 The OP is reporting that the whole file is conveyed when trimming out at 5
 seconds. Streamcopying will, at most, add a few frames in the video
 stream, when trimming the out point. Also, the output is fine when
 trimming is set via output options. In both cases, the video is being
 streamcopied.

 So, there is a more subtle anomaly being seen here.

 To the OP, please re-upload the 2nd file, at least.
