Frame Blending is Causing Stuttering

I've actually been having this problem for about a half year now (ever since Apple released a past update to Final Cut Pro) and frame blending started behaving weird after that. The bummer part is that all the NEW videos I've made after the update, using frame blending, work great and blend beautifully. But all the videos that I started working on before the update stutter miserably.
The biggest problem is that I have one project in particular (a 6 minute music video) that literally took me about a month to make and it's FULL of slow-mo shots with frame blending and it would have taken me FOREVER to re-capture the footage and start a new project with the updated FCP architecture.
I feel like there has to be a really simple solution, like a field is off or the FPS is off or some little thing that got messed up in the update that I just need to switch back but I haven't the foggiest what it is and I haven't been able to track down any good info on google about this yet.
My "solution" for now (if you want to call it that) is to just take Frame Blending off of all 135 slo-mo shots (which makes it look WAY less smooth, but it's better than constant stuttering). I never posted anything about this in the past because I was always expecting apple to finally release a fix but nothing has ever come out.
As a side note, the stuttering only happens once you render the effect. It looks wonderful in the preview. But in order to export it in any way shape or form (whether to Motion or as a video file), FCP needs to render it - at which point it goes wacky.
Does anyone know any things I could try? Like maybe a way to adjust the source file that all the clips are cut from? (all the clips come from one big DV file)
Any ideas would be welcome.

Okay so here's what happened. First I tried the de-interlacing filter... but no luck. So then I tried the Field Shift Filter in the Video Filters menu, in both +1 and -1 modes... but no luck. Then I thought I'd try re-ripping the .dv file from the clients original DVD (the only reason I never did this in the past is because it originally worked when I made the video. It was only after an apple update that I remembered it no longer working correctly.)
Not really thinking it would make a difference, but following your advice none the less, I recaptured the video and... it WORKED! 6 months it's been doing this, and to think all I had to do was re-capture. One weird thing it's doing now though is the upper letterbox border is "fluttering" at around 30 times a second. My guess is that the letterbox is slightly higher on one field then the other, but that I can just fix with a little minor cropping of the top line of pixils. At least the slow-mo's are nice and smooth again.
That Hobbes face is very fitting... as I feel like that's the face he'd be giving me right now.
Thanks for giving me all the great ideas Patrick, YOU ROCK!

Deselecting frame blending for an entire project

I figured I would ask here before I started and extremly lengthy process.
I have a full hour movie in HD and many clips in it have been slowed down with frame blending. Anyway I just word back from my broadcast people saying that the frame blending is causing wierd horizontal distortion. So I need to turn off the frame blending and remaster my project.
...my question is...If i turn off frameblending by selecting the entire sequence in my master timeline and deselecting frameblending....will that work instead off the mind numbing task of going into the sequences individually and turning off frame blending invidually on...every....single....clip?
Thanks for your help

Guys, I just did a test on this though not in HD my guess is it will work the same. And this assumes your speeds are all the same. Simply highlight a clip hit command-J and uncheck the frame blending. Now that you have it on one clip then highlight the rest of your clips. Control-click and select paste attibutes. Check the "speed" box click okay and you will have lost all the frame blending on those clips.

Adobe Media Encoder 4.2 update forces Frame Blend

I didn't really want to repost, but I felt the title and info in my previous post were innacurate (http://forums.adobe.com/message/2576915#2576915)
In my previous post, I thought Premiere was to blame, but after a few reinstallations, I've found that the update to AME 4.2 causes the problem.
I've found that Adobe Media Encoder 4.2 forces Frame Blend, even if it has been disabled on each clip of the timeline, when the frame rate of your sequence settings differ from the frame rate of the target format.
Example: Exporting from 24fps Desktop -> MPEG2-DVD (23.976fps)
Adobe Media Encoder 4.1 does not have this behavior. I've reverted to 4.1 for the time being.
If anyone has a workaround for this, or any other info on this problem, please share.

I am having a similar problem. Is it just me or is it Adobe? I have had so many problems with Adobe Premiere CS4. It may have also been exacerbated by the fact the I updated to 4.2.1 (mostly in part to determine if another issue was resolved with this update).
I have some editing background in the Windows Movie Maker and iMovie world, and was excited to use Adobe Premiere, but I have had nothing but problems.
Everything that I am trying to do, looks really washed out, and renders the video useless.
I am trying to do what you just described, with speeding up and slowing video to match the computer actions with the person's voice. I am capturing video using CamStudio and Helix YV12 CODEC, and tried to use HuffyUV lossless compression: using DV-NTSC as the standard format.
Then I go to compose my video, and output the video, but the video is crap. It sounds like the Adobe Premiere and Media Encoder are having major problems.
I tried rendering it to Uncompressed Microsoft AVI with UYVY @ 100% quality, and tried to compare it with Windows Media at the highest quality, and it is frustrating. When I hear that Frame Blend is being applied, it seems to look worse.
I am running:
Intel Core 2 Quad CPU 2.33 GHz (which is kind of slow)
8 GB RAM, 2 SATA 1 TB Drives WD Caviar Green (a little substandard)
Windows XP 64-bit
Let me know there is another process that I am missing. I don't really want to give up on Adobe Premiere, but from a end-user standpoint, I will have to revert back to using WMM due to time constraints. I want to take full advantage of all of the editing and effects capabilities of Premiere, but can't because I can't even produce a decent export to be used by any other program (and given that every conversion will in some way affect the quality of the output, I want to reduce any intermediate steps).
Arrggh!!!

Frame blending not blending propperly

Problem is this:
A clip is slowed to 20% with frame blending enabled. However, when it's played back, it looks jerky, as though there were a problem with the frame rate.
The clip is MPEG4, 30fps. The sequence is also set at 30fps.
This is what it looks like:

Turning frame blending off doesn't result in change (unless an effect is applied)

Hi!
I have several fast speed clips on my timeline and I need to turn off frame blending in order to avoid the blurriness caused by that setting.
However, when I turn frame blending off, it has no effect on the clip -it stays just as blurry as before. I discovered a workaround which is applying an effect on the clip that does nothing but still forces premiere to re-render the clip (like curves for example, without changing any parameters). But that's only a workaround and I wouldn't like to have to put an additional effect to every single clip that I have with fast speed. Is there a better way to get Premiere to re-render the clips without frame blending? I tried to render the whole work area again, but still the frame blending persists.
Any help will be appreciated!

Just some speculation here as I'm not a network expert.
I don't think it has anything to do with WIMAX, only with communicating with the dhcp server of your device.
Your 169.254.x.x IP is not an IP given by a successful connection, but only a dummy given when the true connection fails. (someone please explain this more accurately )
Work thru the wiki setup page again. Note the dhcpd setup section and the note on your realtek card.
http://wiki.archlinux.org/index.php/Configuring_network
Try the Arch driver again for your card.
Or, switch to the netcfg2 setup, even though using an ethernet card, it works great for my setup with a realtek card.
It can be found http://wiki.archlinux.org/index.php/Network_Profiles here.
Hope it helps.

Frame Blending

I have two questions. First, I am about to export a film with some slow motion in it. Will it be detrimental if I frame blend the entire film upon export or should I go ahead. If not, I could export the slow motion parts with frame blending and put them back in. Just wondering what's best.
The other question relates more to pixel blending. We have used the de-noiser very heavily on some shots causing a blurry static flutter in them. I was hoping frame blending might help that, but it appears to me it doesn't apply to anything but time adjustment. Any ideas on how to alleviate that flutter?

which de-noiser effect are you using? if its causing a side effect, then it would be better to use another de-noiser, rather than try to fix a problem it creates.
premiere has no real slow motion effect. it will either duplicate frames or frame blend. neither are good options for todays fast refresh rate monitors. if you still want to use frame blend, you can select the slow-mo clips in the timeline and right click to turn on frame blend just for those. if you have access to after effects you can try the one in there, or look at third party plugins like twixtor. if you shot high fps like 60, you can then slow mo that footage and premiere will have frames to work with, and wont need frame blend.

Frame blended interlaced pulldown frames...

Having an issue with telecine transfered footage (29.97 fps, NTSC) going through color. When it renders out I get a strange frame blended ghost image to any areas of motion. I have tried de-interlacing and not de-interlacing my renders to no avail. No color effects are being used.
The interlaced pull-down frames are the only frames with the shadow image.
Thanks in advance.

Did you reframe any shots in FCP? If so that info gets translated into Color's Geometry Room and cause problems. The following is a workaround.
Prep sequence and send to Color (or export/import EDL) as before.
Leave P&S settings untouched and do your grade
Save an archive of your project within Color
Remove geometries, save, close, reopen, render grades.
Then reload your archive within Color and send your sequence back to FCP (or export and import XML).
When you reload the archive Color will give you a warning about not being able to reconnect the renders (or something like that) but just ignore it.

Turning off frame blending in Adobe Media Encoder

Is there a way to turn off frame blending in Adobe Media Encoder? I have a bunch of
Flip Mino HD footage (1280x720p) which I wish to convert to P2 720p format so that
I can more easily mix and match it in the Premiere timeline with actual P2 footage
shot on an HVX200.
I successfully used Media Encoder to perform this task but there is one problem. The
Flip footage is 30fps and P2 720p is 29.97fps. So Media Encoder uses frame blending.
The frame blending sometimes creates obnoxious artifacts so I would like to turn it
off but there seems to be no way to do this (or alternatively "conform" the 30fps input
to 29.97fps so that no blending is nescessary).
After Effects CS4 would seem like an alternative since it has nice batch composition
creation and rendering features but it cannot render to the P2 format - it appears to
have a older version of Media Encoder embedded within it - predating P2 support.
I would like a solution that is easily "batchable" as I have several hunderd Flip Mino HD
clips that need to be processed.
You might also ask, why not just import the Flip clips unchanged into Premiere CS4
and mix them with the P2 clips?....I have tried this and it seems to drive Premiere crazy
introducing various crashes and other strange behaviors. The pre conversion to P2
route seems to work fine. I just want to get rid of the frame blending.

I happened upon this video just before I made my posting and it doesn't help with the
crashes/hangs. When I import more than about 20 Flip Mino HD clips it seems to trigger
some sort of memory corruption bug in Premiere. Some of the clips start to just
show as solid green in their thumbnail views in the timeline and scrubbing the timeline
eventually hangs Premiere altogether. This is reproducible on two different computers
although the exact symptoms change slightly each time it is tried. Importing only 3 or 4
clips actually seems to work, at least for a short while.
The problems happen even if the only thing imported into the project are Mino footage and
the Sequence is set to Desktop or XDCAM mode. So the crashes have nothing to do
with P2 editing mode.
The same installation of Premiere CS4 on one of these computers has been just used to
successfully edit and render out a P2 project with hundreds of clips, stills and titles so the
basic CS4 installation seems to be solid.
I'll eventually file a bug report but for now I'm more interested in getting the job done.

Is it possible to partially export a video using frame blending?

For example, I have a video intro that, after being uploaded and processed on YouTube, looks very choppy. However, if I export it using frame blending, it looks perfectly fine. The down side is that the rest of the video looks somewhat more blurry, as frame blending tends to do. I like how fluid the intro is when frame blended, but I perfer the rest of the video when it's just exported normally. I found an option called frame blend under the clip's video options, making me think that I could fix my problem, but it didn't seem like it did anything at all when I exported it. Is what I'm trying to achieve actually possible, or will I just have to deal with it, one way or the other?

1. I export in H.264 with the preset HDTV 720p 29.97 fps High Quality. I would use the YouTube preset, but it compresses the audio to a point where it sounds terrible. I'm sure there's a way to fix this, but I don't know enough about it to do so myself.
2. My sequence also runs at 29.97 fps.
3. The intro consists of several game capture clips all .avi at what I think is 29 fps. Many of the clips are sped up to at least 200%.

FCP turns off when I turn off frame blending

Hi, I really hope that someone can help with this. I'm running FCP 5.1, 8 GB, 2.66 Ghz. Just starting yesterday, everytime I keyframe a move in the motion tab, as I click to turn off frame blending, FCP quits. No "app unexpectedly quit" warning or anything. Just shuts down. It's pretty annoying when you're on a deadline.
Anybody have any ideas? Please feel free to step up to the plate. Thanks!

Did you do any software updates recently? You should always clone your startup drive when you have a stable OS/Application combo. This way you can restore your system to it's previous state quickly.
Have you repaired permissions?

"lower than intended output quality: frame blending DISabled"???

When I print to tape, after all conforming processes have finished I get
"Note: The following conditions exist in this sequence which may result in lower than intended output quality.
The following can be adjusted using the Render Control tab in the Sequence Settings:
- Frame Blending For Speed is disabled"
??? Frame blending, if anything, will lower the quality even further?
And, if I turn ON frame blending the warning does not disappear but I get the additional warning
"There are sections that are rendered at proxy quality"

Unwanted frame blending look after transcode

For some reason,
When I burn a DVD in Encore and play it on a TV or a computer (anything) it seems to have a frame blending look where if you pause the DVD at any point, you will see two frames blended together like they are both at 50% opacity. I have no idea why it looks like this. Also, when scrubing through the video in Encore after it has already been transcoded, I will see the frame blending. And if it has not been transcoded yet, I see no frame blending.
I work on a PC with CS3.
I use the recomended transcode settings everyone recomends (23.98 for 24P footage, progressive, CBR 8, and the file is AVI)
I also played the original AVI file to make sure it wasn't an issue before the transcoding/burning in Encore and it looked fine (no frame blending look).
Please help me out if you can, I am about to enter my film into festivals and want it to look the best it can.
Thanks!

IIRC, En CS5 changed a few default settings. I do not think that those were eliminated, just the defaults from OFF to ON, or ON to OFF were added. Likely one of those settings made the difference. Do not recall if any of the Frame Blend options were in that group, but they could well have been.
Glad that CS5 made the difference for you, and good luck,

Frame blending issue in timeline

For some reason the video in my timeline and in the canvas has the previous frame blended into the current frame (every other resolution line). This makes the picture choppy with horizontal lines especially with fast movements. This issue doesn't show up when I put the video in the viewer but it is still there when the final project is exported. I have tried to tweak with the settings for a long time now and I haven't had any luck. Does anyone know how to fix this issue? It's driving me insane!

Al,
This clip is raw footage captured from a miniDv tape. But I have this issue with High 8 and other sources. The only format that doesn't seem to have that issue is DV from dvd clips that I ripped.
This Sequence properties:

Frame Size: 720 x 480
Compressor: DV/DVCPRO - NTSC
Dat Rate: (blank)
Pixel Aspect: NTSC - CCIR 601
Anamorphic: (not checked)
Field Dominance: Lower (Even)
Alpha: (blank)
Reverse Alpha: (not checked)

I just noticed that this issue doesn't show up until I drag the clip into the sequence. If I just double click it from the browser into the viewer it looks perfect. I have a screenshot of this issue if it helps, I just don't know how to upload it into this message.
Thanks for your help!

''field option" settings and "frame blend" now the motion is stilted!!

Hi there! I messed with ''field option" settings and "frame blend" trying to improve some already very low quality footage - and now the motion is playing and exporting stilted/jerky..!! Any help or suggestions would be very much appreciated!! does anyone know how to revert back or increase smoothness in motion smooth - it's too late to undo... Frame blend doesn't work! Thank you!!!

Hi Ann,
Thank you so much! - clearly I'm a novice. great lesson back to smooth motion. Thanks again for your help!
