    Suggested Modifications For Handling Fades & Transitions

    Hi

     

    I’m not sure if this might help or cause more confusion, but….

     

    Functional and ‘bug’ issues with Fades and Transitions in PS have been discussed for some time and I guess everyone has their own views as to how they would like them to work.  The purpose of this post is to outline proposals that include some changes/modifications to the way Fades and Transitions are handled by Studio to assist with:

    • resolving at least some of the issues as far as possible

    • aligning the Fade and Transition processes with the purpose of the existing Timeline Modes

    • providing users with more control over maintaining sync on all tracks or overlapping video clips (with video or pictures) to achieve smooth fade/transition of video and audio

    • provide more flexibility and improve editing workflows


    Basically, the concept proposed is that Fades and Transitions should be ADDED/APPLIED, EDITED, REMOVED, RIPPLED based on the Timeline Mode selected with some necessary ‘exceptions’.

     

    For anyone interested in more details or providing input, additional suggestions for handling Fades and Transitions in specific situations are outlined below.  The overall concept is outlined rather than trying to identify only changes which could be messy and confusing.

     

    The intent is to provide ideas for how the processing of Fades and Transitions in PS might be improved; there is no attempt to specify the ‘how to’.  The suggestions are based on PS21 functionality because PS22 appears to have introduced some additional issues that still need to be addressed (the concept may require customisation if necessary to fit with what PS22 is trying to achieve).  Perhaps, after some feedback, adjustment and consensus the suggestions could be updated and sent to Corel for consideration as a ‘guide’ for future development or if more appropriate submitted as an enhancement request.

     

    Fades and Transitions should provide a smooth transition (video and audio) from one Clip to the next, without the need for pre-trimming video clips or significant additional editing.  To do this for video, in most cases, the Clips need to overlap which shortens the Timeline and can lead to the tracks becoming out of sync:

    • Extending a video clip as a ‘still’ image maintains sync but generally results in unwatchable, stop/start video with audio blanks/spikes that requires significant editing to correct.

    • Use of pre-trimmed content may or may not be appropriate for a number of reasons, however, at times still images (either pictures or extending a Clip as a ‘still’ without audio) can be useful.

    • In some situations it may be preferable to lose a small part of the end and start of video clips rather than a larger portion of one Clip.  

     Once added to the Timeline, Fades and Transitions function generally in a similar manner and could share the same EDIT and other associated functions.

     

    NOTE: For the purposes of this document ‘Clip’ refers to any video clip, scene, picture, title, audio file, etc unless otherwise stated. 

     

    1. ADD Fades & Transitions To The Timeline

     

    Fades:

     

    Three types of Fade are proposed and may be added to the Timeline by:

    - Fade OUT: fold back (left) end of Clip on the Timeline.

    - Fade IN: fold back (right) start of Clip on the Timeline.

    - Fade CENTRE: by appropriate method such as drag cursor DOWN at start/end or between Clips on the Timeline.

     

    Fades are applied based on the selected Timeline Mode outlined in Points 2 & 3 below.

     

    When a new Fade is added, folding is limited to the maximum duration as per the default duration for Transitions in the Common Settings.  Use of the ‘Alt’ key when folding overrides the default duration to allow a longer Fade.  The duration of an existing Fade may be later increased or decreased by freely folding or Right clicking to EDIT.  During folding, a pop-up counter displays the adjusted Fade duration (Time:Frames).  

     

    Transitions:

     

    Transitions are added to Clips on the Timeline using a variety of methods including either:

    - Right Click a Clip on the timeline > Add either an ‘OUT’ or ‘CENTRE’ or ‘IN’  Transition to the Clip, or

    - Select multiple Clips on the Timeline (bordered with Orange) and Right Click > Add either an ‘OUT’ or ‘CENTRE’ or ‘IN’  Transition to each selected Clip, or

    - ‘Drag’ Transition to a Clip on the Timeline, as per Dynamic Transition Length setting.  If near end, add OUT Transition; near start, add IN Transition; at mid-point, add CENTRE Transition, or

    - ‘Send to’ from the Library or Transition Tab to a Clip on the current Default track of the Timeline – if the scrubber is placed over a Clip near end, add OUT Transition;  near start, add IN Transition; at point between two Clips, add CENTRE Transition.  If scrubber is not over a Clip that can accept a Transition then display warning that Transition cannot be added.

     

    Transitions are applied based on the selected Timeline Mode outlined in Points 2 & 3 below.

     

    Transition duration is as per the default for Transitions in Common Settings or if placed onto another Fade or Transition of the same type (IN, OUT, CENTRE) the position and duration of the original is applied.  The duration of an existing Transition may be later increased or decreased by dragging the edge or Right clicking to EDIT.  When adjusting the Transition by folding/dragging on the Timeline a pop-up counter displays the adjusted Transition duration (Time:Frames).

     

    NOTE: There appears to be an intermittent bug in PS21 when the Timeline is zoomed out to about 1 Min or more (more Clips visible) the Fades/Transitions are sometimes removed or a different duration to that input in the Editor is applied for no apparent reason.

     

    2. OVERWRITE Mode

     

    Add Fades and Transitions to Clips on the Timeline using the preferred/appropriate method and apply them in a manner consistent with Overwrite Mode as follows:

     

    - OUT Fade/Transition: ‘Freeze frame’ the current first frame of the incoming Clip for the duration of the Fade/Transition.

    - IN Fade/Transition: ‘Freeze frame’ the current last frame of the outgoing Clip for the duration of the Fade/Transition.

    - CENTRE Fade/Transition: ‘Freeze frame’ the current last frame of the outgoing Clip and first frame of the incoming Clip equally.

     

    The ‘Freeze Frame’ portions are highlighted a distinctive colour.

     

    If the end/start of the Clip is later trimmed, automatically remove the ‘Freeze Frame’ and revert to the original Clip.  To maintain the length of the Timeline use any pre-trimmed portion and/or extend the original end/start points as ‘Still’ and highlighted ‘PINK’ to accommodate the Fade/Transition without altering the Clip duration.  If required, a ‘Freeze Frame’ may be re-applied by Removing the Fade/Transition and adding a new Fade/Transition at the new start/end point.

     

    When ‘dragging’ a Transition to the Timeline while in Overwrite Mode, the ‘Alt’ key forces Insert Mode.

     

    Where there is no adjacent Clip, to enable Fade or Transition over the previous or next Clip on other tracks, IN and/or OUT Fades and Transitions can be added to the start/end of it as appropriate.    Sync rules apply as for Overwrite mode.  The Clip on a track below that is overlapped (including audio) is not altered and sync is always maintained.

     

    When a Clip is Removed, if there are adjacent Fades and Transitions involved, all Fades and Transitions associated with it are removed and the gap is NOT closed.  (There appears to be a bug in PS21 whereby remnants remain on the Timeline if a clip is removed where OUT and IN Fades are adjacent to each other, however, for Transitions with a similar scenario removal of Clips appears to work correctly).   

     

    The length of all tracks is maintained and all tracks are always kept in sync in Overwrite Mode.

     

    NOTE: If required, any PINK portions can be trimmed out later using Insert or Smart Mode.  To tweak the end/start of the Clips use Overwrite Mode so the Timeline length is maintained and sync issues avoided.

     

    3. INSERT and SMART Modes

     

    Add Fades and Transitions to Clips on the Timeline using the preferred/appropriate method and apply them in a manner consistent with Insert or Smart Mode as follows:

     

    - OUT Fade/Transition: Overlap/shorten incoming Clip.

    - IN Fade/Transition: Overlap/shorten outgoing Clip.

    - CENTRE Fade/Transition: Overlap/shorten both Clips equally.

     

    The Clips are overlapped by the amount required for the Fade/Transition from the current start or end point(s) of the Clips as appropriate to accommodate the smooth fade/transition of video and audio over the required/default duration and the track length is shortened.  There are no ‘still’/’Freeze Frame’/PINK portions created and any pre-trimmed portions of clips are disregarded.  If pre-trimmed portions are required later the Clip may be Trimmed as appropriate in either Overwrite, Insert or Smart Mode as appropriate.

     

    When ‘dragging’ a Transition to the Timeline while in Insert or Smart Mode, the ‘Alt’ key forces Overwrite Mode.

     

    When adding or editing a Fade or Transition on a Clip, to sync tracks as far as possible, prompt for an option to:

    . 1) shorten same track only, or 2) shorten this Clip only, or 3) sync other tracks (except if locked)

    . For Option 3 - sync other tracks - where the next A/V content on other tracks, including detached audio track(s), commences at the Fade/Transition insert point or to the right of it, automatically insert a Trim Point on each track where appropriate and pull back the content on those tracks by the number of frames the Clip(s) was/were shortened for the Fade/Transition (to maintain sync as far as possible).  Any Clips spanning the insert point are ignored and need to be adjusted manually. 

     

    If multiple Clips are selected add the Fade or Transition as for ‘Ripple’ described below.

     

    NOTE: The user has the additional option to simply lock other tracks as required to avoid any changes to them.

     

    Where there is no adjacent Clip, to enable Fade or Transition over the previous or next Clip on other tracks, IN and/or OUT Fades and Transitions can be added to the start/end of it as appropriate.    Sync rules apply as for Overwrite Mode.  The Clip below (including audio) is not altered and sync is always maintained.  NOTE: This situation is an ‘exception’ to the Insert Mode process.

     

    Where a Fade or Transition is added between a Video Clip and a Picture the audio in the video clip should fade in/out as appropriate.

     

    When a Clip(s) is/are Removed, if there are adjacent Fades and Transitions involved, all Fades and Transitions associated with it are removed and the gap closed (There appears to be a bug in PS21 whereby remnants remain on the Timeline if a clip is removed where OUT and IN Fades are adjacent to each other, however, for Transitions removal of Clips appears to work correctly).

     

    NOTE: If required, any pre-trimmed portions of Clips can be added back later by trimming the Clip in Insert or Smart mode.

     

    NOTE:  In some cases a ‘still’ might be suitable, in such cases the user simply activates Overwrite mode to auto apply a ‘Freeze Frame’ at the current end or start point.

     

    If a clip/scene/picture is too short then apply Fade/Transition to available length and display an appropriate warning message….’Fade/Transition duration reduced’ or ‘cannot be applied’ 

     

    4. EDIT Fade or Transition

     

    Either Drag/Fold the edge of a Fade or Transition on the Timeline. The pop-up counter (Time:Frames) displays the adjusted Fade/Transition duration.  Alternatively, right click Fade/Transition to open the Editor.  An additional edit option to select one or more Clips and ‘Remove ‘Freeze Frame’ or ‘Revert to Original’ could be useful.

     

    If a Fade or Transition is replaced by another Transition the position and duration of the original is applied.

     

    Fades/Transitions may be ‘Removed’ by type (IN, OUT or CENTRE) from one or more selected Clips (bordered with Orange) or individually set to zero by EDIT or ‘folding’.  Removal is applied based on the selected Timeline Mode (Points 2 & 3 above).

     

    5. RIPPLE Fade or Transition

     

    Fades and Transitions are Rippled based on the selected Timeline Mode.

     

    If Timeline is in OVERWRITE Mode add the ‘matching’ Fade/Transition to the selected Clips.  Create a ‘Freeze Frame’ at current end/start point as appropriate and highlight the ‘Freeze Frame’ portion a distinctive colour.   Generally as per Point 2 above.  If an existing Fade or Transition is encountered replace it and use the duration of the original.  The Timeline length and sync are always maintained.

     

    If Timeline is in INSERT or SMART Mode add the ‘matching’ Fade/Transition to the selected Clips.  Overlap the Clips from the current end/start points as appropriate to suit the type of Fade/Transition.  Disregard any pre-trimmed portions.  Display warning if any clips too short or Fade/Transition was not added to all Clips/Scenes/Pictures.  Generally as per Point 3 above.  If an existing Fade or Transition is encountered replace it and use the position and duration of the original.  There is no attempt to maintain sync with other tracks.

     

    NOTE: If required, adjusting other tracks to maintain sync when Rippling would require a process to automatically add Trim Points where appropriate on other tracks after inserting each individual Fade/Transition in the ‘Ripple’ to pull back content on each of those tracks to try and maintain sync.  It appears this would be very complex and the number of components spanning each insert point could potentially be numerous….it would probably not be possible to auto adjust these components.  Due to complexity it would probably be necessary adjust all other tracks manually after the Ripple has completed.

     

    NOTE: It is recommended that Rippling is used early in the editing process and if possible before content is added/moved to multiple tracks to reduce the amount of editing required. 

     

    6. Pictures

     

    Using the methods above, Pictures could be handled as for video.  This would mean that the start/end of a picture would be ‘Freeze Frame’ when Fade/Transition applied in Overwrite Mode which would be useful in situations where, for example Pan & Zoom, the zoom would not start until the Fade/Transition is complete at the start or stop prior to the Fade /Transition commencing at the end.  When a Fade or Transition is placed between a video Clip with audio and a Picture the audio should fade in or out as appropriate. 

     

    NOTE: If using Insert or Smart modes it may be necessary for the user to slightly increase the default duration for Pictures in Common Settings as the duration will be reduced by the overlapping.
