Check to see if there is an option to allow variable frame rates.
#48 frames per second audio dsync mp4#
Your Possible Solution: When you take the raw audio and video files and convert them to a single MP4 file, the program you are using may not be handling the variable frame rate properly. Thus the computer knows to insert frame/image 2 at a certain time in the recording and hold that frame/image until the time code comes for frame/image 3. So if its 44Khz, 16 bit, change it to 48KHz, 16 bit, and. Instead of having the video and audio tracks the same length, in variable frame rate both are now synced to a time code track. Ive found a temp fix is to change the default format of your primary audio device under properties. same problem (audio is out of sync until I turn off Match Frame.11 answers Top answer: There is no current solution other than turning it off. Layer-2, encoder complexity is moderate and decoder. Im talking about how sound is almost a quarter of a second early when. The audio is behind the video about 1-2 frames per second every 5 minutes and that.50 posts Hey everyone, my setup is: Sony a6500 on 50fps 48Khz connected to HDMI 1 on the Atem Macbook. If there was constant motion, like on TV, then you need to capture a new frame 29.97 times per second to create smooth movement, but in GoToWebinar, typically the same image/slide stays on the screen for many minutes, so capturing the image once every second would suffice and would result in a much smaller file size. The basic frame length is 24 ms (at 48 kHz sampling frequency), corresponding to 1152 time samples. Mic connected to Mic1 on Atem with 2 Frames Delay.
Normal frame rate (number of separate images per second) for television video in the USA is a constant 29.97 frames per second.
