FLV file size vs longer WMV file

When I created a FLV file of a live presentation (narrator on
screen demonstrating products, etc), it came out to 8 mb for a
320x240 window size. However, one of my trainers just recorded a
Camtasia (or was it Captivate, we have both) presentation, which is
basically a narrated Powerpoint presentation. It is over an hour
long, full screen and only 6 MB! This is a major difference. Does
anyone know why this would be? I have a couple of theories, but I'd
like to hear from someone else.

Sure - I use both so here you go:
FLV is a movie file. There are so many still images depending
on FPS and there is also a sound file embedded inside (so to
speak). So if you have a 1 minute video at 30 FPS - you have 1800
still images in a row that are compressed.
Captivate creates a swf file, basically a lot of keyframes
and some still images. If you created a file in flash with a few
backgrounds and some mouse movements the file will not be that big.
Every background used is just a still image, so there is probably
about 1700 less images used for this project.
So, Captivate is not creating a movie, but a swf file like
Flash. If everything was exported from Captivate as a mov, mpg, or
avi the file size would increase dramatically. The sound is also
probably encoded very low, like 128k which makes the file more
compact.
Hopefully now you can see why there is a big size difference
in the two.

SWF and FLV file sizes

Hello,
I have an flv file and the same flv file in an swf file. Both
files are the same size. So, it seems that it doesn't matter,
whether you import an flv file or an swf file, to keep your file
size small. Is this correct ?
Thanks,
Paul

> I have an flv file and the same flv file in an swf file.

> the
> same size.
That's just a coincidence.
There is different baggage / overheads with FLV vs SWF. So
you will usually
get some differences .. sometimes SWF smaller, other times
FLV. However,
the actual video payload is the same in both, and the audio
is similar too,
and they are the bulk of the file size. So there shouldn't be
a huge
difference in file size between SWF an FLV.

Converting .flv file to .wmv

Hi All,
I have done video recording example but I want to know how do
we can convert .flv file to .wmv file.
If any one know Please help me..
Thank's
sangati

As far as I know, if you want to convert .flv to .wmv file,
you need a third party to help you complete the progress, such as
Moyea FLV to video converter which
can convert FLV files to video and audio formats such as WMV, AVI,
MPEG, MP4,3GP, MOV, MP3,3G2, WMA, DV and etc.

Premiere Pro is no longer reconnecting certain FLV files

I have a clip that premiere is reporting as "disconnected media". It is right where it started, and the directory has not changed.
When I try to reconnect the media (which is the exact same file name still), the file is greyed out in finder, so I am unable to reconnect it. I'm also unable to import the clip new.
Why is premiere preventing me from dealing with this FLV file? It plays perfectly find on VLC, and it is not a corrupt file.

Internal or external drive, and if so, what connection?

.FLV files ..why do some play in HTML and others don't?

hi,
I am using dreamweaver 8 to embed 'FLV videos into html
webpages.
the problem is that when I embed and test some flv files, the
player shows up on the page and the videos play fine,
but when I try with a couple of other flv files, these files
do not work - a blank screen shows up (though when I right-click on
the screen where the video player is supposed to be, the flash
drop-down menu appears).
I know that the Size of the files is not why these files are
not working, and I have the latest version of flash player
installed. Also, I'm sure I have not made a mistake in the code,
and I suspect that it is something to do with difference/s in the
files themselves... ?
If you need any further info, please let me know.
this is quite frustrating - so please help.
thank you.

wutronic,
Maybe the following bits from the following Adobe page may be relevant:
Considerations
You can use the Live Corners feature multiple times on a corner, and modify either the radius or the corner style. However, if an associated anchor point in the corner is dragged or manipulated in such a way that the roundness is lost, then the widget will no longer appear for that corner.
Maximum Angle Limit
Users have the option to hide the Live Corners widget
for corner angles greater than a specified value. You can specify this value in the Preferences
> Selection & Anchor Display
> Hide Corner Widget
for angles greater than field.

Difficulty using hardcoded swf file to display flv files

Hi,
I have created a swf player using the flvplayback component to display flv files. The document in flash is 275 pixels wide by 130px pixels long. I also have my video component (flyPlayBack) set at 275px by 100px to display the playback controls. My flash code is my simple like the following
import fl.video.*;
var myflashvars:Object = new Object();
myflashvars = this.loaderInfo.parameters;
var fullVideoPath:String = "";
for (var item:String in myflashvars)
if(item == "filename")
fullVideoPath = myflashvars[item];
videoPlayer.source = fullVideoPath;
So using the above it should play the video and does.
(1) First question is I tried playing 2 different videos in my html code.
<object classid='clsid:d27cdb6e-ae6d-11cf-96b8-444553540000' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=10,0,0,0' width='275' height='130'>
<param name='allowFullScreen' value='true' />
<param name='movie' value='moviePlayer.swf' />
<param name='wmode' value='window' />
<param name='scale' value='showall' />
<param name='flashvars' value='filename=sample_sorenson2.flv' />
<embed width='275' height='130' allowFullScreen='true' type='application/x-shockwave-flash' src='moviePlayer.swf' pluginspage='http://www.macromedia.com/go/getflashplayer' wmode='window' scale='showall' flashvars='filename=sample_sorenson2.flv' />
</object>
Just like above works fine. But I tried playing 2 different videos, the first video image is below
The second video image is below
I notice the video sizes are different but not the video player size, is this to do a thing called aspect ratio? Is it possible to change this using my simple actionscript code above?
(2) I also tried the full screen button but the video only takes up part of the screen, as shown below. sorry about image size.
Is this a common occurance, is there a way to access the buttons on the flyplayback instance using actionscript and overridding the behaviour? Any advice upon my current situation would be much appreciated. Thanks.

To me the first two screen shots look like you set the wrong aspect ratio/screen size. I don't see any scaling of the player at all... only black bars on sides because the video didn't fill the entire video player display.
And yes, there is a much more powerful and versatile means of displaying Flash video, called NetStream. You can design your own player and have better control over the display. I always use NetStream rather than the FLVPlayback.
But if you are having sizing issues introduced during the creation of the video... then the player itself is not necessarily going to fix that. You need to know the correct display size and aspect ratio for each video you plan to display.
However, you can somewhat adjust the display size for each video using some actionscript... as you see here:
http://www.cataractvideo.com/cv/physicians/cataract_surgery.html
an example of a larger (high brandwidth) version and a smaller (lower bandwidth) version... depending on which button you click.

FLV File Import Error - Unrecognised Compression !

Hi,
I am getting an error message "Unrecognised Compression" when trying to import an FLV file into Premiere Pro CS5.5.
Should I just download a free convertor and convert to mp4 or wmv or are there any other options to import it into CS5.5? If anyone can recommend a free convertor I would be grateful.
Thx

Scorm pkg made up of number of FLV files takes time to load in LMS

Hi everyone,
I m creating the scorm packages in captivate. The source, i have received in MP4 format which I am converting into FLV files. I have loaded these FLV files on to slides in captivate. This way I am creating the scorm package using scorm 1.2 settings.
Problem: I have loaded the scorm package to LMS and tested it. It takes longer to load the files than the usual time. Can I reduce this time frame somehow? I know video needs a buffering time, but if there's any way to reduce this time - it would be a great help.
Pls help..
Thanks & regards
Vikas

Hi Vikas,
The time it is taking is because of the size of the project and the load on the bandwidth at your end.
Basically, you need to reduce the size of your package. So, to do that encode your FLV videos to a smaller size using Adobe Media Encoder. And then add them to the slide again and re-publish the SCORM package.
Tip : While Encoding, Keep the level as Baseline or Low and Target Bitrate as least as possible, it would display your the expected file size at the below, when you use custom encoding settings.
Good Luck.

How do I convert my .fla file to a .flv file?

I guess the subject says it all. What I am trying to do is
"insert>media>flash video" and it appears the only extension
it will accept is .flv.

Well, Flash originally did not produce video. It's a vector
based application which
creates small size internet content. What it does tho, due to
popular user demand, is
allowing us to create Flash based video compatible file
format, out of some other video
source, which we can then be run within SWF file w/o the need
of implementing other browser
based players.
Imagine if Flash was actually capable of producing video, all
the tools it would require,
editing abilities etc... and all possible export settings
etc... every one would have different
idea of what kind of video you could output. This would
defeat the purpose of buying After Effects
or Adobe Premiere. And yet it wouldn't be fully video
dedicated tool so all of use would complain
about the lack of some kind of features here or there. Best
if the video is done else where and
Flash only converts it to FLV. Adobe just want to protect
other applications and not to worry about
pleasing everyone.
They have enough of trouble trying to move Flash back into
Animators market because the last two
versions are very programmers oriented, with very minor, if
any, improvement on the timeline
animation. CS4 is the first in long time that has some new
stuff like Bones (kinetics) , 3d transforms
etc...
Does it make sense? I might not phrase too well what's in my
head but it make sense to me :)

Embedding flv file

I want to embed a flv video file into a html page. The flv
file is approx. 40MB. I embed the video using the insert > media
> flash video command in Dreamweaver CS3. Everything works fine,
but: As soon as the page is loaded in a browser, it starts
downloading the flv-file, although the autoplay parameter is set to
false. Needless to say that this gives problems with my limited
bandwidt (2GB/mo). How can I prevent the page from downloading the
video as long the user did not clicked the 'play' button. Any other
tips to make this page bandwidth-friendly?
regards,
Peter, Belgium.

You need to use the flv play back component to load the flv.
Open a new flash doc, open the Components window, and drag a
FLVPlayback
component onto the stage. In the Component Inspector window,
there will be prameters for auto play, and the content path which
you set to the flv name. Once you do that, it will auto size to
hold the video. Size your stage accordingly. The swf you publish
will load the flv.
When you use a swf to load the flv, it will be streamed and
will not have to download.

Videoplayback.flv file downloaded from YouTube video via Safari will not play

Hello All,
Here is my question to you:
Has Safari been altered in such a manner as to NOT allow you to download videos direct from YouTube to your Mac without some intermediary interface?
Here are the steps I would use to download the source .flv video file from a video on YouTube to save it on my MacBook Pro:
1. Open Safari.
2. Go to http://www.youtube.com.
3. Enter name of video to view/download in the search bar and hit 'enter'.
4. Start video.
5. While video is playing:
A) Click on 'Window' in Safari's menu bar at the top of the screen.
B) Select 'Activity'.
6. A window will open showing data status of the video.
7. Locate the largest loading file size and wait until it is finished loading.
8. Double-click on that file size.
9. A small 'Downloads' window will appear showing file download status.
10. Navigate to your 'Downloads' folder and drag the file named 'videoplayback.flv to the desktop.
11. Double-click the aforementioned file to start the video in a suitable .flv player (I was using SWF & FLV Player originally).
This process no longer works. All I get is a black screen when I double-click the downloaded .flv file.
Notes:
The file size in Step 7 above would vary accordingly to the length of the video, but now every video I try to save as a .flv is approximately 1.7MB no matter how long the video is. Something isn't right here.
I had originally downloaded and used SWF & FLV Player to view my video when the above process used to work, but now it has upgraded itself to Elmedia Player and wants me to upgrade to the PRO edition to be able to download videos from YouTube.
Any insight to this will be greatly appreciated!
Thanks in advance for reading and responding to my question!
Sincerely,
- Austin C.

Thank you for your timely response and suggestion, Mr. Davis!
I did exactly as you said, made sure there was NO trace of the Elmedia player anywhere on my machine after the uninstallation procedure, but unfortunately this did not work.
When I dropped the videoplayback.flv file into the VLC player, I get this error message:
There is something deeper going on within Safari, I believe. The fact that different length videos on YouTube all yield the same 1.7MB file size when I try to download them is puzzling.
Thoughts?

Making a .flv file and retaining quality

I have a completely finished movie in Final Cut. I need to create a .flv version that is really small in file size (less than 10mb) but retain the quality.
What is the best way to do this?
I have a friend who had a quality .mov file of 18 mb that was converted in to a .flv file of 4.6 mb and it still looks amazing.
Any help would be much appreciated
Tim

There is no magic button that will work for all videos. A lot depends on how many pixels are changing between frames and this can be drastically affected by long, slow dissolves - particularly if dissolving between motion-intensive scenes. And, of course, quality is a subjective term that must be ironed out with several review steps with you/your client.
That said, I've been very happy with results I've gotten from Sorenson Squeeze (and similar products) from Sorenson Media over the years.
http://sorensonmedia.com/
Its interface offers quite a lot for tweaking the quality/size of the output files.

FLV File does not play when published to my web server

Hi. I have created a short video in VC3 and selected the FLV option to create a web page. When I uploaded the entire file content to my web server (windows 2003 server hosted at Network Solutions) the FLV file will not play. Now... if I do the same with a WMV tile, the video plays.
You can view the file at
http://www.airforcehomeseller.com/videos/va_education/VATutorials/index.htm
We have another video published in WMV format, although the video vs audio sync is out of wack at the moment, at
http://www.airforcehomeseller.com/videos/Energy%20Pricing%20101/index.htm
What am I doing wrong?
Any help would be greatly appreciated.

Hi again
You should probably double-check to ensure the standard.js file was also copied in when the HTML page was imported. It should be there but it never hurts to double check.
You might also perform a double-check to ensure things ended up in the correct folder (if you are organizing your project into folders). It could be that you moved the HTML page into a different folder and orphaned the JavaScript file.
Cheers... Rick

How do I convert an flv file to still images?

This may sound stupid, but I have a downloaded flv file, and I want to use about
8 seconds to make still images so I can trace into Illustrator and then export it into Flash. (both are older versions).
Is this possible?
It is for an animinated logo.
Thanx.

Using a FLV file in Flash for Web Graphic

Hello thank you for looking in.
I made a FLV file in After effects. 5 seconds long. I would like to convert it (So I think) in Flash so I can park it on my website for some 'eye candy' I was able to import the FLV an After Effects creation exported as an Alpha FLV.
I import it to the stage, have a few options about players when doing so. I used the stand alone Player option when opening my sequence. I prewview it and it works fine using both Browser and Player mode when previewing movie. However, I am unsure how to make that file play or loop forever? I am unsure of exporting it so I can just upload it to my Wordpress site and stuff it in my header so it plays when a browser opens that page. I know that is a tall order to ask. If you could either direct me to a link to the proper steps I would need to learn I would appreciate it.
Thanks in advance for any direction on this one. I have created a flash poject or two and exported them as swf and have had them work, but I have never used an imported FLV is there any diff? And how come it does not automatically loop without the ACTION ()Stop ?

I was able to get my FLV FLASH to Loop, must have been a glich on my end. Closed it and reopened it and it reverted back to a loop. I am still wondering, or I forgot the steps to exporting my work with JS ? I cannot remember where I found that info, nor how I did it. As of now I turn on JS toolbox and my Html export is a white box....I would love to export as no background, or Alpha and have the JScode export so all I need to do is cut and paste into my HTML page and change the upload address or A href " " Steps...Anyone? Thanks
BTW I was able to export my AE file as a SWF however all the cool stuff that made the eye candy was not supported like fill over stroke or 3d when exporting out of AE direct as a SWF with LOOP. FWIW
