Video support: resolution, portrait mode and aspect ratio
I have been playing with a friend's PowerPC-based mini (while I wait for Leopard to come out) and have some pre-purchase questions:
1) Do the current Core 2 Duo mac mini models support the VESA standard Preset Timing Mode of 1680 x 1050? (That's not listed on his older mac mini and would affect my choice of monitor.)
2) Does the current mac mini support portrait mode with any monitor at all?
3) The specs list maximum resolutions of 1920 x 1200 (16:10) with DVI and 1920 x 1080 (16:9) with VGA. I'm guessing that is related to bandwidth of the cable and does not mean that all output to DVI would be at the 16:10 aspect ratio and all output to VGA would be at the 16:9.
mexibeetle,
As far as the resolution of 1680x1050 I cannot answer you. I have a Power PC mini as well as an intel mini. The resolutions available change based on the display connected, but neither of mine offer that particular resolution (the 17" monitor I have does not go that high on the PPC mini via VGA and the intel mini is hooked up to a 40" LCD TV via HDMI...those resolutions are either 1600x900 or 1920x1080)
Neither my monitor nor my HDTV list that particular resolution (1680x1050) as being available, regardless of what they are connected to, so I cannot say whether or not the mini is capable of driving a screen at that resolution.
As to portrait mode, on both the older and newer minis in the display preference pane there is the option to rotate your image...90, 180 and 270 degrees. Mounting your monitor horizontal or vertical should not pose any problem as far as I can see.

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! -
Could somebody please help me with my problem?
I am creating a slideshow, using iMovie '08, for a party I will be attending. I am going to make copies for several guests but I am lost on the details. The master copy of my project is 1920x1080 HD. So, in what resolution and aspect ratio should I make my guest copies given that each guest will have a different television and aspect ratio setting?Send the file to iDVD and create standard definition DVD's.

While Windows.Current.Bounds returns the application windows size, in order to create a full-screen bitmap my app would need to retrieve the full display area of the device. I cannot even get the aspect ratio.
Pre-Win10, using Windows.Current.Bounds I can create a bitmap of whatever size application window the user is seeing. When the user is showing my app at full screen, I can therefore get the full display area and aspect ratio of the device and create a full-screen
bitmap.
With Win10, the user would need to know to hide the taskbar and also display at full-screen before an app can retrieve the display area and aspect ratio using Windows.Current.Bounds.
Before Win10 it's obvious to the user that full-screen is or is not being used. When I create the bitmap, I create it to fit the application window. When the app is displayed full screen, the bitmap will be full screen. Also, the app starts full-screen so
I can detect the display area at startup if I need to.
With Win10, to the user the app "looks like" it is full screen with the taskbar displayed even though it's not really full screen.
I believe that in Win10 determining the full display area will be useful and not just retrieving the application window size.
musical9Rob, Is this forum best way to get my suggestion to the development team?

My Ipad display is stuck on portrait mode. I tried the toggle switch, turning off and restart and just now backed up into Itunes and restored and still is stuck on portrait mode and it won't flip to landscape mode. Is this a hardware problem?
Has lock rotation been accidentally enabled within the control centre? If you swipe up the screen is there a circle with a lock symbol & if so is is greyed out or white - if white it is enabled.

Quality and aspect ratio with FCE and iPhoto
Project started by importing hundreds of slides shot by different cameras with difference settings. Slides were imported into i-photo where I used the slideshow function to make several segments. As I was choosing the photos and dragging them into slideshows I cropped them all into 16x9 ratio so they would all be uniform. I then sent to QuickTime movie using the built in iPhoto export button and selected “custom export” setting with DV/DVCPRO-NTSC compression with quality set to “Best” and aspect ratio to 16x9.
Then imported into FCE and did serious editing (music, effects, titles, etc.). When finished I tried exporting as both a QT self-contained movie and QT conversion (using DV/DVCPRO and 16:9) but the quality is terrible and when I make a iDVD the picture is squeezed and distorted into a 4:3 ratio despite the fact that the IDVD is set to 16:9. I have spent over a month on this project and have fellow travelers waiting for my “creative” touch. Can anyone tell me where I went wrong on both aspect ratio and quality? Thanks.
PS: Am using MacBook Pro, OS 10.7.4 FCE 4.0.1 and iPhoto-11 9.3.2Hi
I'm not shure - but I can share my thoughts
I tried exporting as both a QT self-contained movie and QT conversion (using DV/DVCPRO and 16:9)
I DO NEVER - Use Export as QuickTime CONVERSION
I DO - Share as QuickTime .mov - straight off
I had problems with 16x9 until I understood that
• I had to select type of project as WideScreen in FC
• Browser Window in FinalCut E and Pro - can extend far to the Right with several Columns. One Column states Anamorphic. When set my material to this. THEN introduced it into TimeLine. Can not be done in after hand.
• Export as above
• In iDVD there are TWO places to set 16x9
- When creating a NEW iDVD Project - SELECT --> WideSrceen
- In iDVD Project / Projectinfo [ Shift+cmd+I ]- ALSO set 16x9

After watch a video in "full screen mode" and the video shrinks back into the eBook view, HALF of the TOP Title Bar DISAPPEARS, But it does not happen with ios 6.1
The Mac has never needed "Full Screen". It has done multiple screen Extended Desktop since 1987.
Full screen is an iPhone feature, carried into this verion with the mult-touch gestures and other so-called "unifying" features. -

Hi,
I'm think of getting the Apple Video adaptor for use with my Sony Widescreen TV. As I understand it, this adaptor outputs an S-video signal that mirrors the iMac's built-in display.
Will this display in true widescreen on my TV or will it be in a 4:3 aspect ratio? Is there a way of choosing between the two?
Any help would be appreciated.
ThanksThanks for the reply. I don't think my question was a clear as it could've been.
What I really want to know is: will my iMac output s-Video that is anamorphic widescreen. i.e. will I be able to fill my TV's screen without "stretching" a 4:3 image?
Or, is the iMac's s-Video out limited to Standard PAL or NTSC 4:3 without support for anamorphic enhancement?
I know that the iMac supports 4:3 and 16:10, but widescreen TVs are 16:9.
Thanks for your help. -
How to find the size and resolution option in the aspect ratio drop down menu for the crop tool
while looking through certain tutorials on the new crop system i came across many that referenced the above mentioned size and resolution option in the access ratio drop down menu. They all mention a dialog box which then appears which looks really useful, however my version doesnt have this option. any help would be appreciated.

Yes, definitely already differences. I sympathize with Photoshop instructors (online and offline).
The headline change was Retina support but that was also made available to non-Cloud versions.

Display resolutions and aspect ratio's
Two questions:
1. Is there a way to get the aspect ratio of the screen?
2. Is there a way from within Java to take over the entire screen and set the screen resolution without using DirectX?hi!
for your first problem you can reffer to Toolkit.getDefaultToolkit().getScreenSize() after that you can easily calculate the ratio..

Preparing photos for iPhone 4 - resolution and aspect ratio
Is there an optimum photo size when preparing photos for display on the iPhone 4 or does the iPhone optimize the size automatically upon import? Also, what is the recommended aspect ratio?
Dan, I did a quick check with one of my pictures. Normally I prepaired my photos in Photoshop to a size 1920px : 1280px with embedded Color Profile (sRGB) for iPhone 4. Then I save it in a folder. With iPhoto I import to a album then sync with iTunes. Now for a test, i sent one photo from the iPhone via email to me, opened in Photoshop to see any difference to the original photo on my computer. It´s the same size and same quality. Only the color profile is not embedded. Maybe iPhoto-iTunes does a small color correction for the iPhone display.

Render Previews Size and Aspect Ratio
We are currently editing several projects that have an odd editing dimension but a standard output dimension. These videos are for a live event with rows of four projection screens set somewhat tightly together. From a production standpoint, we wanted to have content flow freely across all four screens. We prefer not to have to visualize this, so we set up a "Desktop" mode, square pixel sequence within a project with a dimension of 2560 x 540. The 2560 dimension is because most of the footage is from the Panasonic P2 camera (HVX200P). This camera shoots video at a rectangular pixel dimension of 1280 x 1080. The pixel aspect ratio is 1.5. So 1.5 times 1280 = 1920, the final output square pixel dimension. In this case the final output WOULD be 1920 x 2 or 3840 x 540 high. 3840 divided by 4 = 960 x 540. So we're outputting standard def widescreen to each screen. Premiere automatically creates the final output through nesting the 2560 x 540 sequence twice in a DVCPROHD 1080i sequence of standard size. The two 2560 x 540 sequences, one on video layer 1 and the other on video layer 2 are positioned so that the video that corresponds to screen one is positioned top-far right and the second instance of the sequence is positioned bottom far left. The final output file is an avi in the Canopus HQ codec at 1920 x 1080. This output file is a video that is actually four standard def videos in one 1920 x 1080 video. The Grass Valley Turbo 2 outputs this standard hi-def file to a Vista Spyder which will isolate and project the four videos-in-one, to the appropriate four screens.
This type of project would not have been possible without CS5 and Mercury. Premiere is handling this oddity extremely well.
One minor issue for the support gurus:
When we render the Desktop mode square pixel 2560 x 540 sequence timeline, we get what appears to be random, mixed render results. Sometimes this odd shape renders perfectly, other times it renders out to small dimension that is less than half size. Other times if renders out with pieces of the elements small. but positioned with spaces between them. Playing around with sequence render settings and playback resolution, sometimes SEEMS to cause the render to correct itself. Sometimes a computer restart SEEMS to correct the issue. Any thoughts?Colin Brougham wrote:
Barring previewing, are you able to export to your intermediate/final movie without problems?
The final exported video is 1920 x 1080. I have test exported in a number of formats without any problems at all.
The 2560 x 540 version, (BEFORE it is "processed" through 2 instances of itself in a standard DVCPROHD sequence) is for editing purposes only, so we can actually see how the video will play across four projection screens.
The remaining issue I'm trying to work out is, how to best get the finished video into the grass valley Turbo 2. The Turbo 2 takes an AVI file transcoded into the Canopus HQ codec natively without having to transcode. The only way to get an avi from Premiere Pro CS5 into the Canopus HQ codec is to first export the finished video as an uncompressed avi from Premiere, import it into either "Edius" or "Procoder 3" and export in the HQ codec. The export from Premiere CS5 + Mercury takes 15 minutes. The export (HQ encoded file) from the trial version of Edius takes around 10 minutes. IMO grass valley should create a plug-in for Premiere CS5 and shouldn't allow the quickest export to be Canopus exclusive. I seriously doubt many Premiere CS5 users will switching to Edius any time soon.
According to grass valley, the Turbo 2 will accept an MPEG-2 Pgm Stream, whatever the heck a Pgm Stream is???. I did a Google search without success. Of course Premiere will export an MPEG-2 file, but how the Pgm Stream relates to this, I have no idea. There are a mind boggling array of settings and the preset seems to export a rather compressed looking video.
My current thinking is to try to convince the boss to buy Procoder 3.
BTW:
the 3840 x 540 version sequence renders fine part of the time and then for whatever reason starts creating a preview that is about 35% of the correct dimension... So back to the original Sequence settings of 2560 x 540 -
Letterboxing and Aspect Ratio problem
I'm authoring a feature film DVD. All menus and movies are 16:9
When I play the Simulator in "16:9" everything is fine.
When I play the Simulator in "4:3 Letterbox" my menus are letterboxed as desired, however every movie is for some reason squished into 4:3.
Any ideas?
The Video Asset box in the Inspector tells me all my movies are 720x480 16:9.
All tracks show in the Track Inspector as display mode 16:9 Letterbox.
All Menus show in the Menu Inspector as Aspect Ratio 16:9
Also of note, one of my tracks is used both as a movie and as a motion menu. Although it's the same track, with the simulator in 4:3 it's correctly letterboxed as a menu, yet squished as a movie!
I exported from a 16:9 Anamorphic project in FCP (as a QTmovie set to Anamorphic NTSC DV) and imported straight into DVD Studio Pro. (I've noticed on these forums most people go through Compressor. I didn't. Would that be the cause of my headache?)
The movies display in my QuickTime Player as 16:9 clips with a size of 853x480The Simulator is very far from accurate. Burn a disc, then pop it into a DVD player.
