Subtitling > Video Playback

Overview

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 navigate 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.

Frame-by-frame playback

Pressing and holding the above commands will at first play the video frame-by-frame but after a while will switch to normal playback speed forwards or backwards, depending on the particular command. Releasing the buttons will pause the video.

Jump to Fixed Position Commands

Jump Backwards and Forwards

Alt+Shift+Backspace	Jumps forward 10 seconds* and starts playing forward at normal speed.
Short Jump Back**	Jumps back 10 frames* and starts playing backwards at normal speed.

Alt+Home	Jumps to the first video frame of the video, preserving current playback speed, and continues playback from there.
Alt+End	Jumps to the last video frame and stops the playback.

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.

* - The exact Jump interval can be modified from Edit/Preferences/Command Options/Miscellaneous.

** - The two "short jump" commands don't have keyboard shortcuts assigned by default. Go to Tools/Customize/Commands to assign them shortcuts.

Jump to In/Out Cues

Alt+Num Enter	Jumps to current in-cue position preserving playback speed and continues playback from there.
Alt+Num Ins	Jumps to the current out-cue position preserving playback speed and continues playback from there.

Synchronizing Video with Subtitles

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.
