MIDI Time Code Video Player for Audio Workstations
VidPlayMTC is a simple and efficient application for playing video synchronised to MIDI Time Code (MTC). It uses FFmpeg, which is an Open Source library of tools for working with video and audio data in multiple formats. The application runs in Microsoft Windows and is able to open and play video files in any format supported by FFmpeg (as of August 2016).
If you have a video file formatted with any freely licensed codec, then VidPlayMTC will probably be able to open and play it.
- Syncs to MIDI Time Code (MTC) or MIDI Clock input.
- Loop mode may be set with loop points to cycle through a sub-section of the video.
- The viewport window is resizable and, optionally, the video may be viewed in a detached window or full screen.
- Video may be viewed at its original aspect ratio or scaled to fit a chosen window size.
- Plays the soundtrack if present within the video file, or it can be muted.
Requires Windows 7, 8 or 10 (64-bit). Will not run in Vista or XP. (Apple Mac version is not yet available)Software Delivery
Installs from a Microsoft Installer (.msi) compressed package, available from the downloads page.
MTC Frame Rate
Accepts MTC at 24, 25, 29.97 or 30 fps. Automatically detects frame rate from the MIDI input stream.
MIDI Clock may be used if the Master is not able to transmit MTC. A fixed tempo must be specified, matched to the Master tempo.
An audio output device must be specified, even if the video being played has no soundtrack. ASIO and MME devices are supported.
Using MIDI Loop Back
VidPlayMTC is intended for studio setups where two PCs are linked via MIDI cable (or by MIDI over Ethernet ). A 'Server' machine runs VidPlayMTC synchonised to a MIDI stream transmitted by a 'Master'. It is possible, however, to make a setup where the Master and the Server run on the same PC. To achieve this the MTC data is sent out on a MIDI Out device and looped back to a MIDI In.
The 'loop back' can be achieved in software, or with a physical cable. There are a couple of software options that I know of...
It may seem counterintuitive, but the MIDI Out port of an audio interface unit can be looped back to its own MIDI In with a MIDI cable. This works fine with my own Edirol UA-25, and that is how the demo video (at the top of the page) was created.
If all this seems a little complicated, you may find the VidPlayVST plug-in provides a simpler solution.
Usage Notes and 'Gotchas'
Checking for MIDI Input
The application includes a MIDI Watch window that shows the MTC or MIDI Clock data arriving at the input port. When video is playing MIDI events scroll rapidly through the window, timestamped in milliseconds.
Contention between audio devices
If running a 'loop back' setup, then both the Master application and VidPlayMTC will each need to open an audio device on the same PC. If VidPlayMTC is receiving MIDI but the video is not playing, then you should check which audio devices are being opened. It may not be possible for the Master and VidPlayMTC to share the same audio output.
Use MTC in preference to MIDI Clock
Some DAWs will allow transmission of both MTC and MIDI Clock. In this case select MTC only.
