The Play menu allows you to navigate through the file that is open in DVMP Pro. It also allows you to mark In and Out points that define a start and end point for the Burn-in and other tools.
Navigation differs slightly depending on the type of file that is open.
Play menu
For DV AVI, DV MOV and Raw DV files, you can start playback or pause it, frame step backward or forwards, and jump in either direction by 1 second or 1 minute increments. You can also jump to the previous or next scene.
For AVCHD, HDV, MOV, MP4 and MPEG-2 PS files, you can start playback or pause it, single frame step backward or forwards, and jump to the previous or next I-frame. It is not possible to jump between scenes so that part of the Play menu is greyed-out.
If an AVCHD, HDV, MOV, MP4 or MPEG-2 PS file is open, the Fwd 1 sec and Back 1 sec items are replaced with Fwd 1 I-frame and Back 1 I-frame.
All of the navigation operations are duplicated by keyboard hot-keys which are visible in the Play menu. You'll find the hot keys a lot quicker to use than the Play menu.
Mark In & Mark Out
Mark In/Out selection region
Mark In and Mark Out allows you to set the start and end position which is used by several of the tools. For example, if you want to time stamp a single video file, you can open it in the DVMP Pro player and click the Tools > Burn-in Time Stamp menu which will time stamp the whole file. But what if your video file is quite lengthy but you only need a few seconds of time-stamped footage from it - you don't want to wait for the whole file to be stamped when you only need a few seconds of it. You can use Mark In and Mark Out to set the start and end points of just the section of video that you want.
So after you open the file, pause playback, then drag the slider to the beginning of the region that you actually want - use the left and right cursor keys to step to the exact frame if you wish. Then click Play > Mark In (or press the [ key). You will see a triangluar "in" marker appear beneath the slider. Then drag the slider or frame-step to the end of the region you want, and click Play > Mark Out (or press the ] key). You will then see an "out" marker appear and the selected region between the in and out marks is highlighted in the slider's channel. Now if you click Tools > Burn-in, only the selected region will be time stamped - you will find this a massive time-saver!
The Mark In and Mark Out selection is also used by many of the other tools, so you can export metadata or extract audio for just the selected range.
You can clear the In and Out marks by clicking Play > Clear In/Out Marks.
You'll probably find it easier to Mark In and Mark Out by pressing the square-bracket [ and ] keys on the keyboard instead of clicking them on the Play menu.
