group of pictures

hello,

 

after saving my movie in .avi i get following problem: when jumping through the movie it takes a long time till my player (vlc) has loaded. i heard there is often a option within video editors in general called GOP (group of pictures) where you can adjust the number of frames taken into seqential packages. it seems that videopad puts all frames into one package which forces the videoplayer to calculate all frames each time when jumping forward or backward.

 

how can i change this behavior?

 

sometimes i get also on some spots pixelating pictures ...

 

cheers

Hi,

 

GOP settings are currently automatic and hidden from users. I think it would be useful to expose the settings. For example, YouTube is suggesting GOP settings for uploading videos. I'll file your post as a suggestion to our team.

 

sometimes i get also on some spots pixelating pictures ...

 

It's likely caused by codec compression. Increase compression quality or bit rate form encoder settings might solve the problem.

 

 

Best Regards,

Hi,

 

thank You a lot for Your answer! am sorry, i was a bit buisy ...

 

to set the gop-options would be great in the future! however i could get along without if the settings are set automatically to an appropriate value. i mean, i dont know, maybe there are other reasons for this anoying behavior that i can skip through the video. so i ve made screenshots with my settings

 

also i have analized an output video with gspot, here the results.

both you can see here

 

with this video i got waiting times when skipping forwar or backward between 1sec and 10sec, where in general i get better results when playing with divx-player than playing with vlc-player. also the pixelating effect appears mostly with vlc.

 

can You see a reason for this behavior with the given info or do You need more?

 

best regards

leo

In VP, the H.264 encoder will generate at least 25 I-frames/second by default.

 

The screenshot of the analyse software doesn't not show GOP settings (they are empty).

 

Do you mind share the video (via DropBox or Google driver etc.) so we can investigate?

 

I've tried export a few videos and playback with VLC. I didn't get the delay but I saw the pixelated after select "faster" the second time.
