Colour mod and special effects filters !

[delacroixp]

It's my first month here and I didn't find a neat fit under Mpeg-4 AVC... so I thought I would head over to the starting blocks... and join the 'new recruits'...

I'm encoding 'Band of Brothers (http://forum.doom9.org/showpost.php?p=977686&postcount=1684)' into H264 with AutoMKV and the MKV container...
I did a test sample at Q18 and compared to the original (see post), the colours seamed lacklustre and bleached... buzzqw (http://forum.doom9.org/showpost.php?p=978227&postcount=1700) did start to mention something about something else (see post) and he's been so busy trying to reduce the already complicated filter system of AutoMKV that I thought it wise and prudent to trouble him no further...

Are there filters that can be used, not only to enhance 'colour saturation'... but radically alter the colour makeup and even add-in special effects...
The black and white movie Casablanca (http://en.wikipedia.org/wiki/Casablanca_(film)) was colourized at some stage and while I'm no movie-maker/producer... it would be nice to add-value to some of these movies instead of slavishly reproducing already-perfect movies into a lesser quality with H264 and the like... ultimately just leaching, I wont say pirating, from the movie industry at large...

Any thoughts...

I didn't realise this was so difficult... perhaps everyone's on Easter Holiday...

Happy Easter !

of course, any changes you make will be to the detriment to the original intent of the film...

however, if a straight encode is giving you different colours to the original, you might want to have a look at the playback chain - usually it's just a matter of tweaking the nvidia overlay settings. the actual colour inside the mkv should not be any different (apart from noise of course).

Quite right... and I suppose H264 is also using the same 4:2:0 chroma subsampling though I gather it can support 4:4:4 (http://en.wikipedia.org/wiki/Chroma_subsampling) if necessary.

Either way there's no point in boosting colour that isn't even there in the original or encoding below 18-CQ-CRF... so your judgement on playback sounds good...

:thanks: much
