I think only standard frame rates should be taken into
consideration by Cinelerra-GG, otherwise what is a standard for?<br>
If an User uses a no standard frame rate She/He may have problem
to play it somewhere.<br>
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?<br>
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.<br>
What I know Cinelerra-GG may work with any source frame rate but
the Project Format should be conformed to standards.<br>
The check on the frame rate that Cinelerra-GG performs are just
for that.<br>
Sorry if I think so.<br>
<br>
I would like to know by Pierre, Sam, RafaMar and other Professionl
Video Editor what they think about it.<br>
<br>
Thanks!<br>

(The proxies are 2 because in the timeline I had created a clip and

the previous edit.)
Created a proxy in mov.mov (1/2) ==> OK
Done various editing with proxy/original ==> OK
Deleted the proxy ==> OK
