Transparent alpha channel in flv not working
Bringing a raw avi file into Premiere Pro 2, I applied a
color key effect to the background to make it transparent. I then
exported it as a flv file using Adobe's Media Encoder. The video
codec was set for On2 VP6 with the "encode alpha channel" box
checked. Importing this flv file into Flash 8 using Progressive
download in the wizard, I placed the flv on layer 2 and a
background image on layer 1. When I play it, the background image
pops up, then the flv, but the background image doesn't show
through the transparent area of the flv. Any suggestions on what
I'm doing wrong?
Did you ever figure out what the fix is for your problem with
transparent video? I'm having the exact same issue and have tried
everything -- still no transparency (although my keying was done in
AE).

How to Validate Transparent Alpha Channel in .mov File?
I'm trying to create transparent flv files to embed in Abobe Captivate.
I shot and keyed some test greenscreen (yes, I have the checkerboard in the canvas) and have tried exporting it a number of ways (rendered/unrendered, recompressed all frames/not, etc, etc) and converted it to flv a number of ways (change mov to flv, encoding software), but when I embed it and play it back I have a black background.
How can I validate that my .mov file contains the alpha channel and it's transparent?
Second, when the .mov is correct, will changing .mov to .flv keep the transparent alpha channel or do I need us encoding software with a codec that supports transparent alpha, e.g., On2 V6?
I'm pulling my hair out here...Hi - To validate your exported (Animation codec, Millions of Colors+ ?) Qt movie has the alpha quickly, re-import the exported movie back into FCP and load it to the viewer with the viewer set to display checkerboard as a background.
Can't help with the rest.

Minumum sufficient commands to create PSD containing transparent alpha channel
I was recently typesetting some leaflets in InDesign under time pressure. I had a JPG file with a white background and wanted to create a PSD from it in Photoshop CS5 with an alpha channel making the background transparent.
I managed this in the end by blundering around, but the help file is no help, and the obvious way of creating a layer mask doesn't work.
I'd like to know the minimum sufficient command sequence to do it.
Suppose we've got this in Photoshop, with the bit we want already selected:
Double clicking the background layer and then clicking ADD LAYER MASK looks good, but it doesn't create an alpha channel. It actually creates a channel named "Layer 0 mask" but if you save it in a PSD and then import into InDesign it is not transparent.
There doesn't seem to be a "convert layer mask to alpha channel" command. Nor a "make alpha channel from selection" command.
There is a button at the bottom of the CHANNELS tab that's named "create new channel" and if you click it when a selection is active it does create a new layer named "Alpha 1", but unfortunately it is not the wanted mask but rather just the path of the marching ants.Yes, this does work. Don't know why it didn't for me yesterday.
There's no need to delete the background because in my example, after unlocking the padlock and adding layer mask, there's only one layer there. It does create, as I said above, an additional channel named "Layer 0 mask" which is what one would want as an alpha channel.
If I SAVE AS PSD, the box to include LAYERS is ticked and the box to include ALPHA CHANNEL is greyed out, but InDesign still treats it as transparent.
If I take the selection and SAVE SELECTION AS NEW CHANNEL, it creates a second channel looking exactly like the "Layer 0 mask" one above, but if I then SAVE AS PSD the box to include ALPHA CHANNEL is ticked. So the channel created by ADD LAYER MASK is of a different ilk than the one created by SAVE SELECTION AS NEW CHANNEL, although this is not apparent from the CHANNELS tab. Slightly confusing. -
FLV. not working in SWF within HTML page
I have created a SWF presentation which contains several videos as FLVs. The videos are uploaded to a folder on the clients server.
The exported SWF and HTML files of the presentations worked perfectly when hosted on my local machine but when sent to the client, who uploaded to their own server, the SWFs ran but would not play the FLV files within. When they changed the HTML files to HTM they worked perfectly.
However...when they embedded the pages into the content management system the use it required that the pages were reverted back to HTML, therefore the FLVs are not working again.
The 'still' frame appears where the FLV should be, but the skin and the video itself does not load.
Does anyone have any idea why this issue has occurred?
Thanks in advance.@Ned
Not sure about the folder structure of their site, to be honest they've been a nightmare client from day one so getting information like that out of them has been nigh on impossible.
The flv files are all in a folder together and these are linked from the swf with this link structure: http://www.sitename.org.uk/folder/video.flv
I'm not entirely sure how their CMS is structured. I was throwing this question out on the off chance that someone had seen a similar instance where HTML/HTM file types had affected functionality. -

Some things to check:
Did you upload Scripts folder and FLV files to the server?
Are you sure the web server has support for both FLASH and SWF Mime types (check with your host)?

White-based Alpha channel for flv export
I'm trying to export a sequence into flash (.flv) and include the alpha channel. The default alpha channel base color is black, but I need white because the black creates an outline around the object (check out www.wavereel.com to see the video I exported as an example). There is a way to change the monitor preview video to a white background for frame-by-frame previewing, but whenever it's played, it reverts back to black. How do you change it to white?
I just found this info, which may help us.
http://discussions.apple.com/thread.jspa?messageID=4791917�
which discusses using the Animation Sequence setting and likely a Compressor export as Animation codec from un-rendered timeline. -

Alpha only CGContext does not work blend mode
Hi,
I have a Alpha Only CGContext created with
col = 100;
row = 100;
maskBuffer = malloc(100 * 100);
memset(maskBuffer, 255, 100 * 100);
memset(maskBuffer, 0, 100 * 50);
maskContext = CGBitmapContextCreate (maskBuffer, col, row, 8, col, NULL, kCGImageAlphaOnly);
As you can see, the top half is transparent. Then I want to inverse it, make the bottom half transparent. I did
CGContextSetBlendMode(maskContext, kCGBlendModeSourceOut);
CGContextSetFillColorWithColor(maskContext,[UIColor whiteColor].CGColor);
CGRect rect = CGRectMake(0, 0, 100, 100);
CGContextFillRect(maskContext, rect);
I found that the whole context was set transparent. The blend mode kCGBlendModeSourceOut does not seem to work here. Anyone has the same experience?
Thanks,
ffSeems to me that you need to set the display width to be wide enough for all possible meanings in the LOV, rather than wide enough for the field itself. But I may have misunderstood the question. or misremembered the answer - it has been a while.

I have noticed a lot of posts on FLV files not showing when
using DW in CS2. I am using Leopard (10.5.1) on a Mac and i have
done everything according to the help files. I have Flash and have
used Flash encoder to encode to both Flash 7 and Flash 8 using the
the Sorensen Spark encoder as well as On2 VP6, then using the
insert Flash Movie to insert .flv file. Nothing works. Any ideas
welcome.I think you'll find that all of them are related to user
errors, however.
In your case, you would use INSERT | Media > Flash Video -
is that what
you've done?

Opacity / transparency in gradient map tool not working?
Hi *,
when selecting a gradient with transparency, e.g. neutral density in the gradient map tool (in an adjustment layer), transparency is ignored, i.e. neutral density is working like plain black - which I assume is not intended. And, I'm almost certain, the gradient map properly applied transparency earlier but I might have changed involuntarily some setting. So far, I could not find a good answer. Any ideas?
Best regards,
arnieYou want to use a Gradient Fill adjustment layer instead of Gradient Map for the Neutral Density presets

FLV not working with Flash 9 player
Ok, strange issue here. I've converted a file to FLV using
Flash 8, imported the video into Flash 8 and published it to my
site. When I try to view the video in IE (I'm on winXP by the way)
using the Flash 8 player it loads correctly and starts playing. If
I'm using Flash 9 player the video never loads. I can right click
in the area where the swf is and I get the Flash options so I know
the swf is loading, but the video from the FLV never loads. Any
ideas?I have the same issue. Everything works great in Flash 7 and
8. I am playing .flv files from a different spot in the server and
I am calling them from a swf file.
In Flash 9 the file won't play. Here is my sample file:
http://ce.byu.edu/cw/yase/.
The quick fix security.allowDomain("*"); has no impact on this
call. I am using my_video.attachVideo(stream_ns); to load the
video.
I have changed the mime type in another server, restarted and
I have the same problem. Any help would be great!

Preview: Alpha Select (background removal) - not working for me
The help says "choose Instant Alpha from the Select pop-up menu"
I see Select in the toolbar with a pulldown arrow, but clicking it does nothing. The only select I have on the previewed image is a scalable box...
I'm stumped, I can't seem to find out how to get the background removal working in the new Preview.Click the button for a short while, a drop-down list should appear. Select the Magic Wand Icon and your Pointer should change to crosshairs. Click and drag to control the colour-difference to be converted to Alpha.
Once you have selected all the sections you want to convert, press Return or Enter; Voila! -
