Вопросы по VirtualDub.

Silent

Если кто-нибудь оцифровывал с помощью данной проги, подскажите. Когда оцофровываешь с помощью divx4.12 там есть варианты 1-pass и 2-pass причем 2-pass требует файл divx.log.
1) Чем отличаются варианты оцифровки?
2) Где взять файл divx.log?
3) У меня на компе есть divx5.0.2 почему VirtDub видит только 4.12?

вот полезная статейка divx faq
или в инете

В ссылке http://ixbt.mexmat.ru/www.ixbt.com/digimage/divx-specificity.shtml.htm - ixbt.mexmat.ru не резолвится.

pnlc

дык это в фдс. надо VPN включать.

oleg701

IP скажи, и все пойдет.

pnlc

10.1.64.24
но через IP у меня не идет

oleg701

Значит IP не такой. Других вариантов практически нет.
У меня тоже этот адрес не резолвится

pnlc

стопудов такой IP

oleg701

Я лично слабо представляю себе как может идти по адресу, но не идти по IP, особенно если учесть что IP - более предпочтительное представление, просто его труднее запомнить. А ixbt.mexmat.ru у тебя пингуется?

ася есть. могу скинуть. а ты здесь расшаришь.
1038

oleg701

А на каком серваке ася?
У меня только icq.local, там сейчас 1038 в оффлайне

pnlc

на серваке ICE. вроде это он и есть.

Filan

Так какой IP: 10.1.63.24 или 10.1.64.24?!
10.1.64.24 - вообще молчит, а на 10.1.63.24 стоит apache, но видимо с виртуальными хостами и по умолчанию стоит хост не ixbt.mexmat.ru.
P.S. Меня радует фраза: "Hm... Try another link What do you want to find here?" при попытке зайти на http://10.1.63.24 .

pnlc

ага. ошибка вышла.
а по той ссылке что я дал выше тоже не заходит?

Народ! Это все конечно очень интересно, то что вы тут написали, но маленько не по теме.
Может кто-нибудь ответит по-существу вопроса?

C английским проблем нет ?
тады читай, хотя лучше конечно в инете найти:
For those who are intrested on encoding information for quake movies using the DIVX codec, the following will help you get the best quality and the lowest possible file size for your Quake movie.
Below I will explain each component of the DivX codec encoder panel and it basic functionality. PLEASE NOTE: You do not see this panel nor is it accessible during DivX playback. This encoder panel is ONLY seen when you encode a DivX video with any third party applications (VirtualDub, FlaskMPEG, Premiere, Media Cleaner, etc.)
GENERAL PARAMETERS
-pass
In this mode, the encoder will aim at making the average bitrate of movie close to specified value, retaining more data for low-motion scenes and losing more information in fast-motion scenes.
1-pass quality-based mode
In this mode, all frames receive the same amount of compression, without regard to their complexity. While it is not the best choice for making archives, it is a good idea to use this mode when preparing content for future editing. It guarantees the preservation of quality in all frames.
2-pass variable bitrate mode explained
In this mode, the encoder will try to make the subjective quality of the stream constant, and simultaneously make the complete stream size close to the number you specified. If you want to encode a 2-hour show that it fits on a 650 Mb CD, use this option.
Operating in this mode is most complicated, because it requires the source to be processed twice. 2-pass encoding is independent from any application you may use for encoding. It can be used with any program. However, it needs to use an external file on your hard disk to temporarily store encoding data.
2-pass, first pass
First open the encoder configuration dialog box (in your encoding application like virtualdub choose "video | compression" highlight "DivX 4.0x" and press the configure button). Then go to the "general parameter" section use the "Variable bitrate mode" pull down menu and choose "2-pass, first pass." During this pass the encoder ONLY analyzes the source and then creates a log file with information about the frames. The "Log file" field in encoder configuration dialog must point to the place where encoder has write permissions (you'll need about 250 kb of disk space for each 1 minute of video. A log file can be tens of MB's). Start 1st pass process. The encoding program will then create an unplayable AVI file and write the log file in the root of your "C" drive.
2-pass, second pass
When it's finished, return to the configuration dialog and select "variable bitrate mode" --> "2-pass, second pass." Start encoding (the source video must be the exact same one!). At this time, the encoder will read the log file that was created in the first pass and writes the real VBR AVI to the root of the "C" drive, or to another location you specified.
It is best to use the same "performance/quality" setting for both passes, but it is not an absolute requirement. Don't use performance/quality mode of "fastest" for either of two passes. You can also use different values for "bitrate" in first and second passes, but if they differ by +50% or -50% the encoder may not achieve the file size you want.
Performance/quality
The settings are: Slowest, Slow, Medium, Fast, and Fastest. These let you decide whether you want the encoding to be done fast or to crunch everything to the smallest possible size. "Fastest" mode is optimized for real-time video capture. This choice is recommended for use with "1-pass quality-based" bitrate mode. "Slowest" mode with "2-pass variable bitrate mode" is good for making video archives. The default value is "slowest".
Output Video Bitstream
It shows the current kilobit/second. You can manually or use the slide bar to input a stream value between 0-6000 kbps when using 1-pass encoding.
Maximum key frame interval
This is the maximum interval between the places to which you can seek in resulting file. The DivX encoder will insert a key frame every time it detects a scene change. However, long intervals between scene changes are possible, and when they occur, the encoder automatically inserts keyframes with specified frequencies. The default value is 300, which corresponds with one keyframe at least every 10 seconds in a 30 fps stream.
Max CPU
This sets the minimum and maximum level at which CPU time used by the encoder, to give some time to other tasks or to reduce processor temperature, for example. By default, it is turned off. If you have a really fast enough processor (700 MHz or faster) turn it on.
Deinterlacing
Video streams captured from TV or VCR in high resolutions usually contain "interlacing" artifacts. For example, maximum allowed height for NTSC is 480 lines at 30 frames/second. However, the actual television signal has a frequency of 60Hz and only 240 visible lines. Thus, captured streams will contain interleaving lines from two subsequent "fields," which have different positions in time.
The good thing about deinterlacing inside the encoder is that it's done almost for free. The most popular video processing applications include deinterlacing filters, but they can eat up to 15-20 percent or more of the time. In contrast, deinterlacing in the encoder takes no more than 1-2 percent of CPU power. The default setting for "Deinterlacing" is "off."
Do not use deinterlacing inside the codec if input stream was resized or otherwise preprocessed in some way. If you want to do complex filtering of interlaced streams, always use external deinterlacing and put deinterlacing filter first in the pipeline.
DECODING PARAMETERS
Post-processing
The post-processing algorithm consists of the deblocking and the deringing filters. Post-processing is a CPU-intensive process, which sometimes takes longer than decoding. You may not want to post-process, especially if you prefer the un-post-processed image, or if your PC is not powerful enough. To cater to users' post-processing preferences, 6 different levels of post-processing have been defined. At the minimum (level 0 no post-processing algorithm is used; at the maximum (level 6 every clever algorithm is tried to enhance the appearance of your frames. The human eye is less sensitive to the chrominance components of the video signal and more sensitive to the luminance components. For this reason, only the luminance plane is processed at lower post-processing levels, while higher levels activate the same algorithms on the chrominance planes. The post-processing algorithms used are activated in the following order: deblocking on luminance planes, deblocking on chrominance planes, deringing.
You can adjust postprocessing level in two ways. Use the slider in the configuration dialog of DivX DirectShow filter (which can be accessed from Windows Media Player window while playing) or in configuration dialog of encoder DLL. Both sliders do the same thing.

Это уже кое-что Попробую разобраться. Спасибо.

Хотя я думал, что может кто-нибудь выскажется по пунктам. Так у меня уйдет меньше времени на прорюхивание Неужели никто оцифровкой не парился?

bonnyboo

вообще то это не оцифровка, оцифровка это нечто другое

spirtus

делал мувики, придет с работы - может напишет.
Могу посоветовать поставить для начала нормальный кодек - DivX Pro 5.0.2 и зарегить его кеймейкером от DAMN:
