Uploading Flash Videos to Youtube
February 16, 2009 1:01 PM   Subscribe

I recently started making animated movies in flash. When I upload them to Youtube or Google video, the audio translates well but the video becomes very jerky. I assume its a byproduct of the way they compress the files, but is there a way to avoid this?

For example, in this video, the blanket is supposed to come up in a single smooth motion, and the wink is one smooth motion.

It's especially bad at Youtube, which is a shame, because Youtube is more popular and so I'd rather use it more.

Does it make a difference if I upload a .swf file or a .mov file? Is it because the file size is too big? Would it be better to save it a higher resolution? Am I just uploading them wrong?

I think the animations I've done so far are coming out pretty well, so I would really appreciate anything that would help me show them to people in the way that they were created.

i've found that videos look better on vimeo, but if your files are .swf already you don't actually need to upload them to a video hosting service. if you've got web space somewhere, you can just put the file in a directory and point people straight to the .swf or embed it in a page and share that page.

Part of my job is exporting clips (promos for a TV show) for YouTube. Here's what I'd do:

Export to a mov file first. Export them to either a 4:3 or 16:9 (widescreen) ratio. Ours are typically 640x360 (16:9 because the show's generally widescreen) and they look sharp. If you're going 4:3, I've used 640x480 with success. You might have your flash stage set to a totally different ratio, and you'll need to find a way to letterbox or pillarbox the movies if this is the case to avoid distortion (it occurs to me that you can change the size of the stage and add a layer of black underneath everything to accomplish this).

Here are the settings that I use for movs destined for youtube:

h.264 codec, 1800 kps video bitrate
29.97 frames per second
128k mono AAC audio.

Hope that helps.
