Source files are interlaced, constant 25 fps, lossless ff1v 3.4, yuv 4:2:2 with pcm_s16le 48kHz audio. Below is an example of trimming a 20-second clip from the 100 second mark 3.I am editing some old homemade videos and I would like to split the files (~2h long, 60 GB) to smaller chunks ~10-15 min long for archiving on different media.Ĭurrently I am testing merge/concatenate of the files (segments) back to the full length video (source). You can use FFmpeg to trim footage off of the beginning and end of your video. Also, you can do this for free without purchasing any software! Trimming Footage These tips require the command-line, but if you can get past that barrier, you’ll be able to edit your videos without long rendering times and quality downgrades. To fix this, I did some experimenting with FFmpeg, a command-line based video processor, and found a worflow for editing our let’s play without re-encoding. I knew that after YouTube transcoded the videos for it’s internal format, the final output would look even worse. Futhermore the output videos had significantly lower quality due to the re-encoding. Rendering the 1080p/60fps videos was taking upwards of an hour. When it came time to edit the videos, I fired up Adobe Premiere 2, but quickly ran into a problem. Audio commentary was recorded separately in Audacity. It was recorded using Dxtory with the x264vfw codec, meaning that the saved recordings are H.264 streams in an AVI container 1. I recently worked on a Lego Island 2 let’s play with my brother.
