Mpeg question

ok first off i know how to encode and i encode by using nero recode 2 and dvd decrypter. nero recode encodes to mpeg and not the h.264 which i am ok with. Videora wont work for me and i cant be bothered ot spend time figuring it out when nero works fine.
But my question is, i had been encoding my video's at 320x240 (i thought nero was h.264 for the longest time and went by those standards) and was fine with that. but yesterday i wanted to try out 480x480 and encoded a small video i had. I encoded just fine and i did it the same way i normally would. But when i transfered it to my ipod it had huge black borders (like if it was widescreen but on the left and right sides to. basically the movie was inside a black box if that makes sense) Letterboxing was turned off (since it is a fullscreen clip. But is there a way to get rid of the "black box" effect?
Now this clip i downloaded from the internet and originally encoded to 320x240 then tried reencoding it to 480x480 if that matters? I am not to sure if that could be the reason or not.

You're trying to turn a rectangle into a square. Something's going to change shape.
Do some math and you'll see that a source file of 320 (width) and 240 (height) should become 480X360 when enlarged.

Cs4 mpeg question

I've been editing some mpg2 files off of dvds with no problems. The last 2 files i've ripped however have been ripped successfully. I can view them in media players and everything works fine, the timing is perfect. Then when i import the files into premiere pro and it conforms the video they're listed as only 21 frames per second and the audio and video is off. I've done this succesfully several times in the past. Why is it messing up now? How can i fix these videos? Any help is much appreciated. Thanks!

in premeire pro when i click file - get properties for - file this is what comes up on the video file:
Type: MPEG Movie
File Size: 5.7 GB
Image Size: 720 x 480
Pixel Depth: 32
Frame Rate: 29.97
Source Audio Format: 48000 Hz - compressed - 6 channels
Project Audio Format: 48000 Hz - 32 bit floating point - 6 channels
Total Duration: 01;55;53;29
Average Data Rate: 860 KB / second
Pixel Aspect Ratio: 1.2121
After i import it this is what it says:
Type: MPEG Movie
File Size: 5.7 GB
Image Size: 720 x 480
Pixel Depth: 32
Frame Rate: 21.80
Source Audio Format: 48000 Hz - compressed - 6 channels

Total Duration: 02;07;31;16
Average Data Rate: 781 KB / second

so if i'm reading this right, the framerate and the total length of the video is off. any ideas on how i can correct this? i don't have cs5, just cs4.

Missing Audio mixed bunch 32khz and 48khz

Hello,
I have an audio problem as well. I have been reading the MPEG questions but so far I haven't found what I am looking far.
I'm relatively new to editing. I edited a video on Adobe Premier Pro CS3. The volume for all of the clips was audible in Premier. Now when I transferredd to DVD, I can't hear some of the audio. Specifically, I can not hear the parts where I used the on camera mic. The hz for that was 32 and the hz for everything else was 48. Can anyone tell me if I can fix this problem without having to reshoot the footage?
I am working in Windows XP.
The original file is an avi. I set the audio preset to 48hz. I encoded as MPEG2 SVCD and then I burned a DVD-R using Nero. When I was burning on Nero I believe the audio setting in Nero was 44.1khz. I need this to be played on TVs. Can anyone help? Everything was going pretty well up until now.
Thank you
Carla

Do you hear sound when you play the MPEG2 SVCD file on your hard drive?
Cheers

Mpeg-2 flags, dvdsp, and 23.976 video question

just got through this thread:
http://discussions.apple.com/thread.jspa?messageID=9786956
and have a remaining question. i looked at the m2v file in
mpeg streamclip and i see:
Video Tracks:
224 MPEG-2, 720 × 480, 4:3, 23.976 fps, 7.70 Mbps, upper field first
is the 'upper field first' just a flag to tell how to deal with
this file? or is it stating that the file is interlaced with the
upper field first?
the intent is to make a progressive dvd at 23.976. the original
material is film, captured and edited at 23.976, progressive. the
material was captured off of an old projector, a frame at a time,
with a digital still camera, so the original has no interlacing
or fields. this went to make an image sequence, which was rendered
to a qt movie at 23.976, also progressive, no fields. it was then
output through compressor to the m2v file which produced the mpeg
streamclip stream info dialog quoted above.
thanks,
BabaG

Yes, it's just a flag.

Question about "RE-COMPRESSION" of mpeg 4 files

First off this is a great forum. It has answered many questions. This is my first post.
This is my workflow.
1. I have a massive library of Betacam tapes that I am archiving ( over 2000) average length 45 minutes)
2. I capture them from a betacam deck, thru a canopus adcvc 110, at SD, No problems.
3. I wind up with media files that are like 15 gigs. I have over 40 terabytes of external storage, I use firewire 800 (so far, so good)
4. I then take the media files, drag them to the timeline, edit etc, add graphics from motion etc
5. I then simply play the timeline via firewire to a dv, video deck, and send the tape to the tv station, they closed caption it and it hits the air
(so life is great, this works perfect)
Here comes the question
1. After having done that, I use the "send to compressor" function, to generate an mpeg 4 file, which instead of 12 gigs is like less than one, it looks great.
2. This file is then uploaded to an ftp site, given a description, and then put on the website for viewing or purchase.
3, since I have like 2000 tapes, do the math, if each one takes 12 gigs....lots of drives.
4. Most tapes are NOT edited for television broadcast, I just find a good in and out point for a fade, compress it, shoot it to ftp and im done.
5. Recently I have begun deleting the 12 gig files, sine I have the messages in mpeg 4...to avoud buying several petabytes of storge.
SOOOO
After all that, here is my question.
If I want to edit a program that I have in the archive, that the decision has been made to broadcsat for some reason, If I drag the MPEG$ file onto the timeline, edit it from a 50 minute down to a 28:30, drop in green screen cut aways, grapics, lower thirds animated transitions between clips, titles, etc...
Render it.
THEN play it directly from the timeline via firewire to the mini dv deck...
How much quality will I lose on the base video, which is mpeg 4, as compared to the 12 gig media file?
Does it "re- compress" in some way?
should I just suck it up and pay for storage for the 12 gig files that probably will never use for broadcast?
or can I use an MPEG 4 file as my "main video" and not come out looking like an amature moron?
Does any of that make sense? or is it TMI from an idiot?
I come from the analoge days, D-3's and D-5's, grass valley 200 switcher, pinnacle dve's, 18 Ikegamis shooting NFL football. Betacams, D-1's, sattelite uplinks. all in good old NTSC 525...
So bear with an old man.
Any assistance would be great.
Can I edit using an MPEG4 file and not get burned?
Be well all.

You probably won't have a huge loss in quality-- as you say yourself, the MPEG4 looks pretty good for it's file size. I won't get into a debate about whether or not it's the best option for archival, that's another thread.
But as long as you're editing in FCP (7), you'll want to convert it to something else before importing. ProRes is a pretty standard choice. Otherwise it'll be nothing but pain. You can still archive in MPEG-4, but for those that you pull from the archive to re-broadcast, recompress them to ProRes.

Exporting to a mpeg file, or a DVD format ??? questions around this:)

Hi friends
May I ask a silly question?
I wonder, when i have finished editing the movie, audio, effects, and all of that. When I am VERY satisfied with the result ( do you know the feeling )
OK, everything is on my timeline, and I press Ctrl + M. I choose MPEG2, and I get a file that I put on my desktop. From my desktop I burn it with Windows DVD Maker, choosing to make a dvd in this program.
Here is my question: Do I have to use another then PRpro for making an DVD formated DVD disk?
Is it the same to burn a DVD file on a plate, then burn a DVD formated plate?
And then, why cant prememiere do this?
I use the Que in media encoder, but that does not make any different...
Help me to understand this, please.
Best regards from Norway
Stig

Thanks for getting back to me so fast, and knowing exactly what I ask for .
So what I have learned is: Windows DVD maker is a program that does the same thing as encore, but of course a smaller program.I have made menues in encore, but I did not know that it also made proper DVD files. Is it easyer from DVDmaker (if no chapter)? (it took me about 6-7 hours burning in W DVDmaker for 1 hours movie)
One more thing, please. I also try to burn from PRpro using the "Match the sequens setting" button. ( I use an AVCHD 1080i setting, square pixel, Frame size: 1920 x 1080) Is this compatible with DVD burning?
Is it right to choose this setting when burning? The reason I choose "Match the sequens setting", is because I get a larger file (twice as big), then in MPEG mode. I am then thinking... bigger file, better picture quality on TV. (?)
When I sit here now, I try to make dynemic link to encore. It is ok, but Encore tells me that the Transcode settings are 720X 480 (in new project window in startup encore). This is not an HD setting, and is not an 1920 x 1080 like I have in premiere Pro.
Hope you will help me again.
Best regards
Stig

Reposting a question that didn't get answered in previous post: best preset to save mpeg project?

So it took me a week or so to get to try out the answer I'd gotten, & I couldn't get that answer to work, and then my follow-up question didn't get answered, which makes me wonder if threads & discussions kinda die if they're not kept up? (I'm not very experienced in how these forums work, apologies). In case that is the case, I'm starting this new one, but refer you back to the old (unfinished) one. Just scroll down to the last few exchanges to get the gist of it. Thanks . . . Mark
the previous discussion:   http://forums.adobe.com/message/4663058

Steve--Sorry if this approach wasn't the best--as I said, I'm not well-versed in forum protocol-- but I did post it last week to the end of that discussion as you recommended but didn't get a response, so I wasn't sure how best to proceed from there. Anyway, hopefully this works ok for you. Here's a copy of the relevant exchange. I'd written: "I'm using a Lumix DMC-ZS7 which, on the small test I did, was set to 640x480 & is a MOV file, and while the "correct" preset choice isn't there, there is probably a best choice among the many choices that are there, and that is my question--which should I choose for this particular clip at this resolution? Both for quality & cross-platform usability? The camera also has AVCHD Lite", whose specs read: -- SH: 17Mbps /H:13Mbps /L:9Mbps ) / 30fps (Motion JPEG)   1280x720 pixels, NTSC Mode: NTSC model: 60p(CCD output is 30p)."
You wrote back: "Shoot in AVCHD Lite and, when you set up your Premiere Elements project, select the project settings for AVCHD Lite and you should get much better results.
Obviously, your video is not going to look perfect at full screen on a computer no matter what output settings you use. Your monitor is likely larger than 1280x720. But you should then be able to output using Share/Disc/WMV setting your output for 1280x720 using the Advanced settings."
And here's my follow-up, & hopefully final, question, from last week:
"Hi Steve-- I just now had time to try out your recommendation--and I will in the future shoot in AVCHD Lite--but for the existing mpeg stuff--I could not find the settings you recommended. ("Obviously, your video is not going to look perfect at full screen on a computer no matter what output settings you use. Your monitor is likely larger than 1280x720. But you should then be able to output using Share/Disc/WMV setting your output for 1280x720 using the Advanced settings.") Firstly, I took this to be your answer to my question of how best to save mpegs, not AVCHD Lite, am I right there? Under Share/Disc I couldn't find any WMV settings whatsoever in any of the choices, nor was there any Advanced option. Under Share/Computer there is the Advanced option--but again, I couldn't find a WMV setting.   I did find 1280x720 under the Share/Computer/mpeg presets, as a couple HD 720 options & three HDTV 720 options. If indeed one of those is the best choice--which one? Or is your original suggestion still the one, with its non-obvious location to be revealed? (by the way, I've got Premiere v10.0).
Question 2-- when I do start using the AVCHD lite, is there any one preset you can advise as the best one to use?
Thanks again--Mark

Some questions while using JMF play mpeg-1 stream media?

I use Helix server to provide unicast, and use JMF to play the stream media. But the JMF only play the audio stream transferred by rtp. I have used video palyer�s getVisualComponent() method to get Visual component and added it into the frame. But I get a pink screen. So I think some thing wrong with the video player.
Who can give me an answer?
1. Whether JMF can play mpeg-1 video stream media?( Audio can be heard. Video stream comes to my computer but can�t be displayed.)
2. Which method it should use to synchronize video stream and audio stream?
BTW: In JMF, when the RTSP player�s start() method is invoked, the player creates players by the stream�s track numbers. Video stream and audio stream have different players.

Try posting your question under the Java Media Framework forum instead.
You'll get much better responses if you ask the right people !

MPEG to MOV question FCE

First, let me thank the forum members who have offered their help and expertise during the learning curve time for me.
The task: I am taking bits of footage from DVDs that I own and converting them to MPEG. The footage will be used in FCE as part of a family DVD I am putting together.
The questions:
Will FCE allow me to import MPEG?
If not, will I have to convert to MOV, and what program should I use for this conversion?
The quality looks great when I play the MPEG clips in WMP, but will I lose quality during a conversion?
Thank you
-Mike

In the Buy Now area select your country.
That directs you to your Apple Store.
Select Mac Software.
Select Web and Video.
Select the Mpeg 2 component, buy and download.
It says Quicktime 6 but also handles 7.
Be aware that there is also a Windows version as well. That's why there are two in the list.
Double check you purchase the correct one.

File format question h264 /Blurry MPEG 4 output

"The codec with the best quality to size ratio is H264" was suggested for me to use when making web movies. This may be a stupid question, but is tehre any other file format (other then MPEG 4) that will play on an iPod and other digital media players. My Mpeg4 looks blurry and I really don't know why. I input h264 video into iMovie/ FC Express and the edit. When I export to MPEG 4 the video is blurry. I am only going down in physical size so pixelation is not the issue..(i think).

You see aac and h.264 are not editing formats in the FCP world. Easiest is to convert them first. It's very easy. Go get a copy of MPEGStreamclip and convert them to something useable, like ProRes LT. Then just import them, and drop one into a timeline and let the timeline adjust to the footage. You do not have to setup one of the easy settings in order to work.

Question Regarding Audio in MPEG-2 Compression

Hi,
I have recently been on holiday and wish to compress some stock footage which is taking up ridiculous amounts of space on my Mac. Not only will it be saving me precious HDD space, but I wish to put it on DVD at a later date too and know that MPEG 2 is the standard for SD DVDs.
My problem is with the audio when compressing for MPEG-2. I Understand that both have to be compressed separately so I'm converting the video with a dolby soundtrack, but how do I join them again?
Alternatively, theres the option of checking a box so the audio is multiplexed however the end result always seems to be a file thats unreadable by all applications on my Mac (All software is up to date and I own the entire FCP studio)?
It's a slightly 'Noobish' question I guess, and I'm thinking I'm in the wrong section altogether now oops and maybe I should be looking up how to use DVD Studio Pro?
But any help/ Guidance would be great for an amateur like myself who's just starting out with trying to get his head around the Pro Suites.
Thanks in Advance.

Hi:
My problem is with the audio when compressing for MPEG-2. I Understand that both have to be compressed separately so I'm converting the video with a dolby soundtrack, but how do I join them again?
You don't need to join them again ! You must import both audio and video files in DVDSP and place them in the same track.
You must choose the right DVD enoding preset depending on your footage lenght in minutes and encode your video as MPEG2 and your audio to Dolby 2 (AC3). Giving both files same name (i.e. movie1.mpg & movie1.ac3) will help you to organize your assets in DVDSP.
Visit the DVDSP forum and use the Search feature. You'll find a lot of good info in previous posts.
Hope that helps !

MPEG Stream Clip questions

How do you use this converter.......I dropped a mpeg in there but don't see how to convert it. It looks like it basically acts as a player......where are the options to convert and not just play, fast forward and rewind? PC person converting over to the mac world, sorry for the stupid question...
Jay

Hi -
As you found out, just drag the file in, then go the File menu and choose the format you want to export (convert) the file to -

Import mpeg-1 question

I am THINKING that I am reading that neither imovie 8 nor FCE 4 can directly import an mpeg-1 file (which is what my Sony camera records). If I take it through Mpeg streamclip does it degrade the video? If so is there any way I can get it into these programs without doing damage? Even to just string some of them together?

Your material was already degraded when it was recorded to the extremely compressed mpeg1 format.
It is not likely to be much worse for the conversion to DV/NTSC (or DV/PAL).
You are right to be concerned with the quality of material you bring into the editing program and the best way to ensure highest quality is to use a camera that records a format that needs no conversion. mini-DV tape based cameras are a good place to start. Everything that records on hard drives or DVDs needs to be transcoded to edit in FCE.
Good luck.

MPEG Muxed Question

Hi,
I am editing a video for a non-profit, and they've received some footage of a story about their organization on the evening news. They were given a DVD with a movie file that when I get info about it says its an "MPEG Muxed" file. Using Quicktime Pro I've tried to export the video into a format usable for Final Cut Pro, but when exporting Quicktime won't allow me to check the box necessary to include Audio in the export. I'm assuming this is because its Muxed, but when i export anyways I get no audio. Does anyone know how to demux a file like this? or know a work around for getting this video to work in final cut? Thanks.

MPEG Streamclip (free) and the $20 Apple MPEG-2 Playback Component should be able to convert with audio.

Exporting to mpeg-2 question

My friend gave me a bunch of 720x480 mpeg clips from a music festival and asked me to edit them together.
When I play the raw files on my standard TV they fit perfectly...
But when I export the edited files as mpeg-2 in the same resolution...they are scaled down and dont fit the TV.
I know this will seem like fairly basic stuff, but I've searched and can't find an answer.
Any help would be greatly appreciated!

Maybe you could be a little more specific or show us a picture. what do you mean by "shrinks"
is it smaller in every direction or just squeezed letterbox? it must be a sequence or encoder setting for the resolution or aspect ratio.
