Bạn đang xem: Encode video là gì
Video technology has undergone massive evolution in the past couple of decades. This growth has come simultaneously with the development of the internet.
While motion pictures—videos made of large collections of still photos—were fine in the age of VHS tapes and even DVDs, they made for excessively bulky files when videos became digital. It became difficult lớn upload và cốt truyện with more modern types of hardware.
Video encoding was brought lớn life as a solution to lớn aid in this technological transition.
Let’s break down đoạn Clip encoding for live sầu streaming và talk about the importance of each moving part.
In this guide, we’ll address:

There are seven common encoding challenges that broadcasters find themselves facing. Here are a few solutions that may help you navigate encoding roadblocks that you may encounter.
1. My viewers tend lớn have slow Internet connections.
Video files tkết thúc to be larger files, so they require fast mạng internet tốc độ with great bandwidth to display the video properly. When the Internet connection is slow, the video starts stuttering và often displays in very poor chất lượng.
With balkanpoliticalclub.net, you can use the analytics feature lớn determine where most of your viewers live sầu. Then, the software will match that information with average internet speeds khổng lồ get a sense of the average connection tốc độ of your customers.
You can mix your overall bit rate to lớn match their tải về tốc độ in order khổng lồ achieve a reliable playback. We recommkết thúc a short trial and error chạy thử to lớn determine which settings to lớn use. This will help you determine how low you can get the bit rate of a Clip while maintaining the appropriate quality.
To conduct the demo, you can start with a high frame width (say 1280px, which is 720p at the 16:9 aspect ratio) và a relatively low bit rate (around 512kbps). See how the đoạn phim looks when encoded with these settings. If you are not pleased with the image quality, try either lowering the frame width or increasing the bit rate.
Also, be sure to encode multiple versions of your Clip. Adaptive streaming will ensure viewers get the best quality they can stream smoothly.
2. I want khổng lồ save sầu bandwidth.
The more often your videos play & the higher their quality, the more bandwidth you will need. Every balkanpoliticalclub.net pricing plan comes with a particular bandwidth limit. You can use the same approach as in the previous question khổng lồ reduce bitrates to the lowest acceptable level. This will reduce your bandwidth consumption.

3. My encoded đoạn phim has a larger tệp tin size than the original one.
While encoding can’t increase quality, it always changes file kích cỡ. In other words, don’t worry too much about larger tệp tin sizes. Sometimes, this just means you’ve sầu been overly generous with your bitrate settings. Other times, it means you’ve sầu changed from one codec to another.
If you really need lớn reduce file size to lower bandwidth consumption or serve sầu users with slow internet connections, try reducing the bitrate.
4. After encoding, the audio is out of sync.
This could have sầu something khổng lồ vị with the frame rate of your đoạn Clip. Use a không lấy phí tool khổng lồ check the frame rate of your original file. If the frame rate of your Clip is unusual, you may discover the audio is out of sync after encoding.
In that case, we recommkết thúc you try the Two-pass Encoding feature. This can solve sầu many issues the encoder might have sầu interpreting frame rates.
If it’s not the frame rate and the audio continues to play up, you will need to lớn kiểm tra the relative length of the audio & đoạn Clip streams. You can use the same tool mentioned above khổng lồ get that information. In some cases, you may have sầu created source files with different lengths for their audio and video streams.
When this happens, the encoder doesn’t always succeed in precisely matching up the streams as they were before. Again, try two-pass encoding. However, if the problem persists, you may need khổng lồ ask your đoạn phim editor khổng lồ cut the original tệp tin.
5. My Clip is already encoded in a web-ready format
If your đoạn Clip is already an H.264 encoded MP4, you can turn off balkanpoliticalclub.net’s encoding by selecting “no encoding” in your ingest recipe. However, one thing you need khổng lồ keep in mind is the MOOV atom. MOOV atom is a bundle of metadata. Before saying no to this encoding solution, ensure the MOOV atom is positioned at the beginning of the file.
If this sounds complex, we recommover simply using balkanpoliticalclub.net’s built-in encoding to lớn re-encode your MP4 file. As long as you choose the same frame kích thước và bit rate as your original tệp tin, encoding the đoạn phim with balkanpoliticalclub.net will not have any noticeable impact on its chất lượng.
6. I don’t want my videos in an MP4 format
The balkanpoliticalclub.net hosting solution only encodes content lớn H.264 in an MP4 container. If you feel that you need your videos encoded in another format, have sầu a chat with our Support Engineers và we’ll see what we can do for you.
7. I uploaded a Clip và the quality is really poor
Generally, this means the frame kích cỡ & bit rate of the target video are much lower than the original video clip. To get the maximum quality of your videos, be sure to use the “Original” profile in your ingest recipe in addition khổng lồ any lower qualities you have sầu selected.
This will match the source file’s frame kích cỡ và ensure you have sầu a high-unique version of your đoạn phim available.
