Stumbled on a blog post today about this topic, which is worth the read IMHO - "Why I moved away from FOSS as my main toolset". The author, whom I first met when he was a student in a LEVA Level 1 and/or 2 class I was teaching the better part of 10 years ago, raises some valid points about leveraging FOSS in DME workflows; training, support and documenting FOSS tools being the points I agree with. To that end, keep your eyes & ears open for news about professional training & support for FOSS solutions related to DME.

With that said, I'm going to make a few comments and pose a few questions to the community based on the above post, so if you haven't read it...the rest of this post is probably moot.

Lossless trimming is the ability to trim, cut or extract segments of audio & video without re-encoding the original multimedia streams, maintaining both the original frames/samples and their related metadata. It is a process as old as digital video itself, and one that can be extremely helpful when dealing with hundreds or thousands of hours of digital video evidence for a case.

Reduce file size, reduce duration and maintain the original frames & quality. Bonus, the process is even faster than traditional editing, as you don't have to wait for the video to be re-encoded!

Spatial vs. Temporal Compression

Spatial (Intraframe) compression is applied to each video frame independently, treating each frame as a stand-alone image. This is the type of compression leveraged by high-end video production facilities as it provides superior picture quality and efficiencies in the editing process. Every frame is a key frame.
