Thank you! That fixed it. I used the following code: profile = new Mlt::Profile(profileName); producer = new Mlt::Producer(*profile, filePath.toUtf8().constData()); if(!profileName) profile->from_producer(*producer);
The documentation says that I should need to re-open the file, but it doesn't seem to be the case with this. The fps are corrected after I call from_producer. I am using avformat as the producer. So, I'm not sure if there is a mistake there or I should really do it as it could not work with other files? Kind regards, João Gouveia.
