I'm all about making informed decisions, but I personally think PD should not display the warning for 29.97/30 and 59.94/60fps differences because there's nothing that the user can do. I think it should always display the warning when you add any clips to the timeline that are significantly different, like 24, 25, 30 or 50fps when the project settings are 60.
Not sure why your view nothing the user can do, can you expand, give a timeline or step procedure example to replicate?
Again, it's a warning for user caution, do as you wish with it. However, if one has true 30fps video on the timeline and you create a custom profile at 30fps, you will not drop or add a single frame. Thanks PD for prompting me my timeline footage is a little special and maybe I want to validate what I'm doing. For proof I've copied 6 duplicates of the 30fps_Custom.m2ts file I showed and created in the pdf writeup. I used 6 duplicates in the timeline to simply get the number of frames up so we are not talking a one or two frame delta. This 30fps clip had 2042 frames as documented in the pdf (bottom of page 3), 6*2042=12252 frames in my new timeline. As seen in attached pic, if I produce with a true 30fps custom profile, I have not added or dropped a single frame, I get exactly 12252 frames in the newly produced file and at 30fps. So, 30fps source, 30fps output. I can and did do something about it.
On the other hand, since my timeline has true 30fps source footage in it and if I elect to ignore the message and simply proceed to produce and use a default profile, you see in the same pic I only have 12240 frames, since the default profiles playback is slower, 29.97fps, PD needed to remove frames since the source was 30fps, 12252*29.97/30=12240, a exact match to the frames in the file produced by PD. So, 30fps source, ignore warning and accept default produce profiles, 12 dropped frames. Are these deleted frames critical, someplace perhaps yes because if I wanted to countdown from 10 in that area, I didn't, a title with a countdown number on it was deleted.
Again, it's a simple valid warning, if I set in pref NTSC30, PD is simply cautioning that everything downstream for default settings in PD will create a 29.97fps output unless the user adhears to the caution and does something. It's a basic warning so you the user can do as you wish to produce a masterpiece. In this day and age should one have an invariant timeline setting, maybe, but we are working with the PD we have.
