The slow video, when done correctly, is awesome. those Asus Zenfone 7 Pro sl-mo understands how dangerous video can be.
Until the last decade, large, heavy and expensive cameras were needed to capture slow video. However, smartphones have had slow capabilities for years. Heck, recent Huawei devices 7680fps video can be shot – albeit in high quality. As frame rates increase, quality generally declines. Quality degradation can come in many forms – resolution, angle reduction, frame interaction, and high compression.
A typical smartphone can shoot at 720p slow motion at 120fps. A flag can shoot at 1080p 240fps and 720p 960fps. If you want to shoot Ultra HD 4K, you are usually stuck with 60fps even on high end smartphones.
The Sennheiser 7 Pro can shoot 4K video up to 120fps – that’s awesome.
Our verdict: Asus Zenfone 7 Pro Review
How does it work?
Above are some of the slowest videos captured on Asus Zenfone 7 Pro. Let’s take a look at the clip set in the order shown in the video.
First, I shot a video of me practicing football free style. The light is a bit challenging when the sun shines through the trees, as there are shadows under the high walls and fences. With the right colors and constant exposure, these scenes look sharp. There is a bit of noise where the light falls on the right side of the photo, but for slower scenes this is very detailed and sharp.
Next, I kicked a bit of sand on the beach to push the detail-solving capability of the Sennheiser 7 Pro. You can easily see how a single sand grain flies over the beach. In this clip, the phone had to be exposed to very strong sunlight. As a result, my shorts and shoes almost crumbled. There are still details on the fabric of both, but not much.
These slow scenes are very detailed and sharp.
Usually when shooting on the beach you can create ripples on the beach and in the sand. Highlights have not disappeared from the sky. You can still make clouds, and there is even some detail and color in the factory and the surrounding trees. This was the most challenging film to capture due to its huge dynamic range. But Senfone still managed it. Very attractive!
Next, I gave up SD card On my desk while holding the phone in my hand. This is low light, so you can see the noise and noise reduction artifacts on the desk pad and the SD card itself. Since the shutter speed must be low to get more light, the slow motion is not so crunchy.
When the water flows from the taps below, the video is sharp, but the phone is not able to capture views as fast as the water is clearly visible. 120fps is not enough but switching to faster frame rates gives worse looking scenes. This low resolution video is similar to what we used to see on other smartphones and although it is adequate it is not as impressive.

Zenfone 7 Pro: Taking Slow-Mo Video to the next level
It’s amazing to see such an advanced feature in a € 799 device when there are not many other expensive phones. We dropped this feature when we launched the phone. After some practice during the review period, we decided to dive deeper and push to its limits.
The Ultra HD 4K 120fps slow motion is a continuous shooting mode, not an explosion. This means that you do not struggle to report on time. I took a 25 minute Ultra HD 4K 120fps video and the phone was warm but it didn’t bother and it didn’t shut down.

In general, you are more likely to shoot short slow videos, because the final product will be slower. I shot under different conditions in daylight, low light, outdoors, indoors, portable and in a triangle.
Data ratio is a critical factor for video quality. In general, the higher the data rate, the larger the files and the clearer the image. Since the Sennheiser 7 Pro comes with 256GB of storage, the previous one should not be a problem. Sennheiser 7 Pro shooting ~ 120mbps Views are very high for average smartphone videos and are around 50-80mbps. This high data rate video means that the slow files are very clear and crunchy when you consider the ones that came from a smartphone.
You can reduce the views to 120fps slower using the phone’s gallery app. This makes it easy to post slow video to social media. By default, the video is not verified. This means that if you upload it to a computer, you’ll get a full resolution and full – time real – time clip with audio, so you can slow down to match the project’s frame rate. However, it should be noted that this mode locks you from using the primary camera.
Asus’ discreet camera phone knows how dangerous slow video can be.
Overall, the Sennheiser 7 Pro Ultra HD captures 120fps slower video at 4K resolution. The scenes are sharp and this frame rate has an amazing dynamic range. The phone is doing some serious work to get this usable look. It has some of the best continuous 120fps slow scenes we have seen on any smartphone – captured in 4K to get started.
With the slow motion of 1080p on Samsung, Apple, Google, Huawei and many other smartphone brands, Asus’ discreet camera phone offers a little more for those who want to experiment with slow-mo movies without having to buy a fancy item. D.S.L.R..
