Well, I started on my first video last night after reading all the guides and brainstorming for a few weeks. I started out by importing the DVD into Premiere with avisynth and saving the clips I wanted into HuffYUV. I noticed that the saved video didn't look exactly like the original, and I was somewhat baffled since I knew that HuffYUV was a lossless codec... After about 7 or 8 hours of intense cutting, I had 11-12gb of clips ready to go and I decided to finally go to sleep. Now it's the day after... and I realize that I had only set the project settings' pixel aspect ratio to 1.0 and had neglected to set the clip's aspect ratio as I didn't figure that it would be necessary since I had already done it once. Well... #$*(#)$@. I guess I was wrong. There's 11 hours wasted. I'm posting this so that nobody else will make the same mistake :roll: :shock: :(

First of all I don't know why you're exporting clips to HuffYUV instead of just editing using AVS file in Premiere.

I never use Premiere just to hack up clips. It's kind of like how I never use Photoshop just to convert a bitmap to a jpeg. There are smaller tools which do are more streamline. Like VirtualDub or IrfanView.

You'll have to redo all those clips now. Of course it may not take as much time now. Iam sure alot of that 11hrs was waiting for it to export to huffYUV. Another good reason not to export to huffYUV, is the huge amount of space it takes up, about a gigabyte for everyminute of footage.

Anyways, good luck in the future...

I tried just using avs clips, but that gets really unorganized. I want to be able to look at a list of clips that are labeled so I know what they are and i can look at the big picture to decide how to structure my video if everything is laid out in front of me.

question: a second ago i imported one of my .9 aspect ratio clips into premiere, and THEN changed the clip pixel aspect ratio to 1.0, and it went back to normal. theoretically then i can just use what i have already and every time i import a clip i change the pixel ratio back?

You could, but technically you don't know what Premiere did to the file when it thought it had 0.9. Maybe it resampled to 0.9 pixels, then up to 1.0 pixels.... If your clips *LOOK* okay when you import them w/ 1.0 ratio, then you're probably fine. You're most likely going to resize the resolution smaller, later anyways.

well, when the resolution was always 720x480, so its not like i LOST any pixels... if it changes the general shape of the pixels and changes each back then it shouldn't make a difference.

A word of warning to Premiere 6.0 users!

If you are getting a black screen when you open AVISynth files even when you've maximized the window, it's probably because Premiere 6 thinks you want to work with it in its proper aspect ratio. Since the resolution's 720x480 it automatically applies a 0.900 ratio modifier, making it square again. However, since we cannot resize AVISynth video, this is bad. In the forums, rhoda_b came up with the following solution:

After importing the .avs file into your premiere project. Select the file and from the Clip menu choose Advanced Options -> Pixel Aspect Ratio and choose Square Pixels (1.0) from the drop down box. Then stretch the clip window until it's the full 720 x 480. The picture should magically appear :)

To view the clips in the monitor for preview purposes etc. Choose: Project -> Video Settings and change the pixel aspect ratio to square pixels there as well and make sure the Frame Size is 720x480 or else you'll see nothing ... once again wrangle the monitor window until you have the full frame size.

To export the final project video settings for the frame size and pixel aspect ratio have to be set to 720x480 and square pixels once again. Unfortunately this means you can't export your project from premiere at a different size, but you can then just send the resulting file through VirtualDub.


i've read that quite a few times now...

from what i gather and from my experiences, if you export a 720x480 file WITH square pixels and import it back, premiere automatically changes it back to .9 because thats just what it does at that resolution. soooo... it wouldn't matter if i exported my huffyuv clips with square pixels cuz it'd just get changed back to .9 and i'd have to change it back again before i exported. since im importing back all my clips it doesn't really matter what pixel aspect ratio i exported them with in the first place, right? thats what makes sense to me.[/quote]

pfffft :lol: not for quite awhile. i'm authoring it to a dvd for myself, and for distribution i'm probably gonna keep it as a high res divx or mpeg2. when golden donut comes i might lower it though...

ok, here's something interesting.

i imported a .9 clip and a square clip into virtualdub and it treated both the same. is premiere the only program that recognizes aspect ratios? both clips in virtualdub showed up as the exact same size... wtf is pixel ratio for anyways?

Thanks for the input everybody, I've got everything under control. This is what I've learned:

Nothing in the encoded video changes when you change the pixel aspect ratio... it's kind of like setting a flag saying "please display me with a .900 pixel aspect ratio." I say this because upon changing the setting in premiere of a .900 ENCODED clip to square, it just changed it on the fly and it was back to normal, EXACTLY as it had been before. Also, I'm not sure that programs such as virtual dub even recognize the pixel aspect ratio flag... I compared the in-program size of two 720x480 clips, one supposedly encoded with a .900 pixel aspect ratio and the other with square pixels, and they were both identical in size, both before and after encoding to divx. I hope this helps somebody :)

oh... and if you have a bunch of clips to change from .900 to 1.000 in premiere, just repeat this keystroke combination:

<alt>cnp<down><up><enter><enter><down>

you could also plug this into a macro program and have it repeat the keystrokes for you while you go have some ice cream.

Well actually if you set your project to 0.9 pixels, it resizes your video to 648x480. The thing that I was thinking could possibly cause a issue that you would not notice is if you have a clip set for 0.9pixels, but your project is @ 1.0 pixels. Premiere would Resize your 720x480 source to 648x480, then back again to 720x480. Which could cause distortion or artifacts to show up.


The thing is that if it looks fine, then it probably is fine.

Yeah... I noticed that whenever I exported something, the little window that came up to display the video or bmp was in 648x480, but when i imported THAT file it was back to 720x480 .900. Like you said, probably because of my project settings. but... there are no artifacts or distortion anywhere, and everything is exactly as it used to be.

The reason is was back to 720x480 is because you exported like so ;)

Video Settings and Export Settings are separate from each other...

You could make a video thatis' 320x240, but when you goto export it change settings so that it exports at 720x480(though it'd be a bad idea).

There isn't a 'pixel aspect ratio' tag included with AVIs. All premiere does is mash the horizontal resolution..
