Preview cannot Preview .flv (& probably some other "ordinary" video extensions; .mkv) (at least on Win7) This is actually (probably most related to) the setting of: (Windows) Folder Options | View -> Always show icons, never thumbnails If checked, thumbails will not display (in DC). I...

Drives (& the graphic aside), mixing of size units. both Size & Free Space "mix" GB & TB so if you're reading 58.7 GB 1.93 TB it's kind of meaningless, as ones mind doesn't read both the number & the Unit, they only see the number so they say 58 > 1 which is entirely incorr...

Video mode -> Video Tags


Oddly, does not have Length?


Likewise (I suppose it is in the Results list), while you can display (MediaInfo) data on a file, & while you do use mediainfo.exe, it does not display Length nor is Length shown on the timeline in the Preview window.

Image Mode / Video Mode - identify Exact Matches Image Mode (Video Mode) when any mode other then Exact Match is selected you should specifically identify "exact matches" looking down a list of thumbs, you may see sets of files that seem to have all the same "close" match, but yo...

Search filters If All file extensions is checked the Include / Exclude filters do not /appear/ (do not show) Not seeing them, & never having had the occasion to want a specific include/exclude filter, sends one scurrying around trying to find, "where is that option, it has to be there"...

V+A must be using different algorithm, ffmpeg method which is much slower (then V only or A only) need it be that way? V (or A) is 0:05 (5 seconds) V+A is 4:01 (4 minutes) with V+A, the same algorithm, twice (separately, not in parallel, at that) i don't really understand just what that different ha...

No overflow indicator. So I'm running a scan & I can't understand why it's showing files it should not be showing? And I check this & I check the other &... Finally I say, "let me add the directory, again". And it then showed, twice!? And I'm like what? I had the same sets of f...

ffmpeg -i input.mp4 -map 0 -c copy -f streamhash -hash md5 - vs ffmpeg -i INPUT -f streamhash out.sha256 So it seems it's the -c copy that makes the difference in speed? With -c copy, ~25000 frames at a time . Without it, ~350 frames at a time . ("At a time". At a time I don't know what? ...

Neat. I'll have to play with that. I'll assume you are using streamhash rather then stream copy - even for V+A (as it is worlds faster). (And you could always hash the separate V & A hashes that streamhash gives to "generate" a V+A hash. And while that would be different from the hash ...

Ah, so this: How to md5 the video track (only) in ffmpeg.

Never knew such a thing (option in ffmpeg) existed.
