Variable Frame Rate

If I have clips that were recorded at different frame rates, say 24fps and 60fps, and I put them in the same video project, how does PE11 handle this? Will it cause issues or lower the quality?

Slow motion for your 1080p60 will be achieved in either of three ways in Expert workspace (project preset no part of this):
a. Interpret Footage. Frame Rate section of the Interpret Footage dialog. Right click file in Project Assets, select Interpret Footage, and, in Frame Rate section, dot Assume this frame rate, and type in your wanted frame rate)
b. Time Stretch. Set Duration for less than 100%. This will increase the length of the video and apply a slow motion effect.
c. Time Remapping.

Until proven otherwise, I would use the
NTSC AVCHD AVCHD 1080p60 project preset
and apply Interpret Footage to that video for which you want a slow motion effect. You could also consider Time Remapping feature with or without Frame Blend option that is built into Time Remapping.
I never use the frame rate same as source for exporting. It typically does it own thing under those circumstance and that is not always the frame rate that should have been. I would take the time to specify the frame rate in export along with all the rest of the export settings.
If you are going to upload your Expert workspace Timeline to Vimeo, I would try the settings suggested by SG...that is, Publish+Share/Computer/AVCHD with Presets = VimeoHD. The default there is 1280 x 720, so I would customize the setting under the Advanced Button/Video Tab of that preset to give 1920 x 1080. Set the Level and Profile first, so that you can type in the 1920 x 1080 values. Then you would upload the AVCHD.mp4 file that you obtain and upload it to Vimeo at the Vimeo web site.
In the following Export Settings dialog for that export. I have the frame rate set for 59.94 progressive frames per second. Depending on your project plan, you can reset that to your preference
If you decide to upload your Expert workspace Timeline to Vimeo via the program's Publish+Share/Online/Vimeo with Presets = VimeoHD, you cannot change the 1280 x 720 resolution there.
Please review all comments and let SG know of your progress.
Thanks.

Why doesn't Premiere handle variable frame rate video?

Variable frame rate video comes from many places these days: phones, live streamed video recordings.
Adobe Premiere is a supposedly production level piece of software that cost a good chunk of change.
How is it 2012 and Adobe does not still have an answer to this problem? After trying to editing/convert/mux/edit variable frame rate videos for the past 5 hours I am just exhausted. No amount of conversion apps, etc have saved us and THEY SHOULD NOT HAVE TOO.
We have spent thousands on Adobe software packages over the last decade, probably 10s of thousands, and the only answer I find consistently is to switch to Vegas.
Surely, SURELY someone at Adobe with real insight into the issue can help answer the question of whether users moving into different medium should find a place elsewhere in the software ecosystem...

The file I am trying to edit was recorded in a streaming application called XSplit, very popular in the game / live streaming community.
The frame rate is variable, slightly I am guessing, because the real time nature of the recording/stream. The issue is that while WMP and VLC play the file back 100% correctly, when played back inside Premiere CS6 the file drifts out of sync so at the end of a 2 hour clip, we are talking more than a full second or so.
According to MediaInfo, here is the file detail:

Variable Frame Rate on H.264 output

I am using AE CS6 (cloud version). I am trying to render compositions to 1080p mp4. Each time the comp appears to render fine. But bringing it into my NLE crashes my NLE. I brought the media into MediaInfo (app from SourceForge that shows everything about a media clip). It says that the Frame Rate is VARIABLE Min: 60fps; Max 60.6 fps. The composition was 80 fps, and I told the renderer to keep it at 80. MediaInfo also said the duration was over 6 seconds. The composition was a little over 4 seconds. So the overall speed of the comp was incorrect. I've been in the video business for about 10 years. I understand frame rates, etc. Never heard of VARIABLE frame rates until this.
I was able to launder the media file through a freeware media format converter, and got it back into constant frame rate so I could proceed in the NLE with the project. But the time was still 6 seconds. So I had to speed up the clip in the NLE to get it back correct.
Since moving to CS6 from CS4, I decided to start using the H.264 output module. So I've just started encountering this variable frame rate problem.
So my questions... What is variable frame rate, how did I 'request' it, why is even the variable frame rate no where near the comp frame rate, and what do I do to simply get an mp4 with the 80fps that I want?
This is very reproducible for me. My comps are usually either HDTV 1920x1080 or HDV 1440x1080.
Add to Render Queue
Select DV Settings, change field order to none
Select H.264 output module
Render
Can someone explain what's going on?
Thanks.
Jerry

Where did you get that footage and what format was it originally shot in? Was it shot in slow motion or did you change the frame rate in AE? Why would you need 80fps footage unless you're going to slow it down to a normal frame rate?
Also, h.264 is not only a very lossy format, it's also a bad intermediate format. So if you're planning on editting that footage later on in an NLE, I'd suggest rendering it to something else. Premiere should work fine with h.264, but not FCP, although I think they fixed it in FCPX, but you didn't say what NLE you're using.
Second of all, the H.264 encoder is much better in Adobe Media Encoder. Check this post by Andrew Yoole:

As the other guys have said, don't use AE to render using temporal codecs. Temporal codecs like H264 rely on storing partial frames based on earlier information. AE renders and encodes one frame at a time, so most of the efficiency of a codec like H264 is lost. The result is that you get much lower overall quality from an AE h.264 render than if you were to encode it externally.
Adobe Media Encoder or Quicktime 7 will encode great quality H.264 files.
Was this helpful? Yes No
As I said I'm not sure why you would need to take an 80fps piece of footage back into an NLE, but if you're trying to make that footage play back in slow motion, you're going to have to re-interpret the frame rate of the footage in After Effects to play back at standard rate. And, if you're going to use the AE Render Queue to output something for more editing, I would suggest using best settings and outputting to a production codec such as a ProRes, Animation, Uncompressed 10bit, Uncompressed 8bit or Black Magic.
Also I've never used that media info app before, but I know that when you open up quicktime and hit command I on the mac to view the inspector, the playing fps jumps around. I think this happens because the player doesn't necessarily play back the correct frame rate at all times.
This Adobe Captivate blog talks about variable frame rates in F4V files. Maybe it might help explain things.

Audio sync issues with variable frame rates as well as .ts files

I'm using Premiere Pro CS6 and CC, in Windows 8.
I bought an AverMedia Live Gamer HD card to capture 1080p footage with, and the the videos it produces work perfectly during playback. No sync issues whatsoever. I'm saving them as MP4 at 30fps.
The problem is when I import them into Premiere Pro, the audio loses sync at certain points. After a bit of digging, I've discovered that the videos have a variable frame rate, which Premiere Pro does not support. I don't know why, considering competing products that are significantly cheaper can handle them with a problem, but oh well. The capture card can also save videos in .TS format, which produces a constant frame rate, however when I import them into Premire Pro the sync is immediately off by a second or more. I assume this is for an entirely different reason. Again, they play back normally without a problem. Upon emailing AverMedia, I was told this was Adobe's problem and there was nothing they could do about it.
What I'm wondering is if there is any sort of realistic solution to this as of now. Is there any way that Premiere can work properly with files that have a variable frame rate? If not, is this being worked on?
Or maybe there's a way to get the .TS files back in sync, that way the variable frame rate issue doesn't matter anyway.
Converting the files is not a long term solution. I'm working with hours and hours of HD video, and it would take way too much time to do this.
Manually resyncing the audio is also not a solution. Again, this would just be way too much wasted time with each project.
The only solution I see as of now is to switch to Sony Vegas until this problem is resolved in Premiere, if it ever is. I'm really hoping there is some other way, so if anyone has an idea as to how to fix this, I'd really appreciate it.
Thank you.
tl/dr:
Is there any way to get around Premiere Pro not working with variable framerates? My .TS files are also out of sync, is there any way to fix that? Without converting or manually resyncing.

>If not, is this being worked on?
Discussed many times before... never a "yes" answer to your question... tell Adobe what YOU want at https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
If enough people make a request, Adobe MAY add the feature (I don't work for Adobe, so no guarantee of anything)

FCP ERROR when trying to convert variable frame rate Panasonic P2

Ok, yesterday I was able to convert variable frame rate footage so it rendered out nice slo mo's via DVCPRO HD Frame rate converter in FCP 6.0.4, it worked perfect. I tried it multiple times - So I know it can be done... Today however I created the same "easy setup" in FCP I used yesterday, and it wont work?
it comes up with the error:
"An error occurred during processing, unable to conform source media FCP" is there some setting that by default switches"
has anyone heard of this happening? it seems like a program error... but I could be wrong... I haven't been able to figure it out on my own.
does anyone have any suggestions?
Thanks!

Lance,
Sounds like you have done a very thorough job of tracking down your problem and a temporary solution. Just one question. Is the footage from the HDX-900 that you say...
Lance Moody wrote:
Since some footage from the HDX-900 was shot at 60FPS for conversion to 24FPS as slo-mo, I then attempted to use the DVCPRO HD Frame Rate converter to accomplish this.
flagged in camera as being 24fps or are you just trying to convert it after the fact?

I want to step through a .mov file frame-by-frame looking at geometry of an aircraft in the video to establish the rotational speed of the propeller. This should be fairly straightforward by looking at how much the propeller moves between each frame and using the exposure time of each frame.
However the .mov file is from an iPhone 4S and looking at the details, has a variable frame rate. What I need to know is the duration that each frame is displayed for in order to do my analysis. Does anyone know how to find out this information?

Does PPRO CS3 support Variable Frame Rates on P2?

If not, how is it converted to edit?

Weird, I have some VFR clips that will not import into PPRO. All other clips that are ot VFR import just fine. I get an error message from PPRO on the VFR clips saying that the file format is not supported or the file is damaged.

How can I change the frame rate mode?

Adobe Premiere Pro exports my videos with a variable frame rate. Because of this long videos are asynchronous. How can i change the frame rate mode? So Adobe Premie Pro exports my videos with a CONSTANT frame rate? The original video has a constant frame rate...

Sorry my mistakes. I am from Germany.. so...I mean with asynchronous that the video file and the sound file are displaced. In the beginning of the Video it's normal, but if the videos is very long it goes VERY "asynchronous"
I analyzed the video with "mediainfo":

And there i can read that the "frame rate mode" is variable... and that's the bad thing... I want to change that point to a constant frame rate mode. I use the H.264 codec

How to export a flash project with a changing frame rate to a video

I have a Flash project that is a series of roughly 1000 images. The result of the images is a simple animation, and there is music imported on a separate layer.
There are moments in the music that I wanted to line up with certain frame changes, and there are sections of the music that I wanted to match up with a faster (double-time) frame rate.
I used this code in several places in the a code layer:
stage.frameRate = x;
The result is exactly what I want in SWF -- the animation speeds up and slows down at the exact right moments to match up with the music track, but it seems like it's just not possible to export this variable frame rate project to a video file?
According to the accepted answer on this post: http://forums.adobe.com/message/4019538, it seems that:
The export function in Flash Pro doesn't transcribe *frames*, rather it plays the Flash animation and records it like a camcorder
If that's true, then I would think there is a way to record a variable frame rate project into a video -- does anybody know if this is possible?

That or Premiere would both get the job done. After Effects might be more desirable as it has a feature called Time Remapping (right-click on the video layer, Time->Enable Time Remapping). You can add keyframes to any point in a video and then drag them around to speed up or slow down the video. That'll allow for very precise tweaks.
Finally all I'd suggest is when you jump into your next project, make a quick dummy test project to see if the software you're using is easily capable of producing what you want. It'll solve the headache of completing the project only to land where you are now. Now you know Flash won't play nicely with scripts and Export Movie. If your desired end result was always a video I'd probably use video editing software to make the video. There's some free stuff out there if you really look, but no, it won't be as nice as After Effects or Premiere by any stretch. Although when you see how amazing After Effects is, you'll probably want to buy it .

Why did frame rate of video shot on iphone 5 change from 30 fps to 24 fps?

Why did frame rate of video shot on iphone 5 change from 30 fps to 24 fps?

My understanding (which could be wrong) is that the iPhone shoots video with a variable frame rate. This is likely so it can optimize video for FaceTime. So uncomplicated scenes can be shot with a lower framerate, and active scenes will be shot with a higher framerate.

Most efficient way of changing still image frame rates?

I'm using Premiere CS5.5 and have been having issues with the audio/video going out of sync when I upload my video to Vimeo (it's not out of sync prior to uploading it...it only happens after they transcode it). The Vimeo support staff says the problem is that I'm using a variable frame rate, but since there isn't any option (to my knowledge) to choose a constant or variable framerate in Premiere/Adobe Media Encoder, I think I have identified the problem. The primary footage that I shot with is 23.976 fps and that is what my sequence settings and output settings have been, but I also have a lot of still images that I'm using for b-roll, which I finally noticed are 29.97 fps. I changed the Intermediate Media Timebase setting to 23.976 fps in the preferences, but my question now is if there is an efficient way to change the frame rate of all those still images without having to re-import them and re-apply all the various motion effects/key framing that I've already spent a lot of time on?
Any help would be much appreciated. Thanks.

Yeah, I downloaded MediaInfo to explore some of the various versions that I've rendered in my effort to get something that works correctly on Vimeo, and depending on the encoder I saw some of what Ann posted, but I also looked at one on MediaInfo that I had rendered through Adobe Media Encoder and it had a Constant frame rate mode of 23.976, yet I remember watching that one on Vimeo at the time and it was still out of sync--Mediainfo says that version has a variable audio bit rate though, but to my knowledge there isn't an option in AME to choose a constant audio bit rate.
I agree that it's an issue on Vimeo's side, but the chances of them getting their **** together in a timely fashion seem low. The frustrating thing is that I can watch documentary style videos on Vimeo that I know were edited and compressed through Premiere/AME, yet they don't have any audio sync issues. The difference that I noticed between one of those videos and mine is the use of still images in my video. As you can see from an image I uploaded earlier, the default frame rate for still images when I imported them was 29.97 until I changed it yesterday, but it didn't update the images I had already imported. So I'm wondering if there is a way to change the frame rate of those still images without having to re-import the images and make all my edits/key framing all over again.

Confusion about mixing frame rates......

what are these guys talking ....does this happen automatically that fcpx adjusts variable frame rates according to the project settings..?
https://discussions.apple.com/thread/4505699
because it did not happen with me in a 23.98 timeline the clips with 25 fps did not sync......

Not sure what you mean by sync. You mean the audio is out of sync?
I looked at the thread you linked to. The software should be able to handle mixed frame rates quite well.

Wrong capture frame rate

Hi,
I'm trying to conform a movie from recapture, and I'm with troubles.
I'm capturing from HDCAM 1080i 59.94 and after capture my material should be 29.97fps. But always is different.
Sometimes is 29.95 or 28.54 well... severals differents values.
I see the speed of image is OK, I haven't drops.
But when go to conform the timecodes doesn't match.
FCP shows correct frame rate on Bin, but QT shows these variables frame rates.
Anothers programs as Autodesk Smoke and Assimilate Scratch recognize the wrong frame rate too.
I have a Mac Pro 12 core, using the latest Snow Leopard, FCP Studio 3 and QT.
For storage have a External SAS disk array with 32 TB wich has a sustainted througput of 700MB/s (fully tested and OK).
For capture I'm using a Aja Kona 3.
Actually I already saw this problem in anothers versions of FCP and anothers machines.. but I never get to fix it.
Please, someone already had this problem and fix it?
Thanks in advance.
Thiago Cabral

QT almost is always wrong. It plays what it can... and with Snow Leopard, QT X is just worse. The fact that Smoke and Scratch report the wrong frame rate is really puzzling. Try this...use the CONFORM option in Cinema Tools to conform the footage to 29.97. Might be just the thing needed to LOCK that frame rate still.

Audio out of sync after changing frame rate

Hello
I just changed frame rate from 23.976fps to 24fps inside sequence setting, and the audio is out of sync in timeline. I can certainly manually right click mouse and choose slip into sync, but it's a tedious job. Anyone knows why and quick solution?
Thanks
Richard
ps I use 2014.2 latest version

>Frame rate mode : Variable
No version of Premiere does "well" with Variable Frame Rate
Below is about iphone, but may help

Recording with constant frame rate in FMIS 3.5?

I'm running into audio/video sync issues when converting .flv files to .avi files with FFMPEG 0.5. Is it possible to force FMS 3.5 to record video with a constant frame rate? I set the FPS vaule to 15, but that doesn't work. Setting bandwidth or quality to 0 doesn't do the trick either.
public function onStatus( e:Event ):void {
                publish_ns = new NetStream(nc);
                cam = Camera.getCamera();
                cam.setMode(200,200,15);
                cam.setQuality(100000, 100);
                cam.setKeyFrameInterval(15);
                publish_ns.attachCamera(cam);
                publish_ns.attachAudio(mic);
                webCam.attachCamera(cam);
                publish_ns.addEventListener(NetStatusEvent.NET_STATUS, statusHandler);
When I check the metadata tags for the flv files with MediaInfo.exe it says "variable frame rate" for the FPS value.
Thanks,
Pete
