movie-screenshots: fixed number of shots for mutliple movies
Posted: Wed May 21, 2008 1:51 pm
The most important for me is the screenshot tool "extract film frames" (I use the german version so I`m not 100% sure what the english name of the funtion is).
This feature could save a lot of time if it would work a bit smarter.
What it does is extracting all frames in the movie file which takes a lot of time/CPU power and drive space.
Even deleting the unwanted files takes time.
That`s why I never use it. I manually save screenshots with GOM-PLayer instead.
What I would like XnView to offer is this:
Automatically generating a limited number of screenshots for one or more selected movie file(s).
I would like to be able to specify either a fixed number of frames or a time-interval between frames to extract. I suppose I would mostly use the time interval option.
If a movie is 90 minutes and I select 1 screenshot per 20 seconds, XnView would save 270 screenshots as jpgs.
I assume that using keyframes with roughly the selected step-length rather than strictly using the selected step length would make this faster (especially for mpeg-files).
So maybe there sould be a little checkbox for the user to select.
With the "fuzzy" method the tool could chosse maybe frame #207 which would be a keyframe instead of using frame #200.
details:
I would like to select any number of movie files or *folders that contain movie files* of which I want screenshots to be generated.
The default saving position for the screenshots could be the folder of the movie file but it would be great to optionally get a sub-folder named after the movie file or "screenshots" or whatever the user wants.
I would also like to be able to select movie after movie, specify individual save folders for the screenshots for each movie file and then let it run as a batch-job.
That would be such a great help!
ps:
To make it perfect the tool could display the assumed filesize the the generated screenshots will probably take on the harddrive. This last feature is not too important in most cases though.
