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.

CG output - 720p or 1080i

I am working in computer graphics, so I am rendering a sequence of images to be edited in FCE HD. 30fps, going to digital tape for projection on theatre screens.
I've determined that hd video will be fine. Now I need to determine which type, 720p or 1080i. Since I'm not coming from a camera, that isn't an issue. But I do choose the size of my renders, 1920 X 1080 or 1280 X 720.
Any input on the pros and cons of using either one? I assume that bigger is better, but what does interlacing or progressive scan really mean in practical terms. Does one limit tape options? Should I render the larger size, so I can do either?
Thanks in advance.

Different film festivals accept different formats for exhibition: miniDV, digibeta, DVCAM DVCpro. So it could be anything! Most seem to accept DVD. So I would like to be prepared to dub down as needed.
So, I don't plan on going as high as D-1, and I haven't studied the costs involved, but perhaps digibeta or DVCAM.
To get it there I will probably take my hard drive to a facility which could output it for me, whether it's post house, or a friend with a production facility.

720p and 1080i in same timeline FCP 5.1.4?

I've tried to find an answer to this in the discussions, but no luck, so I hope this hasn't been asked a million times before.
Can I edit 720p and 1080i files in the same timeline? If yes great! On to the next question.
Once I complete the edits, how should I output the final cut - in 720p or in 1080i? And if the answer is 1080i do I need to upres the720p and how do I do that?
I have FCP 5.1.4.
Thanks!

Can I edit 720p and 1080i files in the same timeline?
In FCP 5.1.4? No, not without rendering one. Sequence settings match one codec, so anything else will need to be rendered. FCP 6 solved this..open timeline is available. It also automatically sets the sequence to match the settings of the first clip dropped into it.
If yes great!
sorry.
Once I complete the edits, how should I output the final cut - in 720p or in 1080i?
Depends...what is your delivery requirement? What do you have more footage of...720 or 1080?

Mixing 720p and 1080i footage in a sequence

What's the best choice to edit a movie comprised of clips shot in 720p30 and clips shot in 1080i60? "Upscale and interlace" the 720p footage or "downscale and deinterlace" the 1080i footage?
Using easy setup, one has the choice to create either a 720p or a 1080i project, and when adding a clip to a sequence in this project, the clip is automatically converted to the project's format. Therefore, this is something that needs to be decided ahead of time. Or is it possible to change the project's settings after attempting to export the sequence if the result is disappoining?

All right, but assuming that I have the choice of output format (and I do), what is most likely yo result in the best overall result? Interpolating (720p output) or extrapolating (1080i)? Intuitively, I would think that interpolating is most likely to result in less artifacts than extrapolating. So on this measure, a 720p output of a mixture of 720p and 1080i footage would be more recommendable than a 1080i output.
The good news is that you are saying I can change this in my sequence at any time.

Given a choice: what should I mix 1080p with -- 720p or 1080i?

I have a three-camera shoot coming up with two 1080p cameras.
The third camera can be either 720p or 1080i.
There's no way we can upgrade the third camera to 1080p.
I'm being asked to give a recommendation on 720p or 1080i.
So which format (720p or 1080i) mixes better with 1080p?
Which one will output better to a DVD?
I'll be cutting in FCPX.
Cheers.

Thanks Al. Wow - it's been so long since I've recorded a DVD video, that I had forgotten about the SD restriction.
Setting aside the DVD issue, what would you reccomend would look better online when streamed in HD?
1080p material mixed in with 1080i or 780p?
Cheers.

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.

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?)

Advice Exporting 720P into 1080i

Hello
One of my students has managed to start editing his HDV 1080i 50 footage in 720P 29.98FPS settings. It plays fine for him off the timeline in his Preview window but when trying to export it to HDV 1080i 50 for use in our studio play out system it doesn't work at all.
I tried exporting it to Apple Pro Res HQ too but still nothing.
Our play out system is essentially FCP 3 playing through an AJA HD-SDI card into a For-A vision mixer.
I've been using FCP's Export Conversion process.
Should I attempt using Compressor?

You should copy all the content of the timeline he's been working in, and paste it into a timeline with the correct settings. Then you'll have to remove any scaling that was done from editing in a smaller frame size, and any timing alterations from the differing frame rate. Better to do this than to try and fix it on export. Right now you're going through two conversions. Neither one of them ideal.

720p to 1080i in compressor

Hello all. I am doing a commercial and the footage shot and the timeline is 720p. The TV station we are using wants 1080i/60. How can I do that in compressor? I did change it to 1080 but don't see how to indicate that I want 1080i. Also, compressor wouldn't let me change the frame rate either. Thanks in advance!

23.98 to 29.97 via Compressor:
1. Drop clips you want to convert into Compressor
2. In Compressor, select your video then right click and choose NEW TARGET WITH SETTING > APPLE > FORMATS > QUICKTIME > APPLE PRORES 422 (HQ). Or pick whatever codec you like to work with.
3. Click on that newly created compression setting to open it in the Inspector window. Click the Encoder tab. Click the Video: (Settings…) button. Make the frame rate 29.97. Check the interlaced box. Set it's drop down menu to Bottom field first. Click OK.
4. Click the Frame Controls tab. Set Frame Controls to On. Set Output Fields to Bottom first. Leave Deinterlace on Fast. Leave Adaptive Details checked. Leave Rate Conversion set to Fast. Leave the Set Duration to: on 100% and make sure it's radio button is selected and NOT the "so source frames play at 29.97 fps" button.
5. Make changes to the Filters or Geometry sections as needed. Those settings listed above are the ones critical to getting the proper 3:2 pulldown added.
6. Submit the compression, then bring the resulting video back into Final Cut Pro. Place it in a 29.97 timeline and make sure you watch it on an NTSC monitor to verify that it looks good. If you step through it frame-by-frame you should see the familiar pattern of 2 split/interlaced frames followed by 3 whole frames. This is a very important step. I tried many solutions that looked OK playing back on the computer monitor, but looked terrible on the NTSC monitor.

720p or 1080i

My TV supports both.
Which is supposed to give a better picture?
I can't tell the difference.
b.

Winston, I agree with you.
On old fashioned interlace sets, the 525 line sets, only 480 lines are available for the picture, the rest were for the flyback part of the signal.
A CRT uses two sets of coils, one vertical set and one horizontal set. The electron beam passes through the magnetic field created by the coils so that it scans back and forth across the screen. As it scans back and forth, it also moves up by the vertical deflection. The scan lines are slightly slanted. After 240 scans across the screen, the signal is blanked out as the beam is deflected back to the bottom of the screen. During the downward deflection, the horizontal deflection makes 22.5 more scans. this makes a total of 262.5 scans.
The next frame, which is actually the same as the first is scanned, but since the scan starts at the bottom center of the screen instead of the bottom left, the picture is painted a half line higher. So the 480i of analog broadcast is actually only 240 lines of resolution. All of this is based on a TV camera broadcast camera.
A film camera records 24 pictures per second. In a movie projector, each frame is lit twice so that appears to be at 48 frames per second. The 48 makes the picture steady, our eyes can't detect the flicker. 8mm home movie camera recorded only 16 pictures per second but home projectors used a 6 slot shutter to project each picture 3 times. The 3:2 pill down is a way to match the 24 pictures of a movie film to the 60 frame per second broadcast rate. One picture is shown twice, the next one 3 times.
Information on how 1080i and 1080p work is a little sketchy, but it appears that 1080i may only be a 540 line picture broadcast twice. If that is true, the 720p would be better than 1080i, and 1080p is better still. Right now, there are no 1080p broadcast sources. As far as broadcast TV is concerned, the TV will sync to either signal. Most TV shows and movies are broadcast in 1080i, but sports events are broadcast in 720p for more clarity.
I bought a 1080p set, not for now but for future changes. Since I only buy a TV about once every 20 years or so, I didn't want it to be obsolete too soon.

HT203477 Trying to make a Master copy. But I keep getting this The operation could not be completed because an error occurred when creating frame 2846 (error-1).How to correct it find the frame or?. I shot both 720p and 1080i also pictures Trying to do 10

Trying to export my project as a mastercopy but keep getting error message "creating frame 2846 error 1" I don't know what to do? do I try and find the frame and if I do how.

I have the same error but i dont know how to thrash the render files and switch off background rendering.
my problem is in the frame 6150 how to fix this problem. i need your help because i have to present this work for tomorrow

Is there a significant difference between 720p, 720i, 1080i, 1080p?

Hi,
I'm in the market for a new TV, and as I'm sure you're all aware, there are quite a few options. The subject of this message pretty much says it all. I've heard that the human eye can't percieve the difference between the listed types. Is thatt true or is that just what people that are cheap say? Thanks for any help.
Best Regards,
Tom

It depends on the viewing distance and TV size. What size TV and what will your viewing distance be?
That said, the price premium for 1080p is so little nowadays that unless you're getting TV around the 32" or smaller range, I would make sure to go for 1080p.

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!

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.

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.
