29.970 and 59.940 fps in the one project
Hi there I have a kodak sports camera .
The video files I got from it are :some of these:
1920×1080 29.970 fps H264 mov
but mostly these:
1280×720 59.940 fps H264 movI want to edit them into the one final movie.
Some of the 59.94 fps clips will be played at half speed for smooth slow motion.so my questions are what are the correct project settings and output format for highest visual quality and smooth play back ?
also how do I make some of the 59.94 fps clips half speed ?
this is driving me a little bonkers …cant seem to get it to look as smooth as the source .
Your help will be greatly appreciated.
thank you for reading -

Hey Luke!
You can alter the speed of a a clip in a couple of ways. You can stretch it, similar to the way you expand a clip, Hold CTRL and grab the end of the clip on the timeline and stretch it to your desired length. This will stretch the video so slow motion will be achieved. You can also do this to speed the footage up. The limit is 4x slower (0.25x original speed) and 4x faster.
If you want your stretched footage to be exactly half or exactly some other percentage value, you can Right Click on the clip on the timeline and go to Properties. You will see text boxes with ‘Playback Rate’ and ‘Undersample Rate’. Choose the ‘Playback Rate‘ box, and set the value to 0.5 for half speed.
If you want your 60 fps footage to be progressive normal speed 30 fps, you can make ‘Undersample rate’ 0.5, and it will skip every second frame.
Unfortunately I am not the king of output format knowledge, but I would probably have went with MPEG 2 for internet or AVI for uncompressed rawness, perhaps for exhibition. But I’m not sure, I’d ask someone else about formats.

Hi Daniel,
Thankyou for your response .
So I see there are multiple ways of slowing down an event.
I want to slow some of the clips to exactly 0.5 speed.
When I do this via the event properties the event slows down but it is the same length, because of this the new event does not play the entire clip (only half).How can I slow an event exactly half and see the entire clip play out ?

For any other people who happen to read this .
I still very much need to know what projects setting and output ?
what frame rate of the project and what res etc
thankyou 🙂 -
actually i kinda figured it out change the speed in properties to 0.5 then drag the event out until you see the little “cut” in it. after that “cut” point the clip starts to repeat or just display a freeze of the last frame (depends if you have loop on or off in properties)

Ah sorry I should’ve said.
The event will appear to be the same length but it will still be stretched, if that makes sense. You simply have to expand the event normally until you have the rest of it there.
Here’s your event before:

|——–| – – – – |So you grab the end of the event and expand it to get the other half, and you will get this:
|——————|and that will be exactly a 0.5 slowed down version of the original clip.
I hope that makes sense…
