Quality & compression problems

Post by GH » Tue Jun 23, 2009 8:55 pm

Alright, I'll just start from the beginning.. some of this information really isn't need but oh well.

I was pretty much doing an IC just uploading to youtube, which I eventually did. So I decided to extend it a bit and make it into a small mini-vid, I've extended it to like 0:52, it's small, I know. But that really isn't the point. I'm trying to get it compressed while remaining deinterlaced. I'm not working with deinterlaced footage, but whenever I render it in an avi it is, I know that's normal but I haven't been on the org or editing for a while and I can't really recall any technical factors that I may have known? D:

I need to figure out how exactly I should render it and what I should do afterwards to keep the overall quality(including no interlacing) nice. As I can remember you just render as an uncompressed avi, I also know how to compress the video/audio in VDub but not how to deinterlace it n the process.

I've also attempted the scan-lines method of deinterlacing which can be found here, which I can do successfully, however, I can't render it in AE where the audio comes out nicely along with it I get black blotches and the overall video quality is decreased. So far I've been through hell with this project and I'm hoping the end result will be decent. :(

In order to properly deinterlace, you're best off by using the proper avisynth deinterlacer. Read <a href=http://www.a-m-v.org/guides/avtech31/>ErMaC & AbsoluteDestiny's Friendly AMV Guides Lovingly Overhauled Largely by Zarxrax</a>, specifically in the deinterlacing section. Be sure to download the newest AMVApp that comes in the guide if you don't have it yet.
I would say that you should have good results if you used AMVDeint(mode=2) to deinterlace in the avisynth script, but if you have time, AMVDeint(mode=4) might give out better results.

That's *not* normal. You need to go to your editing program's project and export settings, and make sure that it's set to render as progressive.

In Adobe Premiere (/Pro), for example, you do this by setting "Field order" to "No fields (progressive)".

Thanks to you both.

This is my first time using avisynth and I don't think I really know how to utilize it properly. :oops:
Image After doing that I went to open>avisynthfile/"version.avs"

Thanks Scintilla, I was able to cut down the interlacing quite a bit but not completely for the new render.

Use DirectShowSource instead of AviSource for that file.
