Working with DIVX source.

Postby RipperX » Mon Jul 08, 2002 2:06 am

I'm working with divx sources and it's in 512x384. Should I work in premiere at it's resolution or pump it up to 720x480. I know divx doesnt work well with premiere, but its works fine for me for the time being.

I've also noticed that if I convert a divx source vs a dvd source to the vcd template in TMPGenc, its pretty much the same. The difference is not that noticable. Is there a better way of encoding it in TMPGenc that is still within the vcd format standards that offer better quality? Or is the template for it in TMPGenc the only way?

Thanks in advance.

No, you do not want to resize, it will make it look squished. Leave it @ 512x384.

Check out ErMaC's guide off of the main page. While it may "look the same", working from a DivX file may make your file size bigger in the long run due to the encoder having to work around artifacts added by the divx compression.

Well, size is not that much of a concern for me, just the quality. I wanna see if I can get the best quality out of the vcd format from the dvd source.

I wanna work with dvd sources, but working with avs files at 720x480 in premiere I am not able to see the sources when workign with the plugins. This is a problem since it's hard to get the correct fade or timing without being able to see the transitions. Besides using avs method, what's a better way to edit dvd sources in premiere?

It's not because they're AVS files, it's because you need to render pieces of the videos befoer you'll see the transitions.

You won't get good quality out of the VCD spec, period. If you want to use MPEG-1, definitely read ErMaC's guide and learn to play with the bitrates and other options to get the best-quality output.

As jbone implied, the VCD spec's quality is so poor that of course you aren't going to see a difference in quality as long as your source is half way better than VCD. It's like taking a photo of the Eiffel Tower, or taking a photo of a photo of the Eiffel Tower, and then expecting someone to tell the difference when they're looking at the result shrinked to the size of a postage stamp.

Now if you try encoding to DVD spec, you will definately see a difference.

Ok, so do most people who work with dvd sources edit in premiere using the avs method? See, what I'm doign right now is trying to redo a mv that is already done using divx sources, but I find it kinda difficult to get everything to look the same without easy accessibility using the avs dvd soruce format. When I was talking about not being able to see the plugins, i meant the viewable source within the plugin windows (ie cross-dissolve). That is pretty important to me to be abel to see the extent of the dissolves.

Anyway, if you guys can suggest any better ways to do this that'd be great and thanks for all the previous info.

The only reason I'm workign with dvd sources is that I think most contests only take dvd sources right? Anyway have some experience with submitting to contests and what the typical formats that are used? :)

If you want to see the results you have to hit "Enter" and then have the segment rendered as a Preview. Then you can see what it looks like.

Yeah, I already know that. I meant that if you were to work with something else instead of avs files where you have to resize the monitor to 720x480, you can normally see the source in the view window within the plugins. :evil:

I am not sure of what you want to say here (damn my poor english), but if you want to work with AVS files without resizing your window to 720x480 you can simply add this line at the end of your AVS script:

BilinearResize(360,240)

You can work at quarter resolution until you finish your video, then you remove the line before the final export ;)

Cool, I totally forgot about that. But I'm talking about these plugin views,

If you can someone get the clips to show up there, that'd be awesome.

Oh man...

...no, you don't want to use cross dissolve, believe me. You have something extremely cool in Premiere and they are...

...drum roll...

the rubber bands!!

1) Put the first clip on track 2 and the second clip on track 3 (add track 3 if it's not in your timeline)

2) make them merge a little (this will be the duration of your cross dissolve).

3) Expand the clips and play with the little rubberbands to change the opacity of them (one should go transparent while the other should go opaque)

4) You can make interesting stuff by messing up with this things ;)

For any other question please refer to the big fat manual that comes with your copy of Adobe Premiere :P
