Render out 50i from 50p

In Avid you must create 50i project and put your 50p footage on timeline, that's all. You get true motion between fields. Same Premiere (in Premiere sequence must be 50i).

Do exactly the same in EDIUS and Vegas. Start with an interlaced project and just apply the progressive clips. Optical Flow will create the extra frames for a slower frame rate but it is not always acceptable and to me most of the time unacceptable. You need to match sample rate NOT timecode. Same number of frames as fields.

That's the last answer I got from the support one week ago.

"Please be advised that after following up with our development team, I believe that in order to render out an i50 clip from Resolve you would need to render from a 25fps timeline with the 'Field Rendering' option enabled.
Whilst I cannot comment on the exact way in which Resolve performs its processing, I believe that the behaviour you are seeing when rendering out to this format is to be expected"

But this doesn't work and I get no more answers when I ask again..
For me, rendering out 25i and getting 25p is nothing "to be expected"

Doesn't work for me. I make a 25 fps timeline, enable video field processing and drop a 50p clip into it.
Rendering with field rendering active results in a clip that shows as interlaced, upper first in MediaInfo, but it's clearly not interlaced.

Because Resolve have no support for interlace project/sequences at all.

Yeah, that horse has long been dead and beaten...

There is no automatic correlation between checking the "field processing" in timeline settings and adding the interlace flag in output (for those formats in deliver tab that support it - regular h.264 don't)...

All that "field processing" does is apply effects to even and odd lines separately in order not to destroy the original source's line-interleaved content. That's why the Fusion workaround must be done on the finished cut with all effects already applied and added as nested timeline or compound clip in a separate timeline ...

Because Resolve have no support for interlace project/sequences at all.

Yep, its interlaced support is just a partial hack not a proper one.

That's what I did.
And I got 25 PsF on export.

You basically drop 50p source into 50i project. That's it. Maybe your source was 25p not 50p.

It works in every NLE, except Resolve.

Oh no. I will switch back to AVID. Even MC first ist able to export 50i. Its a pity that I had to spend 300 for Resolve Studio.

I have the same problem. I have Fs7 interlaced footage and I have bunch of drone footage in 50p, and I cannot transcode to 50i in editor like in Avid or any other NLE. And there is no fields generated for transforms in Resolve. Any graphic I'd like to zoom I must switch to after effects. Any footage conversion from 50p to 50i I must swich to AE or Avid. This slowing down my workflow. I wish there will be proper support for interlace.

DaVinci can create 25i fps from 50p fps. Read this thread better.

Using Fusion is just a workaround, not a real solution.

I have used the fusion workaround and I do get an export that seems to be proper field render 50i (although I don't have a broadcast monitor to check the fields), but I used a 25p video file, not a 50p.

The only thing that concerns me is that on the cut you can see the fields of both clips (like a one frame dissolve).

Hey,

If you're on mac, check what the old but efficient app "JES Deinterlacer" does for free...
Yeah, 32 bits only, but, does the right thing the right way it has to...
