How to get my video file smaller with Leawo Video Converter?

Leawo Video Converter is a suitable tool to convert between all kinds of videos while it can help you adjust the videos to a desired size, say smaller file for space saving. It involves the knowledge on codec settings, a set of essential parameters for the task. It is easy to learn after all and here is a step by step guide on how to reduce the size of your video file with Leawo Video Converter.

Step 1, load the videos into Leawo Video Converter for processing. It accepts more than a score of popular video formats, so there is no worry for incompatibility.

Step 2, select a profile for the file you selected. More than 100 profiles, with reference to common video formats and particular terminal formats, are in crisp order. You may judge on the file extension and the description for one that matches your need.

Step 3, assuming you have assigned a 3GP profile, then click “Settings” to open codec settings panel. There is a full list of codec settings, dividing into two parts, for you to make distinct differences.

Video Codec: it is to determine which arithmetic to use in encoding the video. If you have ever uploaded videos to YouTube, you should be acquainted with YouTube’s recommendations on uploaded video format, which are H.264, MPEG-2 and MPEG-4. Leawo Video Converter has many codec plugins to cover most picky demands.

Quality: it specifies how much the video quality is to preserve after conversion. High quality usually brings good details on screen with the only holdback of large file size. It is recommended for video backup or broadcasting. When you want to view the video on small screen or memory-tight terminals, low quality is the best choice.

Bit Rate: it describes the bits per second in the video stream, reflects the video quality and video size in number form.

Video Size: namely the actual resolution of the video display in full size.

Frame Rate: it gives the idea of the frames per second in the video stream. A smooth video usually adapts a frame rate higher than 24. If the video contains mostly intense shots, a higher frame rate is required. Otherwise, you can lower the frame rate and reduce redundant frames in a slow motion video.

Aspect Ratio: it affects the display style on your player. 4:3 is preferred aspect ratio for TV or standard CRT screen, while 16:9 is often favored by wide screen LCD screen.

Audio Codec: same to video codec, except it is dedicated to audio. A moderate choice is MP3 for its widespread popularity around cyberspace. AAC features a better performance in a smaller file size, preferred on memory-tight cell phones or PMPs. AMR is the best choice for carrying voice because of its slim body, but not suitable for music enjoyment.

Quality: same as video.

Bit Rate: same as video. Usually a video file would contain both video stream and audio stream, so the total bit rate will be the sum of video bit rate and audio bit rate.

Sample Rate: a factor that determines the details of audio. It goes the same as Frame Rate.

Channels: an audio stream can be single channel (mono), double channel (stereo) or even 5.1 channel (surrounding). It can be easily determined by how many sub sound boxes you have in your audio system.

There are some important rules to follow before you start the conversion.

1. do not apply a profile with parameters higher than the present of your video file. It simply doesn’t improve the quality but results in unnecessarily larger file.

2. the higher is not always the better. For example, you might experience frame drop while watching H.264 videos on your PMP but not the case with MPEG-4. The reason is that your PMP is not strong enough in decoding advanced but complicated format like H.264, so you have to make do with MPEG-4 or MPEG-2.

3. better not raise too high on frame rate, sample rate and bit rate. Blind pursuit for higher figure does not guarantee a better result, but increase the possibility of low efficiency, such as redundant frames and bloated file size.

After absorbing quite an amount of knowledge on codec settings, you must eager to practice for the very first time on your own. Leawo Video Converter provides comfortable experience during conversion, such as batch converting and after done actions, brings the task easier and faster to its goal.

Spotlight on 2009 TED Prize: Protect Our Oceans by Sylvia Earle

The inspiring 2009 TED Prize has honored three outstanding researchers for their fruits that can cast mortal impact on the world of the day and even change the future of mankind. Sylvia Earle is one of them. Let’s get in touch with the thought of the great mind.

As an ocean researcher, Sylvia Earle has long been assiduous in her work to find the unseen facts of the ocean. And they turn into the stimulating images she shared with us on TED stage. That is a marine world far beyond our life but life there is flourishing.

These are the good facet of the ocean. Sylvia also mentioned the opposite. That is, our ocean is in danger. However, it is not caused by the ocean itself, but by us.

As Sylvia Earle mentioned, in the past 100 years, we kept ravaging the ocean by dumping and pouring large amount of waste and pollution into it, but we rather falsely think that the ocean is so immense that it could tolerate whatever we do to it. This false point of view has resulted in the facts Sylvia uncovered: we have eaten 90% of the big fish in the ocean and destroyed half of the coral reefs. The oxygen in large areas of the Pacific is depleted mysteriously. More facts continue on the list. Sylvia Earle’s research does remind us of overwhelming fishing activities, merciless wildlife killing and reckless forest logging. We can feel the weight in her words.

In her speech, Sylvia Earle compared our earth to the life support system on a sub boat or on a spaceship. When living in a lifeless space, people will treasure life support system or they will die without it. And the earth is our life support system in the universe. There is no reason we should harm our life support system and ask for the punishment. Though it is illogical, the wrong path has been taken. It is now or never to turn on the right way. Environmental conservation and campaigns are on the way to thrive, but they are still too weak and scattered to counteract the damage. What we need is a global mobilization. And this is the aspiring wish of the respected lady at the end of her talk.

I wish you would use all means at your disposal — films, expeditions, the web, new submarines — a campaign to ignite public support for a global network of marine protected areas, hope spots large enough to save and restore the ocean, the blue heart of the planet. – Sylvia Earle

Nothing will match the convergent strength of the entire mankind, if we decide to do something great together.
