720P60 23.98fps (960×720) > HD Layoff to tape 1920×1080 (59.94 fields / 29.97 fps)

[Lisa Rolley]

SO its finally time to layoff to HDCAM and when bringing the render from AE back to FCP and rendering fro Animation to 8bit uncompressed on the fcp timeline…i have done a few tests and the stuttering is still there.

ANy ideas???

I have to layoff by EOD and iam beginning to freak out here, i followed the instructions you all gave me but this problem is now only visible on the NTSC monitor – I had not seen this up to this point because i was looking at a computer monitor.

Thanks

Playback in FCP with 8bit uncompressed sent to a NTSC monitor in realtime requires a lot. Are you talking about the HDCAM preview or a realtime uncompressed FCP preview?

[Lisa Rolley]

yes we have a fibre-channel connection andh ave been able to play back real time…still cannot figure out this issue – the jitters wont go away!
any other thoughts or suggestions?

It could be so many different things! You say an NTSC monitor… You are working in hd not NTSC. Have u not been working with an external monitor? Does your timeline playback jitter as well? Could be rt settings in your nle or maybe a reference issue…

New dilema: Now i need to then take that converted file and make it ltrbx D1 for dvdsp DVD encoding. What would that process be in AE if I had to use the 1080i converted file to go to SD DVD?

thanks for your advice

do a search on this forum for downconverting HD footage to SD and you should find your answer pretty quickly

Hey guys thanks for the responses : )

I actually have to ltrbx it first because the client has had issues viewing the 16×9 dvdsp projects – the place i am at also does this for anythign that is not 4×3 – everything is ltrbxed first then encoded for dvd.

I am just curious how to take the HD quicktime i made in AE and change it to SD ltrbx for proper playback – the tests i have done have looked jittery on dvd player playback so i think i might be doing something wrong in AE. _if anyone could explain the process i would really appreciate the help: ).

I will also post the question as an ew topic after doing a search.

thanks

How long is your footage.
Here’s what I would do.

Downconvert your footage. (No AJA Card?, you have an HDSR deck that can do the downconversion for you, with letterboxing. It will be a much cleaner conversion that AE will do.)
This is assuming you have an SD deck to dub to.

Then recapture.

Hey Joey

thanks for the response – so i have blackmagic card available and yes i could i ntheory do the dub workflow BUT the decks are being used and so they want us to try to use AE to do this – are there specific reasons why i should not try to do this – will it always look jitter yand messed up – apparently they normally use AE to go from 1080i to SD ltrbx.

Should’nt i be able to do this normally – and is the problem based on the fact that it started as 720p60 and THEN was converted to 1080i?

thank you for your time : )

Specific reason = AE is not a video converter.

Can it do this for you, yes, but it won’t be as clean as the other route.
You can nest your 1080i 29.97 (59.94) comp into an NTSC D1 comp and scale your footage to fit, but it won’t look as nice than if you use the proper tools to do this. I will get jumped on by others for saying so but I’m sticking with it.

And going from 720 to 1080 doesn’t help either. You are blowing up your picture quite a bit during that process.

Best,
Joey

oh, you should be able to do this in your NLE as well if you want to try. the percentage to scale from 16×9 to letterbox is 33% on the y-axis.
