Editing a simple video using AVID MCXpress (PC)
AVID MCXpress is a full-featured nonlinear video editing system. There's no
hope of covering the full functionality on this page. I've
concentrated on a lot of the stuff specific to our setup, and tried to
cover most of the gotchas that I've found. There's not much here about
the main function of MCXpress itself, namely working with clips and
editing. That's covered in the manual and online help, which you'll want to
- Log in to Kinora (NLEPC)
- The icon for AVID MCXpress should appear on the desktop. Double click to start the application.
- The following error message will most likely appear. Simply click OK - there is not in fact an incompatability.
- AVID MCXpress will load, and the Organizer window will appear. You will now want to create a project for your video.
Creating a project
If you have some video on tape that you need to digitize, you can do
so from inside MCXpress
- Startup AVID MCXpress, and open your project file.
Tools->Digitize..... The digitize window will appear.
- If you are digitizing using the Sony Digibeta, you can use remote deck control for more
accurate control of the digitizing process. See below for more information.
- Route the appropriate deck to Kinora. For example, to route the
digibeta deck through the Web interface middle-click on the digibeta
deck and left-click on
NLEPC Kinora (PC) entry that appears in the text list on the right-hande side of the web page.
There is no image for Kinora. Telect:
telect -lsdi -idigibeta
-onlepc. See the capture page for
more on routing.
Even after you have routed your video source to
Kinora, the preview window will appear black. Kinora does not support
video preview or playback directly. Instead, you should use
for preview and playback of the video input and output. If you select
as input to viewmon (the input buttons are on the front of the monitor) then MCXpress will
display the raw input and output to that monitor.
- If your clip has sound, make sure to also route the audio to Kinora. If your input is
the digibeta, this will happen automatically. If you are using a non-digital source as input,
you will have to route the video signal through either
when you route through either of these transcoders, audio will not automatically follow the
video signal. You need to first route your audio signal directly to Kinora, and then route the
video signal to Kinora through the transcoders. You must route audio first - this
will not work if you route audio after video. If your clip does not have audio, disable the audio channels
by unchecking those signals in the digitize window:
- Click the
record button. MCXpress will immediately start
digitizing the input to the disk. When you are done digitizing, click the
You must then immediately name your digitized video clip -- the new clip will appear named
in the list of clips that appears at the bottom of the digitize window:
- You can now either digitize additional clips, or close the digitize window to return to editing
Importing existing content
File->Import->Import File(s)... and select a still image, video clip, or audio
clip that you want to import. You'll see it appear in the Project
window. You can drag it into place in the Timeline window. To make
a simple video, just import your all your pieces and drag them into
the Timeline window in the right order. If you just want straight
cuts with no fancy transitions you can just shove them all
back-to-back on the (V1) track.
You can use a clip more than once by just dragging it from the Project
window to a new place in the Timeline window.
To set the duration of a still image, you can either double click on the image in the Project window
Out markers, or you can clip it after placing it into the
Timeline (again using In and Out markers). Still images default to a duration of two minutes.
Note that you can make title frames and such with the button
in the Timeline window.
You can fade from one clip to another by using effects. Place both clips back to back on the
(V1) track, and then select the transition between them. You can then insert effects such as
dissolves and wipes. If you want to overlay two clips using transparency, then place
one clip on (V1) and the other on (V2), and insert an overlay effect.
- You can preview your video on
viewmon simply by setting viewmon's
input to be
Line B and pressing the button in
the timeline window.
Tools->Print to Tape... The
print to tape window will appear.
- Although it is possible to print to tape without using the deck control, I
highly recommend using the deck control. See below for
instructions on setting up the remote deck control.
- You'll want to record 10 seconds of black, but not the countdown:
- Route Kinora to the relevant deck. For the digibeta deck and the
Web interface, middle-click on Kinora and left-click on the digibeta
telect -lsdi -inlepc -odigibeta.
- Position your tape where you would like to start recording.
Make sure you have blacked the tape, and put down timecode. You should
also have at least 10 seconds of tape preceeding where you would like to
record so that the deck can preroll.
- Click the
record button. MCXpress will then remotely control the deck to
write out your video to the digibeta. You can then create SVHS copies from your digital master copy.
If no video or audio appears on the tape, you may need to power off and on the Targa board - some
times it gets into a weird state, and must be rebooted.
Remote Deck Control
I highly recommend using the remote deck control for both digitizing video from tape, and
for recording video output.
RS422 patch bay to route
the deck control to Kinora/NLEPC.
From the digitize window or the
print to tape window, select the deck control button:
- Set the local/remote switch to remote on the digibeta deck.
- Use the
The deck control window will appear:
Select the Sony Digibeta deck from the top pulldown menu:
If the Sony Digibeta deck does not appear in the pulldown menu, then click the
If it still does not appear, then make sure you properly patched the deck control in
the RS422 patch bay.
OK in the deck control window. Now when you either digitize or print to tape
it will use the deck control. If you need to manually position the tape, you will need to
turn off the remote control on the deck by pressing the remote button on the digibeta.
