RedLapse Time Lapse Controller App For RED DSMC Cameras
Now Available on the Apple iTunes App Store.

RedLapse is a Time Lapse controller for RED Dragon, EPIC and SCARLET digital cinema cameras. It allows you to quickly and easily adjust the necessary settings for filming time lapse scenes. It will calculate scene lengths and real time recording lengths for you at any RED frame rate and playback rate. It will automatically start and stop recording and give you countdown and count up info while filming. It also allows you to change Aperture, Shutter Speed, ISO, REDCODE compression and Color Temperature from within the App.

The App controls your camera over a WiFi connection. To use the App with your RED DSMC camera, you must have a WiFi link via hardware such as the REDLINK BRIDGE or OFFHOLLYWOOD WiFi adapter.

Here is a direct link to the App's page on the Apple iTunes App Store:

The Time Lapse tab is the heart of the App. On this screen, you set times and frame rates and activate recording. There are several different methods that you can use depending on what work flow you prefer. Here is a brief description of each of the buttons and fields.

The first field is the Time Lapse Frame Rate. When you tap this field, a picker appears that allows you to set the desired frame rate. It follows the RED convention of displaying in white text if the frame rate is equal to the connected camera's project frame rate and in yellow text if set to any other frame rate (vari-speed). After you have chosen a frame rate, tap the "Done" button accept the change and hide the picker. Only valid frame rates that you can actually use based on the camera settings will be selectable. Inappropriate frame rates will be grayed out (more on this later). The frame rates may be limited by camera settings such as Shutter Speed, REDCODE settings, Project Format, etc.

The segmented control labeled "Playback Frame Rate" is initially set to the connected camera's project frame rate rounded up to the next whole number value. For instance, if your project frame rate is 29.97 fps, this segmented control will show 30 fps. This value is used to compute finished scene length seconds and frames. Fractional frame rates are insignificant for this type of calculation, hence the round up for simplicity. The appropriate segment is set when the camera is initially interrogated. It also changes if you choose a different project frame rate on the connected camera. Additionally, you can set it to another value that does not match the connected camera's project frame rate if you wish. If you change this setting, it does NOT change the project frame rate of the connected camera. It is merely used as a constant for certain computations.

The two fields below the "Desired Scene Length" label allow you to set the length of your finished scene in either seconds or frames. If you enter seconds, it will compute frames (and real time recording length). If you enter frames, it will compute seconds (and real time recording length). Seconds resolve to 1 decimal place. Frames are whole numbers. You enter one value that you want, it figures the rest. The Time Lapse Frame Rate and Playback Frame Rate are used to compute these fields. To change one of these values, tap on it and a keyboard will pop up. When you are finished, just tap anywhere outside the keyboard and it will retract.

The field labeled "Real Time Scene Length" tells you how long you need to record to get the desired finished scene at the selected frame rate. You can also work backwards if you wish. If, for instance, you know that you want to record for exactly 5 minutes and 30 seconds, you would enter 00:05:30 in the real time field and it will use the Time Lapse Frame Rate and Project Frame Rate to tell you what the length of the finished scene will be in both seconds and frames. If the finished scene length is too long or too short for your needs, then change the Frame Rate and it will recompute a new finished scene length for you. Like the "Seconds" and "Frames" fields above, to change the value, tap on it and a keyboard will pop up. When you are finished, just tap anywhere outside the keyboard and it will retract. Note: You must enter this field in the 00:00:00 format. If you want 3 minutes, you must enter the leading and trailing zeros as such: 00:03:00.

The "Record" button will begin the recording. If you didn't enter anything into the "Desired Scene Length" fields and the "Real Time Scene Length" is empty, then the Record button acts as a remote start/stop toggle with active counters for scene length, total frames recorded and real time recording duration. It will record at whatever Time Lapse Frame Rate happens to be set, and continue recording until you tap it again. While recording, the "Seconds" and "Frames" is computed based on the TimeLapse Frame Rate, and the "Real Time Scene Length" field shows you how long you have been recording. In this mode, its up to you to start and stop, but the app will give you running totals. This is handy if you want to record something like slow moving clouds. You just have to set a low frame rate, 1fps or 2fps, then tap the record button. You can watch the clouds and make sure they are doing something interesting, and stop when you have a long enough scene for your purposes.

If, however, you have entered a "Frames" or "Seconds" value, the App will do all of the timing for you. As you press record, you will see the Real Time Scene Length counting down towards zero and the finished "Seconds" and "Frames" counting up. At the end of the Real Time Scene Length (when it reaches zero), it will automatically toggle the recording off for you. You can abort in the middle of a recording just by taping the Record button to cancel the timer, stop the camera and reset all of the fields to their starting values.

The final button on the bottom of the screen will reset the connected camera to its original Project Frame Rate. This allows you to quickly transition back to normal camera mode if necessary.

The Camera Settings tab allows you to make quick convenient adjustments to useful camera settings without having to touch the camera. A segmented control shows five possible settings: Aperture, Shutter, ISO, REDCODE and Color Temperature. The currently displayed segment is highlighted and it's value is shown in the field below. Tapping on a different segment with show a different setting's value. To change a value, tap directly on the value and a picker will appear for you to choose a new value. After you have chosen a value, tap the "Done" button accept the change and hide the picker.

The three top row segments are the most important as they have the most immediate affect the image quality. REDCODE also affects quality, but you probably won't be changing it too often at this point unless you are doing an extremely long time lapse. Color Temperature is strictly Metadata and here for convenience.

The remaining SSD and Battery levels are self explanatory.

The Histogram is displayed to assist you when changing exposure related settings.
