You have my empathy for this kind of sentiment. Personally this seems somewhat rare in practice. That being said I'm curious if anyone has anecdotes they can share about these kinds of things?

If you're willing, could you try using AdaptiveDetector? It should have better defaults for handling fast camera movements a bit better. The threshold values themselves can be tuned if you generate a statsfile and plot the result, but

Awesome to see this! I actually wrote PySceneDetect, was great to see it getting some use here. Would you be willing to share what parameters you were using? I'm curious why the accuracy was so low. PySceneDetect only uses basic heu

Are there keyboard controls? Someone I was just playing with seemed to always lock on each "note" or "half note" exactly, wasn't sure how they were doing that.

Thanks for giving PySceneDetect a try. Can you share what you're using as the command line arguments? For detecting fades-to-black, you want to make sure that you're using the detect-threshold command (not detect-content). For e

This is still relevant I think :) What you mentioned is very similar to an edit decision list (EDL [1]), of which I only learned recently. I had a feature request [2] to support EDL as an ouptut format, and upon further investigation, it

This is indeed correct, I'm just using HSV instead of YUV, but the primary source of information is the luma/brightness component (although currently all 3 of the HSV components are averaged, so perhaps a better weighting may impr

Hi Hamuko; Would you be able to share a small sub-set of the episode, in particular the area where you're unable to detect the starting segment? (If not, no worries!) There's a few issues with PySceneDetect currently that may lea

This is definitely a good idea, and something that I'm most open to considering for a future release of PySceneDetect. Admittedly the current version does not handle single-frame "upsets" like this, but this does seem like a

Surprisingly, this uses a fairly simple heuristic to accomplish just that (HSV deltas). I'm the author of the program, and it actually works pretty well with Pulp Fiction as a whole. The one area where PySceneDetect does struggle with

That's an interesting point, although you have to remember airplane mode turns off all radios on the device, not only the Wi-Fi. They probably use it as a "fool-proof" method to prevent any unintentional interference with

It would be cool if you could generalize this for anything (e.g. ls ls -al). That being said, I wonder if there's any actual command-line utilities that actually use a similar syntax to perform something useful.
