How to convert jpg pics to avi?

[pmolson]

I've used 1st converter to convert a 5 min avi file (video+ audio) to 1000s of jpg pics (frames). that same software allows to take in pics (i.e. jpg's) and covert them back to avi. I did that and chose xvid as a video codec and frame rate of 29.97fps, but when I view the avi it does not stream like the original avi did. I mean the frame are moving but very slowly!!! How can get picstures and create a TRUE avi fille that streams the pics fast enough as if you were watching a movie? THX

The framerate has nothing to do with it, there is usually a default length of time each image is viewable. Check the options in your program.

Hey thanks for your swift response coalman! ...I have found it...the default was 4s, and even when I've changed to 1s, it still too long/slow...What do you recommend I set that variable to?...I even tried 0s...same result THX

[pmolson]

btw, when I play the original avi the clip ends in 6s, but when I play the avi file I just encoded (using 186 frames: jpg's), it takes 3m7s to go over the whole thing...There is definitely something wrong here...pls help THX

Each jpeg is one frame, you need to display it for 1/29.97 of a second, 0.0333667 seconds.

[pmolson]

Thx guns! I've used 3 tools already and they all ask for an integer. None of them allows you to enter a fraction (decimal)!!!

[Cornucopia]

Then you're using the wrong tools. What have you tried?

"photo slide show" (converts jpg frames to avi)
"1st video converter" does same thing
"Window Movie Maker"...same thing

THX

[Cornucopia]

jpg2avi. Just tried it. Works great (although you have to pay 25euro).

There are other good ones. You should be able to get AVISynth to do it. Check the guides...

Scott, I've already dnlded it and it too DOES NOT let you enter a fraction in the transition field...in fact as soon as I've loaded the pics that field became grayed out!! and when I process the avi the output is the same...TOO SLOW!!!

[guns1inger]

slideshow programs are making slideshows, not movies. You need to use an editor to do this. Even virtualdub will import and image sequence and allow you to save a video.

I didn't think vdub takes in jpg frames and converts them into movies!!! Menu only shows "open video", and when I try to load in anything else I get an error. how to do you get it to accept pictures? or can you recommend any other tool? THX

[thecoalman]

If they are all doing the same thing it sounds to me as if you have a playback problem. As I mentioned the framerate is irrelevant as far as the length of time the image is displayed. For example if you set the frame rate to 15FPS and the amount of time the image is displayed to 1 second the application will create 15 frames, if you set it to 2 seconds then it creates 30 identical frames... and so on.

Your player reads the header information and plays back the video at whatever the FPS is.

[pmolson]

Coalman, I understand what you're saying and it makes total sense, but what do you mean by a "playback" problem? All I do is play the avi (created) in WMP or KMP...why would that be a problem?! I think, as you've mentioned earlier, I need to be able to encode it correctly in the 1st place, before I can play it as movie. with that said, what tool do you recommend will allow me to do just that i.e. transition the frames every 1/30 of a second? THX

But id does.

Menu only shows "open video", and when I try to load in anything else I get an error. how to do you get it to accept pictures?

Select "Image sequence" in the File type dropdown in the Open video file dialog.
At least it works in VirtualDubMod.

[JPG2AVI]You're getting ahead of yourself...
Start the app. Load the pix. DON'T mess with framerate on the main page! (It's already set to 0). Set your framerate in the AVI output properties dialog. I did a test of ~200 pix, set output type to DV, 720x480 @30fps. BOOM! Done.

........
Duh! (butts head with hand)
thecoalman and mats are right. USE Vdub (any of the variants should work).
In the Open Video dialog, the dropdown for type should be changed from Movie (AVI, MPG..) to Image Sequence.
Easier done than said.

[pmolson]

Thanks for your input guys...Mats, I've followed the steps in Vdub (as described in your post above), but when it opens the folder that has 1000s of frames (i.e jpg's) it only allows me to select/load 1 pic at a time! (shift select or select all) does not seem to work! What am I missing here? THX

[thecoalman]

Coalman, I understand what you're saying and it makes total sense, but what do you mean by a "playback" problem?

You list your computer specs as a AMD 1800, that's not a lot but I'd imagine it could play most files but I really don't know. what I'm suggesting is maybe you're computer is choking on the files and the slow framerates are due to your unpowered CPU or some other issue. I'm only saying this becaue you are having the same problem with all the applications. Probably the easiest way to check is add a audio track.

[pmolson]

I have a 2.8 GHz P4 CPU and 1G of RAM...I don't think the PC is the e problem. I can play other AVIs' just fine...I need to update my profile I guess...THX Anyway Bud! Now I'm this close...if someone can just tell me how to load multiple (I mean 100s of jpg's using Vdub...I'd be 1/2-way there...THX AGAIN

[45tripp]

they have to be sequentially named and have the same dimensions.

image0001
image0002
image0003
etc

load the first image

[mats.hogberg]

I think they have to be numbered somehow. Googling for "virtualdub load image sequence" turned up this at the top: http://www.virtualdub.org/blog/pivot/entry.php?id=34

I've tried it with a few sample pics and it's working! Thank you guys!

I came across this thread. I tried making an .avi video with vdub, and it works. How would i make an animated gif out of the created .avi file, where the movement is normal speed? I made one and it's speedy gonzalez! Help.

Edit: Nevermind. I simply must change the frame rate of the video to like 2 in virtualdub. Then i export it to animated gif. It's beautiful now.

Hi, I found this thread in my search of on ONLINE tool that will convert JPG to AVI files.

Here's the deal: I'm a teacher working in a school district that doesn't allow us (and wisely so) to download our own programs. I want my students to be able to use our cameras and the school computers to create a stop motion video.

In the past, we have used GifMaker.me to create 20 frame gifs that we then put together in Movie Maker 2.6 to make our movies. Tiresome, but a good way to help them learn to download photos, organize folders, upload photos, download and find files, edit, etc.

Our problem: Movie Maker 2.6 is a dinosaur and I would like to use Windows Movie Maker Live which is more current (and the only other video editing software allowed without a 15 person district wide committee convening on it's educational relevance)

So what I'm trying to find is something like GIFMakerMe that's online and turns batches of JPGs into andAVI file. Any ideas from you pros?

[Cornucopia]

@JustTeaching - first, I would suggest that it would have been better had you followed the protocol and started your own thread. Regardless, the problem with online services doing what you're looking for would become unwieldy once you start getting into longer and longer sections. Plus, there is little control over specifics of your destination format, AND you have to watch out for online services' "terms of service" (both monetarily, copyright-wise, and security-wise).

There are a number of apps that can do what you want that are PORTABLE. That means, you don't INSTALL anything, you just use the app (with its self-contained dependencies). Assuming your situation is NOT so locked down as to disallow usage of removable media (such as USB sticks), you could always download at home and "run" the app from the USB.

If your situation IS that security-conscious (whether by policy or by technology), I'm guessing that usage of online up/down-load conversion services would ALSO be a risky proposition. In that case, it would make more sense to let the "powers that be" be aware of your need and provide a committee-acceptable solution (whether local or cloud-based).
