How and to what did you export your video?
DV widescreen is still 720×480 using “non-square” pixels. The widescreen image is squeezed in to the frame, preserving the full vertical resolution. When played back, you would have to “unsqueeze” it stretching the sides back out.
If you were to make a DVD, there is a 16×9 “flag” that would be set during the encoding to indicate to the DVD player that this is widescreen and it would do the unsqueezing for you.

Couldn’t you just consolidate the sequence copying the media to another drive and open the entire thing in Media Composer? The codec is cross platform.

On the layer with the mask…hit “M” to bring up the Masks for that layer. Click on the mask name (ie. Mask 1). All the nodes along the mask should be small solid squares. Take your mouse and position it directly over one of the lines in the mask..the cursor should change from white to black, click and drag to reposition the entire mask.
To move only one node, click on the layer itself, the node points shoudl change from squares to diamonds. Then very carefully click on one of the nodes, it will turn into a solid square, changing the unselected points to hollow squares.You can animate the position and shape of this mask by hitting “MM” to bring up all the mask properties and clicking the stopwatch for “mask Shape”, start setting keyframes by moving down the timeline adjusting and adding nodes with the arrow and pen tools.
You might be able to compensate for the camera move by lowering the opacity of the top layer slightly to then be able to align both shots.
Duplicate one layer drop it to the bottom of the stack, scale it up a bit to cover any edges exposed by your realignment.Erik

Never used Procoder 1.x, however, I often see with Procoder 2 that it will misread the framerate, pixel aspect (shows 1:1 when should be 9:10, etc..) and field order (most often shows progressive when it should be lower field) of the QT reference file.
Check your “source” tab in Procoder… The field order is easy enough to fix, just select lower field from the pull down. The PA is easy, click on the “…” box and change the preset to correct. The frame rate is much harder to correct. I’ve found that the funky frame problem may be caused by using “filler” at the head of your timeline instead of just a blank black title. Often it seems that the only reliable way to get around the framerate misreads is to create a QT using “Same as source” with the Avid DV codec option checked.
Maybe Procoder 3 will address some of these problems…Just another note…For compatibility I would not create a MPEG2 for DVD with a bitrate over 7000.

If you have the drive space I’d recommend transcoding your sequence or your clips to DNxHD using the consolidate/transcode from the menu.
You can then export those clips/sequences as QT reference files or QT “same as source” movies (make sure to check the 601/709 button) to import into AE. Keep in mind that HD is upper field first and you may have to tell AE to interpret the clips as upper field first.
Out of AE, render to QT using Avid DNxHD codec, change your field generator settings to upper field first.
Then import into Avid, making sure to tell it is upper field, 601/709.Erik

I’ve never found a very good solution for this. There are utilities out there that can convert SWF to various formats. I’ve found that there are often some issues in which they don’t do a very good job, for instance in some cases flash will use hold frames instead of repeating frames where nothing on the screen changes….the conversion utilities treat this as a single frame resulting in a video that is really short.
The only dependable solution I found was to play the SWF and record the screen using Techsmith’s Camtasia, which will allow you to export the video in any number of different formats (avi, quicktime, etc..)… though probably not an OMF.
Not the greatest solution…but it works.Erik

Converting it to a quicktime using a lossless codec like Animation (if you have the space). Your stutter maybe the result of a field order mismatch…often MPEG2s from DVD and such tend to be upper field first, will DV and others are commonly lower field first. A mismatch might cause some problems.
If the MPEG was sourced from film it might also have a 3:2 pulldown, there may be options in your encoder to keep the pulldown or create 24p…you’ll most likely want to keep the pulldown.
Other possiblities…the MPEG clip is PAL, while your encoded clip is NTSC…or the mpeg just had a non-standard frame rate for video like 15fps or something…this would look fine on a computer when played back, but would have to be frame doubled to pad it out to 29.97 or 25 for video…causing a noticeable stutter.Erik

Check your import settings in Avid to be sure that “rgb” is not checked…it should be set to 601.

If you have Avid Xpress Pro HD on the same system as your AE, you’ll already have the DNxHD 145 codec…actually when working in a HDV project any effects, transitions and other renders on a HDV timeline will be at DNxHD 145 resolution.
Read about the codec here: https://www.avid.com/dnxhd/index.asp

if you want to use them on systems that do not have Avid installed…Erik

you might not have much of a choice. You’re capturing DV? 420 is PAL and 411 is NTSC.
