| Feb 26, 2013 at 2:49 | comment | added | Amir T | Yeah, I've tried two versions, the ubuntu default from apt-get and the static build. | |
| Feb 26, 2013 at 1:21 | comment | added | Chris James Champeau | Well the FFmpeg I am using is a MAC version versus your Linus version not sure but my guess is that there must be a bug with your FFMPEG?? have you tried removing it and reinstalling the latest version? | |
| Feb 25, 2013 at 21:37 | comment | added | Amir T | @ChrisJamesChampeau thanks for the suggestion - I tried the command you listed using the static build of ffmpeg I get slide 2 at 12s and 3 at 17s: dl.dropbox.com/u/64693533/sync_test/sync_test1.cjc.mp4 | |

Adding -r 15 is the same as omitting it because ffmpeg will inherit the input frame rate by default, and the resulting output files, with or without -r 15 are exactly the same with ffmpeg from git head (version N-50285-gad89952). If it is working for you using an older ffmpeg version this could be a regression and should be reported to the FFmpeg bug tracker.

| Feb 20, 2013 at 3:08 | comment | added | Amir T | I added an example source file. The sync issue is very noticeable. It seems to me like a bunch of frames are elided for various formats. | |
| Feb 20, 2013 at 2:38 | comment | added | Chris James Champeau | Read my updated answer...I think it is an issue of FPS | |

| Feb 20, 2013 at 2:36 | comment | added | Amir T | The input format is ogv which is what gtk-recordmydesktop outputs. I'm trying to get to anything other than ogv (flv, etc). | |
| Feb 20, 2013 at 1:20 | comment | added | llogan | The original file is Theora video and Vorbis audio in ogv container. Amir T is not re-encoding to this format, as far as I know, but when he attempts to re-encode the original with either ffmpeg or YouTube the sync problem manifests. | |
