720P upconvert not cutting it

[Gary Adcock]

Bob
Lots of questions but not a lot of info.

First off– No It will never look right to transcode direct from NTSC (interlaced content) to 720p ( progressive content) without some sort of converter ie: Teranex / Alchemist
Try the 1080 29.97 DVCPROHD easy setup. your content is 29.97 so you are stuck with that frame rate unless you have access to a converter.

Questions on your process–
are you routing the serial( RS422) signal or are you connecting the decks straight to the Kona2

Are you converting the analog signal to SDI? if so How?

you must be running 10.3.9 if your running QT 7 have you updated to 7.01
Running the current AJA drivers?

Hi Gary,

Actually the interlaced content looks great going to 720P the Kona 2 is doing a good job with the image it’s just the timecode issue, yes we are running the latest drivers from Aja they even emailed me the new beta, the decks are configured from a router and locally as well. Running FCP 5.0.2 also QT 7.01 tried routing the SDI direct to the Kona and then also to through the i/o

As I said in the post we did try the 1080i setting DVC Pro HD it does fix the timecode issue

I did notice the file size of DVC Pro HD 1080i is the same or even slightly smaller,

Gary this is perfect for you….if we produce graphics 1080i (mostly after effects & lightwave) will the file sizes and renders be longer than 720P ?

I was told (at siggraph by Apple) not to render in the DVC Pro HD codec but to use the animation codec than transcode using QT ? Also my 3D lightwave guy is on a PC.

Thanks, Bob

I do a lot of work for 720p DVCPro HD in After Effects and I render everything to the native DVCPro HD codec. It’s incredibly clean and really looks great. Haven’t tried a 1080i render yet, but the 720 renders are about normal to most everything else I do. No longer, no shorter.

I know that Walter uses the DVCproHD codec but I do not necessarily build my graphics totally in another application so I too also use the animation codec. I love that fact that it gives me a smaller file size that the “none”compressor and I also get the alpha channels so I can modify things later if I need to. (and I may have been in that Apple conversation Bob)

Your 1080i60 file size and renders will be larger and longer than with 720p24.

Rendering in Lightwave on a PC use either animation(if you need to keep the alpha’s) or pjpeg @ 75% or better if you do not.

Thank you, We’ve done some tests and I think we are going for 1080i it seems to have a lot less bugs with the Kona 2 card
appreciate all the feedback and codec advice we’re going to need it !

Hi Gary,

My lightwave guy says he can’t find pjpeg (75%), he rendered psd uncompressed frames 1080ix1920 at 8 mb per frame and he’s freakin out, can you steer us in the right direction and point out the pjpeg

Thanks

your guy cannot find “photojpeg” ( whew!~)
then use PNG and Targa for still frames or export as an animation codec video stream
