Specifications

VideoDriver: This drop down box lets you select which software driver VideoReDo should use to display

the main video window while editing. This parameter does NOT affect the output video in any way. The VMR7

or VMR9 drivers should be used if your system has multiple attached monitors.

● DirectX - The DirectX driver relies on DirectDraw7 and should provide excellent performance on most

single monitor machines and should have the highest level of compatability especially on older systems.

● DirectX-Multi Mon: This upgrade to the DirectX driver will support systems that have multiple monitors. We

do no recommend using as it is being phased out in favor of the two VMR filters.

● VMR7: The VMR7 (video mixing renderer version 7) is available, by default, on Windows XP and other

systems where DirectX9 has been installed. It is one of the two drivers used by Windows Media Player and

works well on systems with both single and multiple monitors.

● VMR9: The VMR9 driver will work on all systems that have Direct3D installed. This includes all systems with

newer graphics cards. In terms of overhead, DirectX has the least, followed by VMR7 and then VMR9.

Audio Device:

Use default WAVE: There are two types of sound drivers on Windows system, WAVE and DirectSound.

You might want to experiment which driver sounds the best for your system. In most situations, the WAVE driver

is the "safer" choice as this driver usually has a lower latency. The latency is defined as the time from when

the program asks the driver to output a sound and it is eventually heard by the user. When using the WAVE

driver, VideoReDo's volume control affects the volume of all applications on your system. However, some

newer devices especially external USB and Firewire sound devices, may not come equipped with WAVE drivers.

Use DirectSound drivers: If you can use the DirectSound drivers you should see a couple of advantages

over WAVE drivers. (1) You will be able to select the specific device to playback your audio. This can be a

real advantage for systems with multiple sound cards or audio devices. (2) VideoReDo's volume control is

limited to adjusting the volume of the current MPEG program. In fact, you can have multiple VideoReDo

instances open each playing a video program at a different volume.

The problem with DirectSound is that some older sound card drivers introduce very high ( > 100 Msec) latency

in the audio. In this is the case, you will have to revert to WAVE-based audio.

Edit Without Audio: If there is no audio device on your system enable this option to allow VideoReDo to

open the file. This option may be useful if you are editing over a remote keyboard / display connection where

the audio is severely delayed or a remote link audio driver is not available.

Swap LPCM Audio Bytes: Enable this option if you are editing LPCM audio and the sound does not

play properly. Some programs will reverse the order of the audio bytes in a sound track. This option

will compensate for that behavior.
