Trimming .tp files (MPEG transport stream files) without re-encoding is a common task for video editors and enthusiasts who want to save time while maintaining the original quality of their footage. In this article, we will explore how to efficiently trim these files, understand the importance of not re-encoding, and provide practical examples and resources to help you achieve the best results.
