Vegas Video discussions from 2005 (Q1Q2)

Ineta Salna · January 7th, 2005, 07:41 AM

I have Windows XP and there are no large pictures in the project and even more the source files are in MPEG 1 format and I'm rendering the video in the same format. Upon my friends advice I I tried to render the file on other HD (not the one where the source files are kept) and this time it worked fine. I'm still confused I had no such problems with Vegas 4 even when I rendered very complex projects, strange, I do wonder is this characteristic to Vegas 5?

Edward Troxel · January 7th, 2005, 08:31 AM

Rendering FROM Mpeg1 TO Mpeg1 *could* be the problem. MPEG is NOT a good editing format. You'd honestly be better off taking the original MPEG file and rendering to a new DV-AVI file, editing with it, and then rendering back to MPEG1.

Render the way you are, every frame must be decompressed and then recompressed - even if you have not affect that frame in any way!

Steve:

Correct, capture and print are done using Connect HD 1.5.2. Of course a future version of Vegas will have integrated capture / print, just like everyone else.

I thought Sony was attempting to position itself as a HDV 'pacesetter' rather than a follower?

I'm attempting to render a short video clip which includes an animation and a video, combined together into a single video image. I created a 1/4 frame mask for the video in the lower left corner of the animation.

The animation is a1.1 gig avi which plays very smooth by itself, but when rendered to mpeg format (so I can burn the movie to a DVD for set-top playback) the 1 gig avi is reduced to a 45-60 meg mpeg file. The quality suffers tremendously and the animation plays back with stutter.

I've tried adjusting the CBR and VBR settings, reducing the I-frame interval, set the "Video Quality" slider to "High", de-selected "Allow field-based motion compensation", and altered the "DC coeficient" up to 10-bit. All settings render out with poor results.

Any idea what settings would optimize the render of an animation?

I can imagine resolution might be a factor in this as well. If you are
not watching the preview in full resolution some interpolation is
going on etc. What happens if you render at the preview resolution
(shown underneath the preview screen), ofcourse this will lower
your movies resolution... but if you want it to look bad that is okay
I'd presume.

Rob Lohman · January 9th, 2005, 05:58 AM

Have you upgraded to the latest version of Vegas 4 or 5 (depending
on which you are using)?

Rob Lohman · January 9th, 2005, 06:47 AM

MPEG rendering is a difficult art, please use the search button
above, select the vegas forum and enter MPEG as keyword to
find lots of threads on the topic.

Although the quality of the MPEG-2 encoder bundled with Vegas
is good, there are better encoders out there.

I have no idea what you are getting at with this 1/4 frame mask,
but I would take this 1.1 GB (I presume uncompressed avi?) file
and load that into a new project. Then create an MPEG-2 file from
that, see how that looks.

Also make SURE all your settings are correct and the same, this
includes your project settings and your export settings. Make
sure interlaced/progressive is especially correct.

Yes, I am running 5.0b, I'll try upgrading to "d".

The audio envenlope problem seems to have only been for that one project, but I am still having issues with the pan/crop system.

I agree wholeheartedly, Ray. And regarding that support and energy, here's to Edward Troxel (and Rob Lohman). The resonsivenss and quality of support in this forum is high even by DVINFO standards. Sony should declare these guys as an asset on their Balance Sheet. Thanks guys!

Hello. I don know why when working in PAL and exporting to wmv if i touch any settings i cannot use 25 fps.

I mean, if i take for exaple the 256 setting and render the project it looks ok. But if i do minar changes as changing audio mode to mono for exaple, and i come back to the frame rate setting it moves automatically to 30 fps. Writing 25 would not fix the problem because as you move bacj 30 fps are again selected.
Anyone has notice this? how can i fix this problem?

Edward Troxel · January 9th, 2005, 03:35 PM

Have you tried changing the zoom level in the Pan/Crop window? Perhaps you're not seeing it because it's too big to fit in the window at that zoom level.

Alain Aguilar · January 9th, 2005, 10:47 PM

The animation codec works well, if not the best to output files

Rob Lohman · January 10th, 2005, 03:48 AM

Which version of Vegas are you using? Did you upgrade to the
latest version 4 or 5 of Vegas?
