Encoding flv video

I use FCE to edit video. I then convert the video to flv for delivery (viewing) via the Internet. I've read lots of discussion on how to create the flv. I've tried various methods, including:
1) Since I have Flash installed on my computer, I've used FCE's Quicktime conversion to export/encode directly to flv, and
2) Export an uncompressed QT movie from FCE; then used Flash Video Encoder to convert the .mov to .flv
What's best practice (I'm open to other procedures too)?

Thank you.

Best setting for encoding flv video?

What is the best, most universally accepted setting for encoding flv videos to be viewed over cable modem access?

I completely understand.
For print work, I did a lot of that with either Save_As, or Save_As_a_Copy in Photoshop. Then, they added Layer Comps, and that cut down on the work, but allowed me to have several "treatments."
Have not used that in PrPro though. I see the usefulness of the feature though.
Yeah, clients are fond of saying, "really appreciate you following all of my ideas, but I think I like what you had last week better... Can we go with it, but with these few extra changes?" Happens all too frequently. Lot easier now, than back in the old days, when one painted the cyc, set up the shot, and lit it, only to have the AD change the color of the cyc. When done, they'd often say, "liked that original color better. Let's tear it all down and re-paint to that." Now, I just change the color of the background digitally - a lot less painting!!!"
Thanks for that tip,

Cap 7: project with an .flv video goes to Media Encoder

I have a Cap 7 project that includes a slide with an .flv video embedded. When I try to publish as both .swf and HTML5, the Adobe Media Encoder appears. I have no idea what to do with the encoder, if anything, and the publish process just stalls. Is the .flv video the issue? There is a note in the Cap 7 "publish project as HTML5" help that states that .flv files that are created using On2VP6 codec only are supported in the HTML5 output. Am I missing something?

FIXED!
Thanks to some points in this thread, I have solved my problem.
It was the KNOLL LIGHT FACTORY plug-in. I removed it, and the Adobe Media Encoder now works on my system. I assume that DYNAMIC LINKING between the CS4 apps also now works, but have yet to test that.
This also explains why my CS4 suite works on my MacBook Pro; I never installed KLF on my laptop.
Now I need to tell RED GIANT SOFTWARE about this problem, and either get a solution from them, or a refund.
Thanks. You can add this solution to your collective repertoires in case a future OSX user encounters this exact problem.

Flv video created with flash 8 video encoder

anyone know why flv files that I've created using the flash 8
video encoder don't seem to have any metadata in them? or maybe
they do but they never kick off the NetStream.onMetadata event so I
can't read it...
Similarly if I use the 'import video' function of Flash Pro 8
I get the same issue - yet FLV video created using Sorenson Squeeze
works fine, so I'm fairly confident that my code is OK.
Even more bizarrely, if I use the FLVPlayback component that
ships with Flash 8, that seems to read in the metadata OK!
argh!
Just to confuse things even more, the flash help for
NetStream.onMetadata says: "The Flash Video Exporter utility
(version
1.1 or greater) embeds a video's duration [...] into the
video file itself."
As far as I can tell I've got version 1.0 of the flash video
encoder/exporter but I'm damned if I can find out where to get an
update from...! Ever since CS3 came out it's been harder and harder
to get hold of stuff about flash 8 on the Adobe site...

well that's the thing - the metadata never traces out if the
video was encoded with flash video encoder, but that code would
work fine with video encoded with sorenson squeeze.
think I have worked it out now though: in order to pause the
video at start I am calling NetStream.seek(0) when I receive
"NetStream.play.start".
For some reason when I do this with flvs encoded using flash
video encoder, it stops the onMetaData event from firing - but
works fine with other flvs! weird... shall have to find another way
of pausing the video at the start I guess.
thanks for the reply though

Embedding FLV Video Into PDF Files

I have been testing out embedding FLV files into PDF's to simplify presentations (no need for Powerpoint, DVD player, DVD player software, etc..). It is a bit slow when a big video file will load, but I think it is worth it for the simplified presentation method.
My problem is this, whenever I embed an FLV file into a PDF, it seems to degrade the quality down a notch or two. I am not concerned about file size since these will always be played locally from a hard drive or CD so I created the embedded FLV file to be high quality and very crisp (720 x 486, ~2200kbs bit rate). However, no matter how good a file I embed, after it becomes embedded it always looks worse. At this point, it has mainly been trial and error, but the original quality does not seem to matter as to how it will look in the PDF.
Does Acrobat Pro re-encode the video no matter if it is FLV or not? And is there anyway to change the settings so it does not alter the existing quality?
Thank you.

Are you inserting a screen capture FLV of the whole screen. I use camtasia Studio to capture my desktop in video... and if the playback is NOT at the same size as the original...then it can look blurry.

.flv VIDEOS not playing smoothly

A heavy video-generated Captivate project has been created in Cap 4:
* 18 slides all up, with the total size of .flv videos coming to 90.7MB
* Using Captivate, as looking for interactivity -- there is also a menu, so users can jump to whichever section they'd like to watch/use
When accessing the completed project online:
1) The loader quickly goes up to 100%
2) Shows the preloader image I have inserted
3) User clicks play, and the first slide with video plays...
The first video either freezes / move quickly along the timeline. You are also unable to jump to other sections shown in the menu. While I am not too worried about this, my priority is for comfortable viewing for the first video. I am assuming that the first video freezes, etc because the whole project has yet to load completely. How can one work towards this solution? I have tested the loading time, changing it from 10%, 20%, towards 100% but the video is still freezing at times / moving quickly along the timeline.

Thanks for your PM - I just checked your project and it runs 100% fine and smooth for me.
I checked it on two different PC's
1. Vista 64-bit, IE 7.0, Flash player 10, 10mbit/10mbit internet connection.
2. Win XP Pro, IE 7.0, Flash player 10, corporate LAN
This leads me to the conclusion that the issue is the speed of your internet connection. The first video is around 80 seconds and is 13.5 Mb. That is very big when you consider the length and especially the dimension of the video you are using.
If you dont already have FP10 then try and upgrade to see if that helps. It's much better at handling videos etc. than the older versions of Flash players.
Secondly you need to recode your videos. You will be able to get the first video down from 13.5 to perhaps 4-6 mb, with a noticable quality loss. If you have Flash you can use the Adobe Media Encoder to do the recoding.

FLV colorspace is different from Android to Android? Is FLV video HW accelerated?

I'm not sure how long this problem has been there, maybe since November 2012 when we launched the app, or did it just appear. I can dig deeper if I get any replies. It seems some of our FLV videos, which have a person speaking on front of a white (as in #ffffff) background, end up having gray background in some devices. I had a lot of trouble originally getting the encoding process work and I'm not sure if I even understood it in the end.
Videos have different color spaces, one having RGB values from 0-255 and others from 16-235 for example. The color space information is encoded in the video, which video playback software may use or not. In the end, videos look different with different playback software and hardware combinations.
I've trusted FLV, because I thought Adobe AIR does everything by software and thus it should work (and has worked) exactly the same on all devices. But not any more. The only thing I can think of, is that some parts of video playback is HW accelerated. Is it possible that my Galaxy Tab 10.1, which shows all videos correctly, doesn't use HW to render video, whereas Galaxy Tab 3, which shows some videos incorrectly, uses HW? It may also be, that some of our videos indeed have wrong color space information in them, a bug in our encoding process. But I need to understand how AIR works a bit better to get the problem solved.
We're using a complex command line script, involving Avisynth. The line I underlined may not have always contained ".ConvertToRGB().ConvertToYV12(matrix="pc.601")" part, which could be the problem, but not explain why this happens sometimes and on some devices.

Hi BKSTER
I just tested this and it seems to work fine. Here is what I
did.
1. Within my Captivate project, I inserted the Flash .FLV
file.
2. I browsed to a file on my hard drive and the File Link
field listed the absolute path of C:\somefolder... blah blah blah.
3. I then changed it to point explicitly at the server where
I placed the .FLV. The link then looked like this:
http://www.MySever.com/FileName.FLV.
4. I dismissed the dialog and published the Captivate
project.
5. I uploaded the Captivate files to one server and the .FLV
on the other.
6. I ran the Captivate .HTM file and observed. The .FLV
played as expected!
Hope this helps... Rick

How to embed Flash .flv video?

Hello guys,
I am wondering, is there any way how to embed Flash video onto my web page?
And regarding QT video template on iWeb's Movie page, can I drag any kind of QT ? Like H.264 QT for example, or is it just for Mpeg2 QT?
Thank you so much for any advise.

What is your video codec you are working with? NTSC (and PAL) DV is about 13 gigs/hr uncompressed. When you export your QT movie from your editing application and convert the file to flv you are compressing the video at that time with a determined bit rate and video dimension. quality and file size comes down to math. File size = bit rate x movie length. Quality is bit rate in relation to dimension. Surprisingly enough the recommended video encoder for flv is Flash Video Encoder application that comes with Flash. Sorenson Squeeze is arguably the best flv video encoder. Visual Hub is not recommended if quality and efficiency is desired. Flash Player is a browser plug-in that that allows web visitors to view Flash videos on your website from their web browse. Most already have Flash player installed and you can insert a script that checks to see if the visitor has Flash player installed and if it doesn't a window will appear informing the visitor that they are required to instal the Flash Player in order to view Flash content on your website. A URL is also provided to direct the visitor to the Flash Player download page. Insert this script into the <head></head> of your site:
<script type="text/javascript">
function MM_CheckFlashVersion(reqVerStr,msg){
with(navigator){
var isIE = (appVersion.indexOf("MSIE") != -1 && userAgent.indexOf("Opera") == -1);
var isWin = (appVersion.toLowerCase().indexOf("win") != -1);
if (!isIE || !isWin){
var flashVer = -1;
if (plugins && plugins.length > 0){
var desc = plugins["Shockwave Flash"] ? plugins["Shockwave Flash"].description : "";
desc = plugins["Shockwave Flash 2.0"] ? plugins["Shockwave Flash 2.0"].description : desc;
if (desc == "") flashVer = -1;
else{
var descArr = desc.split(" ");
var tempArrMajor = descArr[2].split(".");
var verMajor = tempArrMajor[0];
var tempArrMinor = (descArr[3] != "") ? descArr[3].split("r") : descArr[4].split("r");
var verMinor = (tempArrMinor[1] > 0) ? tempArrMinor[1] : 0;
flashVer = parseFloat(verMajor + "." + verMinor);
// WebTV has Flash Player 4 or lower -- too low for video
else if (userAgent.toLowerCase().indexOf("webtv") != -1) flashVer = 4.0;
var verArr = reqVerStr.split(",");
var reqVer = parseFloat(verArr[0] + "." + verArr[2]);
if (flashVer < reqVer){
if (confirm(msg))
window.location = "http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash";
</script>
Then replace <body> with this:
<body onload="MM_CheckFlashVersion('9,0,0,0','Content on this site requires the latest version of Adobe Flash Player. Do you want to download it now?');">
Beginning with Flash Player 9 h.264 QT movies are now supported for playback. Simply change the file extension from .m4v to .flv to convert the h.264 video to Flash video that can be viewed from Flash Player 9+ on a web browser.
hope that helps!

Encoder Audio/Video Not Matching Up

I am trying to encode a 1 hour MPEG2 video file to FLV. I
have used different computers (upgrade to faster processor, 1GB
ram, but this was on a completely separate machine from previous
attempts) and different MPEG2 codecs. Every time I encode a video
the audio and video tracks do not line up. They are about 3-5
seconds away from each other. I have verified that the original
file is correct. Please advise.

Their problem is they have video at 48 kHz and audio at 44.1 kHz<<</div>
Ummm No. Video isn't measured in audio sampling rates. You probably captured video with the preset for DV NTSC 48khz (the 48khz is the audio portion). But your audio was either recorded incorrectly or from another source (CD audio perhaps?).
Use QT Pro to export the 44.1khz audio to 48 khz and import into your project - OR - use SoundTrack Pro to resample at 48khz.

Problem adding an FLV video to an actionscript 3.0 file

Hi i'm new to Flash and I’m trying to add a 20 second long FLV video to an action script 3.0 file in order to place an animation over this imported video. The video is my dog running around and I want to animate a sprite in a layer over the top of this to make it look as if the sprite is chasing my dog. Is this actually possible? I’ve tried importing the video into the file but the video does not play it just shows one screen capture from the video when previewed for the entire time it is playing and when I try preview the video in a window of its own it cannot load it, it just freezes when loading (the program does not crash by the loading bar freezes).
Any thoughts on where I’m going wrong or what I could try or if this idea is even do-able using flash professional CS5.5 and my laptop has over the capabilities suggested by Adobe to run the software?
Thank you!

Probably is the format in which your video is encoded, attempts to convert to another format.
You can import the video to the time line, but the problem is the synchronization, that depends of the performance of the machine.
Maybe the trick is export a flash animation (swf) and use Adobe Premiere to synchronization the video with the animation in a upper layer.

FLV video controls lock up

Hi there. I'm creating a website in Flash CS3. The FLV video
in the center of the page utilizes one of the stock video control
panels in the video encoding process
(SkinUnderPlayStopSeekMuteVol.swf) . Upon testing the movie, both
in Flash and uploaded on my server, the controls work fine for
about 10 seconds then seize up and stop being functional. The page
is simple as can be. 1 frame long, a couple pieces of text, a
static background and the FLV in the middle. Any ideas on why the
control panel freezes up?

Have you tested on more than one machine? Perhaps you could
post a url and we can see if it's a machine issue? I've never had
an flv cause a lockup, I'd be interested in seeing this.

FLV Video - Alpha Layer Not Working

Hi I have a strange problem. I am trying to encode a AVI
video into a FLV flash video which includes an alpha layer. These
are the steps I have taken as follows:
1. Created animation in photoshop, saved as PNG files.
Imported files into Flash, and the alpha works great (but the size
is too large, so I switched to embedded FLV video).
2. Took PNG files and imported then in Premiere Pro 2 and
exported the video with the 32-bit Cinepak Radius codec, with a
million colors. (I don't know if its 32-bit, as it says it no where
in the export options).
3. Encode the AVI with Flash CS3 Video Encoder, using On2 VP6
codec with Encode Alpha Channel enabled.
Result, either the clip is completely black or the video
doesn't have an alpha channel when imported into Flash. I am
thinking the clips that are completely black are the AVIs that had
an alpha channel.
Below is the AVI clip, if anyone can tell me if it has an
alpha channel by encoding it to a FLV video OR can offer any help,
thank you.

PS. I have searched the internet for hours for related info
or similar problems, but have not encountered a solution. I have
even downloaded Sorenson Squeeze and have tried multiple
codecs.

You set your texture environment mode to GL_REPLACE. The implementation of this feature is to replace the primary color (set via ColorPointer or Color3f) with the sampled texture value, so your color will have no effect.
Replace the texture env mode with GL_MODULATE, which will multiply the Texture Unit Input Color (==PrimaryColor for Texture Unit 1) with the sampled texture value.

When I publish as an .mp4, the embedded .flv videos clip at the end

I am using Captivate 6.0.1.240. I have .flv videos that were encoded using Adobe Media Encoder from a .mov file. The videos are embedded on the slide, as multi-slide synchronized video, but only distributed across one slide (as strange as this might seem, it is what was recommended to me because using Event Video resulted in choppy video).
Now, the videos clip off a second or so before the end of the video. There are no transitions on the video slide or on the slide following it. I have tried extending the length of the slide beyond the length of the video, to no avail.
What am I missing? How do I get the embedded .flv videos to play fully?

Hi there,
As you told you have checked that there is no transition on the Slide on which you have the video.
Have you checked the transition effect on that video, whether Fade out only or fade in and fade out is selected. Select that multi slide video and click on the properties panel and check the transition on it.
Also, if this video is on the last slide, check the fade in and fade out on the project. (edit > Preferences > Project > start and end)
Thanks.

Correct settings for flv video

I have a bunch of videos, which I exported from Premiere pro CS5.5 to mp4 files. After this I used the Media Encoder to encode those videos to flv-files. The I opened Flash pro CS5.5 > import video > publish as swf and html. Same settings in the Encoder and Flash but still only half of them work. Those sites / videos that don't work just load and load, but nothing happens. Only option I have so is to encode them again from mp4 to flv using different settings to find ones that work. Sometimes bitrate encoding should be CBR, but sometimes it's VBR. For some videos I should encode alpha channel and for others there is no need. This is so frustrating. I'm using a whole day with this trial & error thing. It's hard for me to believe, that encoding settings should have such effect on the outcome. Could someone please help me with this one?
Example of an non-working site http://ok-opintokeskus.fi/tapahtumavideo2/jalkitoimet/jalkitoimet.html

Graficozzo
If you have 1920 x 1080 60i that 60i is not 60 frames per second but rather 60 fields per second. Consider that the same as 29.97/30 interlaced frames per second.
So, you want the Premiere Elements 11 project preset to be
NTSC
AVCHD
AVCHD HD 1080i30
but if you have 5.1 channel audio with your video instead of stereo, then you want to use the project preset
NTSC
AVCHD
AVCHD HD 1080i30 5.1 channel
When you drag your video for the first time to the Expert view Timeline, the project should set this project preset for you based on those video properties. You can check what it has set by looking at Edit Menu/Project Settings/General and the reading for Editing Mode, Timebase, and Frame Size. If it does not set the correct project preset, you can do that manually with File Menu/New/Project before you import you video into the project.
Please review the above. If you have any questions or need clarification on anything that I have written please do not hesitate to ask.
Thank you.
