TheFluff and others have gone over this way too many times. This is in no way personal, but every time someone mentions VirtualDubMod something inside me dies. Not to mention the age of the aforementioned spinoff, it also really doesn't have any real features compared to the current, up-to-date VirtualDub.

hm im the only one with the problem that i cannot open mkv in virtualdub or virtualdubmod (with avisynth the same). [OS is w7 64bit] ^^ With Vista 64bit everything is fine. Only option is to convert mkv to avi etc. right?
everything is fine now 2 codecs were currupted. sry for this stupid post ... *bow*

Requirements: VirtualDub (optional) GIMP, or any other image editor. APNG Anime Maker Ready to animate PNG frame sequences. Limitations: Animated PNG files only work in a few image viewers and web browsers. See: http://en.wikipedia.org/wiki/APNG#Application_support for more info. Image viewers and web browsers that do not support animated png will generally render the image as a static image. This would be the first frame only. Some image file host providers, such as ImageShack, do not support animated png. Process - The short version: 1) In the earlier GIMP guides, this is where you do not want to convert your ordered frames to Indexed mode. Instead, you will need to save each individual layer as a PNG image. (Lowest layer being image #1, second lowest layer being #2, and so forth...) One method of doing this without having to delete frames, is to toggle visibility on the Layers window so that only one eye is visible. Spoiler for Eye Example:
Then when you do File/Save As, save the first frame as 001.png. Once you click on Save, you will see a pop-up stating that the PNG plug-in can't handle layers. Select from the below option, Merge Visible Layers, and then select Export. Within the next pop-up window, the only thing to make sure not to enable is the interlaced option. Save, then toggle visibility for the next upper layer, and untick the eye below that. Then repeat the saving process, but with saving with a different file name; a name that will indicate the frame sequence. Spoiler for Eye Example:
2) Using the APNG Anime Maker program, Select Open, then navigate the pop-up window to the folder that contains your edited PNG images that you had created at step one, select the images, and then open. Spoiler for APNG Anime Maker:
Make sure that the frames are ordered, the top being the first frame sequence. If a frame is listed out of sequence, select with a left-click of the mouse the out of ordered frame from the list, and select from the above options, Move Up or Move Down, depending on the direction of where you need to relocate the frame. Once in the order that you desire, select Save to save as a animated PNG. (File extension will be .png ...the same as a static png image.) Spoiler for APNG Anime Maker:

I need some help.
I've never used Photoshop in my life before ( except today ), or created an animated GIF for that matter.. I only have the most basic knowledge that I got from reading the tutorials around AnimeSuki. Setting aside the times in frames and such, could anyone see if they can reduce This GIF into 50kb or less, and then tell me how they did it ? I do realise there are 39 frames which is ALOT, but since all frames are different, I have no idea what frames I could remove - if any. I used the auto-optimization tool in Photoshop but the quality came out really awful .. There was also some guide for reducing file size where you deleted some of the backround or something.. but I dont know if it would work here, and if it would .. how ? The guide presumed I had previous knowledge of Photoshop so I had no idea what to do. Oh and, any tips as how to use the tween effectively ? It just doesn't seem right to me what I did there with that gif. --- Is there an alternative program for VirtualDub ? For now I'm using ffdshow but it's quite troublesome to use .. VirtualDub would have been nice if it had actually worked. The normal version doesn't even support .mkv files, and when I got some mod for it that let me load .mkv .. Well, when I chose time frame, it didn't tell me how many frames were in that time frame, neither it did let me save those frames as pictures onto my computer ..

Fixing that without doing something drastic, like making it grayscale, to be less than 50 kb is near impossible. Not to mention when I try to edit it, I get a trash file. |

Here's what I'd suggest. Start with the original sequence and go through each frame one at a time in a graphics viewer. Watch how the frames change. Typically you'll see that each frame is repeated two or three times. Keep only the ones that are different. Then try creating an animated avatar from the resulting frames and see how small it is. If it's still bigger than the 50K limit, you'll need to start dropping intermediate frames. You'll be surprised at how few frames it takes to create a reasonably smooth animation. My current avatar has only nine frames. That's because nearly every frame is identical except for the arm and mouth movements. Creating a good animated avatar within the AS limits takes a lot of experimentation. I often spend an hour or two before I find the right set of frames that preserves the look of the original yet fits within the limits. You might find you'll need to make something smaller than 100x100 to comply. You'll also need to work out the timings. Remember that there are roughly 24 frames each second, so if a frame is repeated three times in the original sequence, it needs to be displayed for about an eighth of a second, or about 125 milliseconds, to preserve the timings. I work entirely in Linux and use mplayer from the command line to extract frames. Both I and Green2 have written up methods for doing this that appear in the thread above. I'm not suggesting you switch operating systems, but whatever you use shouldn't require that you convert to AVI. You just need software that will extract the frames as individual GIF or PNG images. If VirtualDub can do that, you should be able to reassemble the frames as layers in Photoshop or GIMP. Edit: For a truly awesome example of what can be done within the AS size limits, take a look at this avatar by Pellisier.

Thanks for reply.
My friend actually tried to open the same GIF in his GIMP and said something about empty frames aswell.. I don't really know what's going on with that, since it doesn't appear like that in Photoshop .. I used Save for Web and it got to the size that it is atm. I read a guide by Evil Rick ( I think ) that said something about removing static backround from each image to reduce file size, but the guide presumed previous knowledge of Photoshop and I have none so I don't know how to do that .. Unless it has been done already by PS ( seeing as you got empty frames ). Also I did that and removed all duplicate frames, but I didn't know about the timing thing.. Could you be more precise what you mean by reworking the timing ? Lets say there's two identical frames.. I delete one and what should I add as the time for the other ? What if there are 3, 4 or even 5 identical frames ? I also need some feedback/tips with the Tween effect, I only added it to the end as an experiment but I don't really know how it works or how it should be used. And lastly, like I said VD doesn't open MKV files for me so I can't use it. I would be fine with any other program there is, that can do the job but I don't know any .. Well, I suppose I could use Movie Maker to get the clip but then I'm still left with what software to use ( free if ossible .. )

When you say "it doesn't appear like that in Photoshop," are you talking about the original before you "saved for web?" Or did you open the gif itself separately in Photoshop after saving? If the latter, I'd be surprised that you can't see the empty layers. Now you do have to make sure that you're looking at each layer by itself, not superimposed on the background. In GIMP there's a simple method to do this; opening the Layers window shows each layer as a separate image. I'm sure there must be a way to accomplish the same thing in PS, I just don't know how you'd do so. For example, here's the "background" frame of my avatar followed by one of the differenced frames: Quote:
Timing is simply a matter of arithmetic. Most anime is shot at (approximately) 24 frames per second, so each one appears on screen for 1/24 second. To save money, animators often repeat a frame multiple times; most televised anime is shot "on threes," meaning each frame is repeated a multiple of three times. So it's pretty common to see three, six, nine, etc., identical frames in sequence depending on how long the director wants the image to remain on screen. Animated gifs use a different method to control how long a frame appears. When you save to gif, you can designate how long each frame should be displayed, typically in milliseconds (1/1000's of a second). So if you find three identical frames in sequence, you can reproduce the director's timings by using just one of those frames, but displaying it for 3*(1/24) seconds, or about 125 milliseconds. Often I'll have the initial background frame, and sometimes the final frame, display longer than the intermediate ones, as in this case: Here the background appears for 2.5 seconds while the motion frames appear for just 0.12 seconds each.

^Go back to my first post. GIF with 39 frames already saved for web and size is 86kb. Trying to reduce the size any lower makes it look awful. I'm trying to ask how to reduce the file size some more, and how to benefit from the guide Evil Rick posted to remove the static backround from each image ( so only parts that move are saved except for first layer ) to reduce file size even more ..
Although now I am not too sure if that's done by PS automatically or not. I'm using CS5, and my knowledge of PS is zero.

Well the original image sequence was like 150kb and then I optimized it to 80 which was still acceptable, but getting it to 50 seemed near impossible.
What I was trying to find out here was how to do this to the original image sequence that I hadn't optimized yet. ( My bad I told it was by Evil Rick, somehow confused the names ) But then, when I had optimized the GIF and my friend opened it in GIMP he said there were alot essentially empty layers so I don't really understand if Photoshop CS5 does what that guide explains automatically when optimizing, or should I do what's told in the guide ? Additionally, the guide presumes previous knowledge of PS but I have none so I dont know how to begin with that guide.

Summary: The answer to your question is 42.Photoshop is basically a set of tools. For simple stuff using just the tools is sufficient, and in your case using just a few of them in combination is sufficient. The following are the so called "basics," feel free to skim though them at your leisure. If from the first few words of the paragraph you feel you are familiar with the concepts, I recommend skipping forward to the next.
When you import images as frames, or open a gif file, you'll get a layer for each "frame image" you extracted from the video, or in the gif. Layers can obviously exist with out frames but for the moment there's a one-to-one relationship. I'll use your gif as a example, but do try to start from proper frames when you make them. If you zoom in to 400% you'll see something like this: Figure 2: Problem #1, duplicate frames. If you have 4 frames (or whatever number) like that then just remove 3 of them and make the one remaining frame have 4 times the normal timing. In this particular instance there's not much movement in pixels, so even that big ass avatar example in fig.2 is only 42.11 KB, but it could be a lot worse. Don't bother with shallow details, things like eyes flickering are barely noticeable. Other details like mouth opening are arguably equally redundant for a gif but that's personal preference. Figure 3: Problem #2, more pixels moving in the static part of the animation. When you save it at 100px by 100px, people are not going to notice the small fluctuation in pixels, but the size will get effected. More movement, bigger the file size. When you lower colors some of these issues tend to go away since a lot of the pixel movement is basically color fluctuation from the video. But you don't want to sacrifice color for reasons like this. There are quite the number of ways to get rid of this. The closer to the top the easier to pull of, the closer to the bottom the more extreme:
The transition is a Tween. Create a frame with the end layer at 100% transparency, then another with 0% and 100% on the first frame. Then create a Tween between them, all done. When saving, you want to do the following, by priority:
Also, always preview the timing in the browser! not photoshop. You can use photoshop to get an idea but don't bother with anything more then that. You'll find the button for preview in browser at the bottom of the Save for web... dialog.

Hey guys, I have a quick question. When I export an image sequence in virtualdub, I try to open it in imageready(to add border) and when I view the optimize tab, it's all black/white/gray.
Same problem comes up when I export a .gif from vdub and try to add border. Just wondering, is there any other way I can add a border without using Photoshop/Imageready? |
