Is there a way to turn 60i to 60p?
 

For sports. Created the project as 720p60. However there doesn't seem to be a way to treat interlaced half frames as full frames. This is common in many sports analysis programs. Was hoping to find a way with PP. So far attempts included frame options and Field Interpolate video effect.

Thanks,

The (Premiere) project is 720p60, but what format is the original footage? 720p60 as well or something else?

The original footage is 60i DV. There are 60 720x240 frames there that several sports programs turn into 60p. However, it seems that PP wants to turn it into 30p duplicating frames. If you turn off deinterlacing and interpolation, you get two frames overlayed in each frame.

Is there a way to get it to split the frames with odd on one and even on the other?

While I'm sure there is a way to do this in PPro, I use the free Virtualdub software to create 720p60 footage, and then import that into premiere for editing.

I trust the quality of the Vdub resizing algorithms, there is a "Smartdeinterlace" filter available that IMHO works better than the PPro deinterlacers, and its fast.

Here's the link to the filter:

Looks like you may need to use another program for this. No matter what I tried, PPro kept treating the two fields as one frame, which is technically correct but not what you want.

I know that After Effects can do this, though. It can treat individual fields as if they are frames.

How do you do it in AE?

Using the 'interpret footage' option. AFX's Help explains the details.

I just tried it now and it turned out to be pretty simple. I created a 1280 x 720 59.94 fps composition and loaded an ordinary DV AVI file (720 x 480 29.97 fps/60i). After Effects shows each field on each frame individually.

Keep in mind it has to interpolate the missing lines, so you end up with a shimmering effect as the interpolation alternates between frames. However, that's as good as you would expect for what you are trying to do. (It would take field blending to cover this, which is what you are trying to avoid.)

Interpreting 60i material as 60p is quite common in After Effects as it's the only way to manipulate the individual fields, sometimes needed for complex rotoscoping and retouching work.

A good 'bob' filter can virtually eliminate that shimmer ... there are several for AviSynth for example.

there are only 2 easy way to do this correctly.
1) you trade resolution for speed and you consider each frame as picture.
you got 1080i becomes 540p.
you can uprez to get get back 1080, but this would bring nothing more than what you get already (except more pixel) since doubling line is not really an improvement.
2) you keep resolution and trade for speed.
deinterlacing will get you 1080i60 to 1080p30.
you can interpolate to get back 60p, but the risk is getting artifact visible when looking at stills, because in this process you interpolate twice, at deinterlace and at frame picture doubling. For regular movie, i think it is the best workflow.

If your final product is a DVD or is displayed on Standard Definition device, solution 1 is the best.
if you need to keep it HD, the 2nd solution is better.

It is perfectly feasible to get good-quality 1080p60 using an appropriate 'smart" deinterlacer. Bright people have put considerable time into developing them.

If you don't consider this 'correct', then by all means stick with your preferred workflow.

I hadn't heard of these before, but you are quite right. From what I've read, a "bob" filter selectively chooses which parts of the image to interpolate or not based on movement. For example, if something is static in the background, it will combine the two fields rather than interpolate the missing lines, but if something is moving in the foreground, then various types of interpolation (some "smart", some rudimentary, depending on the filter) will fill in the missing lines.
