Does your camera shoot true 16:9 widescreen or does it crop 4:3 to 16:9? Without seeing what you are seeing it is hard to tell you what to do. There are a number of cameras that have a 16:9 mode that is NOT really 16:9. It’s 4:3 with letterboxing (i.e., black bars on top and bottom) burned into a 4:3 image. Without knowing if your camera is true 16:9 or fake 16:9 it’s hard to say what to do. What is the model number of your JVC camera?
If your project is set to widescreen and your preview is set to simulate the device aspect and your video is not filling the screen, check the properties on the Media tab and see what the Pixel aspect ratio is set to. It should be 1.2121 for DV Widescreen and 1.3333 for HDV widescreen. If it is not one of those two, then that’s the problem. Change it to what it should be and see if that helps.

Hi Geoff,
Sorry I missed the reference to Movie Studio in your original post. You are correct GearShift will not work for you.
> I see Vegas will only let me set my pixel width as high as 1,440. Don’t I need to set it to 1920 to preserve the quality?
No. 1440×1080 @ PAR 1.3333 and 1920×1080 @ PAR 1.0000 are the same size. So you are not loosing any quality.
> I don’t suppose there’s a way to prerender video, but not have it invalidated when it’s modified on the timeline?
No, but that’s why I suggested just rendering to another codec that is easier to edit with. Since Movie Studio doesn’t have the CineForm codec, you could render to MainConcept MPEG-2 using the HDV 1080-60i template and see if the M2T file it produces runs any smoother. It should and if it does on your PC, just use that.

Yes, GearShift will handle the EX1 files just fine. When I say “HDV” mean any variant 1080i or 720p. Gearshift can use native .m2t, .mts, .m2ts, or .mxf files directly with DV proxies or any other file format that Vegas supports if you generate both the CineForm and DV proxies.
Try it and see. If you have any questions you know where to find me. 😉

> why not simply add text directly in vegas? there’s nothing that PPT really offers that exceeds the ability of vegas.
Yea that’s what I’m thinking. Drop the pictures on the timeline, add a track above them and drop some generated text media for text. It would be a lot easier than messing the Powerpoint.

ROTFLMAO… Who ya’ gonna call?
Yea, I agree… this is definitely a doom9 project.

What Douglas is saying is that you should seriously consider rendering the video to a codec that is more easily edited like M2T or CineForm AVI. The CineForm codec can be found in Vegas under the AVI templates with names that start with “HDV” and end with “intermediate”. They are very high quality and will be virtually lossless for the transfer.
If that doesn’t solve your jumpy preview problem, we (VASST) make a plug-in to Vegas called GearShift that will render to both CineForm and a DV Widescreen proxy and alow you to edit with DV proxies and render with full quality CineForm HDV. There is a 15-day free trail if you’d like to test it out.

> trying to choose the correct settings to render files to quickly / efficiently.
Quick and efficient are not two words that often go together when rendering. You can get quick but it won’t be very efficient… you can get efficient but it won’t be very quick. 😉
> Thus far I have chosen to render to wma Default template
WMA is an audio codec so I assume you mean WMV and never use the Default Template. Under WMV there are several templates for HD. You should use one of them as a starting point. It may be all you need.
> I have chosen to render… 1440 x 1080 – 25 fps…Pixel aspect ratio 1 (square)
Those two parameters don’t go together. 1080 HD is either 1440×1080 PAR 1.3333 or 1920×1080 PAR 1.000. So if you want a Pixel Aspect Ratio of 1 (square) you must use 1920×1080 to get the resolution correct. Personally, if your footage is 1440×1080 I would render at 1440×1080 with a PAR of 1.3333.
Bottom line: If you select the WMV template 6.7 Mbps HD 1080-25p Video you should be fine.

This is happening because the aspect of DV and DV Widescreen are different. If you want to see exactly what is happening, change your project to DV for a second and view the text. You will see that when in DV mode, the black bars are really part of the DV frame and track motion will gladly composite the text over the bars since they are a valid part of the video in DV mode.
The workaround is to use Pan/Crop instead of Track Motion to fly the text off the bottom of the screen. Pan/Crop will correctly mask the text once is has left the 16:9 crop frame.

> What if I first capture while downconverting to DV – complete the edit, and then re-digitize at full HD. Would this be possible?
Unfortunately no. Vegas uses a different capture program for DV and HDV so there is no way to replay the DV capture in the HDV tool. What we at VASST have done, is create a plug-in to Vegas called GearShift that will convert your HDV footage to DV Widescreen for editing and then it swap out the DV media for the HDV media for final rendering. It does the same as you described except that both HDV and DV media are on your hard-drive at the same time. You can delete the DV media before you archive your project so it’s a small price to pay for DV editing performance on HD projects. There is a 15-day free trial so you can try it on a project and see for yourself.
> As far as the handles were converned, I was interested in limiting the amounts of video on my system by performing the basic shot selection during capture from the production notes provided.
You can certainly mark your in and out points a little before and a little after during capture to make the handles yourself. It’s just that Vegas doesn’t do this for you.
> I did the >Remove from project. Delete files> thing, but the files were still on my hard drive.
I works for me. Vegas does ask some intimidating “are you sure” questions after you make the selection so be sure to answer YES and the file will be deleted from your hard drive. I use this all the time to get rid of bad takes.
> It would be nice to have motion tracking in Vegas…perhaps in a later version?
Considering there are tools like Boris FX and After Effects that already do this, it’s not very likely that Vegas will take this on but… you never know. I have to agree, it sure would be sweet.

> So, how do i extract the ac3 in the first place?
You need to find an AVI demuxer to split the streams.
