Mpeg-2 Frame Size Limitations?

Can I create an Mpeg-2 frame size large then 720 x 480?

You can but why?
In compressor 2.3 you can change the format(encoder tab ->Video Format) from NTSC to one that is HD (720p, 1080i etc...) and that will increase the frame size. But if your source isn't HD it will look like garbage if it even works correctly.

Jpeg 2000 vs mpeg 4 frame size

Does anyone know why a 1024x768 frame size jpeg 2000 file is a different shape "size" then a mpeg 4 file of the same size? the jpeg one is a lot wider and fill up the whole screen where the mpeg 4 does not.
These are both from keynote and going into final cut express.
Any ideas would be great. Im just curious how the same frame size can look different.

No quick/easy way to explain this - as Mr. Wolsky said in his second post, it is the difference in Pixel Aspect Ratio and the way they are displayed differently on a computer and tv screen, and how content which is purposed for one (Keynote for computer display) and DV (video for a TV) uses a different pixel aspect ratio (PAR).

IWeb Video Frame Size Limitation?

I can't seem to be able to place a movie into iWeb that is any larger than 640x360. It seems that when I try to drag something larger than this into the program, then part of the video gets cut off. Is this a limitation of iWeb '08? Is there any way around this? Does anyone know if this gets fixed in iWeb '09?
Thank you.

The default page width in iWeb is only 700 px wide for some reason.
I use a "standard" page width of 980 px because this will fit most screens without the viewer having to scroll horizontally and also translates well to the iPhone.
If you increase the page width to a bit wider than the size of the width you want the movie, then it will stretch.
This is done in the Page inspector Layout menu.
It also helps if you "Show Layout" from the view menu or do Shift - Command - L.
This will show you the edges of your page.

MPEG Streamclip 1.8 error message "can't read frame size"

I receive message "Error: cant read frame size" after importing a QuickTime Movie file into MPEG Streamclip and choosing File-> Export to QuickTime as suggested in another forum to resolve the problem of no sound when importing a still camera QuickTime Movie file like the following into iMovie.
(MPEG Streamclip imports the sound but no video.)

Can I output to my TV with big frame sizes

Hi guys..
I always though I could store a video on the ipod as frame size 720 by 576 and when outputed to the tv, it play at this frame size. When played on my ipod, it downsizes it to fit. Is this right?
Basically I just want my home video dvds, when converted on \to the ipod, to fit the whole screen of my tv in the same quality it is when I insert my home videos into the dvd player, is this possible.

No, you cannot store full-size video on an iPod. It supports 320x240 in H264 and 480x480 in MPEG, or any other resolution whose total pixel count is lower than the above. The iPod's processor simply cannot handle anything bigger and the battery would drain too fast if anything bigger was used.
You can't get the same quality as DVD (as I said in the other post), but it looks pretty good.
If you import your video at the highest bitrate possible and at 320x240 (the iPod's screen resolution), there won't be much (if any) noticeable difference in quality. What you will see, though, is less detail, especially in smaller or distant objects in the video. For example, if you are watching a video that is zooming out from a scene, you will notice that detail disappears sooner than if you watched it on a DVD. Also, if there are immobile, straight lines at an angle in a video (especially a cartoon where the lines are very straight) then you will notice some small steps, which are a result of the video's pixels being stretched to 2x2 pixel squares. Other than that, there aren't many other problems with video quality that I have seen, as long as the bitrate is kept high.
Basically, the iPod is a very mobile video player. Because it's so small and because its processor is limited in power, it cannot handle full-resolution video. It will look good on a TV that is approx 30 inches or smaller, but don't expect anything spectacular on a big-screen TV. If you're using a large TV (bigger than 30 inches) then you should really be using a DVD, not an iPod.
So, if you want to show your friends some home video on an average size TV then the iPod is fine in terms of quality.

H.264 frame size limit?

I'm trying to compress HD 1080/24p footage in Compressor 2.0.1, and the h.264 dialog box limits me to a max frame size of 720. Why no 1080? I can do 1080 MPEG-2. Is there a way around this?
Thanks!
G5 Mac OS X (10.4.6)

Frank:
Wellcome to the forum!
the h.264 dialog box limits me to a max frame size of 720
Are you trying to encode to H.264 for HD DVD or H.264 QuickTime Movie?
Encoding H.264 as Quicktime Movie lets you gice your full custom frame size (go to Geometry icon), 1080 pixel aspect ratio, etc.
Take any of the existing Web Download or Streaming (QT7), make a copy and change the Geometry settings as you want.
Hope it helps!

Frame size and compressor

I had captured a mini DV movie in another program as an .avi file. When I import this file as is into FCE, its properties show in the browser as:
frame size 720 x 480
compressor DV/DVCPRO - NTSC
data rate 3.6 MB/sec
I then used MPEG Streamclip to export this .avi file into a QuickTime file in 3 different ways. The methods, and resultant properties as they show in FCE, are as follows:
Test 1:
Compressor = Apple DV/DVCPRO - NTSC
Frame size = 720 x 480
Data rate = 3.6 MB/sec
Test 2:
Compressor = Apple Intermediate Codec
Frame size = 720 x 480
Data rate = 2.5 MB/sec
Test 3:
Compressor = Apple Intermediate Codec
Frame size = 640 x 480
Data rate = 2.3 MB/sec
Observations and questions:
In the FCE canvas, Test 1 and Test 2 look pretty much identical. Test 3 looks very slightly horizontally stretched compared to the other tests. Or, as everything's relative, Test 1 and Test 2 look very slightly horizontally compressed compared to Test 3. By the way, I placed markers in each test clip at the exact same frame to get a good comparison. Then I jumped marker to marker while looking at the canvas.
QUESTION 1: Is FCE in fact handling these clips differently due to the different frame sizes?
When I play the clips in QuickTime Player (not pro), Test 1 and Test 2, which both have frame size 720 x 480, are horizontally stretched. Test 3, frame size 640 x 480, is normal. The differences between the stretched and the normal are much more pronounced than they appear in the FCE canvas. When I open the ORIGINAL .avi captured clip (720 x 480) in QT Player, it is normal, not stretched like Test 1 and Test 2 which have the same 720 x 480 size.
QUESTION 2: I know this isn't the QT forum, but is this normal behavior in QT Player?
When I open iDVD version 7.0.3 from iLife '09, the only one of the three test clips that appears in the media browser is Test 3.
QUESTION 3: Does anyone know why? I posted this in the iDVD forum; nobody replied.
I then put the three test clips on the timeline in FCE and exported the sequence as a QuickTime movie. When I play it in QT Player, it is (gulp) stretched; ALL of it, not just the Test 1 and Test 2 portions. The finished .mov file DOES appear in the iDVD media browser; when I preview it there, it is STRETCHED.
QUESTION 4: When I export .avi to QT files in MPEG Streamclip, what compressor should I choose for use in FCE?
QUESTION 5: When I export .avi to QT files in MPEG Streamclip, what frame size should I choose for use in FCE?
QUESTION 6: Why are FCE and QT Player handling the differences in frame size in different ways? FCE shows a very slight difference when viewed in the canvas, whereas QT Player shows a drastic stretching when playing the clips.
Thanks for your help.

Apple Intermediate Codec is reserved to transcode HD content (from HDV or AVCHD). Don't use it for Stand def DV-NTSC nor PAL.
QUESTION 2: I know this isn't the QT forum, but is this normal behavior in QT Player?
There is a setting in quicktime player pro under movie properties (command-J) to select the correct aperture option. That's enable the correct aspect ratio when movie is opened with quicktime.

That's because all cool members are here.

QUESTION 4: When I export .avi to QT files in MPEG Streamclip, what compressor should I choose for use in FCE?
DVCPRO50-NTSC for standard definition and Apple Intermediate Codec (1080i60 or 50 or 720p) for HD.
QUESTION 5: When I export .avi to QT files in MPEG Streamclip, what frame size should I choose for use in FCE?
720X480 for SD, 1920X1080 or 1280X720 for HD

MPEG2 frame size areas greyed out :(

I need to take a QuickTime file that was rendered at 864x486 and make an MPEG2 out of it to playback on a PC onto a plasma screen. However, every MPEG2 I create in Compressor changes my frame size to 720x480. The frame size controls are greyed out and will not let me change this. I am not creating a DVD, but I DO need to create an MPEG2. What am I doing wrong?!? I've read different posts on here that say to duplicate the setting so you're not changing the original, and I've done that. Nothing seems to work.

As Silal mentioned, you are probably best off with H.264, the settings in Compressor for MPEG-2 are for DVD and HD DVD sizing.
Make sure you set it for the highest settings and 2-Pass (may take some time) but it really can do an excellant job. Of course the PC needs to meet the specs to play back H.264 properly. As an aside, the 720 x 404 when used is not too bad. I have run component cables from my DVD Player to a 16:9 TV and it looks good. You may want to try a test.

Sequence Settings Frame Size, LIMIT?

I want to export a sequence that's 1080x5760. Essentially 3 1080p screens right next to each other. Every time I enter this custom setting into the frame size of my sequence, I get a 4000 limit for both height and width. Shouldn't FCP be able to handle this size? Is it limited by my GPU?

FCP currently does not support anything over 4K.

Mpeg1 custom frame size

Hello,
I do a lot of videos or video presentations for sales type people to use within powerpoint files. I usually supply clients with WMV files using flip4mac, which works well.
Occasionally I see mpeg1 muxed movies that are more than the default 320x240 frame sizes. My question is 2 part - 1. Is there a quicktime/compressor way to do this? 2. Any thoughts on whether mpeg1 is a superior way to supply movies for things like inserting into powerpoint presentations?
Thanks
Pete

That's pretty much the frame size of a MPEG-1 file, 320x240. There's a MPEG-1 file called Super Video (CD) that uses MPEG-2 compression for the MPEG-1 file. I think the frame size is 480x360. The video quality is still garbage. The reason you still see MPEG-1 files is that the format is still popular in India and Indonesia.
Use h.264 for your presentation. If you use MPEG-1 you'll hate the quality.
Open that MPEG-1 you have in Quicktime and see what the inspector window tells you what the format is.

Is it possible to define the frame size when capture from MiniDV?

I am editing a series of tapes which I did not film and don't have the original camera. I am capturing it using my Canon ZR500. When I capture it the frame size is 720 by 480 (3:2). Is there any possibility that by using a different camera I could be inadvertently changing the frame size? (I can't see where I could but someone in this project thinks the aspect ration should be 4:3 - I can't see anywhere I could be changing it.)

I have just given this a quick browse but I think it just explains how to make slides match the frame size. I used keynote to make the slide - probably not the best but I don't have photoshop. But the principle should be the same?
But using an incorrect slide size shouldn't affect the aspect ratio of the final video should it?
After I create the .mov file from FCE I use MPEG Streamclip to produce an .mp4 version to upload to the internet. If I use Streamclip to view the stream info it still shows a frame size of 720 by 480.
Am I missing something?

I thought FCP X 10.1.1 could handle non-standard frame sizes?

Yesterday I was demonstrating FCP X 10.1.1 to a friend.
As time was limited I imported the nearest piece of video I could find, which happened to be part of an H.264 video tutorial with a frame size of 960 x 600 and a frame rate of 30fps.
I hit the E key to send it to the timeline only to receive the old "not recognised" error message as shown below.
I thought I may have created the project incorrectly but when I repeated with a new project I double-checked that I had selected "Set based on first video clip".
I thought that FCP X 10.1.1 would automatically recognise a non-standard frame size and simply create an appropriate project.
I was too busy doing the demo to investigate at the time but later I discovered that there was no problem creating a 960 x 600 custom project manually.
It's a pity FCPX is not clever enough to do it automatically ............ or can it?

Thanks Tom, you clarified it ....... or at least something clicked in my brain.
I was trying to set "Custom" when I created the new project.
I didn't know, or had forgotten, that in the "error" window I could select "Custom".
All is now well and FCP X 10.1.1 is pretty clever after all!
There is one weird thing I'd like to mention.
When I clicked on "Custom" the 960 x 600 frame dimensions appeared but the frame rate was listed as 23.98p as shown in the screenshot below.
So what's wrong with that?
Well the clip is 30p and I naturally thought I was going to end up with a project with an incorrect frame rate.
Now here's the funny thing ......... when I selected the project and viewed it in the Inspector it was the correct 30p
So why was I given that worrying piece of misinformation.

Compressor mucking up frame sizes? Totally confused. Help!

Here's the situation.
I have some 720x486 (NTSC-CCIR) 16:9 23.976 video (nice, yummy, uncompressed 10-bit) in Final Cut.
I want to compress this for DVD.
But no matter what settings I use, Compressor mucks it up.
If I use the Apple-provided MPEG-2 5.0Mbps 2-pass 16:9 setting, I get a 720x404 file.
If I uncheck 16:9 in the compressor settings, I get a 640x480 file.
Changing the output format to NTSC makes no difference.
I have tried just about every combination of settings available, and cannot get compressor to stop changing the frame size -- and btw, the "frame size" feature is always grayed out.
Any clues as to how I should proceed?
G4 1.44DP

Actually, I did a fair bit of searching, just didn't hit on the right keywords. Such is search.
Thanks for the info. The tip in the thread you mentioned about MPEG StreamClip was a good one, it confirms that the output is actually 720x480.
For QT Player and Final Cut to not properly describe the native format of the files is outrageously stupid. And Final Cut still cant bring in the .m2v file and use it without mucking it to 720x404. Sigh.
Okay, the basic question is answered. Now for a subtle one, oh wizards.
My source video is CCIR-601, 720x486. MPEG-2 for DVDs is 720x480, oh so slightly different.
If I use the Apple preset, it converts the 720x486 to 720x480. The question is, is it clipping the top and bottom 3 lines, or is it scrunching (which will cause a slight vertical resolution loss)?
Changing the preset to crop the top and bottom 3 lines also gives 720x480, which I assume means there's no scrunching (at the cost of a very slight distortion, which nobody will notice). So this is what I'm leaning towards doing, but I'd like to be sure.

Flash Frame Sizes in YouTube

Hello There,
I’m back in video after a decade long absence and I’m completely new to YouTube because I’ve been living on a continent that rarely even has Internet. I’ve got some old footage I need to put on YouTube, but YouTube’s specs are a bit contradictory at times.
Starting from the get go, I have several questions and I hope you can point me in the right direction. It sounds like an FLV file is what I should go for, so I’ll base my questions on that. Don’t hesitate to answer between the lines. And don’t hesitate to tell me to change tracks.
The most clear export I can make from my old Avid editing program is an uncompressed QuickTime movie. I can’t find anything in the YouTube specs about QuickTime moives. They don’t say they’re good. They don’t say they’re bad. Can I convert to an FLV file and upload to YouTube with good results?
When I export non-HD material from my editing program, what frame size do I export?
When I convert to an FLV file, what size do I re-size to? Or does YouTube resize whatever I send to them to the right size?
When I convert to an FLV file, what’s a reasonable bitrate for video? How about audio?
Or do I even need to bother with the above? In one YouTube information sheet, it sounded like I could just upload a plain old MPEG2 file and YouTube would go from there. Correct or not?
What’s the benefit of an alpha channel? It seems like the files get smaller, but I can’t get them to play at all after I’ve ticked alpha.
If anyone needs the information, I’m using Avid Xpress Pro 4.3 and have access to both AVS and TMPG 3 for MPEG conversion. My computer has plenty of horsepower.
And I'm using CS3 from Adobe.
Thanks beforehand for your help.
CS

Hi There,
I'll mark as answered. Seems like we're on the right track.
I'll upload a small video as a test. But I feel a little bit guilty about that, since I'd be taking up YouTube computer space for something that's essentially worthless.
Is there any way to test a video on YouTube before a final submission?
Thanks again for your help.

Changing Frame Size in MPEG2

I'm using compressor to change less than stellar VHS video to MPEG2. I see that compressor has an option for frame size, but its ghosted out for MPEG2, can this be overridden in any manner? MPEG2 can be resized to LoRes MPEG2, with other programs, to 352x240 which is VHS quality and would make the video look generally better on a TV.

MPEG-2 (or MPEG-1) output file frame size can't be altered in Compressor. Sorry.
