VideoFritter, a video preprocessing tool for lossless clipping.

VideoFritter

VideoFritter is a free and open source .NET Core 3.1 based WPF Application that provides a convenient UI over ffmpeg for exporting shorter clips from videos without quality loss. It is especially useful for preprocessing large video files, e.g. getting rid of boring parts or camera shaking at the end or the beginning.

The playback is implemented via the WPF MediaElement control (i.e. a Windows Media Player), therefore it uses HW acceleration (if supported by the OS). The export functionaly is using ffmpeg in lossless mode, therefore it's quite fast since it does not encode, but just copies files.

VideoFritter supports video formats, resolutions and codecs which are supported by both ffmpeg and Windows Media Player, e.g.: avi, mov, mp4, H264, H265, FullHD, 4k, etc.

The latest Release can be downloaded from the Releases page.

videofritter's Issues

Give comment to segments

Add possibility to give a comment (text) to the defined segments, in combination with #3 so that one can persist the description/identification of the segment for later processing.
It is beneficial, as for the flittering one have to watch the video, and anyhow have to take the notes about the subject, etc, for the final edit.

Only audio, video and subtitle streams are copied

Only audio, video and subtitle streams are copied, other streams like sensor (GPS, gyroscope) data streams are not.

See issue #1 and this stackoverflow question about the root cause.

Cannot perform export

Whatever section of the video is selected, cannot perform expert, as throws this exception:

My educated guess, may be related to Ryzen and built in graphics vs. ffmpeg.
The playback of video is smooth.

Using standard GoPro Hero5 timelapse recording, only video, no audio.

Purpose of the volume control

What does Volume control for? What volume does it control?
The system volume is 100%, but it shows ~50%, it is a relative volume?

From standard interaction point of view:

• It does not show any value at tooltip,
• No mute option for volume at the control

May be consider removing it if concluded to be not required.

Precision of step navigation

Step (forward/backward) goes by 100 ms (not by frame), but by 100 ms.
This means 3 frames for a 30 fps recording (especially at time-lapse this could mean a lot).

How to go in smaller steps? e.g. provide possibility to able to edit the positions manually?

Save and load the export queue

Add the capability to save and load the export queue, so that one can e.g. continue the rough cutting later.

Provide keyboard shortcuts

Add keyboard shortcuts to the controls. e.g. step with the arrows, mark begin/end of segment, etc.
Currently spacebar executed the command the focus is on. But would be better to always do play/pause.

Load segment from export queue

[Open next video] is a good idea, additionally how about adding the following:
when double clicking at the export queue, loading that particular one to the player together with segment configuration?

Cannot save changed preferences

Application installed to the standard/default location.
When trying the save changed setting, the following error happens:

Proposal save custom settings to %APPDATA% somewhere.
