Merge video files using LosslessCut

Soon after that we came across the free and open source video editor LosslessCut. We were excited to discover that this free software can help us concatenate files in series in a much easier way. We can’t wait to share with anyone who face the same issue.

Drag video clips in the left pane to reorder them if needed. Then hit the Merge button above the list to get more options before you join them all together into one.
