¶ Introduction
Digital Camera Systems LDT-R2 and LDT-V Series are multi purpose lens encoding systems that can be used for injecting lens data into the RED Family, Panavision DXL, and Sony Venice as well as internal recording for Film cameras and other digital cameras that do not support injection recording. The LDT-V Series can also live stream lens data into virtual production software such as Unreal Engine either wired or wirelessly (LDT-RX1 reciever required for wireless data transmission).
The LDT-R2 and LDT-V Series reads the Focus, Iris and Zoom motor movements from a FIZ motor controller unit and translates this information into human readable encoded data.
This lens metadata can be written directly into the raw camera files in real-time (injection recording) or recorded onto a MicroSD card (Internal SD recording), this can also be streamed live for use in Virtual Production (VP) applications.
This manual is divided into three main sections depending on how the metadata is being recorded. Please go to the appropriate chapters.
Please note, the LDT-V Series has all the functionality of the LDT-R2 but with additional streaming capabilities. In order for the manual to be succinct, the LDT-R2 is referenced when describing functions and features of both models, whereas the LDT-V Series is referenced when it only applies to the LDT-V Series.

CLIPSandFIRMWARE
¶ Setting up the Preston MDR and Hand Unit
It is essential that all Preston MDR and HU firmware is updated prior to building any lens tables or F-Maps. There is a known issue where auto lens select will not work when the Preston units are not updated.
All F-maps must be made on one hand unit and shared to the other units.
Save all F-Maps to the "Other > User" folder to ensure auto lens select feature works.
The Preston HU4 cannot input '.5' half lengths. This means that Auto Lens Select should not be used with these F-maps as they would be inaccurate.
- Setup the Focus / Iris / Zoom direction for normal use on the Preston.
- For lens encoding connect the iris and zoom handsets (not required for normal operation).
- Ensure the motor directions are correct on all handsets.
¶ Serial Loop Through for 3rd Party Devices
If no serial port is available on the MDR, the LDT-R2 has a serial loop through port to connect 3rd party devices. Connect the 3rd party device to the serial port of the LDT-R2 and ensure loop through is enabled:
- Choose:
Menu > Settings > SERIAL port > MDR LOOP
¶ CineRT
There is a known issue between the CineRT and LDT-R2 where data will not show up when connected. If this happens, check the CineRT is set to
Serial Out > MDR. If this does not resolve the issue, connect everything up as normal then power cycle the LDT-R2.
-
If used with a Preston lens control workflow, the LDT can power the CineRT through it's serial pass-through via an MDRP cable.
-
If using an a lens control workflow that requires an LCUBE, the CineRT can be powered either by connecting it to a RIA-1 or connecting it to a second LCUBE.
The LCUBE which is connected to the LDT unit MUST be at the end of the chain.
¶ Using a Light Ranger with the LDT-R2
It is recommended that the Light Ranger is used through the serial port of the Preston MDR-3 or MDR-5.
If the LDT's serial pass-through is required, then please get in touch with DCS.
- Email: info@dcs.film

¶ Rigging and Settings for a Smart Lens
Follow the instructions above omitting the Preston MDR rigging and Data Source setting. Use the rigging and settings found here to complete set-up.
¶ Internal Recording
Refer to this section if you are recording data in the LDT-R2. This mode is available for all types of cameras. LDT-R2 requires shutter pulse or record tally from the camera in order to start recording data.
A constant external timecode source must be provided to the LDT-R2 by a timecode generator. The LDT-R2 will not receive timecode directly from a camera. This is by design as timecode is lost when going off speed.
Encoded data is recorded on the MicroSD card.
The SD Card MUST be formatted each day after the data has been backed up.
Please make sure to backup the MicroSD data on a computer after each shooting day in order to avoid data loss.
¶ Recording Format
Frame by frame (FbF) data is recorded onto the MicroSD card’s CLIPS folder, as a CSV file type. Everytime the camera runs, a new CSV file is created.
The CSV file is matched to the timecode. A new line gets created at every timecode interval.
Read ‘Appendix 2: Internal Recording - CSV File Structure’ to learn more about it.
¶ Setting up the LDT-R2
Select the desired projects FPS.
- Choose:
Menu > Settings> Project FPS
Choose between:23.98FPS, 24FPS, 25FPS, 29.97FPS, 30FPS
Project FPS must match Timecode FPS.
If running multiple LDT-R2s at once, setting the corresponding camera index is advised.
- Choose:
Menu > Settings> Camera index > A, B, C, ...
Set the roll number on the LDT to the corresponding roll loaded on the camera. This does not require removing or changing the SD card. To set the roll number:
- Choose:
Menu > Settings> Roll > 001, 002, 003, ...
It is essential to change the roll on the LDT every time the roll is changed on the camera so they match. This information is used to link the data in post production.
¶ Recording and Timecode signal
When Internal Recording is set, the LDT-R2 changes the Lens Details homepage to fit the TC and REC icons.
After connecting the timecode cable from a timecode generator device into the TC port on the LDT-R2, the Lens Details homepage will show a stable TC icon meaning that the LDT-R2 is receiving a good timecode. A flashing TC icon means that the LDT-R2 is receiving timecode but at the wrong FPS, change the LDT-R2 or the timecode generator project FPS to match. No TC icon means that the LDT-R2 is not receiving any timecode, check the cable direction if using a unidirectional timecode cable.
When recording a REC icon will pop-up under the TC icon.
¶ Start/Stop Recording from the Preston HU3
If the LDT-R2 cannot receive a record trigger from the camera, then recording can be controlled from a Preston HU3.
To enable the Preston start/stop functionality, on the LDT-R2:
Menu > Settings > Mode > MDR, SD Card- To start recording from the HU3 press the “Camera” button,
- To stop recording press the “Camera” button.
To verify the LDT-R2 is recording:
- REC will appear on the main screen of the LDT-R2 and,
- The LED above the "Camera" button on the HU3 will light up.
When manually starting and stopping the LDT-R2 it is important to limit the clip lengths to match those being recorded by the camera. Recording all day (for instance) can result in loss of data.
¶ Manual Recording on the LDT-R2

¶ LDT-V Series - Streaming Data for Virtual Production
The LDT-V Series can live stream data to the DCS Unreal Engine Plugin. Information on installing and setting up the plugin can be found here:
https://support.dcs.film/DCSUnrealEnginePlugin
DCS also has a lens data emulator to assist with initial set-up and troubleshooting. Instructions on where to find this and how to set it up can be found here:
https://support.dcs.film/en/LDT-Emulator/DCSLDTEmulator
If manually moving the lens axes or using a motorised remote focus system other than a Preston MDR or ARRI LBUS system, the LDT-E Series can be attached to the lens to report lens movement back to the V Series. More information on setting up the LDT-E Series can be found here.
Depending on the production’s requirements, the LDT-V Series can stream, stream and inject or stream and record lens data.
¶ Wireless Data
The LDT-V2 can support both wired and wireless connections. The LDT-V1 is a wired only solution.
The DCS wireless system requires a DCS receiver (LDT-RX1), it cannot be paired with 3rd party routers or products. Contact DCS for more information.
The LDT-V2 contains a powerful transmitter module that works at sub Wi-Fi frequency. This will cut through the wireless noise of a busy set to deliver excellent results when paired with the LDT-RX1 receiver unit. Manual for the LDT-RX1 can be found here.

¶ RAW Encoder Values
Menu > Settings > Advanced > DCS Protocol > RAW encoder > Disable/Enable
¶ Tilt/Roll Data
Menu > Settings > Advanced > DCS Protocol > Tilt/Roll > Disable/Enable
¶ Connection Information
Regarding issues with connecting the LDT-V2/LDT-RX1 to network equipment:
The DCS devices auto negotiate on Ethernet upto a rate of 100Mbps. The network equipment must be able to negotiate down to this rate. Equipment limited to 10G/1Gbps may require additional interfacing.
¶ Lens Mapping
Full guide for lens mapping can be found here: Lens Mapping Guide
Creating accurate map files for each lens is vital when using the LDT.
A step-by-step mapping guide can be followed to ensure that maps are built correctly.
After lens maps have been created, users can manually choose them from the LDT menu, if auto-lens selection is deactivated.
If auto-lens selection has been enabled and Preston Hand Unit information was used to create the map, the LDT will automatically load the corresponding map whenever there's a new F-Map selection on the Preston Hand Unit
¶ Testing the Lens Table
Prior to saving the lens map we suggest testing its accuracy. This can be done by pushing down the joystick when in one of the axes to enter the test window. Compare what is displayed here with the engraved marks on the lens to ensure the table is accurate.
Press the back button to go back.
¶ Pre-built Lens Table for Testing
The LDT contains a pre-built Lens Table intended for troubleshooting purposes.
- Choose:
Menu > Edit Lens > DCS Zoom test 11-110 (1)
This can only be selected with Auto lens select turned off.
¶ Saving a Lens Table
Once all the required values have been encoded, click on ‘SAVE’ to save the lens table.
A message will prompt upon successful completion.
¶ Edit a Lens Table
A lens table can be edited. New points can be added, existing points can be removed or a lens table can be permanently flipped.
- Choose:
Menu > Edit Lens
¶ Deleting a Point
If a point gets added by mistake or needs repositioning it can be removed.
In order to delete an existing point push the joystick to the left. Move the controller to the desired point. Push the joystick to remove the point.
Press the back button to go back.
¶ Flipping a Lens Table
If an axis map needs to be permanently reversed push the joystick to the right, then push the joystick to confirm.
If a map needs to be temporarily reversed we suggest to reverse the direction of the motor.
- Choose:
Menu > Motor direction
¶ Using an LDT-E Series Lens Data Encoder
Camera operators may wish to manually control the zoom (or other axis) instead of using a motor that feeds data to the MDR. A lens enoder can be used with a motor, or in replacement of, allowing the LDT-R2 to still gather the lens movement data.
DCS has its own brand lens data encoder called LDT-E Series. These are plug and play devices so there is no need to create a new or separate lens table when using them.
Note: the direction of the motor might need to be reversed: please go to the Changing the Motor Direction chapter.
A video tutorial explaining the set-up of the LDT-E1 can be found here
¶ Setting the axis for the Encoder
The LDT-E Series have a manual switch to set the axis to Focus, Iris or Zoom.
¶ How to calibrate the Lens Data Encoder
If using an LDT-R2/LDT-V Series without a Preston system:
- On the LDT-R2/LDT-V Series choose:
Menu > Calibrate LDT-E
If using an LDT-A2/LDT-M2 with a Preston system:
- On the LDT-A2/LDT-M2 press the blue button for 3 seconds
If using an LDT-R2/LDT-V Series with a Preston system:
- On the MDR3/MDR4 press the calibrate button
Then manually rotate the axis which is attached to the Lens Data Encoder from one end, pause for a second, then rotate to the other end. The LDT-E Series should now show as calibrated in the on-screen display.
¶ Changing the Motors direction
If for rigging purposes a lens motor or lens encoder need to be reversed:
- Choose:
Menu > Motor directionand selectReverseon one of the axes.
¶ Transferring Data between LDTs
Specific data can be shared between LDT-R2's and the LDT-V Series to save time and ensure consistency across multiple set-ups.
¶ Transferring Lens Tables
Lens tables can be shared between all LDTs with a Micro SD slot. Please note that lens tables made using the LDT-A2 and LDT-M2 on the ARRI LDA system are a different file format and cannot be shared to the LDT-R2/V Series (and vice versa).
The LDT-R2 saves individual lens tables as .XML files to the MicroSD card. If multiple LDT-R2s are being used, these lens tables can be shared between devices.
-
Insert the MicroSD Card with the lens tables on into a computer,
-
Copy the .XML files from the "LENSES" folder onto the hardrive,
-
Insert a formatted MicroSD card (how to format a MicroSD card for the LDT-R2),
-
Copy the .XML files to the "LENSES" folder on the new MicroSD card.
Backup the "LENSES" folder when any new lenses are added to the on the MicroSD card to avoid data loss in case of corruption.
¶ Transferring an LDT Configuration
All settings of a unit can be downloaded to the MicroSD card and uploaded to a different unit to mirror all settings.
Config files can only be shared between specic models. I.e. LDT-R2 config files will work with LDT-R2 units, but LDT-V1 config files will not work with LDT-V2 units.
When uploading config files to a unit all original settings of that unit will be lost. Either back-up the original config file or make a note of device specific settings such a network addresses and camera index.
To save the config file:
- Menu > Save Config
This will save a text file called 'Config' on the Micro SD. If a config file is already on the MicroSD it will overwrite it.
To share the config file with a different unit:
- Eject the MicroSD card from the original LDT-R2
- Insert the MicroSD card into the next LDT-R2
- Menu > Settings > Load Config
- Follow the on-screen instructions
¶ Lens Table Files Naming Convention
Each .XML file is named after the lens brand, focal length and last 3 digits of the serial number. Examples:
AOZ24987.XML
Angenieux Optimo Zoom 24-290mm sn.11218987
CVZ25324.XML
Cooke Varotal Zoom 25-250mm sn.5640324
ZU135767.XML
Zeiss UltraPrime 135mm sn.8185767
AS047211.XML
ARRI Signature Prime 47mm sn.9899211
¶ Lens Database
If the user decides to not use F-Map, the lens database can be organised as a list or as folders.
- List: LDT-R2 display.
- Folder: LDT-R2 creates a folder structure based on lens brand, type and a single file for each lens in the root of the MicroSD card.
¶ Shooting Tests
It is essential that a test is done for each workflow established on the show before shooting. The tests involve shooting with the LDTs set-up, followed by a round trip of the data where the metadata (however recorded) is married to the EXRs so it is available for vendors in post. This should be coordinated between VFX, Camera, the Lab, Pulls house and Vendors. The goal of these tests are to provide reassurance that all data will be accurate when recieved by vendors and to catch any issues in the pipeline.
DCS can be involved in any pipeline discussions either by attending an initial meeting or being looped into emails if additional support is required. Email info@dcs.film.
Below are the descriptions of how to do the camera portion of the tests.
Allow approximately one hour per camera type being used on the production.
¶ Injection Recording
The test will involve recording the metadata with a camera and recording a separate feed from the camera with an overlay to verify the data is correct at the final stage of the test. We recommend using a zoom lens (if any are being used during the shoot) in order to check all three axes.
¶ Internal Recording on Film Cameras
If the camera cannot be fed a timecode, such as with film cameras, it is essential to display a digislate or, at the very least, a timecode within every take. This ensures there is a reference to link the film with the lens data clip.
¶ Setting up the Test
- Encode a lens and test it (see Programming a New Lens Table),
¶ Shooting the Test
- Shoot test footage in camera and record separate overlay feed at the same time,
- At the time of pulls, data is merged into the EXR,
- Compare the metadata of the EXR file to the overlay footage.
¶ Internal Recording
Three tests are recommended and will involve recording a visual source of the data in the camera with the LDT-R2 recoding the metadata as a sidecar to verify the data is correct at the final stage of the test. DCS recommend using a different lenses for test one and two and a zoom lens specifically for the third racking test (if any are being used during the shoot) in order to check all three axes.
¶ Setting up the Tests
- Rig and set-up the camera and LDT as per the instructions in this manual,
- Encode a lens and test it (see Programming a New Lens Table),
- Ensure the LDTs Camera Index and Roll number match the current test mag:
- On the LDT-R2 Choose:
Menu > Settings > Camera IndexSet to T or what letter the test mags are labelled with,
Menu > Settings > Rolland set to the current test mag
It is very important that the clip number of the camera mag and LDT clip number match at all times. Do not run the camera without the LDT attached.
For Each test a written visual representation of the FIZ values is required, for instance a clapper board with the lens values written on it.
¶ Test One - Static Test (Prime or Zoom)
- Set each axis to a value e.g. T-Stop 4, Focal length 22mm, Focus distance 6ft,
- Write on the board the test number, the lens name, and the values of each axis,
- Record a 10 second clip
¶ Test Two - Static Test (Different Prime or Zoom)
- Set each axis to a different value than test one e.g. T-Stop 5.6, Focal length 45mm, Focus Distance 30ft,
- Write on the board the test number, the lens name, and the values of each axis,
- Record a 10 second clip
¶ Test Three - Racking Test (Zoom Lens)
- Set each axis to a value e.g. T-Stop 4, Focal length 22mm, Focus Distance 6ft,
- Write on the board the test number, the lens name, the static values of each axis, and the range of the span of each axis (e.g. Iris T1.8 - T22, Focus 16"-Inf, Zoom 15mm - 30mm)
- Record a clip,
- During the recording, rack each axis one at a time, starting at the static number rotating the axis from one end to the other and returning to the static number.
After completing the tests remember to set the Camera Index on the LDT-R2 back to the corresponding camera letter.
¶ Processing the Tests
- The camera mags should be sent to lab with the microSD sidecar files from the LDT,
- During the VFX pulls proces, merge the CSV files to the EXR,
- Compare the metadata of the EXR file to the data in the test footage - this should be verified by a VFX vendor.
Please be aware that the extreme values in the CSV/EXR during the racking test may exceed the values in the image slightly. Most lenses have hard stops that go further than the values written on the lens. This is normal and should only flag an issue if the values far exceed the values displayed on screen.
