ST 12-3:2016 - SMPTE Standard - Time Code for High Frame Rate Signals and Formatting in the Ancillary Data Space
Abstract:This standard specifies time code formats with the frame counts 72, 96, 100 and 120 and the frame count 120 with drop-frame compensation. This standard also specifies a transmission format for conveyance of the time code and frame count in the ancillary data space of serial digital interfaces.
but try to get also all pdfs from
while you can.. downloading pdfs from tbis site seems to fail me probably due to my location (may be i have them on my main machine, but my machine is 1700km away and offline)
I think only standard frame rates should be taken into
consideration by Cinelerra-GG, otherwise what is a standard for?
If an User uses a no standard frame rate She/He may have problem
to play it somewhere.
If You, like me, think that Cinelerra-GG is a professional program
(I would say mostly Prosumer) only the standard frame rate should
be there to avoid future/next problem with users (and broadcast).
And could it happen for Video/Audio sync?
IMHO, all of you can make a screencast with screen recorder at any
(?) frame rate you want but when you use a NLE the Format Project
should use the standard frame rates.
What I know Cinelerra-GG may work with any source frame rate but
the Project Format should be conformed to standards.
The check on the frame rate that Cinelerra-GG performs are just
for that.
Sorry if I think so.
I would like to know by Pierre, Sam, RafaMar and other Professionl
Video Editor what they think about it.
Thanks!

cool! Did you tried to import resulted files back into Cingg and try to proxy them?)
Rendered again at 144 fps ==> OK; closed CinGG; start CinGG ; load the

Proxy a 1/2 default (mpeg) ==> error:

(The proxies are 2 because in the timeline I had created a clip and
then brought it back into the timeline as a nested clip, appended to
the previous edit.)
Created a proxy in mov.mov (1/2) ==> OK
Done various editing with proxy/original ==> OK
Deleted the proxy ==> OK
