Interlaced video to progressive, how to?
I’m working on projects for both web and DVD delivery. I’m working with regular DV interlaced footage.
I wanted to work with progressive footage on my projects. Reason being, is that the projects include multiple layer effects that are coming in from Motion. When exporting projects just for DVD, it seems the picture works perfectly, because of the interlaced support. Now when exporting for web, at time of compression, the is to much jitter on compressions lower than 1000kpbs, which is to high for web delivery.
I’ve used several filters to de-interlaced @ compression, but none has give acceptable results. If I can work on a progressive sequence, I should have no problems with graphics at time of compression for web (My Thinking).
I know Magic Bullet Suite allows for this in AE, but I don’t have and I don’t know how to work on AE. I was thinking, and actually have tried ReelSmart (Re:Vision) FieldsKit. But don’t really know how to implement this plug-in with in FCP.
There is a great tutorial for it here at the Cow, but it only covers AE.
I’ve found this link:

[jnolla] “But I can’t quite understand how the whole, thing of applying a video filter to an entire sequence works.”
Make a new sequence with the exact sam settings as your footage. Drag your edited sequence into this sequence and your timeline will now be one long clip. Apply filter, adjust settings and render.
The Boris Continuum Complete 4 filter set has a pretty darn good deinterlacer. You can apply it on a clip by clip basis. https://www.borisfx.com/product/continuum/
Nattress also has a deinterlacer https://www.nattress.com/Products/filmeffects/filmeffects.htm
You can also use your web compression software to deinterlace.

Do a search in this and the Compression Techniques forum. There have been discussions about the best way many times. The best way I’ve found with the tools I had was using Compressor and its Advanced Format Conversion (don’t use the deinterlace filter in it though!). It has a progressive output that looks as good as anything I’ve seen.
EdHere’s the process as I’ve spelled it out before:
Go into Compressor and in the Settings (Presets) select the Apple/Advanced Format Conversions/8-bit Uncompressed(either PAL OR NTSC).
Select the Duplicate Selected Setting (one of the 3 buttons at the top left-it’s the right one). You can now edit the setting. Double click the setting
to open the Inspector. Right under Description at the top of Inspector are 6 buttons, select Frame Controls. Select Custom as the Frame Controls
(default is Off). Select Best for Resize Filter, Progressive as Output Fields, and Best as Deinterlace. Also select Best as Rate Conversion at bottom (not sure if that’s necessary, but what the hell). One of those 6 buttons at the top of the Inspector is Filters, and one option there is De-interlace,
DON’T use that one, it’s crap, and you’ve already selected all the de-interlacing you need. -
The Boris Continuum Complete 4 – will set me back a good $800 🙁
Fieldskit was only $90.00I have created a new sequence, I’ve placed the footage there, then imported that sequence into my main sequence. I can apply the effect to the sequence, but when I double click on the sequence to bring it up in the viewer, so I can modify the settings for the filter, it takes me in to the actual sequence.
When I get through with this, do I have to change the settings of my main sequence to match does of the footage?
Thanks

Hi
use the f key to “match source” on your sequence. it will load the sequence into the source viewer like double clicking does with individual clips.

Nice tip. Faster than right click on the timeline and select “Open in Viewer.”

Or single click, then press return.

Guys, if jnolla has a combination of interlaced video and some Motion segments, could you detail the actual workflow that would be used to deinterlace the non-Motion parts and then combine it with the Motion stuff (rendered with no fields)? Would that result in the best quality in the Motion segments?
Or would you simply do the whole thing interlaced and then use the FieldsKit filter on all of it at the end? In this case the final sequence would have the same settings as the original, but the nested sequence would have the deinterlace filter applied to it.
Hope I’m not muddying the waters too much.

I’ve applied the filter, and It’s now rendering. But it seems the audio is out of sync. Do I have to manually sync the audio? How do I go about that?
After the video is render, do I have to change the settings on the sequence, to match the frame rate of the video? When I export the Quicktime Movie for compression, will it be exported at the frame rate setting, or would it still export as interlaced DV?
I looked at the reply of using compressor to switch to uncompressed 8 bit. I like that idea, what will be the frame rate after I use this method? How does it de-interlaced? Does it drop a frame, or does it duplicate the frames and combines them?
Thank you all for your posts!

Have you got a link?
Following on from your list of settings in Compressor, I’m curious about your setting for things like the ‘Anti-alias’ & ‘Details level’ settings.
I’ve made a setting similar to that which you described, and while it delivers great results, it does take a long time; as much as 105x realtime.
I have Anti-alias set at 5 & Details set at 10.
Generally, Compressor seems very slow when converted interlace to progressive, no matter the settings. (So even a poor result takes a long time to achieve!)Love to know your thoughts (and if they’re detailed already, yes, just post a link.)
cheers,
