VirtualDub - одна из лучших и популярнейших программ для самой
разнообразной работы с видео - от захвата и обработки до
конвертирования.
VirtualDub - программа для захвата и
обработки видеофайлов. Она умеет читать и писать AVI2 (OpenDML) и
многосегментные AVI-файлы (для преодоления барьера 2 Гб). Имеет
встроенные декодеры MPEG-1 и Motion-JPEG, а также позволяет подключать
иные видео- и аудио-кодеки. Программа поддерживает создание AVI с
дробной частотой кадров, удаление и замену звуковых дорожек, импорт
звука из внешнего источника, удаление любых фрагментов из видеоряда и
склейку видеофайлов. В VirtualDub имеется мощный набор фильтров, таких
как blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate,
brightness/contrast, levels, deinterlace и threshold. Такой набор
неплох даже для графического редактора.
Кроме этого, имеется
возможность написания и подключения своих собственных фильтров.
С
помощью VirtualDub вы легко сможете соединить несколько
видеофайлов в один или порезать один видеофайл на нужное количество
фрагментов.
Чтобы работать с этой программой не обязательно быть
проффесионалом. Достаточно запомнить минимальный набор функций и
пользоваться ими.
VirtualDub 1.9.5 is now out. This release is
also tagged "stable" and contains only bug fixes.
Previously, a
commenter asked about what changes were new to the 1.9.x series. Here's a
list:
Additional YCbCr format support. v210 and NV12 are now
supported by the blitter engine and can be selected as input and output
formats. The internally supported 4:4:4 planar "YV24" mode is now
exposed as well.
Display improvements: The Direct3D 9 display
minidriver has been updated to render several more formats in hardware,
including HDYC, v210, and Pal8. In addition, on devices supporting pixel
shader 2.0 or above, it can dither higher precision data down to 8-bit,
most noticeable with the 10-bit/channel v210 format.
Multi-frame fetching in video filters: The video filter system has been
rewritten to support a request/process model. The result is that video
filters can now explicitly request multiple source frames for each
output frame they produce. This eliminates the need to do tricky
internal buffering inside of a video filter to emulate such support and
makes it much easier to implement video filters that require a frame
window, such as field shifters and deinterlacers.
New video
filters: You can now switch field dominance with field delay, change
frame rate with linear blending with interpolate, and merge fields into
interlaced frames with interlace. The warp sharp filter is now internal,
with added YCbCr support. IVTC is now a video filter instead of a
special-cased pipeline stage, so it can be repositioned within the
filter chain and its output can now be previewed on the timeline.
Video filter updates: Levels, brightness/contrast, field swap, and
convert format have improved YCbCr support. The deinterlace filter now
supports more powerful ELA and Yadif modes.
Video filter 3D
acceleration: The video filter system now supports 3D hardware
acceleration through Direct3D 9 for filters that support it, which can
give speed improvements with a fast video card and a long chain of 3D
accelerated filters. This is still in its infancy, but expect
improvements in performance here in the future.
Video filter API
improvements: Additions to the API to aid video filter authors include
support for aligned scanlines for SSE2 support, and the ability to tell
the smart rendering system when a filter can be bypassed.
Configurable keyboard shortcuts: Keyboard shortcuts for all menu
commands in edit mode are now customizable, letting users set up more
efficient workflows.
Additional internal decoders: The internal
MJPEG decoder can now be used in 64-bit builds, and the internal Huffyuv
decoder is also useful when no 64-bit decoder for Huffyuv is available.
Performance improvements: The audio render buffer size can now
be tuned. Also, the rendering status dialog now shows you more pertinent
stats on the buffer levels of the audio and video pipelines and the
activity levels of the I/O and processing threads, giving better
visibility into bottlenecks.
Change list for 1.9.7:
Build 32661 (1.9.7, stable): [October 18, 2009]
[bugs fixed]
*
AVI: Modified indexing traversal to handle deeply nested hierarchical
indices.
* Filters: Rescaling after changes to filter chain now
extends or trims
ending ranges as needed to match changes to frame
count.
* Filters: Fixed bug where a filter capable of both 3D
accelerated and
unaccelerated modes (resize) could force a
conversion to YV24 at its
input when RGB32 was a better match.
* Filters: Filter preview no longer always runs the filter chain with
the
input video mode set to default.
* Display: Added
workaround for video card/driver combos that perform
extremely
poorly with DirectDraw/Direct3D blits overlapping a secondary
monitor. This can be toggled in Options > Preferences > Display.
* Command line: The warning dialog at the end of command line
processing is
now suppressed if /x is specified.
[regressions
fixed]
* Filters: Fixed filter errors not showing up properly.
* Filters: Fixed crash when PNG decoding error occurs with logo filter.
* Filters: Fixed random crash when opening Video Filters dialog
before
opening any videos.
