HDV Final DVD quality Movement problems Vegas Pro 8

[Douglas Spotted eagle]

Sounds like interlacing problems. Are you seeing these problems when playing on a set top player and television, or seeing them when playing the DVD on a computer monitor?
Not sure what you mean by “burn to HDV master tape” and “DVD from it.” This suggests you’re using something other than Vegas to render for DVD?

Thank you Douglas for your response. I send video back to camera via tools option on Vegas “print video to HDV tape”,
then burn DVD straight from camera. I’ve played back dvd
on tv & computer same interlace problem..

I believe this is part where Douglas said that you must be using some other program than Vegas since Vegas does not burn DVD’s from your camera. It is possible that whatever you are using to do this is getting the interlacing wrong.

What are you using to make your DVD?

Here is the problem: HDV is interlaced upper field first. MPEG2 for DVD is interlaced lower field first. If the program you are using to create your DVD doesn’t realize that the source has reversed interlacing it will get the interlacing incorrect and you will see the scan lines.

Here is something to try: Render your HDV project from Vegas using the MainConcept MPEG-2 render type and use the DVD Architect NTSC Widescreen video stream template with that (or the PAL version if you are in a PAL country). Vegas will understand the field order differences and render the MPEG-2 file correctly. You will also have to render a separate AC3 audio file to use since the DVD Architect template is video only. Then use those two files in your DVD authoring program and see if that fixes the problem (it should. This is how I make DVD’s from HDV all the time)

I’m confused by “straight from camera.”
If I’m straight, you’re:
~downconverting from the camera either via firewire or component output
~plugging that into a set top DVD burner
~burning a real-time output from the camera to a DVD

If this is the case, I’d expect problems. You’re also losing a tremendous amount of quality by working this way.

Why are you not rendering to MPEG2 SD in Vegas, and outputting either from the Tools option, or using DVD Architect?

Hi John, Thank you for your input. The first thing I did
was render in mepg-2. DVd Achitect Pal (Australia) widescreen
video stream. Ac3 audio seperate file. burn disc in Architech 4.5. works a treat. but scan lines in fast movement
worse. Then I was told to try burn back to HDV tape. then burn component out to DVD burner, still have problem.
could it be a propressive scan setting I’m getting wrong.

cheers Jo Payne

> …could it be a progressive scan setting I’m getting wrong.

Yea, sorry for not asking earlier but how was the footage shot? If it was shot progressive then you should set your project to progressive and render progressive. This would leave the interlacing to the DVD player which will gladly add it on the fly during playback.

I never asked you what your project setting are. They should match your footage. Are you using the HDV 1080-50i setting? You could also use the Match Media Settings option in the Project Properties.

Another thing to try is to reverse the filed order. Go into the rendering options and change lower field first to upper field first and render a bit and see if that helps.

The problem is caused by a field order mismatch so the solution is to figure out how to match the field order again or render progressive and not have interfacing at all.

Hi, i had the same problem.
Took my Sony pmw ex3 footage in HDV 1080 50i, (1440×1080), convert the mp.4 files to mxf with XDCAM EX Clip Browser and everithing looks fine in Vegas Pro 8 with the project properties set to HDV 1080 50i, (PAL). The footage is upper fied first and the project properties assumes the same.
After rendering to DVD architect PAL Widescreen, there they are, the interlaced problem in all movements, specialy the horizontal ones like pans. I tried every fields sets combinations in renderin and in projects, even tried rendering to HDV 1080 50i, AVI, tried the pre-render option,…,… notihng worked out, except… activating the switch “reduce interlaced flicker” on media properties. Took a lot of work to activate the option in every single media clip and the final quality dropped down a bit but the problem was solved, think that can help.
Maby there is a problem wiht vegas 8 pro or with the main concept codec in decoding the new HD formats, i really dont know, but one thing i know, that is not supose to happen. Complements. João Viçoso. Videographer

I’m having the same problem in Vegas 10. Were you ever able to figure out what was causing this?

[Joann Payne]

Hi Tim, There was no difinative answer to problems I was having with scan lines in Vegas 8 BUT I noticed the problems occured in video
clips I had used the ‘pan/crop’ tool. Weird hey! Vegas tends to have these idiosyncrasies. I to have moved on to Vegas 10. Touch wood, I haven’t had the movement or rendering problems since, but I did upgraded my computer to an I7 with 12mb ram. The 64bit system seems to be more stable. But there are always issues. I now have to post one on audio capture in Vegas 10 using XLR audio.
Good luck with problems. Jo
