frame freeze at start of fullscreen...

[exo-tech]

hi, im a newbie encoder, and everything so far has been good. i've been ripping anime, and the results with xvid are pretty satisfying. however, there is a peculiar oddity that frustrates me. i'm not sure if it's something i missed or did wrong, or it is a property that is not fixable at this time.

when i view the video, if i fullscreen it, the frame will freeze for a few seconds before it continues again. normally this happens some seconds into the video, and rarely when i jump to a certain frame. is it a windows media player thing, or an xvid thing? is it fixable? ^_^

and another thing is...if i jump to a certain area in the video, the audio continues, but the video stream has to catch up to 1x speed...i only notice this on xvid encodes, not divx encodes. just wanted to know if there's something i was missing...=)

tks in advance for your replies [i hope i get some ^_^]

________edit________

i forgot to include...i'm using koepi's latest unstable build [although i've encoded w/ earlier builds, and the same situation occurs] -- i have a p3 800 w/ geforce 3...as for the other things nic requested, im still too much of a newbie to know what to post ;X

hrmmm...noone knows of what im talking about? =(

What decoder are you using for playback? What you are discribing sounds like the DirectShow filter you are using has a problem.

You can install ffdshow and see if that helps, or you might concider changing your FourCC to DX50 so it will be played with the divx filter

sorry to sound stupid, but where do i go to check which decoder is being used for playback? i checked everywhere on wmp (or so i would think =[), but i couldn't find anything of the sort. i had thought i had ffdshow, but i didn't...so i went and downloaded it, but alas, it didn't fix the problem. i tried to open it in power dvd and see if that had any difference, and it didn't...=( anymore help would be greatly appreciated ^_^

If you open up the the video in WMP 6.4 you can goto File / Properties click on the Details tab, there is a list of filters that are used to play the video. If you are running WinXP or have updated to WMP 7.1 you still have version 6.4 in "C:\Program Files\Windows Media Player\wmplayer2.exe" The reason why I want to you open it in WMP 6.4 is because the properties can't be seen in the later versions of WMP.

You could also download graphedit from the download section and render the media file there. You might be able tweak the settings there to help your problem.

Was your video encoded with the unstable options? (aka b-frames, GMC, Chroma Motion, or QPel) These could cause a problem.

-default directsound device
-directvobsub [auto-loading version]
-ffdshow mpeg-4 video decoder
-morgan stream switcher
-mpeg layer-3 decoder
-video renderer

...those are all the filters being used. codecs in use is blanked. and no unstable options were used to encode the rip, except the bframes options is at -1, 150, and 100 from top to bottom...

I dont know if it will help but get rid of morgan

[TelemachusMH]

If you don't have multiple audio track in the movie, and you don't have subtitles in it, You might concider using graphedit to take out morgan stream switcher and DirectVobSub. I also would like to know if your source is an avi or an ogm? Make the graph like this:

File Source (Async) --> Avi Splitter --> ffdshow --> Video Renderer
___________________(Ogm Splitter) \
________________________________--> MPEG Layer 3 Decoder --> Default Direct Sound Device

To find these filters you can open graph edit and goto Graph/Insert Filters. The all of them will be listed under DirectShow Filters except the Default Direct Sound Device which is under Audio Renderers. Once you have the graph try playing it by pushing the green > on the toolbar.
See if this helps play it correctly, if it does I'll tell you how to make that the default so you can just open in in WMP and play.

PS The underscores in the graph are just placeholders to make the lines line-up correctly.

This problem just seems like the video not catching up until you reach a keyframe. Jumping to a non-keyframe requires extra computing power since the player must go to the previous keyframe and interpret all delta frames from there to the frame you're on. This happens occasionally in not only XviD files that I have, but also DivX. If it means that much to you, you could decrease the maximum keyframe interval.

telemachus: it plays fine in graphedit, but that's because i can't full screen it...the trouble comes when i full screen in the beginning, it causes the frame to freeze for a few seconds, then returns to normal. or, if i play it and fullscreen it immediately, and then de-full screen it in the beginning of the intro, it also freezes [now windowed]...how do i render the new avi w/ graph edit?

[TelemachusMH]

Y7 is probably right, I didn't realize that this happened only when you switch from full-screen and back. Chances are that you can reencode the video with a lower keyframe distance, or you could just leave it as is.

well i had thought that to be one of the reasons...but why only during the intro...? on all the encodes that i have done also. and it unfreezes at the exact moment, everytime...could it really be the keyframes? where do i go to adjust this option?
