My MP4Box GUI is a Graphical User Interface for the well-known command line tool mp4box. My MP4Box GUI, like mp4box, is freeware. MP4Box is an MP4 muxer. It can import MPEG-4 video (H.264 or ASP, encoded for example with x264, DivX, Xvid, 3ivx or FFmpeg) and audio streams into the MP4 container. The end result is ISO compliant MP4 streams. It can also produce MPEG-4 Timed Text streams by importing subtitles formats such as srt. It can also split MP4 files into sections, which can be useful when transferring files to portable media players. Join and Split.

Jan 26, 2018 Version: OS: Windows 7 64-bit Ease of use: 9/10 Functionality: 9/10 Value for money: 9/10 Overall: 9/10

Thanks for posting an idea, pintcat :)

I have VC++ 2005, 2008 and 2013 installed.

The error that happens is "The application failed to initialized properly (0xC0000135)". This error occurs 90% of the time due to a wrong or no .NET installation (per web search).

I've purposely not had dotNOT (dotNET) installed on the subject machine due to the morass of problems that different dotNET versions caused in the past. I'll be ending use of XP on it in the near future (and running Linux!). So i'm reluctant to install dotNET for 1 app.

BTW, it's great that free software like this is available but documenting running requirements is a basic tenent that prevents problems like this. I've seen people not explicitly state requirements for software so many times, across multiple platforms and multiple license schemes. This software is no longer developed, and free, and so doesn't apply but... i wish there was a documentation police agency that would go around fining people for not stating software requirements! ;) It isn't hard AT ALL.

Nov 18, 2017 Version: OS: WinXP Ease of use: 5/10 Functionality: 1/10 Value for money: 5/10 Overall: 2/10

@TRXRT: It's running fine on my WinXP SP3 (32bit). Do you have all the suitable runtimes installed? I think I'm using VisualC++ 2010 (x86).

Nov 17, 2017 Version: OS: WinXP Ease of use: 8/10 Functionality: 8/10 Value for money: 1/10 Overall: 8/10

This program would not run on Windows XP SP3. Seemed to be a typical C/Library error, "This program terminated blah blah...[0xAddress]" Haven't tried on a windows7 laptop.

(Yes, laugh all you want, but there are still isolated boxes with Windows XtraProfit still on them! And mine's been stable for years. I wouldn't have even tried it if there was OS version info in the requirements section.)

To try to be fair to your scoring system, I put 5/10 in the neutral metrics, accurate score of 1/10 in functionality, and combined best-accurate score of 2/10. I certainly don't fail to appreciate the effort put into free software though!
