[Beginner’s Guide] What is Transcoding? How to Transcode Videos?

Video transcoding or video encoding is the digital-to-digital conversion of one encoding to another. The transcoding process usually involves at least one of the following conversions - codec conversion (e.g. H.264 to H.265), resolution conversion (e.g. 1080P to 4K), size conversion (compression) and bitrate conversion. The opposite of video transcoding is remuxing, which means changing the video container only.

Video transcoding is often required to improve video playback performance and quality on different devices or platforms. For example, if you want to fix an unsupported video format on TV, you can transcode the video to a TV-compatible format. Fortunately, video transcoding is easy as long as you use the right video transcoder. In the next part, you will learn an easy way to transcode videos to any format you like.

Step 2. Make Transcoding Preparations

>> To Transcode Video Format: Click on the format image on the right side of the workspace to open the format page. There you will see all the available formats and preset specs, including MP4, MKV, AVI, MP3, WAV, H264, H265, VP9, DVIX, YouTube, Vimeo, Facebook, Yahoo, iPhone, Xbox, Fire TV, Android TV, Apple TV, and so on. Choose your preferred output format.

>> To Transcode Video Size/Quality: Below the output format where the “Quick setting” is, drag the slider to quickly upscale/downscale or enlarge/downsize the video.

>> To Transcode Other Video Parameters: Open the “Parameter Settings” under the format image. There you will see all the available options, such as encoder, resolution, bitrate, frame rate, aspect ratio, etc. Tweak these settings in any way you like.

Step 3. Start Transcoding

When you are ready, hit “Run” to start the transcoding process.

Video transcoding is needed more often than ever in today’s multimedia era, especially with the streaming industry on a tear. For example, when your device does not support a 4K resolution, but you want to play a 4K movie on that device from your Plex server, the Plex server will have to downscale the video resolution to your device-compatible resolution to secure a smooth video playback on your device. And that resolution-downscaling process is transcoding. Or a more common case is when you are doing live streaming, the raw data captured by the camera will be transcoded into various renditions so the end-user can watch the streaming content on different devices and at different quality. Such transcoding is also called cloud video encoding that is automatically done without your interference.

There are times you also need to transcode videos yourself. The common circumstances are:

1. The current video file is not compatible with your device;

If a video can be successfully played on other people’s devices but not on yours, it is largely because it is in the wrong video format that is not supported by your device. Take the MOV files, the .mov videos can be smoothly played on Apple products but not natively on Android phones. Either you can get a MOV player or transcode it to Android-friendly formats to make it compatible with your device.

2. The current video file is too large for your device;

This is very true in transcoding footage, a raw and unedited material recorded by the camera. It's impractical to just share the footage with others because of its big size and the unsupported raw format. Luckily, you can transcode footage in many video editing software like Premiere Pro, DaVinci Resolve, Camtasia, etc.

Also, when you have a small device memory, transcoding the video to a smaller size file is recommended.

3. The current video file is expected to upload to online platforms (e.g. YouTube, Vimeo, Instagram, etc.)

This is one of the major reasons why transcoding videos are so important. The online video-sharing platforms have their particular rules for uploading videos in terms of size, resolution, format, length, and so forth. And you have to transcode your videos to match their proper specs to guarantee a successful or smooth upload.
