Slow motion converter for MVI's

someblokecalleddave · 29 Nov 2008, 16:15

Hello, I've just got myself a Canon G9 camera that shoots very good video clips or varying sizes that download to the computer as MVI files. The camera itself has a really good function in that it allows you to play back the video files in slow motion, which as I'm sure you can appreciate is exceptionally useful for self evaluation of your techniques (Batting bowling). But what I'd really like to be able to do is convert the MVI files into slow motion clips once they're downloaded to the computer so I can then up-load them as slow motion clips onto youtube so people can have a look and give me some feedback. Is it possible to convert MVI files into slow motion clips - if so how?

Don't worry about this now as I've sussed it!

Can you please tell me how to do it dave?

Thanks.

1. Go to this website and download virtualdub - 1.8.6

Welcome to virtualdub.org! - virtualdub.org

Then follow these instructions......

Get VirtualDub. Welcome to virtualdub.org! - virtualdub.org

Open your video file in virtualdub. Click on audio. Click no audio (this is needed, since if the video plays in slow motion, the duration of the audio won’t match). Then click video. Click direct stream copy (so the conversion is lossless). Then click video. Click frame rate. Under 'source rate adjustment' select the 'change to [blank] frames per second' bullet and type in a frame rate (smaller than the one on the line above it, obviously). Then click file, save as avi, and you’re done.

Honestly - I'm crap at computer stuff and I had this sussed in a matter of minutes. If you get any problems contact me via my blog or on here somewhere and I'll try and help - but you should be okay. It is amazing.

This G9 is amazing too, I'm loving the time lapse mode!

this would only work if the initial video is a high enough frame rate its doubtful without specialist high quality equipment you cn get more than 30 fps

You're showing off now. I think Jonesy has got the same camera as me Canon G9. I think when the camera is using it's highest quality setting it's around about that kind of FPS and as I recall the software has as it default starting point 30fps and then you can slow it down to 1 fps which is obviously easily as slow as you'd want to go? But as I said I'm not that technically minded when it comes to these kind of things and I may be talking out of my Jacksy!

I've not looked at the data on the camera - but tried it out. I tried to film my hand close up so that you can see what happens and you're right - it doesn't have the ability to capture that kind of high speed movement. But at work they have got the gear but it captures to DV tape as far as I know and the problem then is converting that to an uploadable format AVI or what have you. But I'm tempted to look into it as I'd love to see some of this stuff in real ultra slow motion.

To get the best results in slow motion try using a 60 fps mode for recording if possible.

Or otherwise, 30 fps is good enough nevertheless.
