Zones in x264vfw?

[movmasty]

Anyone thinks to implement this feature in x264 like in xvid?

Or it is not useful in h264?

[Dark Shikari]

x264 has supported zones for years. What's the problem?

[movmasty]

i mean the vfw interface, if there are zones...i dont find them :helpful:

[movmasty]

another thing, i need a tool to analize encoded movies, number of I P and B frame, used quantizers ecc...

[TheRyuu]

cli does all of the above. lrn2usecli?

Edit: I don't mean analyze the movie, I mean tell you the number of i/p/b/quants/etc used.
if you want to analyze it you can use avinaptic or something like that.

[LoRd_MuldeR]

movmasty, if you used VirtualDub + VFW before, you may want to give Avidemux a try:

There is support for x264 zones in the Avidemux 2.5 series now...

thanks for your reply,
it is not matter of learning the cli, the fact is that i like to use avi for now :o

and i dont really need to analyze the movies, just know the above infos
any link to any tool?

[Dark Shikari]

any link to any tool?x264 prints it when you're done encoding--what more do you want?

im just using it :)

but is the 2.4 version :(

downloaded today, should dl the 2.5 uhu?

two things on it,
the outputted avis show a black screen loaded in vdub, but plays well in all players,
correct infos on the movie and keyframes are reported, i can browse by kf but see only a blank screen

and if i begin the encoding from frame 0 puts a random frame at the begin of the movie

[movmasty]

Then don't use H.264, because H.264 is inherently incompatible with AVI.and not avi is inherently incompatible with video editing....
i am letterally terrorized to see the world filled with not edit friendly formats, and to be not able to use all the tools im used to, later maybe, let it be a progressive change.

x264 prints it when you're done encoding--what more do you want? ok, i just want to be able to look into old movies too,
doest exist a so simple tool?

[Dark Shikari]

Are you insane? Do you even know what an editing format is?

[movmasty]

Wait, you want to use an interframe video format with B-frames as an editing format? Are you insane? Do you even know what an editing format is?maybe container would been a more exact term,
the fact is that i like very much to put my dirty hands on every movie that comes around me,
also small modifications on old encodings, audio, keyframes cuts ecc
or just the fact that i cant open new formats in Vdub...

i know what an editing format is, and to reencode a movie i always use intermediate formats like huffyuv,
and if i am not wrong h264 has a losseless mode too,
then b frames are not a mandatory feature...

i would not like to see the avi era finish abruptly like the South confederation :o

[movmasty]

just some difficulty to browse folders but its ok.

[LoRd_MuldeR]

That's a problem on VDub's side. More specifically this is the result of the fact that VDub depends on VfW decoders for reading the input source file.

Two suggestions:
1. Save the video in some "lossless" format, such as HuffYUV or FFv1 in Avidemux (You will still need the suitable VfW decoder to open that in VDub)
2. Try to open your file in VDub via Avisynth. You could try the FFVideoSource() (http://forum.doom9.org/showthread.php?t=127037) filter for that, which should handle any file created by Avidemux.

[movmasty]

c'mon, you know what i meant, you can do anything at the avi container, not the same with others,
lets just wait sometime

there is a 3d, open using 'Direct show input format' ;)

i opened others h264 avi in the past thought

-
using 'Direct show input format' i see the movie, but not keyframes,
with vfw have keyframes but not the image :o

maybe there is some import filter to write.

[movmasty]

There is support for x264 zones in the Avidemux 2.5 series now...

But if, like you said in another 3d, the CRF encoding is based on motion, and not just on bitrate, zones are not needed anymore

[LoRd_MuldeR]

But if, like you said in another 3d, the CRF encoding is based on motion, and not just on bitrate, zones are not needed anymore

Uhm? There is nothing that prevents you from assigning a "bitrate factor" or a "constant quantizer" to specific zone within a CRF-based encode :confused:

Simple example: Encode the movie at CRF=22, but assign a bitrate factor of 25% to the ending credits, as quality doesn't matter there...

False.
For example Avidemux can edit MP4 files...
AVI is just soooo obsolete... you cant put h.264 in avi... is just like putting a Ferrari F1 engine in a Ford model T.
Maybe you could do that and start the engine... but you cant expect the car to be safe and run at 350k/h...

[Selur]

AVI is just soooo obsolete... you cant put h.264 in avi...
I too agree that it's sad that not enough video editing tools support .mp4 and .mkv, but isn't it (nearly?) the same 'hack' that's used for Xvid&Co inside avi? (so the whole 'bashing' people who use h.264 inside .avi seems a bit much, at least the Xvid&Co users that se .avi as a container should get the same 'heat'. ;))

Cu Selur

[Dark Shikari]

I too agree that it's sad that not enough video editing tools support .mp4 and .mkv, but isn't it (nearly?) the same 'hack' that's used for Xvid&Co inside avi? MPEG-4 ASP has Packed Bitstream, which is a hack nonetheless, but at least a widely-supported one.

[movmasty]

Please, where do i find a guide for x264vfw or at least for x264??

ok, but i used zone to compress more the fast parts

[Sharktooth]

:search:

[movmasty]

:search:
i did, and found one here a more suitable guide, but incomplete too

http://mewiki.project357.com/wiki/X264_Settings

then i was looking for the default flat and jvt matrices too, to judge the custom,
i even pvt message you asking where to find, fortunately your box was full....

anyway to ask here is a form of search, usually i ask when i dont find....eh, paisà....

[movmasty]

You are right, now we need a similar hack for h264 too! :D


i agree with the critics to avi, just we need sometime that the rearguard joins the generals....

Is it really that hard to search for threads with "custom matrices" in the titel in this subforum when you want information about them?

[movmasty]

Is it really that hard to search for threads with "custom matrices" in the titel in this subforum when you want information about them?
And in fact i found a whole lot of custom matrices, but i was looking for the default ones :o

another problem is that im not able to use the AND operator in the search here, so using the words custom matrices will find thousands of posts with custom OR matrices...
i could ask you how to do, but then someone will reply to do a search...

usually when i need something i first do a search on google and here, and if i dont find i ask in some 3d if anyone knows, dont think is a bad think to ask for help.

The default is an AND search because searching for custom OR matricies in titles only in the AVC forum returns 322 threads, up from 4

[LoRd_MuldeR]

And in fact i found a whole lot of custom matrices, but i was looking for the default ones :o

The default matrix is the "flat" matrix. That is: All entries filled with 16's ;)

Furthermore the only info about "custom" matrices for x264 you need to know is that you normally don't need them.

(That's because the "psy" optimizations in x264 basically make custom quant matrices obsolete)

we who? ... and above all things... WHY?
VFW was not meant to handle h.264... and anyways, AVI is useless.

[movmasty]

hacks are made for this, DVD are not meant to be backupped...

[Sharktooth]

you have a distorted idea on what is an "hack".
in this case, what you call an hack, is a way to FORCE something to handle something else... and that ends up in a complete mess screwing up everything.
