RCX Quictime Export Problem

[tonydavis]

Hi,

I was working in an indian movie project as a dit and i was facing some problems while transcoding r3d footages of red epic into quicktime(h.264) for dailies and offline edits. I export my entire bin of footages with the colorspace as redcolor3 and gamma space as redgamma 3 , but the result i get is a kind of redlogfilm quicktime output which is not i want for the dailies stuff and i dont know why this glitch is happening....i tried several times on different mac's and i faced the same problem.....can you guys help me around with this to get a redcolor3 and redgamma ouput as we shot ?? ...i was using redcine x v.14 for transcoding.

Quicktime has gamma issues. Do some research into the various fixes to see if this applies to you. Here is an article, but it may be outdated. Search for more if these don't help.

How are you playing the output file? Try both quicktime and VLC and see if there is a difference. If both show the same thing then the problem is in the encoding process. In this case, try another encoder, like x264 which is far superior. You'll still need to use quicktime as a wrapper and therefore may run into gamma issues, but it may fix another problem.

For some earlier projects i had been using adobe media encoder for the transcoding process and i had no colorspace issues and gamma shifts,but transcoding in rcx was way faster so i moved on to it...but i think i have to test it with other codecs like prores...letme see....
