Hi.
I am extremely upset, I was supposed to submit a joined video file with my paper. I forgot to join them, didn't think it would take that long. I've spent all day on this. I've broken things already. So I really need help. With anger management but also video help, which is specifically why I'm here.
I have two short clips, both only a few seconds. One is 295 x 614, the other is 856 x 788. I have them originally in .mov format. I have converted them to AVI also.
I do not have quicktime pro, could not find in an exhaustive search of my lab building any computers that have it, and am not inclined to buy it. Both on principle and because I expect I'd buy it only to find it didn't work for my files and would be obligated to stomp my computer to bits.
Avidemux was the program that finally broke me. It refuses to join two files of different sizes, and there seems to be no way to resize them without converting to a different format and making the first movie stretched out to the point of uselessness. And a lot of crashing.
EZ joiner / easy video joiner crashes without any explanation every single time while trying to join the AVI files, and doesn't recognize the mov files.
iskysoft video converter leaves a watermark in the converted videos, and is right out even if it does join files.
I have windows 7, 64 bit.
Edit: The framerate is also likely different.

You cannot join videos of different dimensions or fps . You need to change one to match the other. All characteristics have to match, including codec, audio sampling rate, channels, fps. Think of it like using a phillips screwdriver for flat slot head - it won't fit
Start with describing why the videos are so "odd" in dimensions. Were are they from, what format, and what's been done to them to give 295x614 or 856 x 788 ?????? Surely they didn't start like that
So you can either pad (add borders) +/- resize one to match the other -
They are movie files generated by Imaris, they're from microscopy files.
They were cropped in this way to focus on specific cells moving around. The framerates are odd because both are time lapse movies. They were sped up or slowed down to focus on different movements.
What program should I use to adjust the size (add borders) or adjust the frame rate?
There is no audio data. -
Then your best bet might be to create a playlist so that they play one after the other.
-
Did the program export it in that format? Are the framerates variable ?
Use mediainfo (view=>text) copy & paste the text report back here for each original video
Do you understand your options? You would probably want to add black borders to the smaller one to match the larger one. You might have to do other things, like normalize the FPS if you intend to append them
What is the final format goal ? Where and how is this going to be viewed? e.g. on a website, DVD, blu-ray , PC, etc.... That affects the format you choose -
Ah, forgot to mention why I was joining these. I'm submitting a paper, there is a limit of three supplementary data videos allowed, and there are two other videos that I needed to include. So leaving them seperate is not an option.
And now that I look at the requirements, the video needs to be resized anyway:
"JCB accepts .mov, .mpg, and .avi files. Please verify that all videos are viewable in QuickTime before submission. Note that in some instances it may be necessary to re-save from within QuickTime Pro.
Videos may be no larger than 10 MB. JCB recommends H.264 compression, although other codecs may be used. However, please do not use MPEG-1 encoding or Intel Indeo because of incompatibilities across platforms. Color depth should be kept to a minimum, using grayscale for black and white videos. Frame size should be limited to 520 x 420 pixels."
I do get that they need to be the same framerate and size, that makes sense. When I try to "add black border" in avidemux though to make the smaller one the same size, the image colors look split in the preview. I'll try fully processing them, I realize I hadn't done that yet.

The other problem is video #1 has a 20 FPS frame rate, video #2 has 6 FPS frame rate
I'm assuming the speed of the video is imporant ? (the actual motion content of the video, where the cells are doing their "thing") ie. you don't want to speed them up or slow them down from what they are now ?
The lowest common multiple is 60. So you would have to duplicate frames to achieve that (e.g. 20 FPS would be equivalent to a 60FPS video with every frame duplicated so there are 3 of every frame)
And now that I look at the requirements, the video needs to be resized anyway:
Frame size should be limited to 520 x 420 pixels
When resizing, you probably want to keep the same aspect ratio , otherwise things get distorted (e.g. a "round" cell might become "oval") -
Problem solved using avidemux.
I lowered the framerate of the 20 fps one to 6 (the data was not at 20 fps anyway), resized the images and added black borders to make it fit, then joined them and saved as an mpg file.
The resulting file is not as pretty as the original data, but most of the readers aren't going to bother with it anyway.
I appreciate the pointers.
If you're curious as to the resulting file, I uploaded it to youtube here

Thanks again! -
Well I just tried joining 2 different dimension videos , and fps, and audio tracks, in quicktime pro - it actually works!
What happens is the smaller frame video takes the size of the larger frame video, but is placed in the upper left hand corner. The "borders" are white. There are even visual options to reposition it in quicktime - so you can center it . BUT... it ONLY plays properly in quicktime. There must be some metadata that other players cannot access
If you upload the videos somewhere to a free hosting site (e.g. mediafire.com, sendspace.com) , I can offer to do it for you
EDIT: I didn't see your last post, glad it worked out for you. But I learned something new here about quicktimeLast edited by poisondeathray; 7th Mar 2012 at 17:43.
