Main interface

White Dash was designed to make selective cuts in the new Panasonic GH5 6K photo mode and other 4K and beyond video clips before batch conversion - reducing compute time and disk storage needs. Selections are then appended to a shot list one at a time until ready to be saved to either a Simple EDL (.sedl) for import into Convert V4 for transcoding, or alternately saved to a standard CMX3600 EDL for use in pro editing applications such as DaVinci Resolve, Adobe Premiere Pro or Avid Media Composer


Use the right-click context-sensitive menu to import a clip from the standard Windows open file dialog



White Dash controls are much like any other player with play, stop, frame reverse and frame forward along with in and out mark buttons. Use the [ and ] transport buttons for moving directly to the first or last frame instantly without scrubbing

The idea is to select portions of each clip that you want to work with - and then convert only those portions rather than convert entire clips. This can save an incredible amount of computer render time - and in the case of high-bitrate codecs can save a huge amount of disk space. You trim your clips and save the selections for either conversion to other formats or for importing into other pro applications

Marked regions are shown by [ and ] marks that identify the range selected


When White Dash is active and in use it will lock-in as the top most window and will prevent interaction with other windows on screen. This keeps the transport responsive to keyboard shortcuts and control surface commands. Click the blue lock icon at the bottom right side of the main interface to unlock and interact with the main viewer and other windows.


TC Panel

The timecode panel keeps track of current timecode as you scrub or play through a clip
The total frame count is displayed right beside the timecode panel



As you mark in / out regions, use the [ add cut ] button to record your selection to the shot list. Every new set of in / out marks gets appended to the shot list. You can record multiple cuts from a clip into the shot list or mark several clips for a large batch conversion in a single shot list. Once completed you can save the shot list to SEDL for use in V4 or as a standard EDL


Clip resolution, framerate, duration, timecode start, timecode end, timecode span and total number of frames information is displayed directly within the interface. Hover over a control for tool tips

Click this button to select a playback aspect ratio - perfect for anamorphic or DCI work!
A drop-down list will appear with the following selections;

4:3 | 16:9 | 1.85:1 | 2.35:1 | 2.36:1 | 2.39:1

Plays the clip in a continuous loop until unchecked


Click the "grab frame" to save a full-frame TIFF, PNG, BMP, JPG or WMF image of the current frame

screen grab


Shot List

The shot list contains entries of all the clips and the in / out ranges along with timecode information for exporting to EDL. To work with Convert V3 it is necessary to export to S-EDL. You can then import that S-EDL into Convert V4, select the conversion of choice and batch-convert the selected ranges from each clip. (Convert V4 cannot import standard EDLs)

You can remove individual entries from the shot list at any time. Use the right-click menu to remove selections, save to S-EDL or EDL and clear the shot list for a new S-EDL


On the right-hand side of the main interface is the transparency slider. Double-click the main view window to go full screen and then adjust the transparency to minimize the distraction for your edit while keeping the interface where you can still work with it easily


White dash uses the MPV command-line player for viewing video clips and is compatible with most formats including XAVC and handles 8K resolution and beyond. MPV is also hardware accelerated so playback is smooth even with limited computer resources






White Dash can be driven directly by MIDI signals provided by any MIDI-capable device including iPhone and Android


Right-click and select "Preferences"

Click the MIDI Control Surface icon to enable the current MIDI In device. Use the MIDI interface selector drop-down to select from multiple MIDI devices


Then click the MIDI icon to enable or disable




The following functions are currently enabled for the following MIDI notes are:

Play / Pause - G1

Frame Back 1 - C1

Frame Forward 1 - D1

Mark In Point - E1

Mark Out Point - A1

Add Cut to Shot list - B1

Go To In Point - C2

Go To Out Point - D2

Lock to Front - G#1

Loop Playback Toggle - C#1


White Dash listens to MIDI Omni - all channels and should work with any MIDI capable hardware


For use with iPad or iPhone, grab the TouchOSC app from the iTunes store

Once installed - download a template for direct use with White Dash here

Use iTunes to copy the template to the OSC app


To easily connect your iPad to White Dash, download rtpMIDI from here and install with default settings

Once installed, open rtpMIDI and start TouchOSC on your iPad

(More detailed setup information available from rtpMIDI)

You should see your device listed in the Directory panel - highlight and click "Connect"

Your iPad is now connected - the MIDI name of the new virtual MIDI port provided by rtpMIDI is also the Local name of the host PC

If you have multiple MIDI devices installed, be sure to select this MIDI device in the White Dash MIDI drop-down list




For interactive display including running timecode, in and out marks, cut length, frame number and X-Ray mode you will need the ip address from your iPad which can be found in TouchOSC under the Core MIDI Connections


Right-click and select "Preferences" to open the MIDI Configuration Panel

Enter the ip address of your iPad and select the MIDI device you wish to use (if multiple interfaces installed)

Hit enter to commit the changes


You can find the ip address of your iPad in the TouchOSC Core MIDI Connections under "Local IP address" - do not enter the Host address


White Dash requires the Incoming port in TouchOSC to be set to port 5220 as shown below

The outgoing port can remain unchanged



iPad Config


Once assigned and your iPad is connected via rtpMIDI, click the MIDI icon at the bottom right of White Dash to start the MDI connection

Your iPad should now be able to control the White Dash interface and provide realtime feedback

Additional MIDI implementation and documentation coming soon...

White Dash does not have the ability to seek to the in or out points - hold down on the small double arrows icons to move forward or backward quickly through the clip then use the sngle frame arrows to zero in on a frame

The trackbar does not have the ability to scrub - use the same procedure as above to move through the clip by

1 second increments
