Got to reviewing the align edits function.  It started as a way to load multiple files & align the audio of each file with the video.  In daily use, it became a convenient way to synchronize editing, since there's no way to lock audio & video tracks.  To make this work, it had to start deleting glitch edits.  Audio shorter than 1/2 as long as the video was classified as glitch edits.

Helas, this causes edits to mysteriously disappear when audio is intentionally less than 1/2 as long as the video.  An improvement would be to count the total number of video edits.  If there are more audio edits than video edits, delete the audio edits shorter than 1/2 as long as their video edits, starting from the shortest. 

If there are intentionally more audio edits than video edits, it'll delete wanted edits.  That's why it still has to keep all edits over 1/2 as long as their matching video edits. 

If there are fewer audio edits than video edits, it won't delete the glitches anymore.  In typical workflows, this may not have happened before.  The typical timeline has the same number of audio edits & video edits easily visible, with a few invisible glitch edits.

What if you want to align just a part of the timeline & the selection has more audio edits than video edits?  Lions never had to do this before, but it would entail pasting silence.

The only time the legacy glitch edit removal was problematic was when the file handler picked up a wildly different length for audio & video or audio files had different numbers of channels.  It only deletes desired edits when artificially forced to.  Lions use it every day with normal files & it's not a problem. At this point, additional counting of the edits seems over complicated.

Locked audio & video

A bigger problem continues to be the lack of a way to lock audio & video.  Other programs treat the audio & video in the same file as a single media type & require extra steps to edit them separately.  

A synchronize function seems to be the answer.  It makes sure the source starts of the audio edits match the source starts of the  video edits.  For cases where the audio & video come from different assets, they could be pasted as a nested EDL to get this function to work.

Lions typically have multiple camera angles & a single audio track rather than multiple clips from different sources with independent audio & video.  Locked audio & video tracks wouldn't work.  A synchronization function would require the source times in every video asset to match the times in the audio asset.  It could be done with nested EDL's, by making sure the nested EDL for every camera angle had the same audio asset but only the video was used.  Then video from every nested EDL would have the same source positions in the audio.

Align edits dialog box

What's probably needed is a dialog box for align edits where the user enables glitch edit removal & synchronization of source positions.  Then the master edits are the top track.  It could be a pain to have to go through this dialog.

What happens if the top track has silence & a track below it has an edit?  The master eventually needs to be the top most edit with data instead of the top most track.  The only case experienced so far has the top track being contiguous video edits though. 

There could be a gap where all the video tracks are silent.  That would cause it to align against the top audio track.  It probably needs a way to just use video as the master & a way to preserve areas of silence.

For now, the existing topmost track as master with options to delete glitch edits & synchronize sources seems to be the answer.  It's going to be a pain to have to go through a dialog box.

Updating effects

Another problem that emerged was keeping effects synchronized after the edits are synchronized.  This is a whole separate alignment problem.  The effects are going to have glitch edits just like the media.  In the past, the solution was not to have transient effects but to have static effects for the entire track duration.

If the align edits function is to be a general purpose synchronization function, it's going to need to align the effects in some minimal way.

There has been an option to edit media without touching effects but no option to edit effects without touching media.  That might be the next frontier.

TODO:

There is a corner case where if silence exists before the next master edit, it won't extend the slave edit.  It'll extend the silence.  This only became noticeable after adding the edit extension option.

This requires a gap removing option which deletes all the silence before aligning.  The mane difficulty in that case is pre-existing keyframes in the gaps would get deleted & not recreated.  Gap removal might actually be required for edit extension to work intuitively, but the keyframe problem requires it to be optional.  That makes ballooning complexity the problem.

The mane question is have lions ever needed a gap removal function & the answer is they never even needed an edit extension option.  In not always
guaranteeing the gap is filled, the edit extension option is more of a toy.

The cradle of love hottie is not as easy on the eyes as 40 years ago.  She's 4 years older than the lion kingdom, dear god.  She was in 1 B movie & disappeared in the 90's.  She was 17 during the summer lions discovered her on KTSF 26.  She was so dominant & arousing on that 45" TV.  There's no going back to when the older ones were more arousing.

What a feeling it must have been to be a 13 year old hugging a 17 year old or even a 16 year old with any intimate relationships.  Lions don't believe most men have any intimate relationships until after 30, if ever, nowadays.  The trend was downward by the 90's because of the declining standard of living & lions were definitely in the middle of the pack, a fly on the wall of limited means. 

Lions won't confirm or deny that Cinelerra was written to get animals hard as fast as possible.  It's just very optimized for moving media onto a timeline, playing back, & getting still photos.

 What lions think is happening is index funds are earning interest on large treasury positions.  They're putting the interest into stonks to manetain a constant allocation.  It's not millennials pouring money in the stonk market expecting lower interest rates. High interest rates are pushing up stonks like the 90's.  Millennials are taking money out of the stonk market to buy houses & pay their mortgages.  Important reminder that lions would only barely get by & be fairly unhappy if they retired now, drained their savings to buy a house, & couldn't afford a lot of things they hoped to have.  Lions don't expect to have the coordination required to play it, when the time comes.  Maybe they could just play chords.  Would definitely have to learn how to tune it & regulate it. If lions didn't have to buy a house, things would be better. 40 years ago, bonds were called fixed income because the standard method was to use interest as a sou...

 Don't kid yourself.  US is a 1 party system.  Unless something is drastically wrong with the 1 campaign, they always vote democrat.  Even as bad as H-Rod was, they still voted for her. Ordering renters to provide $25,000 subsidies to new home owners is basically ordering them to pay what was an entire down payment 20 years ago.  Surely if they could afford these entitlements for home owers, they would have bought houses themselves.  They formerly required the high school dropouts to pay $50,000 in student loan forgiveness to Harvard graduates. Calif* requires renters to provide a $150,000 subsidy to new home owners or about the total cost of a house 20 years ago.    Amerikans just want the Calif* way of life for all.  If you don't like how wealth is redistributed from poor to rich in Calif*, you're not going to like the rest of US. ---------------------------------------------------------------------------------------------------------------...

 Anyways, the next idea was revising the GUI to get rid of the drop shadows, decorations.  The modern trend is flat colors, but the trends have to change every 6 months for these corporations to stay in business. 1 idea that looked good was an apply button in the file dialog which would allow loading files from a bunch of directories or picking 1 file at a time without closing the window.  The trick is most files require building an index.  The file dialog would have to be frozen during the load process or it would have to be locked out of loading again.  It would be a functional but unpleasant experience. The biggest win right now would be repositioning the plugins to the top when there isn't an asset. The lion kingdom considered applying to FUTO for a grant.  The problem is there are so many forks, so many animals who expect a cut even if their contribution never worked, so many animals who would expect a cut for a feature idea in the future which they ...
