Difference between Blackmagic NTSC Jpeg and 10 Bit Codecs
Hello everyone. I hope that everyone had a nice turkey day. I have a Blackmagic
extreme capture card and have often wondered the difference between capturing Analog SD beta tapes in eith NTSC-Jpeg or 10 bit codecs? Or even 8 bit for that matter?Now I have always been told that 10 bit is as good as it gets and that the BM NTSC Jpeg codec has a 2-1 compression ratio. However if I am capturing it from analog beta will the different codecs really make a difference in quality? Now I know the BM 10 bit files are the biggest in size and look good but I can’t even really tell a difference when comparing it to a BM NTSC Jpeg clip. And if you are cutting features for TV and there isn’t a noticable difference in the quality between the 2 codecs but it saves you space by working in BM NTSC Jpeg…is it the way to go? Am I assuming something wrong?
I have been told that working in a 10 bit sequence allows more of your effects to be real time and other features that a Jpeg sequence doesn’t offer but I haven’t noticed anything different to this point. Are there? I appreciate anyones thoughts on this subject.
Happy Holidays
