how to convert hundreds of mkv videos to mp4

[Lazare Londaridze]

Hello. I have over 400 MKV videos which i want to convert to MP4 , which program should I use ? I need a loss less converter which can convert many files at the same time.
Please help

I have a PowerShell script that converts videos to MP4 for playing on Chromecast. If your MKV has certain A/V formats, it will simply remux to MP4 without "loss." The script could be adjusted to remux everything without respect to the current A/V formats.

I'm not competent at stuff like that, is there any program which can do the job easily ? ( select multiple videos and convert them )

Simple script and ffmpeg should be able to deal with this however please notice fact that mp4 is very limited and support less than mkv - as such simple copy may be not possible and some transcoding will be necessary.

@setlocal
@if not exist %CD%\out (mkdir %CD%\out)
@FOR %%a IN (*.mkv ) DO (@ffmpeg.exe -y -hide_banner -stats -loglevel 32 -i "%%a" -sn -copy -movflags faststart -f mp4 "%CD%\out\%%~na.mp4")

Don't know that much but thanks anyway.

mkv2mp4

Will try thank thanks

mkv2mp4 is really nice, but the videos all have to be originally in H264, or they don't mux properly. you basically get sync issues. I really like the program though. For the ones that don't work, you may want to use mkvmerge GUI to find out what they were originally created as. What is the reason you're trying to convert to MP4? That might be the better question.

Notepad
copy text (ctrl+c)
paste text in notepad (ctrl+v)
save file with name you like and extension cmd or bat
download ffmpeg (from zearanoe static build - select based on your system - 32 or 64 bit)
unpack ffmpeg archive
copy ffmpeg exe to folder where you have your mkv files
copy file created with notepad (that one with extension bat or cmd)
to flder with mkv files
run script (click on file same as any other application)
conversion is started, new mp4 files will be created in folder "out"
