Version 1.3.7 is available

[Botond Kósa]

A new upgrade is available, giving more manual control over series approximation. In previous versions it operated in a rather conservative way that sometimes caused a large number of skippable iterations to be computed, e.g. at Dinkydau's Candy location (http://dinkydauset.deviantart.com/art/Candy-417789017). Now the default SA operation is more aggressive, skipping more iterations. In case this causes visible artifacts, SA can be manually made more conservative by raising the value of OOM diff between terms under Computation.

Botond, will you add palette presets that I fixed?

+I can't understand how works this... deflate...

Yes, they will be included in the next release.

+I can't understand how works this... deflate...

Deflate is the name of the lossless compression algorithm used in zip and png files (http://en.wikipedia.org/wiki/DEFLATE). You really don't need to understand the algorithm itself, just use a public library available for your programming language. If you have trouble finding one, I can write a small tool that converts compressed .mmit files to uncompressed .mmi

Where I can get library? Where I can download it for delphi?

I have no experience with Delphi, but http://lmgtfy.com/?q=deflate+delphi

Botond, can you add .png rendering? I can render 15360x8640 images and make movie after.

Yes, check out version 1.3.8

Yes, check out version 1.3.8

Wow! Thank you so much! Palettes and .png are really useful for me.

Oh, how to encode this sequence:
ffmpeg -r 60 -y -i "E:\Video\okay.mma.frame(%04d)of1800.png" -vcodec libx264 -s:v 640x480 -b:v 1250K "E:\Okay.mp4"

Even ffmpeg can't encode this sequence. If you can, change name of like 'Frame_%04d' or 'okay.mma.frame.%04d.png'.

Even ffmpeg can't encode this sequence. If you can, change name of like 'Frame_%04d' or 'okay.mma.frame.%04d.png'.

You could try it without parentheses, like
ffmpeg -r 60 -y -i "E:\Video\okay.mma.frame%04dof1800.png" -vcodec libx264 -s:v 640x480 -b:v 1250K "E:\Okay.mp4"

Parentheses are legal characters in a filename.

So, how to import sequence to file? I tried Adobe AE, Adobe Premiere, Sony Vegas, VirtualDub and even ffmpeg don't see sequence!

[Botond Kósa]

I found in ffmpeg's documentation that you also have to specify the starting number of the sequence if it is other than 0. MM saves the pngs starting from 1, so you should call ffmpeg like this:

ffmpeg -r 60 -y -start_number 1 -i "E:\Video\okay.mma.frame%04dof1800.png" -vcodec libx264 -s:v 640x480 -b:v 1250K "E:\Okay.mp4"

[Botond Kósa]

It also states that if you want to encode all pngs in the directory in the ascending order of their file names, it is enough to set -pattern_type glob and you don't have to deal with numbering at all:

ffmpeg -r 60 -y -pattern_type glob -i "E:\Video\*.png" -vcodec libx264 -s:v 640x480 -b:v 1250K "E:\Okay.mp4"

*.png -> function is not implemented. ?

[quaz0r]

this is a somewhat generic example of one way to run encodes, playing back a sequence of (scaled) images to a fifo using mpv on one term, and running x264 on that fifo in another term, and then of course muxing to a container when its finished.

mkfifo foo.y4m
nice -n +19 mpv -vf scale=640:480 mf://animationdir/*.png -o foo.y4m --no-sub --no-audio --oautofps --oneverdrop
nice -n +19 x264 --opencl --videoformat ntsc --no-fast-pskip --no-dct-decimate --sar 1:1 --fps 60 --crf 16 -b 8 --b-adapt 2 -r 8 --rc-lookahead 80 --aq-mode 1 --aq-strength 0.5 --psy-rd 1.0:0.2 --deadzone-inter 6 --deadzone-intra 6 --deblock -2:-2 --ipratio 1.1 --pbratio 1.1 --qcomp 0.8 -A all --direct auto --me tesa --merange 24 -m 11 -t 2 -o foo.h264 foo.y4m
mkvmerge -o foo.mkv --default-duration 0:60fps foo.h264 foo.ogg

...oops, didnt see your "E:\videos" or whatever.  i saw an ffmpeg command line and assumed lunix
