Best video format for reduced motion blur

[F-16dotnet]

Hi

Long time visitor, first time posting.

Tittle captures it all. What is the best video format for reduced motion blur?

I've been videoing trains and when I converted the images to avi the motion of the train is greatly blured. What file formats are the best? mkv, mp4 etc...

Many thanks,
Jon

You're sure you're not creating the blurring yourself, perhaps by deinterlacing? Perhaps by using too low of a bitrate? Perhaps by lowering the resolution too much?

Do you have some sample videos, before and after? What program(s) are you using for the conversion, and at what settings? What I'm getting at is that I've never heard of specific video codecs blurring more than others.

Ultimately the files are Sony Handycam MTS shot at 1920x1080. For quick viewing the clips, I used Mts to Xvid decoder. It does reduce the resolution, but the blur is pretty obvious compared to the original MTS file. So now wondering if I convert at a higher resultion it won't be a problem then? The MTS to Xvid decoder is a simple program and I do not think it offers controlled resolution settings.

I'll have to try my video editing software (not the MTS to Xvid decoder) that can handle MTS files and see about making a high resolution avi.

I didn't realize reducing resolution caused blur, just thought it would reduce quality of the image. Also, when I used AutoGK to convert my DVDs of Star Trek the Next Generation. It should have retained the resolution but I notice blur there as well.

No samples yet.

Thanks for your help.

Apples and oranges, that one. It's a notoriously difficult series to convert to AVI because it's a true hybrid with the CG stuff created at a different framerate than the bulk of the episodes. AutoGK blends (blurs) the CG to bring it down to the framerate of the film parts. Also, as you mentioned, lowering the resolution from Hi-Def to Standard-Def inevitably leads to much less clear and detailed video.

Is your camera video interlaced? If so, and if you're deinterlacing it (as you probably are if converting it to XviD or similar AVI), the deinterlacer used by this MTS to Xvid program you're using could be responsible. Again, some before and after , 10 seconds of each, might prove useful.
