These devices had tiny LCD screens with limited color palettes and processing power. Playing a standard 720p video on them is impossible—not just because of the screen, but because the phone’s ARM processor lacks the memory bandwidth to decode large frames.

The exclusivity is not a marketing gimmick—it is a warning and a promise. A warning that generic converters will fail you, and a promise that this one will produce a video your retro phone will actually love.

Always convert your video in 15-second test clips first. Nothing is worse than waiting 40 minutes for a full movie conversion, only to see a "Format Not Supported" error on a 2-inch LCD.
