Re: [Cin] Waveform generation using ffmpeg filters
Yes, all right. Thank you. I have not figured out yet how to connect both channels - left and right, but this business is solved. -- Ugin. 13.04.2019 17:47, Phyllis Smith пишет: Ugin, GG says that using F_aeval is easier.

[Cin] Waveform generation using ffmpeg filters
Hello. I'm trying to generate a 440 Hz sound with the help of FFmpeg of ffmpeg -f lavfi -i "sine=frequency=440:duration=5" test.wav type, but the waveform is: https://www.datafilehost.com/d/ea27d7ec Does Cinelerra incorrectly process the generation, or do I need to change something in the settings?

Re: [Cin] Proxy error (optimal settings)
Me: "2) to convert the fps inside Cinelerra-gg, like I have done with your 61 fps video: in Resources->Media, select the video, RMB on that video, choose "Info" option and change video's framerate." (I think, you always know) Keep in mind that if you change the fps there, only video fps is changed, not audio. Then you lose the A/V sync. Phyllis: "In the Resources window comment field the addition of fps and codec have been added. This has been checked into GIT and is in the latest ubuntu16 build in the usual place." Thanks for all. Could you also add the size WxH information, please? For example 1920x1080@29.97. And add the info for the Audio, if possible. Now it is empty. I guess you can't create a new field for every single info. Sorry for all these requests. IgorBeg -- Cin mailing list Cin@lists.cinelerra-gg.org https://lists.cinelerra-gg.org/mailman/listinfo/cin
