Tips to Convert Videos to the Best Format

Do you want to convert your video to the ‘best’ format for a particular device or platform? On the surface that may sound easy, but how do you identify the best format – and what should you look for?
While there are several ways that you could find the best format and convert your videos to it, these tips should help make it a lot easier:

• Make sure the format has hardware support
  
  For a video to be played, the format needs to be supported so that the device or platform it is viewed on is able to decode it. However that decoding can take place either using software or hardware.
  
  The problem with software decoding is that it requires a lot of processing power – especially for high quality videos. That is why as a rule the ‘best’ format should always have hardware support.
  
  
• Factor in the compression
  
  Part of the video format (i.e. the video codec) will dictate the type of compression that is used to encode and store the video. Newer formats normally have more efficient types of compression, meaning that they can compress the same quality of video to a smaller file size than older formats.
  
  As you can imagine this is an important factor because the ‘best’ format should compress the video to the smallest file size possible while maintaining its quality. However it is complicated by the fact that it takes time before devices have hardware support for newer formats built-in.
  
  
• Try working backwards based on how the video will be used
  
  Instead of trying to identify the best format based on its hardware support and compression, you could work backwards based on how the video will be used. For distribution formats such as MP4 with H.264 are the best option, and the same goes for online videos.
  
  In general MP4 with H.264 is a ‘safe’ format for most devices, but you could check if HEVC is supported seeing as it has better compression rates.

See how these tips can help you to convert your video to the best format? Once you’ve identified what it is, all you need to do is use a video converter to switch your video to that format. For example you could use Movavi Video Converter to convert QuickTime to MP4, AVI to FLV, MPG to MKV, and so on.

Regardless of how you approach it, following these tips should help you to end up with a format that has the best possible compression while still supported by the hardware of the device it will be played on. That is as good as it gets, and should allow you to enjoy high quality videos without taxing your processor (or storage) too much.

Android Version of Chrome could be leaking your information

Android is the most used software system around the world with over 2 billion users worldwide. The immensely popular, Android comes with a number of pre downloaded apps that users can get their hands on after switching on their phones. But now as news of a flaw in the software causes many users to start losing faith in Android, here’s all we know of the problem so far….

The problem has to do with the Android version of Chrome which is the most used browser on Android. Security experts associated with the problem have said that they have found a shock issue relating to the Android version of Chrome.

More on the issue associated with the Android Version of Chrome: 

Experts up at the Nightwatch cybersecurity have said that there is a shock issue with the Android version of Chrome. This issue could potentially lead to the popular browser leaking a phone’s information. Information such as the firmware model of the phone, security patch level and hardware model are all susceptible to the leak.

The Android version Chrome is not the only Google app that comes with such problems. Security experts have also commented on WebView and other Chrome Tabs on Android that too discloses the phones private information.

Any other Android apps running on Chrome to render web content will also be susceptible to the flaw.

What this Flaw on the Android Version of Chrome means for you? 

With the Android version of Chrome be susceptible to leaks, it means that no Android device is really safe. But what all this translates for you is that the information so obtained through the flaw can be used to track users and also fingerprint devices.

Besides this users phones vulnerabilities can also be determined and then used to get further information form the phone. This is not even the main part of the issue here. Experts say that the flaw pertaining to the Android version of Chrome was discovered back in 2015.

What Google did About it? 

As experts submitted the initial report pertaining to the bug back in 2015, Google gave a partial fix only in October 2018 for version 70. The fix is supposed to hide the firmware information and retain the hardware model identifier.

All versions of the app seem to be affected and users are encouraged to update to the latest version.
As for WebView users, this fix is not applicable and app developers should manually override the user agent configuration in their respective apps.

 

Fake apps on the Google Play Store: 

Recently fake apps were discovered on the Google Play Store. These apps have reportedly been downloaded tens and thousands of times. These apps were found on the Google Play Store and hid themselves as PDF readers, scanners and converters.

The apps themselves seem to be genuine but don’t offer the functionality that they were intended for. These apps are meant to increase the download count for other related apps and also to improve their ratings.

Essential Guide to Google Pixel 3

The Google Pixel 3 has a lot to offer but are you using it to its full potential? Maybe not? Then here are a few tips and tricks that are sure to improve your Pixel 3 experience. Not only that, you will be able to get more done in a short amount of time with these new tricks.

But before looking at what the Pixel 3 really has in store for you, you need to first ensure that your phone is trick- ready. By that I mean that you need to enable developer mode to get the most out of these tricks. You can do this by going to settings and then scrolling right to the bottom of the screen and tapping “about phone”. From there, go on to tap rapidly the “build number” to enable developer mode.

Accessing Notification Shade on the Pixel 3: 

This may not be a new feature on the Pixel 3 but has to be definitely enabled for you to quick access all your notifications from any screen.

You can enable this feature by going into the settings app and enabling it. Once done you’ll have to swipe down twice, while on any screen, to access all your notifications.

Get rid of the Notch on Pixel 3: 

There are ways to get rid of the notch which can be an eye sore for some. The notch on the Pixel is not really worth it as it does not do much and has no tech packed into it. But point to note, no matter what method you adopt you won’t be able to get the display portion on either side of the notch to work.

Besides going into settings and disabling the notch you can even download the Nacho Notch app from the app store to disable it.

Quick Launch Camera: 

You can get to the camera app by simply double clicking the sleep/wake button, when your Pixel 3 is awake or locked. This also allows you save space on your home screen by not needing to have the camera app there. Again you can enable this feature from the settings app by going into system and then gestures.

Another one in the Camera App: 

This feature allows you to switch between front facing and rear cameras by a simple gesture. To enable it all you have to do is go to System in the settings app and then to gestures and enable “Flip camera”.

Getting Daily Wallpapers on the Pixel 3: 

You can get daily wallpapers on Google Pixel 3. Android offers a lot of options when it comes to wallpapers, even more than what Apple do. You can get wall papers from third party launchers too. It is also possible to get wallpapers on the Google launcher as well, but with maybe a few more steps.

Enabling Dark Mode on Google Pixel 3: 

It took the people up at Google a while to get the new Dark mode to our phones, but in the end they came through. So now, in order to protect your eyes from the whiteness of the menu, especially during night, you can enable dark mode by again going into settings.

Terahertz Laser for Sensing and Imaging Outperforms Its Predecessors

Terahertz Laser is a high powered laser developed by Massachusetts Institute of Technology for chemical sensing and imaging. The Terahertz laser designed by the researchers of MIT, has three goals which includes high constant power, tight beam pattern and broad electric frequency tuning.

Terahertz Laser to be used by NASA on its 2021 mission to study our Galaxy’s origin

NASA has chosen the Terahertz laser for its 2021 mission to study more about our galaxy’s origin. With the help of a high altitude, balloon based telescope carrying photonic wire lasers, they will detect emission of gases like oxygen, nitrogen and carbon from the interstellar medium, which is the material between the galaxy’s star systems.

The Terahertz laser could also be used for skin and breast cancer imaging, detection of drugs and explosives and many other applications.

The design of the Terahertz Laser

The design of the Terahertz laser is unique which uses pairs of efficient wire lasers and sync their oscillations. On combining the output of the pairs there will be a single, high power beam with minimum beam divergence, which is the angle the beam moves away from its focus over distance. The individual paired lasers can be fine-tuned to obtain improvements in resolution and fidelity in measurements. All these give rise to less noise and higher resolution in order to achieve more cost effective and reliable chemical detection and medical imaging.

In the past, people have made a laser with high beam quality or with high continuous wave power or have done frequency tuning in lasers. But all the designs have one of the factors lacking. Ali Khalatpour, a graduate student in electrical engineering and computer science, who is also the author on the paper describing the Terahertz laser in Nature Photonics says that this is the first time where all three metrics are present in the chip-based Terahertz laser.

NASA has chosen the Terahertz laser for its 2021 mission

NASA will be using the Terahertz laser for its 2021 mission to detect gas emissions from the interstellar medium. By procuring data over a few months, they will get insight into the birth of the star and evolution. They will get more knowledge of the Milky Way and the Large Magellanic Cloud Galaxies which are close by.

NASA selected a new semiconductor based terahertz laser which is suitable for spectroscopic measurement of oxygen concentrations in terahertz radiation. It is a band of electromagnetic spectrum between microwaves and visible light.

Achieving three metrics in chip-based terahertz lasers

Researchers had developed new types of quantum cascade lasers known as photonic wire lasers. These were bidirectional and hence less powerful. This issue was sorted out by placing mirrors within the laser’s body. Since the terahertz radiation is too long, and the terahertz laser is small, it was difficult to fix it within the laser so much so most of the light travels outside the laser’s body. In the laser that NASA selected they developed a design to control how the electromagnetic wave travels along the laser and emit in one direction. They were able to obtain high efficiency and beam quality, but it did not allow for frequency tuning.

To overcome this, the researchers applied the concept of pi-bonding to the lasers, enabling close connections between the wire lasers. This coupling allowed phase locking of two or more wire lasers.
To obtain frequency tuning, they used tiny knobs to alter the current of each wire laser, which changes the refractive index. This change in refractive index together with coupled lasers, gives rise to a continuous frequency shift to the pair’s center frequency.

The researchers are building a system with a high dynamic range of more than 110 decibels which can be used for many applications including skin cancer imaging. Since skin cancer cells absorb terahertz waves more strongly than healthy cells, the terahertz lasers will be able to detect them.



With terahertz lasers having the three performance metrics, they can improve imaging capabilities and can be used in other applications.
