Video quality

[df305]

I customized the template, made a few little changes, ready to upload video clips now. Before I do so:

Does anyone know of a way to improve the quality of the video previews generate by FFMPEG? Is there a quality setting somewhere in the scripts?

I understand higher quality will increase file size and load time significantly, but buyers might be turned off by the current previews.
Thanks for any help.

Do you dislike the quality of *.flv previews? or the quality of *.jpg thumbs which you see as stretched first frame in the video player?

You can change the quality of flv generation here:

file /admin/function/functions.php

function generate_flv

Code: Select all

$com=$dp->row["fpath"]." -i \"".$apath."\" -b 300k -ar 22050 -t ".$duration." -f flv -s ".$wd."x".$ht." ".$flv_path;

Thanks for the reply.
Just tested with the new settings - works perfect now!

You should read about On2 compression in flv. Not every server support this technology. It gives good flv quality with small file size.

sorry - codec name is VP6, On2 is producer.
Big guys uses this codec in their stocks

Thanks for the info, Lucy. I will look into it!

Since you are the one that created the great trick that got rid of the black bars - do you have any idea why the script that copies files to AMAZON brings back the black bars ???

Thanks for any help on this!

I don't have the newest version of the script installed but I guess the flv player has wrong dimmension. And now some different line is responsible for taking flv from S3 and launching flv player. You have to find this line.

Sorry Anton, just wondering where is the bit I have to edit for the quality? I assume its the 300k or 22050? What do they refer to?
Thanks

300k is video bitrate.
22050 is audio sample rate.
