Question

Premiere seems to step on original video's quality

I've come to notice this recently due to a client who has videos shot on some type of Canon handycam...

 

the orginal .MTS files are 29.97 fps, however they have that hyperreal motion look when played back (outside of premiere), the motion synonymous with old 30 fps interlaced footage and also similar to 60 fps progressive... well here I can see that quality in the 29.97 footage outside of premiere... however once brought into premiere and exported, the footage looses that quality and looks like more like what most 30 or 24 fps progressive motion looks like. This at one point would seem like an asset, however I would like to know why this happens... I'd like to be able to control this and possibly export the video LOOKING the way the original hyper real motion footage looks. 

 

The gopro footage I typically edit these days uses HEVC (I think) codec... that looks the same in the browser and in and then out of premiere....

 

These canon handycams use AVC HD codec... not sure if that going into premiere looses some type of quality in the motion, if it does I don't know what setting to change to get the original motion quality back.

 

Anyone have experiance with this or know how to perserve that original motion if so deseired?

It looks like you've determined the footage is interlaced from the posts and responses here. And some good advice from mgrenadier and warren. I *have* to work in interlaced HD sequences all the time, even if the footage is originally progressive as in the TV broadcast environment 'interlaced' is still the broadcast standard for HD. And the only way to properly monitor interlaced sequences is as Warren suggest - video hardware from AJA, Blackmagic Design etc connected to a 'proper' video/tv monitor.

But to solve your problem in the future - check to see if the Canon handycam your clients use can shoot progressive instead of interlaced. It might well be that it can - after going through it's internal settings.

I'm having a flashback to the mid-2010s when I had three overlapping projects where one required straight-forward i29.97, the other p59.94 for an import into Quantel for "frames as fields", and the other as i60 with 3:2 pulldown.

 

And I wish I could have $5 for every interlaced delivery where someone who has never seen combing before sends out a panic-ridden email to everyone on the team about a "huge problem with the delivery".

    Is it possible that the footage from this particular camera was shot 'interlaced'??

    If it was and you want to keep the interlacing - you would need to ensure you are working in a 29.97 sequence with fields set to upper or lower field first (upper of it's HD footage). 

    In your bin, right clip one of the canon clips and select 'Modify', then 'Interpret footage' and see how Premiere Pro is interpreting the fields under 'Field order'. Whatever field (or not) that is should be the setting for your sequence.

    I don't know if it is... it's 1080 HD footage... but I don't know if it has some kind of  HD interlacing (like 1080 30i i guess???) I don't know how to check that either... i don't know the camera and I don't know where to see that in the meta data either

    well the clips are upper feild first by default, I switched a duplicate of the timeline to upper field first to see if that produced a result. Nope... that's not it.
