MP4Cam2AVI

MP4Cam2AVI is a software which enables you to convert video files of the MP4, MOV, AVI and 3GP format to the AVI extension.

Since the tool doesn't need installation, it is portable. You are free to store it on an external device and run it on any computer. More importantly, your Windows registry keys will be intact.

The interface of the program is plain. You can use the treeview or the file browser to locate video files on your hard drive (the "drag and drop" method is not supported but batch processing is).

You can preview the source video (with the possibility of opening it in the default media player by double-clicking it) and select the preview mode.

But you can also mark the starting and ending point (so, MP4Cam2AVI is also a video splitter), as well as select the audio format (e.g. Lame MP3 high quality, no recompression), AVI size limit, thread priority, output destination and name.

You can set the tool to prompt before overwriting, select the action (convert and join, or batch convert), switch to timeline mode and save it, edit the target AVI in VirtualDub, configure advanced settings (e.g. resample, lowpass filter, resize), and more.

MP4Cam2AVI takes up a moderate amount of system resources and includes a well-drawn help file. We weren't able to access the conversion log (an error popped up), the tool requires you to separately install some third-party components that it needs to fully function and it cannot merge files of different frame sizes without recompression.

MP4Cam2AVI is a good program for converting files to the AVI format. It simply needs some debugging and improvements concerning functionality. Otherwise, it can be used by individuals of any experience level.
