H.264/AVC / resolution and ref,bframes ???
« on: January 28, 2012, 01:36:33 PM »
hi
i have a question about the good number of bframes and ref to use

im usually calculate the ref like this:
maximum ref = 12288 * 1024 / ( width * height * 1.5)

720p = ref 8
1080p = ref 4

but what about bframes ?
can i figure it like the ref ?
i know that i can't use more than 9 bframes in level 4.1
and i always encode with level 4.1
so i can use them all in any resolution, right ?

Avisynth Usage / DeDup filter ??
« on: January 08, 2012, 12:34:00 PM »
can i use dedup filter for convert cfr to vfr ?

for example i have 23.976 fps source
and i will use the 2-passes of dedup filter
and then i will have variable fps output after muxing the timecodes with the video

like this:
1st pass:

Code: [Select]
DupMC(log="stats.txt")
2nd pass:

Code: [Select]
DeDup(threshold=.1,maxcopies=4,maxdrops=4,dec=true,log="stats.txt",times="timecodes.txt")
that will not take effect on the source, right ?  ???

H.264/AVC / convert to 200 fps ????
« on: January 01, 2012, 01:13:53 PM »
hi

.....
i tried to convert a source that has 23.976 fps to 200 fps !!
for reducing file size, then i had a fast video and this is normal

then i added the timecodes of the raw video to the output video in mkvmerage to correct the length

and everything went fine
but, i noticed some lost in details in the output  ??? ???

so i figure out that this way is wrong (right ??)
and i never saw anyone do that before  ???

but my question is, why did i lost some details in my output video ?
i encoded the video once again with 23.976 fps in the same setting, and i hadn't lost some details from the video

so is there any relation between the frame rate and the quality ??

please i want your answers  :) >sorry about my bad english  :P<

H.264/AVC / ts and vfr question ?
« on: December 13, 2011, 12:24:08 PM »
hi everyone

i want to encode a vfr video from .ts source
i know that i must have a timecodes

i can get it by 2-pass
like this
Code: [Select]
DGDecode_mpeg2source("test.d2v")
trim(8639,26697)+trim(32900,45150)
AnimeIVTC(mode=1,aa=2)
tfm(d2v="test.d2v", output="matches.txt")
tdecimate(mode=4, output="metrics.txt")
that was the first pass
and the second pass
here
Code: [Select]
DGDecode_mpeg2source("test.d2v")
trim(8639,26697)+trim(32900,45150)
AnimeIVTC(mode=1,aa=2)
tfm(d2v="test.d2v", input="matches.txt")
tdecimate(mode=5, hybrid=2, vfrDec=1, input="metrics.txt", tfmIn="matches.txt", mkvOut="mkv-timecodesfile.txt")
my question is- can i encode lossless from the first pass.and encode that lossless with the second pass in x264?  :)
i mean that my first script will be like this
Code: [Select]
DGDecode_mpeg2source("test.d2v")
trim(8639,26697)+trim(32900,45150)
AnimeIVTC(mode=1,aa=2)
tfm(d2v="test.d2v", output="matches.txt")
tdecimate(mode=4, output="metrics.txt")
and the second will be like this
Code: [Select]
ffvideosource("lossless.mp4")
tfm(d2v="test.d2v", input="matches.txt")
tdecimate(mode=5, hybrid=2, vfrDec=1, input="metrics.txt", tfmIn="matches.txt", mkvOut="mkv-timecodesfile.txt")
there is nothing wrong if i do it like this, right ??
