Question about 720 x 480 (widescreen)

Hi,
I'm working with FCS2, that is Final Cut 6 and Compressor 3.
I shot footage with an HV20, in HDV, 16:9 and 24p. My goal is to produce an SD (720 x 480) mini dv tape that looks good, not squeezed, I think I will need it to have the black bars, right?
I captured and edited as HDV, and followed the workflow by Apple (http://support.apple.com/kb/HT2410) prior to editing. Now, I have footage 24p, HDV, edited. I've tried to produce an SD sequence, so I applied the Bonsai method http://www3.telus.net/bonsai/Step-by-Step.html in FCP, it seems to look good.
However, I'm stuck when it comes to Print to tape. I've tried it but I get this squeezed image everytime. Please, I've trying here for hours now, searching and testing. I need an SD mini dv tape that's not squeezed in the image. The downconvert looks just fine, it's the squeezing I can't get right.
Also, I remove the pulldown through Compressor but when I Print to Tape, it's in 29.97 again! Is this normal? Does this mean I can't have 24p on tape?
Thank you so much in advance

You'll want to create a new sequence using the DV/DVCPro NTSC Easy setup. Do NOT use the Anamorphic setup. Drop your existing clips or sequence into the new sequence, do not answer Yes to matching clip setting. This should create a letter boxed 4:3 720x480 version of your HDV sequence.
DV tape can only record at 29.97 frames per second, that's set by the original design standards. DV cameras that have a 24fps option have to add a 3:2 pull down before recording to tape.
You CAN build a 16:9 24fps DVD from your HDV sequence that could actually be better quality than a letter boxed DV tape @ 29.97.

Question about Dell-18.5" Widescreen Flat-Panel LCD Monitor-IN1910N

I just bought this monitor, and now realize it doesn't have speakers in it. I don't see where I would add them. Can anyone help? Could you please tell me know kind of speakers would work, and how I would attach them? Kind of defeats the purpose if I can't listen to music or watch movies. Thank you!

Question about Tritton AX 720 Dolby Digital Surround Gaming Headset

Hello, I have a question about the AX 720 that I hope someone can answer. I emailed Tritton and I'm not sure they understood what I was asking, so Ill try here. Ok, my question is this, Will I get audio through the headset if my set up is this: My X-BOX 360, my PS3 , and my Direct TV box are all hooked up to my TV via HDMI. My TV has an optical audio output, so if I hook up the AX 720's amp to my TV with the optical cable will I get the audio that is coming from that output into my headset? I'm using the Tritton AX 180's now hooked up almost exactly the same, except instead of the optical out, I'm using the red and white out that is right next to the optical out, and it works perfect. I get full audio from all 3, and the only time I have to change any cables is when I want to chat, but thats rare. I'm looking to upgrade to the 720 because I'm on my 3rd set of broken AX 180's. Ive read several reviews about the 720's and a few of them said that if your TV has an optical output that you can use that, and I hope its true. I hope this question makes sense, and thanks in advance for the help.

@Rockadile: You are totally right about the AX 180's breaking, like I said Im on my 3rd set. Thankfully for the first break it was within the return period, then I made sure to buy the warranty when I got the second. Now that the 3rd has broken in the same exact place Im done with these. The problem is my heads big (wide), and because of this theres extra pressure on the plastic piece that connects to the ear piece. I had to make a custom metal bracket to fix it. What I did was take 2 pieces of flat metal and bent them into the shape and angle of the plastic that attaches the earpiece, then I electrical taped them VERY tight. So basically instead of the plastic getting the stress, the metal does. And it worked great up until now, its breaking just below the adjustable part where the plastic goes into top of the headset. I looked at the AX 720's and it seems like there alot wider and stronger in that area. But if I do get them I will be sure to buy the replacement warranty. Sucks having a big head!

Why does my 720 x 480 clip not fit in my 720 x 480 sequnce? (Black side bars)

Hopefully someone understands, I'm trying to make an edit with some Mini DV Standard Definition footage in Premiere Pro CS5 and Im using a Mac with Lion 10.7.4. All of the clips are .mov and 720 x 480 and I have the sequence set to DV - NTSC 720x 480. I'm noticing that the clips just about fit the frame size except for these thin black bars on the sides. It became more noticeable when I tried using a video transition as seen in the photo below. The bars do not show when watching the clip in quicktime only when in a premiere or in an exported video. This also happens in After Effects as well. Any help on getting rid of these black bars woud be appreciated. Or are they supposed to be there?
(Using the center split video transition)

what additional parameters do I need to give you that would diagnose this problem? Or are you just being a snobby forum dude that has to give the person in need of help a hard time. If you can't help me with the information I've given you probably dont know the answer to my question. How about I rephrase my question. Have you ever seen a problem like this occur, and if so what setting or "parameter" was incorrect that caused this?
I do not mean to seem snobby, but what I am missing is the PAR of the Source Footage. If it's been posted above, then I apologize, as I just did not see it (even on re-reading the thread).
As for my knowing the answer, you could be correct. However, it sounds like there is a mis-match between the PAR in your Sequence, and that of your Source Footage. The "small black lines" sound like the difference between a Sequence PAR of 1.212 (Widescreen non-square pixels) and PAR of 1.0 (square pixels). But, then I could be wrong on that, and it's the reason that I wanted to be able to compare the PAR of the Sequence, and the PAR of the Source Footage. If we rule that out, then we need to look elsewhere for a solution.
Good luck, and sorry if I seemed the least bit snobby, or rude. I am just trying to help you get 100% full screen.

Mixing 1280 X 720 quicktime files with 720 X 480

I have a question about the best way to mix footage of different resolutions in Final Cut Pro HD? I am working in Tiger 10.4.5 and I will only need to output to standard 720 X 480. I'd like to get all of my material into a consistent size before editing the film. Most of the HD footage is already captured to a Lacie Drive. What's the best way to downconvert this footage?
Thanks for any advice, cj

Export with QT Pro to your current format. So from HD to DV/NTSC.
Same to lose all that resolution.

720 x 480 vs. 640 x 480, which one to use?

This is not a iMovie specific question, but it is related. I always thought that SD was 640 x 480 and I always format any stills I use for that format. Everything has been fine. 640 x 480 = 4:3. Recently somebody said that you should format for 720 x 480, even for SD. I'm a little confused, SD is 4:3 while 720 x 480 is 3:2. If you use this format will the edges get cut off on a SD TV, or will the image get squished?
Thanks
Chris

where the 720 x 480 came from
For historical resons there is some "extra room" around the video frame. This is the root of all kinds of errors when people calculate aspect ratios:
Standard definition NTSC DV's sampling matrix is 720x480 (that includes the "extra room" around the image although often there is content in all pixels). DV uses rectangular pixels -- the pixel aspect ratio is 4320:4739 = ~0.912. So the pixels aren't square and you have to scale the image to see the correct proportions. iMovie and a TV set do this automatically but sometimes the poor user might see an unscaled image and think something is seriously wrong...
Notice that inside (and outside!) of that 720x480 sampling matrix the actual active picture size is 710.85 x 486. Weird but true.
Now, to see the correct proportions you have to scale rectangular pixels to square pixels. You usually do that by multiplying the horizontal pixel count by the pixel aspect ratio:
So the square pixel horizontal sampling matrix becomes 720 x (4320:4739) = ~656. So you should scale 720x480 to 656x480 to see the correct proportions on a computer monitor.
The same calculation applies also to the actual active picture size: 710.85 x (4320:4739) = 648. So the square pixel actual active picture size is 648x486 which is EXACTLY 4:3!! THAT is the 4:3 ratio we talk about -- not the 640x480 which is just a cropped value of the former weird size.
The same principles apply also to 16:9 ratios.

Why does 720 x 480 != 720 x 480?

When I open the Media Encoder to export my project as an FLV (using On2), it shows the original is 720 x 480 and it looks OK. But the Output panel shows the frame size is smaller, even though it's also listed as 720 x 480. Yes, both panels are set to 100% view.
What's going on?

Please post screen shots so we can see what you are talking about.

Is all 720 x 480 video 4:3?

Is 720 x 480 video always 4:3? What about video shot with a camera that has a widescreen adapter that is shot at 720 x 480? Is it still considered 4:3?
Thanks.

Hello stanwelks,
the short answer is: No. NTSC SD video is always 720 x 480 ... the difference between 4:3 and 16:9 video is the pixel aspect ratio: (almost) square vs. rectangular.
http://en.wikipedia.org/wiki/Pixelaspectratio
I don't have any practical experience with widescreen adapters, but my guess is that what you will get is letterboxed 4:3 footage, even though with better quality than when simply using the camcorders built in 16:9 conversion.
hope this helps

IDVD 08 insist to transform NTSC 720 x 480 files in 640 x 480!!!

iDVD 08 insist to burn NTSC 720 x 480 files in 640 x 480
And of course smaller with a black box…
I've tried everything in vain.
It's the same If I select widescreen or 4/3 menus…
My files are mp4 H.264 files.
I'm quite desperate since I don't get WHY iDVD wants that DVDs look like 50 years old TV shows !

A TV uses rectangular pixels: 720x480.
A computer uses square pixels. So, those same pixels (720x480) are actually 640x480 and a computer. So this is normal.
The quality of your DVDs would be a separate and subjective issue. However, I can suggest that you NOT use H.264 (very compressed format) as the format for iDVD (which does it's own compression) to work with. I would give iDVD a DV or AIC file.

720 x 480 DV sequence export aspect ratio always wrong. How come?

Finally finished editing one of the sequences and want to export and test it,
But no matter what settings in QuickTime Conversion (or just QuickTime Movie) parameters I do (e.g., Size), the exported file always seems to be in the wrong aspect ratio.
I need to have the resulting movie burned on DVD for showing.
Any tips appreciated.
Sequence settings are 29.97 fps, 720 x 480, DV/DVCPRO NTSC, NTSC CCIR 601, 48 KHz.
Thanks.

Hi guys.
OK, I hate to use the words "I assumed" because you know you are going to get into trouble for saying them! But... I guess this is how the newbies like me learn the difference between assumptions about certain theoretical concepts and their real-world exceptions.
"I assumed" that in FCE/FCP that if I set a sequence's settings in the new "multi-format" timeline, that FCE/FCP would keep that sequence throughout the timeline, and automagically conform whatever clip formats that I put into it, into the sequence's formats. And therefore that I no longer need to worry about the original format of the clips, and just focus on using the sequence's settings as the final assembly format.
(Please advise if this assumption is incorrect).
Thus, my sequence settings above
29.97 fps, 720 x 480, DV/DVCPRO NTSC, NTSC CCIR 601, 48 KHz
combine footage from
1) HDV camcorder imported into iMovie 08 as 960 x 540 (the "lower resolution" option from iMovie '08 import), 16-bit @ 48 KHz (Big Endian), 25 fps
2) AVI files (DiVX 512 x 384, MP3 at 44.1 KHz, 23.98 fps)
The AVI DiVX footage is actually television program recorded content. The HDV footage (converted to 960 x 540 resolution by iMovie) is what I shot myself.
What I am doing is trying to cut in my HDV footage (home video) into the TV show's content to create a humorous entertaining video to show family and friends.
So after editing this thing for the past week, I am now ready to test on the target devices (iPod, DVD).
The edited cut plays fine in FCE's preview.
However, on export, the original TV show's content is in the wrong aspect ratio. That is, it is a bit wider, pulled out horizontally. Not significantly wider (e.g., not like 4:3 pulled to 16:9) but just not in the proper aspect ratio. I can't really tell if the superimposed HDV (that is, 960 x 540, not actually 1080i) footage is pulled out too (most of that is shrunk down or otherwise distorted, in the final assembly).
I have spent two days now exporting to many different formats, etc. but none of them seem to work. I just don't understand why. I would have thought that "forcing" the pixel dimensions using QuickTime Conversion's "Size" option would brute-force ensure the resulting video has the exact required dimensions and thus aspect ratio, but it does not seem to be my result.
Help much appreciated!
Thanks.

If my imported video files are 720 by 480 will my movie have to be small sized?

I'm editing DV video files that, when I look at the specs on the file, says that the dimensions are 720 x 480. Common sense tells me that I shouldn't necessarily have to end up with a DVD that only covers about 1/3rd of my final viewing screen, but perhaps common sense has little to do with it. Much like the lack of it in the US Congress. However, that's what I'm ending up with right now. Is that just the way it is, or are there settings that I can make when importing or exporting that will allow me to fill up my Windows media screen a bit more with the final movie?
I'm using CS5, intel core 2 quad CPU Q6600 2.40GHz 64bit system with 3gb of RAM.

> fill up my Windows media screen
I don't do such, but I think there is an option in media player to expand to full screen instead of the actual resolution... which, of course, means the video will not look as good since it will be somewhat blurry

Importing dvx-200 P2 into 720 x 480

I have video shot on a dvx 200 and I want to import that into my 720 x 480 sequence for TV. When I import the P2 footage into my file, FCP automatically resizes it to fit into 720 wide to accommodate all of the file (1280 x 720).
My question is this: When I enlarge this footage to approximately 120%-133%, will this give me bad image quality and pixelazation? OR does FCP know that this footage is 1280 x 720 and the resize is negligible?
I followed all the tutorials at proapptips for importing and handling P2 footage, but it didn't answer my question.
Thanks in advance!

But you are not enlarging it 120%. You are simply shrinking it less. Have you looked at the motion tab of the clip (double click on it in the timeline to put it in the viewer)?

720 x 480 footage mistakenly put on a 960 x 720 timeline

Hey Guys,
I shot a wedding in SD and imported into FCP. The first clip I always drag to the timeline and FCP always adjusts the timeline to my footage. (I'm real bad at forgetting to go back when I'm shooting SD.) So I cut this whole wedding and it looks great. Does not appear to be stretched or otherwise or I would have noticed right off. Well I end up checking the settings and the settings are set to 960 x 720 - HD Pixel Ratio. So then I copied and pasted the whole timeline into a 720 x 480 timeline yet the footage remained 960 x 720 in the viewer. Here's my question finally, should I just go ahead and finish cutting the show and export it out at SD 720 x 480 or will I run into problems?
If I will run into problems what is the best way to get it adjusted without losing any work, res, etc? Thanks for any assistance on this.

Simply select all the clips in the new sequence timeline (the correct format timeline), right click and select Remove Attributes>Distort.
This will remove the scaling that FCP added to fix your original screwup.

720 x 480? adapter?

Sometimes when i boot up my mac it boots up with my screen being like at
720 x 480, why does it do this?
my screen only goes 720 x 480 when i plug in my adapater to connecto the tv?
so is my mac thinkin that my adapter is plugged in? how can i fix this?
and is there a proper way to 'eject' the adapter from a mac after use?
thanks

Newbie question about video quality in CS3

I'm new to Premiere CS3. I've been using iMovie but wanted to move up to an app with more features and finer grained tuning. However, I'm having trouble getting my imported clips to maintain their quality. Don't know if I've got PrCS3 set up incorrectly or if I don't know enough about video formats.
I'm running Premiere v3.2.0 (374) on a MacBook Pro, 2.16GHz Intel Core 2 Duo, 3GB memory, OSX 10.6.6
Here's my scenario:
I have a video clip with the following specs: .mov, 720 x 480, H.264, 30fps, bitrate 244 (see screen shot below). It was captured from my computer using Snapz Pro X.
I imported the clip into PrCS3 and was surprised the clip preview and composite preview were displayed at less quality than the original (even made sure the quality mode was set to "highest"). The video clip was squeezed a bit and the clean edges of my vector art were jagged. The entire thing seemed out of focus.
I thought the exported video might be better quality. I exported the sequence using the following settings:
But the results were no better (I've actually gotten better results using iMovie HD). Below is the final exported movie.
Any help from the PrCS3 community would be greatly appreciated.
Thanks,

Hi,
capturing from your computer would give you square pixel aspect ratio....and you're using an aspect ratio for SD TV ( ntsc ), so it is stretching ....no longer a perfect "circle" in the paw print...
Your project setting should be made in custom / desktop ( dont use a preset )...and set it for 720x480 square pixels progressive ( no interleaving ), 29.97 fps... the codec choice for rendering when you set up the project could be dealt with later on if this solves your basic problem..
your export would then be the same as your project setting....720x480, progressive, square pixels, 29.97 or 30 fps ...should be good.
one note: h264 is already "compressed" quite a bit....its a "delivery" format...for viewing ...not really meant to be edited...know what I mean ? So you will lose some quality due to that stuff already being compressed...
but your pixel aspect ratio being "fixed" with the above should improve what you see quite a bit.
good luck
