To Frame Blend or Not?

Hi All
I exported some quicktimes to go to tape the other day. The Behavior Glow effects looked a little steppy. I was wondering if Frame Blending would have fixed that.
I can't tell at home on my flat csreen but it was apparent on the CRT where I was doing the playout.
Any advice would be welcome.
Cheers Tim

Thanks Peter
Yes, I had field render and had motion blur on.
It just didn't seem right to put frame blending on.
I'm wondering if this is the way Motion does smooth light effects.

How to change the speed of a clip without frame blending?

Hi,
I changed the speed of a clip to 200%. I expected Premiere to drop every second frame. Instead, there is some frame blending making my progressive footage interlaced. For some reason, the frame blending cannot be disabled by using the Use Frame Blending option.
How can I make Premiere simply dropping every 2nd frame?
Thanks in advance!

In my test, all I need do was right click the clip and make sure Frame Blend was not checked.

Frame blend unaffective?

Hi all,
Here again, once again stumped with Premiere's unwillingness to work properly/consistently and unable to find any other forum threads about my problem.
What's going on is that the clip option "Frame Blend" is not seeming to have any effect on my render in CS4. In fact, when I take on and off, the state of the render remains the same. In other words, if I've rendered and it's green, I turn off frame blend, and it stays green. Turn back on, and it stays green. It's pretty obvious it's just broken-disconnected from affecting my clips, as it renders like a charm, quickly, and in the amount of same time whether or not Frame Blend is checked or not--and the playback of the render is clearly frame to frame. For example, if I slow it down to like 10% it's, step.... step... step... or about 3 frames a second.
The project is SD, the footage is HDV captured in Ppro as mpeg, it's on a OS X 10.5.6 .
Here's the kicker, the same project copy/paste from CS3 works just fine. No changes what so ever and my render time shoots up (as expected) and it actually renders the Frame Blend, producing smoothe video.
I would just export the whole thing out of CS3, but CS3 particularly likes to crash randomly through the export (I've tried a variety of output formats and the standard copy/paste into a new project, timeline, etc). Which is the reason I decided to take it to CS4 to begin with.
I'm going to try the last update for CS4 which apparently has to do with AVC-Intra.. but in the meantime I'd appreciate some help and advice.
Thanks!

I'm fully up to date, that was the first thing I tried to no avail. I was surprised that updating didn't fix it, I was expecting it to.
SFL, I had searched the forums and came up with nothing, hence my post beginning with 'unable to find any other forum threads about my problem'.
I'll mention again that a) the clips that aren't working have time remapping applied or constant time speed changes. For example, one clip variables from anywhere from 10% to a 80% or so speed change, and many of the clips have been stretched with the stretch rate tool to fit gaps. I wouldn't be able to tell if frame blending was working or not if the speed wasn't changed and still at 100%.
And b) frame blending is working fine in CS3. More details on this are above in my earlier posts, but basically the exact same sequence works in CS3 but doesn't work in CS4. So the circumstances haven't changed between it working and not working.
My vote is some sort of translation bug when updating a CS3 project to CS4. It also messed up a variety of other things (mentioned above) that made me decide to just go back to CS3 for the project and deal with the random export crashing.
Typical week using Adobe products powerful and sloppy. Thanks for the responses all,

Frame Blend Default? & Recompress as Default?

Does anyone else feel that 'Frame Blend' should NOT be the default mode in Premiere? (Its a real pain in a world of 'progressive footage")
Similar question - Why is Recompress the Default Mode?
Anyone want to change either/both???

Vote: Serious mode On
in my humble opinion You should be as flexible as possible
Serious mode Off

Frame blend for default!!!

Hi I'm using Premiere from ever...but I'm very angry that now frame blend is not selected for default anymore... So I'm working everytime with pal 576i sequence...and I edit all my clip with speed at 70 or 60%, for rallenty. So I have to add the option "frame blend" manually to every clips that I put on Timeline! Beore Cs5 "frame blend" was activated on every clip that we put on every sequence. So can you add the possibility to make "frame blend" by default to every clip on the preferences menu of Premiere or better on preferences of new sequence! I think that it's very IMPORTANT! P.S. There's also a bug...if I select any clip in project panel and select there "frame blend", when I take these clips and put theme on sequence "frame blend" will not be selected anymore. Thanks!

Hi all,
Just a small quick comment. In past PP versions you could not turn frame blending off except for going though each and every chip in you project. I think the is why people preferred to have it turned off in the first place. This is a downfall so to speak in the PP software as a whole. There is just so much time wasted doing routine boring tasks like this one and others. I don't thnk adobe software is written that well. Some parts are nice but others could be a lot better. Like incooperating a slow-mo eding feature that incooperates the shuttlepro to create an action to record the slow-mo in real time. I have done this by taking my video camera and recording the screen of my actions using the shuttlepro and the jog dial to precisly show the slow motion. I can easily run the clip in slow forward rewind at just about any speed and play it again. This is what slow-mo recording should be. And ths is partly what i am talking about. Back to the subject. A computer is good for one main purpose, to perform these boring routine tasks and a computer can do it well leaving the editor to concentrate on the creative process. For those of you that have a iPhone 4 or 4s or an ipad1 or iPad2 check out both iMovie for video and Photoforg2 for photo editing. Photoforge2 in particular will give you an idea of what I am talking about when I talking about powerful ease of use software. Also iMovie shows this point and I will give a short example...
Say I want to email a 1080p video. Imove on the iphone tells me that the movie is to long/big to send. Instead of having me the user cut down and edit the movie to the right size imovie does the work for me and lets me confirm the resulting movie. I can use a slider to adjust the portion i want to send. Also imove compresses it and put it in the right format to send. These are all, things that are time comsuming for the user but a computer and well written software can perform well.

Frame Blending Not Respecting "Anchor" Frames

I have a QT movie. It is 24 fps. If I drop it into a 48 fps comp and step thru one frame at a time each frame repeats twice.. makes sense (A-A-B-B-C-C). But if I turn on Frame Blending (both Modes) not only does the repeated frame get re-created (A-AB-B-BC-C-CD) from interpolation but the KEY frames get altered too ... what's going on? Why is that? Shouldn't the Key frames - the 'real' frames be unchangeable anchors? 48 is twice 24 so those shouldn't be getting blended at all in the first place.
I've tried Time Remapping instead of a higher frame rate comp and also the Time Stretch flyout to 200% - each gives me the same results.
Any ideas what I'm doing wrong?
Marc

Honestly, that doesn't jibe with me. Even if it looks 'backwards' ... take the B for instance in my example ... the previous frame generated would just get it's info from A making AB before B. But I digress - it is what it is but I SWEAR I've generated 60i fields from 30P without altering the Key frames in the past.
But something you said started me thinking. Twixtor. I don't have a few hundred bucks for Twixtor so that was out. But when I picked up Mark Christiansen's book he mentions in his discussion about frame blending that while After Effects doesn't come with Twixtor it DOES come Timewarp from RE:Vision so I looked into that...
and it worked.
There's a teeny tiny button called, "Build From One Image" that keeps the Key frames whole and makes AB frames in between as I would expect. (See! I'm not the only one who thinks it should work like this. .. ... they made it a FEATURE!)
So I got what I was looking for with Timewarp.
Thanks to Mylenium for the Twixtor hint and Mark for his great reference book.

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:
http://www.wpsc.co.uk/teleport/slowmoproblem.mp4
Any help would be awesome!
Thanks!
Ben

I've actually been having this exact same 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.
Any ideas would be welcome.

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!!!

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.

"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!
-Daniel Soderberg

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:
Vid Rate: 29.97 fps
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)
Composite: (blank)
Clip Properties:
Vid Rate: 29.97 fps
Frame Size: 720 x 480
Compressor: DV/DVCPRO - NTSC
Data Rate: 3.6 MB/sec
Pixel Aspect: NTSC - CCIR 601
Anamorphic: (not checked)
Field Dominance: Lower (Even)
Alpha: None/Ignore
Reverse Alpha: (not checked)
Composite: Normal
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!

Question on Whether to Check Frame Blending & Use Previews in AME

Hi, When I export a project for transcoding, there are 3 boxes at the bottom of the menu selctions. One is "Use Maximum quality." I ckeck that. I am unsure as to whether I should check, "Use Previews," and of "Use Frame Blending?" I am encoding Mpeg 2, 1080p, Max quality, 80 frame rate.
Thanka Roman

"Use Previews"
No. That's only if you want to use rendered previews as the source for your encodes. About 99.99% of the time, you don't want that; it will result in lower quality exports, as you're using "precooked" files.
"Use Frame Blending?"
Depends. This is a global switch that you may or may not want to use when your export has a different frame rate that your source sequence/footage. It forces frame interpolation (blending) using two or more discrete frames to create new frames. The exact times you'd want this vary depending on your destination and preferred output look.
The help docs say this about Frame Blending:
Select Use Frame Blending to create smoother motion
by blending adjacent frames when output frame rate doesn’t match
input frame rate.
Smoother motion, yes. Blurry video, sometimes.

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!

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.
