Description Evert Vorster 2016-09-14 12:13:53 UTC
If I have a piece of footage that I want to both stabilize and slow down, I can do it today by slowing down the footage first, then rendering the .mlt file, and then running the stabilizing clip job on it. 

What is stopping us from running a clip job on an .mlt file?

Conceptually I don't see anything preventing nested .mlt files, it would be almost like loading a saved project as a clip, no?



Reproducible: Always

Evert, as there recently have other reports touching mlt and proxies: is this report still valid or stale? Or am I on the wrong track here and this handling of MLT files in clip jobs is still open?
Comment 2 Evert Vorster 2016-10-08 23:06:42 UTC
Not stale at all. 

Apply speed clip job, get .mlt file in the Project Bin. 
Try to stabilize the .mlt file. 

I get an error message: "No valid clip to process"
Why can't we stabilize .mlt files?

Hi Evert, thanky for your reply. It helps me to better understand the issue.

My (limited) understanding is that vid.stab uses ffmpeg for decoding the unstabilized video, and then ffmpeg again for encoding the stabilized result video. But ffmpeg can't handle MLT files as it doesn't understand them. MLT sits on top of ffmpeg, but ffmpeg doesn't know about MLT.

One way might be to first transcode from MLT to some video format that vid.stab and ffmpeg can reread later when running the stabilization.
Comment 4 Wegwerf 2016-10-09 09:15:24 UTC
Erm, but as vid.stab generates a MLT output file, at least vid.stab is run from inside MLT it seems...
Comment 5 Evert Vorster 2016-10-09 12:22:28 UTC
It would be a nice shortcut on .mlt clips only to be able to render the .mlt clip at it's input resolution and quality settings, and add the resulting clip into the Project.

Hi Evert about 4,5 years later: can you please check if this feature request is still relevant (especially after the job manager rewrite)?
