HD Player Helper

HD Player Helper is a small-sized and portable application that enables users to transcode videos. It offers support for the MKV, AVI, FLV, MP4, MOV, M4V, VOB and TS formats.
Since installation is not a requirement, you can drop the program files to any directory in the hard drive and just click the executable to run.
It is also possible to save HD Player Helper to a USB flash disk or similar storage unit, to be able to run it on any computer with minimum effort and no previous installers.
What's more, the Windows registry does not get updated with new entries, and no additional files are created on the disk without the user's consent.
The interface is made from a regular window with a standard structure. It is not visually appealing but quite easy to get around. Files can be selected for transcoding using the file browser only, since the drag-and-drop method is not supported.
Batch processing is not possible, meaning that you can work with only one item at a time. So, all you have to do is select an output audio codec from the list (Vorbis, FLAC, AAC, MP2) along with a saving directory, and proceed with the transcoding operation by clicking a button. Once the task is done, HD Player Helper offers to open the target location. There are no other notable options provided by this utility.
HD Player Helper carries out tasks swiftly while using low CPU and memory, so it does not hog system resources. We have not experienced any type of issues in our testing, as the software app did not hang, crash or display errors.
In conclusion, HD Player Helper delivers a straightforward solution to transcoding video files, in order to prepare them for HD Player or HD Player Pro playback.
