digitbeta (SD) capture problems!
hey guys! have a weird problem … let me tell you the story:
we are using a sony DVW-500 deck and a blackmagic decklink HD card and we are usually capturing with the following settings:
CAPTURE PRESETS
digitizer: blackmagic ntsc/pal
input: blackmagic ntsc/pal – 8 bit
compressor: blackmagic 8 bit (2Vuy)
fps 29.97after capturing the footage is interlaced altough on the tape its progressive … this is driving me nuts … and yes … i checked the sequences settings a million times without any difference …
would appreciate any kind of help!
thanks very much!

You’re certain it’s progressive on the Digibeta? That would be highly unusual to say the least.

Digibetas were designed well before progressive video. I wouldn’t know what to do with a progressive signal.

allright guys! i got you … the footage is interlaced on a digitbeta tape … but the footage was first shot on film and then transfered to digibeta … so the two interlaced fields should match one frame … but when i capure it some of fields get mixed up and i get the “interlaced look” partly (some of the frames look good) … so what should i do?
thanks

Ah! You see it helps if you give us all the details up front so that we can intelligently answer the questions. What you are seeing is the 3:2 added pulldown field. You said in your last update that this was shot on film and then telecined to tape. Well that explains it. In order to get 24 frames of film onto 30 frames of video you have to add fields. This is quite normal and the standard way in which all movies are transfered to film. If you would like to edit with the original 24 frames that corresponds 1:1 with the film then you need to do a reverse telecine process on your footage. You can achieve this with CinemaTools, or directly within FCP now (via CT). Otherwise, what you are seeing is normal for film to video transfers.
