export has "static" on it

Jasta85 · Post by **Jasta85** » Sat Feb 24, 2007 2:25 am

i'm nearly done with my next amv but one thing i noticed when exporting is that at several points on the amv there is "static" that appears along the top of the video. Some of it is very thin and by cropping a little i could get rid of it but there are a few parts where it stretches about a centimeter into my amv. it's very brief but noticable to a careful observer

is this "noise" that the guides talk about when filtering? i just wanted to see before i start following them.

it would help if you post a screenshot...but I suspect that it's a result of exporting from premiere pro with huffyuv or lagarith as the codec.

pro's export is notoriously bad, and usually I can only get a "clean" export if I do so uncompressed.
it'l be big...but it might solve your problem.

your right, i am using huffy, and the current size of the export file is 2 gigs (4 minute 45 second amv). I would rather avoid having a bigger file as i am worried about the quality of my amv when i eventually compress it with amvsynth as squashing an even bigger file into 100 megs is bound to affect the quality

but anyway, thanks for answering my question, it generally does this with huffy? no way to clean it up? One of my previous amv actually had the same problem but i just posted it as it was since it didnt occur to often, however, i wanted to keep this one clean

in your opinion would an uncompressed file still be able to keep decent visual quality after processing it?

I think I'm using the same version of pro as you Jasta and I've never had a problem with a huffy export, I'd be interested in knowing exactly what is making it stuff up for you (so I can avoid it) if anyone has any ideas.

thats kinda incorrect - the size of a lossless file doesn't directly effect the quality when compressed.

have you tried using another codec such as lagarith or uncompressed to see if the problem appears on those codecs.

i tried uncompressed microsoft avi as the filetype in one test and couldnt even play the file when it was exported, i then tried microsoft avi with lagarith lossless codec and it was even worse than the huffyuv one (maybe because my project settings used huffyuv), i might try importing the project into a new one that has lagarith lossless as the project settings and see if that works better. i also tried to take screenshots as an example to show you but for some reason it doesnt show up in the screenshot which really puzzles me.
btw, was there a specific name of the uncompressed codec i should try?

i beleive i have solved the problem, i had optimize still selected and while this is nice for previews i had heard it can cause problems with exporting and bingo, when i deselected it almost all of the static went away, there are maybe 1 or 2 occurences now where there used to be a dozen and they can easily be gotten rid of by cropping a few pixles off the top of the screen

anyway, just putting this out to anyone who was interested

I have this problem when exporting from premeire pro in huffyuv, it only happens with the new version and the two old version give lines horizontally. Is that the same? How do I fix that also?

This is a known issue with Premiere. It's done this since 5.1, in fact my earlier videos I didn't even crop it off. I haven't had an issue for about two years, but before that it happened in almost every export I had.

hello,

i'm new here and to AMV and have a similar problem.
when exporting in premiere, the only codec that does a decent job is Huffyuv, but the files are indeed huge.

is the only way to get a good quality and reasonable size in premiere is to encode it again elsewhere?

i just have no idea...
