Can't change frame rate in export?

I'm trying to export a video.  It will not let me change the frame rate - its set at 50 and greyed out.  Im trying to change to 30 because, for some reason, a 50 frame rate will not play on my Smart TV.  Another video I was able to change the frame rate, but not this one.  What am I doing wrong?  What are the best settings for exporting?  I'm new to this program.

Great, thanks. Finally, since most all of my footage is shot at 50 fps and only one clip at 59.94, should I still use 59.94 as the highest rate as you suggested before, or drop to 50?

I wrote about that earlier:

"It do also depends on how much of each footage there is. It may not be worth it if you have let´s say ten seconds of 59.94 footage and two hours of 50 fps footage. If that´s the case i would choose a 50 fps timeline to edit in."

 

So since that seems to be the case for you a 50 fps timeline may be worth it, but i write "may" since the 29.97 fps footage will cause issues since 50 is cannot be even divided to 29.97 while 59.94 can. It all depends of how much time of each footage there is. Trial and error til you find the best solution. Mixing frame rates boils down to compromises. "If i do X, this happens but if i do Y that happens but i cannot do both..."

 

This is why i always aim to use the highest framerate of the footage since i dislike dropped frames and stuttery footage. (trial end error once again...)

 

If you use a 50 fps timeline, export to 25 fps for your TV but expect seeing dropped frames in the 29.97 footage.

Please use PPro the way it is intended: as a non-linear editor that allows you to edit/change footage and then export the results in the desired format.

 

1. Import your footage inside a PPro project

2. Create a new sequence that will match however you want your export to be (in this case 30 fps)

 

Next, either of these options:

 

3a. Use context menu on clip in the Project panel and select Interpret Footage to adjust how PPro will handle this clip on a timeline. In this case you want to interpret the footage as 30 fps (or 29,97?). When added to the timeline, the clip will playback in slow motion.

 

3b. Add the clip as is (50/60 fps) to the timeline and let PPro conform it to the sequence settings (not the best choice, IMHO). The export will not play back in slow motion.

 

3c. Add the clip as is (50/60 fps) to the timeline and use a speed change option (context menu Speed/Duration) and adjust the speed. The clip will playback at the indicated speed.

 

Hope this helps.

Richard,

Yes this helps, thanks.  Not sure I know how to do this but I will work it through. You are suggesting this to end up with a 29.97 render? To address my concern about the TV, as opposed to social media, is that right?  I dont think I want to have anything in slow mo at this point so maybe I need to use your 3b method?

However, if I DO want some of clips in slo mo, but not all, how can I do that so that it wont muddy up hte audio also by slowing it down?

You are probably trying to export to a format/codec that for some reason stops you from doing some changes. If you write back your export settings here it´s easier to help since it´s hard to guess what you use today.

 

In short there are no "best settings" for exporting. If you edit 4K and export 4K it´s the best one if you want 4K. If you need 1080p  right away, exporting to 4K is one of the least wanted settings. So, what you export to depends on were the export will be used, almost always.

 

The reason behind your smart TV don´t playback 50 fps can be due to that the TV is too old or simply that you have exported to a format/codec that the TV don´t support. Consult the manual for the TV to find out the supported formats/codecs and supported frame rates for the TV.

Thank you.  I'm so new to this that I don't even know when or why I want to use 4k, or 1080.... but I'm learning slowly.  My video is of a flock of thousands of snow geese flying very close to me and fast.  When I play it, the birds are blurred by fast motion.  Thats to be expected.  I shot it at 60 fps in my camera and am trying to figure out how to render it to play with the leaset motion blur possible.

As for my TV, yes, it may be because its older and it only seems to be able to play at 30 fps.  But I also want to play it, and share it, for viewing on a PC, so am thinking that I should do that at 50 fps or some ohter rate when rendering?

You should start with using a timeline that matches your footage. On the screen dump you provided the timeline is set to 29.97 and you are exporting to 60 fps. Placing 60 fps footage on a 29.97 fps timeline and then exporting to 60 fps will look bad. Any mismatch will look bad. Your source footage was 60 fps, right? Or was it 59.94?

 

And, 60 fps or 59.94 fps is never interlaced.

 

If you want 29.97 interlaced footage to use on your TV, use the setting below after you changed your timeline to match your footage.

 

Premiere Pro is not so smart that one can use any settings randomly and then expect the export to automagically understand how things should be. So creating timeline with correct settings from the start is King. 🙂

 

 


OK, well, I see a good part of the problem.  Remember, this is the first time I've tried this, and was also the first time I shot video with my camera.  So, looking at my original clips, they are at different frame rates for some reason (the operator obviously).  Some are 59.94, some are at 50, some at 29.97.  So I'm all messed up and need to deal with my camera settings.  That said, what can I do to get the best I can out of this? Exporting for the TV is not the most important consideration for me, more so concerned about posting on social media.

And thanks for that screenshot, that helps a lot - and thanks for your patience too!
