Fade black flash
by Camille Harang 25 Jun '21

25 Jun '21

Hello, when I put a fade in the title video effect (here the white "Hello" text https://www.youtube.com/watch?v=dJLj0w6NUSo) you can see that letters appears as a black flash briefly in the first few frames, then goes back to transparent, then the fade starts normally with the white color. Does anyone know how to fix this? I have the same problem when using transparent PNG images with fade video transitions, first black, then normal transparency. Thank you very much, Bests, Camille.

hdmi capture card (with v4l2)
by Andrew Randrianasulu 24 Jun '21

24 Jun '21

A bit on pricely side... (~900 usd) but in theory should be supported by out-of-tree v4l2 (gpl2) driver.. https://github.com/aja-video/ntv2-v4l2 https://www.aja.com/products/kona-hdmi === Features 4K/UltraHD/2K/HD/SD up to 50/60p 4x full-size HDMI inputs each with 8-channel embedded audio HDMI 2.0 (port 1 & 2) and HDMI 1.4b (ports 3 & 4) RGB 4:4:4 12-bit, YCbCr 4:2:2 10-bit and HFR workflows supported Simultaneous capture of 2x 4K/UltraHD or 4x 2K/HD Capture stunning HDR from cameras, game consoles, and more PQ, HLG, HDR10 and Dolby Vision Support* HDR Metadata Capture Video4Linux (V4L2) and DirectShow support Compatible with leading creative apps such as Telestream® Wirecast®, vMix® and more ==== of course it will be interesting to know if such card/driver actually work with CinGG's v4l2 capture implementation....

Cannot render above 60FPS
by gorge rankin 21 Jun '21

21 Jun '21

Hello, I cannot seem to figure out how to render video over 60FPS. I can do 60 FPS and below with no issue. Everything is rock solid stable and very performant. I am using Cin gg latest on Ubuntu. My source video is 2560x1440 at 90FPS. What I've been doing: - start new project - Settings -> Format, manually type 90.000 in "Frame Rate". Ensure that 2560 and 1440 are in Width and Height accordingly. Then I click apply, then click OK. - load my file through resources. right click on thumb of my video in resources, and choose "match all". Then when I render my project with "File Format" of "FFMPEG" and "type" of "mp4" I get these error message windows/errors: One error window with: ------------ "Couldn't open /path/to/outfile.mp4" ------------ and another window titled "Cinelerra: Messages" with this in it: -------------- int FFMPEG:open_encoder(const char*, const char*): check_frame_rate failed /path/to/outfile.mp4 --------- Am I doing something wrong? Thank you in advance.

Any chance of adding FFMPeg's 'atempo' filter ?
by gorge rankin 20 Jun '21

20 Jun '21

I'm still learning Cin, so if this filter is already in place, then I apologize. FFMpeg has a nice audio "filter" called "atempo". https://ffmpeg.org/ffmpeg-filters.html#atempo This filter is already in other projects, such as Kdenlive and Shotcut. What it does is, you can speed up audio, and will adjust the pitch so that the audio sounds more normal, but faster. It does not sound like "Alvin and the Chipmunks" :) This behavior can be seen when you watch a YT video, click the gear icon, and select a speed greater or less than 1. I'm attaching the FFMpeg sample code that I had modified/played with years ago when I was learning it. I 'tweaked' it today, so it will compile in Ubuntu 21.04 using a c++ compiler. I used Qt. There's depreciation warnings and this certainly isn't production code. But it should help others to grasp the concepts to implement it. My Qt pro file has this: TEMPLATE = app CONFIG += console c++11 CONFIG -= app_bundle CONFIG -= qt SOURCES += main.cpp LIBS += -lavcodec -lavformat -lavutil -lswresample -lasound -lavfilter -lasound I put an Option 1 and Option 2 in the main.cpp file. Option 1 simple writes your infile - no modifications to out.raw. Option 2 applies the atempo filter. So comment and rebuild accordingly. It should only take 2 seconds or so to compile. I'm hoping, that perhaps someday, I can simply drop an effect onto my timeline so that I can speed up video/audio in one go and have nicer sounding audio for my needs. Thank you in advance for your consideration.

mxf muxing presets
by Andrew Randrianasulu 20 Jun '21

20 Jun '21

https://trac.ffmpeg.org/ticket/5068 according to this you can mux baseline profile h264 into mxf Also should be supported: dv video (with better 4:2:2 subsampling) mpeg2 (not sure about GOP size?) Avc-intra 100 (intra-only variant of h264 with yuv422p10le colorspace, 100 mbit/s) audio is pcm, 16 or 24 bit please try? put mxf_pcm* into ffmpeg/audio and rest in ffmpeg/video, try to render those and see if other NLEs or tools accept those files...

mpeg1 and mpeg2 in mov
by Andrew Randrianasulu 19 Jun '21

19 Jun '21

You can observe here interesting discussion.. https://video.stackexchange.com/questions/17531/are-mp2v-and-mpgv-valid-mpe… while mov standart not allowed mpeg2 in mov, it also not disallowed it, and apparently some Apple software used such combination... (may be because writing full muxer/demuxer for mpeg was time consuming? speculation...) I added those two as formats, but then not sure how many software will play them (but we never know until we try! Uplayer for Andoid eat them..)
