Media Converter

v3.0.2 is the latest version. It's Universal, for both Intel x86 and ARM (Apple Silicon). It was released February 25, 2023. From the ReadMe: "* Added workaround for accessibility issue in macOS Ventura. * Fixed localisation issues."

V3.0.1 (18) is now out.

Finally, just what I needed! My problem is weak audio within videos that need amplification. - Handbrake can do it, but can't do pass-through video, making it time consuming and larger files. - MKV2MP4 has pass-through, but somehow the audio amplification doesn't work, even when I tried re-encoding the sound. MediaConverter stands out by allowing me to create a new encoding profile that allows for video pass through, and custom ffmpeg commands. A quick google helped me amplify the audio via the custom commands and I was done. One minor lacking feature... a watch folder to process videos automatically.

I'm amazed that this app hasn't been updated since 2011 and still beats its competitors in some points!
I've tested quite everything available on the market, free and paid ones, there are surely a lot of apps that can do precisely complex conversions with the exact settings you want, but I was searching for a simple and fast way to set down the resolutions of films to watch them on my Dell Mini 9 (which is not the state of the art of modern computing, but very handy with its small size ;-) ): normally sized films are usually played with a lot of stuttering, so I choose the "iPod/iPhone" setting on Media Converter, the file gets bigger (a 850 Mb film becomes 1.3 Gb) but it's played fluently on my DM9!
Note that the conversion is done with ffmpeg at 64 bits (check it in Activity Monitor).
I've just tried to substitute the ffmpeg file inside the package with the latest available but it crashes, so I'll stick with Media Converter as it is... :-)

P.S. : I'm on OS 10.9.5

I just updated to Mountain Lion (10.8.2), and now although Media Converter v1.2 rewraps the video, there is no audio?

I use this all the time with my AVCHD .MTS video files, and it works great with no quality loss re-wraping to .MOV files.

Though this is free the quality is very poor. Also struggles with aspect ratios. Very simple but Handbrake seems to be much better.

This is a great app with one exception every time put in a 4:3 video no matter what I change the settings too it treats it as a 16:9 video.

This is what I've been waiting for ever since the demise of VideoHub. And this one is free. And simple ... but powerful. And extensible. The simple interface belies its actual power. Very good potential. Excellent for a version ONE.

Tried a couple of mkv files. Not one worked. This version is useless to me.

Uses a old ffmpeg from another app. The dev doesn't seem to know how to compile a FFmpeg himself. Anyway, it is simple to use but lacks many codecs and options. Good is free though.

awesome! a free batching GUI front end to ffmpeg. I love it so far. Preset editing should able to be accessed from the main window somehow (at bottom of preset pop-up menu maybe?) and you should be able to duplicate presets. But other than that, great. I like that you can specify command line options by hand or use the GUI - whichever you prefer. I just made a couple preset files for re-wrapping AVCHD (.MTS files) from a video camera to an h.264 quicktime movie that can be played/transcoded for editing with quicktime based software: http://arvidtp.net/browse.php?dir=/sw/Media%20Converter%20Presets
