VGA vs S-video - quality differences?

We're thinking of buying a MacMini to connect to our 640x480p plasma screen.
It would be easy for us to connect it via S-video. It'd be a bit of work to get a VGA cable setup, but doable.
Anyone have any experience and opinions on the difference in quality? (We're likely to have some progressive source material from digital TV reception, if that makes a difference.)
Thanks all!

Hello,
Thanks both of you.
You're welcome.
I will look at the cost of running the VGA cable
through the wall, maybe I can pull it through using
one of the existing cables.
Keep in-mind the VGA signals can only span short distances without a signal booster / amplifier. I think the safe range is 10 feet. Beyond that, perhaps 15-feet total before the drop in quality really starts to suffer terribly.
I've never pushed it more than about 10 feet myself. And, I could see minor degradation at that point.
They do have a variety of means to move VGA signals much further. Some are just boosters, others are VGA to Ethernet solutions like:
http://www.networktechinc.com/vga-extender.html
I've been checking out the progressive vs interlaced
issue too - it appears that s-video can only be
interlaced (?).
I do believe you are correct that S-Video is Interlaced.
I assume that the Mac Mini will read a DVD,
de-interlace it since computer monitors are never
interlaced, then re-interlace it when converting to
S-video. Is that right? If so, that must affect the
quality!?
That sounds perfectly logical to me.

Video quality differences (3G DUN vs Road Runner)

I've always used iChat from my RoadRunner connection and accepted the subpar video quality. The other day I was connected to my 3G (HSDPA) phone and browsing from the airport and fired up ichat and did a test video call to one of the apple3utest IDs... the incoming video was near perfect. There were no jaggies and it looked so perfect. i have taken my home router out of the mix and connected my mac directly to the cable modem and still can't get the video to be comparable. the latency on my 3G tethering connection is good (good for tethering), its usually around 250ms (where as my RoadRunner conneciton is under 100ms).. i just dont' understand why this is such a big difference between the two.

Realistically it means changing ISP.
You could try changing the iChat Preferences > Video section > Bandwidth Limit drop down to 500
I presume you have changed the System Preferences > Quicktime > Streaming tab to 1.5Mbps ?

IMovie HD and FCE 4: video quality difference?

Hello,
I imported 20+ hours of video and organized it in FCE4. However, as a novice amateur video artist, I find it far easier to work in the older iMovie HD than FCE4. Do you lose video quality in any way by working in this simpler application?
iMovie HD allows you to save files at "full quality" as a .dv file, but this is still compressed, right?
If I should just suck it up and learn Final Cut in order to not lose video quality, please let me know. Thanks...

The quality for the most part will be the same. Do not try to mix the two applications. They work in different formats. Either work in iMovie or learn FCE, which, if you know how to use it is, is much faster. The more complex the program becomes the faster it will be in comparison to iMovie.

Video quality differences in one movie

I'm new to this whole thing, and wondering if someone has some wisdom for me. I have been shooting video for my first project in 1920x1080p. Then I ordered a new SD card, which couldn't handle high quality video and didn't figure it out until I was in the middle of a shoot! So I had to knock it down to 640x480p. Now I'm trying to make those 2 video qualities work in one video. Would you recommend sizing the 1080p video clips down to a lower res? I'm not sure how I would do that. They also don't match width-wise, so that looks awkward. Any ideas?
Thanks so much!!

Sorry to hear that. Put the 1080p into a sequence created from your 640X480 footage and scale it way down. You won't be happy about it, but at least the resolution will all match.
Or, you could create a widescreen version using 854X480 and put something behind the 640X480 footage rather than have black bars on the sides. Perhaps a scaled up and blurred copy of the same footage.
Just accept the fact that you have now learned your lesson, and that nothing is going to work to keep the quality of the work from suffering. Your best bet is to now do all you can to minimize the damage, not eliminate it.

Dw cs5 FLV video quality difference between web play and local play w/same flv file

When I play a flv locally on my pc with adobe media player.. it looks great.
i build a page, insert it in the page (dw cs5) use auto size detect. upload all..
then go to test it out using FF and the video is not a sharp ( the text titles are especially ratty looking http://www.centroidcnc.com/cncvideo/centroid_digitizing_cs5.html ).
how can this be? its the same file. what am i doing wrong? thanks in advance for any tips.
here is a screen capture of the 480 wide flv playing in adobe media player... reasonable text clarity
and the same file playing in firefox.. with rattly looking text.
is the browser trying to scale it up or something?

Test page looks pretty good but you still have dimension problems.... notice the black bars on the side of the video. Black bars on the sides mean the height is not great enough. Because that version of the player has the controls below the video, you have to ADD that number of pixels to the height.
height: 360, width: 480
so width needs to be video height (360) PLUS height of controls ...15 or 20 or so... may need the trial and error thing again.
The JW Player will play mp4s on the iPhone.
I'd suggest using QuickTime Pro to convert. QT Pro has an excellent "Export for Web" option that exports beautiful video (m4v).
QT will open many file types but if you only have the .flv version, you can use Handbrake to convert to .mov or .mp4:
http://handbrake.fr/
It's free and does a pretty good job. But I still do the final convertion with QT because the finish video comes out so nice.
For example:
http://exploreolympics.com/reports/?p=3499
videos play in iPhone as well as PCs (JW Player with controls over video)
Check for other/newer version of player with controls over video.
Of course JW Player is just one of many media players available. FlowPlayer is another:
http://flowplayer.org/
or get a Flash developer to create one for you... as on the Home page here:
http://www.exploreolympics.com/index.html
This page uses our custom Flash player with fallback to the JW PLayer (using swfobject).
So there are many solutions to your problem, but the reason the text is fuzzy is that the video dimensions are not correct.

Is there a difference in video quality shot on MiniDV tape or HDD ?

Now that the new Macbooks lack a firewire connection, and following on from Steve Jobs comment that there are many HDD camcorders available I just wondered if there is any difference in the quality of the end video between that filmed with a MiniDV camcorder and that on a hard drive based camcorder. I have a Panasonic 3CCD camcorder that is still going strong and I think produces very good footage so I wasn't intending to replace it until it dies, but when I do replace it I want to improve on it rather than take a step backwards or sideways. If hard drive camcorders can produce better quality footage and are not just better for convenience sake I can see the point of dropping the firewire connection.
So could someone clarify this for me, and also maybe tell me what the format choice of the professionals would be?

The answer is that HDD has nothing to do with video quality. It is just another media on which the video is recorded. The selection of media has its own pros & cons independent of the video 'quality'. That said, most tape-based cams record in DV or HDV whereas most HDD based cams record in AVCHD.
Quality is subjective. You can read all about the relative merits of DV, HDV & AVCHD on the net and in this forum. HDV and AVCHD are much more highly compressed than DV but they enable hi-def, 16:9 video.
If you're an average consumer you would be hard pressed to see significant differences between these formats in the finished video other than the obvious 4:3 vs 16:9 aspect ratio difference.
As David said, you will be better off spending time looking for camcorders that have the best lenses, and learning how to shoot top quality video, then worrying about the codec or the media.

MacMini - LG 32" (32LB75) Problem - Poor video quality and now no picture.

Hi there, apologies for the length of this post....
I purchased a mac mini 1.8Ghz with 2Gb RAM yesterday with a wireless keyboard and mouse and hooked it up to my 32" LG 32LB75 using VGA. On startup the display looked ok, I managed to click through the various Leopard initialisations. I bought the machine for use as a front room media player for mainly DivX movies and the occasional bit of music.
Once I had installed the DivX codec I opened a DivX file in Quicktime and selected "full screen mode." As soon as the movie started I became quite disappointed. The picture quality was quite pixelated ("noisy") and certainly not as good as when I play the same movie file from my old dell PC on the same LG tv (the dell PC has a 64Mb PCI radeon 7000 which connects to the tv using the same VGA port as the mac).
Anyway just to give the mac a fair go I thought I would try out some genuine quicktime video samples from the itunes store (this time viewed from front row)....again not brilliant.
So I thought I would investigate the screen resolution to see if I could improve things. It appeared the resolution was set to 1900 by 1200ish I say "ish" because I can't remember exactly. I then attempted to reduce the resolution and eventually I settled on one that looked quite clear with the font size big enough to be easily read. Again I tried the movie and there wasn't much (if any improvement). Whilst changing resolutions the screen would go blank for a few seconds but on one particular setting (can't remember exact numbers) the display went blank and never came back. The tv now just displays "no signal".
I despaired and connected the mac to a 17" Iiyama montior that I use with a PC and it worked ok. However each time I tried to "hot swap" back to the television I would end up with no picture.
I'm really disappointed because everything else about the mac I really like. Particularly the remote for frontrow which is precisely what I wanted it for. The problem is I've spent over £500 and now seem to have a lesser quality picture than I had to begin with (ignoring for the moment that I don't have any picture!!)
Anyway my questions are these, answers to any or all most appreciated.
1) what is the easiest way to get my mini to start displaying on my tv again?
2) what would the optimum resolution be? My television mentions 1366 x 768 in the manual
3) If the mini doesn't offer this resolution in the pick list is it advisable to "force it" using some alternative software (ie 3dexpress.de)?
4) Is the video quality affected by the software player? ie would VLC give better picture with DivX over quicktime/itunes/front row?
5) How likely is it that the video resolution of my new mac mini isn't "as good" as my old dell machine with its PCI graphics card?
6) Finally if I don't get results as good as my existing PC setup, how accomodating are apple with refunds? I bought it from a UK high-street apple store. The back of the receipt mentions a "14 day not satisfied" return policy but then goes on to say something about being "unopened"...which seems a little confusing. Ie how do you know if you're satisfied until you've actually used it?

Hi there
the solution was to remove the various display config files in leopard and then restart the machine, this got my display back on the tv (albeit off centre). To fix the "off centre issue" I used the LG "auto correct" feature from the remote control "menu > screen" options.
The apple support site describes how to remove the affected leopard display files here http://support.apple.com/kb/TS2213?viewlocale=en_US As you will see their resolution consists of 2 main steps, the first one involves starting your machine in safe mode, if this doesn't work then you proceed to the second step where you remove the files using a terminal prompt.
I didn't bother with the first step mainly because I don't think I can start my mac in safe mode since my only keyboard is wireless (bluetooth). So I connected the mac mini to a 17" LCD monitor (which thankfully did display the video signal ok) and removed all the listed files using terminal. I then shut the mac down, swapped the VGA cable back to the LCD tv restarted the mac and it detected the tv and set a resolution that worked. I then very carefully reduced the resolution down to one that was recommended by my tv (1300ish.. x 768ish??).
At this point I was back to having an acceptable signal but still a little off centre. So I used the TV remote, pressed menu, went into screen options and chose "auto correct". Picture then filled the screen perfectly.
The problem seems to be, leopard lists a bunch of resolutions that it believes your tv/display can handle but it would appear that in fact some of these resolutions are not supported by your TV and if you choose one of these your signal disappears and you can't get it back.
I would still say that I'm not 100% convinced with the mac mini's onboard graphics (I have a 1.8GHz version). I'm going to download some HD content and see if that improves things, but certainly my existing DivX collection looked a little sharper and clearer and better coloured using my old dell PC with its radeon PCI card. But the difference in picture quality is outweighed by the convenience of its size and the font row interface. I might tinker with putting Windows Media Center on it one day, perhaps that might improve things.

Poor resolution from mini-vga to s-video adapter

I recently bought a digital projector to watch movies on at home, and am using my 14"iBook as the video source. It works great when using a vga cable. However, i want to run the cables up through the ceiling and down through the wall to keep them out of sight. I had read that S-video was supposed to be a fairly high resolution method of transmitting the signal, and is also a lot slimmer than vga (and thus easier to snake through the walls.) So I bought a mini vga to s-video/ video adapter and when I hook it up to the projector, the image quality is very poor. Is there a setting that needs to be changed on my iBook to get it to display properly, or something else that I'm missing? I bought the adapter used on ebay, so I'm trying to troubleshoot the problem without buying another adapter only to find out that it still doesn't work. Also, I am running screen spanning doctor, but even if I change to mirror mode, it still looks bad.

Thanks for taking the time to reply, John. That was my suspicion. Guess I'll have to drill giant holes to be able to run the VGA cable. Unless of course I could figure out how to remove/re-attach the connector end. Anyone know if this is possible? Or, is it possible to find a 15' long mini vga? It seems that there ought to be someone out there who could make custom cables for unique situations and needs like mine. What I really need is a box that runs off my ibook that has multiple display outputs so that i don't have to pull cords every time I want to switch from my 22" widescreen to my projector.

IPhone 6 Plus video quality is extremely poor when on Facetime and when sharing via text/message

I upgraded to the 6 plus from the 4S. Everyone that I facetime with and send videos to via text/message tells me how incredibly horrible the video quality is....especially in comparison to the way it was before I upgraded from the 4S to the 6Plus. These are people that I have always sent videos to and Facetimed with before, and they all say they can really tell a difference. So frustrating that my three year old iphone 4S is better than the new 6 plus 128gig that I just paid $500 for. We have little ones at home and this is one of the main things we use the phone for....to send vidoes and to Facetime with grandma and grandpa.
I'm on the same carrier (Verizon) that I have always been and have not changed anything. Is there a setting on the phone I can change that will help with this? I love the phone otherwise, but if it can't do this right, I'm going to return it and get my money back.
Can anyone help? Anyone experiencing this???
Thank you.

I have the same issue!! Why isn't there any answers to this problem? I became the laughing stock who owns a $1000 iPhone that can't share videos with family and friends. Please help!!!

How should I best import HD Videos from the new iPad to my mac without loosing video quality?

The new HD video on the new iPad is awesome, but it can eat up a lot of memory in no time. I would like to know what is the most recommended way to export my ipad movies to iLife on my mac without loosing image quality, so i can free up space on my iPad.
If I use iPhoto I notice that the file size of the video from the new iPad is a lot smaller then if I use iMovie to import the same video.
Example: I import a 53 second video from the new iPad to iPhoto and the imported file has a file size of 143 MB in iPhoto. (iphoto save the video as IMG_0048.mov)
I import the same video to iMovie manually and the imported file size is 843 MB in iMovie. BIG DIFFERENCE. (iMovie saves that same video as clip-2012-03-20 16;13;08.mov)
Now to really be confusing: I go to Image Capture program and locate the file manually on my iPad and is has the same name and file size is what is in iPhoto.
So either iMovie is making the File a lot larger when it imports to an event, or the file I'm looking at is actually the iPhoto version that I get because I sync with iPhoto.
The second issue that I have is that now I have 2 videos on my hard drive: one in iPhoto, and one in iMovie for a combined data storage of close to 1 GB.
I would like to be able to import ALL my iPad recording into iPhoto and then delete the video from the device when done.
But if I loose video quality, I'm not happy about that. Secondly, by importing video from my iPad into multiple iLife programs, I'm creating duplicates with sometimes different quality. Any suggestions? is there a setting in iPhoto that can do all this for me?
Robert

Don't use iphoto to deal with movies. it's not really meant for that. use Quicktime or iMovie to work with your videos

Publish+Share signifcantly reduces video quality in Premiere Elements 13

As the title states, whenever I publish and share a video in Premiere Elements 13, the video quality is drastically reduced to an almost unwatchable level compared to the original video This is even the case before any effects are added to the video. If I add the media to the timeline and then directly publish+share before any changes are done, the video quality is still ruined. When I click play full screen in elements, the quality and resolution is exactly where I want it, but once again, when I share the video, it's essentially destroyed.
When I play the newly created video there is giant black space above, below and to the sides of the video (where there is none in the original) and movement in the movie causes the video to grain with black lines.
I have been playing around with settings and researching online for a long time now but I can't seem to find the solution. What I have been doing is going publish+share, ---> Computer, ---> AVI. Then in advanced settings the video codec is selected to DV NTSC, and the basic video settings which are locked in (which I can't change) are set to quality 100, width 720, height 480. The Aspect is D1/DV NTSC (0.9091). I have selected render at maximum depth. I have also tried saving it as MPEG and other video types but the result is the same.
Any help would be greatly appreciated. I understand that I am new and have lots to learn, but it seams so strange to me that the simple process of putting a video in Elements would essentially destroy it. Thanks again.

It was not until Mary Lou Frost posted in your thread today that I realized that I did not see and reply to your questions in post 4 of your thread (dated December 15, 2014). Sorry about that.
If you want to match up the properties of the export file with the properties of the Timeline source media, often you need to direct your attention to
a. Publish+Share/Computer/......and trying to match up the video (especially) and audio compressions of the import with those of the export choice.
b. A frequent cause of a difference between import file size and export file size is the bitrate used by these files. The higher the bitrate, the greater the quality, but
the larger is the file size. So, trying to match import file and export file bitrates is also on the agenda. See the preset's Advanced Button/Video Tab and the settings
there for bitrate. The units for bitrate will be either kbps kilobits per second (also seen as Kbps) or Mbps megabits per second. We can go into that further if necessary.
Premiere Elements allows for the setting of one project preset which should match the properties of the source files. If you have "mixed source files", setting up the
project can become a challenge. The rule of thumb that I typically use involves setting priorities...
1. If videos and stills, I will set for the properties of the video and then size (or let the project size) the still to the frame size of the video
2. If just stills, I try for 1920 x 1080 stills and import them using a DLSR 1080p project preset...that seems to give sharper end product results when doing burn to disc.
Please review and consider and let me know if I have targeted your questions. Any questions please do not hesitate to ask. I try to respond daily to questions, so, if you do not see a timely, response, please send me an Adobe Forum private message asking me "What happened to you?".

Did Apple fix the video quality issue in iMovie '09?

I am a casual video editor and iMovie 08 had the perfect user experience / functionality for what I want to do.
However, the known video quality issue (throwing away interlaced scan lines) made the result unacceptable since I archive our family video on DVDs. I have been forced to use iMovie HD for that reason. I have tried tricks such as converting the original DV files to AIF and deinterlace prior to import into iMovie08 but that did not seem to work either.
So does anyone know if Apple fixed the video quality issue in iMovie '09.
MESSAGE TO APPLE IF YOU ARE LISTENING:
Please fix the video quality in iMovie09 if not already. Yes, the quality is ok for YouTube or Internet video but for those of us who want simple editing to archive our family video we cannot accept poor video quality. Dropping an interlace field effectively halves the vertical resolution. Thank you.

Please explain this in more detail when you say Adaptive Deinterlacer. Are you talking about another program? If so, what program and what are the specific steps.
Also, sounds like you are recommending imovie09. By saying to do the above, are you saying imovie09 still causes you too loose significant quality like imovie08? Are you saying you can use imovie08 or imovie09 with these steps to get high quality video or just imovie09? I guess I just need more specifics on how you do what you are describing and how imovie09 fits into this versus imovie08. I joined this whole discussion trying to figure out if upgrading imovie09 made a difference regarding the whole quality issue. I know it has more features, but I am more concerned about he quality of the video right now. Thanks.

What is the video quality loss going Mac to PC vs Mac to Mac?

Here's the deal, my wife is in the hospital and forced to miss her daughters wedding. I'm trying to sort out an iChat from Louisiana to Texas so she can watch the wedding live and ideally let her daughter see her mom during the ceremony. I've not been able to establish an ichat link into the hospital due to the 'does not reply' demon. So I know its a port issue but this huge hospital is PC only, totally mac ignorant but super willing to put a hot shot PC in my wifes room. My question is what am I giving up by not going mac to mac and giving in on a PC at the receiving end? Are the benefits of the h264 codec only available on the mac to mac solution? Will the video received on the PC be smooth or choppy? What about in a full screen mode? (I guess AIM Trillion is the only option for that)
I'll be transmitting using a G4 Powerbook, 10.4.6, 256mgb ram. iChat 3. I'll be shooting with a digital video camera with firewire output. I've tested that, it all works fine in recent chats with other macs. I'll be sending over Earthlink DSL line, 256kbps up/3mgbs download. The Hospitals bandwidth is T-1 huge so not a problem. I'm just afraid I'm not going to get them to sort out the issues for a mac and will have to give in to a PC.
Appreciate your thoughts. j

Hi octoguy,
iChat makes hardware and connection speed checks as it starts up.
This gives you the framerate and bit rate duirng a call.
Lets say that your processor gives your iChat 15 fps
This will be the rate that you will then see to a another Mac.
The same computer is likely to get 10 frames per sec to a PC.
This is some part due to the PC putting a fair amout of effort into producing a clear detailed pic.
On some PCs this setting for the video pic is so high that the audio will drop out completely.
The cure is to bring the PC preview to the front (tabs)
Then click on the small icon that appears to the right and adjusting the slider that appears to the left.
This will incease the frame rate and bit rate from the PC. It makes the video look smoother although the actual quality has gone down (you may not be able to judge this quality difference by eye)
As general rule you will get about 2/3rds of the normal Mac to Mac framerate shown in the Connection Doctor. It also seems to take about 50% more Connection speed to get the same quality video.
So Mac to Mac min is 100Kbps where as Mac to PC will need about 150kbps.
The quality drop from 15 frames a sec to 10 frames a sec does make the video generally more blocky but does also depend a fair bit on the processor power of the PC and the camera used.
I know that sounds a little vague but there are really many variables that can be a factor.

What video format is best for video quality?

Would anyone care to comment on what video format is recommended to achieve the best video quality in Encore when burning to a 25 GB Blu-ray disc? I have the choice of saving my HD video that will be imported into Premier Pro CS4 (and then sent to Encore CS4) in .mp4, .mt2s or .ts and I'm not sure which one will give me the best results. Thanks in advance for the insight!
Ken

does that mean that one is not necessarily "better" than the other?
That is correct.
Now, some feel that with the MP4 H.264 that there are differences between the Apple, the Lead and the MainConcept H.264. Each supplier has a "camp of followers."

Mac Mini Video Quality

Can anyone tell me how the Video Quality of the output to a HDTV if I buy the correct cables to connect to this HDTV? I am looking a "media server" and I would like to use a Mac Mini rather than an Apple TV because I can do more with the Mini (surf internet, use as DVR etc..), plus I would be able to play DVD files without having to convert them to .H264 format that would take eons.... I currently have a iBook G4 and used the S-Video adapter to connect to the HDTV set I have, and the Video quality is about par with VHS, even on DVD content (I'm not even going to think what iTMS downloaded content would look like). Thanks for your help.

Just to be clear, is this the model you have?
