Can ver 2.7.1v2 Export Multiple Video Freeze Frames as Jpeg(s)?
« on: February 28, 2019, 03:44:46 PM »
Hi,

Could not find an answer to my question in the Forum, "Can ver 2.7.1v2  Export Multiple Video Freeze Frames as either a single or multiple Jpeg(s)? so Googled and found "Taking Freeze Frames from Video and Exporting as Jpeg"  (had problem trying to post when included url but if want can provide) where Keith Walters mentions "The older versions (Avidemux 2.5) also allowed you to mark a section of video and save it as a series of JPEG stills, but they discontimued that in the later versions."

Can ver 2.7.1v2 do this?  If yes please explain how.

Also appreciate any tips saving a frame(s) as JPG.

Thanks

Ken

Does https://github.com/mean00/avidemux2/blob/2.7.1/avidemux/winInstaller/ChangeLog.release#L24 answer your question?

As you speak about 2.7.1v2, you probably use Linux, not Windows. Anyway, you are much better off using the latest nightly, not the 2.7.1 release. If you are on Linux, you get the best experience if you compile yourself from source (use the ffmpeg4x git branch).

The feature resides in File --> Save as Image --> Save Selection as JPEG. It outputs max 9999 frames from the beginning of the selection (the default selection is the whole video) as JPEG images.

Hi eumagga0x2a,

Thanks for the link! "Add feature to export selection as JPEG images</td></tr>"  Yes it does answer my question.

"As you speak about 2.7.1v2, you probably use Linux, not Windows"  Am using Windows 7 64-bit.  Got the 2.7.1v2 from the Avidemux Main Page website latest news.

As a beginner, thanks for adding "The feature resides in File --> Save as Image --> Save Selection as JPEG. 

Question: Is there a guide/tutorial as to what options (and keyboard shortcuts) there are for the export JPEG images feature?   Am wondering if can use the standard clip cut  A & B?  Was also told that key board short cuts [ for A and ] for B but have not tried yet.

Checked YouTube Avidemux Tutorials, nothing.  Also Googled using keywords    avidemux guide/tutorial as to what options (and keyboard shortcuts) there are for the export JPEG images feature   and restricted to last year also nothing  (Did find "Avidemux Tutorial: Everything You Need To Know & More")

Thanks again for your help!!!

Ken

"2.7.1v2" refers exclusively to appImage for Linux which had to be re-released with modified packaging (no code changes). There is absolutely no "2.7.1v2" for other operating systems.

Whatever, I strongly recommend using the latest nightly instead of 2.7.1 which has got long in the tooth.

There is nothing more that you see in menus, i.e. there is no keyboard shortcut for exporting selection as a series of JPEG images, just Ctrl+E to save the currently displayed frame as JPEG. Please note that in order to save it with video filters applied, not only the video encoder should be changed away from "Copy" but also the toolbar button to enable filtered output should be clicked.

There is no other way to specify selection as to set A and B markers, so yes.

Either these or switch to alternative shortcuts in Preferences to use "I" for the A marker and "O" for the B marker (alternative shortcuts can be modified by editing the configuration file config3 while Avidemux is not running, there is no UI for that).

I think just exploring the application is more promising. Most documentation and tutorials originate from the bygone era of Avidemux 2.5.x. For the current version, the source code is the best and, unfortunately, often the single source of information.

eumagga0x2a,

Thanks again for your detailed explanations!!!  As a Avidemux beginner it Really makes a difference!

"I strongly recommend using the latest nightly instead of 2.7.1" 

Finally noticed "Nightly automated builds available on avidemux.org." at top of page under Misc

Checked http://www.avidemux.org/nightly/win64/   and noticed every few days there is an update. 

Question:  What is the difference between the vsWin64 and win64 Folders?   Googled using keywords      difference between the vsWin64 and win64 Folders  but got nothing relevant.  Did find VideoHelp  Software » Video Editors » AviDemux 2.7.1 / 2.7.1 190225 Nightly  It does list "Complete Version history / Release notes / Changelog" but I do not have the experience to understand.

Thanks again for your help!!!

Ken

Actually, the word "nightly" in my first answer in this topic, consisting of just 4 sentences, is a link, if you haven't noticed it yet  8)

"vsWin64" is for 64bit builds compiled with Microsoft Visual Studio on Windows (of course). "win64" is for 64bits builds cross-compiled on Linux with MinGW. All earlier releases were cross-compiled, the possibility to build an almost feature-complete Avidemux on Windows is new.

eumagga0x2a,

"Actually, the word "nightly" in my first answer in this topic, consisting of just 4 sentences, is a link, if you haven't noticed it yet"  No I did not notice it but your mention got me to look more closely at the download page to eventually find it.

"vsWin64" is for 64bit builds compiled with Microsoft Visual Studio on Windows (of course). "win64" is for 64bits builds cross-compiled on Linux with MinGW.

Forgot to ask which one do you recommend? 

Thanks again for your patience and help!!!

Right now, win64 may be preferable because ongoing work kept VC++ builds from being refreshed since a couple of weeks. In doubt, try both.
