Working with 720×480, 29fps footage

[John Rofrano]

Which render type are you using? You should be using Video for Windows (*.AVI). if you select the NTSC DV template from there your footage should look exactly like the original. In fact, if all you do is cut out sections and don’t apply any FX is will BE the original. i.e., Vegas Pro will just copy source bits to target bits unchanged.

Hey, John.

Thanks for the reply. I tried what you suggested, but the resulting clip still looks worse than the original.

The original file is a .mpg file and SV says it’s 720×480, 29bps.

1. I put in on a track and agreed to match the settings of the video

2. I clipped part of what I what rendered

3. I went to “Video for Windows (.avi)” and selected “NTSC DV Widescreen”, which has the “=” sign saying it matches settings.

4. I rendered it.

Resulting clip doesn’t look as good (but might be better than the original .m2ts rendering I did.

I am missing something? Should I disable resample?

Thanks.

Very basic, but do you have your File|Properties Video tab|Full-resolution rentering quality set to BEST?

No, it actually was set to “Good”. But switching it to “best” didn’t really help.

The resulting clip looks nowhere near as good as the original. When do the AVI version, it looks like little lines sticking out of the things in motion. Interlacing problem, perhaps?

[John Lee] “The original file is a .mpg file and SV says it’s 720×480, 29bps.”

Sorry I thought you were working with DV video. MPEG2 is already low quality. DV is compressed 5:1 and MPEG is compressed 25:1 so it is 5x more compressed than if you had the original DV footage. So forget my advice. It was based on a misunderstanding.

[John Lee] “Resulting clip doesn’t look as good (but might be better than the original .m2ts rendering I did.”

Try rendering back to MPEG2. Use the MainConcept MPEG2 type and find a template that matches your source.

Yes, that sounds like interlace problems. What do you have your Deinterlace Method set to in your Project Properties?

It is set to blend. Should I change it?

I also went to MainConcept mpg and couldn’t find one that is compatible. Tried a few different ones and they all look jagged (like there are comb teeth coming out the sides of all images.

[John Lee] “It is set to blend. Should I change it?”

No for now that’s fine.

[John Lee] “I also went to MainConcept mpg and couldn’t find one that is compatible”

That doesn’t sound right. Either Program Stream NTSC or Program Stream NTSC Widescreen should have matched.

What do you have your project properties set to? You should make them match your media.

[John Lee] “I also went to MainConcept mpg and couldn’t find one that is compatible. Tried a few different ones and they all look jagged (like there are comb teeth coming out the sides of all images.”

Were you viewing this on an interacted device like a TV? If you are viewing this on a computer monitor it’s supposed to have jagged edges. The video is interlaced and it needs to be viewed on an interlaced device like a TV.

How are you planning to deliver this footage? DVD? Internet? It’s not clear what you are trying to do (other than edit MPEG video)

I’m clipping some video someone gave me, and it’s 720×480, 29 fps. On it’s own, it’s looks ok. But when I use SV to clip it, the resulting clips look much worse.

Back to your original question. If all you want to do are basic cuts, maybe add titles, etc., you want to use software that will smart-render (not re-render) your footage. Vegas does smart-render MPG footage, but it is very picky (obviously, it hasn’t worked for your footage). Others are more forgiving. Suggest you try something like VideoRedo, TMPGEnc MPEG Smart Renderer or Womble. Most have a free trial. You can also search for freeware tools on Videohelp.com. Sometimes, using Vegas is not the answer.
