Select start/end points by frame about vidcutter

[ozmartian]

let me know your thoughts on the new v3 release... the only thing missing now is manual frame number entry which will be in the next release...but frame stepping is now there, as best as can be achieved with tools and algorithmic tricks available

[ozmartian]

The arrow keys and mouse wheel is already supported and has been since first release version :-) Do the keys not work for you guys?

The latest version 2.5.0 is now stepping through videos frame by frame for better accurracy.

AS I am too lazy to write documentation, I guess I should clarify the key codes:

• LEFT = Step back one frame
• UP = Step back 10 frames
• RIGHT = Step forward one frame
• DOWN = Step forward 10 frames

MOUSE WHEEL UP & DOWN = Single frame steps

Will be adding a shortcut key for marking cut points while video is playing.

Any other ideas are welcome....

I would love this as well. I was thinking of just moving the arrow keys, or maybe moving those when i.e. holding the shift-key.

Oh ad back to your original request. Did you mean like a small text field whre you can manually enter frame number perhaps time as wll to move to that point immediately? Thats definitely in the works once the challenge of properly reporting frames is solved.

Hi ozmartian,
First of all thank you for the great application. I was looking for something like this for a long time.
If you do not mind, want to propose several enhancements:

• Time format change to be more precise (because step is changed to per frame): from xx:xx:xx to xx:xx:xx:xx

• In time field instead current slider position / total time change to clip start time (frame) / clip end time (frame)

• Time fields can be made editable, time or frame# can be entered manually

• Addition of separate field with constant value of total movie length-time

• Addition of separate field for current time (frame) position

• Addition of Undo and Redo options

@ozmartian
I used when I was on windows system for cutting commercials form video TMPGEnc video encoder.
On linux there is similar only Avidemux app, but problem is when recorded file have eg. more audio and subtitles track and epg tag. Avidemux won't mux all these track in output file only video and one audio track.
Then I found dmMediaConverter but problem is that don't have selection by frame, then always cut too much or too little, it is not precisely.
So I thought to have at least; mark start/end frame and button for cut selected area.
Te best it would be if it possible to have some similar like TMPGEnc, time line video preview frame by frame for easier selection: TMPGEnc video

don't have selection by frame

You are aware of the problems involving GOPs in several codecs (e.g. AVC-HD) so that it is impossible to have frame accuracy in trimming, right? Unless you implement smart rendering, i.e. re-encode the first and last bit of output up to I-frames (and not even all I-frames work, but only some of them).

Smart rendering is hard. You cannot just add a slider or a text box to input the value you want, a software needs to implement GOP parsing and encoding in an extremely accurate way.
