A question about converting my old PAL DV movies into digital
Hi all, I’m a bit of a newbie here and I’m hoping someone may be able to help me in my latest venture.
I have a load of old family videos which I really want to digitise and upload to YouTube for the family for a special Christmas surprise!
I’ve already done the most painful bit, and captured all of the footage onto my PC: Sony DV Handycam->Firewire->PC. Now my 2TB HDD is short on space for the first time ever ?Digression aside, each of the ‘raw’ avi files are huge, with properties of 720×576 @ 25fps. I’m using Premiere Pro CC 2017 and have been encoding to HEVC (H.265).
Here’s the issue (and I’ve spent a while researching prior to asking this) what’s the deal with the frame rate on export? It doesn’t look right at all. What I’ve learned is that the raw footage from my DV camcorder is interlaced and the top and bottom fields have been compressed into a single frame when I export? In Handbrake for example there’s a ‘bob & weave’ export facility which on compression looks pretty much 1:1 with the original and ends up at 50fps. I don’t however see such an option in Premiere Pro. I can change the framerate to 50 fps on export but I don’t think it’s doing what I want it to do.
Does anyone have a tried and tested method of exporting the classic DV goodness from it’s avi original into a compressed, clean mp4 (or similar) output directly from PP? Many thanks all ?
As a side note, the raw avi shows these properties (don’t know if they are of any use)
Cheers, Jon

handbrake changes 2 fields to 2 frames so converting 25 interlaced to 50 progressive
that is one way to deinterlace called “bob and weave”.does your video exporting have lines when there is fast motion?
match your sequence frame rate to the 25 or…
enable optical flow or you’ll get duplicate frames if you mismatch framerateI know in after effects, if you place a 25i into a 50p comp, it will fill
each frame with a field so you keep the smooth high rate motion effect.if you deinterlace, it will become motion movie-like at 25p.
In adobe media encoder right click interpret field order as lower field.
then output codec video tab as progressive.I don’t believe premiere can do bob and weave export. Someone can hopefully correct me if I’m wrong on this.

Dont mess with the fields. PAL dv is LOWER.
DV avi files are about 13 gig an hour which is the normal size. (get a larger disk)
If you want to make dv footage suitable for Youtube.
Make sure you have a matching sequence (there is a DV preset for this).
Export to H.265/H.264/mp4 (progessive) making the framesize 788×576 par 1.0 en framerate 25 fps. (widescreen is 1050×576)———————————————–

Thanks all.
Chris:
Yes there are exporting lines that appear! I’m slightly confused – what’s Adobe media encoder? Is that essentially the screenshot below? All I want to achieve is on compression, the same great fluidity that the raw avi provides.Ann:
Perhaps I’m being stupid, but if I select match sequence settings, there’s no option for compression below (it’s all greyed out).
Ignore the YouTube bit, that’s something I’ll do later down the line. For now, I want a nicely compressed MP4, retaining the extra-fluid nature of the original.

i anticipated that you had this error.
here’s where to interpret footage and render progressive
https://www.youtube.com/watch?v=eyz-87Uszekas for keeping the video look, you have two choices. uses optical flow as listed below for 50p
Time interpolation settings using optical flow which might introduce artifacts
https://helpx.adobe.com/media-encoder/using/export-settings-reference.htmlor try after effects with placing 25i (interpret fields lower) into a 50p composition and render out 50p no fields.(will put one field in each frames, ie. frame double

Thank you. I’ll try the first option as I’ve never used AE before and I want to minimise my learning for now ? I’ll let you know how it goes!

Nailed it – I think.
The HVEC 265 encoder has no option for lower/upper field. When I reverted to H264 the option was available!
I wonder why it doesn’t support it in the former…
Thanks again all 🙂

If exporting to H.264, you do not want any interlacing (fields). The .mp4 files will be watched on computers and tablets and their displays are always progressive, so you want to export Progressive.
Thanks

Thanks – so for clarification, that’s basically choosing “lower” in the render bit? That’s effectively deinterlacing it right? (Sorry if I’m a bit naive, this is all new to me).
-
No, if you choose UPPER or LOWER, that is INTERLACED video. You want Fields = PROGRESSIVE.
You could just select the H.264 > PAL DV export preset, then manually change Field Order to Progressive.
Thanks
Jeff

Perfecto! I’ll give that a bash tonight, thanks Jeff.
