30 FPS What is the optimal setting? Is it a tradeoff bet. filesize & smooth

[etbrown4]

I am a video newbie.

With much help from this forum I copied and edited 5 videos using Fraps, and put them together. I think the default settings were at 30 frames per second.

The finished piece is a little jerky, but it works.

Can this be changed after we do the Fraps copy or must it be done at the very beginning?

Most experts here wanted me to use Virtualdub for editing, but I found that a little daunting.

I found that Microsoft's free Movie Maker worked just great for me. I thought that part was easy. Drop and drag was a breeze as was shortening clips and titling.

If 30 is not the best setting, what should be? As far as I can tell the file size was not especially big so that would not be a limitation on my next one.

Any constructive suggestions are most appreciated. This is the most helpful forum I've ever used!!!

If you want faster frame rates you need to start by capturing faster. 60 fps is a good setting because most LCD monitors run at 60 Hz. But if you're going to upload to Youtube or some other video streaming service they all work at 30 fps (or less) so you might as well stay with 30 fps.

See the video in this post for a comparision of 24 fps, 30 fps, and 60 fps (you need to be running your monitor at 60 Hz for the best results):

I just looked at your Youtube video and the video is much jerkier than 30 fps normally is. I think you have some other problem.

I just downloaded the 480p video and there a many duplicate frames. Typically something between 2 and 8 repeats of each image in irregular intervals. So there is something wrong with your initial screen capture or your processing.

All I did was download from http://www.obx360.com/brindley_beach/wl1036/360vt.html, and piece 5 videos together.

I used Fraps.

Might it be that the original is just as jerky?

Thanks for any input as I have a lot to learn but it has been fun so far.

Using any of you all's trained eye, can you tell if it is the source, or you'd be welcome to try a quick fraps on the source with a higher fps setting. I'd have a hard time telling, with my untrained eye.

Any observations are much appreciated.

The obx360 animation isn't a video. It's an interactive 3d projection so it's fairly CPU intensive. It's a little jerky when viewed on my computer, but not as jerky as the video you made from it. I suspect fraps and the projector are fighting over CPU cycles. Step through your original capture files frame by frame and see if there are lots of duplicate frames. Compare the smoothness of the fraps files to the smoothness of the video you uploaded to Youtube.

I think jagabo is correct; your fraps capture was probably choppy to begin with, probably your hardware isn't up to snuff

Each scene is actually a single panoramic jpeg , not a video . When rendered through the custom flash player, it is choppy and very CPU intensive. Screen recording it will cause it to become even worse as you drop frames and get dupe frames . Even fast hardware can have problems, because flash is so poorly optimized

You can use a workaround by viewing the panoramic jpeg locally in a viewer , then adjust the rotate speed much slower, and record much lower FPS. This way you don't drop frames or get dupe frames (or at least a lot fewer) . Then you edit it, and set the frame rate back to a higher speed so it plays in "normal time"

See the example attached below



1) Get the panoramic jpeg. They are automatically saved in the temporary internet directory when you view the webpage.

2) Use a free panoramic viewer. I used FSPViewer
http://www.fsoft.it/panorama/FSPViewer.htm

You need adjust the parameters like yaw, pitch, field of view to get the appearance you want , since the settings will depend on how the panorama was made, what angles etc... It might be too narrow or too wide for example

You can adjust the autospin rate to go faster or slower. If you have slower hardware, use a fractional autospin rate, and record at very low framerates . e.g. camstudio (free) , camtasia, fraps . I used camstudio

4) Edit and adjust framerate back to "normal"

This may not be available to you, but the way that the "Pros" do it would be to use 1 computer to do the gameplay/rendering/viewing and another, different computer to do the capturing. Output via HDMI, and cap with a Blackmagic Intensity for the best Digital-to-digital quality.

This cuts the load on each computer, thereby increasing the FPS/smoothness.

Of course, you want both/either machines to be LEAN & MEAN (aka, no other/unnecessary apps/processes/services, using Defragged HDs - hopefully not the boot drive, plenty of RAM & contiguous HD space, etc).
