streams will trigger an error.
Discontinuity Checkpoints: This number represents how thorough a check VideoReDo does of the input
file to adjust for non-sequential time stamps. When a file is opened, VideoReDo checks the file, at evenly
spaced intervals, to see if the time stamps are sequential. If the timestamps are not sequential, then
VideoReDo automatically builds an internal table to compensate. The higher this value, the more sections of the
are checked, but the slower the file will open. A value of 0 disables this feature.
Non-sequential time stamps usually manifest themselves as navigation issue, where the cursor seems to
randomly jump around. Sometimes the problems are severe enough that VideoReDo will hang while trying to
open the program. In almost all circumstances, this problem can be rectified by running Tools>QuickStream Fix,
but this can add minutes to the editing process as well as consuming additional disk space for the output
file. Another possibility is to increase the number of Discontinuity Checkpoints so that the file is more
thoroughly scanned during the open.
MBytes to scan at file open: This value is the maximum number of bytes (times 1,000,000) that
VideoReDo will scan to find video and audio streams when opening a file. One reason you may want to
increase the value from its default is if when trying to open a transport stream VIdeoReDo can't find the
desired program. This may be because the original capture starts with one set of transport parameters and
then switches a few megabytes into the file to another set. Increasing this value, will trigger a more complete
scan at a slight slow down in file open time.
Convert All I-Frames To GOPs: When checked, VideoReDo will insure that all I-Frames contain
the necessary header information to be considered GOPs. This will insure the up most in DVD compatibility.
Most source files already mark I-Frames as GOPs, however, this will option will insure that behavior.
Output Diagnostic Data To Log File: Check this option to have VideoReDo output detailed data to its
log file when editing or saving a video. This option is typically used if VideoReDo encounters a problem in
the output file, such as an out-of-sync condition, and the VideoReDo support team asks you to provide
additional information. It is recommended that you leave this option off to save log file space and reduce
the time it takes to save your video programs.
Double Video Buffer Memory: The internal video buffer within VideoReDo is between 4 and 5
seconds depending upon whether you are editing NTSC- or PAL-based programs. If the audio program drops
out longer than this interval, VideoReDo can experience a video buffer overflow as it tries to synchronize audio
to sync with the video. When this option is checked, the video buffer is doubled in size so that 8 to 10 seconds
of material is retained. This larger buffer requires about 20MB more memory and slightly slows down
internal processing such as navigation through the file. It is recommended that you leave this option
"unchecked" unless your programs trigger a "video buffer overflow" error.
Note: Some digitally captured streams, especially satellite broadcasts or Tivo extractions utilize very long
GOPs. For these programs, you might experience better performance by enabling this option.
Skip Encoder Conformity Checks: VideoReDo's internal MPEG2 encoder checks to insure that the
bit stream it is encoding conforms to the MPEG2 Main Profile. If your bit stream exceeds the parameters in
the main profile, VideoReDo will warn you that you are editing a video that is out of MPEG specification and will
not proceed with the edits. Check this box to disable these checks.
Ignore Transport Stream Maps: When a transport stream is opened, VideoReDo attempts to determine
the available programs in the stream by processing the stream's program maps (PAT and PMT packets).
Many broadcasters either omit these packets or send them with incorrect information. This can cause
VideoReDo to not detect all the video and audio streams in the file. Checking this options disables the
processing of these sections. Instead VideoReDo scans the first 10,000 packets of the file and tries to
decipher what program contents are present. The disadvantage of disabling this feature is that the program
does not always pick up each and every stream, especially secondary audio streams. The preferred mode is
to leave this enabled unless your particular transport captures open with missing audio or video streams.
Encoder Quality: This parameter determines the level of quality used by the VideoReDo MPEG encoder.
The quality determines the video rate of the frames which are encoded at cut points and during GOP reduction
if you have selected to perform that function. Your choices are:
Auto: The bit rate is set the bit rate of the current GOP being cut / recoded. This option is best used
when outputting transport streams since a consistent bit rate is critical to avoid PTS underflows.
High: The default setting, optimizes the quality over speed and bit rate. Occasionally this setting can result
in frames of high bit rates that may exceed the maximum bit rate for the file. One symptom of this is a high
number of PTS underflows during output. Setting a lower encoder quality will reduce the encoders target bit
rate and reduce the possibility of PTS underflows. At its highest setting the encoder's target bit rate is the bit
rate specified in the MPEG header. Often this bit rate can be much larger than the actual bit rate. For example,
all DVB broadcasts use an MPEG header bit rate of 15 Mbps, but the video bit rate may only be 3-6 Mbps. In
this case, using the Auto or Low setting may be more appropriate.
The bit rate for the file is reported on the
Tools>Show Program Info dialog and may be changed using the
Output Options dialog.
Medium: At medium, the quality / bit rate is 2/3rds of the MPEG header bit rate.
Low: At low, the quality / bit rate is 1/2 of the MPEG header bit rate.
Output Stream Parameters:The following options deal with how video packets are packetized to form
a program stream. A program is made up of one or more elementary streams where an elementary
stream represents a contiguous stream of audio or video data. The bytes from each of these elementary
streams are broken up into fix sized packets with each packet marked whether it belongs to an audio stream
or video stream. Some of these packets are marked with a time stamp known as the "Presentation
Time Stamp" (PTS) so that when played back, the audio and video are synchronized. The default options
supplied by the program should not have to be changed.
Start Video Frame In New Packet: If checked, a new packet will be started each time a new video frame
is encountered. This option should be used when VideoReDo's output is intended to be used with other
video editors or programs that might require the files to be in a particular format.
Add Padding To Short Packets: This option is only used when video frames are packet aligned.
Elementary stream packets are normally fixed length except when they are truncated early due to packet
alignment. When checked, padding data is inserted into the program stream to preserve a constant overall file
bit rate. There is no program content in these padding packets. Checking this option (along with the video
frame alignment) can increase file size by 5% to 10%.
Align Packet Data To Word Boundary (DigiTV): Some software players such as the Nebula-DigiTV
player require MPEG streams with certain internal packet alignment. You should only need to check this
option when you intend for your videos to be played one on of these players. Otherwise, you will be wasting
bytes within the file.
Output PTS With Each Video Frame: Program time stamps are used to synchronize audio and
video streams. By default all audio packets are marked with a time stamp. When checked, each video frame
is marked with a timestamp. When not checked, only GOP frames have a timestamp. Leaving this box
checked increases the output file by less than 800KB per hour of video.
Output PS Pack Header With All Packets: Program Stream Pack Headers (PS Packets) are used to
keep the internal clock of the playback device (e.g. DVD player) in synchronization with the time stamps inside
the program stream file. When checked, every elementary stream packet is preceded by PS packet. When
not checked, only elementary stream packets with time stamps (PTS) are preceded by a PS packet. Checking
this box adds 1-2% to the output file size.
Program Stream Packet Length: This is the length of the fix-length program stream stream packets
(PES). There are two different sizes, one for MPEG2 and another for MPEG1 The MPEG2 value should
be increased to 2304 for an SVCD compliant file. The default value of 2028 is the standard for DVD
compliant program streams. The MPEG1 size of 2324 is the VCD standard and is recommended for all
Drop Frame Timecode in GOPs: If this option is checked and the video is NTSC, the timecode in the
GOP will be coded with a drop frame timecode. The drop frame timecode is designed to account for the
differences between 30 frames per second and the actual frame rate of 29.97 frames per second. When this
option is not set, the timecode in the GOP is calculated by dividing the PTS by the frame rate. This option is
not used for PAL videos.
Multiplexor Audio Lag Msec: When a program stream is written by VideoReDo, the audio data typically
trails a frame by a fixed amount of time. This parameter tells VideoReDo's internal multiplexor how long after
the video frame is written to write out the audio frame. The default value of 20 msec should be sufficient for
Note: This parameter does NOT affect audio / video synchronization. It only changes the location of the
audio packets in the program stream relative to their corresponding video packets.

This dialog lets you setup and maintain the relationship between file types and VideoReDo. File types are
defined as the text that appears after the period in a filename. For example, MPEG program streams usually have
a file type of ".mpg" or ".mpeg". When a file type is associated with a program, Windows will let you
automatically open the file by double-clicking or right-clicking on the filename in the file explorer. When you
install VideoReDo it does not by default associate any files with itself. You need to use this dialog to create
The File Types parameter page shows all the file types that are being related to VideoReDo. Notice that the
file types are all in lower case and the leading period is not included. Next to each file type are three check boxes:
File Open: When checked, files of this type will be displayed as a supported file type in the File Open dialog.
Project Open: When checked, files of this type will be displayed as supported file type in the Project
Associate: When checked, Files of these types will be marked as being associated with VideoReDo in
the windows shell. This means you can automatically open and edit files of these types simply by double clicking
Checkboxes can be toggled on or off by simply clicking on them.
Add New File Type: Type the new file type into the "Add New File Type" edit box and click on "Add Entry".
This will add the file type to the list.
Register File Associations:
Automatically On Program Start: When checked, each time VideoReDo starts it will re-register
with Windows all the file types marked with a checkbox. This option is useful if other programs compete
with VideoReDo for the same file association.
Now: Click this button to immediately register the file types marked for association.
To delete an existing file type from the list: Double-click on the file type entry.

This dialog is used to optimize the playback of your videos program while editing. It does not affect, in any
way, the format or quality of your saved edits.
Video Display Options:
Deinterlace On: If checked, VideoReDo will de-interlace the video display. Interlaced video can cause lines
to appear on screen, especially during scenes with lots of fast moving action. Deinterlacing removes these
artifacts with a very slight (usually un-noticeable) loss of display quality.
Use Video Card YUV Acceleration: This option enables causes VideoReDo to request that your video
card convert the MPEG signal from its native YUV format to the computer screen's RGB format. Most modern
video cards support YUV hardware acceleration. Choosing this option will often result in a slightly better
picture quality, and will reduce the CPU usage of VideoReDo by 5% to 15%. If you select this option,
but VideoReDo is unable to take advantage of this feature, then VideoReDo will revert, temporarily, to
non-accelerated mode. A message indicating this has happened is written to the log file. For slower
machines CPUs (less than 1GHz), enabling YUV acceleration can have a dramatic improvement of
VideoReDo's interactive response.
Note: If VideoReDo detects that you are editing HD material it will attempt to automatically enable YUV
acceleration regardless of this setting.
If you have multiple monitors on your system, you might want to disable the YUV acceleration mode as
VideoReDo only supports YUV acceleration on the primary monitor. You will not be able to see your video
picture on other monitors when using this mode.
Displayed Aspect Ratio: Use parameter to force the video to display at a particular aspect ratio. In
"Auto" mode (the default), VideoReDo will set the displayed aspect ratio according to the first sequence
header found in the file. If the aspect ratio switches in the middle of the file, the displayed picture will not
look correct in parts of the file. This parameter can be used to lock in a setting regardless of the file's aspect ratio.
Note: This parameter does NOT affect the output aspect ratio. That can only be changed on the
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.
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.

This dialog is to control the behavior of VideoReDo each time it starts.
Check For Updated Version At Startup: If checked, VideoReDo will poll the VideoReDo web site to determine
if there is a later version of the software available and inform you when there is one.
Days Between Checks: VideoReDo will check the web site for a new version at most once per day. You
can increase the time between checks by setting this field to a higher number of days.
Ask For Permission Before Accessing The Internet: When checked, VideoReDo will ask you if its OK to access
the internet. This option is useful if you have an internal firewall blocking requests from unauthorized programs.
All version request checks are made using the HTTP protocol over Port 80, just like your web browser. Other
than performing version checks, VideoReDo performs no other internet access.
Background Graphic: Use this option to customize the background of VideoReDo's main edit screen. You
can choose from one of five different dynamic and pleasing backgrounds.
Solid Color: Click on this radio button to have VideoReDo use a solid color background. Then, press the
"Select Color" button to choose a color.
Selection Time Color: Use this option to customize the Sel. Start and Sel. End font time color displayed
at each end of the timeline
Log File Folder: This edit box can be used to change the location of the log file. The log file folder contains

VideoReDo has the capability of creating chapter files suitable for import directly into DVD authoring programs.
A chapter file can created either by clicking on File > Save Chapter File, or automatically everytime a file is
saved. The parameters on this options page control the format and types of chapter marks created. For user
who are authoring directly in VideoReDo TVSuite, there is no need to export a chapter file. However, the
chapter markers generated by the parameters on this page are directly imported into the VideoReDo
Chapter Marks: This section determines the location of the chatper marks. There are three non-
exclusive options. You may select any combination of the three location methods:
At Cut Points: The method will create a chapter marker at each cut point in the file.
At Scene Markers: Checking this option will cause chapters to be created at each scene marker.
Use Equal Spacing: Create chapter markers at equally spaced intervals. You can specify how the intervals
are placed. Minutes and seconds create chapter marks at evenly spaced time intervals. Is you specify parts,
then VideoReDo will divide the total time of the output video by the number of specified parts to determine where
to place the chapters.
Minimum Chapter Interval Secs: This value resolves conflicts between the various methods listed above
by preventing chapter markers from appearing too close together.
Include first frame (0.00): Some authoring engines require a chapter marker to be placed at the beginning
fo the file. If so, check this option. The VideoReDo's own authoring engine ignores this parameter.
Output Format: This section is used to specify the chapter filename, file format. If you are using
VideoReDo TVSuite to author there is no need to create a chapter file as chapters are automatically imported
into our authoring engine.
Automatically Create A Chapter File: Check this box to have VideoReDo save a chapter file each time
a file is output. If this box is not checked, chapter files can only be created by explicitly saving them from the
File Type: This option offers two choices:
1. Text File: The chapter file will be a text file with one line per chapter according to the format you specify below.
2. DVDAuthor XML File: DVDAuthor is a free open source DVD authoring tool which can be run from
the command line. One option is to accept parameter input via an XML file. This option will create a
DVDAuthor XML file with the chapter markers properly formatted.
Output File: This text box contains a template that is used to build the chapter filename. . The "%F"
substitution will substitutes the output filename at the desired location. The chapter file is always created in
the same folder as the output file.
Output mpeg file: c:\temp\myVideo.mpg
