    I’ll be capturing Beta through Firewire in FCP for chroma keying and was wondering what is the best codec to use. Tests with DV resulted in unacceptable footage.

    Out of curiosity how are you capturing Beta thru FW? What hardware does that? Is it a Beta deck that uses Firewire? Because the hardware sometimes determines what codec is to be used. Most firewire solutions use DV. But there are some that simply use it for communication like the AJA IO. But in both cases the Codec is defined for you. DV in most and the Codec used with the I/O.

    If the stream itself maybe compressed already giving you substandard results. Furthermore what hardware are you viewing it out of? If you are using a Decklink for example you would want your material in Black Magic codec. If you really can pick any codec, obviously use an “uncompressed” codec like Black Magic, the internal Quicktime uncompressed codecs like Animation or some of the newer ones. However if you are just going to stick in the AE world from here on out, you might as well use an RGB codec like Animation.

    Well, the reason I’m capturing that way is the Master Control room records to Beta and then feeds it to my router across the office. I then patch through my Sony DV deck which gets to FCP through FireWire. Cumbersome. ut thats the only way I can do it unless I pull the ole M100s out of the closet. (Not Likely). So, would capturing with Animation or DVC50 produce superior results or would they be negated with FW?

    Since you are going through a DV format you have degraded the image quite a bit so you might as well capture it in a DV format since it was converted that way anyways. If you are going to convert that video between apps a lot then use an uncompressed codec like Animation as much as possible.

    But more importantly, I wouldn’t destroy the image by converting to DV in the first place. Decklink cards are very cheap these days for great uncompressed 10 bit video.
