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 1.9.8 is now out, with the latest bug fixes for reported problems. Merry Christmas and Happy Holidays, everyone.

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.

Build 32706 (1.9.8, stable): [December 24, 2009]
[bugs fixed]
* Fixed occasional hang with certain conversion paths from 8-bit (256
color) to YCbCr formats.
* Fixed bug where two curve points on top of each other in the curve editor
didn't save properly in script files.
* Fixed decompression error in IFF ANIM decoder when entire bitplanes were
skipped.
* Filters: Fixed glitches in IVTC pattern in the first five frames of
video.
* Filters: Fixed occasional crash when 3D acceleration is enabled and the
3D device is lost.
* Filters: Fixed bugs where the curve display would either show the wrong
frames or fail to step in certain circumstances.
* Filters: Blends are no longer allowed on filters where the input and
output have different formats; this didn't work and produced a corrupted
image.
* Filters: Fixed crash in smoother filter with MMX disabled.
* Decoders: Fixed crash in Motion JPEG decoder on certain kinds of corrupt
data.
* Frameserver: Fixed random crash issue related to stream format structure.
* Hex editor: Fixed bug where 'O' and 'S' activated open and save commands
instead of Ctrl+O and Ctrl+S.
