Any video experts who can lend a hand?
 
My video guy is having a baffling problem - I know nothing and can't help - but I'm hoping someone here has an idea on how to tackle this.

The widescreen clips he's been producing for a while have been fine, but now, all of a sudden, his new clips look like they're in a much smaller "window" even though they're still in a 1280x720 container. That is, the area where video can be seen is much smaller than the entire 1280x720 pane.
To try and show what I mean: sample screen grabs:
OLDER, GOOD CLIP: http://www.cigargirl.com/video1.jpg
NEWER, SMALLER CLIP: http://www.cigargirl.com/video2.jpg

He swears not a single setting has been changed on the camera or in Vegas, and he can't come up with anything that would explain what's happening.

Anyone have a clue as to what may be going on?
Thanks :)

Yes, same export settings as well - and sorry for the double post of the same url.

The dimensions of those caps are different.. 1280x720 and 1706x720... One says it's from Windows Movie Maker... That program has "issues".. Especially if you don't set the right aspect ratio..

I only used Windows Movie Maker to do the caps quickly - the videos have all been done in Vegas.
I'll upload samples from each of the clips in a minute.

MikeSmoke 07-14-2011 11:07 PM

OK, here are samples:

OLD CLIP - came out fine: http://www.cigargirl.com/video1.wmv

NEW CLIP - came out small: http://www.cigargirl.com/video2.wmv

They're not converted exactly the same... I can tell cause the audio format is different and one has WMFSDKVersion : 11.0.5721.5275 and the other WMFSDKVersion : 11.0.6002.18049

It's hard to figure shit like this out unless everything is identical.

When you're looking at the versions that are different, are they straight from the camera? Or after they've been converted with Vegas? To truly see if it's a problem with the video from the camera, you would have to take a new "raw" and an old "raw" and then do the exact same conversion on both.

I've seen something similar to this in the past, and it had to do with aspect ratio settings.

It was after they were converted in Vegas, not straight from the camera.
My video guy has just gone to bed (he's eastern time, I'm west coast) - will get him in here tomorrow to help me answer the questions. Thanks :)

jMEGA 07-15-2011 12:16 AM

Video 1 has Frame rate: 30.000030

Video 2 has Frame rate: 29.970089

I would try using one of the built in export settings and see if you can get good results and modify the settings a little at a time to see what breaks it.

MikeSmoke 07-15-2011 12:50 AM

Thanks, guys.
Will pass all this along - if you can stop by the thread tomorrow after my guy has a chance to get in here and digest it, I'd appreciate it :thumbsup

MikeSmoke 07-15-2011 11:41 AM

Well, he's solved it - sort of.

For some reason, the earlier videos were rendered in Vegas with pixel aspect was 1.0 square. The later videos were done in 1.2121 DV Widescreen and looked smaller.

We don't know why the 1.0 square look good and the 1.2121 come out smaller, though - if anyone has an answer to that it would be greatly appreciated :)

PR_Glen 07-15-2011 12:23 PM

that was the one problem I had with vegas video when I used to be an editor... exports... the variables are so huge. We used to get content in all sorts of formats so finding the perfect one for each was tough...

Great program for editing though, very straight forward and endless amount of features.

1.2121 is a much wider pixel, Mike. If your camera has square pixels, you must use the square pixel setting always when working with footage.

A lot of the older HDV cameras cameras shooting 1440x1080 used that pixel size to end up with the correct 16:9 aspect ratio.

Shooting 1920x1080 and 1280x720 have the 16:9 ratio built in, using square pixels.

MikeSmoke 07-15-2011 12:31 PM

Thanks. That helps a lot :)

NoWhErE 07-15-2011 12:42 PM

Its a common mistake alot of video editors make.

I corrected 2 of my guys today having the same problem.

FYI, many HDV cameras like the popular Sony FX-1 shoot at 1440 x 1080 with a 1.33 pixel aspect ratio to achieve a 1920 x 1080 video frame, not a 1.2121 p.a.r.. Just do the math!

Speaking of... what do you think a used Sony FX-1 is worth?

I don't know offhand, but it's a very popular camera so I would look at whatever they are selling for on Ebay to get a realistic number. I would sell mine since I have moved on to a Sony EX-1, except that I have one small client that still prefers HDV tapes since he edits in iMovie which cannot handle the professional XDCAM EX codec. Plus the firewire port is burnt out on my FX-1 anyway- not an issue or me since I still have a Sony professional HDV deck- and that would kill re-sale value anyway.

I thought about doing the math, but then I figured the point would be the same either way. :thumbsup

Mike,

I just spoke with him he said he had this figured out. Is that the case? I could head over to his place and take a look at his set up if you need me too.

marcop 07-15-2011 03:15 PM

I only ever hear of webmasters using Vegas... shooters and pro editors seem to use Premiere, FCP, or Avid. Is that a valid observation?

Hi Michael -
Thanks. He's got it figured out now - this was indeed the issue and everyone here was great in helping us out.

Not a lot of people here would get the reference, but you might (I think).....
to paraphrase Dobie Gillis....."MATH!!!!!!!!!!!!"
(I know, Dobie said work, not math, but the emotion is the same ;) )

Thanks :)
