Recoder - Batch transcode family videos to DNxHD for smooth Davinci Resolve editing (jeena.github.io)

I used to edit family videos in Kdenlive without a problem — it handled footage from all our devices without complaining. But then I switched to DaVinci Resolve, things got difficult. My Sony Alpha 7C, my Galaxy S24, and my wife's iPhone all produced files that Resolve couldn’t handle without transcoding.

Every time I wanted to edit, I had to hunt down the right ffmpeg settings and manually run them on each video — a frustrating and repetitive task.

My typical workflow is simple: I create one folder per event on an external HDD and drop in videos from all our cameras. A script renames the files based on the date and time so I can easily sort them. But for Resolve, everything has to be transcoded to DNxHD — which only supports resolutions like 1920×1080 and 1280×720.

That also meant vertical videos couldn’t work. So now, I rotate them during transcoding to preserve resolution and rotate them back in Resolve during editing.

I built Recoder to automate this annoying step — so I could spend more time editing memories and less time fiddling with command-line tools.

Welcome! This community is focused on sharing video editing tips, tricks, best practices, and software

Some quick rules:

No trolling/grieving/being a jerk (This is subjective, but we should all be adults here)
Don't simply state that something is better in one way or another. Back it up, ideally with sources and video
Don't make a post in an attempt to make a particular program seem superior. Most of the time it's very application specific use case that makes things faster/better
Upload a text tutorial along with a video explanation if that is possible. Some videos are great, but text can be followed simply.
Do not attempt to shame someone for using other software (see rule 1)
Do not bring up how Resolve is better in a lot of aspects. We know that, and understand that. However, in many use cases Resolve simply will not run or compile.

With all of that being said - welcome to the Linux Video Editing community! The goal here is to help each other with tips, tricks, suggestions, and advice.

In my (limited) experience, different software works better for different styles of projects. Here's my personal list of software that I use for various projects which can all be easily installed from most (all?) package managers:

Kdenlive
ShotCut
Olive

Kdenlive is fantastic for quick edits, though it can do a lot more (beyond the quick edits it is clunky imo). ShotCut can do cool things like motion tractking easily. Olive is fantastic for subtitles, but I absolutely would not recommend it for anything with audio.
