Guys, I want to share a tool with you for proxy with Shotcut. I am working almost exclusively in Shotcut on Linux for my videos since the beginning of this year, and the proxy functionality was something I needed.
So I created this utility I use with all my shotcut projects, which is an interface around ffmpeg, avvailable here, for free, open source too: front4ffmpeg
I start it and go directly to “MLT Proxy” tab, then load my .mlt project file from Shotcut. From the list of clips I can then render proxy files (best use the “same res, but LQ” setting because some filters produce different outcome if clip resolution changes). If you need, you can alternatively import clips from a folder instead from a mlt file.
Then you can use mouse right click popup menu to switch between Hi resolution and Low resolution version sof your clips. So for editting you do everything on low-res clips, then you close your project, in my tool switch all clips to hi-res versions, reopen in shotcut and render.
Imade another post on this forum where I also mentioned this tool:
I keep developing this so it becomes more and more functional in the context of working with Shotcut.
It is open source and in Free Pascal so can be compiled for every platform supported by Shotcut. I could even turn it into a plugin for bundling, could be .dll/.so/.dynlib if needed, so if anyone from Shotcut team wants I can offer this as a contribution, but if not, just please use it until native proxy lands in Shotcut.
