MilestoneMP4 format conversion tools and tutorials in Ubuntu

I just changed milestone a few days ago and wanted to see my own little rock playing capabilities. However, Android only supports videos in MP4 and 3GP formats by default, therefore, you have to convert the video on your machine. However, since your system is Ubuntu, most of the conversion software found on the internet is windows and cannot be directly used. Later, I found an open-source free video Conversion Tool HandBrake on the Internet and installed it as follows: & gt; sudoapt-add-repositoryppa: stebbi

I just changed milestone a few days ago and wanted to see my own little rock playing capabilities. However, Android only supports videos in MP4 and 3GP formats by default, therefore, you have to convert the video on your machine. However, since your system is Ubuntu, most of the conversion software found on the internet is windows and cannot be directly used. Later, I found an open-source free video Conversion Tool HandBrake on the Internet and installed it as follows:

> Sudo apt-add-repository ppa: stebbins/handbrake-snapshots

> Sudo apt-get update

> Sudo apt-get install handbrake-cli handbrake-gtk

After the installation is complete, you can find handbrake in the Application> audio and video

Open handbrake, expand Legacy in Presets in the right window, select iPod Legacy, and set Format in Destination to MP4, do not select the following iPod 5G Support/Web optimized/Large file (> 4 GB) hooks, switch the following tags to the Video tag, and set Bitrate (kbps ): the value is 1000, and the value of Framerate is 29.97 (NTSC Video) (this must be higher, otherwise frames will be lost after the press is finished). Switch to the Audio tag and set Mix to Stereo, these steps have been completed. Finally, you can set the size of the video after conversion. In Picture Settings in the upper right corner, enable Picture Settings and select Optimal for source, which is the same as the size of the original file, if the size of the Source Video exceeds the maximum resolution of ms (480 × 854), you need to set the width and hei Ght is the appropriate value. Select Keep Aspect, which will maintain year-on-year scaling. www.linuxidc.com prevents deformation after image conversion. The basic settings have been completed. To facilitate the next conversion, you can click the Save icon in the lower-right corner of the main interface and save another configuration name. You can directly use this configuration next time to convert the video.
