I tried to create one just for testing, it apparently saved in .bcast5/Cinelerra_rc, but you hopefully can copy/paste those lines via text editor... http://www.g-raffa.eu/Cinelerra/HOWTO/rendering.html "The Render profile box is there for your convenience. It helps you by keeping note of your favourite rendering settings. You can use it, for instance, for memorizing the rendering of the video stream when you render for DVD. Let’s try it. Select YUV4MPEG Stream as File Format. Click on the Render video tracks checkbox. Select Insert nothing as insertion strategy. Type DVD video stream in the Render profile box. *** - I missed this step initially, silly me! Click on the Save Profile button. Now, change some rendering settings, just to mess things up. Open the Render profile drop down menu by clicking on the arrow on the right side of the Render profile box. Select the DVD video stream option you have just created and… voillà! You get all your settings back!" as far as I can see you can save more than ffmpeg settings this way (from my experiment) : RENDER_1_PROFILE_NAME h264-8bit RENDER_1_FILE_PER_LABEL 0 RENDER_1_LOADMODE 3 RENDER_1_RANGE_TYPE 3 RENDER_1_PATH /data/data/com.termux/files/home/h265.mp4 RENDER_1_FORMAT 33 RENDER_1_USE_HEADER 1 RENDER_1_FFORMAT mp4 RENDER_1_FF_FORMAT_OPTIONS RENDER_1_AUDIO 1 RENDER_1_VIDEO 1 RENDER_1_AUDIO_CODEC h264.mp4 RENDER_1_VIDEO_CODEC h265-10bit.mp4 RENDER_1_AMPEG_BITRATE 256 {...} so may be we can create few of those profiles too and ship them) {i misnamed my profile as you clearly see - it named h264-8bit yet encoder set to h265-10bit! so better to make those NOT at 3 am! }
