1080 60i meets 720 30p ....ideas?

Yoyodyne wrote on 6/14/2006, 5:37 PM

I've got a project that is going to be a mix of 1080 60i HDV from a Z1 and 720 30p HDV from a JVC HD100. I'm not sure what to set the project up as. My sense is to go with 720 30p because the 1080 60i should convert to progressive o.k. - it looks good on my Dell 2405 as 30p - and I think I will be working with a bit more 720p footage than the 1080i stuff.

Any tips or ideas? Anybody had any experience doing this?

You can check my 720 test thread the other day. I'm impressed with the format. Still toying around with Spot's deinterlacing recommendation, it is detailed in his Vegas 5 Editing Workshop book I have.

If you are a CineForm Connect HD 3.0.3 user you convert to either format to the other during capture/conversion. Converting 1080i60 to 720p30 looks very nice. Then editing 720p30 is a lot easy on your NLE (and the quality is still excellent.)

Do you mean the part where it says to duplicate the track and set the media on one to upper field first, and the other to lower field first, and then mix them? I tried that but found that if I change one track to upper/lower the other follows suit and they are both identical.

I am probably missing something simple and stupid. Please let me know what it is...

Thanks for all the tips guys! Have been using Connect HD with great success and am just upgrading (for free - thanks guys) to Version 3. All the 60i footage is already captured but I might just re-capture it just for the 60i to 30p conversion. Nothing is edited yet. Also thanks a bunch Dan for all your help and support!

fldave, thanks a bunch for posting your test stuff. Very interesting, I'm always amazed at how much you can mess with HD footage and still get good results. I hate to say it but I think Iike the 24p clip the best - I have no rational explanation why :)

Jayster, ah the wonders of nested veg in Vegas 6! Created a copy of the veg, called it Lower, and set project properties to lower, clip properties to lower.

Imported Lower veg into original veg, placed on timeline 2 underneath upper field first timeline. Set timeline 1 to 50% opacity.

I didn't see a large difference initially, haven't had a chance to study it closely yet. The book says to set the Project Properties to Progressive also, but my original footage was generated with Upper first. That's what I'm experimenting with now.

I would highly recommend recapturing the footage with ConnectHD 3.03. In addition to the deinterlacing options, the captured footage previews noticably more efficiently.

I noticed flDave you captured at the norm. m2t straight 60i correct then rendered as 720p etc.. Correct?
how does this compare to converrting to 720p in Cineform
Has anyone tried this?
I am thinking for output to SD DVD that this could also give excelent results as does the HDV 60i projects do to DVD.
Then I am still confused on the tabs in the "Pref" area.
In precompression you would select:
the resize to 1280x720
check the deinterlace 1080i source, right
Do you then also select the "progressive" button in the encoder options? or is this not nesc. with the deinterlace selected.

epirb-
Captured m2t from fx1 with Vegas. Created Cineform avi from standard vegas timeline. Built Veg timeline with Cineform to identify/trim the clips. Project Properties were HDV 1080i upper field first. Replaced avi with original m2t. So no Connect HD involved.

I used the wmv format only for this testing, which is native progressive. Selected "6 Mbps HD 720-30p Video" template. Manually set the Rate settings to what I wanted and overrided default constant bitrate and set to 3MB.

As I said, I haven't gotten Connect HD yet. All of the above was out of the box Vegas.

If by chance you don't want to buy ConnectHD (and I highly recommend that you do), you should install the demo. After you uninstall the demo, the codec will still be updated and the updated codec is way better.

Also give the trial a go, it is free for 15-day, and yes you get to keep the new codec.

David and Laurence, Yes, upgrading the codec is on my to-do after a short vacation. That is very generous of CineForm to provide these free upgrades. And yes, CineForm is also on my "Things to Buy" list, which unfortunately is rather large right now, but the new version sounds wonderful.

Unless you don't have a camera or a decent mic, move it to the top of your list. When you use it you'll see why.

Thanks Laurence.
