Picture ‘Break-Up’ on captured footage.
Hi.
I’ve just finished a little film made in Japan, using Vegas 8.
Almost every clip where there’s any form of horizontal movement gets split into horizontal lines.
After 17 years in the camera industry I know all about interlacing etc, but this always makes the resulting footage look poor.
Most was filmed on HD, but there are a few clips in SD, too.
Both are as bad as each other.My PC was custom-made for editing and has a terabyte of memory and (according to the ‘press’) all the top-quality boards and drives to give excellent results.
(My Vegas 6 was rather better, actually!)There is no break-up if you watch the raw footage, which makes it even more frustrating.
Are there any additional settings I can use to improve the initial capture quality?
This will all be done in PAL, by the way.Fingers crossed!

Hi David,
I agree with your assessment that it is an interlacing issue. In particular, it sounds like a field order problem. As you probably know, interlaced video is captured as two fields which are temporally separated in time (either upper field first or lower field first). If you play these back in the wrong order, you will get the problem you are seeing.
This is complicated by the fact that HD is Upper Field First (UFF) and DV is Lower Field First (LFF) and you have a mix in your project. The first thing to check is the properties of the clips to make sure that Vegas has correctly interpreted the footage and has the correct filed order. One quick fix might be to reverse the field order in the render. So if you are rendering UFF switch it to LFF and see if that fixes the problem.
Somewhere in there your field order is getting misinterpreted and you need to find it and change it.

Hi David, i am having the same issues on loading JVC 720p-25/50. I tried it on Vegas 7 and it downloaded fine and as such i am capturing on V7 only……….V8 seems to have a huge number of bugs and no support as i have had it for 7 months and am yet to get a full production from the beast. Binning your captured material also caused a total crash………

Hi Steven
Interestingly the Vegas 7 captures and views the material perfectly as per the external viewing monitor, however V7 appears to have other issues when building the video.
V8 is also a nightmare when trying to build mulitple media bins and tends to crash and shutdown. Due to the nature of the work i prefer to digitise the whole tape and work from there. This appeared to be possible on Vegas 5 and DVcam…….. I also find that you cannot batch capture HDV………..

Have you tried capturing the clips using a different application?

Hi, John.
I thought it would be something along those lines.
I did see that tab and wonderd “Hmm, will this screw it up completely?”
As I was pushed for time, I didn’t try it then, but I have just fired-up the other PC, and will try another render using those settings.
The other thing I might try is to upload V6 onto the editing PC.
I seemed to have ‘cleaner’ results with that in the past.I’ll re-render the project, and let you know how it comes out.
(I shall also bear in mind the HD / SD issue for the future!)Cheers

Hi, Tim.
Not sure if you’ve seen the response I had from John Rofrano about this issue.
He says it’s an “Upper Field First” / “Lower Field First” issue.
This is complicated by the fact that HD uses ‘Upper First’ and SD uses ‘Lower First’.
I’m just about to try a re-render, after changing the setting, and see what happens.
Of course, the problem ‘could’ still be there, due the mix of HD and SD footage!!
Hey ho.
V6 never gave me these problems… I thin kI might upload V6 onto the editing PC!I shall let you know how it goes.

Hi, Steve.
I haven’t tried that, no.
Seems a bit unfortunate to have to use something else ‘outside’ of the Sony package, doesn’t it? :-/
However, if it’s going to give better results, I’ll certainly give it a go! 🙂Many thanks for the advice.
Cheers

Hi, John.
Well, I tried swapping the “Upper / Lower Field First” setting, then re-rendered the project.
Eeek! Complete gobbledy-gook!
Maybe it’s because I hadn’t changed that setting before I uploaded the actual footage, I’m not sure.Anyway, I shall do that in future and see how I get on.
Many thanks for your assistance.
Cheers

No..it is not unfortunate to use something out of the
sony package. I hardly use sony to capture my basic footages,
I most often use “WinDV”…which is a free capture utility that
is really impressive for its price and size.Steve Rhoden

There is also a free one for HD i use sometimes called
“CapDVHS”…..Therefore “WinDV” and “CapDVHS” are two
freeware that are a serious part of my workflow when
handling captures for several reasons.Steve Rhoden
