SWF Compression

Hi,
I was wondering if someone could help me with what I think is
a swf compression error.
I created an animation in Flash MX using a large Jpeg
background and smaller gif objects. The Jpeg moves at times, as if
a camera is panning accross a scenery while most times the gif
objects are stationary or move off the screen. The animation is a
total of 7 scenes. However when I convert the animation to a .swf,
the background at times becomes blurry and smeared (like a gradient
or horizontal lines) even though the background is stationary in
that part of the scene and only the foreground gif objects are
moving. Other scenes the background pans correctly in the SWF and
everything looks fine in the original Flash MX file.
My question is, is this an error caused by Flash MX or SWF
compression? Is there anything I can do to correct this and has it
happened to anyone else?
I can post the animation on my website if anyone wants to see
the error.

Flash .. turn on the compression option on output. I'm pretty
sure free
tools like FLASM will also do the compression for you.
If that is already one, try reducing the size of your images,
the quality of
your sounds etc, the number of embedded fonts you use, if you
have complex
vector drawings, try drawing them smaller and then scale them
bigger.

SWF compression issues

I'm using Flash MX 04 Pro and am having issues with SWF
compression when compiling.
I have two .FLA which last week compiled to 52k and 83k.
Today they're compiling to 102k and 172k respectively!!!
I have not made any changes to the files, publish settings,
or general Flash settings whatsoever?
Any ideas why this is happening? Rather urgent as I have
things that need to go live this afternoon.
Thanks in advance!

Alright I take that back. While the compression does make the compiled SWF file a lot smaller, when trying to load time image data I keep getting invalid data errors:
Error: Error #2136: The SWF file file:///app.swf/[[DYNAMIC]]/24 contains invalid data.
at flash.display::BitmapData/ctor()
at flash.display::BitmapData()
Anyone know what's going on?
EDIT: I figured it out. Apparently you can't use smoothing when you're using compression or it will crash. That's it. Just remove the smoothing="true" tag and it will load fine. Would've been nice if that was in the documentation somewhere...

Compiled SWF compression issues

I've written some code that generates .as files with embedded image assets then compiles them all into a SWF file so I can easily automate generating asset SWFs, but after comparing the size of the SWF to the size of one generated from publishing an FLA file with the same assets it's a LOT larger. Does publishing from an FLA apply some type of compression that using mxmlc does not? Is there any way to get this outside of using FLAs because have 100s of FLA files is a really horrible option, hence why I bothered doing all of this. Any help would be greatly appreciated, thanks!

Program to compress swf file?

hey there,
so i have a rather large swf file that is having trouble
loading...it takes about 10-15 seconds to actually start to load so
i've come to the conclusion that i need the help of a swf
compression program but i'm wondering if anyone can give me advice
on a reliable program to use? have any of you had a similar problem
and used a good program to compress?
let me know thanks so much!!

I don't know of any programs that compress, but I can give
you a few tips.
1) Under your publish settings, make sure that "compress
movie" is checked.
2) If you are not doing so, use 90% jpg compression on your
bitmaps, as opposed to 100% or default. It doesnt seem like a big
change, but it makes a world of difference.
3) Under publish settings > flash tab > options
section, click "generate size report". Then when you publish, you
will get a size breakdown of everything in your file and you can
easily pinpoint where the majority of your file size is coming
from. Then you can make adjustments accordingly.
Hope this helps,

Audio Settings are ignored on export to SWF in Captivate 4. Advice?

Background: Project is a 1-hour, spoken-word PowerPoint slide presentation, about 60 slides, about 1 min each. Audio has been split into one CD-quality, mono .wav file for import to each slide. All clips are excerpts from the same, full-length .wav file. Nothing fancy, no captions, animations, etc. Just one dog and one pony in this show. Using fully updated version of Captivate 4.
Problem: Upon export to SWF, any changes I make to the audio quality settings do not take. That is, I still get a huge SWF file with full CD quality sound. SWF file size is ~47MB. Should be closer to ~25MB or even less at my target quality of 11kHz, 24kbps.
What I've tried: I have adjusted both the Audio Settings for the project, as well as the SWF Size and Quality settings (in the Preferences dialog box, Project category) by alternately selecting "Low" or unchecking the "Retain slide quality settings" box, then synchronizing the settings with the settings in the Audio Settings. I have also tried selecting and unselecting all SWF compression options.
I have tested this on two computers, one XP Pro, the other Vista Home Premium 64-bit. Both Captivate installations are fully updated. Same results on both.
Things that make me go "Hmm": I can create a Captivate project with one slide as a test and achieve full flexibility of audio kHz and kbps upon export to SWF; that is, it works just like I want. However, as soon as I add a second slide, my export quality reverts to full CD-quality. I've even tried this with an extremely simple project with no PowerPoint slide, no skin, just blank white slides. So, I do not think it is an issue connected to some other aspect of the project in question.
So... Is this a bug? The odd thing is that this process has worked in the past. It seems that it has suddenly become a problem. If it were on only one computer, I would reinstall, but given the same outcome on two very different computers, it seems very unlikely that the same quirk has materialized in both.
Advice? Thanks. -Steve

Hi Steve,
This is a long shot, but you could try copying and pasting all of your slides into a new instance of Captivate. If you have specified certain audio settings Captivate should pick these up when you export. If not then it is possible that your CP file has become corrupted.
If that doesn't work, please file a bug report using the web address I have included below.
Adobe Captivate Feature Request/Bug Report Form
It would be interesting to see if the CP team can shed any light on why this is happening.

Video breaking up in MP4 and SWF output

Hi,
I just started having a new problem in Captivate 6 (64 bit) output. I do final output to MP4, but output to SWF while I am testing. The problem has appeard in both.
The video breaks up in certain places, and I see random colors, blocks, and partial after images from previous slides.
I first saw this last week after getting a fatal error that caused Captivate to shut down. The error came when I tried to convert typing to a text animation. I assumed the video problem was due to file corruption affecting certain slides. I was able to fix it by replacing these slides and the output looked okay.
Today, I saw the same issue appear in an MP4 generated by a different Captivate project. I set the Preferences > 'SWF size and Quality' to High and removed the SWF compression. This improved but did not fix the problem.
I thought it might be my video driver, so I copied the project to a different computer (computer 2) and re-published it. The MP4 looked fine. I then viewed the new MP4 on the original computer (computer 1) and again, it shows clean. I tried viewing the problem MP4 on computer 2, and it ALSO looks fine.
I don't think it's the video driver on computer 1, since I haven't seen the issue with other MP4 that I am testing randomly. Is it possible the Captive instance on computer 1 is corrupted? Should I reinstall it? Other thoughts?
Thanks very much.

Review and publishing freezing

I have a project which consists of 180 slides. When I
attempted to review the project in its entirety, on the "generating
slides" dialog box, captivate froze. Subsequently, after checking
the forums regarding the performance issues, I discovered this
project should be broken down into smaller projects. I have since
done so. Now, when I've attempted to review or publish one of the
smaller projects (now 40 slides), Captivate still freezes on the
"generating slides" box. I cannot reivew nor publish this project.
Help!

Additional information:
I can perform a preview of the next 5 slides; however, I
cannot perform a preview "from this slide" from any slide - it
freezes. It is not a memory issue as I can preview and publish
other projects that I have created (much larger ones). I have tried
to take the SWF compression preference off, which will not allow me
to preview at all (not even the next 5 slides), so that is not an
option.
Any ideas?

Flash movies won't play in document or browser

Hi there,
I am having problems with putting flash movies onto my website. I know this is a common problem so apologies for any repetition.
I have trawled through a lot of forums trying to solve this issue and so far have not found a solution that works for me.
First of all I'm using dreamweaver v7, on a macbook OSX (intel)
On inserting flash movie, only the box with 'f' apears in the document, and in browser, nothing at all. It doesn't worry me so much that the movie doesn't appear in the doc, as with shockwave it's the same. However shockwaves play fine in browser.
I have tried the following so far:
- moved the movie .flv file to the same folder as the html document that it relates to
- made the file name really, really simple. 6 letters and no other characters.
- tested in alternative browsers
- tried inserting another flash object (flash button) to see whether the problem resides in inserting flash objects, or if the problem is with the movie file itself (the flash button worked, so I thought the movie file must be the problem) - so then ...
- I tried compressing the movie in a different programme - I tried sorenson squeeze - still nothing
- As inserting the movie as a quicktime works fine using 'insert shockwave', I even tried changing the file extension of the QT version from .mov to .swf as I read somewhere that it might work (!!!??) but it didn't though the movie still played without dreamweaver
So, I reach the conclusion that the movie is not after all the problem - but what is? since inserting other flash objects does work?
Very confused! Thank you for any help offered.... Laura

I am a bit confused though - is flash video not the same as flash movie?
No. Flash refers to its files as movie files. FLA (editable) and SWF (compressed for Web) are Flash movies - not to be confused with cinema. FLV files are Flash Video files.
Just to confuse matters some, just prior to the creation of the .flv format, it was not uncommon to import videos into Flash and save them as .swf movies (videos). But that was only good for very short, very small videos.
Additionally, since you brought it up, Shockwave files are also referred to as movies. But they are created by Director, not Flash. Director, like Flash, refers to its files as movie files. DIR is the editable file and DCR is the Shockwave-compressed file for the Web. The Shockwave plugin is not the same as the Shockwave Flash plugin. Shockwave Flash cannot play Shockwave movies, but Shockwave movies can play Flash .swf movies - neither of which are videos.
How's that for clear as mud?

How do I make the mp4 file a little smaller?

I've created some films and I need to get them under 10mb. They are only slightly bigger than this at the moment.
Any suggestions on what I need to do in the publish settings to make them a little smaller?

Hello Rhian,
Welcome to Adobe Forums!
You can check the Compress SWF file and Advanced SWF compression option from the SWF size and quality under the EDIT> Prefrences menu before publishing.
This will reduce the size but will also reduce the quality as well.
Thanks and Regards

Captivate 3 freezing when publishing- help?

Hi,
I’ve reached the end of my tether and was hoping someone could help me out with some professional Captivate insight.
I have had a good look around this forum and tried several things
-          I have unchecked the advanced project compression option (still froze)
-          I have unchecked this AND the compress compiled SWF file (when I’ve done both it has published but published a blank presentation)
-          I have removed the borders on the slides
-      I have saved the audio and slides on to my C drive (and not on my network) and used them from there
I am using Captivate 3 to make a number of lectures available on my company’s website. This involves importing slides from Power Point, matching them with the audio recording of the lecture and publishing them on Flash 8.
I have a new pc with 132 GB of free space however recently any project I am attempting to publish freezes during the publishing stage- during the swf compression. In the past this has worked fine- although I was mostly publishing 2 hour lectures (but one or two 3 hour lectures published successfully) and now I am only publishing 3 hour ones.
To give an example currently I am attempting to publish a lecture with 57 slides. These are non animated slides, only containing text and bullet points. However they are on my company’s heavily branded template and therefore are 1.93 MB in size. Thinking this was the problem I put the slides on a blank template and just included a logo, cutting them down to 300 KB in size- still it froze when publishing. When beginning a project I will
-          Import slides from Power Point
-          Import them as Background Image
-          Advance slides automatically
Then I will import the audio, which admittedly is very large at just shy of 3 hours in length and 157 MB in size. I will then click the distribute audio over several slides option and do that manually in accordance with the lecture. When I publish I choose flash player 8 and the audio settings are MP3, 64 kpbs, 44.10 KHz
Is I just that the audio is too large or does anyone have any other ideas?
I would be very grateful for any help

Hi there
Wow, I would think 3 hours of audio would gag Captivate big time. Most of the Captivate movies I've ever seen or dealt with were perhaps five minutes long if that.
Are you able to perhaps slice and dice the audio? My thought here is that if you really need three hours of audio, perhaps you break the three hour clip in to smaller segments. This would reduce the size of each project and perhaps help you be more successful. Maybe slice a three hour audio clip into six segments of 30 minutes each. Then see if your publishing is more successful working with smaller segments. If so, you could then Daisy Chain the projects together to achieve a seamless transfer where as one segment finishes, the next loads up and plays.

Hopefully this was helpful to you... Rick

Audio stuttering problems with certain exported MP4 files

I'm currently running Captivate 6.1.0.319 on my old and decrepit Pentium 4 machine that has 4GB of RAM and is running Windows 7 SP1. I'm developing an online training course on RoboHelp 10 for Udemy, and they require all lecture files to be in MP4 format. Unfortunately, some of the MP4 files I generate from Captivate have audio stuttering starting a few seconds into the generated video and nothing I try fixes the problem.
All the videos are being recorded with video dimensions of 1360 x 978 pixels. I import the .cptc file I recorded into the .cptx file, and then I import an MP4 audio file into the .cptx file. When I finish editing the .cptx file, I publish it to an MP4 file using the highest video settings and the highest variable bitrate audio settings.
I have tried the following to try to fix the problem:
Turned off SWF compression.
Created a new .cptx file and copied the slide from the problem .cptx file into the new one, and published that new .cptx file.
Disabled all software operating in the foreground and the background.
Tried generating the MP4 file on my laptop; the laptop runs the same version of Captivate on Windows 8.
As I said, Captivate generates some MP4 files perfectly without any stuttering, and others have the stuttering problem. If this problem sounds familiar, it's because I wrote a couple of messages about this a few months ago and despite some good suggestions, I wasn't able to solve the problem. I've spent my time during the past few months trying to find another program that will convert SWF files to one of the formats Udemy supports -- MP4, MOV, or FLV -- without success. Captivate exports to SWF and HTML5 format files without any trouble at all. But MP4 generation is spotty and I need to get this resolved so I can get this project off my plate and start making money off it.
If you have any further questions, please let me know. I look forward to hearing your suggestions.
Thanks,
Eric Butow

Hi,
I am having the same issue and cannot figure out what is causing it, as it occurs randomly - but fairly frequently - when I publish to mp4. And it is not tied to the project - seems to be something happening during the publishing. The issue might occur one time when pubishing a project and if republished again it may or may not occur again. I would be very interested in finding exactly what is causing this and any step that are tested and proven for getting away from the problem.

Blurry output from Captivate 5

Hi again guys, im having trouble with my latest project in Captivate 5. Project contains lots of text but after publishing everything is blurry :-/
Quality of output is set to HIGH and no SWF compression is enabled. Some ideas?

Another problem is that, when i try to open published project with *.htm file it will open only blank page (tested in IE,Chrome,Opera).

Error msg: Insufficient memory to compress SWF

When I publish SWF, export to HTML being the only checkbox checked, I get an error message: Your computer does not have sufficient memory resources to compress the SWF file. I am using Captivate V 4 (trial) on a fairly new PC, with 3.25 GB of RAM. The SWF cmpletes after I OK the error msg. SWF file is only 12,295 KB, and it seems to run fine. What could be causing this message? I don't really know if the final SWF is compressed or not.

Did you get a result? I am in the same boat. I have licensed 3, but witht he Capitate 4 trial I needed a way to export to PDF or get the content into a forum suitable to post (like a video) and my session is 18 minutes long - full motion capture (I know, I know). So my PDF is 123 meg. but I get the same crap out message. And I really do think it should come in at a much smaller size (Captivate 3 returns about 45 meg of similar quality for about 12 minutes). And I have 4 gig on my Dell (3.6 Gig addressable).

Why can't Flash CC compress a SWF as well as Flash CS 5.5?

Does anyone out here know why this happened?
I have a FLA file from which I needed to export out a SWF no larger than 40kb. Without changing any of the settings, the SWF exported out as 63kb. So I opened up the FLA in Flash CC and went to Publish Settings. Tried changing the JPG Quality, clicked Compress Movie (Deflate), removed the Include Hidden Layers checkmark. When this wasn't enough, I tried compressing each image in the Library by going to each one's Properties. After playing with the image quality for awhile, the smallest I could compress the SWF file was 58kbs.
But then... I tried opening the same FLA in Flash CS5.5. Used the default Publish settings. Did not change the file whatsoever. And the exported SWF was 35kb! Plus the image quality was a heck of a lot better than the 58kbs SWF exported out by Flash CC.
Any ideas why? Does CC add anything to the file that 5.5 didn't? I'm just finding this whole thing odd and annoying to work with when the file size requirements for flash banner ads are still only 40kbs...
Thanks for any insight!

Yeah - this does make sense.
In Flash CC, I was targeting Flash Player 11.7.
In CS5.5, I was targeting Flash Player 10.2 -- which does not even seem to be available in CC anymore.
Buuut -- I just did a test using Player 10.3 in CC and that got the file down to 45kbs.
So this is great to know! Thanks!

How can we compress SWF files and optimize tool?

I need to reduce SWF file size up to 70%, quality will not be sink.
Is this possible in adobe software? please help...

Iam working on banner production, is their any better software/tools for SWF optimization/compression?
I got one SWF and FLA from other creative team, SWF size is below 50 KB look's better quality, I have changed some small amends, when i was exporting it from FLA... the SWF file weight goes to 90KB, i compressed image quality then, expoted again... the file size goes to 70KB. how can i do 50KB in better quality.
Thank you for your help!
