I'm just beginning to use the MLT/melt command-line tool to edit some pretty simple videos. I found how to join several video clips, how to set a fade transition between the different clips, the only thing I'd need and can't manage is inserting a title at the very beginning of my movies.
I thought of creating a
.png image, then add to the melt arguments (I think I saw one or two examples around here), but it looks like melt doesn't behave as expected.
- It was not accepting my 16-bit
.png. Well, no problem, I used an 8-bit
.pngand it worked.
I can't get the image to be displayed long enough. No matter which
outvalues I set, the image briefly appears and disappears. Here's the command line I'm currently using:
melt title-8.png in=0 out=300 clip-1.mp4 -consumer avformat:... vcodec=.. acodec=...
Mac OS 10.9.1, Melt 0.9.0
Edit : Just tried the same command on a Linux VM, and it seem to work as intended with Melt 0.8.8. Maybe a bug or a new behaviour introduced by the 0.9 version, I'll check that out.
