Aspect Ratio of Letterboxed DVX100 Footage

I'm wondering if anyone knows what the exact aspect ratio would be of DVX100 footage with the widescreen matte turned on. In trying to measure it in Final Cut, applying the 1.66:1 and 1.70:1 mattes don't do anything, but the 1.78:1 matte crops off a slight additional amount of any shot. Using Compressor, the 1.75:1 matte also crops off slightly more footage than was originally matted by the letterbox.
If it helps, here are the numbers that Compressor provides:
Using 1.66:1 matte crops the top and bottom to a value of 47. Using a 1.75:1 matte crops the top and bottom to 57 and selecting 'Letterbox Area of Source' crops the top and bottom to 54.

I can't tell you exactly what aspect ratio the DVX100 with the widescreen matte turned on. I can tell you what a 4x3 matted aspect ratio should be. It should be 4x3 1.77777778.
Figuring this out in NTSC broadcasting specs is a little misleading Eg: 4x3 1.33 native equates to 720*486=1.48148148148 or 720*480=1.5 due to non-square pixels. Conversion to square pixels helps. 640*480=1.33333333. for 16x9 640*360=1.77777778.
I wouldn't rely on a correct line count coming out of the camera or out of Final Cut without a profressional grade scope ie: Tektronix.
So, if what you're trying to do if place mattes to match your video I would suggest creating the mattes manually to line up with the existing mattes.

Aspect ratio problem with original footage.

I use a Canon mini DV camera (MD160) that shoots in widescreen, and I do all my editing in iMovie 08, all projects are Widescreen 16:9.
No problems until now, but I imported footage the other day that came up squashed (pillarboxed) in 4:3 size. The thumbnails are normal size (widescreen), as they always have been, but the preview screen has cropped the footage to make it fit in my widescreen project. So I'm losing some of my shot.
What really messes me up is that this has happened to random pieces of footage from 6 months ago too, but some footage from last week is unaffected. It is NOT THE PROJECT that has changed, but the original imported footage in my event library, which was always widescreen. Even original shots I took with the iSight camera have changed to the squashed format.
And I obviously can't e-mail Apple, so what's going on? Is there any idea out there what caused this? And how do I alter original footage - I don't want to crop, so is there any way to stretch a 4:3 image into 16:9 - if I can, it will look fine, back to normal.

<font color="blue"The thumbnails are normal size (widescreen), as they always have been, but the preview screen has cropped the footage to make it fit in my widescreen project. So I'm losing some of my shot.</font>
The thumbnails use the current embedded "scaled" dimensions to create the aspect for the thumbnails. On the other hand, the project ignores the current dimensions and uses the embedded aspect flag to set preview display and export/share output.
If you then "move rejected clips to trash", it deletes the bits you don't want, but then converts the remaining section into a "mov" file. This is what has been happening to my footage. So basically I can't get rid of extraneous footage (60GB+ of the stuff!) without altering the aspect ratio of my movie. How do I stop this happening?
Thanks for posting this information. It seems that when the "kept" file segments are copied to the new file container, the aspect flag is not copied. Believe this should be brought to Apple's attention ASAP as an enhancement (or a bug since it does not adhere to aspect flag priority use in main routines). Will run my own test to confirm this and likely post my own feedback report. Suggest anyone else having this problem add their support to get this corrected as soon as possible.

Change aspect ratio to letterboxed

Hello.
I have a whole sequence in image size 640x480 that is pillarboxed. I want to turn this into a widescreen sequence as i think it's a 16:9 letterboxed. any ideas on how i can do this? I am new to the behind the scenes of premiere pro.
thanks in advance

I don't understand what it is you really want.
Your footage is 4:3 using square pixels. (Or is it really something else?) To make it 16:9 widescreen, you would have to chop some off of the top and bottom. Let's say, you would end up with 640X360.
OK. now you have lost some from the top and some from the bottom and you have a widescreen video. But it is pretty small. Is that what you want? Or did you think you could blow it up to HD?

Matching photoshop aspect ratio to HD footage

I am currently working with some HD footage from a Canon HG10. I wan't to incorporate my own photoshop files, but I have no idea how to match the aspect ratio to my HD footage.
The sequence settings in PP are:
HD anamorphic 1080 (1.333), Frame size 1440x1080

I'm not so sure the camera shoots video at 1920x1080 - it will record stills at that size. But in a review I had read :
"Canon is also claiming the HG10 is Full HD, which has become a rather confusing label these days. Canon appears to be using it because the CMOS sensor records HD video natively at 1,920 x 1,080. But the recording format itself is still 1,440 x 1,080, even in HXP mode.
Read more at http://www.trustedreviews.com/Canon-HG10-HDD-Camcorder_Camcorder_review#hi3oKd2ZuvlykubZ.9 9"
I have never used this camera, but the manual says nothing about recording video at 1920x1080.
Maybe others more familiar with the camera can chime in.

Display Modes and Aspect Ratio

I have a project that contains 4:3 and 16:9 footage. It is being prepared for 4:3 VHS release as well as 16:9 DVD release. For the DVD, I have exported all footage out of FCP from a 16:9 timeline. The VHS master is being sent to get captioned and the subtitle files for the DVD will be generated from this same master.
I originally thought I could just drop the video in its entirety onto two tracks in DVDSP, set the display mode of track 1 as 16:9 letterbox and the display mode of track 2 as 16:9 pan-scan. Then I could use chapter markers and stories to navigate as needed depending upon the aspect ratio of the original footage. The problem is this doubles the size of my DVD. I didn't think using the same footage on two tracks should increase the size as it is simply referencing the same file, but alas it does.
So, if instead I put only the true 16:9 footage on track 1 and only the pillarboxed (originally 4:3) footage on track 2, this solves the DVD size problem but screws up my subtitle timings, which I can certainly shift as needed but there are a LOT of small pieces in this project and it jumps between aspect ratios a lot so it will necessitate a lot of subtitle shifting.
Is there another better way to approach this? Hope my description was clear enough.
Thanks in advance.
P.S. Public thanks again to hanumang, whose responses to a previous related thread helped get me this far...

Hi Steve, thanks for your reply. I did not explain well. I am not planning to put both 16:9 and 4:3 versions on the DVD. What I am doing is using only 16:9 encoded video on the DVD. This is achieved by placing all footage (16:9 and 4:3) on a 16:9 timeline in FCP and encodeing to widescreen using Compressor. When I do this, the footage originally shot in 16:9 comes through unaltered while the footage originally shot in 4:3 comes through with pillarboxing.
Ultimately, I need widescreen footage to appear unaltered on 16:9 monitors and letterboxed on 4:3 monitors and I need the footage that was originally shot in 4:3 to appear pillarboxed on 16:9 monitors but unaltered on 4:3 monitors.
Based on the way I am exporting my footage from FCP, if I use a single track in DVDSP and place all the footage on that track and set it to 16:9 letterbox, I believe the footage that was originally shot in 4:3 will get postage-stamped, since the pillarboxing was created by FCP when 4:3 footage was placed in the 16:9 timeline.
The way I have been ensuring things appear correctly is to place ONLY the footage shot in 16:9 on one tack in DVDSP (set to letterbox) and ONLY the footage shot in 4:3 on a second track in DVDSP (set to pan-scan). They have to be on different tracks to allow for different displlay modes but that is necessary to insure things appear properly on all viewing possibilities.
Perhaps there is another way to set things up in FCP and export differently? Please let me know if you see another solution.
Thanks much!

Please watch and see if you can tell me how to correct the aspect ratio

This is an unfinished std. def video hence this issue I ran into which is just a fun video for my youth group kids I teach at my church. I am editing it in final cut pro 7 and if you see at about 35 seconds the aspect ratio changes whatever its doing with the picture there.
I have never ran into this problem before so I don't know if its something I may have selected on the camera accidentally or done wrong in FCP but I shot all the video the same day of course for this event of ours and all the other video is fine an in 16:9 or what was called the "letterbox" option on my Panasonic DVX100B.
Please help me correct it if you know how. Thank you very much in advance.

I can't watch the video as well. Not quite sure what trouble your having
Aspect ratios can be tricky and there are a few spots you can mess them up. First I would check to make sure that your sequence settings are the same aspect ratio as your original footage. I would also make sure your exporting with the correct aspect ratio as well. (If you’re using the quicktime conversion option. Sometimes depending on your settings options like 16:9 are not turned on by default and you need to check them before exporting.)
Also if you can change the aspect ratio in FCP regardless of your sequence's aspect ratio is. Under your distort tab there is a aspect ratio option. +33 will make your footage 4:3 and -33 will make your footage anamorphic. However this will only stretch your footage. This method is only useful for when you can to place 4:3 footage into a 16:9 sequence without it appearing distorted and stretched

Aspect Ratio Issues in Timeline

This may be a simple fix, may not be. I've searched the discussions, and have come close to an answer, but each topis is just slightly different than my specific issue.
Details:
Shot in 16:9 on Canon XL2.
Imported media just fine, clips looked fine in FCP, etc.
Imported archival historical photos and film footage just fine, put them in timeline and resized each individually. They also looked fine in the 16:9 sequence.
Created a new sequence where I tried a different cut on a later section of the timline. (I just copy and pasted the material from the original timeline into the new sequence. This may be where I went wrong.)
I liked what I had and so replaced the end of the timeline in the original sequence witht the newly edited section from the second sequence. (Same copy and paste method.)
Problem:
All of the aspect ratios for the original footage (16:9) and the b-roll (4:3) material was off (stretched, etc.)
I figured out how to change the origianl shot footage to its correct 16:9 aspect ratio, but all of the b-roll still is'nt correct--it's streched virtically, covering the bars at the top and the bottom of the canvas window. (The bars are black by the way, if this is an indication of settings.)
How can I get all of my b-roll back to fit the 16:9 aspect ratio of the project?

I was able to fix my issue...sort of.
I created a new 16:9 sequence and then pasted a copy of the original timeline into it. Because it was a true 16:9 sequence, all of the b-roll (still photos) were "squished" back into a 16:9 frame, hence making them look correct (because they had been stretched vertically over the 16:9). I knew the original 16:9 clip would also be "squished", but I knew I could manipulate the size of these clips much easier (they were all the same size, unlike the b-roll, there was no motion, etc.).
So, I took one of these clips and manually resized it's aspect ratio to fit the 16:9 exactly. Then I copied the clip, selected all of the rest of the clips that needed to be resized and pasted the size attributes. Viola!
Now my only concern is making sure when I export a QuickTime, and when I show it on a 4:3 TV, it will look correct, meaning it will not be stretched vertically to fit the screen, but instead will remain 16:9, with black bars on the top and bottom of the screen.

Cannot get 16 X 9 aspect ratio on NTSC monitor

Just installed a Radeon 9800 pro Mac edition to replace the original GeForce 5200 that came with the computer. The new card is great and gives 30 fps on the main LaCie electron blue 19" monitor when "Full screen" mode is selected. Problem is ... when I select "External video" regardless of the option selected under "Preferences" in "Output" the framerate drops to 6 or 7 fps. The image on the Sony PVM monitor always shows in a stretched 4 X 3 aspect ratio with letterboxing all around it, top, bottom and sides regardless of what option I select in the ATI preferences on the Mac2TV panel. Now when I drag the viewing window from the main monitor to the External Sony PVM monitor and select "Full screen",(external video turned off) the aspect ratio remains in 16 X 9 with an acceptable frame rate.
Any suggestions out there? Thanks!

A solution for "Video output"
When sending an FCP 5.1.1 HDV sequence to "Motion project", it sends it at 1440 x 1080 and Motion 2.1.1 will open a new project to that size. Once that FCP HDV sequence is opened in Motion 2.1.1 and "Full screen mode" is selected it will play to a full screen in 16 x 9 at 30 fps on the "Main Computer Monitor". In this case the main monitor is a LaCie Electron blue 19". Now if "External video" is selected that being a Sony PVM 1351Q the image will show as a 1440 x 1080 and play at only 5 fps. Furthermore it will create a letterbox on all four sides. (looks like a stretched vertical 4 x 3). Now if a new project is opened in Motion 2.1.1 in HD (1920 x1080) and the same HDV QT file is imported in Motion ; the same procedure repeated, the image will play at a proper size and the 16 x 9 aspect ratio on the secondary NTSC Monitor will be respected, mind you it will still play at only 5 fps.
"SOLUTION"
By canceling the "Video output" on Motion, a full frame 16 x 9 image can be viewed on the "Main Monitor". By the way, that image is astonishing compared to what it was with the previous video card. Now by dragging the "Viewer image" above the timeline to the "Secondary Monitor (Sony)" and selecting the "Full Screen Mode" it will then give a proper full screen image with a 16 x 9 aspect ratio on the Sony PVM 1351Q at 30 fps. The image seen on the NTSC monitors when using FCP 5.1.1 in HDV has also improved to a great degree. It has improved to the point where the Radeon® 9800 Pro Mac® Edition 256MB AGP becomes an interesting solution for HDV editing in Final Cut Studio.
If somene has a better solution, I'm all ears! ... or all read!

Output aspect ratio

I'm trying to maintain a 16:9 aspect ratio and its driving me nuts! I have a short project in FCP. Sequence is set to 720x480 anamorphic 16:9.
Im trying to export for web. Ive tried compressor and QT conversion.
Ive set the output size to 640x360
Ive checked the box, "preserve aspect ratio using letterbox"
at first I got lines on the top and the bottom but the picture was still too tall and skinny.
after changing the size to 640x360 anamorphic, now I get black lines on the sides but the picture is STILL too tall and skinny.
any suggestions?

Go back to the original file that you exported out of Final Cut Pro.
Open the file in QuickTime Player.
Press the command and J keys to open the Properties window.
Click the Presentation tab and activate the checkbox next to *Conform aperture to:*
The setting will jump from Classic to Clean and the video will be displayed in a 16:9 aspect ratio.
Press command and S to re-save the file with this setting.
This file will now be the basis for exporting a file for the web, which can be done right in QuickTime Player by opening the *File > Export for Web* item in the menu bar.

FCP project not the correct aspect ratio when exporting to Quicktime

Hello All;
I am trying to export a FCP project in its native resolution (1440 X 1080) to Quicktime but everytime I try, the aspect ratio is messed up and people look taller and thinner than they should.
The project is a resolution of 1440 X 1080 as determined by examining the sequence settings in FCP.
I configure quicktime (see below) to a resolution of 1440 X 1080.
So why isn't my Quicktime video the correct resolution when I play it with the IMac's Quicktime player ? I shrink the player to 1/2 size to fit it all on the screen.
My exact settings are below ...
Export - Using Quicktime Conversion
Format - Quicktime Movie
Video Settings - Compressor - MPEG-4
Quality - Best
Not sure if I changed the framerate - if I did, I probably changed it to 29.97
I didn't touch the other settings in the video settings - left them to default
I didn't change the filter settings - I left them at default
Size - 1440 X 1080 (The actual resolution of my source video)
I checked the box - preserve aspect ratio using letterbox (If applicable)
Other settings were left at default
Sound Settings - Format - AAC
Rate - 48 KHZ
Render Settings - Quality - Best
Target Bitrate - 128 KHZ (This was left at default - I did not change it)
Prepare for Internet Streaming - Fast Start checked (This was default - I did not change it)
All other settings not specifically mentioned were left at default.
Thanks. Tim

I don't have much of an answer for you, but to test try not checking the preserve aspect ratio. Rather than reexport the entire 1 hour just export 10 seconds so that you can trouble shoot different things.
Hope that helps a bit,
Eric

Aspect Ratio of Compostion

Question fellows,
Should you create the composition in the aspect ratio, it is gonna be used for , or leave it at the default settings. Becaused am not sure??
Thanks!!!

Todd provided a good link to explain things, but there really aren't any hard and fast rules. It depends on what you're expected to deliver. You may have HD footage, but you need to deliver an SD file, for example.
Here's another example: I work a lot with DVCPro HD footage shot at 720p 60. It has a wide pixel aspect ratio of 1.33 and a resolution of 960x720, not 1280x720. You'd think I'd work in a DVCPro HD comp preset using that pixel aspect ratio and resolution, right?
Nope.
I work in a 1280x720, square-pixel comp. AE knows how to interpret the footage, so it looks just right in the comp. Furthermore, because it's a square-pixel comp, circles remain circular and squares remain square. Text looks nice 'n smooth all the time. Life is good. I can also render back to DVCPro HD from this comp. That's because the codec defaults to rendering 960x720, with the same pixel aspect ratio as the original footage.
So it all depends.

FCP export aspect ratio issue

Hi everyone!
I would like to export HD footage with FCP using quicktime conversion. My original footage is 1920 x 1080 and I would like to to convert to 640 x 272. When I export I enter the desired size and tick "preserve aspect ratio". However the footage gets distorted. Can anyone help? Thanks, Jo

What happens if you open the clip in QT player, then go into the movie properties window (cmd-J) then under the presentation tab change the aperture display mode to "production"?
About QuickTime Aperture Display Modes
QuickTime 7.1 and later supports four aperture display modes that allow you to properly display video with nonsquare pixels (such as DV video) in QuickTime Player and other applications that support these modes. The four aperture display modes in QuickTime are:
- Classic
- Clean
- Production
- Encoded Pixels
To change the aperture display mode of a QuickTime movie:
1 Make sure a QuickTime Pro registration code is entered in the Register tab of the QuickTime pane in System Preferences.
2 Open a QuickTime movie in QuickTime Player.
3 Choose Window > Show Movie Properties.
4 In the Properties window, select the main movie track (not the video or sound tracks).
5 Click Presentation, then choose an aperture mode from the “Conform aperture to” pop-up menu.

How can I edit DVCPROHD in FCPX? Need to Adjust Aspect Ratio

I have 5TB of footage for a sitcom I'm about to start editing. It's all been ingested and organized in FCPX event browser. However, it appears the FCPX won't allow the change of aspect ratio for the 1280x1080 footage. The DVCPROHD footage appears squished. I need to make MultiCams out of all the scenes shot film style and need to be able to view it at a correct aspect ratio not only in the timeline, but in the Event browser playback as well - so I can make informed decisions on which takes to use in the edit. I've seen recommendations for people creating "custom resolution" timesline by ingesting a pre-made video clip that's been customized in motion, but that wont' fix my problem. There has to be a way to natively edit DVCPROHD footage. Can some please help with suggestions??

Not by using the IMAQ WindTools directly. One idea is to draw a rectangled ROI first (using ), then modify it programmatically using the IMAQ ROI functions ...

Interpretation rules not working; can't change pixel aspect ratio

Hi,
I'm following the instructions on the Adobe help site here...
http://helpx.adobe.com/premiere-pro/using/aspect-ratios.html
...so that I may use custom pixel aspect ratios in the interpret footage dialog box.
Unfortunately none of my changes to this file have any effect, and I'm clueless. These are cinemaDNG sequences and I'd like to keep working with them raw, otherwise I would take the time to export them and stretch them en masse through AE.

Hi Kevin, a mix of BMPCC and 5Dmk3 Magic Lantern. ML raw at 60p has a non-standard PAR, most of my footage is shot in this format. I need 0.65, the closest is 0.9091. I was disappointed at first to find no ability to manually enter the value, then elated to find the Interpretation rules text file, then disappointed again to find it doesn't work...hoping this ends well!

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!
