Thanks Jay!

I did check Creative Cow, but neglected the official Avid forums.

Re: [Avid-L2] Recoding DV tapes #OffTopic

Here's my 2c input: 

In my mind any interlaced format is now both completely obsolete and highly vulnerable - and for archiving, keeping it interlaced means you trust that the future will be able to both interpret and treat it correctly. I've seen enough bad cases over the last 20 years to say with some conviction that the future does not deserve that trust. Neither students nor equipment understands issues like interleaving or non-square pixels any longer. 

Given that i25 was a horrible compromise to begin with, expanding it to p50 makes perfect sense for future preservation. You're not loosing any information, all the original pixels are still there, you're just giving it a safer cushion to rest on. And I would say the same for scaling everything to square pixels.

Re: [Avid-L2] User Profiles

Hi,

I don't know how Media Composer SubCap Fonts, for example, will work when switching between Mac and PC.

Windows 10 pull it from C:\Users\<WindowsLoginUserName>\AppData\Local\Microsoft\Windows\Fonts.

Best,

Ofer Raveh

For the sharing videos you can also use Handbrake.

You can enter FFMPEG command line in the GUI but you could probably just scale to 704x576 'stretch' (thus your rectangular pixels become square?) and also use 2x YADIF deinterlace under advanced to get 50P, if you want to keep the temporal motion?

Others will have better shutter encoder / ffmpeg knowledge...

Re: [Avid-L2] Recoding DV tapes #OffTopic

How do you plan on distributing it to your family members. I have used private password protected uploads to my vimeo account and they can watch or download from there. Another option might be dropbox. Or if you want to give them physical media you could burn dvd's or give them thumb drives.

Why? Storage is cheap!  Archive the files as DV, which means you are losing nothing. You can always follow Job's advice and upres later. 

I have been shocked at how decent some early and ugly 8mm Sony video looked when digitized to DV using a Digital-8 player and then de-interlaced and up-rezzed and graded and noise-reduced in Resolve studio. 

A painfully long (unedited) example can be found here.  

Tech notes there too.

Re: [Avid-L2] Recoding DV tapes #OffTopic

What JBeck said.

Storage cost is irrelevant nowadays, at least when talking DV-PAL (or DV-NTSC for that matter). (Roughly) 25MBit (DV25)+ Audio (uncompressed) vs 1/5 of that in H.264 is not worth the trade-off in quality, imho.

704 is the correct width for DV-PAL, the missing 2*8 to 720 were for left/right digital blanking.

For 768 vs 720 (704) there is a good chart here:

https://en.wikipedia.org/wiki/Display_resolution#Common_display_resolutions

Me, I personally wouldn't deal for now with the specifics as long as I can digitize the original media in a "1:1" manner, that is: with no alterations. Everything else can be done from here, no need to compress or alter an already (from today's perspective) already flawed source material for the sole purpose of posterity. If the posterity will touch it, let them deal with it, in any aspect. But for the estate, you would take a polaroid of your family's pictures, trash them originals and leave the polas, would you?

Hello all. I'm digitising a load of old family PAL mini DV tapes using iMovie 10.0.5 on High Sierra 10.13.6 on my trusty Mac Pro 5,1 via Firewire, the beauty being that iMovie records continuously, but breaks each original clip into a new file and gives it the title e.g. 2007-08-16 15_52_43.mov - and as a person who loves accuracy and detail, this gives me great joy and delight.

However, as DV is quite old school, I fancy making the files a lot smaller using the newer h.264 codec at around 3 - 5mbps, BUT I am conscious that PAL DV is 720 x 576 with non-square pixels, but only 704? horizontal pixels are visible. BTW these files are just for posterity, not for future editing.

So, my question is, should I simply re-encode using h264 and keep all dimensions & pixel aspect ratio the same as per the DV PAL 601 standard? My only worry with this approach is that with future technology, the ability to interpret the rectangular pixel shape might fall by the wayside as time marches on.

The other option is this: should I try to wrangle the footage into pure 4:3 shape e.g. 768 x 576 with square pixels so that it will always display correctly? But then of course, there is the issue of 704 visible pixels, so presumably this will leave a small black pillarbox?

I have Adobe Media Encoder and I am also just trying out Shutter Encoder, although I can't find any reference to 'pixel aspect ratio' in the latter.

Two more things: Should I map to 0-255 levels? And, should I de-interlace? Oh learned ones, what settings would you use?

Thanks so much for any helpful advice!

Re: [Avid-L2] Recoding DV tapes #OffTopic

I'd definitely keep the DV captures. I think I'd then bring them into an HD project and transcode them to ProRes. Perhaps you could bring them into a 50p project for 'deinterlacing'. The blowup to HD (even if just 720p50) ensures you bring everything into the square pixel world, and you can easily export to H264 or H265 from there – and in my experience, blowups to HD yield better results when you upload stuff to YouTube and such. My 2 cts.
