Re: [Cin] Proxy error (optimal settings)

[Phyllis Smith]

In the Resources window comment field the addition of fps and codec have
been added.  This has been checked into GIT and is in the latest ubuntu16
build in the usual place.

In a old post/thread/issue (I don't remember) I had written that would be

OK, will not touch it.  I will change the manual to say what to look at for
check_frame_rate error.

I did not know you can do this -- I kept changing via Set Format menu.
BTW:  I could not get either the 61fps or the 119.88fps files to proxy even
with MOV.  Is that correct?

I do not think this would be difficult to do in the code BUT to add this to
the comment field, you have to actually open the file to obtain that
information.  Which means that when you load a lot of files, it is going to
slow down.

Had to laugh at this video.  Gene Wilder was in some funny movies -- I

Same here.



Usually, the professional mode is ...
1) to convert the source video with a external program, like Eyeframe 
(unfortunately only for Windows program) or ffmpeg, to a friendy fps 
(and change GOP, GroupOfPictures).
2) "to convert" the fps inside Cinelerra-gg, like I have done with 
your 61 fps video: in Resources->Media, select the video, RMB on that 
video, choose "Info" option and change video's framerate.

I agree with you Igor. If I had seen that it wasn't 120 FPS but 119.88 
FPS, then I would have come to the cause of the problem myself.

You're right, it's actually 119.88 FPS. My camera shows me 120 FPS, 
apparently it rounds up automatically.

Well I am very surprised!  Streamable took my 120fps and made it 61fps !!!
So I was continuously testing the original file that I had uploaded and you
were testing the file that was downloaded and made into 61.

So now I downloaded the multilated 120fps.mp4 which was 61fps and it failed.

Thanks to both of you as this was driving GG crazy all day long.  He says
it is up to the codec as to whether or not it accepts a certain frame rate
for encoding.  And we just discovered yesterday, no matter what you Set
Format fps to, the proxy uses the original media fps always.

Sam, please check your large original camera files to see what its original
fps is -- it must not really be 120fps or it should have worked?

Do either of you have a suggestion for a workaround in Proxy to be able to
use a different fps?  Something like "Override frame rate ? "  gg/Phyllis

Igor, you're absolutely right. The video is rendered down to 61 FPS. 
Well observed!

The project format is set to 25 FPS.

1) I downloaded the ot7nz.mp4 file from "streamable.com" and I checked

1280x720. So, I think, streamable changes your video compression 
format even if I saw Sam's video with others parameters for the same 
video. Booh!
2) However I loaded ot7nz.mp4 video in Cinelerra-gg and I have got the

works.


Could you give me the original video file 120fps.mp4 uploading it to

@Sam: your video source was to 120 fps but what is the Project's
