Fussy MP4

MUTTLEY wrote on 3/15/2009, 10:53 AM
I got a small MP4 that plays fine in Quicktime but in Vegas at times has glitches and is unusable. I know it's all there since it's smooth as glass in Quicktime but not sure how to get this working right so I can use a part of it in a project I'm doing. Anyone seen this before?

I uploaded it to Vimeo and it won't play in the player but if your a member on Vimeo you can download the source from the link on the bottom right:

Hey Ray,
That mp4 opens fine in Vegas 8c, no problems?
If I can help somehow, lemme know.

Hmmm.... It opens fine in 8.0c here too - but there are a number of glitches in it during playback as mentioned.

Bizarrely, it plays perfectly in VLC. That would seem to me to indicate a codec issue.

I have seen this many times before.
I downloaded it and it has a few rough spots but basically ok in my 8.0c under Vista 64.
Still I won't use it like this but rather convert it to an avi.
I mostly use SUPER to do these conversions.

It opens fine but there are glitchy parts when viewing in Vegas that are not there when playing in the quicktime player. And those glitches are there if I try to render the clip as well.

What program is Super? I did some digging around for a freebie program but all that I tried were scams or had watermarks. I don't mind paying for software but this is hopefully the only time I'll need it. And further, confused that something would play perfect in the free QT but Vegas isn't handleing it properly.

Thanks for checking into it.

There are a number of "weirdnesses" with the original video that may or may not contribute to the glitches in Vegas:

1) The frame rate is 29.148000. (Edited for typo.)
2) The profile is "Baseline", not "Main".
3) The dimensions are 480x270 / 1.000 PAR.
4) The codec is "Base Media / Version 2".

How weird is all that?

If the originator of this video was not a complete amateur, then his / her lack of understanding of convention is a bit surprising. If Vegas is unable to handle it, obviously Sony did not contact this originator before writing their software. JMO.

EDIT: BTW, re-encoding with AVC h.264 in Super, per xberk's suggestion, produces a file that previews and renders perfectly in Vegas.

Vegas is not doing anything wrong!

QT and VLC etc can play it correctly because they'll play it back at the specified frame rate, 27.14800 it would seem (yes indeed that is a wierd number).

Now Vegas has probably been told the project frame rates is 30 fps (or whatever than darn NTSC frame rate is). You've dropped a video at 27.148000 onto the T/L and it's trying to interpolate that frame rate to your project's frame rate and do the same thing when you render.

I'd wager good money if you changed your project to 27.14800 or close to that it will play quite smoothly. Vegas's interpolation doesn't work so well with progressive footage.

You could get Vegas to fix the problem by time stretching the 27.1480 fps to 30fps at a 9.5% speedup. The video will playout 9.5% faster but that is possibly OK unless it also contains audio in which case you could have a problem.

Interesting. When I do a "Match Properties" in Vegas, I get a frame rate of 29.148000.
After doing that, it plays back perfectly (in Vegas 5.0).

That was a typo! Thanks for catching it.
I have edited my previous post to 29.148000 for accuracy. Still weird.
Bob, you might want to change your post too. MediaInfo, GSpot, and Vegas all agree on the frame rate, it was just my late-night eyes. . .

I have tried Match Media Settings and have tinkered with the framerate to no avail. There are all sorts of glitches and pixeliztion from around 00:00:21;21 to 00:00:27;08. Big blocks, completely unusable. I'm using Vegas 8.0c so not sure why you can playback without the glitches and I have yet to be able to.

Though it's a huge favor, is there a chance that anyone might convert it to avi for me and post it? I only need the segment from around 20 seconds to about 50 seconds. It's for a reel for the actress playing the real estate broker who projects the image of a house on the wall.

Would be deeply grateful!

Here 'ya go!

AVI would be a bit big on my 10Mb ftp space, but here's what I did:

--Rendered to Huffy @ 29.970
--Opened in Vegas
--Trimmed to the 30 sec. clip you wanted
--Rendered back to MainConcept AVC (VBR 2-pass) at same size as original

You should be able to use this any way you want in Vegas.

Good for 5 days.
