Even though I discovered your channel in the last year, I love how I am still discovering some of your older content and learning. I had no idea about the optical flow and exactly what I was looking for. I was downloading software and looking for something that was right under my nose. Thank you Colin!

You just saved my life, again, after days of wondering what on earth was going on with the artifacts. I had turned on Optical Flow due to a different tutorial on the Adobe site that said to turn it on for best results. LOL. I turned it off and everything worked great again. Thank you sir. I am going to watch ALL of your PP and AE tutorials this week--you make it all make sense.

hi Collin. if i have 240Fps file and wanna make a slow motion clip. can i just use Speed and Duration or do i have to do it in another way? and if i use a 50p sequence how much would i need to set the speed to without getting a lag. thank you.

Greetings Colin! Another great video! I have a tech question for you. Hope it's ok if I ask on here. When I transfer screen capture video from my S8+ (Using Mobizen) to my computer, it changes the frame rate. I record at 30fps, but when I view the properties on my computer, the frame rate has changed to some random number. And when I import it into PP, the audio does not sync with the video, and it's always a different frame rate. It's never the same. Any help would be greatly appreciated!

Trying to determine if Interpreting footage is a redundant feature if changing the speed uses the same tech? In other words, when you create slow-motion by reducing the speed and you use the appropriate math for doing so, is it doing the same thing as interpreting footage? Or, is changing the speed always using frame sampling and thus you get, technically, a better image from using interpret footage? In other words, outside of preferred workflow, is there a technical difference between changing speed using interpret footage vs using the speed/duration option? I feel like "back in the day" of conforming footage vs changing the speed percentage in FCP, the two methods affected the image differently. Maybe that has been taken care of? Said most simply by another commenter on another thread, "is there any visible benefit to using the interpret footage method versus the speed/duration? or is it just a time-saving method?" Thanks!

Colin, your videos are very informative and to the point. Thank you.

you made it all clear for me thanks for this awesome tutorial You got a new subscribe, keep it up

Thank you very much! I've been getting frustrated working with 300fps render footage only to find that the 60fps export jitters when any motion is present. Frame sampling had been selected by default, but the result from frame blending is so much more smooth with my footage, I love it.

Thanks for the tutorial !! It really helps me when i shoot with 60fps and 24fps at the other DSLR cam..

You are great at explaining all of this. Thanks!

Thank you very much!! It was a very good explanation!

Great video as always!

thank you ! really cool

Thank you so much

Thank you, I love your videos. Learnt a lot, but... What if you RATE STRETCH it? What is the best render setting when you speed ramp something so it looks smoother?

Another excellent video,

Really clear and useful. I'd like to know how I can add extra frames to a photo burst. E.g. I've got a photo burst but it isn't as smooth as a video when animated. So can I use optical flow to create the extra frames?

thank you, great explanation my video output is 1080 50i and all my clips is from 3ds max and rendered as progressive as 1080p for time rendering, any camera movement in any clip I get flickering, I try to solve this problem with flicker remove in field option or frame blending with time interpolation but can't get smooth motion with new optical flow option I select flicker remove in field option + optical flow in time interpolation and get very smooth motion is there another way to convert 1080p to 1080i to get smooth motion before I edit in AME

all my clips are 30fps, from BMCC, how can i get best result using optical flow? what are sequence settings you recommend? Sorry my English is not strong

that was very helpful. thank you!

Hi, I have a question to make sure I have a clear understanding of using different frame rates. I’m very new and wasn’t keeping my frame rates consistent. I’m right in the middle of a project. Some at 60fps and some clips at 30fps. I’m now keeping everything at 30fps when I talking in the clip. I’m using higher frame rates if I want to use slow motion with no talking. Can I still use all my clips with the different flavors frame rates when I edit my clips in Pr to complete this project. I’m going to use a 30fps timeline at 1080p. I guess I would setup my sequence at 1080p at 30fps. Thanks for your help!

That was my concern always and finally I got a better idea how is this issue of the frame rate. Now, what could be recommendable? To shoot and edit (and set the sequence) in one unique frame rate to avoid these conversions? And maybe AT THE END we can export with different frame rate just to switch from NTSC to PAL or viceversa, for example? Thanks, Colin. Amazing video. All a reveal!

That was what I was looking! Perfect explaination! Thank you so much! BTW, how is this method compared to twixtor (Re:Vision's plugin for AE and Premiere) ? I don't like the workflow of Twixtor (for frame rate conversion) but it has many settings you can play with!

can i add time interpolation in older version of premiere pro cs 6 with out upgrading it or can you tell me the way by which different frame rates clips can playback in time line smoothly without jerking

Thank you!

Hello and thank you for your tuturial i just mixed 24fps and 30fps in a Magix Video deluxe timeline and exported it in 24fps and it played well without laging or jitteringthank you again regards from GermanyGünter

hi, i think this was a little over my head, but im just trying to make a video the starts 24fps, then cuts to 60fps. there has to be an easy way that im missing, but i have been trying to figure it out all day. all source video is 60fps.

hello sir ... i cant find optical flow option in my premier pro cc 2015... just right click on clip but there is no option of time interpolation or optical flow.. thanks

thank you for your video

Hello and thanks for the valuable information .. Currently I'm working on a project with different frame rate video (60fps , 120fps) my question is : in which frame rate should i work in my general sequence that contain all the videos?

If you were editing together a movie trailer, and all your main, longer (story) shots were filmed in 24fps, and your quick glimpse, rapid fire shots were ikn 30fps...would you worry about doing this to the 30fps footage since I'm doing it on a 24fps timeline? Or since the duration of those clips will only last a few seconds, would you let it slide?

Hey I got a question about frame rates. I'm shooting with a Gopro at 60fps and a dslr at 24. When I finish editing and export it at 24fps, will the Gopro video shot at 60fps look weird? Wanted to ask before editing with premiere

Thank You

Thanks

Thanks.. You are a life saver

Thank you for the tutorial! My most footages are 1440x1080, 25 fps so these are my sequence settings but one clip in the timeline is 1920x1080, 29.97 fps. What if I interpret this footage - reduce its fps to 25, scale to frame size and shorten the clip to its original duration with Rate Stretch Tool?

In the frame rate settings, when should we choose 24 or 23.97? or between 30 and 29.97? Thank U.

Hi there! I have a question. I shot video at 60fps but I don't like it at that so I want it to be at 24fps to give it a better look. Am I able to convert it to 24fps? This is another question if it's possible. Now that my video is in 24fps I would like part of the video to be slow motion. As you know slow motion looks best in 60fps. So is there a way to get slow motion from the 60fps and not the 24fps but keeping the rest of the video in 24fps? Thank you,

Hello, first of all thank you for the video, solid and informative. I got a question, would it be possible to multiply the framerate with optical flow? 23,976 to 47,952? I play a lot with the velocity for my client work and it would be great to be able to slow down a 23,976 clip while maintaining smooth slowmotion. I’m using BCC Optical Flow, u can set up the velocity in % and put it to 50% for example. Im trying to convert 23,976 into a higher framerate in order to achieve smooth slow motion with a velocity ramp. What would be the way to calculate the best possible framerate for that? 50/100 slow down optical flow and 47,952 framerate or 66/100 slow down and 32.12784 framerate? I also had the idea to split it In 3 and take 33/100 velocity of optical flow. What would be the best calculation in your opinion? I wanna find the perfect solution, to push the absolute limit of an 23,976 clip in terms of slowmotion and additional frames to increase the room and to have more freedom while speed ramping the velocity curves. Thank you for your answer already!

Hi Colin, is there any option/effect on premiere to display numbers on each frame like your exercise media?

I have one query, sir. Suppose my all footages are shooted in 25 fps and one footage is in 50 fps (want to make slow motion of this footage), then what should be the fps setting of my sequence in premier / how to mix 25 and 50 fps footage in a single timeline with optical flow of that slow-motion footage (that video with 50 fps) / in which format (fps setting) I should export my complete video ? Please help! Thank You.

great tutorials! what about adding a 29.97fps or 30fps to a 24p timeline, can i still use optical flow?

I recorded an event at 60p thinking everything will be slowed down in a 24p timeline, but I realized not everything needed slow motion. So I left some footage at regular speed, but the final video looks stutting. I know once you drop 60 p video on a 24p timeline it drops frames. Will optical flow compensate for those missing frames to look smoother? I’m also using Premiere Pro 2019. Thanks.

This would work if the clip is slowed down or speeded up wouldn't it? Thanks for the video.

This took me months to come across this problem!! i knew it was a time interpolation but damn!!! Thank you for providing this! So if I come across this problem the screen or glitch is known as an artifact?

help, i dont have time interpolation option in the right-click menu and neither in speed/duration tab. please help me since there's no answer in google !

Hi! What do you think about optical flow? Is It most smoth than others?

Optical Flow is great but what if we have 1 part of the sequence that is optical flow and the rest of the clips are Frame Blending when you export everything in this area 7:15 it asks you which interpolation. in which case you only get to choose 1 option. Will it detect the Optical Flow parts of the sequence or it will just export the entire sequence as Frame Blending?

I would love to know your recommendations for a video card that Premiere likes on a MAC..not the garbage can Macpro but the older ones. There seems to be some acknowledgement that some cards are better than others for certain OS version and mother boards but I am looking for the best value for performance. Some cards, while high in cuda cores , will cause some abberations on the screen sometimes...certainly on some MacPros on older systems.

how not show my time interpolation in prm pro cc 2015

It sounds like for broadcast and film You should rerender any footage that is different from your timelines frame rate with 3:2 pull down... But for other cases optical flow or frame blending

Hi, I'm a wedding Videographer from Malaysia. I'm using cs6 and most of my clips shooted at 60fps and some 30fps and also some 50fps. . What will b your best advice on which sequence setup to use for the editing. Do I need to choose DSLR 24fps 1080 and dump in all the clips and modify it to 24fps?

There is another way to deal with different speeds, if you have 24 footage on a 25 timeline, it works always perfect. Just put 104% speed on the 24 clip, result is no duplicates frames, no stutter. Frame rates with larger differences with the timeline, can also be calculated in speed compensation, but can be noticeable if the speed of the clip is made too high. 24 to 25 works perfect though.

sir in which adobe version i can use this feature optical flow. i have adobe premier pro cc v9.0 but in this version this feature is not available. i have to upgrade in which version

How did you add a time marker to each frame?

Question, i have footage that I've shot at 60fps but when I import into Premier it brings it in as 29.97,why and is there a fix? I used a Panasonic AG-HPX 170 with P2 Cards it records MXF files/AVC-Intra100

Colin, I am trying to work with Skype interview footage, and change the frame rate to one over all 24 fps. ...Some clips range from 10, 15 fps and 24 fps. I need to change the frame rate of the 10 & 15 fps, to 24. How do I do this? Do I need to create a project w/ 24fps first and drop it in (will it change?). I am obviously new to all this. Please if you can walk me through this... Thank you. Amy

Hi Colin, Can you please help. I record in 50 fps , shutter 125 , then slow down 50%, export to 24 fps and looks like the footage is loosing 2-3 frames in each video clip... Optical flow does not work.

i have pr pro cc2015 and do not have/ can not find optical flow anywhere

So you can't have a timeline which contains multiple frame rates that all play at real time without changing them to the uniform frame rate of the timeline? Why is that? Why can't I have a 24p movie and then all of a sudden an action sequence that's 60p in that movie?

When you conform the frame rate in the media exporter it works as well as in the program but when it cuts between shots you get a couple frames of craziness. Is there any setting to tell Adobe Premiere not to mix between shots?

how to remove acne , face clean on adobe premiere pro ?? Please help! thnx

one question ,when i use optical flow and before i render in the timeline, results my videos get many flashes black and white why? my video get bad by the way i use a computer corei3 , 6 ram ,card video gt force nvidia 210- 1GB

Hello sir...I am your subscriber...From India...I am poor in english...I little bit confused...In time line no need to set optical flow.. Only set exporting time optical flow set it..Sir Second doubt sir...If I use 25p 50p clips for timeline setting sequence set it 50p...It won't work optical flow sir

How exactly is a frame defined?

whats GPU accelerator ?

Hey, what's up? I'm working on a youtube music video right now which has a lot of clips with different frame rates (24, 25 & 30). I've already edited a huge part of the project but completely forgot about the fps. I assume rendering it at 24fps will cause the video audio timing to be off (?). Do you know a solution to my problem? Thanks.

HOW do i best dm you?

Thank you!
