HDV to 422 to Web... major issues
September 07, 2008 02:00PM
I am new to HDV stuff. Captured some HDV (Sony 1080i) footage to Prores 422 as described in this article: [www.kenstone.net]

I am having real problems with the quality:

- major interlacing artifacts regardless of my sequence settings (even or odd field first, doesn't seem to cure this). Picture quality is fine on the FCP, not on QT. (hi-res QT setting is on)

- Web -compression (using QT conversion, Broadband med) cures interlacing to certain extent (some still remains) but the footage is clearly "softer" and lacks the detail when compared to same compression scheme applied to DVCam (with in-camera downconversion from the same HDV originals).

- Even with manually adjusted full (25) framerate my web ready stuff still skips frames and looks jumpy, especially with rapid zooms or screen action. No such problems with DVCam.

What did I miss ??

Those aren't "interlacing artifacts." That's just interlacing. If your destination is Internet video, you should always shoot progressive.

You can always select [deinterlace] in the movie properties in Quicktime -that is what I normally do.

Don't forget to save afterwards -and make sure the clip is set to [Actual Size] before you save as that can cause problems in some apps.

You can deinterlace in Compressor as well (if you don't find it too intimidating), or this

and encode with QT pro or this which comes with a free trial

Or use blend fields filter on a copy of your master from the Too Much Too Soon FCP filters which are free...

Thanx for the responses but De-interlacing is really not an issue here.

What I am seeing is a quality hit caused by HDV to 422 to Web. Shouldn't ProRes be a better way instead of straight HDV ingestion? Is it possible that while 422 might improve the quality on DVD it somehow works poorly with web scaling and massive compression?
