Capture DV Video to DVD looks bad...

Hi,

I am having serious problems and hoping you all can help. I'm using MSP8.

I have a 8mm tape that I am capturing to DV avi. Based upon the screen of my camcorder during capturing, it appears that is was recorded in 16x9 format.

After I capture it, MSP8 says its a 4x3 fromat. Never the less, after I make my edits and additions of music and stills, I encode it to mpg, DVD 16x9, square pixel rendering, etc., I also use the crop, to crop out the bottom 10 pixels to remove capture garbage. The encoded video seems fine on the PC. However, after I export it to DVD authoring, the file looks bad.

It's hard to describe, its mostly in the movement of the camcorder footage, the pan and zooming. This isn't from a wrong field issue, I have already been through all of that in my previous life.

Outside of what my mistakes have been thus far, can anyone explain to me, how to take this apparent looking 16x9 raw footage and preserve it at 16x9 and also how they would recommend getting rid of the capture garbage at the bottom of the footage?

Thanks and sorry for the long post.

Capture garbage is no doubt the analogue problem that just isn't seen when shown on a tv because of overscan, so unless your movie will only be seen on a pc I'd forget about it.

Normal, I don't worry about it since, the audience is usually 4x3 TVs, however, since this is a 16x9 source, you sill see the 'garbage' on the 4x3 TVs.

I doubt it. 16:9 on analogue cams, AFAIK, were always 4:3 with only the centre lines used (letterboxed).

That was my thought as well. However, I never ran into this situation, how would I handle my task/requirements?

If the video gets rendered at 4x3, it looks squished...

Can you post a copy to either one of the video hosting sites? Veoh (preffered) , You tube, or Photobucket?

Actually, just a small, maybe minute or two of the problem would help..

Thanks for the help. I'm not sure that uploading is necessary as of now. I figured out what was causing the problem. When I was using the crop feature during the encoding process, for some reason it is causing the video when authored to a dvd to look distorted, mostly during high movement frames. The weird part is, that the pre authored mpg looks fine and if I don't use the crop feature, it authors fine as well.

What alternative do I have to get rid of this analog garbage at the bottom of the frames instead of using the crop feature? Thanks,

black mask?

Use (rent/borrow?) a digital8 camcorder that does the 8mm -> digital conversion in the camera (rather than whatever analog capture method you used), and capture via Firewire instead.

If the camera recorded 16:9 on the 8mm (this seems very unusual for an analog camcorder??), but the analog capture you did flagged it as 4:3, you should be able to just change the aspect ratio (w/o "keeping aspect) via stretch etc and maybe the outside parts go away... I'm unclear why stuff at the bottom would be appearing for 4:3 vs 16:9 TVs, since overscan isn't affected by aspect ratio??

I think maybe the crop/zoom you used before converted the field-based video to frame-based (poorly), which caused your motion problems (stuttering?).. which makes sense if it zooms in a few horizontal lines (messing up the interlace).
I agree that a black mask on top of the analog part would be best.

you could try putting the entire video into a moving path and enlarging it and positioning so the bottom few lines go off the visible screen.
Might work.
