FragMend

Steam's Game Recording feature saves your gameplay as fragmented MPEG-DASH files - dozens of tiny chunks split across folders, with no easy way to get a normal video out. FragMend fixes that.

Select your recordings and it automatically:

• Auto-detects your Steam install, account, and the real recording folder (even on another drive).

• Rebuilds real sessions

• Groups the scattered fragments back into one video per play session, per game, using Steam's own timeline data.
• Exports clean MP4s
• Lossless by default (based on original recording quality set in Steam), with an optional H.265 re-encode for maximum compatibility or H.265 for saving disk space without compromising quality.

• Names them sensibly
• Output is organized by game and date, ready to edit, upload, or archive.

Everything runs locally.

Your recordings never leave your PC — no uploads, no accounts, no cloud. ffmpeg is bundled, so there's nothing else to install.

Just launch FragMend, let it scan, pick the sessions you want, and Convert.
