1080i vs. 1080i 50hz

Can anyone explain the difference in these two settings to me? Thanks.
Steve

50hz is the frequency of the electrical supply (AC) in Europe, North America is 60hz. Historically, the television's refresh rate has approximately followed the same frequency.

Encoding time 1080i to 1080i aic

Exporting 1080i clips to 1080i (aic) takes time about 4 times of the length of the video (iMac 2.66 GHZ). Is this normal? Since the imported clips already are converted to aic (I think) I would have thought exporting to the same format would be a lot quicker.

With FCE (export to QT) the time is about the same as the length of the video.

P2 1080i/24p and CS3

Started a DVCPRO HD 1080i/24p project. Imported P2 mxf files shot in 1080i/24p. Timeline needs rendering when mxf is placed on timeline.
Why does this happen? Every other native P2 project for DVCPRO HD does not require rendering. ex, 720/60 etc.
CS4 does not behave this way in the trial I downloaded.

I noticed the same issue while running some tests today. I shot 6 x 30 second clips to p2. 1080i 24p, 1080i 24pa, 720p 24p, 702p 24pn, DVCPro 50 480i 24pa, DVCPro 50 480i 24p. I created 3 sequences, one for each of the resolutions.
On the 1080i sequence the 24p requires rendering while the 24pa does not. Same thing for the DVCPro 50, the 24p requires rendering while the 24pa does not. None of the 720 clips required rendering and neither of those were shot in 24p advance.
I am very interested to find out why this is happening.

Is 1080i ok with 1080i 30p?

I shot a project where the wild life was shot with a Sony Z7U in 1080i 30p (a menu setting) and the interviews were shot in 1080i 29.97. I capture my footage with a Kona AJA Lhi card in DVCPRO HD so the clips come in as 1280 x 1080 (1.5) It appears when I mix the two on a segment set for 1080i the 1080i 30p looks choppy. Any suggestions on a sequence selection to accommodate both?
Thanks

hi, dvcpro hd is a panasonic format,this could be the issue. in premier a hdv 1080i 30 preset should be fine for both video footage.

Working with 1080i 24pA in FCP 6

I'm having problems working with footage shot in 1080i 24pA on the P2 format on an HVX-200 camera. I am using Final Cut Pro 6.0. I have the necessary P2 drivers from Panasonic to access the footage. There is no option in the project settings for 1080i 24pA. The only option for 24pA and the frame rate of 23.987 is 1080p 24pA.
In another forum it said that 24pA stores the 24p into a 60i signal. It suggested to conform the footage to make the 24p-in-60i into pure 24p using Cinema Tools. However, I am unable to access the original clips in Cinema Tools.
Playing the imported clip in the viewer it looks fine. But, playing the clip in the sequence the frame rate is changed to 29.
I did not do a thorough search of the Apple forums because I did not know the exact nature of my problem.

Yes, 1080p not 1080i. 1080i 24pA is what we shot in. There was no option to shoot in 1080p 24pA on the camera, the only option for shooting in progressive was in 720. I don't see any option anywhere in Final Cut Pro 6.0 for 1080 i 24pA.
I was previously instructed to go through Cinema Tools. But as of yet I am unable to accomplish this with the footage.
The footage was injested to my macbook pro using the P2 contents management software provided by Panasonic on their website. I used a DualAdapter brand card reader to read the P2 card and ingest to a database created on my macbook pro. The file system used is XMF.

Cable TV - 720P or 1080i

Hi, just wondering what the best resoltion for regular broadcast cable TV is.
The TV is a Samsung, 50" 1080P. I just got a new HD cable box from TW, and it offers two options for resolution; 720P and 1080i.
Thanks,

Should also be an option that lets you match the resolution of the content you've tuned into.
Resolution should be 720p for 720p content, and 1080i for 1080i content. If you force the receiver to 1080i, it'll scale 720p and interlace it to 1080i, and then the TV will take 1080i and deinterlace it. You don't want that intermediary step for 720p content if you can avoid it.
Similarly, you don't want 1080i content to get deinterlaced and downscaled to 720p.

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!

Sorry to bump, but any ideas?

Calling "PAL" (OK: 50Hz) 1080i users of Matrox MXO...

I see that neither the Apple 23" ACD (nor the Dell 2407) truly supports 50Hz at 1920x1200 (1080); which means monitoring 1080/50i is not stricly correct.
Apparently there is nothing that can be done about this, but the effects of trying to monitor 1080/50i with the MXO according to Matrox is "minor", or maybe even "not noticeable". Occasional repeated frames, I understand.
Can any real users give me an idea of their experience please?
TIA.

Your understanding is correct. Here is what Matrox has to say about this issue:
"Since the majority of DVI monitors do not accept 50Hz, they don't lock to it; we decided to drive the DVI out @ 60Hz when working in PAL. If we were to send 50Hz to a monitor that did not accept a 50Hz signal, the result would be a black screen, and the client would not know why (We did a lot of testing with 50Hz). We decide to go with the lesser of the two evils, so to speak. I am looking at a software option to turn on and off a 50Hz output in a future release of our software, leave the decision up to the client."
The anomolies you see on the monitor when editing are a result of this 50Hz signal on a 60Hz monitor...and ONLY appear when looking at the footage on that monitor. They will not appear when you export to tape, or view on a PAL HD monitor. Only the LCDs.

Switched to 1080i 50hz, no image, can't return to native.

I have a 42" panasonic viera.
Just purchased atv.
I was just playing around with the settings saw 1080i50hz thought hey what is that, clicked on it now I have no picture.
Anyone have any clue on how I can bring picture back to the tv.
Let me know.
thanks

Some troubleshooting information is here: http://docs.info.apple.com/article.html?artnum=305175
From that article...
If your TV screen still appears fuzzy or black, you may need to select a video mode your TV supports. To select a video mode:
1. Press and hold both Menu and Menu up/scroll on the Apple Remote for about 6 seconds. Apple TV will cycle through different display resolutions.
2. When Apple TV reaches an acceptable display resolution and "If you can see the Apple logo, select OK" appears on your TV screen, press the Play button on the Remote.
Hopefully that procedure using the Apple remote control will let you get your Apple TV back to a video mode your TV supports.

Mac Mini + DVI- HDMI + Toshiba 42RV530U = black screen

Hi all, I have a new Intel Mac Mini 2GHz and a Toshiba 42RV530U REGZA HDTV that I'm trying to connect, with only a black screen so far.
I believe the DVI output on the Mini is working - I can at least get a picture with a DVI-S-Video cable, but it's obviously lower resolution. The DVI-HDMI cable works - I tried it on our cable box.
When the DVI-HDMI cable is hooked up to the HDMI-1 input on the TV, the "No Signal" warning vanishes, but it's replaced by a black screen. No amount of fiddling with SwitchResX has worked so far.
I've tried coming up with values for SwitchResX based on these numbers from the manual (don't know why the H Freq and V Freq give 2 values for each). I couldn't get exact values, but pretty close. I'd ideally like to get 1080p working.
Name Resolution Vert Freq Horizontal Freq Pixel Clock
480i 720 × 480i 59.940/60Hz 15.734/15.750kHz 27.000/27.027MHz
480p 720 × 480p 59.940/60Hz 31.469/31.500kHz 27.000/27.027MHz
720p 1280 × 720p 59.940/60Hz 44.955/45.000kHz 74.176/74.250MHz
1080i 1920 × 1080i 59.940/60Hz 33.716/33.750kHz 74.176/74.250MHz
1080p 1920 × 1080p 23.976/24Hz 26.973/27.000kHz 74.176/74.250MHz
1080p 1920 × 1080p 59.940/60Hz 67.433/67.500kHz 148.352/148.500MHz
I've also tried repairing permissions, rebooting many times, deleting the windowserver.plist files, zapping the PRAM, etc. SwitchResX identifies the TV as "TSB-TV", which sounds the same as other posts with different Toshiba TVs. I'm able to remote into the Mini via Remote Desktop Connection to play with settings, etc.
Any suggestions? Would a DVI to Component cable work? The TV does have an analog RGB in, but this won't support high def. Thanks for any help!
-Frank

An unforeseen twist... I tried hooking up the Mac Mini to a DVI computer monitor, also with no picture. When I hook up my Powerbook to the Toshiba via the DVI->HDMI cable.... Picture! So, looks like my new (refurbed) Mac Mini has a bad digital video output. Seems a little strange though, since the analog video output on it is working fine.
Off to the Mac store tomorrow.

MAC and FINAL CUT NOT RECOGNIZING SONY V1U Camera

The new Sony V1U camera (out this year) is not being recognized by my iMAC computer (this years latest model) and nor by the FINAL CUT PRO HD 5.1 ...Any suggestions?
I already called Mac/ Final Cut - they had the other models (Sony A1U and Z1U)listed as compatible with FC, but the V1U wasn't listed - I'm thinking since it's brand new, it's just not listed yet. We tried at Samy's camera to get it to work with their MAC/ FC but no go, and I tried different fire wire cable- wasn't the problem either. ANy help is appreciated - Do I need a Sony Driver or will I just have no luck hooking up the camera?

Just got the new HVR-V1U and it worked correctly out of the box with FCP 5.1.2 and iMovie HD on a Mac G5 Quad. IMovie saw the camera correctly right away as HD and captured that way; I set FCP to HDV 1080i60 and it captured correctly.
The camera setting for IN/OUT REC are:
REC FORMAT: HDV 1080i
COMPONENT: 1080i/480i (it auto switches depending on what's on tape)
i.LINK CONV: OFF
DOWN CONVERT: SQUEEZE (nothing happens since iLink convert is off anyway).
Note that the camera does NOT capture in Quicktime "New Movie Recording" unless I put it into DV mode or downconvert mode, but in any of those DV modes, the picture is squeezed regardless of my "squeeze, letterbox, or crop" selections.
The V1U will also capture to FCP and iMovie while just in camera mode: no tape recording, but just whatever the camera is looking at. Sounds like tapeless recording is possible, though there must be a tape in the machine. I haven't tried the HDMI through a BlackMagic Intensity (because I don't have one, and it doesn't work yet with G5's in any case), so I can't comment on the cameras raw performance. Camcorderinfo.com has a detailed review of the FX7 which has similar, if not identical video properties in the default modes.
I did some quicky video recording tests in HDV and captured them on FCP as HDV, then as camera downconverted DV (anamorphic). I then used compressor to convert each of those streams to mpeg2 (4.5 avg, 7.5 max) and the HDV to mpeg2 direct is slightly better, especially in vertical red bleed.
My only grip so far is that Sony did not include a regular mini-stereo microphone plug in, but only the XLR pair. For serious video work, you probably do want to use XLR mics; but it sure would be nice to be able to just plug in my cheapy Sony ECM-MSD1 to do casual recording in stereo instead of recording only mono with the included mic. Oh, well, we can't have everything, can we.

The new guide: change just because, STILL CAN'T SEE CURRENT TV REMINDERS!!

WHoever designed the NEW guide SHOULD BE FIRED IMMEDIATELY. WHY DOES IT STILL TAKE a dozen clciks to see a list of reminders OF CURRENT TV STATIONS THAT I HAVE SET A REMINDER FOR, but it's only a REMINDER LIST FOR FUTURE SHOWS?? DO you people actually think that someone watches a TV Commercial?? Only a **bleep** would watch a geico or progressive car insurance commercial a hundred times a day, day in, day out, on almost every channel. I SWITCH CHANNELS WHEN ANY TV COMMERCIAL COMES ON, and for some reason Verizon refuses to adopt the best thing about Comcast which is: YOU CAN PRESS THE REMINDER BUTTON, SEE A LIST OF ALL THE CURRENT REMINDERS YOU HAVE SELECTED, and simply arrow down to watch another channel until the commercial is done.
It took me 2 1/2 months to familiarize myself with your idiotic, moronic TV Guide, which uses batteries at an outstanding rate, and now everything is changed, why is that? WHoever made that decision should be fired.
The half channel guide now makes it impossible to read whats on the screen EVEN WITH A BIG SCREEN TV. And who cares about hi-def, why in the heck do I want to see the pores on someone's face?
16 clicks to bring up a reminder list, COMCAST DOES IT WITH A SINGLE BUTTON, why is that? Because Verizon doesn't want to be like COmcast?? Everything about Fios and Verizon is just a jumbled mess, too much stuff jammed onto one page, and everything has a similar name, why is that? I have over 6 lbs of Fios junk mail and still get flyers in the mail, most weeks it's multiple flyers of the SAME THING, so don't tell us about saving trees, because first of all there are 400% more trees today than in 1900, and secondly just like COmcast, SAVING A TREE DOESN'T INVOLVE JUNK MAIL.
   The new guide is change just for the h*ll of it, and it's just as crappy and hard to use. AND DO SOMETHING ABOUT THE REMINDER LIST< IT SHOULD BE ACCESSIBLE WITH ONE CLICK< AND SHOULD SHOW THE CURRENT, repeat, THE CURRENT LIST OF SHOWS, because we don't watch no stinking commercials.

TIMBO441,
You have been complaining about reminders for quite awhile. I have never had Comcast, and don't understand what it is that you mean by reminders. Since fast access to reminders apparently isn't a feature in any FIOS IMG it is a suggestion for improvement and belongs in http://forums.verizon.com/t5/Share-Your-Ideas-with-Verizon/idb-p/ideas ,
Are you viewing a HDTV? Most people see a reason for viewing in HD. I particularly see that as being so for many if not most FIOS TV users.
I haven't seen the IMG 1.9 on SD TV's.  People may see the new color scheme or exact font as poor and others may see it as an improvement. When I see it at a friend who had the Sneak Preview, the fonts size seemed about the same size to me. And in one of the threads someone posted all the guide screens, and again they do not appear to be any screens where the font is so small it can't be read even in the SD versions.
The new guide was meant to fix a lot of complaints that people had as well as to add features.   Among the problems addressed
Old screen guide had the last channel cut off by TV's as it was outside the so called Safe margins.
Top line of guide (perhaps on purpose) was completed obscured by info on what channels were being displayed (favorites etc)
Next 3 lines of guide were partially obscured by the small image of the current program
only 1 1/2 hours were displayed
guide didn't fill whole screen on 16x9 TV's
Guide is too dark. Yes, many complained about that and that led to the new lighter scheme that people now complain about.
Search to limited
Did they get things wrong. Almost certainly.
The IMG is also not just about the guide. Other features added
Native pass-thru. I.e.. Pass 720p channels as 720, and 1080i as 1080i. Your already could, if desired pass 480i as 480i/p.
Support eSata external hard drives on newer DVR's.
Support more than one multi-room DVR
Allow more control of multi-room DVR from other STB (and DVR). Includes starting and deleting recordings
Allow recovery of accidentally deleted recordings
So called program chaptering on DVR recordings
Parental control improvements

Intermittent HDMI signal on my Mac Pro late 2013

Brand new Mac Pro. Used for short periods of time for a week with no problems. After these few days, during a little bit longer session of work, I got display problems. Intermittent output signal by HDMI cable with image disappearing from monitor and coming back for some times. Problem occurred both in 720P and 1080i mode. The problem appeared and disappeared for several times. During one of this occasions also some bad green pixel remained stuck on the display.
Left the Mac on for all the night, this morning I do not notice any problem. Does anyone knows which kind of problem I got??
It seems to be a graphic card problem isn't it??
Thanks for help to everyone.
System: Mac Pro late 2013 - 6-core - 32 Gb ram - 512 Gb HD - FirePro D500 3 GB - Mavericks 10.9.5

Nothing connected to Thunderbolt ports.
Do I need to to reset SMC and PRAM anyway??
The Mac is connected to the Tv/monitor through my Bose LifeStyle.
Bose LS is setted to 1080i resolution and upscales the signal of the mac when in 720p.
Already tried at 1080i on 1080i and changed HDMI plug but problem shortly occurred.
Same device used in tha same way for years with Mini Mac without problems.
Is it possible there is some conflict between output of the Mac PRO HDMI and Bose LS??

1minute video distortion with iDVD-anybody encounter this?

I encountered a strange issue with a movie that I recently created in iDVD. Src was 1080i HD, downconverted to 720p and imported to iMHD, and then used within iDVD.
At about 53 minutes in the video (total ~1hr 40 min DVD encoded using Prof setting), there is a strange video distortion created - difficult to describe, but looks like say a 100x100 pixel movie upscaled to 720x480 with big blotches of color all over.
Src video imported to iDVD looks impeccable, and even if I recreated the DVD with diff src media at the 52minute mark, the distortion still shows up exactly for 1 minute around the 53 min (or 52.5 or 53.5 or 54 min) mark.
Really bugs me, as iDVD otherwise seems to do an OK job with the downconversion of the HD src file.
Anybody seen this odd behavior with iDVD? BTW, I burn to disc image, and both the image as well as the DVD show identical distortion at the same spot.

Bengt,
Thanks for the suggestions. I'll try trashing the iDVD pref file and re-do the disc image. I've already had to trash the iMovie pref file several times due to another bug there - I seem to have hit some max limit on # of cutaways+PIP inserts and it doesn't allow me to add another cutaway/PIP -- but that will have to be a different thread!
The file formats are the same throughout the movie - mixed HDV 1080i + AVCHD 1080i - and they are both downconverted to 720p using the native HD output format from iM09. All orig source and the 720p files look great without any artifacts. However, only the 1 min section as mentioned before has these really ugly blotchy artifacts when output from iDVD to 480i.
Unfortunately, I got the same artifacts/distortion at about the same point in the movie even if I tried a different iDVD theme (same movie length) or tried the output to Vid-TS folders...:-( This seems to point to a bug in the internal conversion to VOB...
I'll try your suggestion next - to trash iDVD pref and re-do the disc image again.
Thanks!

Generating movies with bad resolution

Hello all, Hello all,
I hope everything is going well and I apologize for my poor English. I am creating movies using IMovie’08 and sharing with IDVD. The final result that I get generating DVD is a video with bad resolution.
I have recorded all videos in 1080i using a SR12 Sony handycam and imported to IMovie with this resolution. I prepare an IMovie project and shared by Media Browser using large size, that I know is a smallest size than 1080i.
I set the encoding mode on IDVD to Professional Quality and generated a DVD. The result image’s quality on DVD is similar to a VHS tape! I generated 4 different DVD and tested all these DVD using different DVD players and different televisions and the result were always the same.
Please, can someone inform me what I am doing wrong or provide me some tips to get better results?
Thank you all in advance.
Regards,

The result image’s quality on DVD is similar to a VHS tape! I generated 4 different DVD and tested all these DVD using different DVD players and different televisions and the result were always the same.
No matter what you send to iDVD will be encoded as SD 640x480 "square" pixel content to a "720x40" rectangular pixel data matrix. In other words the best resolution you could expect would be half of what you started with and at the third generation of transcoding. (I.e., 1080i AVCHD => 1080i AIC/AIFF => 960x540 H.264/AAC => 720x480 (640x480) MPEG2/PCM.)
can someone inform me what I am doing wrong or provide me some tips to get better results?
If you are expecting HD quality on a standard DVD, then your expectations may be too high for this work flow. Using a more professional editor and/or burning as HD optical content may better suit your needs/expectations.
