LTC Convert (AUXTC) € 135,00


Current version: 5.1.8 for Mac, 5.1.6 for Windows
Note, These versions have a bugfix for setting TC on QT sources,
and support for input video with 16 audio tracks.

This util reads LTC timecode inside video or audio files, and can either set a new timecode, re-wrap to Quicktime or MXF, or transcode to Prores, including external sound if needed.
It supports a tremendous amount of different formats / codecs.

It can be used either to sync multiple cameras, or aid in dual system recordings.
For dual system sound, instead of creating / altering video files, it can also set a new timestamp on BWF files so they are in sync with the normal video timecode instead of the LTC.

If you don't know what this is about: AUX TC is 'normal' audio timecode, but recorded on one of the normal audio tracks. It also stands for a second (or third) TC track, no matter the way it is stored (yes, this is quite confusing.)

Why would you want AUX TC?
If you do a multicamera shoot and you want to sync up the different reels fast, you normally lock the timecode of all the cameras. Problem, cheap cameras do not have this option.
Even the Sony FS7 does not have a TC input!

What you can do is broadcast a TC signal and record it on one of the audio tracks.
Then use this applicatin to read out and convert it to usable TC for post-production.

Another example, if you shoot a music video, you probably play back a CD of the song while shooting. Create a CD with one channel of the song, and put TC on the other, record both on the camera. Not only do you have a reference to the song, you also instantly know where to put the take on your timeline.

Main features include
  • It decodes LTC if present on one of the audio channels.
  • It can merge BWF files with QT video, based on source or AUX tc tracks. (And of course the BWF TC)
  • Option to re-wrap clips to Quicktime, if needed with external audio
  • Option to export to ProRes, if needed with external audio
  • Option to alter the TC of the original QT's
  • Option to alter corresponding BWF files so their timestamp matches source TC instead of audio TC
  • Batch processing of multiple clips
  • Optional, there is a customized version that works as a commandline tool

What's new:
  • Added 16 track snd on video
  • Bufix on 'set found TC on source'
  • Fixed a sync issue on sources with AAC audio
  • Adde an option to sync if there is a FPS mismatch
  • Fixed a bug on sources with a FPS over 30
  • Added Userbits decoding to batch process multiple shooting days
  • Added a Doubleclick function to show more info on loaded video / BWF
  • Added display of BWF track names in the Patch window
  • Way more codecs / camera's supported
  • Drag and drop support
  • Improved accuracy. It's now accurate up to 1/500 of a second
  • Better export subfolder selection
  • Better ReelnameFromFolder selection for large batches

The original idea was developed by Georg Misch, and further development & bug testing was carried out with Georg Misch and the students of the Filmsound Department at the Institute for Electro- Acoustics, University of Music and Performing Arts in Vienna, Austria.


Youhouuuu it works!
Now I have to ask my producer to buy your wonderful product! ;)
The best support EVER!

You saved my 4 weeks of audio tc for a docu! Everything stamped correctly!
- Tomasso Ferrari,

I love it. I do a lot of multi-cam shoots/edits with DSLR's usually with multi-tracked audio (bands and stuff) I send LTC to the camera's via wireless in-ear transmitters/receivers. Sometimes it's long continuous shots, sometimes hundreds of shorter clips. Use LTC convert to read the code and stamp the files. It's wonderful. :-)
