- \item If you suddenly get hangs on media or strange looking tracks, you might want to rebuild indexes. You can do this in the Resources window with a right mouse click on the media to get a pulldown\ with the \textit{Rebuild index} option. For an easy way to rebuild for all of your media use Settings$\rightarrow$Preferences, Interface tab, Index Files section, ``Delete existing indexes''. This will take some time to recreate all of the currently loaded media and subsequent loads, but can be an easy fix.
- \item On an older computer, if you are playing media and it can not keep up, you can turn off ``Play every frame'' in the Video Out tab of Settings$\rightarrow$Preferences, Playback tab. You will then see the video jump as it skips frames in order to stay caught up.
- \item The \textit{Cache size} can be lowered to 1048 if playback seems choppy or if you have problems with lv2 plugins, or you can increase the \textit{Cache size} for better flow. This can be changed in Settings$\rightarrow$Preferences, Performance tab.
- \item After saving your current session and exiting Cinelerra, you might want to rename your current \$HOME/.bcast5 directory and start with the default setup. This will eliminate your settings as the potential cause of a problem; however, all of your current preferences will be lost until you go back to your original .bcast5.
- \item Some media has only a single keyframe at the beginning of the file so that moving anywhere on the timeline results in just a black image in the compositor. Cinelerra needs more keyframes to determine position. You can temporarily use Settings$\rightarrow$Proxy to 1/2 size to put in keyframes. How to use Proxy is explained in Performance Tips and Other Tips, chapter 19.
- \item If the rate at which frames are captured during Recording is much lower than the framerate of the source, the video will accumulate in the recording buffers over time and the audio and video will become out of sync. Decrease the number of frames to buffer in the device in Settings$\rightarrow $Preferences, Recording tab so that the excess frames are dropped instead of buffered.
- \item If loading files locks up, this might be because Cinelerra is building picons/vicons for the Resources window. If you load a large number of images it needs to decompress every single image to build a picon/vicon. Go into Settings$\rightarrow$Preferences, Appearance tab and disable \textit{Use}\textit{thumbnails in resource window} to skip this process. Keep in mind though, that it only has to create these thumbnails the first time a new piece of media is loaded or the values are changed.
- \item For an older computer with less CPU power, in Settings$\rightarrow$Preferences, Appearance tab, be sure that \textit{Autocolor assets }is disabled; set \textit{View thumbnail size} \& \textit{Vicon quality}\& \textit{Vicon color mode} to lower values or switch to \textit{No Play} instead of \textit{Full Play} in the Resources window (this is to the right of the word \textit{Visibility} in the left hand side of that window). You will then have more CPU and more memory available to do actual editing.
