When transcoding does not change the aspect ratio in the video?
The problem is that there is a video file:

now the aspect ratio of 720:544 ~= 4:3 is also quite common.
To preserve the quality of the video, it is best not to re-encode it. You can repackage to MKV if required - (?) - but leave the video as it is. If we transcode the video, then into the codec h264
and the sound into AAC
- this is the de facto standard for video on the web.
You don't really need to increase the size. If the requirement is to fit into 16:9, you can add black (or even pink) stripes on the sides or enclose a blurry enlarged copy of the video, as is done for vertical mobile videos, fitting them into a horizontal format. Leave the height at 544, and increase the width to 720 / 9 * 16 ~= 968
(must be divisible by 4 - codec requirement). Those. do 968x544
For all these tasks I would use ffmpegfrom the command line. It is available for all platforms, free, a lot of features, standard solutions can be googled. Under the hood, "Any video converter" also probably has ffmpeg.
Well, while you are experimenting, run a short fragment of the video, not all 43 minutes, but 10 seconds.
MKV is a container! How to zip rar
Download mkvtoolnix, upload the file, choose a save path different from the location of the original file
Press execute
On the output you will get your video file without converting to mkv
MKV is not a format, but a container. In your case, the XviD Codec, you will recode it.
If you want to scale (enlarge horizontally), which is often done by "oatmeal foreheads" on TV SPAS, then you need to use "resize". ..
So transcode XviD to H264 codec into MKV container
