Maintaining video quality.

The quality of the vids I'm processing with IMovie for YouTube seem to be degraded from the orginal.
The vids are in mpeg-4 format to start off with. I import them into IM and add some introduction screens and crossfades then Share/YouTube. Should I follow some other methodology to maintain quality?

How to maintain video quality after resizing?

I have a 640 x 360 px video that I want to resize to fit a 480 x 270 px flash movie. When I resize the video to fit the smaller stage the image quality suffers, it looks like low res. When I crop to fit, it looks fine. Is there a way to maintain image quality when reducing size?

I have nothing on this computer aside from Adobe and a few other audio apps. This is a dual Xeon 6GB system. I work in IT and am MS certified. I do not think it is the system. I am using AE CS6. =A0Keyboard is set to its defaults. I do not touch the keyboard mappings. The effect brings the clip down to 10% or so. How should it be resized? SHift - click and drag works in all of my apps like Photoshop, so it isnt the kb or the system. Is that the way it is supposed to be done in AE? If you have AE, are you able to try this to see what I mean?

Why is the video quality so bad on the recent download helper upgrade

I use the download helper add on on a daily basis and the video quality up till yesterday was crystal clear. but then yesterday there was an automatic update to the latest version and since then the video quality is total crap. nothing but annoying pixilation. why is this happening and how do i fix it or how do i go back to running the old version if it cant be fixed.

Why is my video quality so bad?

So I have this video which is just over 1GB and it's just under 6 mins, so surely the quality should be better than this? It was shot in 1080p with a Canon 7D. I have however scaled it up 150% using the scaling effect in Premiere Pro. Should I scale it a different way?

The AE (Detail preserving upscale effect) worked perfectly. It's actually very effective at maintaining the quality even when scaled up 150%

Chat video quality...

Has anyone been able to video chat with two or three people and maintain a decent video quality? When I try to video chat with two people the quality drops considerably, and I'm wondering if it's a bandwidth problem, or if it's just the way it is. I'm hoping it's the former.
I posted elsewhere regarding this issue, but didn't get a decisive answer. You can see that thread here: http://discussions.apple.com/message.jspa?messageID=2581668#2581668

Hi Saul23,
It does depend on all parties having a "good" connection.
Realistically this is going to be at least or close to an upload of 1Mbps.
Once one party drops below an upload of 500kbps you can be certain of noticing a drop in quality.
It is best that the fastest Buddy (upload speed) is host.

IChat Video Quality vs. Bandwidth FAQ?

I have done some searching and have come across some video quality threads.
Most of my Video Conferencing is done between my Macbook or iMac 24 across Time Warner cable to another iMac 20. All running OSX 10.4.9.
It appears that the video quality will vary based on the upstream bandwidth availability. In my case I have 600-700kbps pretty consistently. This is pretty decent for a 1 person video conference. Not quite up to the standard I was hoping for but usable.
What is not even usable is doing a multi-person Video conference. In this case two local machines on the same wireless network and one machine across Time Warner cable (we use the same provider). When I bring the second local machine, the conference splits out properly but the video in each widow (other than my preview) is so blurry that it is completely useless.
I would be very curious as to the experience of others attempting to connect across the same service providers network. In this case we are connecting across Time Warner between Florida and Ohio. The performance should be rocking with at least 1MB upstream (I will have to check but I think I have 5MB up).
The other thing that I was wondering is if there is some way to tweak the iChat Video settings to force it into a specific video quality mode (and possible deal with some dropouts).
Sorry for the long post but I am hoping we can begin to compile information on bandwidth requirements and perfomance experienced with various service providers.
Thanks!
Jim

Thanks, I did both tweaks and the really improved the 3 way conference.
My speedtest is below and is on Bright House in Tampa. Note that the best that I achieve watching Connection doctor is in the 700 territors. I do tend to be able to deliver 20fps pretty consistently. But my bandwidth bounces around a lot. I am not a big fan of cable for quality and consistency.
[IMG]http://www.speedtest.net/result/145047165.png[/IMG]
Verizon FIOS is moving into my area and I believe they will offer much better speed than Bright House and certainly more consistency. RF is simply a nightmare to maintain.

Is the music-video quality worth $1.99?

This is my time line: I downloaded the iPod commercial (w/ U2 in it). I bought music videos.
I have to confess that the video and sound quality for music videos are way too low for $1.99. I expected the quality JUST AS IN THE AD but it is only a very small fraction of it. The commercial might be misleading. It is good but it does not reflect the reality of the product. Gotta check on that.
I understand that there might be limitations with the iPod. That's acceptable but what if I want to watch these videos in the computer? Shouldn't the software down-sample the videos for the iPod while maintaining a full-quality copy for desktop viewing?
You can legally download most of the music videos at the same size for free from well known sources (that are even related to Apple). Yes, some of the have lower video and sound quality BUT these are neither intended for HD TV viewing?
My two dollars: Make them larger and better and make iTunes install a reduced video for the iPod. Otherwise is only worth like $0.49.

I too am very disappointed by video quality especially for the price. If it had said it was 320x240 on iTunes Music Store I wouldn't even have thought about buying it. They are definitely misleading most people to think it's full quality. I know it needs to be 320x240 for an iPod but I'm down loading it to my computer and would expect at least 640x480 come on!! You should have to compress it for the iPod the same as you would with CD's. That's why I don't buy music from iTunes Music Store because the quality is too low for my standards. Now it's the same reason I won't buy videos either. Well thanks for letting me get that off my chest. Wish I had found these posts prior to buying my first and last item from iTunes, a Jane's Addiction "Ocean Size" music video... : (

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,
Justin

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

Video quality while chatting

While video chatting one-on-one the quality is great, but when video chatting with two or three people the video quality drops like crazy. No matter how small I make the window the images of the people with whom I'm chatting is super pixilated, and I'm wondering if there's anything I can do to improve the quality. The quality of the connection doesn't seem to be a factor either.
It's frustrating because all of the pictures of the three person video chatting look so clear... Seems like false advertising.

For info and others,
iChat depends more on Connection speed and the Bandwith it uses of that for good connections.
iChat reads the connection speed you have from the System Preferences > Quicktime > Streaming tab > Streaming setting.
If this is set to the default of Automatic it returns a 0 (Zero) to iChat and caps the bandwidth.
http://docs.info.apple.com/article.html?artnum=301641
If your connection speed exceeds 1.5meg use this setting as the max.
In iChat > Preferences > Video section > Bandwidth Limit drop down should be set to NONE otherwise it also caps the bandwidth.
The min Apple say is needed to multichat is 384kbps both Upload and download speeds.
Realistically there is a drop off in the H264 codec driven video quality when you add 2nd and 3rd or even a 4th person.
Ideally you need at least a 1Mb upload to maintain an excelent picture quality. This is for all people involved in the chat. The best solution is to get the fastest Internet connection Buddy to host the chat.

Video quality as low/high/HD

How to provide a video quality as Low, Medium, High and HD in flash actionscript. Thanks in advance..

Usually when discussing video quality, the "quality" is more or less a measurement of the amount of data that needs to continually flow into the video player to provide an uninterrupted display of the video. This is the video "bitrate".
So to provide 3 different "quality" videos, you need to provide 3 different video files, each rendered at a different bitrate (or displayed at different dimensions... see discussion below).
For example
Low: 400kbps
Medium: 1000kbps
High: 2500kbps
There is really nothing Actionscript can do to produce any of those. Controlling the bitrate is done in the video editing or transcoding software. Then you could create controls or buttons in actionscript to select between the separate video files.
More about video bitrate from this old post:
Video bit rate
One of the principle of goal setting is to "Begin with the end in mind". In this case it'll be very hard to give good recommendations because the end is not defined. So I'll just make a few assumptions and you can correct me as needed.
First, I'll assume that since you are converting to Flash, you want to deliver this video over the Internet. If that's true, then we'll have to make some assumptions on the Internet connection download speeds of your potential viewers. Let's just say that most have at least a 1.5Mb connection or faster.
OK, that would mean that a video bitrate of half that should usually provide a video download that is not interupped by buffering (most of the time anyway). So assuming a video bitrate of 750kbps, what would the optimum display dimensions be?
Before we decide, here's a little info about bitrate. For highest quality playback, the video bitrate is tied directly to the display dimensions. That is, the larger the display, the more incoming data is required to properly display the video. Think of bitrate in terms of a can of paint. If you have 1 quart of paint, you might be able to do a very nice job on a 32 X 24 foot area. But if you try to stretch that same amount of paint out over a 64 X 48 foot area, the coverage will not be nearly as good and you get poor results.
In the same way, a video displayed at 640 X 480 pixels will require 4 times the bitrate as a video displayed at 320 X 240 pixels to produce the same quality. So for example a video with a bitrate of 100kbps, displayed at 160 X 120 will produce the same quality results as a video with a bitrate of 1600kbps if displayed at 640 X 480.
So to boil it all down, video bitrates of 750kbps, even up to 1000kbps can usually get delivered of the Internet on most high speed connections. Higher bit rates may work for really fast connections but will cause problems for viewers with slower connections. Video display size has a direct bearing on the final quality. In the 750 to 1000kbps range, display size should be kept around 450 or 500 width max (and whatever height the aspect ratio calls for). Yes it can be displayed larger, but the quality will suffer.
Sound like your audio settings are fine, especially for Internet delivery.
As for framerate, maintain the original raw video framerate for best results. So if the video was shot at 24fps, leave it.
As for video converters, do you have the Flash 8 Video Converter? It works just fine for video to be delivered over the Internet. Remember, you are taking a Cadillac version of video (h.264 HD) and stuffing it into a Chevy body to get it to work over the Internet.
Best wishes,

--Color differences in exports - Need to maintain color quality...

Here's the scoop...
I'm experiencing color differences and sharpness of text and graphics - basically everything in video --- from one export to another.
In this circumstance, I screen cast Powerpoint with Camtasia. I export the video in Camtasia with these settings:
Quicktime - TechSmith Ensharpen Codec.
I import into Premiere, do my edits...then export H.264 Format --- with custom settings that match Camtasia Exports - frame rate, resolution...etc...
Data Rate in Premiere - played around with diff settings...went initally with 3 min 4 mbps max --- then tested 5 min 6 max --- same results. I export them with Encoder.
Results =
- Quicktime - TechSmith Ensharpen Codec = darker, richer colors with enhanced sharpness
- H.264 from Premiere = lighter colors with more of a flat/less sharp look
I've compared in both Quicktime and VLC players
I've read that H.264 can produce color differences. I want an export that will maintain colors of Quicktime - TechSmith Ensharpen Codec at a data rate of around 1-2mbps. Have any suggestions?
Big Thanks

Jim, appreciate the insight.
Prior to posting, I forgot to mention I did adjust settings in GPU panel.
I've tested multiple computers now on various players (VLC, etc..), all with the same result --- the color difference exists on every computer. Final video's will be seen online, not a TV.
In light of this…what I've deducted is that - I still need to find an answer to my original question.
Is there an export that will maintain the quality and colors of Quicktime - TechSmith Ensharpen Codec at a data rate of around 1-2mbps?
Virtually none of the computers that people will be viewing these video's on are going to be color calibrated. It'd be comparable to the computers I've been testing on…
If I'm not seeing this clearly, then obviously let me know…I could be mistaken.
Thanks again

Adobe Elements 12 - Video quality of downloaded DVD in editing software

Why is the video quality imported from a 1.4 GB mini disc into the Premiere 12 software worse then when I just watch it directly on my computer? It seems like there is a big step down in quality after I download it to edit in the software program. Why is this? Is there something I can do to maintain the quality of the original?

Beaver Dan
Thanks for all the helpful details.
Here is what I would like you to do.
Open Premiere Elements 12.
Go to File Menu/New/Project and, in the new project dialog, set the project preset to either NTSC DV Standard or Widescreen (depends on if you recorded 4:3 or 16:9). Before you leave the new project dialog, put a check mark next to "Force Selected Project Setting on This Project". Close out of there.
Back in the Premiere Elements 12 workspace, go to Add Media/"DVD camera or computer drive"/Video Importer. You will need to have you miniDVD in the drive tray. Will your burner tray accept the miniDVD for place in tray? Most do.
In the VIdeo Importer dialog that is opened, go to the Source: field at the top of the dialog and make sure that you DVD drive is selected there.
Your Video Importer should be populated with thumbnails. Uncheck all. Select the video files from the DVD-VIDEO. The names should be VTS_01_1.VOB, VTS_02_1.VOB, and so on depending on how long this DVD-VIDEO is.
Make sure that you have the Save In: field set to a named folder for this batch of VOBs. If you want the VOBs on the Timeline of the project as well as saved to the hard drive, make sure you have a check mark next to Add to Timeline. Then hit Get Media to get your VOBs into the project.
Do the Publish+Share/Disc/DVD disc export with the NTSC Dolby DVD or NTSC_Widescreen Dolby DVD preset.
Play back the DVD-VIDEO on DVD disc using your computer and one of its players for that purpose as well as the TV and its DVD player. Let us know the results.
We will be watching for further developments.
Thanks.

How can you keep the highest iphone 4s Video quality the same when exporting it from iMovie.

How can you keep the highest iphone 4s Video quality the same when exporting it from iMovie.

InDesign's PDF export engine does not transcode your videos, they are embedded exactly as they were in the original file. The Flash Player runtime which displays video inside PDF files may not show a perfect match to Quicktime etc. because most video playback tools aren't designed for a color-calibrated workflow, but they should be close.
The playback quality (blocking and aliasing) will be affected if the clip is not playing at 100% (screen pixels != video pixels) and in PDFs with the standard video player widget, that will only ever happen when you use 'floating window' mode. PDF pages have physical dimensions, so viewing them at "100%" does not make them match screen pixels.
If you don't mind the video clip being smaller than the media annotation in which it's playing, then use my free upgrade to the Acrobat playback widget - VideoPlayerX - which maintains 1:1 pixel scale until the page is zoomed out too far for it to fit. You can install the widget into InDesign so it's used by default when exporting.

Retaining video quality for screen capture export

I've spent hours searching all over the interwebs and trying every combination possible, but I cannot for the life of me get Premiere to maintain the quality of my video from a screen capture. This is for a software demo video I am making. Here are the settings for the video capture:
Recorded with ocam screen recorder (http://ohsoft.net/product_ocam.php). This produced decent quality, not perfect, but definitely readable.
Microsoft MPEG 4 part 3 (.AVI) codec
1024x768
30fps
6000Kbps bitrate
When I view the files in Windows Media Player or Quicktime they look fine (again, not perfect, but definitely usable)
However, when I import them into Premiere Pro the preview adds artifacts, especially around black text on white background.
My sequence settings in Premiere match the original video:
1024x768
Square pixels aspect ratio
30fps
Exporting produces the same problem, artifacts all over.
Oddly, sometimes the artifacts disappear, such as when a window is moved with the cursor. Suddenly all the text in that window gets clear for a second.
Any help would be greatly appreciated.

Over in the PrElements forum, Steve Grisetti (may be spelled wrong) who literally wrote the book http://www.amazon.com/Muvipix-Guide-Premiere-Elements-version/dp/1479311200/ has said that he uses Camtasia for all of the online tutorials he creates

Comparing video quality of AVCHD BluRay discs using Final Cut Pro Share vs Compressor

Up front, I will admit to being a newbie when it comes to using Final Cut Studio 3 and would appreciate some feedback from the Apple forum experts.
I have spent a lot of time trying to determine how to achieve an optimum group of Compressor 3.5.2 settings so that the playback video quality of an AVCHD BluRay disc is equal to or better than one created by using the simpler auto settings of FCPro Share, version 7.0.2.
When using Compressor’s auto/default maximum settings, I experienced the same error message reported in:
Error MessageDuring Creation of Blu-ray Disc in FCP and Compressor 3.5
https://discussions.apple.com/message/12073794#12073794
I have since made some Compressor AVCHD Discs with smaller bit rate settings and compared video quality with a single FCP Share AVCHD disc. Both seem to be equal in providing a very good video when viewed on my new Panasonic DMP BDT 310 BluRay player. However, the Compressor AVCHD discs show some motion artifacts not present with the FCPro Share version, especially when scrolling text or when objects are moving through the field of view, and visible artifacts are seen from a stationary chain link fence and other lattice work in the background of the video sample.
My sample video used for the comparisons between Compressor and FCP Share discs is a 21 minute duration home movie, originally captured from a mini DV, Canon HV30 1080i camcorder using ProRes HQ encoding(1440x1080), and dragged into FC Pro 7.0.2 timeline where 10 chapter markers have been inserted.
To create an AVCHD disc using FCPro Share, Markers are used to set the IN and OUT points, Select IN to OUT from the timeline, pull down File Menu Share, Select Create BluRay from options in pop out Share pane, and designate output device along with picture files for Background, Logo, and Title options. When these are completed, click on Export. My 21-minute video required almost two hours for encoding including about 10 minutes for burning. This accomplished on an iMac 3.06 GHz Intel Core 2 Duo.
To prepare this same 21-minute video for use with Compressor, I again Select IN to Out from the FCPro timeline, but this time use File Export as a QuickTime Self Contained movie including Chapter markers. Then Open Compressor, choose Create BluRay from Template pane, right click on the down arrow in the Batch window and load the QT self contained movie file. From there I went to the Inspector window and tried various combinations of bit rate settings along with Frame Encoder options such as Better or Best motion parameter controls.
I have tried the following combinations of Bit rate settings along with varying Frame Encoder controls and burned an AVCHD disc for each example:
Example A
Compressor set to 6 Mbps Average and 8Mbps Maximum, Frame Encoder settings OFF. Approximately 4 hours to encode although the time remaining estimator indicated a larger value of ~7 hours; not an accurate estimator at all.
Example B
Compressor set to 6 Mbps Average and 8Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motionadaptive)” settings. Approximately 4 hours to encode, not the 13 hours that were estimated.
Conclusion: Comparing A & B Compressor versions, Disc B showed some improvements in reducing motion artifacts over Disc A.
Example C
Compressor set to 13 Mbps Average and 15 Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motion adaptive)” settings. Multipass checked. DeInterlace was checked. Unknown hours to encode; about 8 hours done overnight..
Conclusion: Disc C showed some minor improvements reducing motion artifacts over Disc B
Example D
Compressor Auto settings,i.e., 15 Mbps Average and 17 Mbps Maximum, Frame Encoder settings ON, using “Better (Linear Filter) and Better (Motion adaptive)” settings. Multipass checked. Approximately 12 hours to encode, done overnight. Inserted disc next morning after the overnight encoding was completed, and a few minutes later an error message pane appeared that the maximum bit rate had been exceeded. This message was consistent with the Apple posted thread referenced above. Unfortunately the long overnight encoding was wasted.
It seemed to me that the best Compressor settings for suppressing the motion artifacts were displayed by the disc burned in Example C, i.e., 13/15 Ave/Max Mbps with“Better” Motion settings in the Frame Encoder.
However, when this disc was compared to the AVCHD Disc burned using the FCPro Share, the latter still seemed much better. I do not know what the auto bit rate values are as set in FC Pro, but for me, the quality is quite good AND the motion artifacts are significantly reduced, especially evident with the scrolling text.
Sorry about this long post, but I thought the detail would be necessary for the experts, and maybe helpful to others trying to get started in this BluRay arena. Did I misuse Compressor? I think the sample video exported as a self contained QT movie was the right thing to do? Not sure where I went wrong.
Thanks in advance for Feedback and Recommendations. For now, I’m going to stay with the simpler process using Final Cut Pro Share function.
BoBo

Thank You, Brad, for responding; glad to hear I'm not the only one having similar Compressor issues.
You may have hit on something. Perhaps Compressor's use of H.264 encoding was the reason for my motion artifacts? And perhaps Final Cut Pro Share retains the 1440x1080 quality as it burns the AVCHD BluRay disc?
I had Toast 10 for less than 30 days a couple of years ago, and was lucky to get a refund.
What version of Toast do you have? Wondering if new Toast 11 has improved previous bugs, especially upgrading its Chapter text, pictures, music. I would go back to Toast if it came close to mirroring DVD Studio Pro, or even iDVD capabilities.
Thanks,
BoBo
