applle pro res codec showing deinterlace lines

Pretty much everything you do to a clip in the timeline is going to result of image quality unless you can start with the "pre-AIC" source.

You may want to try de-interlacing your source while re-sizing it in Compressor.

If you want to copy the Distort parameters to your footage, copy a clip that has the parameters you desire, then select all the clips you want to change and right-click on one of them and chose Paste Attributes. When the Paste Attributes window opens, select Distort from the attributes list and apply. Now all should have the same attributes.

Now just take a deep breath, not a draught... 😉

no... if it's finished it's finished. You get the quality you get. your first post said nothing about the project being finished.

But in general, the higher the initial quality, the higher the finished quality so if you were earlier in the project AND had access to the original source, you would have the opportunity to improve the end product.

In this case, think of it as advice for the future.

So no point in re sizing in a pro res sequence? The original footage was good quality bit some of it was imported using iMovie which I am finding out, but not sure, comes in with a 1440 1080 size and AIC is not a high quality one.

It's not a matter of "no point resizing", it's a matter of getting the most out of what you have. I failed to ask what the format was and assumed that you were working with SD since the AIC was more popular years ago. That type of "re-sizing" can get very tricky because of the sheer lack of pixels. If the original clips had been correctly traansferred in FCP then it would have been "expanded" horizontally to full size. This is where my suggestion about using the source would have fixed everything on the front end.

I remember writing to you a while back and you suggested compressing all the source footage to pro res in compressor before starting work on the project. I did follow your suggestion but the footage had interlcing artifacts and looked bad so I ended up using AIC codec seq. I'm trying to learn all this so any final comments are appreciated.

ProRes is actually more of an "expansion" codec than a "compression" codec. It is useful in expanding highly compressed file-based clips into a high quality, essentially lossless format that is suitable for all aspects of post. During this transcoding procedure, it is possible to de-interlace and adjust the frames to full 720p or 1080p dimensions. This isn't automatic nor is it perfect, but it does a pretty good job. As always, evaluation of the results is best done on a monitor suited to the task. I see many "artifacts" on my computer screen that do not appear on my color grading monitor and sometimes vice versa.

I am going to my post house today and have been reading that in compressor with the inspecter one can make adjustments to improve footage, like making movemnet run smoothly and sharpening edges. Is it inpertinant to ask my post guy to try and improve the image quality?

Nothing is impertinent if you are the customer, but then nothing is cheap either...😉 If you trust your post guy you could ask his opinion; he'll have the work right there to look at and may be able to help.

Thanks for all your help.
