Motion Blurring

[Jim3]

I have just upgraded my psp to 3.40 oe-a.

I decided to encode some video in the newly supported 480*272 resolution.

This is when I came across your software. I used your software to sucessfully convert a xvid avi file to mp4

It plays fine, audio is in sync, nice resolution, nice sharp picture.

However there is a noticeable and fairly odd motion blurring in the encoded video file produced by PSP Video 9 (Ver 2.17). The motion blurring is most noticeable on peoples faces. In particular around nostrils and lips.

I checked the source file and the motion blurring does not occur in the original.

Which means the motion blurring is introduced in the encode by PSP Video 9.

When I encoded the file, I just clicked round the basic options and only altered the settings so that an AVC 480*272 768kbps 2 pass mp4 file was produced.

I'll have another play with it tmrw night see if I can get any better results.

Just wondering if anyone else has noticed or encountered this?

If so, please provide some insight or instruction on how I can go about eliminating this distortion from the encode.

The file I was using as a source was "heroes.119.hdtv-lol.avi"

The file that has been produced by PSP Video 9 is quite large (250 MB) but if required I can upload it or at least part of it to demonstrate the blurring.

Thanks for providing us with this top software by the way

Jim

*** Edit ***
Managed to play the PSP Video 9 encoded file in VLC on my windows xp machine.
The motion blurring is not present in the file when I play it VLC. So it must be a problem with the PSP.

Have you ever encoded PSP video before? I've found there is always a certain amount of blur effect on the PSP, even on some UMD video. Your pc and or video card are much better equipped for handling resolution rates. You can tone it down a bit by increasing your bitrate, but of course that will also increase your file size. Also, the better the original source the less this will happen. If you encode from a vob you will get much less blur than encoding from an avi of the same show/movie.

BTW in case you didn't realize it, this really doesn't seem to be much of a support forum...more like users sharing speculated information.

Thanks for the reply.

Sorry to use the forum for support. Was just after some feedback and maybe some suggestions for settings, and see if anyone else had noticed similar motion blurring effects.

Its the first encode that I have done for psp.

I have done bits of encoding in the past, converting avi files to svcd and mpeg2 using TMPEG.

I'll take your advice and have a play round converting some vob files.

I'll report back with the results when I've done a couple of vobs.

I read somewhere(might have been the other PSP Video 9 forum actually) that lowering the video to 24 fps may decrease motion blur. You could also try increasing the video brightness, may also decrease blur.

What your referring too is "ghosting" and this can be eliminated by using Avi Synth Script.
Add some Sat, Brightness and contrast and you can get rid of this annoying problem.

Hi there!
Has anyone cracked the ghosting/motion blurring problem yet? I'm getting the same problem myself, I've read a few posts about it and was wondering what's the best way of reducing it.

I've been converting from VOB files, is making adjustments in avisynth the way to go?

Thanks!

I to have the blurring with some videos. On some of them, You could really see it in the backround when it is a night setting. If anyone knows how to get rid of blurring in the backround or anywhere else post it here please.

[scrufftyguy]

Any ideas anyone?

I'm mainly getting blurring during dark scenes mostly when there's black against white. I'm converting at 768 kb, AVC 2 pass.

Thanks!

a higher bitrate "might" help that but if your original video is doing it, there's no way around it really.
