Compression quality in Premiere @75%... Why not @100%???

[HAGGARD]

Hi,

Why can't I set the compression quality to 100% in Adobe Premiere???
Tried all different codecs (eg. DV-AVI, Huffyuv, frameserve), but qualitysetting can't be changed!!! In my case it's ALLWAYS @75%...
What is wrong...??? I've found out that it IS possible (see picture), but how???

How are you capturing?

When you start Premiere do you select full-screen DV as your project type? If you capture via a firewire card into full screen DV I don't think you can capture at *less* than %100 -- at least none of my captures have ever been less.

I don't capture with Premiere... I use Pinnacle Studio 8 for capture and edit and use Premiere for after effects (eg. Scrollers).
This because Studio 8 shows me a thumbnail everytime a new scene is recorded (everytime record is pressed). I find this more easy editing than in Premiere...
Do you think this could have to do something with the compression quality setting??? I don't thinks so, because also newly created AVI's (eg. title only) in premiere also have quality setting of 75% when rendered to whatever codec...

So why don't you try capturing in Premiere and see what happens?

Also, when you are creating your effects in Premiere are you opening up a project as a full-screen DV project?

I won't be at my Premiere machine until lunch so I can't check further. And I know nothing about other video programs.

Hmmm,

Maybe I should give it a try...
But I still think it's strange though!!!

I always start with the DV - PAL real-time preview preset...
Then Adobe reports : Depth: Millions, Quality: 100%...
When I create a clip (eg. Bars and Tone) and then export timeline to movie then :
compression: 'Microsoft DV (PAL)' @ 75%!!! or
compression: 'Huffyuv v2.1.1' @ 75% or
compression: '(uncompressed)' @ 75%

If I try settings and then in the video-tab, quality is greyed out and reports 75%...

WTH is going wrong???

I had the exact same problem about a year ago, and I have absolutely no idea why. This is the only way I found to get around it:

-When exporting, click settings, then click load and choose one of default formats from the menu.

Hope that helps

I had the same 'problem'. When I changed the export settings to AVI - Uncompressed it changed to 100%. After I changed it back to DV-AVI, it still said 100%.

When I changed to AVI - Huffyuv it changed to 75%, and changing back to DV-AVI still showed 75%.

It seems to me that it's a bug in Premiere and changing to DV-AVI doesn't change the percentage. Perhaps someone knows if DV-AVI is always at 100%?

Could be a bug. If so, two questions:

1) What version of Premiere? (I'm using 6.5 -- never seen this but then never use any other export other than DV-AVI and MPEG).

2) Have you reported this on Adobe's Premiere forum?

I'm sure the latter will result in answers from the very knowledgable folks there.

[WeBe]

1) I use Premiere 6.02
2) No, I didn't report it on the Premiere forum

For me personally this 'possible bug' isn't an issue, because I don't see any difference in quality between the original and rendered DV-AVI.

After I've converted it to MPEG2 with TMPGenc and have authored and burned my DVD, the quality excellent, especially when using an s-video connection!

Initially I thought I just used a wrong setting somewhere. Now I see that you have noticed the same 'problem', I'm getting curious if 75% is really the quality setting or if this is indeed a bug.

Wim,

Actually, I've never seen this problem -- I was just responding (as you ) to the original poster. I don't know that it exists in 6.5 (it may very well have been fixed). 6.5 is worth the upgrade alone for MainConcept and/or the titling.

If the original poster is still worried he might very well consider visiting Adobe's forum and posting there. I'm not going to worry about something I haven't seen.

Sorry, a little misunderstanding.

mkelley,

I also use version 6.5 and also downloaded the latest updates for it!!!
I did some tests to check if quality really deteriorates, but this seems not the case.
I made some kind of testscreen (RGB with 100% red-bar, 100% green-bar and 100% blue-bar and a greyscale from 0% (black) to 100% (white)).
Exported this with huffyuv (uncompressed), imported it again, exported it with huffyuv again and so on a few times.
After a few exports/imports, saved frames as bitmap and openend them in PaintShopPro and used the "color picker" to test if colorvalues changed (this could be an indication that quality is deteriorating), but values are all the same as in the original bitmap!!!
It's probably greyed out because this setting isn't used when exporting to uncompressed format like huffyuv, though I don't understand that quality setting isn't reset to 100% when DV-AVI is selected again.
Maybe it isn't even a bug!?! because when exporting to DV-AVI there is always a recompress so quality of export is always deteriorating!!! Somewhere on this forum I've read an article (as answer to another post I've written) that the Microsoft DV codec isn't one of the best (what is???) codecs...

Thanks anyways for all the replies.

I haven't read that, but I have read that there are some advantages in using a high-end codec, such as MainConcept's, if you are going to be doing a lot of exporting/importing (maybe a lot of AE layers back and forth?).

For one export out the MSDV ought to be just fine.
