you can get even with 1/2 shutter speed. In the Honor 8 the 1080p video looks like 720p, and the software stabilisation makes the quality even worse.

Video quality

Your friends are never going to believe what you did. The only way to prove it to them is with that video you took. Rate this thread to express how videos shot on the Xiaomi Mi 9 come out. A higher rating indicates that videos are smooth (and not choppy) and that auto-focus works very well, and that the camera adjusts quickly to different lighting conditions while recording.
Then, drop a comment if you have anything to add!
Coming from a Mi Mix 2S I can not stress enough how great the Video quality is on this Phone. Smooth 60FPS in a 4K Video and very fast and crisp autofocus makes this camera a joy.

The Mi 9 does suffer from judder in 4K 30fps which are a result of missed frames.
This has also been confirmed on dxomark review
Hopefully this can be fixed in a software update

For some reason the videos look worse on YouTube then on my 4K Samsung TV. This may due to the way YouTube processes those dropped frames, during its conversion process.
This needs to be fixed as its a big disappointment.
The Snapdragon 855 has more than enough power to handle 4K at 30fps with AI stabilisation but the Mi 9 lack of OIS could be the reason why it struggles during panning
The video is EXTREMELY SHAKY - EIS seems nonexistant.
- Audio is 14/20 (concert recording ok, quieter scenes a bit less nice)
EDIT:
- This is due to limitations on 4K60
- EIS is good on 4K30 - but then there are dropped frames.
I dislike the EIS implementation of Xiaomi (so called stabilization) on the Mi 9. It crops the image and you loose sharpness over stabilization. If you turn it off you also have a wider view.
My other phone (Mi 9 SE) the EIS is less agressive, so the crop is less perhaps due to the lesser cpu. The actual image looks better because it is sharper, detailed and has a wider view. The problem is that EIS causes judder when panning because the software is not optimized and more judder with lesser cpu. I actually prefer that they implemented the EIS on the Mi 9 with less cropping.
Strange is that I disable stabilization on both Mi 9 and Mi 9 SE but the video is still sharper and more detailed on the Mi 9 SE.

To be noted that now Gcam supports EIS in 4k 30 fps and 60 fps with much less cropping.

The stabilization is not as slider smooth as MIUI cam, though. I'd still prefer to disable EIS and have my gimbal for serious video recording.
Its excellent actually thanks to the new GCAM mod by urnyx05. It supports 100Mbits 4K 60fps videos with working video stabilization!! Working video stabilization on 4k 60fps is really uncommon. Non of the flagships have it nor even iPhones support it.

Actually, many of today's flagship can stabilize [email protected] including but not limited to iPhone 11 series, Samsung S20 series, even OPPO Find X2 Pro can do it as well. Xiaomi isn't left behind as Mi 10 series can do it, unfortunately as typical Xiaomi, they don't backport many features to older devices.

Hi, can you please point out which version of the GCam you're talking about? I've been looking for ways to get at least 1080p 60fps with EIS on my Mi9 but no luck so far..

IMX586 Sensor 4k and 1080p @60fps or not?

So I got my Xiaomi mi 10 ultra and I love it.
But what I don't understand is that sensor under the telephoto 5x lens.
It is an Sony IMX586 which is a pretty decent Sensor. I am happy with the picture quality so far.
But video.. something weird is going on here:
In xiaomis camera App i was not able to make 4k or 1080p 60 fps videos with the 5x tele.. the smaller, not as good sensor of the ultra wide (12mp got no more specific info) is capable of 1080p60.
The IMX586 is a good sensor. Other phones are using 4k 60fps with it. Even a new Drone got the sensor and is capable of 4k90fps.
Why is xiaomi not letting me film in 60fps 4k or 1080p?
Is there a way to get this work in gcam or ultracvm?

How is the image quality between 2x-4.9x zoom?

Has anyone come across any detailed review / analysis of the main len's image quality when zoomed in? I'm a bit concerned it might not perform as well as other cameras that have a tele lens that starts at 2x or 3x optical zoom. The tele lens on the N20U doesn't kick in until 5x optical zoom (or I think there was a bug where it doesn't kick in until 10x zoom?)
It's a digital zoom. What do you think?
Sent from my BlackBerry Bold 9900
2x - so, so. 4x - clearly digital and pixelated (especially, when recording videos), 5x - great (both video and photo), 10x - very good, almost like optical, 20x - pixelated, not good for serious things, 50x - just for fun, pixelated artwork.
I m highly disappointed as I thought everything up to 5x should be optical. 5x is great but sometimes we just need 2x.
I am also disappointed in 108mpx camera as no optical zoom/ultrawide is available in this option plus image quality is worse than standard 12mpx camera. So not sure why Samsung did like this.
The same thing with video: we get ultrawide/optical zoom only in 30fps mode. No ultrawide/optical zoom in 60fps mode, only digital zoom, which is very disappointing.
However, putting these issues aside, both photo and video cameras are just great, pictures are crisp, quality is very good even during night time.
I wonder if it would be possible to unlock optical zoom/ultrawide with 60fps mode...

Question Camera and Video Recording questions

So far liking the new 7p, havent seen any crazy battery drain or anything yet.
Camera can shoot 30x pics but only 20x video... any idea why? Tried changing settings (1080p, 30fps) to no avail.
Wonder why we cant shoot HDR in 60fps either...
Can the 6p do these?
Thanks
Likely due to lack of light and/or processing power. The 7 Pro uses the telephoto lens that can do 5x and 10x with a 1:1 crop. Everything between or beyond those steps get processed with data from the main sensor and the new Super Resolution AI. Considering it can do 30x for a single frame. Mediocre 20x for 30/60fps is seems fine for video.
I am also miffed about not having HDR at 60fps especially since we can now do full zoom on FHD/UHD unlike the 6 Pro getting locked out of 60fps for UHD 4x zoom.
