Flash Frames on h.264 Export

We are exporting an edit for web using the h.264 codec. The edit plays through fine on the timeline but each time we export there are a couple flash frames in the edit. These flash frames usually occur within a second of an upcoming cut and will flash a frame of the next shot we are going to prematurely.
My initial thought is that it has to do with the Key Frame settings on the export or is perhaps due to bad render files. If anyone has experienced this and could point me in the direction of what the issue is that would be much appreciated.

If you are exporting to h.264 directly from the FCP timeline, try exporting the sequence as "current settings" then do the conversion in Compressor.

Red flash frames on C300 sequence exports

Still no fix for this widely noted issue, Adobe?
I'm currently trying to get a job completed and the process of getting anything out of Premiere is absolutely painful...
I have tried all the suggested solutions - trashing preferences and media cache files. I saw somewhere that removing any clips that are a different codec to your footage (in this case it's MXF files from a C300) fixed the problem. Tried switching hardware GPU acceleration off. None of these things have worked. I've had to export the sequence several different times and then stitch these exports together in a new sequence (skipping out the numerous red flash frames, of course) just to get a clean export out. Pitiful.
I can see reports of this happening over a year ago - why hasn't it been fixed? I think it's pretty scandalous that this hasn't been sorted - Premiere is advertised as being able to handle these camera formats natively...well, it can't right now for me if using the native camera files results in issues like this.
Has anyone found any other work arounds that I haven't noted above?

Hi Mark,
According to the "about Premiere Pro" window, I am on 8.2.0 (65) build.
I have had the same issue exporting out of both Premiere and Adobe Media Encoder - the build of AME is 8.2.0.54.

Black flash frames introduced upon QT export

I'm having an issue where upon exporting a QT of my sequence, it introduces one-frame black flash frames in between every cut, both in the QT and in the sequence. This is a standard DV NTSC 48kHz sequence. Running FCP 6.0.5. Any ideas?

Is this in your timeline too? Zoom in between two cuts to see if there is a gap between clips.

How do I get a lip sync flash frame sequence to encode properly

I built a flash frame sequ
ence in Premiere. It is 2 seconds long with the
first two frame white and the remaining time black
frames. This is repeated for 1 minute. If I encode it in non-compressed AVI it is correct. If I use
MPEG2 or H.264 to build a transport stream, I see two white frames
as I would expect,then black frames for the rest of the sequence. Over 15 seconds, I will start to see three frames, gray, white and gray again. Eventually, the white or gray frame starts two frames later than it should. I built this as a 720P/60 sequence with non-drop frame timecode. I have tried all I frames and the same issue occurs. The GOP structure does not seem to have an effect. There is no audio in this stream. It as if it cannot handle the quick and short transistion from white to black. There are some advanced settings for MPEG 2 but I cannot see where they are explained in the Premier help document. I need this stream to measure latency on a piece of video equipment.
Thanks
Ralph

Bill,
Your answer gave me a hint to what was happening. I'm fairly new to Premier and took for granted that the preset I chose at the begining of the program would carry through to the sequence, wrong! I found another discussion that talked about resetting the properties of a sequence. I expanded the project box a little and saw that it said my sequence was 59.94 frame rate not 60. I followed the instructions on the other discussion. File, new sequence, general, editing mode, and frame rate. The frame rate was set to 59.94 not 60. I reset it to 60, closed all the menues and deleted the original 59.94 sequence. The new sequence I just created shows a 60 Hz frame rate. I exported my lip sync project as an MPEG 2 transport stream and it was correct according to our MPEG analyzer.
Thanks again for the help.
Ralph

Flash Frames On Incoming Video

I have the strangest problem with flash frames I've ever seen. Whenever I make a cut at a scene change in my footage I get a flash frame on the incoming cut. I immediately assumed it was a field so I lopped off the first frame and... no luck. I actually have to tim off the first 3 to 4 frames! to rid the cut of the flash.
My sequence of events: I ripped supplied footage from DVD using Handbrake & de-interlacing into an progressive, Mpeg4 file. Then, using Compressor, rendered it into a progressive, ProRes 422 HQ Quicktime. However, the ProRes 422 HQ Quicktime had this bizarre brightness change when I hit play in FCP6. It was annoying so I used compressor again to transcode the ProRes 422 files into progressive H.264 Quicktimes. They seem to play & edit fine... except for this issue. Unfortunately, this issue is a showstopper. There's no way I can continue to edit with this media doing this.
I've searched the forum for similar posts but none of the problems ever seemed solved, and certainly none of the solutions suggested are working for me; I've trashed preferences, trashed rendered files & re-rendered them, etc. I have zoomed in to verify that there are no extraneous frames. Also, if I import the ProRes 422 Quicktimes and edit with them, they don't seem to have this flash frame issue.
Anybody else seen or heard of this issue? Why would an errant field exist across 3-4 frames? Anybody have any suggestions? Any and all help would be greatly appreciated.

Handbrake is the wrong tool for this...MPEG STREAMCLIP or DVDxDV Pro are the better options. I use DVDxDV...REALLY good with non-Hollywood movie type DVDs. Can extract to DV or Uncompressed...whatever you need. MPEG-4 like H.264 isn't meant to be used as an editing codec, it is designed for final delivery. That might be why you are getting the odd flash frames...the way it is compressed.
As for ProRes brightening...that means that your system needs to reduce the quality of the image in order to play it back without dropping frames...that is one symptom. Another is really low quality playback. To see what you really working with it is good to have a capture card and external monitor connected so you can tell what things really look like...as the computer monitors are playing back a low res proxie.

Fcpx with magic bullet green and pink flash frames

Hi I'm using fcpx with magic bullet. all recent updates. an imac 3.4ghz 32gb ram 512ssd drive and 512mb card. I keep getting pink and green flash frames whenever i colour grade in magic bullet.
first 22 secs of project were fine, next day I added to it, flash frames everywhere throughout the entire project. tried everything. is it a bug?
cheers

This problem is completely averted, for me (and reportedly most others), by exporting using "Send to Compressor" rather than using any FCPX presets. That is, no flashes or green/purple/upside-down frames show up in the final output.
I would hardly have believed that the "engine" used in Compressor is different to FCPX - but that is obviously (simplistically) the case.
This is also some confirmation that the problem is with FCPX - not the plugin.

Red flash frame

Hello,
As instructed in this thread, I've started a new thread regarding this problem.
I work as an editor at a channel with Premiere CC 7.2.1 installed as our NLE. We have several 27" iMacs, 21" iMacs and about a dozen MacbookPro's.
We have experienced the red flash frame several times. It has appeared on MXF and ProRes exports. In one case, (using a MacBook Pro) it was generated on a ProRes export, but not on the low res proxy (unsure of format, will update as soon as I know) that is generated when we export to Sienna.
Red frames have also been introduced on MXF exports from iMac's (i7 27"), via ethernet to an Isilon.
I've taken the advice on the previous thread and told an editor to delete her cache and re-export. She did this and the red frames were not on the new export.
However, we have a high turnaround of news and current affairs content where a red frame may not be spotted. This could happen in a SOT or PKG for news. This file with the red frame could be loaded into ENPS and played out live. As the producer will be viewing the proxy in Sienna, they will not see the red frame as it'll only be on the ProRes, which is in a TX server they do not have access too.
The added danger is that if that section of programming is repeated, it will not be TX'd live from in house, it will be TX'd by a third party. Who (I assume) will pick up the red frame and hit us with a fine.
So, Adobe, is there a fix coming? Or is there anything we can do to ensure this does not happen?

To add, the low res proxy is an MPEG movie at 640 x 360, .mov suffix. No red frames appear on this.

Media Encoder adding flash frame

Using Media Encoder to create a .m2v for use in DVD Authoring. I import a QT, and in the encode, it is adding a random image that occurs about 32 minutes into the program at the 35 minute mark. I reran, with the same result. I have checked the original QT frame by frame and there is no such flash frame in it. Settings are 2-pass VBR, Target Bit Rate 4.2 for a file that is 1hr 43min long. Could Encoder be glitching, and are there any settings I can adjust to avoid it?

I, too, am experiencing Media Encoder throwing in a random flash frame occasionally on an output file. Output specs are typically Pro Res HQ 1920X1080 23.98P with 2 to 8 mono audio channels at 48k and 24bit. These are files for delivery to a client. It seems to be going to some random location within the episode and grabbing a frame and popping it in. Anybody have any ideas as to why this is happening?
We're also realizing this is a random occurrence. Output settings don't seem to matter, and redoing the export with identical settings will yield a file with no flash frame. Sometimes it's there, and sometimes it's not...

What Frame Rate does Catalyst export .SWF at?

What Frame Rate does Catalyst export .SWF at?
When I import a SWF file from Catalyst into another flash program, won't display never mind play, the error I get is that the frame rates don't match,
therefore I need to know what frame rate it exports at?

If you have a SWF created by Catalyst, and you're using that SWF in something you're creating with Flash Builder or Flash Pro, then I think frame rate shouldn't matter. But maybe if you can give more details I could help more... Which flash program are you importing the SWF into, what commands or code are you using to do the import? Is there an error message or alert, if so what does it say? Any info you can provide will be helpful.
Thanks

H.264 export having momentary blip blurs

I have had this issue for the longest time but I'm finally going to admit it on this forum...
Many of my exports in the past have momentary blips of pixelation about every 3 seconds or so. I have made sure that the frame rate of the export matches the footage and that the target bitrate is above 6.
Other settings include:
H.264
custom
1920x1080 (although the issue persists no matter what the number is here)
Lower First
Square Pixels
PAL
Main
Level 4
Take a look at an example. Sequence 04 1 - YouTube
It doesn't happen in every clip. It happens in the first clip (noticeably at 0:03 and 0:06). What could this be???

Version?

Getting choppy footage when rendering plus "flash" frames

Hi all,
I've been using Final Cut Pro 7 for about two years for casual video editing. I use H.264 files with a framerate of 24fps and I always set sequences to fit the native format of the video files I use in them. Today, I noticed an odd "bug" when rendering video files. It's a bit hard to explain, but I'll try my best.
Let's say I take a 5-second clip from an hour-long video file and place it in the timeline. I cut off a bit of the end and add some keyframes to adjust the opacity. I then render this small piece. However, upon playback, the footage appears to "stagger", and even the playhead appears to pause for a moment before continuing on. This is confusing to me, because the footage is rendered properly, so shouldn't it play normally, like the unedited segment of the clip?
I've also had a problem with getting "flashes" of a frame that isn't meant to be in said clip. When I scroll over the clip using the playhead, this "flashing" frame is nowhere to be found.
I'm using Mountain Lion (10.8.5).
Can anyone lend a hand with this? Thanks in advance.

David and Ian are absolutely correct in their posts about the problems with trying to work with h264 quicktimes in fcp. But the issues you are having may also have something to do with your frame rate.
Do you mean 24 fps or 24P? 24p is actually 23.976 frames per second. Most US video is 29.97 fps and 23.976 fps is a relatively easy conversion to 29.97 fps using "pulldown." Early DSLR's sometimes shot exactly 24 or 30 frames per second. New DSLR's now shoot 23.976 and 29.97. Unfortunately, spec sheets don't always describe the frame rate accurately. 24 fps is not a standard video frame rate and there can be problems putting a 24 fps clip in a 24p sequence.
Here's a user tip describing these frame rate issues in greater detail

If any of this isn't clear, post back. It's complicated.

Movie Poster Frames Not Maintained in Export?

I've been setting Poster Frames on all my LR5 videos with the assumption that they would be maintained when i export my videos, using LR5's native export function. I'm now noticing that the poster frames are *not* maintained in the export files. Has anyone else experienced this? I am exporting using H.264 compression, set to Max. I also have checked the option to maintain all metadata in the export dialogue. Any other suggestions?

UPDATE: I noticed that the poster frame of the export is maintained when I view the exported file on my Apple TV, pulling from my home server. But the strange thing is that Lightroom itself does *not* maintain that poster frame when viewing the exported clip within Lightroom. Any ideas why that would be? The exported file is not in the same folder as the original, but that should not make a difference, I wouldn't think. Seems like a bug.

Flash-Frames in Quicktime?

Greetings. I'm exporting a sequence from Final Cut Pro (The project was shot in HDV) to a standard-def Quicktime. I have noticed in the final QT that there are a couple of flashframes in the video. I double checked the sequence, and they are not there, just in the QT file.
Any advice?
Many thanks in advance.
G5 Mac OS X (10.4.8)

did you export using compressor or qt conversion? I would use compressor to do your conversion. look under the advanced formats to select your desired standard def setting. also what can happen is you may have a field that is a flash "frame" i.e. field 2 may be the culprit and you won't see that in your sequence due to the frame based nature of FCP. if you import the standard def conversion you did into a timeline with the appropriate settings and you don't see the flash frames it's due to the frame based situation, if you do see them it's a corrupted conversion. try compressor

Flash frames

If I try to export a six minute movie from FCP through export quicktime conversion and choose MP-4, I get 1/24 frame flash frames randomly through the whole movie (random frames flash through the movie). I've tried exporting through different timelines and different, but all the movies do the same thing. Can anyone help me?
Thank you.

Can you just put the animation into it's own movieClip and
let it play?

White flash frame at chapter start

Hello,
I have a Mac G5 with FCP HD 5.0.4. It came with iDVD 4.0.1. I wonder if you can help me with my problem.
When I create an iDVD project, I get a brief freeze, then a white flash frame at the start of every chapter (scene selection). Same for "play movie" (the automatic chapter 1).
I found advice online pertaining to the same problem with iMovie and iDVD - so I thought I would give it a shot with FCP. I export my FCP sequence (best quality QT movie) without chapter markers. Then I import the single file into a new FCP project, add chapter markers and export it again - to drop into my iDVD project. But no change. Still the white flash frames.
I have iMovie 4.0.1 - but it only does short movies. My project is about 60 minutes.
Do I need to upgrade to iLIfe, DVD Studio Pro, iMovie HD?
Thanks,
Mikado1

Hi Sue,
Thanks for this.
Two problems. First, I don't have iMovie HD - I have iMovie 4.0.1.
I tried your idea (with a short clip). I exported QT movie from FCP HD (best quality, no chapters) into iMovie. Then I exported the no chapter QT movie iMovie to desktop. Then I imported the QT movie to an iMovie new project, added chapters and created an iDVD project from iMovie.
Same problem. I never get to the burning stage. The "freeze then flash frame" problem at the beginning of all chapters is in the preview.
My iMovie 4.0.1 doesn't accept my 60m film (too long) - so I'll need another solution anyway.
I tried reinstalling iDVD 4.0.1 - but still the same problem.
At this point I'm willing to upgrade to something else. Sounds like I'm better off with iDVD vs DVD Studio Pro, given my current knowledge. I shouldn't need iMovie HD, if I have FCP HD already?
By the way, the QT movie export of my project plays fine with QT player.
Thanks so much,
Mikado1
