24p footage (GH4) flickering lights

Hi guys and non-guys,
So i recently bought the Panasonic GH4. Loving it! So i was up for some testing.
I filmed everything in 4k: 24p (with the system freq. on 24.00Hz). So i imported everything in Premiere, created a 24p sequence with an 1080p resolution and did some quick editing.
Exported the sequence with h264 codec and tried it with 25fps and 29fps. Both video's are getting light flickers after the export.
I'm not seeing those lights flicker on either the camera or when previewing in Premiere. Here is the test video i made, you can see the flickering in some shots: GH4 4k to 1080p
Is there anything i'm forgetting? While filming? I shot on a shutter with 1/25 if i'm correct (with f 2.8).
Hope you lads could help me out, as i Google'd the whole internet for an answer.
Thanks in advance!

Ok ... first there's a list of info to provide when asking questions ....OS, RAM, video card w/vRAM & driver, maybe disc layout; footage codec (which you did list, thanksl) and specific to the dot versions of software and any 3rd party plugins or converters used.
Next ... all of this footage was indoors and seemed to involve electric lighting. There can be major problems with flicker with the frequency depending on the type of light and the regions AC frequency. Have you tried some outdoor footage and is the flicker gone?
If you go outside & are flicker-free, then it's a shutter speed issue. If not, you've got something happening in ProPro. Question: did you set the footage specs for the sequence befor putting a clip on it, or do the more common & easier method of just creating a new sequence without touching settings, then drag a clip onto it? In your case you would then tell PrPro to interpret as 1080p I think.

Editing 24p footage - FCP or Vegas?

I'm planning on using a dvx100b to shoot a project in 24p (or 24pa). For editing, I quite naturally was going to use FCP (29.97 & 23.976 timelines respectively), since I already own the software. When I mentioned this to an acquaintance who is an experienced Vegas editor who also did a little work on FCP, he was adamant that Vegas is vastly superior to FCP for 24p editing. Not having ever edited 24p(a) footage, I was taken aback, and lacking in information to confidently express any opinion. Im not clear on why it would make a difference... what's going to be different editing such footage on FCP from just regular non-24p footage?
Also, I don't want to spend the money on Vegas, or the time to learn the software, not to mention having to upgrade my windows gear (I only have a 3 year old Dell Inspiron 1100 w/ XP). Bottom line, I really don't want to do this, unless there are very compelling reasons.
Is anyone here familiar with both Vegas and FCP who can shed light on the issue? TIA.

Thanks, Capt. Mench, that is quite helpful, as I'd rather stick with FCP since I already am a bit familiar with it (not 24p editing though), instead of learning another software like Vegas from scratch. I hear you wrt. Vegas... my purpose was not to diss Vegas, but rather I was worried that FCP had some kind of issues when it comes to dealing with 24a(p) footage and Vegas did not. If it's just that Vegas workflow is "better" in being slightly more intuitive or economical or ergonomic, I don't care. If FCP can do the job without hiccups (even if less "iintuitively" than Vegas), then I'd rather stick with FCP.

Why is my iPod Touch 4G screen flickering light and dark?

my iPod Touch 4G screen flickering light and dark all the time?!?! I also have this problem where at the VERY bottom of the screen, Theres this white bar that keeps flickering on and off!! PLEASE HELP ASAP!!!

The screens are practically the same.
Did you purchase your iPod Touch second hand or direclty from the Apple Store? I would recommend that you go back to the Apple Store and show them both devices in action so that they can advise you closely.

What is the best way to work with AVCHD 720 24p footage in FCE4.1?

Hi I have a Panasonic HMC-150 and I've been shooting 720 24p footage at 21 mbps transfer rate.
I was wondering what is the best way to work with this material in FCE 4.1? I see that in the easy set up menu they only have the option of 1440X1080i at 50 or 60 fps or 1920X1080i at 50 or 60 fps.
Also in the rates drop down menu there is only 50 or 29.97.
So I was wondering which is the best choice for 720 24p footage and will it look alright in any of them? Also is it possible to customize these settings?
And finally can you work with faster transfer rates (21mbps) in FCE?

Yikes, this is going to be tricky since FCE does not support native 24p editing.
The work around for some of us is that AVCHD material that is 24p is often recorded to disc at 60i using telecine, in which case it can be editing at 29.97 frames per second, and then detelecined afterward for final export at 23.98 fps. The problem is that I think your camera actually records real 24p - not 24p packed into 60i. When you import the material from the camera what does QuickTime report the framerate as?

24p footage out of sync

I just imported 24p footage, encoded in SS.
Encore took it, but the video plays much faster than the audio, and so much that the people are sped up. It looks funny!
I'm running, CS3 and SS5. The 24p footage with encoded at 12 iFrames and Closed GOPS. The imported audio is a wave file from the 24p project. Even after Encore transcodes the audio the problem remains.
Any help would be greatly appreciated.

Not sure of the 'button'.
One thing you should check though...
How are you monitoring this? Is your audio following your video to/from the same source?
Turn on your wave form monitors for the timeline... does the click line up visually on the timeline to the clap of the slate?
If you monitor your audio off the CPU and your video externally... or your audio out FW and your video only on the cpu... you can get sync issues. Actually LATENCY issues and not really out of sync.
Are you sure it's out of sync and just not a latency issue?
Thanks for answering...

BLURRY images when I Modify speed in 29.97 timeline with 24p footage

I am modifying the speed of a clip - only to 90% - and parts of
the clip appear blurry after I render.
Any ideas why? What can I do?
Thank you in advance!

Is it 24p footage with 3:2 pulldown or, just 24p media?
Either way, you're in for a fun time.....
for 24p with 3:2 pulldown, first use Cinema Tools to remove the pulldown. Now, use Cinema Tools to conform it to 2.9.97fps. Now take it into your timeline and adjust the speed.
For 24p media, just conform it in Cinema Tools to 29.97fps, and then pu in your timeline and adjust the speed.
What you're doing is avoiding having FCP convert the 24p to 29.97fps by adding frames, before it gets to the speed change. Similarly, 24p with 3:2 pulldown must have it's pulldown removed before you can do a speed change.
This should make things nicer for you!

Canon .mts import 24p footage doesn't work ~

I was excited to see Premier CS5 could import Canon's 24p footage and had project settings ready for it.
I was dissapointed to find out that this function doesn't work. Premier shows my .mts files being 29.97 fps so I'm assuming the camera must inclose the 24p footage inside 29.97 fps container?
Does anyone know a simpe way to open a .mts file in After Effects, interpret the footage to "Guess 2:3 pulldown" open, and save export the file back into Premier?
I can't seem to figure out how to export the interpretted footage from After Effects back into Premier.

Why are you guys going through all of this trouble?
Premiere works fine with 24p footage if you shoot it that way. I use it all the time. XH-A1 has both 24p and 24pn.
One is 24p in a 29.97 wrapper and the other is 23.976 native with flags. Shoot with the one you want and just use the right preset.
Sorry...I didnt realize you left out the camera you were using. If it's ont that doesnt have both modes you will need another software to remove the pulldown.

Best DV deck for capturing Panasonic 24p footage

Hi everyone,
I'm working with 24p footage from Panasonic DVX-100A and HVX-200 cameras. I've always found the tapes tricky to capture with Advanced Pulldown Removal, and now I'm unhappy with my Sony DSR-11 VTR.
I'm finding that some equipment plays nicer with 24p footage than others.
Some of my editing colleagues have suggested that I should use Panasonic equipment - and they do have an equivalent low-end DV deck, the AG-DV2500.
Any suggestions from the field? My budget does not permit buying a full-blown studio DVCam machine, unfortunately.
Joe

I put this question to Larry Jordan, of newsletter fame, and he feels that I'll be better off with a Panasonic VTR - so I'm gonna give that a try.

24p footage shown as 29.97 in DVD Studio Pro

Hello,
I shot footage in DVCPRO HD codec with the HVX200 camera using the 24pN (native) recording format.
I edit everything in FCP 5 and when exporting to Compressor using the output DVD 90min best quality 16:9 everything is still OK. The video file (when opened in QT) shows that it's a 23.97 fps file as it should be.
BUT after importing it as asset in DVD Studio Pro 4, it shows as 29.97!! WHY? The video is smooth though, but why does it not show as 24p footage?
PS: everything is in NTSC (camera, FCP, DVD Studio Pro)
Thanks for any quick help,
JERRY.

Do not know if you have DVD Demystified, but page 9-34 says what you are saying. (Wanted to double check to make sure I said it right and I was starting to get a bit lost here also. Too late at night LOL )
DVD-Video supports 525/60 (NTSC 29.97 interlaced fps) and 625/50 (PAL/SECAM 25 interlaced fps) In the case of 24 fps the MPEG Encoder adds repeat first field flags to perform 2-3 pulldown fo 60 displays, for PAL a 4% increase in speed.

Not allowed to import 24p footage

Hi in iMovie 08 I could import 24p footage but with iMovie 09 it wont let me. What gives

From what I recall iMovie has never supported 24p playback. Go to iMovie's preferences, (any version of iMovie) and look at the video standards drop down list. You will only see 30fps and 25fps. So even if you could get 24p content into iMovie '09, you'll probably have problems with it when you make projects.
24p has always been a pro-sumer and professional format. To properly edit this footage you'll need software that has this playback and editing mode. Final Cut Express and Final Cut Pro are you best options for this.

Film workflow with 24p footage: nightmare

Hoping someone can give advice on a disaster i'm experience as I cut a film I'm working on, the sequel to this-
http://www.youtube.com/watch?v=GpuEMSH6zB4
I shot the film in straight-up 24p. When capturing the footage at 24p, we experience a quality loss. At 29.97, there is no quality loss. This makes no sense.
Also, when I get my 24p footage, captured at 29.97, into a 29.97 timeline, and then resder it out at 29.97, there is a quality loss.
Also, my ability to have moving video not only in the FCP viewer window, but also through the camera out to a TV, comes and goes. It will freeze or unfreeze depending on some thing having to do i think with the framerate of either the clip or the sequence.
It's blowing my mind. I did not experience this problem on the last flick, and I shot it the same way. Is my FCP damaged? Is there a tutorial out there to guide through this problem, or have any of you experienced it?
Any info would be greatly appreciated.

24P runs at 29.97. 24PA is what you shoot if you want to work at 23.98. If you shot 24P, then you work at 29.97.
You capture as normal 29.97 DV footage, edit at 29.97, output at 29.97. You use no pulldown.

Does converted MTS 24p footage also require "pulldown" process?

Hi.
I am using a Canon HF20 camcorder. The files are MTS. I was shooting in 24p mode. I have FCP 6, which apparently cannot handle MTS media. So I found a way to convert the files to HDV (or AIC) via an application called Clipwrap. My question is: Must I also deal with the extra-frame/pulldown problem (endemic to usual 24p footage) of the new clip, or has that been taken care of in the conversion process? If not, is there a way to tackle both these issues (MTS conversion, pulldown) in one fell swoop?
Thanks,
Marc

you can usually drop 24p material into a 29.97 fps timeline without any issues EXCEPT that fcp does not add pulldown in the best way. If I remember correctly, fcp just repeats the 4th frame. This may or may not be objectionable when you view it. You can add pulldown with full flexibility in After Effects. I don't imagine it would be a big deal to do this after you've locked picture.
My mantra is 'TEST YOUR WORKFLOW" from soup to nuts (ingest to output in delivery format). I sometimes make DP's, producers, etc crazy, but better them than me.
And yeah, sometimes it is just simpler to shoot 29.97. But most importantly is what is your end use. i recently finished a doc that had to be output to a digital cinema package for academy award consideration. The specs demanded 24 fps (not 24p aka 23.976). My sources were all over the place. Landed up using compressor to change the frame rate of all material to 23.986 and then the post house doing the dcp output conformed to 24.

Premiere messing up 24p footage

My 24p footage looks like crap once I put it in the timeline or export! Every 4th frame looks "interlaced". I believe that is what is happening, but I'm not sure. And I definitely don't know why it's happening.
-I'm using a DVX100B with 24p setting (not 24pA) squeezed for widescreen.
-Premiere Pro CS3 Mac OS
-24p widescreen project in premiere.
-Import the video using Quicktime "DV/DVCPRO" Compression with the 29.97 frames, Progressive, and 16:9 settings.
(I was able to figure out that 29.97 is the correct setting, because even though the footage is 24p, it's laid down on 29.97)
Video looks good after importing. I can play the clip and it's fine or play it outside of premiere fine. But as soon as I drop it into the timeline and play it in the preview window, I can see that every 4th frame looks interlaced. The result of this is it plays like crap on a TV because every 4th frame has a flicker effect. I've also tried exporting from the timeline and it still does this interlace/flicker effect.
Any help MUCH appreciated. Footage looks great, but I can't do anything with it until I fix this problem.
Thanks!
John

Hvx200 1080i 24p Footage not Properly Reverse Telecining

So I've got a bunch of footage that we shot using the 1080i 24p setting on the hvx200 which yielded 24-in-60 footage, which normally isn't a problem and the other 2 cameras we were shooting (an hv20 and hg10, both in 24p mode) produce the same kind of files. after batching everything out to compressor to remove the telecine, and convert to 1920x1080 prores, i just discovered that all the HVX footage is true 24p, but didn't remove the pulldown correctly, and most every frame is now interlaced.
I'm trying to figure out if it's a compressor issue, a dvchdpro issue, or a computer/install issue. I've had some QT plug-ins that break the reverse telecine function, but considering the hv20 and hg10 footage converted just fine i don't think it's that.
also, after trying to convert to directly to prores and run through cinema tools to do a manual RT, i don't get the option to RT. and lastly using JES Deinterlacer when i set it up and submit i get a "cadence not found" error. it's also is reading the file as progressive when i first put it in JES.
I've also tried running the RT through final cut directly as some of those old pany cams have RT flags and FCP can handle the RT process internally.
Any thoughts anyone? has anyone ever run 1080i 24p footage through compressor and achieved a true 24p framerate, or do i have an isolated instance here?

so after sleeping on the problem, i took the footage and ran compressed it out to prores422, this time making sure to select a frame rate of 29.97 AND checking the "interlaced" button on the codec page. after batching the footage to make it true 60i, i then ran it through compressor again to remove the pulldown, and everything worked as it should. I think the problem arose from the footage reporting itself as DVCHD PRO 30P instead of 60i, and compressor wasn't seeing any fields and therefor not seeing any cadence

Importing HV20 24P footage

I imported 12 hours of 24P footage from the HV20 into Final Cut using the HDV 108024P preset before reading the instructions of how to make it "true 24P" that say that the footage needs to be imported as "HDV108060i".
Do I need to reimport all that footage to do the steps needed to make it real 24P?
Also, if I did not change it to real 24P and added it to a timeline that was 24P with A1 footage would the two look the same or would the HV20 footage have some issues?

Hello,
When you say imported, do you mean imported from a file, or captured from the tape?
When you say 24p footage, have you already done the reverse telecine process on it?
The camera shoots 24p, but stores it as 60i on the tape. When you capture, you end up with 60i data, with duplicate frames on a cadence (you can check this just by stepping through your video frame by frame and watch for duplicates)
You can take captured 24p video (which is contained in a 60i format) then use compressor to remove the extra frames. Then you can then place that clip in a 24p sequence and edit as you wish.
I would guess that when you say you "imported" 24p, you mean that you captured the HDV from the hv20 something you shot in 24p mode. FCP would have captured it as 60i video, so you probably don't need to re-capture it. Just place the entire capture onto a sequence, accept the format of the input, then send it to compressor to change (reverse telecine, aka removing the extra frames) the 60i sequence into a true 24p sequence. then you use this true 24p material in a new sequence that you can then trim and edit.
