Encoding WMV HD with F4Mac
on Jun 21, 2007 at 2:12:30 am

Hi All!

Am at my wits end here... I am ecoding (from HDV) using FCP and am trying for reasonably high quality 720p/ 1080p WMV HD files for computer playback/download. I am encoding using flip4mac wmv pro HD...

I have tried sooo many different settings and am still having problems with the resulting product! My best results have come from using single pass and quality settings (i.e., ~85%).

The problems are sprites, or little (sometimes not so little) points or short lines of light, which appear in the picture. Sometimes there are little blocks of color like red or blue as well. On my latest encode,the music was a bit off too. The weird part is that after playing the video a few times, the sprites go away (mostly).

Please help me with this! I feel like I have tried almost everything...

Oh yeah, I deinterlaced the video on the FCP timeline first...

Do you have the latest version of Flip4Mac installed? The "sprites" problem was definitely an issue, but I thought had been resolved in their latest update.

Hi Ben! You seem to be a real expert on this art of encoding, I have been reading as much of your info as I can find.

I am really having issues with this. I just updated to 2.1.2.X today and am still having the same problems. Is there anything I can do to stop the sprites?

I am trying to encode HD files staright from FCP and from what I have read, Flip4Mac is the best way to go...would I be better off to use an intermediate file?

I have a very fast PC here which I have Sorenson and Canopus Pro on, so I have those encoding software at my disposal too...

Thanks for your comment...at least I know I am not going crazy!

Definitely go ahead and report the issue to Telestream.

I expect you wouldn't have the same issues on Windows. Go ahead and try to encode it with your other tools and let us know what happens.

Ok thanks Ben...any suggestions on a good intermediate codec to use between FCP and a windows-based encoding solution? Is Apple Intermediate Codec a good way to go? I realize I want a codec with the least amount of compression possible...just hoping for some advice.

Thanks

8 or 10-bit uncompressed works perfectly as does Animation and PNG quicktime codecs.

ProRes HQ is fantastic as well if you have fcp 6

oops I just realized you needed it to work in windows.

in that case any of these will work fine:

Animation

PNG
