Ehh.. remove the filter from the timeline ??

Ah, I see you got it Seth. Good man. I would not bother re-interlacing as you will never crete the differnces in the two fields that first existed. Instead, just use some other interlaced video as a test.

Feel free to call me if you’d some help configuring for best quality. My number is on the website you’ll find in my profile.

If deleting the de-interlace effect from you existing project doesn’t work for some reason, find your “Autosave Vault” folder on the scratch disk for this project. Open it and go to the folder for the project you want to restore. Find a saved version before the time you used the FCP de-interlace. Any other changes you made to the project after that time will not be on the saved version, but it will give a back to back test of the de-interlace plugs.

If you want to keep this modified project remember to save under a new name.

George,

I’m pretty sure Seth is takling about reinterlacing a QT that he deinterlaced earlier in Compressor. Thats why I suggested that it won’t do any good because it frames now.

There actually is one way to interlace a progressive video clip, but like the process of de-interlacing, it does involve interpolation.

For the most accurate control, the best tool to probably use is AE, but you can probably do it in FCP just as well. There are two main steps: Double the amount of frames (either making it 30p at twice the TRT or 60p at the same TRT) and then assign each even numbered frame to the even fields and each odd numbered frame to the odd fields (or reverse depending on your format and/or NLE hardware). The last part is tricky because you’re going to cut the vertical resolution in half and make sure you’re back in a true 60i (29.97 interlaced) rate. Again, doing this in AE allows for the best control IMO.

Maybe I can pop out a Cow tutorial on this over the weekend.

“I unfortunately didn’t save a copy of my project before I used the FCP de-interlacer but I’m wondering if there is a way to revert back to the version of the project before I used that filter so I can compare quality side by side with the Flix Pro de-interlacer….”

Sounds to me like it’s a project. Maybe it’s just the repeated use of the word “project” that makes me think so.

If the problem is an FCP project file that can’t be untangled or wasn’t saved properly, Auto Save can be the fix.

If it’s actually a QT movie, there isn’t a fix without a quality loss. As you say, test another clip.

Best Solution: Don’t post a question and expect others to figure out your problem if you are not going to follow up with details.

Thank you everyone for you helpful suggestions.

What I ended up doing to get through this was to just simply go back to the FCP timeline, and removing all effect attributes since, besides the interlacing, all I had in there were some color corrections that I was able to re-do without too much trouble.

Then I started the process again from there, exporting in a QT ref file and running it through, Flix Pro (which is amazing, by the way, thanks for the recomendation David!) and then uploading it to brightcove.com.

This was my first attempt at a video home tour for a paying client and it could not have been done without help from this forum.

If you want to get a laugh, check out my first version on the video (when I was still exporting through 2 pass sorenson 3 then compressing through Flash 8 Encoder) to the final version.

(both are pretty crappy in my own opinion, but not too shabby for my first attempt!)

Thanks again everyone.
