#1 FAQ » Missing output or gui on monitor/projector » 2021-09-09 19:53:52

Replies: 0

This can happen for a number of reasons and I've been confused sometimes due to missing simple things. I'll jot them here as I come across them again.

1: Make sure the output, that is, the 2nd screen to the left of the GUI has been set up correctly in the display manager / nvidia settings / etc, so it sits directly to the left, butt up against, your GUI screen.

#2 Re: FAQ » OpenGL Shading Language (GLSL) is not high enough, why? » 2021-08-12 08:05:39


I'm trying to run vidifold app I can only see the logo, it's written Critical error Requires minimum 4.3 shader version.  Do you know if I can do something to make it work?


It's possible to bypass this check, but it MAY only partially work, if at all. You can run the program from the command line with:

./vidifold 2

If it doesn't work you could also run it in debug mode and send over the debug file with this command.

./vidifold 1

this will create a VIDIFOLD-logfile in the same folder as the executable.


1: this is a plain text file, so you can review what it contains before sending it over.
2: this grows very large very quickly, but shouldn't be a problem for you as its not getting very far.

It will tell us where its stalling.

4th way of loading patch now, click to select and then click on bus preview to drop

I'm not going to bother with the drop onto rack option

Initial investigation: required a dip into the XI2 protocol, although its been around since 2010, there isn't that many examples. Exp since the version I wanted to use is 2.2, which allows multi-touch. I got a little way into detecting the device but not able to use it.

Think I'll just focus on some options to help with the basic touch handling, i.e. using a finger for mouse click, as this doesn't require any new event handling and would be quite useful anyway. I'll probably come back to this in the future.

Note: it is already possible to export/import a sequence of PNG frames.

This ticket is related to exporting/importing video clips with alpha, without any extra process step.

#7 Re: FAQ » Making a music video » 2021-03-06 20:58:13

Another option/workflow based on notes supplied by Jim Ruxton.

He was using this to method to keep audio sync with video taken from phones. I haven't tried this myself but it works for Jim.
Basically running the primary video and audio via a feed and capturing the output via OBS.

1. convert the primary video from 1080 x1920 to 1280 x 720, so it can be used as a feed, top and tail the video with some black frames for the count in/out.

2. start the video by sending video to v4l2 and audio to default sound card ie.

ffmpeg -re -i inputVideo.m4v -map 0:v -pix_fmt yuyv422 -f v4l2 /dev/video0 -f alsa default

3. start OBS to record sound and video from monitor output.

4. Start VIDIFOLD and select/start/and load feed into a slot, manipulate the video till it ends.

5. Stop the feed, Exit VIDIFOLD, stop recording in OBS.

6. Convert video back to 1080 x1920

He says, this gives fairly good lip sync. Not perfect but this is much better than using a clip within VIDIFOLD for this application. It also takes  away the time necessary to process a recording and export it within VIDIFOLD.

#8 Re: Closed » Touch screen behaviour » 2021-03-06 20:41:37

It works, but the GUI isn't designed for it. However I've put touchscreen improvements into the backlog now as I now have the ability test it.

Upgrade export and recording functions to include Alpha if selected

#10 Re: Closed » Whats up with aspect ratios? quality? » 2021-02-28 16:44:40

This has been updated in v0.24.12 and videos/images/feeds have aspect options.

VIDIFOLD doesn't DO AUDIO and I wouldn't guarantee 'lip sync' level of recording, but...

When I've produced 'music videos' with it:

1. I've prepare the audio (normally with an added 5 sec gap on each end) to run via VLC,  and have the interface close by
-- and when ready on VIDIFOLD (loaded up patches and ready for live run through)
2. started recording via 'Configuration & Tools' -> Video Recorder -> 'Start Now' AND as quickly as possible started VLC playback
3. perform the 'JAM'
4. and at or after the end of the audio,  stopped recording via 'Configuration & Tools' -> Video Recorder -> 'Stop Now'
5. WAIT... once the clip has been rendered and placed in the '!Vidifold Renders!" folder, locate and select it and used the 'export' option
6. I then use ffmpeg to attach the audio track to the video

Job done. You can see the results at the bottom of the VIDIFOLD homepage.

I really want to have an audio track loadable and triggered from within VIDIFOLD, with the mix down an option on the export, but it's not working yet and is early days for that bit.

This will be on going for a while but I'll try and improve parts of the GUI so they are more touch screen friendly

#15 Re: Backlog » Umlauts in filenames are not displayed correctly » 2021-02-02 18:26:41

moved to backlog, I think this is required at some point and would involve improving my font rendering system (while there could also speed it up)

#16 Re: Archive » [IMPROVEMENT] allow snapshots with source plugins » 2021-02-01 22:13:37

needs some follow through but system wired in now, v0.24.8

#18 Re: Backlog » Glitch effect bug? » 2021-01-28 20:20:31

think I've seen this now, it doesn't its just the odd frame now and again on my machine, I'll revisit this plugin soon

#19 Re: Backlog » Frame Jumper » 2021-01-27 23:02:44

another option that was mooted, was to have the distance jump be a multiple of the 'wet/dry' eg full step when wet at 100%, half the step when wet at 50% and of course no step when at 0 wet. This wasn't possible before, but with the upgrade I did when I released the plugin API, I think this should now be possible.

#20 Re: Archive » [REQUEST] Outline plugin (not the NeonEdge) » 2021-01-27 22:59:31

I've made a edge detect plugin, hope this does the job, will think about the dilate/erode plugin which would work along side this.
pending release

I really want this but it will take a lot of work to introduce due to the polyphonic auto cross fade built into the buses. I'll keep thinking on this.

#22 Re: Archive » [IMPROVEMENT] Default Mix options » 2021-01-24 14:44:51

these are now available via new layer state buttons next to the bus output preview, v0.26.6
