Hi all,
when export to prores or h264 the created file has variable frame rate.
is it possible to have constant frame rate?
I'm using the latest test version.
thanks

Re: export to prores
Do you mean constant bit rate?
Re: export to prores
No, I mean frame rate.
Media Info detects variable frame rate.
Also when I import the cretated file to a NLE, also the file is detected with variable frame rate.
Thanks

Re: export to prores
Strange. I converted a test movie just recently into both mp4 and prores/mov, and neither shows that issue.In QT Player and media info, they are both shown as straight 24 fps. Which version of DCP-o-matic are you using?

I'm using 2.13.145.
I'll try with a different PC. Maybe it's something on my side.
Attached a screenshot of nedia info.

Re: export to prores
How do you create a 1920/1080 export?
That frame rate display may be a misindication, as often, some tools do not read such things from file headers, but compute them from certain aspects of the file. So, this could be misleading especially for short files.
I will do my tests again, though, with the current test version.

Re: export to prores
I've created by selecting 1.78 container on dcp tab.
I've got same result if using the original dcp container, in my case dci flat
I'll try with a feature and not a test.

Re: export to prores
Alright, it happens here with 2.13.146 on my Mac, too. Both when exporting a 24fps MP4 source file and when exporting a 24 fps DCP. I don't know in how far that is a problem when using the resulting export, as the variation in frame rate is very small (min 23.994 max 24.006). I guess it is only a formal issue. I understand it may cause confusion. Carl may need to look up his latest changes to the export function/ffmpeg.

Hi all
version 2.14.17 exports both, prores and mp4 with constant frame rate.
Tested with trailers 24fps and 25fps. Haven't test a full movie yet.
Thanks
