High quality media vs low quality media

Hi,
I have a probably somewhat naive question about DVD media. I'm sure that there is a whole range of quality amongst the various suppliers. How does "high" quality distinguish itself from "low" quality (other than price, of course)? In other words, does a high quality DVD-R simply produce fewer coasters? Or will it also have a longer "shelve-life"? Are there cases where a low quality DVD will burn fine but will then contain errors, or can I assume that once the burn was successful and verified, I'll have a reliable disk, no matter who the supplier was?
I'm asking this because I could live fine with a cheaper DVD and higher rate of coasters, as long as the disk is reliable once it is burned.
Thanks for any insights you may have on this.

Export Media Question re H.264 PAL DV Widescreen High Quality

Using Premiere Pro CS4.
Why is the movie that I export being squashed into the 4:3 (tall and skinny) syndrome when I export using the following settings and view in Quicktime Player 7.6?
I captured the video straight from my video camera as DV AVI PAL 720 x 576 (1.4587).
I export the media as follows:
Format: H.264
Preset: PAL DV Widescreen High Quality
Summary - PAL, 720 x 576, 25FPS
It seems to be only happening with my .mp4 exports!? i.e. the 16:9 ratio is perfect when I export to Microsoft AVI.
The really bizarre thing is I uploaded a squashed looking video to my Vimeo account and it displayed correctly (16:9) after processing! Why then doesn't it play correctly in Quicktime Player?
Am I missing something in the Quicktime Player settings?
Please help!

Here is how to correct this issue in the QT file permanently so it opens in a QT player correctly .
Open your mov in QT Pro
Show Movie Properties (Ctrl-J)
Click on Video Track
Click on Visual Settings Tab
Un check the Preserve Aspect Ratio box
(Here is where you now need to do some math to change the 4x3 to 16:9 ratio)
Divide the Vertical Pixel Dimension by 1.78 and enter the result in the Vert Dimension box
Ensure the Preserve Aspect Ratio box is UNCHECKED
Hit Tab key and notice the image in the QT window change.
In the QT Window Menu - File>Save (Save is important!)
Heres an example:
QT movie Original is 320x240
Divide 240 x1.78 ( ie. 240/1.78=134)
Bingo!

Do High Quality Media Render files keep piling up?

I just noticed that a file I worked on over time, through a number or revisions, had Render: High Quality Media files from all kind of dates. It added up to 15GB. I deleted it and re-rendered and it came to 1 GB. Is it possible that FCPX isn't replacing any old renders and just gobbling up disk space? Is there a setting I'm missing?

My suspicion is that it may have something to do with your scratch disk filepath. What is your scratch disk filepath - drive name, everything...

Can I move the High Quality Media folder in Finder?

When importing files for a large project (music festival, 15+ hours of footage) I left the high quality media transcoding option ticked and, with only half the footage in, I have a nearly full disc (external 1TB Lacie little big disc).
I don't intend to use these files until final rendering (I use proxy editing) so can I temporarily move this folder/files off the disc in Finder until I'm ready to use them or will this upset FCP X? Is there a better way to do it within FCP?

If you're going to edit entirely in proxy, there's no point of making optimized media. When you're done editing, switch to original playback. When you export your master file from FCP, it will export ProRes generated from the original media, which is the same as optimizing it. The only factor is if you're going to do color correction and effects in FCP, then you will want to do that on optimized media if you can rather than proxy media. There is no way around that. You will then need the ProRes files at that stage, not when you export.

How can I replace one low quality source with another high quality one ?

Am I really this dumb or is it really this hard ?
I have one timeline / project / edit that essentially references one long source clip / event / file.
I have a newer higher quality transcoded version of the same source and want to replace the original lower quality version and end up with the same edited result just with better quality images !?
It's the same frame rate and image dimensions but "relink" tells me the new file is not "similar" enough and won't do it !
Why is this so hard ? Is there a way to export a good old fashioned edl and then just reconform using the new source ?
What if I wanted to to replace low res offline footage with finished colour-corrected material and output a finished master - would that be this clueless as well ?
Please let me know the problem is between the chair and the keyboard - not between the hard disk and the power cord !

Guessing that when you created the higher quality media, it was done outside of FCP and probably changed some important metadata that the app is looking for. Or perhaps there is a difference between the original audio and the new audio.
Anyway, Luis' advice about the replace edit seems like the easiest solution.

The usual way to do offline online is within FCP – creating the proxies and then using Preferences to switch back to and from.
If you sent it out for grading, the Relink should work fine. If you haven't seen this kb doc, it's worth reviewing.

How to edit and make a high quality swf a low quality one

How to edit and make a high quality swf a low quality one. how do you do this in adobe flash cs5? The file i edited is entirely too large

click file/publish settings/html and use the quality settings dropdown.
if that doesn't lead to satisfactory file size, you may need to check the properties of each bitmap in the library to see if it's set to over-ride the global settings.

All my pdf files can be printed in low quality on my Brother printer but can't print in high quality in the printer menu.

My problem is that all my pdf files can be printed when I choose "low quality printing" in my Brother printer menu but cannot be printed in "high quality". When trying to print in high quality, the documents load in the printer tray and it says 1 document then disappears and 0 document printing is showing. I have some pdf files that I want to print in color in high quality and black and white but I'm unable to do so. It only prints in low quality for both color and black and white.

How do I create a High Quality Image with a low file size???

Dear All,
I am creating an invitation in Illustrator which I then place into photshop to create a JPEG. I want to create a high quality JPEG version of it but with a low file size because I am emailing the invitation. Am I correct in placing the image into photshop or should I export it from Illustrator.
The image is built of of vectors and one JPEG but they are not high in quality.
Can anyone help me please
Thanks
Ben

The image is built of of vectors and one JPEG but they are not high in quality.
For this type of image you would probably be better choosing GIF format (now known for some reason as 'Compuserve GIF'). Taking the number of "colors' down untl it still looks high quality, and anti-aliasing is preserved.

How to change the low quality to high quality in iPhone 5c?

Hi everyone, I need help about this uploading a video on Facebook. Here's the story, I uploaded a video last friday (april25,2014) and I have to choose what quality the video should be, and I chose the low quality (for low space *new on iphone*) but, i think I was wrong on choosing the low quality over high quality. I watched the video from my Camera Roll and it's on high quality, but on facebook it was a low quality video. Now, does anyone could help me to change it to high quality from low quality?

Importing high quality video through a lower-quality camera

(Final Cut 5 in a G5, 10.5.8)
The camcorder I'm using to shoot video for my Final Cut projects is a Panasonic PV-GS400, a good 3-chip mini-DV camcorder that shoots high-quality DV (original price $1500).
I would prefer not to use this camera to play the video into Final Cut, to save wear and tear on its tape drive (with tape, of course, one hour of recorded video takes one hour to play into Final Cut).
I have an inexpensive little Canon Elura 100 Mini-DV camcorder (original price $400) that could be used to play the tapes from the Panasonic into Final Cut, but if I did that, would the higher quality of the Panasonic's video be degraded to the lower level of the Canon's video when passing through?
To put it another way, can a Mini-DV tape with high quality video on it be imported through a relatively low-quality camera into Final Cut and still retain its high quality?
Thanks for any help.
Tom

Thanks much, guys. Yes, I'm using firewire. Glad to hear there's no loss of quality when the video is strained through a lesser camcorder on its way into Final Cut.
So now I'll go ahead and use the little Canon Elura as my playback/ingest camera with no worries.
I appreciate the help!
Tom

When I move high quality clips into my timeline in Final Cut Express HD, they look and export low quality. I have tried converting the clips and de-interlacing them, but they always look the same, What is the problem? Thanks so much.

You should check that the Project settings match the clip settings before editing them to the Timeline.
Only newly created Projects will change not existing ones by adjusting the Project settings.
If, for example, you have a Project set to NTSC DV you can only end up in trouble if the clips are PAL 1920 x 1080i.

How to Export a WMV file in High Quality but low MB?

How to Export a WMV file in High Quality but low MB?

I'm really afraid you are the only person who can answer that.
ANY compression is totally relative: what do you think is small? What do you define as high quality?
I can get a 5 minute wmv file at just under 100mb that I find acceptable for browser downloads. You might think that's too big. I don't.
Trial and error is the only way. Personally, I've set up a compressor preset to crunch my wmv files. While it's doing it's thing, I can do something else.

Low quality DVD outcome.. need help for high quality result ASAP!

Hi every 1,
(This is my first post, as I only got my iMac 2 weeks ago.. so please be gentle with me :P )
I have just been asked to turn a Microsoft powerpoint (PPT) into a DVD for "induction training video" purposes with voice overs and backing music. I have a professional music studio so providing high quality audio is fine, but trying to turn the power point into a high quality DVD file is my problem. This powerpoint has timing transitions (fade ins etc) for the timing of voice gaps. When using Microsoft PPT, you can turn the PPT into a Quicktime file which I was going to drop into iMoive then add the music and voiceovers.. this is when my problems started. Microsofts powerpoint doesn't add the transtiions and effect into render Quicktime movie, so I thought as my new iMac has iWork (KEYNOTE) I'd give it a try and to my surprise it all worked and the final mpeg4 quicktime movie result work great _when you look at it on the MAC_.
1) Problem
I then exported the file into iMovie and then my first Problem arose.... (grr). I movie lost it's sharpness and the images started to have pixelation.. that seemed to pulse in 1 seconds gaps.
I hope this was just an issue with the iMovie preview window and thought once I put it into iDVD and burnt it... the final result may be fine.. but I was wrong and the quality was crap... with the pixelation still there.
2) Problem
The other problem that came up was the about 25% of the edge of the total screen was cutoff. When i did the original file, I choose 4:3 ratio, and watched it on this..so where did the image size go wrong.. I also choose the "high quality" Quicktime file, but didn't go into the settings in the iMovie in the export section (which I should off), but after check the compression type was H.264.. and I also didn't change any settings in the 'export file' section in KEYNOTE.. this is where I think I must have gone wrong..
So in closing. my questions is:
-What's the best way to turn a PPT into a _high quality file_ so it looks professional once it goes through iMovie and iDVD.. or
- Should I just redo the whole production using iMovie ( by re doing all the work eg wording, transistion inside iMovie seems like a lot of extra word ) and so not use the PPT at all... and if I do this, then
- What's sizes, and ratio and compressions should I use for 4:3 ratio TV purpose (eg. whats size should a background image be that I do inside Photoshop, so I can put the transition wording over the top, so I see it on the TV screen and the edge doesn't get cutoff etc.?
I was very impressed with Keynote and would be happy to use this for most of the production.. but am I banging my head againist a wall...re fixing quality problems when exporting files into... can someone shed some light on this for me?
Sorry this is such a big post.. but I thought if I gave you most of the background you would have to ask so many questions.
Look forward to any help any 1 can provide..
Michael

Matti,
Thx so much for your help.. it's really appreciated. This is by far the best result quality wise, (but I really am a perfectionist and personally are still not overall happy with the final product) but if my client is happy.. then I will continue down this track for this job.
ie Create TIFF;'s>Quicktime PRO>iMovie (transistions)>iDvd
You've been a great help and I hope it good enough for the client.
I find the images and wording lose their sharpness only after being imported into iMoive. I could still be probably enhance the quality level of the TIFF's once more, as I did the test slides in Keynote, then exported the 5 slides a individual as TIFFS out of Keynote, then imported the into QuickTime Pro as you suggested then followed your instructions all the way to the final burning of the CD. I also tried doing this in Photoshop using your suggestion of 720x576 images (for PAL) .. pixel aspect ratio to ~1.094 so you can see the correct proportions for 4:3 video output. When creating the new slide in Photoshop there were a few extra settings other than the ones you gave me... _so I would real appreciate what every setting should be when creating the NEW TIFF file in Photoshop for PAL 4:3._ I noticed when I did this the image crispness on the fonts was shithouse pixelated and shadows, even while looking at it from inside Photoshop )
As I tried mutliple ways of importing into iMovie (yours being the best suggestion) I really believe when dragging a TIFF or movie turns to blur on the way into iMoive. You can see the image is blurred from that point on.... _do I need to buy final cut pro or express to get a better image quality result?_
I also tried iMoive7, which I found was great to use video editing wise, but Apples has definitely stuffed up there by not give users a 'time line' to work with in the Audio section... but everything else in the video area was great to use.., but in my situation trying to line up the narration to slide, while having also background music is now impossible sadly.
Also I really like the 3D transitions in KEYNOTE, plus iMovie 7.. do you know if there are available for HD6 or if there's a 3rd party company that has smilar versions
Thx again,
sycosingo

What techniques for storing high quality & low size songs in iTunes

I use iTunes with an 80gb ipod for music on my Home Theater system. For this, I'd like to use Apple Lossless files (higher quality & I can afford the big files).
For the family iPods, I'd like to use 320kbps (good enough for iPods & small file size).
What are good techniques for keeping both size files on my iMac? I'd like this to be as simple as possible.

This is often asked and there is not any simple technique. The choices are to either keep two separate libraries (that would be my preference), or to keep separate playlists within a single library.
Note that once you get set up, any new files you add to the library will have to be manually handled to make sure that the 320 version gets added to the additional library/playlists.

DV AVI in high quality problem

Has anyone had this problem, or know of a solution?
I'm using QT Pro 7.1.3 / WinXP Pro.
I can play back low quality DV/DVCPRO - NTSC .avi files perfectly, but when I switch to high-quality, the player window remains the same size, but the image is cropped to the top left quarter of the window - the rest is filled with black. This top quarter displays in high quality, and plays smoothly, but is only 1/4 of the image.
If I also check off Single Field, the whole left side of the window is then displayed, but only a single field.
The files play back beautifully in Windows Media Player, but I'd prefer to use Quicktime player.
Any hints??
Dual Athlon Windows XP Pro

I am having the same issue, It plays ok on my Mac Pro, but when I play it on my XP pro machine, it only plays in the top left quarter of play window.
Have seen this question in oter threads here, but they remain un-answered. Hope someone can help with this issue, as it is quite annoying!
