EZTitles provides you with complete control over the video material. You can play it in both directions at different speeds (normal, 2x, 4x, etc., up to 200x) or stop still at a specific frame.
The sound is synchronized with the video and is played at the same speed as the video is.
It is also possible to browse through the video file frame by frame. In that case the sound corresponding to the current frame is played at half the normal speed.
The Audio time-stretch filter significantly improves the sound quality when playing at speeds 1.5x and 2x, removing the pitch and keeping the speech understandable.
The filter can be switched on/off from the Edit/Preferences/Performance menu.
Note: To be able to use all keyboard shortcuts make sure that the Num Lock on your keyboard is off.
Alt+Right or the Play toolbar button – plays the current video file forward at normal speed;
Alt+Ctrl+Right – plays the current video file forward at 1.5x speed;
Alt+Up, Alt+Down or the Pause toolbar or keyboard button – stops the video playback at a single frame;
Alt+Left or the Reverse toolbar button – plays the video file backwards at normal speed;
Pause keyboard button - stop or resume playing.
Increasing and Decreasing Speed
Alt+Shift+Down – reduces the playback speed;
Alt+Shift+Up – increases the playback speed.
Fixed Speed Commands
Alt+Shift+Right or the Fast Forward toolbar button – plays the video forward at 8x speed;
Alt+Shift+Left or the Fast Backward toolbar button – plays the video file backwards at 8x speed.
Alt+Up or the Next Frame toolbar button – moves the video one frame forward. If used during playback, stops the video and if repeated moves it one frame forward;
Alt+Down or the Previous Frame toolbar button – moves the video one frame back. If used during playback, stops the video and if repeated moves it one frame back.
If you press and hold Alt+Up or Alt+Down, the first few frames are played one by one in frame step mode and then a normal playback in the corresponding direction is started until you release the keys.
Its a pretty useful way to find the exact frame.
Jump Backwards and Forwards
Alt+Backspace – jumps back 10 seconds (by default) and starts playing forward at normal speed (by default);
Alt+Shift+Backspace – jumps forward 10 seconds (by default) and starts playing forward at normal speed (by default);
Short Jump Back 1 – jumps back 10 frames (by default) and starts playing backwards at normal speed (by default);
Short Jump Forward 1 – jumps forward 10 frames (by default)and starts playing forwards at normal speed (by default);
Alt+Home – jumps to the first frame of the current video file preserving the current playback speed if the file is being played forward;
Alt+End – jumps to the last frame of the current video file and stopping the playback;
The jump interval for the first two commands can be changed from Edit/Preferences/Command Options/Miscellaneous menu.
1 Please note that Short Jump Back/Forward commands doesn't have keyboard shortcuts set by default, but you may assign new shortcuts by following the steps explained in the Keyboard Shortcuts topic.
For quick navigation through the video file you can also use the dedicated horizontal scroll bar at the bottom of the screen called position bar, which can be moved forwards and backwards with the mouse.
Jump to In/Out Cues
Alt+Num Enter – jumps to the current in-cue position preserving playback speed;
Alt+Num Ins – jumps to the current out-cue position preserving playback speed;
Scroll Lock – Pressing the Scroll Lock keyboard button synchronizes the text and the video material. Using this command defines whether in Edit mode the video will be independent from the text or when navigating through subtitles the video preview will be set to the in-cue frame of the current subtitle. In the latter case, by changing subtitles with PgUp and PgDn the user will move through the video material as well (of course, the command is meaningful only if subtitles already have in-cues and out-cues).
There will be a "SYNC OFF" indicator in the upper right corner of the video window , if the video synchronization option is currently disabled.
