I'm currently working on a documentary which is being shot with Nikon D7000. I shoot all my footage in 1920*1080 24p (as there is no 25p option). And because I live in Europe I must adjust to European standards - which in case of broadcasting (and I decided to go full HD) are either 1920*1080 50i or 1920*1080 25p.
So, in order to fulfill the standards I must transcode my footage to 1920*1080 25p. My first attempt was to convert the footage (in VirtualDub) using one of the lossless codecs: Lagarith or HuffYUV but unfortunately the files turned out too heavy for Sony Vegas...so:
My question to you is this: What steps should I take in order to transcode my footage and maintain as much quality possible?
(Let me also add that the production house wants the final project in either Apple ProRes or AVID LE DNxHD. I do not work on MAC so ProRes is not an option. Anyway, my ideas are as follows:)
transcode to lagarith (in VirtualDub) -> then transcode to .AVI AVID LE DNxHD (in MPEG Streamclip) -> edit the footage in my target codec and render it to AVID LE DNxHD.
I would like to omit the first step in VirtualDub but I don't know any other good encoders capable of doing straight conversion to AVI/MOV AVID LE DNxHD. (I'm not interested in encoders converting to .MXF as Vegas won't read those). Some might suggest: well, transcode only in MPEG Streamclip! But unfortunately the results are not satisfying. The video isn't really changed, the frames are just doubled. So onto my second solution...
transcode the footage to Cineform -> edit in Cineform 25fps and render to .AVI AVID LE DNxHD in Vegas
This step seems the easiest but where do I save more quality guys? Or maybe there are BETTER options. I would be very glad if you helped me out. I'm willing of course to answer all your questions. Thank you! Peace!
