poisondeathray, thanx for all of your advices 
Firesledge, wow nice script, but when i change the lmin option the result become unreasonable
the script don't give me a 1280x720 resolution
but it works fine with the default
question, why do you put the SD resolution 852x480 not 848x480 ?

thanx for answering my questions
another last question, when we say 480 we mean 848x480 or 640x480 ?
because i must know the resolution if i wanted to do downscale-upscale test
and if i maked sure that it was upscaled from this resolution, i will encode it in this resolution because i will not have more quality than it (correct me if im wrong)

another question
if i saw an anime source and it was real HD 720
thats mean that the studio provided in HD, right ?
what if it was upscaled from 480, is that mean that the studio didn't made this anime in HD 720 ?

hi
how can i know if my source is a real HD or just an upscale from 480p ?
im encoding anime series, but some of it not real HD for sure
so how can i know that ?

H.264/AVC / Re: resolution and ref,bframes ???
« on: January 29, 2012, 11:09:35 AM »Quote
Seems like you are trying to calculate the maximum allowed references for a level,... if so this thread might be interesting,....
yeah thats right
Quote
to my knowledge, the specification has no restriction on the number of bframes.
this applies to both the levels and the standard overall.
x264 simply has an arbitrary maximum at 16.
the only primary restriction on bframes is the ability to have them or not, which is specified by the profile.
so i can use more than 9
actually i saw many using 16 bframes in there encodes but i was not sure if it is right to do that
thanx

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 / Re: DeDup filter ??
« on: January 09, 2012, 02:25:11 PM »Dedup will drop all frames that are below the threshold up to the maximum drop count. Dedup does not know what makes the output "bad".
As for the file size, what are you comparing it with? The same input with the same options (excluding the TC fie)? If so, I wonder what settings you're using.
im comparing between 2 outputs from the same input file and the same settings:
1st ouput without input the timecodes file to the encoder
2nd output with input the timecodes (--tcfile-in "path")
and the 1st output size less than the 2nd

i meant :"dedup will not drop frames that makes the output video bad, right?"
because i tried this way before http://minitheatre.org/forum/13-guides/75297-how-to-convert-cfr-to-vfr.html
but it wasn't good
but dedup 2-passes work fine
another questing : the file size didn't reduce when i use this command --tcfile-in "path" ,why ?
i used the timecodes v2 that dedup took out
(and thank you about the last topic , i removed it mistakenly)

« 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:
2nd pass:
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 <

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
that was the first pass
and the second pass
here
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
and the second will be like this
there is nothing wrong if i do it like this, right ??
