Default Timecode– Sync by satellite product. EDIUS support?

I found another new timecode-sync product coming soon to the market. Unlike the products made by Tentacle, Denecke, UltraSync, Horita, BETSO etc which all use an accurate master clock to jam sync to, but this new product uses GPS and other satellite signals as the master clock. The product is called: Dish Timecode see here https://www.kickstarter.com/projects...very_category#

These devices have been a great low-cost solution for muti-cam or external audio recording timecode syncing. The only problem is all these products output the timecode in the LTC format onto an audio track and currently only DaVinci Resolve & AVID Media Composer support LTC timecode. Allowing both video and audio tracks to be synced.

There has always been work around software available for customers using NLEs that don’t support LTC, but it requires you to create new video & audio files. The company that makes the product Dish Timecode have developed a free, open-source application called LTCsync which can run on Windows, Mac & Linux to read the LTC format and generate a synced timeline. See here https://github.com/arikrupnik/ltcsync/releases

Does anybody know if EDIUS 9.5 will finally support LTC timecode syncing?

Never mind about EDIUS support first - have you thought of one really obvious limitation of using GPS satellite signals? This system won't work if you are recording indoors.

My post was only making EDIUS users aware that there's another muti-cam/audio syncing product on the market that uses LTC timecode and I was asking if anybody knew if EDIUS 9.5 will finally support LTC. I personally hope to buy the Tentacle system if EDIUS will support LTC timecode.
I took the following text from the FAQ in the Kickstarter page (see the link in my previous post)

Does it work indoors?
Yes, with some exceptions. RF design and signal processing algorithms have come a log way in the last few years. Modern front-ends can decipher signals that looked like noise to older receivers. DISH works well in most residential and office buildings. Environments that are challenging are windowless metal buildings. As a rule of thumb, if your phone can determine its position, DISH can get a signal.

What happens if DISH loses satellite signal?
Does it have an internal clock?
Yes. DISH has an onboard TCXO (just like the Tentacle system). If you lose satellite lock, the TCXO takes over and DISH continues to output accurate timecode.

I have been transmitting timecodes and receiving the same over ISM 2.4Ghz band for many years - inside concert halls and theaters. One master clock to transmit (one Ambient master clock) and the rest of the equipment locks into the transmitter by using Timecode Systems transmitter and receivers. I have tested it to more than 100m - without problems.

Initial editing of these videos and audios is sync'ed using Davinci RESOLVE - it is free software anyway. Then I transfer the output over to EDIUS. If and when EDIUS supports timecodes - I will be more than happy to remove Resolve from the equation.

Great video and he was inside. Shows signal wasn't a problem.

Prices of the units (Tentacle Sync) are comparable to Timecode Systems miniTrx+ and miniRx.

I think in practice - both systems will work. Tentacle Sync systems are based on individual units having a separate (but accurate) clocks. With Timecode Systems - you have one unit acting as the master - which transmit the timecodes and all other units genlocked to that master (by receivers). Even if the master's clock drift after an interval of time, it does not matter - as all other units are locked to that master.

Both systems won't work in EDIUS currently - because it does not support Timecodes. I have to use Resolve first - then export the sync'ed videos and audios to EDIUS for further editing. EDIUS multi-cam implementation is very good.

The syncing functions in Edius are being worked on. There was a preliminary preview at NAB, and hopefully we will see this fully implemented sometime in the next 3-4 months.

I didn't find any information that the future EDIUS 9.5 version will support LTC timecode (recorded audio timecode pluses). The company that makes the product Dish Timecode have developed a free, open-source application called LTCsync which can run on Windows to read the LTC format and generate a synced timeline. If anybody on this forum is good at program coding, maybe they would be interested in adding an EDIUS XML export function to this software. The source code is here: https://github.com/arikrupnik/ltcsync/releases

It hasn't been officially announces as being release for 9.5, but it has been shown to be in the works. I can't speak as to how it will work exactly, just that timecode syncing and waveform syncing are in the works. As was outlined in this thread:
