The Mainconcept or Sony codecs in Vegas are subpar for low-bitrate output such as needed for HTML5 use. Use ffmpeg to generate your HTML5 videos. Yes, mono audio is acceptable for HTML5 use, but once you use ffmpeg/x264 for generating those videos, the 6kB/s savings you get from switching to mono audio won't matter much if at all. Get the 32-bit static ...


I don't believe there is. You could create a very long file that repeats the video a couple of times. Alternatively hook up a raspberry pi, or a tiny pc to do the job.


At least on FFmpeg 2.8.x (but oldie should works too) you can use lavfi as input format and complex filter graph using movie and setpts filters as a argument for -i option. Next command doing this work for you: ffmpeg -re -f lavfi -i "movie=filename=input.mp4:loop=0, setpts=N/(FRAME_RATE*TB)" output.mp4 Zero loop= arguments means infinity loop. Values ...


If I understand you correctly, you want the MOOV atom to be stored at the end of the MP4 (after the media payload). If so, this is the typical scheme used by ffmpeg unless flagged otherwise. So, copy your current MP4 into a new container via ffmpeg: ffmpeg -i input.mp4 -c copy output.mp4


Import the file into the project media box, I right click the video and go to orientation change it to 0 (original) Should render without any problems.


From your post I am not sure why Resolve wont recognize your files...but you should transcode your footage anyways before ingesting into Resolve. Even if you start with highly compressed source media, you should transcode to something less compressed, and that will put you in 4:2:2 at least vs working with 4:0:0. ProRes or DNxHD codec will give you files ...


mp4/h264 files are super compressed files and require a lot of horse-power to read. that's why a lot of machines and programs have trouble with them. also, they suck if you are trying to do precise synch-based work. work with proper codecs, ProRes or DNxHD.
