mp4 to RMVB format is small and clear. RMVB is a new video format extended from the RM video format upgrade. Its advancement is that the RMVB video format breaks the average compression sampling method of the original RM format and rationally utilizes bit rate resources while ensuring the average compression ratio.

What format can be converted to mp4 that is small and clear?

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Videos are composed of audio streams and video streams. The size and definition of the video have a great relationship with the bit rate of the audio stream and the bit rate and resolution of the video. Let’s first analyze the situation of common video formats and then summarize. Let’s talk about 3GP first, which is mainly used for mobile phones. Most of the videos shot by mobile phones are in this format. The main reason is that the capacity is small and the picture is average. If you are viewing it on a larger screen or computer, it is not recommended to convert to this format.

RM and RMVB have good image quality and medium capacity. Real Video or Real Media is a file container developed by RealNetworks. It can usually only accommodate Real Video and Real Audio encoded media. This file has certain interactive functions, allowing scripts to be written to control playback. RM, especially the variable bitrate RMVB format, is very small and very popular with Internet downloaders. RMVB is a new video format extended from the RM video format upgrade. Its advancement is that the RMVB video format breaks the average compression sampling method of the original RM format and rationally utilizes bit rate resources while ensuring the average compression ratio. Rmvb is currently the most commonly used video format that occupies a relatively small space and has relatively good quality.

AVI is the abbreviation of Audio Video Interleaved. The picture quality is clear and generally larger. Developed by Microsoft, it is a format that interweaves video and audio for simultaneous playback. Generally, *.avi files are larger in size and have good picture quality. There are also compressed *.avi files, but since the compression standards are not uniform, compatibility issues may arise. WMV is a technical standard for real-time dissemination of multimedia on the Internet that is independent of encoding methods. Microsoft hopes to use it to replace technical standards such as QuickTime and file extensions such as WAV and AVI. The main advantages of WMV are: scalable media types, local or network playback, scalable media types, stream prioritization, multi-language support, scalability, etc.

MPEG1, MPEG2, MPEG4, the picture quality is very clear and the capacity is relatively large. MPEG is the abbreviation of Motion Picture Experts Group, which includes MPEG-1, MPEG-2 and MPEG-4 (note that there is no MPEG-3, the familiar MP3 is just MPEG Layeur 3). MPEG-1 is believed to be the one that everyone is most exposed to, because it is widely used in VCD production and some network applications for downloading video clips. It can be said that 99% of VCDs are compressed using the MPEG1 format. Using MPEG-1 The compression algorithm can compress a 120-minute movie to about 1.2 GB in size. MPEG-2 is used in DVD production (compression), and it also has considerable applications in some HDTV (high-definition television broadcasts) and some high-demand video editing and processing. Using the MPEG-2 compression algorithm to compress a 120-minute movie (not a video file) can be compressed to a size of 4 to 8 GB (of course, its image quality and other performance indicators are incomparable to MPEG-1 ). MPEG-4 is a new compression algorithm. The ASF format using this algorithm can compress a 120-minute long movie (not a video file) into a video stream of about 300M, which can be watched online.

MP4, the most commonly used video format, has generally better image quality and higher capacity than RMVB. MKV, TS, MKV is used for encapsulation, just like packaging, it is relatively large and the picture is very clear. TS is commonly used in HD and ultra-clear. Generally, the video capacity and resolution are very large. If you want the video to be small and clear, it is recommended to use the RMVB format, which can take both picture and size into consideration. If your mobile phone or mobile storage device has a large capacity, it is recommended to convert it to MP4 format.
