PAL DV to ProRes HQ Render changing pixel aspect

[Sascha Haber]

Hey Rohit, remember ?

Same Problem still persisting ?

My solution was to avoid the source files, render to DPX and set it all to square pixel.
So far Resolve is unable to treat field source (and or DV) material correctly.

Hey Sasha thanks for the response. Wow no fields in Resolve!? How do I go about “avoiding the source files?” Do I need to transcode all the clips to pro res from DV-PAL? Perhaps with compressor? Then do I loose all the color work I have done so far on this project?

If I render to DPX how do I get it all back into FCP? Perhaps render as Target and bake all the clips together then convert to pro res from DPX?

Thanks!!

What I did was consolidating my source clips, render to DPX in AE, rebuild the timeline in Resolve using the DPX files, do my grading work and then write ProRes from Resolve to use back in FCP.
I also was unable to write out a DV-Pal codec that Desktop Video understood…from Resolve…AE worked fine 😉

Wow that is quite the work around. The doc I am working on has 287 Clips. Pushing all that through AE sounds painful. Did you find another way to translate the files to DPX? It seems the AJA solution only like RGB files. Once you had your DPX files did you bring that into Resolve with an EDL generated from FCP? I have not had the best luck bringing EDLs into Resolve.

[Sascha Haber]

Well, today I would use Scratch if its a lot of media.
You can of course try a codec2codec solution in FCP.
The problem is the DV codec basically.
Glue tools renders DPX from FCP too.
Oh, I had a documentary with 1400 clips…
So stop whining and get to it…good luck 🙂

normally you would like to avoid fields all together to get “filmic” look.

I have not used fields like last 5 years and do not miss them.

Depending on your NLE you could get exported progressive material pretty easy i bet?

FCP has not been really good making progressive out of fields imo.

Thing is, you need the fields for a proper pull up or pull down conversion.
Also the Terranex does an amazing job if it has 24p to 29,97 “fake fields” and put em back to PAL.
So all i want is Resolve to be discreet and treat em as they come, not totally screwing it up.
Thats not the case right now.
I am not even talking about take em into the consideration for scaling.

Here is our process and If i did understand you very well 🙂

– duplicate the sequence in FCP ( pixel dvpal, 720×576, inférior, Apple prores )
– export the sequence
– import In Da vinci and use scène cut détection to create your EDL
– In média pool change the aspect pixel ratio to PAL or PAL 16/9 up to your case
– grading time
– render in prores with ” enable video field rendering ”
– re import in FCP:
– settings of your new sequence:
* change the frame from supérior to inférior
* change codec to DV pal
* pixel PAL or PAL 16/9

and normaly here you are 🙂

Cheers!

Thanks Bernard – when you say “supérior to inférior” you are speaking of fields correct? What is the upper field called? supérior or inférior ?

[Bernard James]

yes…sorry for my english! “supérior” is upper field 🙂
