Конвертер mp4 to avi linux

use ffmpeg to transform mp4 to same high-quality avi file?

I would like to use ffmpeg to transform an mp4 video file into avi but with the same quality, even if it takes up more space. If I simply do:

ffmpeg -i file.mp4 file.mp4.avi 

The resulting avi file is very low-quality and pixelated. How can I do this transformation while keeping the video and audio quality?

You can use -sameq switch, which will put same video codec (assuming H264) in AVI container. If your player does not support H264 in AVI, then you need to transcode best possible video format (H264) to some mediocre format, which is no good. Then you assign higher video bitrate XVID (let’s say 2000 Kb/s). Audio doesn’t matter that much IMHO, but better to convert to MP3 then AC3

ffmpeg -i filename.mp4 -vcodec copy -acodec copy filename.avi 

Be aware that embedding AVC streams in AVI containers requires a hack that is supported by many community-driven video players (e. g. VLC, MPlayer, anything FFmpeg/Libav or GStreamer, Media Player Classic) but not by many commercial players (e. g. Windows Media Player and QuickTime/iTunes don’t support it).

Does it mean that doing that command i am reducing chances of playing that file on some devices like older SMART TVs?

You always lose a little quality whenever you transcode from one codec to another, video or audio, but perhaps you can avoid it if you only want to change from MP4 container type to an AVI container. codec:copy may be helpful if you don’t have a reason to transcode (and it should be faster).

If you must transcode because you need to use a particular video codec I hope you can use zetah’s suggestion above in his comment and use the -sameq switch. Alternatively, you may want to use the qscale option to set the quality manually. The lower the number the better the quality, but the more space your file will take.

The last time I transcoded video I used qscale=8.0 , but I’d suggest that you experiment to find the optimum to match the quality of your input.

Marty Jay helpfully mentions that sameq means same quantizer as in the input, which may not result in the same quality. The article he quotes mentions using multi-pass conversion, which is a good way to achieve better compression without sacrificing quality.

How to Convert an MP4 to Avi in Ubuntu (and Watch on a DVD Player)

Are you an avid downloader of videos and movies (legally) online? Do you prefer to watch movies on your DVD player? It turns out, many people prefer to experience a good movie while relaxing on a sofa and watching it on a television screen. Unfortunately, if you have an older DVD player, you won’t be able to play MP4 videos directly from a USB or other external media.

The reason for this is that the standard AAC audio codec is incompatible with DVD players due to license restrictions. On the other hand, the MP3 audio codec is universally accepted. The open source version of DivX video codec is Xvid (essentially DivX spelled backwards) and is accepted by many DVD players including older ones displaying the DivX logo.

For Windows and Mac users, there are numerous applications to convert MP4 files and other formats into AVI format which older DVD players can play back. The story is different on Linux. There aren’t as many solutions and the process to actually get it done is sometimes too technical.

This MakeTechEasier solution is actually quite easy. Enter WinFF, a free open source video converter published under the GNU public license v3. It is cross platform and can be used on both Linux and Windows and supports several languages. Below is a tutorial on how to install and use WinFF in Ubuntu (Trusty Tahr).

Downloading and Installing WinFF

WinFF is available in the Ubuntu Software Center. Just launch your software center and type “WinFF” in the search bar. Take note that the application has certain dependencies that must be installed to make it work. One of thes is the libavcodec package, which can be obtained by installing the unstripped version of libavcodec-extra as suggested by WinFF during installation.

If you are running an old version of Ubuntu, you will have to install the WinFF Personal Package Archive (PPA) provided by Launchpad. Open a terminal window using “Ctrl + Alt + T” and type:

sudo add-apt-repository ppa:paul-climbing/ppa

After that, update your system:
