I successfully build proxy with near default setting the first time but I then realised that the proxys need to be smaller files because the web client interface becomes unusable when you have to wait for the videos to download before they play at all.
After that I tried changing encoding settings for proxy but I can't build proxy anymore and every try ends with an error code -206. Even the setting changes end in an error: "CustomPreview - quicktime.std.StdQTException[QTJava:7.6.0g],-206=badFormat,QT.vers:7708000). In the proxy settings, I can see the drop down menu for different options but pressing the customise button does not do anything anymore.
BTW, can you suggest good proxy settings for web interface where video quality does not really matter as the original files are already of sub par quality?
This seems like good forum to ask technical questions and all the help is really appreciated!
I would like to add that it seems that the only encoding options that work for me are the two MPEG4 options (IIRC quality, normal). Also, the longer QTJava error I reported comes from clicking the customise button with any other option than the two MPEG4 options.
