100fps / 120fps .mp4 No Lag Editing Workflow?

[Guest]

Hello,

I shoot 100fps / 120fps (.mp4) video on my Sony A7sii. I would like to know how I can transcode this video to 100fps / 120fps in Adobe Media Encoder cc 2018 for smoother playback in Adobe Premiere cc 2018?

Selecting Pro Res in Media Encoder will only allow me to transcode footage up to 60fps and not to 100fps or 120fps? Is there another codec that I could use inside of Media Encoder?

When I put 100fps .mp4 video into Adobe Premiere CC 2018 my program lags. How can I stop Premiere from lagging?

Thank you

Have you tried interpreting your footage before bringing it into your sequence? Interpret your footage at your desired frame rate, then create a new sequence from the interpreted footage.

I am a bit confused as to your response. I don't need to interpret my footage as I want the footage to remain as 100fps when I import it into Adobe Premiere. Rather I would like to convert the footage to another format / codec as 100fps to stop my program from lagging and Adobe Media Encoder won't allow me to do this.

I imagine you shot high frame rate because you want to slow it down, correct? There's no need to edit in 100fps. I like to edit at the frame rate I'm going to do my final export in. So I typically interpret my footage to that speed.

I would like to both edit my footage in real time and edit my footage as slow motion.

You can always interpret your footage then speed it up (to normal speed) later. Give that a try and see if it resolves your lag issue.

Your PC specs may also be a contributing factor.

Here is my current solution to reduce lag with slow motion video. In media encoder I create a custom proxy preset. Here is my proxy preset: Jpeg, Match Source 100fps, resolution 640x360 (360p). Then I import my 100fps or 120fps footage into premiere and then select all the clips, right click on the clips, then choose create proxy, then I just select the custom proxy preset that I created in media encoder.

Why do you want to re-encode at 120fps?

I want the footage to play back in real time. Real time is 100fps / 120fps. Adobe doesn't support converting or playing back footage at 100fps. All footage must be played back at 25fps or 50fps which makes all the footage slow motion. I want to choose between playing back the footage in real time and playing back the footage in slow motion. And when I create a proxy which is not 100fps then I am stuck.

Hi Andrew,

Please provide us your monitors specs as even if you are getting 120fps you are still seeing 60fps because your monitor can't display higher if it has 60Hz refresh rate. So, due to this fact you might see it laggy, dropping frames etc.

I found some 100fps footage to test with.

So by interpreting the footage at 25fps and bringing into a 25fps sequence, I was able to play it back in slo-mo or add a 400% speed to play it back in real time. No lag.
