Broadcast Gradually Loses Quality

Copy and pasted from my topic on creativecow.net:
Hello everyone. My name is Danny, a Justin.TV broadcaster who goes by the name iMoogle. I recently bought a new computer along with an intensity pro, and have tested it using Adobe Flash Media Live Encoder (FMLE) to upload the stream to JTV. The video is perfectly fine for the first 7-8 minutes of intense action, but after that, many things start to happen:
- The video bitrate show in FMLE starts jumping from very low to very high bitrates, nowhere near the selected bitrate (700kbps). I've seen it jump from 50kbps to a whopping 2000kbps for unknown reasons. It's not very noticeable in the video, but an inconsistent bitrate can never be good. When it streams perfectly fine, it only jumps between the range of 650 and 750.
- The FPS starts to drop dramatically. From a very very steady 30FPS, then gradually down to 28, then 25, then 22, then if I choose to keep the broadcast on even longer, down to 10FPS! But I usually stop the broadcast after around 22 because the video becomes way too choppy for my viewers and I.
- The audio becomes out of sync, and gets more and more delayed the longer I let the FMLE stream to JTV.
Here are some videos of how good it is from the start, then how bad it gets in the end...
GoW2 (360) - http://www.justin.tv/clip/4983dc87147c9fbe **I cussed a bit in this highlight. Just a warning =P
CoD4 (360) - http://www.justin.tv/clip/910b1ec95d278003 **This is after 14 minutes of idling in the lobby.
The strange thing is, that if I stop FMLE, then start it again, it will stream perfectly fine for 7-8 minutes then it will show these symptoms again, gradually getting worse. My computer is pretty good, and my CPU usage never goes over 50% while broadcasting.
Intel Core 2 Quad Q9550
4GB of RAM
Geforce GTX 260
About 3.5 Mbps upload speed (doesn't matter what my FMLE settings are put to. Even if I have a stream of only a total of 400 kbps, the quality will die down after 7 minutes)
Update: Upgraded from Vista 32-bit to Windows 7 64-bit. Still no good.
I'm going to try broadcasting with my old Dazzle DVC100 capture card and see if FMLE does the same thing. Update: FMLE indeed does the same thing and lags the broadcast, even though it worked perfectly fine on my old computer with no lag whatsoever. This cancels out the possibility of a problem with the Intensity Pro capture card. There's something wrong with my computer but I can't pin it down.
Any help is appreciated. Thanks!

I watched your videos. At first look, the problem seems to be of insufficient bitrate and lack of CPU. But as you mentioned that your CPU usage never goes above 50%, cpu shouldn't be a problem. If the bitrate is insufficient you might observe choppyness in the video. When you say that the problem occurs after ~7min, do you encode the same thing everytime after 7min? I mean, as the complexity of the content increases vp6 codec will try to budget more bits for the content. If it is unable to do so, video quality will suffer. Please attach FMLE session log file of the choppy session. If you are creating a local flv file, please verify whether the problem exists in the file.

How many times can you "Export - Quicktime movie" the same ProRes 422 file until it starts to lose quality?

Lets say you are done with your project & you want an uncompressed copy of it as your master. If you keep importing it back into Final Cut Pro, & keep exporting (Quicktime movie), will it ever start to lose quality?

I've never seen a number given, but would think it is very high.
Apple describes ProRes here:
About Apple ProRes
And in that document says:
"while remaining visually lossless through many generations of decoding and reencoding."
I don't think I've ever seen degradation caused by recompression or multiple compassion, but as a workflow if you output a master file, then re-import it to add graphics and export that, you would only be 1 generation down from the master file. If you wanted to make multiple versions, you can always go back to, and re-import, the master file and make the changes, then export, so all you exports stay only 1 generation down from the master file.

FLASH VIDEO LOSES QUALITY WHEN "WMODE" SET TO TRANSPARENT

I have a flash video beside a roll out menu. When I set the

Whatever is Created in LiveType....Loses Quality in FCE ......?

I've noticed no matter what I create in LiveType after it is rendered in FCE as a Quicktime movie (LivetType clips used as intros) it loses Picture quality. It becomes very grainy, why???? How do I rectify this problem?

Ok. This is the thing that is throwing me off. I pplaced the livetype movie onto a movie and it improved ever-so-slightly. I understand that in livetype it is created in the highest quality and the moment you place something like that onto a dvd it loses quality. Granted I don;t have a blue ray burbner so I can keep the quality but I place some of my videos on Vimeo.com that accepts HD videos and when I placed it on there site it still looks the same. It only looks good in the LiveType editor or when i just render it as a movie. Final Cut kills the quality. So much for such creating HD videos when I can't do a simple intro in HD its more like SD.

Why do Apple photos lose quality when imported to Windows?

When photos taken on an Apple phone are imported to Windows Photoshop Elements 11, the photos seriously lose quality. Why?

A bitmap image (such as a .jpg or .gif) is basically a grid of colors, which are represented by the values (numbers) for how much red, green, and blue of each pixel in the grid to activate when the image is displayed on a monitor or printed.
Some bitmap images (including .jpgs) can also specify a color profile. Applications that support color profiles will adjust the color values before they are displayed. Photoshop honors color profiles, Fireworks does not. Fireworks does not, because most browsers do not; Fireworks displays images as they will be seen on the Web. Photoshop does, because Photoshop can support color profiles for print devices.
Photoshop has a default color profile. If you open an image that does not have a color profile in Photoshop, Photoshop will apply its default color profile to the image and adjust the color values it displays. Photoshop shows you modified data; Fireworks shows you the raw data. This is not a quality issue, because nothing has changed with your image and the applications are operating exactly as they are supposed to.
What you want, I think, is to be able to open your image in Photoshop, and then save the richer view of the colors you see, but without a color profile.
Read this article: http://www.viget.com/inspire/save-for-web-simply
You can find out more about this whole issue if you query your favorite search engine for the phrase "photoshop save for web color shift" (without the quotes).

Screen Capture Video Loses Quality When Imported Into iMovie - WHY?

I am using screen capture software to make a video of my screen at 1024x768. The video is for a tutorial. I want to use iMove to get things like transitions and such into the movie, and to add text and audio. The problem is that, although the video looks great in QuickTime, it loses quality significanly when I import into iMove. The text on the screen is blurry, and the quality of everything else is terrible as well.
Is this s limitation of iMove? Can screen capture video be imported? Does it only work with DV?
Also, I tried to convert the file to many other formats, from QuickTime to MPEG-4, so it's not the file type.
If anyone can help me out, I've be very grateful.
Thanks!
iBook G4 Mac OS X (10.4.5)

Your dimensions are getting in the way. iMovie converts your 1024X768 to a DV Stream file that is 720X480.
One workaround would be to set your display resolution smaller. Try 800X600 (if your windows fit that size).
If you're using Snapz Pro you should set your window capture to 640X480. This size will import nicely into iMovie.
An even better way would be to do all of the work using QuickTime Pro. Again a 1024X768 QT.mov file would not fit on the most common display settings used. When you add the QT Player window the controller would be below the screen and not accessible for most users.
800X600 would make a better file (smaller, too). It would still be 4:3 aspect and would also import into iMovie.

How I can export files from CS5.5 to send for further editing in CS6 and no lose quality?

how I can export files from CS5.5 to send for further editing in CS6 and no lose quality?

If all you need for further editing is the contents of your Timeline,
then you should follow Harm's sage advice.
Lagarith Lossless Video Codec
http://lags.leetcode.net/codec.html
Ut Video Codec Suite
http://www.videohelp.com/tools/Ut-Video-Codec-Suite
But, if you will need all of your source media files to continue the edit,
you should consider using the Project Manager.
Trim or copy your project
By using the Project Manager, you will be continuing the edit
with the original media files and there will be no quality loss.
Be aware that once you have edited the project in CS6,
it will be problematic (but not impossible) to return to edit in CS5.5.

EXPORTING 7D FROM FC EXPRESS LOSES QUALITY- HELP

Hi
I have 7d footage which I'm trying to export from Final cut express and when I do it loses quality and comes out a little pixelated.
The video is 1920 x 1080, 25 fps, in 'Get Info' it tells me Codecs: H.264, Linear PCM. The total bit rate is 46,000- 47,000.
In Final Cut the easy set up for the project is HDV-Apple Intermediate Codec 1080i50.
Then I export it at Compression Type: H.264. Keyframes every 25 fr. Encoding: Best Quality.
And export Dimensions: 1280x720 HD
What am I doing wrong?
Please Help I need to sort this ASAP.

you've misunderstood it's a quicktime mov. when i right click on it(i use an imac) and click get info then it comes up with a bit of data once of which says codecs:h.264,linear pcm- which is maybe just suggesting what codecs to use when compressing it- ignore the h.264.
"Also, because the 7D video frame size is 1920x1080 you need to use the AVCHD Apple Intermediate Codec 1080i50 Easy Setup in FCE"- this option is not given in FCE HD.
I know MpegStreamclip and I'll try that see what happens, this is the first time I've worked with 7d before just used 5d. I also have pavtube video converter.
Thanks for helping it is very much appreciated

Scale without lose quality

Video that will be sell on DVD. My video is 1920x1080 30fps.
There are few clips that need to be zoom in but I want to know if there are can be scale 150% without lose quality.
Is there any filter to prevent it? Or just limit percent on scale?
I saw somewhere there has some kind of filter for photoshop that can zoom to eye from full body without lose quality.
Thought maybe somewhere there is for final cut pro 7.

>I want to know if there are can be scale 150% without lose quality.
Nope. If you zoom in that much, you are blowing up the video by 50%. You are making the compression artifacts associated with that format bigger.
>Is there any filter to prevent it?
Nope.
>Or just limit percent on scale?
20% is typically the most you can do without being noticed. 50%...yeah, that will be noticable.
Photoshop...stills...you are dealing with a lot more pixels, a lot more detail (depending on the still) than video. Video is 72dpi...period. And your dimensions are 1920x1080. That's all you got.

"Scale to Frame Size" option - won't I lose quality?

Hello,
I have a sequence in 720p and I have most of the videos in 1080p. I want to scale all of them once, so I select them all, go to Clip->Video Options->Scale to Frame Size. But, the Scale Size shows all the time as a 100%, even after the clips are scaled down.
Question 1: Won't I lose quality if I will zoom in (but go not further than 1080p)?
Question 2: Also, I understand, that I cannot go further than 150%, right?
Thank you.

I do not want to scale (Using Motion->Scale) each clip separately. I want to do it for all clips
Jeff has it technically right, but missed part of the question.
I believe the remaining part of the question is "How do I set every 1080 frame to 67% so I can use that as a starting point? All at once."
Answer: Set one clip to 67%. Copy that clip. Then, select all of the other clips and "Paste Attributes". Now all of them will be set at 67% and if you decide to zoom in to 100% you will have no quality loss.
Be sure to do that before you change any other attributes of that clip. If you have, don't worry. Just turn off that effect temporarily so you can copy just the motion effect

Do you lose quality doing this?

I think i asked this before, but i can't remember what the answer was.
If you open a JPEG, modify it and then save it as a TIFF, do you lose quality?
Thanks.

No. Tiff is not lossy, so you will not lose quality. In a JPEG the quality loss comes when the compression is applied when you save and close the file.

Scale to frame size: clip lose quality

Hi
I'm working with Premiere CS3.
I captured a clip from a Sony HVR-Z1E over IEEE1394 in a HDV Project. Settings: HDV 1080i, 25.00 Frames/Second, HD Anamorphic 1080 (1,333), upper field first.
Afterwards I import the clip in a DV Project. Settings DV PAL, 25.00 Frames/Second,D1/DV PAL Widescreen 16:9 (1, 422), upper field first.
In the timeline, I scale down the clip manually (under effectsettings/ move/scale)the clip to 53.3%. The clip lose quality. Pixels seems to be bigger. The same also happens if I check "scale to frame size".
Can anyone help me? Thanks in advance.
Regards, Corinne

Hi
Thanks for your reply. Yes that's right. But in CS2 the lose of quality was much smaller then in CS3. The clip was after scaling to 53.3% still useful. That can't be the problem.
I thought thath SD DV is upper field?

Images lose quality when imported into Pages

Hi,
when I import images into Pages, they lose quality. They are normal jpg files.
After the import they look a bit fuzzy. I dunno why...
thanks

In the Inspector "Measures" there is a button allowing us to reset to the original size.
Of course, the picture will be smaller than the blurred one
or
will be too large and parts will be hidden.

Someone knows how to minimize size video-file without lose quality?

I have been trying but I can not find the settings to minimize my video-files in size without lose quality in premier CS3,can someone help me please?.
the file is a mpg exported mpg2 from imagemixer3SE software that comes with the camcorder I have got.
As well I have got problems finding the audio.I explain:when exporting the mpg to premiere the audio is not there, but in other programs as after effects you can see there are audio.I readed somewhere that provbably the programe forgot to import the codec and I have to find the file .nll and import it to premiere but I do not know if this is the right answer.
Please help!!!
Thank you very much,
Asyn

Unfortunately, you have posted into the Premiere forum. This is an older series of programs, prior to the introduction of the Premiere Pro line, with PrPro 1.0.
John has hit on part of your problem - MPEG-2. It is highly compressed to begin with. The best format is, as he suggests, DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio. These files will be larger, but will edit better, and you are not likely to experience any Audio issues.
Then, for Export, you have some choices, but you must remember that comprimising the file size and bit-rate WILL diminish quality. How much, will be a function of the CODEC chosen.
What is your intended delivery, DVD-Video, or something else?
I'll bet that Curt, or Jeff, will move your post to the PrPro sub-forum, so look for it there. You will get many more responses in that forum.
Good luck,
Hunt

DVD don't want to lose quality

Hi I am loading in DVD footage (from the client - all legal) and was converting in to DV compression in MPEG Streamclip. I am going to deliver it back as a DVD and was wondering if there was a better way to compress this so as not to lose quality of footage.

Captain Mench's solution is the only one to minimize the loss of quality.
What are you are trying to do by demuxing footage from mpeg2 is take already compressed footage, and then uprezzing that compressed and artifacted footage.
Then editing it, and recompressing the footage.
It ain't going to be like the original footage because there are atleast two recompressed, and one uprezzing of the artifacted footage.
His suggestion at least minimizes the process, but doesn't eliminate it.
