Possible Pixel Aspect Problem - PE7

I'm a newbie to video editing.
Widescreen (16:9) DVDs that I create with Premiere Elements look correct when played on my PC with the Intervideo DVD player but are horizontally scrunched to 4:3 when played with my DVD player on my widescreen TV.
In brief, the process is
AVCHD video from a Canon HF11 is imported into Premiere Elements 7 using the AVCHD 1080i Full preset.
The edited video is then burned to DVD useing PD7 using the Dolby NTSC Wide option.
I have two PCs which have the Intervideo DVD player installed. The DVD is displayed correctly on those but when I put it in my LG DVD player and play it on my Sony HDTV, I get scrunched 4:3 output.
Where should I look for the answer to this problem

Hi Kevin,
Are you ENTIRELY SURE that the settings on your LG DVD player are
correct (i.e. to output a 16:9 display)? Here`s the crucial que-
stion : IS IT CAPABLE OF RECOGNIZING AVC-encoded video burned on
a DVD ?
DVDs with AVC-HD burned on them, basically function like their
analog counterparts from the standard definition era, the VHS
cassetes. We are talking about SERIAL playback of video, no
interactivity like that we are used to, when playing back a DVD
or a Blu-ray with menus.
If your LG player is fairly old, it may not have been designed
at a time when AVC-on-a-DVD (i.e. the cheap, home-made alterna-
tive to authoring High Definition disks as opposed to Blu-ray)
was NOT thought of (and later materialized, much like the famous
3xDVDs, i.e. HD-DVD material burned on standard DVDs and designed
for playback on HD-DVD players).

Pixel/Aspect Ratio Problem

I'm midway through a huge project utilizing about a hundred stills in NTSC SD. I needed as much screen real-estate as possible for this so I used the D4/D16 Anamorphic pixel aspect ratio in Project Properties. My problem is that because I don't have a Kona or Decklink card, I don't have any preset codecs for this aspect ratio when I take it into FCP 5.1. The result is a squished widescreen frame when I output it from Motion to FCP. Not sure how to resolve this. Do I give it a custom frame size in FCP or what? Also, because this is all photos and graphics made within Motion, what's my best option in terms of quality for export from Motion to FCP? I'm assuming 8-bit or 10-bit uncompressed, but that's just a guess. Or is there a codec within Motion that I can export it as and it will come out in the correct aspect ratio in FCP?

Then I'm thinking you want to use an anamorphic widescreen format in FCP that you can then set up in DVDSP and presumably project or display on a widescreen TV...

Problem with pixel aspect ratio

I searched but found no answer.
I have several Maya renders which are at a resolution of 720x486 and a pixel aspect ratio of 1.2. I composited my image sequences in after effects interpreting that 1.2 pixel aspect ratio. I then exported a quicktime movie using no compression at 24fps at a resolution of 720x480 NTSC 16:9.
When I import this video into Encore 2.0 It comes out as full screen. Not only is it full screen, but when I preview the dvd, the video is blurry with scan lines and black bars on the left and right side. The menu however, is widescreen (I used a template as a test)and perfectly clear. I tried to select the asset and go to file>interpret footage, but this option is grayed out. I have also tried exporting an avi from after effects and importing that into Encore. It still will not let me set the pixel aspect ratio. I have read that After Effects does not embed the pixel aspect into exported videos. I have also read that I should export mpeg2 videos for use in Encore, however I do not see this option in After effects or Premiere Pro.
What am I doing wrong? Any help is appreciated. If I left any information out that could be useful, please let me know.

(Ack, for some reason I typed "DVI" and really meant "DV")
Thanks for the response. I don't really care if I preserve the 4:3 aspect ratio. Or does my GL1 not use square pixels and I just never noticed it? It's strange I've never seen this problem until FCE HD.
I have tried exporting a number of ways from FCE, including Export > QuickTime Movie... and Using QuickTime Conversion... For the latter, I typically set it to export as 720x480. I always export as video. The final export contains video clips as well as still images within the video.
I am a bit embarrassed having to ask this question. I've been working with still images in photoshop for over a decade and worked a lot with video during that time as well.
Thanks again.

Has anyone else encountered a problem with poster frames not recognising a video's pixel aspect ratio

I'm discovering a strange effect with some of the .mp4 videos I've upload into iBooks Author. They're Pal SD 4:3 .movs with a 16:9 pixel aspect ratio and they play out fine on the iPad. However the iBooks software seems to be ignoring the pixel aspect ratio of the poster frame. This leads to the situation.
1) When I drag my video into iBooks author all looks good - the video is 16:9 and if I choose to set a poster frame (or leave it at default) it looks 16:9 in the iBooks Author.
2) I preview my book and it opens in iBooks on the iPad. But now the poster frame aspect ratio is 4:3
3) I click on the video to start playing and it immediately jumps to 16:9 aspect ratio and plays out fine.
4) If it scroll down a couple of pages and then scroll back the video poster frame has now reset itself to 4:3
This sounds like a bug to me. Anyone else had it? Do you know if it's possible to report bugs without having a Developer licence?
Thanks for any help
Rob

While there is no formal bug reporting method similar to what devs have w/apps, iBA does have a 'Provide iBooks Author Feedback' menu item.

CS5 Pixel Aspect Ratio Problems...

Hello All,
I am working on porting over an existing .mov file importer from Windows to Mac while also upgrading it from CS4 to CS5 (and also rolling in the creation of a hand-written 64-Bit QuickTime file handling library to boot, ouch).
In my current test bed I am having problems with certain 1920 x 1080 .mov files. Some 1920x1080 files that I have get imported properly, some files that I have get imported with the wrong aspect ratio. I have verified that both files should be displayed using square pixels and have also verified that when the selector is sent that calls SDKGetInfo8( ) that I am setting the following for **all** of the above-mentioned test files:
SDKFileInfo8->vidInfo.pixelAspectNum = 1
SDKFileInfo8->vidInfo.pixelAspectDen = 1
I have stepped line-by-line through SDKGetInfo8( ) and the stretched and non stretched clips seem to yield exact same traces through this function. However, the files that are being imported with the wrong aspect ratio, of course, preview in a stretched format. Also, in the informational area of the Source Bin, when the *stretched* clips are selected the information that is provided for these clips is:
NameOfTheStretchedClip.mov
Video, 1920 x 1080 (1.7778)
00:00:9:13, 23.976 fps
etc…
For the clips that aren't stretched, the (1.7778) is (1.0). I am not the biggest expert on the actual usage of Premiere, so I can only assume given the values displayed and the respective visual result of the clips when previewed that this value displayed in the UI is the pixel aspect ratio and not the frame ratio as the clip with (1.7778) is stretched and the clip with (1.0) is not, yet both are 1920x1080 clips. What to me is suspect is that 1920/1080.0 is 1.7778 and so somewhere for the clips that are being stretched the pixelAspect ratio values seem to be getting derived using the pixel dimensions and not the values vidInfo.pixelAspectNum and vidInfo.pixelAspectDen that are explicitly set to '1' as shown above.
Thus my question is, aside from setting in SDKGetInfo8() the following values:
SDKFileInfo8->vidInfo.pixelAspectNum = 1
SDKFileInfo8->vidInfo.pixelAspectDen = 1
Where else are the pixelAspect values supposed to get set?
Alternatively:
- During which other selector calls *CAN* pixel aspect ratio get set? As I mentioned, I am porting existing code, so perhaps these values are getting set elsewhere that I am presently unable to find.
- Is there some setting that might get set at the import of a file that says to derive the pixel aspect ratio from the pixel dimensions that might be getting triggered for the clips that are being imported as being stretched?
Thanks in advance for any help!
Josh

Hi Zac,
I am taking a look at this issue further with the aid of an additional engineer here that has more experience with QuickTime files.
First off, upon viewing the XMP metadata of the stretched file in the Metadata Viewer available inside Premiere, the Video Pixel Format is, in fact, listed in the XMP metadata as 1.78.
However, the time signature on the stretched .mov file, as listed in information of the QuickTime atoms, was 23976 / 1000. On a whim we used Dumpster to change the time signature to 24000 / 1001 to see what would happen. After altering the time signature in the Atoms of the file in this fashion, in Premiere the aspect ratio is now shown to be (1.0) in the source information in the Source Bin and the video is imported in the proper unstretched format (or - better stated - played back via our PlayMod in the proper unstretched format). However when viewing the metadata in the Metadata Browser in Premiere, the "Video Pixel Aspect Ratio" is still showing 1.78. This seems to confuse the issue further as now this time signature alteration in the Atoms of the QT file has fixed something and is now seemingly overriding the order of operations you mentioned as the XMP metadata still seems to list an improper format, yet everything else is seemingly behaving fine.
BTW - Clips with other time signatures don't seem to have this problem.
Any ideas?
Thanks,
Josh

H.264 pixel aspect ratio problem after update

Yesterday I updated Premiere Pro CC and Media Encoder CC to version 2014.2. But now I am having pixel aspect ratio problems with the H.264 codec when I export a 1080i50 sequence to PAL widescreen. The problem also seems to occur with other frames sizes.
I am using the same settings as usual with Aspect set to: D1/DV PAL Widescreen 16:9.(1.4587). However, VLC and Windows Media Player play the video with a 5:4 ratio. So it looks like the pixel aspect ratio information is not passed to Media Encoder or to the file.
This problem does not affect other codecs like AVI or MPEG-2, these are correctly displayed.
Is there anyone else having this problem? And more important, does anyone know a solution?

When creating files for computer/online playback (not editing), then best practice is to simply use square pixels with 1.0 Pixel Aspect Ratio, which will ensure that ALL players correctly display your video, no chance of problems.
Export as 1024x576 with 1.0 PAR and that is the square-pixel equivalent of PAL DV widescreen.
For NTSC users, I've seen it two ways, either 864x480 or 854x480.

Exporting 1080i, Pixel Aspect Ratio Problems

Hello everyone,
I've been dealing with a lot of different format projects recently: SD, HDV 720-24P, and HDV 108050i.
For now, these projects are intended for internet delivery. I've not had too much problem exporting the SD and HDV 720-24P projects, but the HDV 108050i has been very frustrating.
When I export SD and HDV 720 in compressor, I set the pixel aspect ratios to NTSC and square, respectively. But when I try to set the pixel aspect ratio for the 1080i to "1080i 16:9" (which I believe is 1.333:1), it rejects my choice, choosing "default" instead. When compressor finishes exporting, my 1080i movie looks very squished horizontally.
The only success I have had is in exporting via Quicktime conversion, where I duplicate my compressor settings, but do nothing to the pixel aspect ratio (since there is no option to change it in quicktime, it seems). The movies I have exported with Quicktime have been fine. I don't know if it makes a difference, but when I try to export these 1080i clips, I am in the proper 1080i "easy setup."
I know almost nothing about this pixel aspect ratio business, but I believe it is the cause of my problems (since I am using the proper 16:9 aspect ratio for movie width x height).
My Questions:
1. If I am understanding the problem correctly, how do I get compressor to acknowledge the right pixel aspect ratio for my 1080i footage, rather than the incorrect "default"?
2. If am not understanding the problem correctly, what might be going on?
3. Can anyone point me to a useful resource about pixel aspect ratios? I've been searching the forums and online, and I thought I was getting a grip on things but it seems I am still way over my head. For example, what is the significance in Final Cut Pro of changing your viewer or canvas to not show square pixels? Do you need to format for square vs. non-square depending on the final delivery destination (not the source format)?
Thanks!

Premiere exports in incorrect pixel aspect ratio

My Panasonic camera shoots quicktime .mov JPEG videos in a 720X408 px resolution. I am having a very hard time editing them in Premiere, because I cannot get it to export them in a correct pixel aspect ratio.
Maybe you can figure out what I'm doing wrong. Here's what I do.
First, when opening a new project, the closest frame size I can choose is 720x480. So I choose that. I import the .mov file into it, and put it on the time line. At that point it looks like this:
http://img291.imageshack.us/img291/812/premierewindowoc9.jpg
Correct aspect ratio and no deformation.
When I try to export it as a .mov file, I do the following: I click on settings (in the file save dialogue), and go to video settings. I can choose any pixel aspect ratio, it all produces the same results, but for example, let's say, DVCPRO (1.5) (that's the closest to the size I need).
I can manually set my frame size to be 720x408 px, assuming that now the frame size will be exactly the same size as my video and no deformation will occur.
However, the result I get is this:
http://img6.imageshack.us/img6/6730/exportedmoviehl5.jpg
I've drawn arrows on that to make it clearer. So, I have a movie that's 720x408px. Premiere exports a frame sized 720x408, but then for some strange reason shrinks the actual video down to 483x480!!??!! Leaving completely unnecessary black bars on the sides.
Why does it do this?
When I export it with frame size 720x480, it doesn't add black lines on top and bottom as you'd expect. It does exactly the same thing you see in the image above.
I have tried many other combinations too. I have tried exporting it as every other available pixel aspect ratio, also as an avi file, nothing makes any difference. It always shrinks the original video in width, and adds black bars to the left and right.
What am I doing wrong??

Tina,
Lets see if we can get kitty onto YouTube.
There are four issues, that you will need to overcome:
1.) Project Preset to begin. Stanley lists the possible choices in post #8, based on the specs of your camera. You will have to determine which of these you used to record the files. These are *probably* set in your cameras menu area, and if you have not changed them, are probably still set. That will get you started in the right direction - but wait, theres more...
2.) It seems that your camera uses Motion-JPG as the encoder to create these files. There are at least two good Motion-JPG CODECs available, Lead and Morgan. Plus, your camera may well have come with its own Motion-JPG CODEC. The CODEC is what allows your camera to encode/compress the video data, and also what allows programs like Premiere to decode that data. Did your camera come with a CD/DVD with software on it? If so, the installation of that software *should* install any proprietary CODECs to your system. Now, if this was the case (or soon will be the case, when you locate that CD/DVD), Premiere *possibly* will be able to use that CODEC to handle the footage from your camera. If it does not, then it is *possibly* only a matter of purchasing, downloading and installing one of the two mentioned Motion-JPG CODECs. Both are relatively inexpensive, and Premiere *usually* can work with either, though your exact footage might not permit this. This is usually because a camera mfgr. chose to do their own thing. Thats why any disc that came with the camera is the first place to start.
3.) Now, you are in Premiere, have the proper CODEC installed on your system, and have Imported the footage into a Project with the proper Presets. If all is working, and I hope that it is, you just edit your footage.
4.) You have been working with Presets established based on your footage. That is likely not exactly what you will want to upload to YouTube. This is where Export comes into play. Unfortunately, YouTube seems to change the specs. weekly. About the time that someone publishes fool-proof details and settings for YouTube, they (YouTube) change everything. The best advice is to search as many fora, as you can for Export Settings for YouTube. Look at the dates for all articles. You really will only care about the most recent - very recent.
Going back up the list, there is another possibility. That would be to use a 3rd party conversion program to convert your footage to a DV-AVI Type II file. Often, with the proper CODEC installed, Premiere can do this internally, though not always, and even when it works, there can be problems. I use DigitalMedia Converter (Deskshare) a shareware program for most of my conversions. There are many freeware, and shareware, conversion programs available. Many get mentioned in this forum. Many get glowing reviews. Some are easier to use, than others.
Some balk at the thought of owning Premiere Pro and then having to use some 3rd party software to get their footage into a robust NLE, that they paid good money for. The fact is that Premiere Pro was designed to work primarily with DV-AVI Type II files, from mini tape cameras - the point made by several. That does not mean that it cannot work with other file types. It does, though not always without problems. Sometimes just passing the material through a conversion program will clear up all problems and no one is the wiser. I often use Premiere Elements, Pros little bitty brother, to convert some file formats, because it is more tolerant of many of these, than is Pro.
Good luck, and sorry that I do not have a current suggestion for Export to YouTube. Since it is a hot distribution medium, you should have no problem finding the correct settings for today - be sure to check the date of all articles, as the specs change all the time and in a heartbeat.
Let us know if you have any more questions. For "how things are done in Premiere," I recommend the Premiere-wikia: http://premierepro.wikia.com/wiki/Main_Page
for tutorials. Most that you could want to do will be there someplace. The current YouTube setting might be an exception, just because every time the Wikia gets updated, that info is out of date.

Pixel ratio problems

I am having aspect ratio problems with digital footage in FCE lately. The footage is shot on a couple of sony cameras (mine is a dcr-hc96) and captured directly into FCE. The footage is shot in 4:3 and I want the movie to be 4:3 to post on YouTube, etc. I have been capturing the clips using the "NTSC DV" setup (via firewire).
The problem is, when I save or export the movies, the frame is stretched. When I inspect it using QT Pro, it shows the size as "720x480 (640x480)" and the display is stretched wider than normal from side to side. Apparently, the image needs rectangular pixels but is using square pixels. The only way I can get a proper frame size is to explicitly export to "640x480 VGA." This has only started happening recently. (Possibly since I installed QT Pro...)
Any suggestions? I looked here and did not find anything directly applicable. The user manual does not help (it says "fortunately, FCE always works with native resolutions so you get the exact pixel dimensions.")
thanks in advance
Powerbook G4
OS 10.4.10
FCE 3.5.1
QT Pro 7.2

+why this would happen...+
When you Export/Quicktime Movie or Export/Using Quicktime Conversion (and you use a DV codec) the resulting .mov file will always have rectangular pixels: 720x480 for NTSC. This is correct and it will display correct on a TV from the video DVD after burning this file.
If however you want to watch the same .mov file on a Mac (or PC) monitor, the player must change the pixel aspect ratio during playback, since Mac monitors are square pixels devices. The corresponding media is not affected by this option, but only the QT Player playback.
QT Player (with QT Pro) should default the Presentation option to: Conform aperture to = Clean, as I wrote in my previous answer: this is telling QT Player to make the pixel ratio conversion on the fly. My guess is that the "Conform Aperture to" option is not properly set for you; if it is not set, or it is set to Classic or Encoded Pixels it will show the stretched pixels. The Production option is almost like Clean.
If you export from FCE to some format other than DV in general its pixels are already square (e.g. H.264 has 320x240) and the Conform Aperture to option shouldn't affect the QT Player playback.
I hope this clarifies the point.

Pixel Aspect Ratio Issues-FCP HELPP!!!

Okay folks, so currently I am putting together my reel in FCP, however I am encountering a few issues. So my source formats are different in pixel aspect ratio, some was shot on the 7D, some on the Alexa, and some on super 16mm, and a few after effects animations. However all of it is HD, and in ProresHQ 422. My problem here is when I import all of my media into FCP if the timeline is set to square pixels, the HD(1440x1080) footage looks squished, and if I set the timeline to HD(1440x1080) the square pixel footage looks blocky, pixelated and super square.
That said, some of the footage from the 7D is labelled as square and some is labelled as HD(1440x1080), and all the after effects stuff is square.
Right now i am dealing with it and just leaving my timeline as green-preview render, so everything looks mostly normal. However whichever format is not that of the timeline, the footage is degraded a tiny bit, so that when I pause the footage it looks great, but in preview it is slightly blurry.
My question is, is there a way to format everything as either square or HD(1440x1080), so it looks normal, or is there a way to use mixed media formats and not have the preview blur. I'm going crazy over here, as I just graduated and am in dire need of a reel so I can begin to apply for jobs, etc....Or is there a way to formate my prores setting to transform everything to square pixels?
Thanks guys!

You can use compressor to convert everything to square pixels, however there's no need to worry about how it looks in fcp when it's playing but not fully rendered. Try exporting a short section (mark an in and out around the section - and going file: export: quicktime Not quicktime conversion) with current settings. If you render the material, it should look fine when you play it within fcp. Unfortunately, the render settings in the sequence menu are not particularly intuitive, but do a little playing around with them if you've got the time.
I prefer to convert all my sources to my intended pixel dimensions, frame rate and codec before I edit in fcp, but it may not be necessary in your case.

Pixel Aspect Ratio bug in Media Encoder export

Having a weird bug in media encoder exports that I can't seem to figure out. I have a 1080p sequence with a mix of 1080p footage and PAL DV assets. The PAL assets have a pixel aspect ratio of 1.0940. When I format them in my Premiere sequence, I am able to scale them correctly and they look fine. When I export them directly from premiere to broadcast standards it's also fine.
However, when I try to export these sequences in Media Encoder via File->Export->Media-> Queue using the same exact settings (I'm using a preset), Media Encoder formats the PAL assets as if they have square pixels. Thus, half of the footage in my sequences gets horizontally "squished." Note that this does not happen for footage that natively has square pixels, such as my 1080p camera footage.
Has anyone encountered this bug? It seems strange to me that Media Encoder would treat items in a sequence differently that Premiere during export, I was under the impression they were using the same rendering engine... It's really a problem as I'm going to have to crank out multiple versions of this 48-minute film and not being able to queue those exports is going to be a huge headache.
Using latest version of CC 2014.1 (8.1.0).

A Little question about Pixel Aspect Ratio

This doubt has been bugging me since I started edit HD formats.It's about pixel aspect ratio.
Let's supose I have received some material in HD format,for instance.But I will deliver this material in another format, DV NTSC,for instance.
The Pixel aspect ratio format of the material what I received and the way how I will deliver are different.What can I do to avoid this problem? Do I need to apply some plugin to solve this problem or when I export the final sequence Final Cut does this automatically?
thank you

The software takes care of it for you.
As long as your conversion maintains the overall aspect ratio (ie 16:9), it is irrelevant what the individual pixels are doing.
For example, if I convert DVCProHD 720p to ProRes 720p, it will look fine even though the DVCProHD started out with 960 pixels in the x dimension and the ProRes will have 1280.

Changing pixel aspect ratio during cropping (LR3.2)

When I crop sometimes the pixel aspect ratio changes here. I.e. the pic get stretched in horizontal or vertical way/or compressed. Any body seeing this also? After some time it does change to normal, but it makes cropping rather difficult when in a hurry.

I'm not sure I understand your problem, but I think what bothers you is the technique that has been in place in LR2 already for switching between landscape and potrait format of the crop, which in LR3 can be acomplished by the X keyboard shortcut.
Moving your mouse horizontally or vertically on a locked aspect ratio, the format will change from portrait to landscape or vice versa. To enlarge or diminish the size of the crop, you have to move the mouse diagonally.

Anamorphic Pixel Aspect Ratio

I am confused on all the different ways to get the "cinematic look". There are various ways to do this and I want minimal distortion. I have PE 10, source Canon T3i in camera settings are 1920 by 1080 23.976fps. Initial project settings are DSLR>1920 by1080>24fps, square pixel ratio 1.0.
My first question
1- Is shoting anamorphic in itself a distortion of the actual scene?
2- If it is distortion of the actual scene, then it seems like strching the image in post or with a lens shouldn't matter to much?
3-I can right click>Interpret Footage and then select conform to --"D1/DV NTSC Widescreen 16:9 (1.2121)" or "Anamorphic 2:1 (2.0)" or "HD Anamorphic 1080 (1.333)". Which option would be best to get a proper depiction of your scene but also while achieving the "cinematic look"?(if any at all). (to me...it seems like "D1/DV NTSC Widescreen 16:9 (1.2121)" does the best)
-buying anamorphic lens with an adapter that screws onto one of your prime lenses is the best option but it is a pain to have to deal with and is very expensive.
The easiest option is to select a title and put two black rectangles over your footage to mask it. I don't want to do this because you lose some of your footage and I would like to preserver all the footage if possible.
Thanks

I could be mistaken..I'm not even sure
Premiere says it will "Conform" the "Pixel Aspect Ratio". When I select "D1/DV NTSC Widescreen 16:9 (1.2121)" the pixel aspect ratio is changed from its original 1.0 square pixel to 1.2121. This is a screen shot of what I have been encountering. When this happens you do not lose any of the original footage by covering some of it up via a title and you get the "cinematic look" the wide screen look. So Yes, I am trying to get the 2.35:1 movie frame that you mentioned. That’s what I'm ultimately aiming to get. (the clip as you see it has yet to be changed, have not applied it yet so no black bars.
This is what it looks like with the "D1/DV NTSC Widescreen 16:9 (1.2121)" conversion applied.

Pixel Aspect?

Hi there,
I'm trying to learn about using FCP and Livetype. I'm reading a book which tells me to edit my project properties to ensure a .90 pixel aspect ratio as per standard DV. However, I don't see this anywhere in the file information in FCP. Does anyone have a good way to calculate the pixel aspect for my video. I shoot mostly in HDV now, but I'm thinking of getting a more advanced camera and would like to be able to get the pixel aspect information on my own if possible.
I would choose from the information offered in the browser of FCP, but the "Compressor" column lists "DV/DVCPRO" while the "Pixel Aspect" column lists "NTSC - CCIR 601" so I can't really see why the book suggested I use the NTSC-DV 3:2 preset instead of NTSC -CCIR 601. Ok, I'm just generally pretty confused!
Any help would be appreciated!
Lawrence

And I guess that I would use the "Compressor" column of the browser describing my media in my FCP project to assess the preset needed for Livetype?
For the most part, yes, use the Compressor value in your FCP sequence to select the appropriate preset in LiveType. (Though when working with SD - aka Uncompressed 8-Bit or 10-bit - this won't work.)
There are times, however, when you have to adjust those presets in LiveType. If you are working on an Anamorphic SD/DV project, you'd need to alter the Pixel Aspect to 1.2 after you've selected the appropriate preset. I'm sure there are other circumstances as well, but that's the one that always sticks out in my mind...
