ReJig

ReJig is a small and portable MPEG-2 transcoding utility that uses compressed domain transcoding. It can recompress MPEG2 to MPEG2, as well as author DVD clips and back up DVD movies.

Since installation is not a requirement, you can just drop the executable file on any location on the hard drive and run it directly.

Otherwise, you can copy the app to a USB flash drive or similar storage unit, and run it on any computer without prior installments. More importantly, the Windows Registry does not receive new entries and no files are found on the hard disk after removing the tool.

The interface of the app is based on a small frame with a well-defined layout, where you can back up DVDs from discs, ISO images or folders from the hard drive.

By switching to file mode, you can import MPEG-2 or CCEData files into the recopressing job list, as long as they have the VOB, TXT or TS format. It is possible to specify the output filename. directory (M2v format) and recompression method (one or two passes). The IFO recompression mode allows you to correct AC3 delay, to convert subtitles files to the IFOEdit Sup format, and to enable automatic authoring mode.

From the Settings area you can select the ReQuant engine mode (old or new), set the drop frame flag (GOP control) and enable the option to keep files that were created during the backup procedure.

ReJig needs a pretty low quantity of CPU and system memory, so it does not interfere with the runtime of other active processes. We have not encountered any difficulties throughout our testing, since the tool did not hang, crash or pop up error dialogs. Although it has not been updated for a pretty long time, ReJig should be able to please power users.
