Thanks

Is it the effect used in fight scenes, such as Gladiator and particularly in WW2 war films (Saving Private Ryan) etc., where the images are sharpened and slightly stuttery (to simulate the realness and immersive-ness of it I guess)? Along with using colour filters (to make it look earthy and grey)?

Many thanks for that Kyle! Very helpful stuff there. Everything makes sense now, the way you say that the television “scans” and projects only half the lines at a time (ie. even or odd).

Glad you mentioned that de-interlacing was a lossy procedure – I was originally thinking that I could de-interlace captures to process them with effects and then re-interlace the final product for authoring to DVD.

I didn’t realise de-interlacing just threw away data (about half of it, I guess now), but I thought it just skewed it so that the previous and present frames were merged to form a full progressive image. Ie. merging the odd lines of the previous frame with the even lines of the present frame to restructive a non combed image, so you could process it properly with effects and then re-interlaced for burning.

One last thing, how do I know if the camcorder and/or DV capture is upper-field or lower-field interlaced?

Thanks ever so much. Have a good weekend. 🙂

>> “If you are exporting to DVD why deinterlace? you would be limiting the DVD to playing on progressive scan DVD players, if you have a interlaced DVD it will playback on different players and Screens”

Must admit I’m very new to all this. This is my first project and it’s been a very steep learning curve.

So DVDs are interlaced, too?

How does a DVD player know if the video material on the DVD is interlaced or not? For example, if you burnt a non-interlaced AVI file onto a DVD? I’m not sure that any of the AVIs I’ve ever seen have been interlaced? Or is interlacing added to AVIs just before burning to DVD?

Another reason I thought it was best to de-interlace, is when I’m using plugins such as Twixtor (motion speed remapping). – I imagined Twixtor would work a whole lot better on a clean de-interlaced image in Premiere Pro as opposed to a fuzzy interlaced one?

I just don’t want the fuzzy, ghostly, echoey double-image interlaced trails that are shown in Premiere Pro to be shown on the final DVD output (ie. when it appears on the television.). De-interlacing the captures gives a clearer image to work with in Premiere Pro. I assumed this is what is carried forward? WYSIWYG and all that?

My brain’s interlaced, in trying to understand it all! 😀

Help much appreciated. 🙂

Thanks for the reply. I will eventually be exporting it to DVD.

This is what I’m finding when exporting it to AVI format:-

The one on the left is a screengrab of an exported AVI (played via Windows Media Player Classic) without processing. The pic on the right was de-interlaced using a plugin in PremierePro before being exported to AVI.

The original camcorder captures within PremierePro are interlaced. I can only think I recorded/imported them into Premiere Pro incorrectly? Or is all camcorder footage interlaced? So that you normally have to de-interlace them once captured in a program like PremPro?

Is it better to de-interlace all the captures before adding any effects? (I’m guessing so).

And, are all de-interlacers the same, or do they each do the job differently (with varying results)?

Thank you!

Thankyou! Took me a good while to find that little arrow to expand the properties. 🙂 Tiz like a Rat’s maze to the beginner.

Thanks again. 🙂

The interlacing was there after capturing the video via firewire into Premiere Pro from my mini-DV camcorder. I didn’t realise it was there until I exported it to AVI, due to the preview window in Premiere being much smaller than full size.

It means I have to go back into Premiere Pro and process all the captures with a de-interlacer plugin.
