third setting means for setting an out-point, in response to a request to finish playback of the video data, at a position in the video data that is being played when the request is made; and

generating means for generating other video data from the video data of a section between the reset in-point and the out-point.

2. The editing apparatus according to claim 1 , wherein the playback of the video data by the playback means includes variable speed playback and pausing of the playback.

3. The editing apparatus according to claim 1 , wherein the temporary in-point is updated as the video data is played in reverse.

4. An editing method comprising the steps of:

switching to a preview playback mode;

forward playing the video data for preview playback of the video data;

setting a temporary out-point and a temporary in-point, in response to a request for reverse playback of video data, at a position on the video data when the request was made;

generating a temporary clip of the video data of a section between the temporary out-point and the temporary in-point;

reverse-playing, in response to the request for reverse playback, the video data, wherein the temporary in-point of the temporary clip is updated as the video data is played back in reverse; and

in response to a request to stop reverse playback, determining a replay starting position;

switching to a transmission playback mode;

setting automatically in response to a request to start playback of video data, an in-point at a position in the video data at which the playback starts, the temporary in-point is updated during reverse playback;

playing back, in response to the request to start playback, the video data;

setting, in response to a request to finish playback of the video data, an out-point at a position on the video data that is being replayed when the request is made; and

generating other video data from the video data of a section between the reset in-point and the out-point.

5. The editing method according to claim 4 , wherein the playback of the video data in the step of playing back the video data includes variable speed playback and pausing of the playback.

6. The editing method according to claim 4 , wherein generating the temporary clip of the video data includes generating a clip from the video data of a section between the temporary out-point and the temporary in-point.

7. The editing method of claim 4 , further comprising:

resetting the in-point, in response to a reset request, during the playing back of the video data at a position of the video data when the reset request is received.

8. An editing method, comprising the steps of:

switching to a preview playback mode;

forward playing video data for preview playback of the video data;

setting, in response to a request for reverse playback, a first reference point and a second reference point at a position on the video data that is being played when the request has been made;

generating a temporary clip of the video data of a section between the first reference point and the second reference point;

reverse playing, in response to the request for reverse playback, the video data, wherein a position of the second reference point is updated during reverse playback;

setting automatically, in response to a request for setting a third reference point, a third reference point at the second reference point at a time when the request for setting an in-point is made;

resetting the first reference point, in response to a reset request, during the playing back of the video data at a position of the video data when the reset request is received; and

generating other video data from the video data of a section between the reset second reference point and the third reference point.

9. A non-transitory computer readable medium comprising an editing program executable by a computer to carry out the steps of:

switching to a preview playback mode;

forward playing the video data for preview playback of the video data;

setting a temporary out-point and a temporary in-point, in response to a request for reverse playback of video data, at a position on the video data when the request was made;

generating a temporary clip of the video data of a section between the temporary out-point and the temporary in-point;

reverse-playing, in response to the request for reverse playback, the video data and updating the position of the temporary in-point of the temporary clip during reverse playback;

in response to a request to stop reverse playback, determining a replay starting position;

switching to a transmission playback mode;

setting automatically, in response to a request to start playback of video data, an in-point at a position in the video data at which the playback starts, wherein the in-point may be reset with a reset request during the playback;

playing back, in response to the request to start playback, the video data;

resetting the in-point, in response to a reset request, during the playing back of the video data at a position of the video data when the reset request is received;

setting, in response to a request to finish playback of the video data, an out-point at a position on the video data that is being replayed when the request is made; and

generating other video data from the video data of a section between the reset in-point and the out-point.

10. A non-transitory computer readable medium comprising an editing program executable by a computer to carry out the steps of:

switching to a preview playback mode;

forward playing video data for preview playback of the video data;

setting, in response to a request for reverse playback, a first reference point at a position on the video data that is being played when the request has been made, and further wherein the second setting means resets the in-point during a preview playback in response to a resetting request;

generating a temporary clip of the video data including a temporary in-point and a temporary out-point;
