1. Overview of INT NLE Tools

INT NLE Tools v1.0 for macOS is a tool set for making timecode easier to check during editing.
The current version provides two main features.

Pull-down TC Display.
When editing a 23.976fps timeline in Blackmagic Design DaVinci Resolve, you can check converted TC equivalent to 29.97DF / 59.94DF after 2:3 pull-down processing, for broadcast and similar delivery formats.

In INT TimeCode Tool, you can switch between Timeline TC, Dual, which displays the timeline timecode and converted timecode at the same time, and Converted, which displays only the converted timecode. By using INT_BurnIn (Fusion Title), you can also display the TC in the DaVinci Resolve viewer or video output.

Timeline TC Monitoring.
You can check the NLE Timeline TC in a browser on a tablet, computer, or other device on the same network.
Timeline TC Monitoring consists of three functions: Sender, Server, and Receiver. Sender sends TC from the NLE. In DaVinci Resolve, INT TimeCode Tool is used as the Sender. In Adobe Premiere, INT TC Sender for Premiere is used as the Sender. INT TC Server acts as the Server, relaying information received from the Sender to Receiver. Receiver is the browser display screen built into INT TC Server. It can be opened not only in a browser on the same Mac, but also in a browser on a tablet, computer, or other device on the same network.

The detailed role and usage of each tool are explained in the following chapters.

• Converted: Displays the converted TC at the center. Use this when editing at 23.976fps and checking TC for 29.97DF / 59.94DF.

Network Tools

Network Tools are settings related to Timeline TC Monitoring. Details are explained in 6. Timeline TC Monitoring.

5.3 Displaying TC on Video with INT_BurnIn

If you want to display the TC shown in INT TimeCode Tool on the DaVinci Resolve video as well, use INT_BurnIn (Fusion Title).

Place it on the DaVinci Resolve timeline as a Fusion Title, and adjust the display contents as needed. Select INT_BurnIn from the Titles category in Effects and place it on an upper track in the timeline.

INT_BurnIn is displayed relative to the upper right of the video. You can adjust the display mode, size, and other settings from the Inspector.

• Layout: Select the display format from Timeline TC / Dual / Converted / Horizontal Dual. This can be set independently from the INT TimeCode Tool display mode.
• Global Scale: Adjusts the display size.
• Position X: Adjusts the horizontal position.
• Position Y: Adjusts the vertical position.
• BG Opacity: Adjusts the background opacity.
• Start TC (Manual): Manually specifies the start timecode used as the reference for the BurnIn display when Sync From Plugin is not used.
• Sync From Plugin: Applies the timeline start TC and display settings from INT TimeCode Tool as of the time the Settings screen is opened. If you change the timeline start TC or related display settings, open the INT TimeCode Tool Settings screen, then turn Sync From Plugin on in INT_BurnIn, or toggle it off and on if needed.

During installation, INT NLE Tools removes older INT_BurnIn files and installs the current INT_BurnIn. If the older INT_BurnIn_Beta_1.0.1 is present, it is also removed during installation. For uninstalling, see 10. Uninstall.

5.4 Controlling DaVinci Resolve Playback from INT TimeCode Tool

Immediately after launch or after changing settings, INT TimeCode Tool may have focus, so DaVinci Resolve shortcuts cannot be used.

In DaVinci Resolve Preferences / System / Advanced, enter System.Remote.Control = 1, save, and restart. This allows playback/stop control from INT TimeCode Tool using the space key.

6. Timeline TC Monitoring

You can check the NLE Timeline TC in a browser on a tablet, computer, or other device on the same network.

6.1 Sender -> Server -> Receiver Flow

TC from the NLE is transferred in the order Sender, Server, Receiver.

Sender

The Sender sends the current Timeline TC from the NLE. In DaVinci Resolve, INT TimeCode Tool acts as the Sender. In Premiere, INT TC Sender for Premiere acts as the Sender.

Server

The Server relays TC and display state received from the Sender to Receiver. INT TC Server acts as the Server.

Receiver

Receiver displays TC by accessing the web server inside INT TC Server from a browser on each device.

6.2 Displaying Timeline TC in Receiver with TC Mode

Launch INT TC Server.

Press the start button to start the Server function.

Access the displayed URL or QR code from a browser to display Receiver.

Network / LAN URL selection

In environments with multiple network interfaces, use the Network menu in INT TC Server to select the interface that is on the same network as the Receiver device.

When you open the Network menu, you can check the interface name and IP address. The LAN URL is updated according to the selected interface, and the QR code is automatically updated to match the selected LAN URL.

To share the currently displayed Receiver URL manually, use the Copy button to copy it to the clipboard.

This setting does not change the address that INT TC Server listens on. It only selects the LAN URL and QR code shown to the user for Receiver access. If the URL does not open, check that the Receiver device is connected to the same local network.

Note: If Receiver cannot connect to INT TC Server, device-to-device communication may not be allowed on the network being used, before any INT NLE Tools settings are involved.
An internet connection is not required for INT NLE Tools Timeline TC Monitoring. What is required is that the machine running INT TC Server and the Receiver device can communicate within the same local network.
In company, broadcast facility, or studio networks, device-to-device communication may be blocked by security settings, even if the devices are connected to wired LAN or Wi-Fi within the same facility. For example, wired LAN and Wi-Fi may be separated, a guest network may prohibit device-to-device communication, or communication may be restricted by firewall or VLAN settings.
If the Receiver device cannot access the INT TC Server URL or IP address, ask the network administrator whether device-to-device communication is allowed. If the existing company LAN or studio LAN cannot be used, we recommend preparing an independent local network for INT NLE Tools and connecting INT TC Server and the Receiver device to the same network.
Network design, security policies, firewall settings, VLAN configuration, Wi-Fi isolation settings, and similar facility-specific matters are outside the support scope of this tool.

When you turn Sender ON in INT TimeCode Tool, DaVinci Resolve TC is displayed in Receiver.

Receiver display mode switches in sync with the Layout setting in INT TimeCode Tool.

Receiver is the browser display screen built into INT TC Server. It can be opened not only in a browser on the same Mac, but also in a browser on a tablet, computer, or other device on the same network.

In Receiver, switch between TC Mode and Clip Mode. TC Mode is the basic display for checking Timeline TC / Dual / Converted.

When using INT TC Sender for Premiere and using TC from Premiere, stop the Server, choose Premiere from the pull-down menu, then press the start button to start the Server function.

In Premiere, turn on the "Enable Premiere Sender" checkbox in INT TC Sender for Premiere to turn the Sender function ON. Receiver will then display Premiere TC.

6.3 Clip Mode

6.3.1 Displaying Metadata in Clip Mode

Clip Mode displays metadata at the stopped position when playback is stopped. In this version, it can display file name (File) / source frame number (Frame) / source timecode (SourceTC).

It is displayed by selecting Receiver Layout as Clip Mode in the INT TimeCode Tool Settings screen.

In INT TimeCode Tool, the shortcut for switching to Clip Mode is 8. The shortcut for switching back to TC Mode is 7.

Clip Mode does not follow frame by frame during playback like TC display. During playback, the metadata fields display "-".

6.3.2 Metadata Source in Clip Mode

In the INT TimeCode Tool Settings screen, Metadata Source lets you limit which video tracks are used to obtain metadata displayed in Clip Mode.

Auto displays metadata from the enabled clip on the highest track at the playhead position. Disabled clips, Generators, and similar items are skipped.

When you check specific tracks such as V1 / V2 from the pull-down menu, only clips on the specified video tracks are used as metadata display targets. Disabled clips, Generators, and similar items are also skipped in this case.

8. Migrating from INT TimeCode Tool v1.0.1

8.1 Positioning of INT TimeCode Tool v1.0.1 and INT NLE Tools v1.0

INT TimeCode Tool v1.0.1 was provided mainly as a standalone tool for DaVinci Resolve. INT NLE Tools v1.0 includes it as INT TimeCode Tool v1.2.

INT NLE Tools v1.0 for macOS is a suite that includes INT TimeCode Tool, INT TC Server, Receiver, INT TC Sender for Premiere, INT_BurnIn, Uninstaller, and other components. With INT TimeCode Tool v1.2, in addition to Pull-down TC Display for checking TC in DaVinci Resolve, you can use Timeline TC Monitoring to check Timeline TC on external devices.

8.2 Preserving a v1.0.1 Environment

If you want to continue using INT TimeCode Tool v1.0.1, or keep the option to return to it as needed, we recommend that you preserve the old download links, installers, and distribution files that you already have before migrating. INT NLE Tools does not guarantee that old v1.0.1 distribution files will be provided again.

8.3 Mixing Old and New Versions

In principle, we recommend not mixing the old standalone INT TimeCode Tool and the new INT NLE Tools version in the same environment. This may cause unexpected behavior in DaVinci Resolve.

8.4 Returning to v1.0.1

To return to INT TimeCode Tool v1.0.1, first uninstall INT NLE Tools, then return using the v1.0.1 distribution files you have preserved yourself. See Chapter 10 for uninstalling.
