1080i or 720p

Hi,
I've recently purchased the ATV and it's connected to my Samsung HDTV via HDMI. I've got a 720p TV, that also supports 1080i, but I want to know which resolution setting will give the best performance.
Any advice?

Hi there,
so, 100hz is fairly popular in Europe with EDTV resolutions. I do believe tv actually has a setting for it under it's resolutions. 100hz is basically a 'line doubling' method (a still multiple of original AC line frequencies).
There is no 'direct' correlation to the resolution. This means that your picture refresh rate is 100hz (versus regular PAL at 50); giving a more stable, flicker-free picture. The same as for resolution goes; you want to match as well as possible to minimize the amount of conversion (and frame rate conversion can get complicated, as you don't want any frames inserted or doubled or taken away; a problem with NTSC/PAL conversion).
To make it more complicated , refresh rate is NOT the same as frame rate necessarily (a film projector for example does 24 frames a second, but would likely have a refresh rate of 48hz or higher for stability)
Soo... I would, again, use whatever looks best to you. It's common for LCDs to be an off-standard (that is, not adhering to HD resolutions) resolution. Your TV will have to convert either way - up OR down. In your case, I would probably think 720p is best as well, as you'll stay in the non-interlaced domain. In the end, if there is no simple rule (i.e. least conversions) then whatever looks best to you is best
Best,
Dan

  • 1080i to 720p

    Is it possible to convert a video from 1080i to 720p using FCP?

    Convert it internally? Or upon export? What exactly are you trying to do?
    If you want to convert a 1080i clip to 720p, the Compressor ADVANCE CONVERSION options are the best way...

  • Mixing 1080i and 720p

    Hi,  I have a shoot coming up where I'll need a second camera.  My primary camera for this project so far has been a JVC GY-HD200UB, shooting HDV 720p 30fps.  Both of my second camera options only record HDV 1080i (a Sony HVR-A1U and Canon XH-A1).  I'm leaning towards the Sony because it seems to handle low light a little better and it will be a dark location.  How should I handle the 1080i footage in regards to my 720p project?  Down convert it to a new file, then import?  Just bring it into the same project and scale to fit?  Will it be glaringly obvious that some shots are interlaced?  Has anyone here mixed footage?  What were the results?  Thanks! JB

    Hi,
    I'm using CineForm AVI for both 1080i and 720p.
    The best I've found is to bring 1080i in the 720p project as a separate Sequence
    and then scale one down on 720p timeline.
    Mixing both on same timeline drive Premiere CS4.1 crazy in my case.
    But I didn't make a lot of research.
    Good luck

  • 1080i and 720p footage going to 576i DVD?

    Hi.
    Just getting my head around the best way to attack this.
    I have a pile of 1080i and 720p footage which needs to be edited together with the final destination being a 576i DVD.
    Now, being a country that uses interlacing and as at least half of my footage is interlaced, it seems a bit of a waste to
    convert the 1080i to 720p and then convert it all back to interlaced again with the DVD encoding. So wondering about the merits of an intermediate 720i timeline? So the same settings as the 1080i but 1280x720 dimensions.
    Is this a good/bad/stupid idea? Any better way to do this?
    Thanks a lot

    1.) They will be the same aspect ratio (16:9, square pixels), but each will take up more or less room within the frame than the other.
    2.) If you start a 720p sequence, then yes, anything larger than 1280x720 will need to be reduced to fit entirely within the frame.
    3.) You can select "Scale to Frame Size" by right clicking on the video clip, or manually resize the video through the source video's Effect Controls box. In addition, with the advent of CS4, Adobe has added a nifty little feature that was absent from earlier editions of Premiere, including CS3, and that is "Maximize Render Quality." This feature is checked from within the sequence settings dialog box, or selected from your export settings, and ensures that any footage that is scaled to fit the native resolution of the sequence will be handled appropriately so that it maintains maximum visual sharpness and resolution.
    Keep in mind that there are different flavors of 720p and 1080i, so in future posts it would be helpful to designate which one you are referring to. For example, HD is defined as having a resolution of 1920x1080, and 1280x720 with an aspect ratio of 16:9 and a pixel aspect ratio of 1.0, or 1:1. Panasonic DVCPROHD, through the use of line doubling, is actually 1280x1080 (1.5 pixel aspect ratio), and 960x720 (1.33 pixel aspect ratio), and Sony's HDCAM/XDCAM HD is 1440x1080 (1.33 pixel aspect ratio). Knowing exactly what format you are shooting in and what the native resolution you will be editing in will help maximize your results within the editing software and ensure that your video is not visually distorted. It will also offer you realtime playback direct from the timeline without the need to render, presuming you have a system that is up to spec.

  • 1080i and 720p mixed time line

    I asume that that you can have mixed formats on the time line but one format will have to be rendered each time its added the the t/l. the formats are 1080i amd 720p.
    cheers angus

    No...they are both 16:9. Just resize the other to match.
    Best to capture one in the other format if possible, to avoid rendering.

  • 1080i vs 720p

    Hi All,
    I'm sad today cause I did a test on 1080i vs 720p and the result was pretty nice on 720p in term of motion blur. The result was the 720p shows the pretty smooth of every movement of the subject (talent). In fact, the 1080i, wow...terrible motion blur though I've De-Interlaced or Progressived export from Compressor!
    So, your precious opinion, do 1080i possible to producing the smoothness that 720p given? Do FCP or Compressor might able to smooth the motion blur? Or, any great suggestion to me? Thanks and appreciate!

    Brad Wright,
    Thanks!
    I've got the choice to record @ 1080i or 720p from my device. In fact, the final master might be use in 2 ways--Web & DVD production.
    So, what s'ld I go for the footage setting? 1080i?
    And, 1080i though will provides the bes slow-mo, in fact, unfortunately, seems I did an ugly slow-mo (down to 50%), Bad motion blur...why?
    AVCHD, seems Apple Pro Res or AIC is what I can go for @ the Transcode stage...no setting c'ld be do? Still, What s'ld I use (setting) for my timeline/sequence?
    I really need help...

  • Convert 1080i to 720p

    I´ve got some 1080i movies (even self recorded) and would like to play them on my AppleTV.
    Can I use Compressor to convert the 1080i to 720p? Should I use FCP? What should be the correct settings in Compressor?
    Thanks to everybody trying to help me!!

    Compressor is best for this. The easiest thing to do is use the Apple TV preset located in the Apple > Apple Devices section of the Settings window.
    The default settings should give you decent results but if you are looking for a high quality conversion, try switching on Frame Controls in the Inspector window.
    Set Resize Filter to Better, Output Fields to Progressive and Deinterlace to Better.
    It is tempting to just put everything on "Best" but this will take a long time to encode. "Better" will be sufficient for most cases.

  • 1080i to 720p via After Effects Best Practice?

    Hi, I have some footage which was shot at 1080i, the required output is going to be 720p.  The problem is that I would like to use some of the extra frame to reframe some of the shots and as there were two camera's used, the colour varies, so I will also need to fix that.
    My initial plan was to cut the sequence in Premiere using a 1080i preset then DL the sequence from within After Effects using a 720p composition.  From here I can do the reframing and colour work.  However will this take care of deinterlacing? Or does anyone know of a better workflow to get the results I need?
    Cheers

    Just to update this incase somebody else finds it useful, decided I would have to spend some time testing the best route before actually starting the project.
    So the source footage was shot @ 1080 50i AVCHD (Cannon Legria HF21 and Panasonic HDC-HS700).  The desired outcome of the footage is web distribution, so mp4 @ 720p 25fps.
    During editing I really wanted to re-frame some of the shots and also give some motion to some i.e. slow panning.  On top of that the two cameras used, always seem to give different colours in post - no matter how much you try to match the LCD display's during the actual shoot.
    Ok so the problem I initally encountered was with jaggered edges when deinterlacing (can't afford any third pary plugin's at the moment).
    So that's the background - I tried a couple of different routes, however the best way I have found is to edit the footage in Premiere using the default 1080i AVCHD preset, keeping the Cannon footage on video 1 and the Panasonic footage on video 2.  Once all the editing is done, duplicate the sequence and in one enable video 1 and in the other enable video 2.
    Then jump into After Effects use dynamic link to open the the two sequences - here I open the interpret footage settings and make sure that the field order is set correctly and that 'Preserve Edges' is ticked.
    I then created a new composition with 720p settings and put the the two Premiere sequences in it.  Then it is just a case of using keyframes to reframe the footage.  Also it allows for applying different colour correction to the footage shot on each camera.
    I also found that this process decreases the jagged edges found going from interlace to progressive.
    Hope that helps someone, or someone can tell me I am going the long way round

  • 1080i vs 720p vs DV Widescreen

    Hi,
    I've created a project using footage from an HD Camcorder (AVCHD). I actually used iM 09 to access the SD card and save the content. Because I'm a lot more comfortable using iM6 HD (iM 6.0.4) I decided to "Make movie" from iM 09 and then import the result into iM6. Unfortunately, when creating the new movie I selected the DV Widescreen option in error.
    My question is, should I have selected either of the 720p or 1080i options instead and if so:-
    1. Which of these latter 2 is better?
    2. How much difference in quality is there between DV Widescreen and these latter two?
    3. Have I succeeded in making the HD content of my HD camcorder irrelevant?
    Many thanks,
    TonyT

    Many thanks for your response, Roxco.
    That's very helpful advice.
    I'm in "PALland" too and I was wondering if I need to start the project from scratch again using the 720p (HD) option in iM6. I intend to burn the finished project to DVD for distribution to a group of friends. Hopefully, the HD quality will be retained???
    Thanks again,
    Best!

  • Converting 1080i to 720p

    I have a Nikon D90 that shoots in 720p at 24fps and I just purchased a Canon HF-11 that shoots in 1080i which also has a 24fps selection. Can I use Mpeg Streamclip to downscale (not sure if that's the correct terminology) the 1080i footage to 720p? I would like to make a video in 720p in FCE but I'm not sure if I'm degrading the 1080i footage too much or if I'm going to run into some kind of problems later on when burning to DVD.
    Thanks,
    Ray

    Well, there are multiple issues here.
    One, you can use MPEG Streamclip to convert the video to *Apple Intermediate Codec* for editing in FCE. But don't expect miracles. Your D90 stores video as *Motion JPEG,* which is obsolete vis-a-vis today's video standards. You will notice the quality difference compared to your HF-11.
    Two, FCE only supports 720p30, so that is another issue you will have to deal with.
    Three, you could use Graeme Nattress's Standards Conversion plugins to deal with 3:2 pulldown. I'm not completely sure it works with FCE, so you should contact Graeme to verify before purchasing the plugin.
    Four, your HF-11 is an AVCHD camcorder, and I would not recommend mixing 1080 and 720 video in the same sequence. Even after going through the conversion hoops, you will see a difference.
    Five, in order to create a hidef DVD you will have to purchase Toast and a Blu-Ray burner. Regular DVDs are all standard def; you can give iDVD hidef source material but you will still get a standard def DVD 'cause that's what they are.

  • Using 1080i and 720p footage for theatrical projection

    The 1080i footage was captured with AIC and the 720p with prorez 422. Can anyone tell me the best sequence settings for highest quality output (through DVI port at theatre) and for reduced rendering times?
    Should the clips from one or the other be rendered and/or exported with certain sequence settings to better match? Any significant loss with this?
    I also have to make SD dvds, but that's not a pressing concern.
    The 1080i (Sony V1u) footage could be recaptured, but only if a significant quality improvement could be made another way. The camera was rented.
    I've spent hours researching this with little results. To say I would appreciate any help would be a tremendous understatement!

    The various HD files are send to me on a drive from the producer, so, they're in the system as HD. It seems that If I build an intro in HD using the native files, the nest that into the SD sequence, I'd have less rendering. However, I'll have mostly 4:3 screen ration with a letterboxed intro to the older clips. Does going from letterboxed video to 4:3 video bother anybody? Is it considered OK? I see it on the news, but not in regular programming.

  • AppleTV with a 480p/1080i (non 720p friendly) TV

    I have an older HDTV -- 480i/480p/1080i component input only. How will an AppleTV handle 720p files since I cannot use 720p as an input option?

    So it upscales 540p and 720p to 1080i via component? If so, is the upscaler very good?
    Additionally, if I view JPGs (mostly 6-8mp), do they display as 1920x1080? 704×480 upscaled even on a 46" TV looks pretty bad.

  • Automatic switch between 720p and 1080i

    I just got FiOS installed today and as I was going through the menu, I noticed that for the video resolution, you are forced to pick a format. Is there a way to set it up so that the STB automatically picks the resolution that the broadcaster has chosen? I don't want to watch everything in 1080i or 720p. I'd like to watch it as the channel has chosen to send the signal
    Solved!
    Go to Solution.

    Unfortunately no.
    My suggestion is to try both and stick with the one that looks best on the most channels that you regularly watch. I have a 720p LCD but the 1080i setting in my DVR provides the best HD picture by just a little bit.
    Also, you have an option you can set for the SD channels (SD Override). I prefer OFF, which means that the SD channels are sent to my TV also using 1080i. This results in a slightly worse SD picture than using 480i or 480p, but eliminates the extremely annoying 2-4 second delay (HDMI re-sync) when switching between HD and SD channels. Again, I suggest you try the various settings and pick the one that you like best (or hate less?)

  • Can I output a 1080I & 720P Quicktime mov from NTSC source video in FCP?

    I have a client who wants me to take NTSC Digibeta source masters and create 1080I and 720P Quicktime files. I believe that FCP will let me do that, but wanted to make absolutely sure before I proceed.
    Thanks guys!

    Blowing up an SD source to 4 to 10 times larger than the original? Can you say, "eeeew?"
    Yes, you can...if you use COMPRESSOR...and the Advanced Conversion options. And choose custom controls to make all the conversion settings to be BEST. This will take a WHILE...but it will work.
    Or...buy a Kona 3 and a high speed RAID and the Kona will upconvert for you when you capture.
    Hold on...what SORT of files? Like the 720 and 1080 TRAILERS you see on Apple? Or HD Deliverable files?

  • 720p vs 1080i  Simple question.

    I shoot with the JVC 700U which captures in native 720p. I have been told I should shoot in 1080i by some folks. Some of my work is on cable, other on the web. If you have noticed other posts by me, my system has trouble with 720p and I am unable to figure out why. So...pros and cons 1080i vs 720p? Very little of my work is high end, mostly local stuff. I just would like some opinions from you guys. Stay native with 720 or change it up to 1080? Thanks for all of your help.
    Best.
    Tom

    I have always been a big fan of 720p. Why? Two reasons, one, many of the 1080 formats, especially when they first came out, were anamorphic, which is a pain in butt to deal with. Second, 1080i is interlaced. Interlacing is so 1950s. Really? Do we still have to to cling to half century old technology? If you can do 1920x1080p30 then go for it, otherwise I don't see the point. Interlacing is a world of hurt for no benefit.
