What are the factors that affect video quality? Part 2
The “image quality” of a video is actually a very complicated topic.
The last and most problematic is the video format.
There are endless video formats, and we are also dazzled in the process of practical application. LOL
Which AVI WMV MKV MXF MOV M4V MP4 RMVB MPG FLV
It’s really stunning, isn’t it?
Next, let’s talk about ranking. AVI is similar to WAV in audio files. It has the most volume, but is usually the original material. The biggest advantage of AVI is that it can be streamed. Basically you can use NLE to edit in all office conditions Minus it is very inconvenient to wear
WMV is the Windows Media Video compression specification. MOV are the two QuickTime formats. These two formats are the most widely used HD encoding formats under current technical conditions.
MP4 is mpeg4 . We should all be very familiar with mpeg2 . Supported by excellent encoders, MP4 is also a format that can be frequently used in high-definition environments. Don’t underestimate mp4 because of the inherent concept. The uses of mp4 are many, very wide and very convenient. m4v is an mp4 file in some specific encoder environments, and m2v corresponds to mpeg2
MXF MKV is the package format. To put it bluntly, it’s the box brand. The decoders used in the box can be various and support a wide range of use and high efficiency. In general, finished products that do not require reprocessing can choose these two formats. Basically, this format is selected. It is equivalent to “packaged, ready to receive”. The degree of freedom is very large, and the encoder can be the common DivX, XviD, 3IVX, or even Real, Quicktime, WMV, etc.
RMVB, as the name suggests, the RealVideo format has a high compression rate and the video quality is poor. It is generally used for what you know. Now it is rarely used.
FLV is basically the worst format. .
