How to republish stream with lower quality

Hey guys, I was wondering is there a way that I can receive stream on my broadcast server and then republish that stream with lower quality on the same broadcast server. I was reading server side API reference but I couldnt find anything like that.
Only thing I found is to use %i in FMLE Stream field and then broadcast same stream with different bitrates, but can I take live stream that is being broadcasted and republish it with lower quality/bitrate on the server side somehow?
Or there is another way to achieve this?
I am running FMS 4.5 and I am using FMLE to broadcast video to the server.
Thank you for your answers.

FMS can't transcode streams. What you could do is use FFMPEG to pull the stream from FMS and publish a transcoded stream back into FMS.
Alternately, you could use Wowza Media Server and their transcoder plugin (fairly easy), or Wowza and Xuggler (requires a fair amount of programming)

How do I import with highest quality ?

How do I import with highest quality ? Should I chose ''optimized media'' when importing or chose nothing ?

Hey Marcs,
The answer is no, but I suggest you have a read of some of the excellent articles out there about this to understand whats going on, and how to choose settings on import, and when sharing.
Here is a good article for example ...

HT1044 Will an iphoto order print with low quality warnings on it?

Will an iphoto order print with low quality warnings on it?

I think so but if you're orderikng large photos they may be a bit fuzzy depending on the pixel dimensions. What are the pixel dimensions of the image giving the warning and what size print are you ordering?
Here are the results of a print test that I ran. The pixel dimensions are the minimum that won't give a warning for the sizes shown:

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 work with low quality offline media efficiently?

I have a late 2013 rMBP with an NVIDA GPU that is a fantastic platform for editing when I am travelling. The downside is that it doesn't have allot of storage and when I have high bit rate material it can struggle. I often shoot DNxHD 220 on an Atomos Ninja 2 and for a recent project I used AME to convert all of this to DNxHD 36. I then kept the original files on my NAS and copied the low quality files to my laptop to edit while travelling. This worked really nicely, but when it comes to rendering out the finished project it can be laborious to switch the media files. I have numerous clips and I had to go to each one and follow these steps: Adobe Premiere Pro Help | Create clips for offline editing
Is there a way of replacing all clips in a bin rather than doing it one by one? This time I had 30 clips which was annoying but not the end of the world. For future projects this could be many more clips and currently the process documented in the Premier help is going to be time consuming and annoying. Does anyone have any tips or are there new features in the latest CC updates which allow this type of functionality to be done in bulk?

shooternz uses a LOT of digital intermediate workflow ... he might have ideas on this, hope he chimes in ...

Duplicating stream object to new stream with lower resolution

Hi all generally I have a question, Is it possible for ams to split my original live stream to a new stream but with lower resolution, so i have two streams one with high resolution and one with low resolution?
If not I how does it Adobe Flash Media Live Encoder do? I can steam up to 3 different resolutions from one camera object. Is it possible to do also from flash?
I want to built a multi user conference application. But have some cpu usage issues, so I need a additional lower resolution stream to use for the miniature views.
Could You help me with this, any tips how could I do such a thing?
I using rtmp protocol to communicat and adobe media server 5.
Sorry if a similar thread was already published on this forum.

Thx 4 the replay.
So maybe I could do something like this:
I am able to send two streams from one camera but they both have the same resolution.
Is there any way from flash app to send two streams from one camera with different resolution like FMLE does?

My iphone still plays songs with lower quality instead of 256kbps

I enabled iTunes match on my iPad and iPhone 4S. However, it already
has my songs already synced on them and when I play songs it plays at
lower quality than at 256kbps as claimed by Apple.
One option is to delete all the songs on the iPad and iPhone. But that
will require me to delete every song individually. How do I solve this
problem?

When you turn on iTunes match on your iOS device it should warn you that it is going to delete your songs. You will then need to redownload the ones you want to listen to from the cloud.

Problem with low-quality recordings!

I have been using GB for a few months now and have made some very good demos (very crisp and clean recordings) as of tonight, it sounds like all of the recordings (directly through the mic) are low quality...any reason why this would happen?

What kind of mic and how are you "getting" it into the Mac? Have you changed anything however insignificant in the way you are recording?

IMovie and iDVD help with low quality

I am working on a large project that consists of 480 still photos that will be set to music with motion, etc that is 1.3GB total. When I import them into iMovie the project quickly becomes 15GB+. I then exported it full quality to iDVD which compressed it to around 2.5GB. My issue is that the quality is bad...wavy type pictures, etc. Is this because I have too many pictures and the project is too big? What should my settings in iMovie be to get the best quality project. The photos are high quality shot with a digital SLR and look great by themselves so I know it's not the pictures themselves. Any help and advice would be greatly appreciated!!

There are a heap of threads on how to improve the quality of your photo's from iMovie to iDVD. Any reason you are using iMovie for a slideshow? Do you have video in the project as well? I say this because iMovie is essentially a video editing tool, rather than a slideshow application. I use either iPhoto, FotoMagico or iDVD direct to make my slideshows. ALL much better quality than from iMovie.
My first project was a still photo slideshow made in iMovie and I was really disappointed with the end product (pretty much as you described it). It was recommended to me to try a couple of things.
1. Import your photo's with KB turned on (although this seemed to make my photos worse - it seems to work for some).
2. DON'T EXPORT or SHARE your iMovie with iDVD. Rather, save it and close iMovie. Then open your iDVD project and your finder where you will find your project listed in the movie folder. Drag it's virtual icon and drop it onto your iDVD menu. I found this worked particularly well for me. If you DO export or share with iDVD make sure you don't allow it to re-render things (it asks permission). That also may make a difference.
3. When you eventually go to burn your disc, save it as a disk image (the option just under the burn button in iDVD). Once it is saved to disk (this will take a while to render, so perhaps do it over night) then you can view it in your DVD player and if all is ok, burn it through Disk Utility or Toast at a speed of 1x or 2x.
Hope these ideas provide some help.

How to play HD in low quality

Hello.
I have Sanyo’s latest Xacti gizmo VPC-FH1, which shoots “Full” HD at 1920x1080. The MP4 clips are obviously huge, at some 3MB per second. I can play the clips fairly well with QuickTime, but it’s a different story in Final Cut 6.
Whether in viewer or in canvass (with audio tracks deleted for good measure) it plays for two seconds and then freezes and just skips to a frame a few seconds ahead every few seconds. Downsizing even down to 12% makes no difference, and even if it did, it’d be way to small to be any good for editing.
I remember having similar issues with 1080p back with the HVX200, but I think I managed to downgrade the playback/render quality to a point where it played smoothly.
I’ve messed with different settings now, to no avail.
There’s user preferences, systems settings, timeline setting, RT, etc, etc...
What can I do for the clips to play smoothly?
I have a 2Ghz Core Duo 15” MBP with 2GB 667MHz DDR2 SDRAM.
For future reference, is there a MacBook that could play these clips smoothly without sacrificing quality?
Thank you much,
MaW

What a bummer.
Now I'm stuck with a just-about useless camera. I really need something as small as the FH1 (it's TINY).
Hard-drive camcorders record MPG2, which I assume makes them just as useless.
Is then MiniDV the only choice for a sub-$500 1080i/p camera that will allow me to edit footage without converting?
If so, any tips on the smallest one out there?
Google came up with Sony's DCR-PC55, but it's four years old and only does SD...
Do you want good OR do you want cheap? That is the decision you need to make. Also, tiny tends to be the opposite of good.
P.S. AIC converted it best; ProRes(Lo/HQ) left it pixelated for playback. But it takes about an hour a minute, and increases the file-size tenfold, so it's no good anyway.
Yes, your actual editable video file is going to be 10x bigger than a MPEG-4 file. That is what you want.
P.S. 2 "....FCP is converting your video behind the scenes which is causing all your problems."
If that's the case, then my oldish MacBook Pro (2GHz Duo, 2GB RAM) has enough juice to play the 640x480 MPG4 clips smoothly, but not the HD ones. Could the latest MacBook (2.5/6/8GHz, 8GB RAM) could play the 1080p30 clips smoothly?
No, you still have the same problem. MPEG-4 files are non-editable. You really need to convert to an editable format and then bring that into FCP. MPEG Streamclip is going to be your best choice.

How to save streams with amarok?

Hi!
When listening to internet radio I can rightlick on the stream then Manage files and then "Copy track to location..." but it doesnt work it says "The following file [filename] could not be organized."
Is there any other way to do it?

Are you talking about saving the audio content or the stream location?
You can use VLC and Amarok to record the audio content of a stream.
1. Right click on the stream in Amarok and click Copy Tags to Clipboard.
2. Paste this somewhere and extract the URL from it. For example http://12.345.67.89:12/stream/1111
3. Open up VLC and go to File --> Open Network Stream
4. Paste the stream in the HTTP/HTTPS/FTP/MMS URL textbox.
5. In the Advanced Options section below, check Stream/Save and click Settings
6. In the Outputs section, check File and enter a filename for the recorded stream
7. Check Dump raw input because the stream is already in an mp3 format.
8. Now you can open up the file you saved in Amarok
If you were referring to saving the stream location, it is the URL extracted in Step 2.
This works with Amarok 1.4.5 and VLC 0.8.6b.

My Nokia 701 saves photo with low quality

1. I set my camera for making picture with sizes 6M (16:9)
2. I took a photo and then I checked the file - it has resolution 3264x1832 but only 823k
It is too small for this resolution!!! If I will print it by 10x15, 20x30 or large it will be horrible picture.
Could you help me? What should I check or set in my phone for taking nice photo for the big resolution
Thank you

I tried with another brand as well, with the resolution 3264X2448 (higher) and the sizes of the photos were around 1-3MB. This is normal to all mobile phones and changing the brand will not make much difference for the picture size.
You can find more about the camera from here > Expand all > Multimedia.
If you think there is something wrong with the device, you can always try the actions below and see if they make a difference:
Make a back up with Nokia Suite. Type in *#7780# = soft reset, no data lost.
Reinstall the phone software. The process is the same as when updating with Nokia Suite, but at the end select "Reinstall".
Type in *#7370# = hard reset, phone memory will be wiped. Restore back up.
Hope this answers your question.

How can i choose a lower quality print density when printing from firefox on my Mac. I cant move the slider along the scale ( I can when printing from the computer).

I can't change the print density when printing from Firefox. It is set at standard and although there is a "slider button" to use for choosing less or more density, it can't be moved. I can tick "grayscale". I can choose the density when printing from the computer. I have a Mac

I also have this problem where I used to be able to shrink a 2 page doc to a single page. Since upgrade to FF4 it no longer works - but you can choose say 60% and it will work. All used to work fine in FF3
