Short description of error
I am editing video via the Video Editing screen. My source video has 29.97 fps. The appropriate frame rate is selected to make sure video and audio is synced. Edits are made to the video and fade-in and fade-outs are added. Total video length is 2:15:58. Rendering at 720p with 6000 (2000 also tried) bitrate produces a video with 244 frames/second instead of the 29.97. When a smaller segment of video is rendered, the final render is the correct 29.97. Only when the full length is render does Blender produce the 244 frame rate.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Imported video; made soft cuts to video and audio resulting in 2:15:58 length; added fade-out then fade-in layers at cuts; render presets selected as 720p; resolution size set to 100%; display dropdown selected to "Keep UI"; Output tab: MPEG selected, format: MPEG-4; Codec: H.264; Bitrate: 2000 and 6000 attempted; Audio: MP3; Click "Animation"
