x264 image sequence encode to mp4 no ffmpeg plz.

[ioncube]

So have been trying how to feed image files to x264 built that I always use. I don't like syntax of Handbrake & or ffmpeg so plz don't recommend them.
Have searched this forum but guides aarent available for x264 image sequence » movie
Plz help
My code so far...i know the input command needs work

x264.exe --frames 1 --8x8dct --trellis 2 --subme 9 --psy-rd 1.5:0.5 --aq-strength 1.2 --input-res 3456x2304 --deblock -2:-2 -o "D:\Dad.mkv" "d:\Trainers\Dad\*.jpg"

"d:\Trainers\Dad\*.jpg" will probalby not work,...
you probably need to use something like: "d:\Trainers\Dad\%04d.jpg" if your files are named
0001.png to 9999.png

This willnt work either, I thus used AVSscript as follows:

source = ImageSource("c:\ff\%03d.jpg",fps=0.2)
source = source.BilinearResize(1280,720)
source = source.ConvertToRGB()
return source

...& then fed it to x264 like:

x264.exe --input-csp  yuv420p -o "D:\output.mkv" "d:\Program Files\AviSynth 2.5\Examples\input.avs"

But the output mkv is extremely poor, don't know why

[jagabo]

Since you didn't specify a CRF value you got the default, CRF=23. Try specifying a lower CRF.

I've never used the --input-csp argument but your AviSynth script is returning RGB and you are specifying --input-csp yuv420p. I don't know if that would cause problems. Change the ConvertToRGB() to ConvertToYV12() in your script.

I don't know what you're converting but keep in mind that YV12 maintains chroma (colors) at half the resolution of the luma (greyscale). So small colored object (especially text) on colored backgrounds can get very blurry.

[Selur]

Also your color spaces do not match,...
Due to ConvertToRGB(), Avisynth return 4:4:4, but you tell x264 that the input-csp is 4:2:0.
-> with mismatching color spaces output is bound to look strange,..

Thnx for assisting someone who is trying to learn via experimenting. I mended my scriots as follows
x264:

x264.exe --crf 23 -o "D:\crf18.mkv" "d:\Program Files\AviSynth 2.5\Examples\imageseq.avs" 2>&1 | mtee /d/c/t log.txt
pause

avs:

source = ImageSource("c:\ff\%03d.jpg",fps=0.2)
source = source.BilinearResize(1280,720)
source = source.ConvertToYV12()
return source

the output log is:

Now the real problem is when I open the output video file in any player it states the duration of file is 1hr23min? Strange because there are a total of 12 jpg files that am encoding & with a fps=0.2 it means each picture duration is 5sec & we will get a total movie having duration of 12x5=60sec=1min

[Selur]

since x264 outputs "encoded 1001 frames" which @0.2 fps results to 1:23min the problem lies with your avisynth script, which seems to output 1001 frames
Not sure if ImageSource even supports fps < 1,..
-> check your avisynth scrip with Virtual Dub or similiar to see how many frames it returns,..

Respected sir, I am just a chemical engineer who is trying to learn video encode for personal reasons.
Now because I have displayed everything there is no room for error in any script! I have dopne some maths & discovered that

Duration x fps = totalFrames

Now am adding 12 pics & previous posts states that with a fps=0.2 i must get 60sec movie thus

60sec x 0.2frames/sec = 12

Thus we only have to encode 12 frames. Without changing any other script I just changed x264cli & got perfect result:

x264.exe --crf 23 --frames 12 -o "D:\crf18.mkv" "d:\Program Files\AviSynth 2.5\Examples\imageseq.avs" 2>&1 | mtee /d/c/t log.txt

ImageSource() defaults to 1001 frames. You have to specify the start and end frame numbers if you want something different. ImageSource("c:\ff\%03d.jpg", start=0, end=11, fps=0.2)

@jagabo
can you also explain this bit of log:

resize [warning]: converting from bgr24 to yuv420p

[poisondeathray]

can you also explain this bit of log:

resize [warning]: converting from bgr24 to yuv420p

This means you convert from RGB colorspace to Y'CbCr and subsample the chroma to 4:2:0

I have screenshots of resolution 1440x900 which I resize via BilinearResize(1280,720) which gives the above mentioned error. Can you tell me how do I find the colorspace of my picture & get rid of this error

[jagabo]

I've never seen BilinearResize() give that warning but you should be able to avoid it by converting to YV12 before resizing.

You can use Info() anywhere in your script to see information about the video at that point in the script. The information will be written onto the image.
