If you're using a decent Cineform from the GoPro, it might be pretty decent to work with, but the Canon. ![]() depending on which format/codec you're using for the GoPro and the DSLR, you could be dealing with long-GOP media, which especially in 4k is hard on the CPU for playback while editing. ![]() NOT what I wanted! So I made a preset that (besides converting to CFR) 1) keeps the original media frame-size and 2) uses the "Placebo" quality settings so that the bitrate I get out is nearly exactly what went in. In Handbrake, on the Video tab, set it to CFR and also select a specific number frame-rate to get CFR out.Īs another Handbrake note, it looks at my phone's 4k/49Mbps media, and the preset it chose initially would convert that to 1920/1080 at around 18Mbps. Makes it easier for the camera to record smaller files, but keeping that video in sync with the audio (which is recorded at a constant sample rate) in PrPro is not going to work well.įor that, the main suggestion around here is to download/install Handbrake, and use it to convert your phone/device/screen-recorded media to constant frame rate (CFR) before (as noted above) importing or ingesting into PrPro via the Media Browser. ![]() variable frame rate, meaning that although you may have the camera set for say "30fps", what it records will vary between a range of 18fps to 32.4 fps, depending on how much 'detail' of the image is changing per frame.
