Jerky panning after rendering.

[sydhsydh]

I am using APE15. I have a fairly good cam, a Panasonic AG-AC30. I record in MP4 1920 x 1080 at 50 fps. Bitrate is 49790kbps. Playing the MP4 on my PC seems to be fine. There is a very slight stuttering on panning but this I believe to be normal, the faster the pan, the worse stutter, but perfectly watchable.

After I have completed editing I render and save to MP4 H264 1920 x 1080 25fps bitrate 15Mbps. Playing the resulting video either on monitor or TV, there is a very uncomfortable chopping on horizontal and vertical pans and zooms. The faster the pan or zoom, the worse it gets. Unlike the original MP4, the stutter is unacceptable. It is as if several frames are being dropped every second.

Am I doing something wrong? I have never noticed this on previous cams but I'm sure it is not the cam because the original files play OK. I wondered if it was something to do with the 50fps recording versus the 25fps render but not sure. Is it the recording settings at fault, or the APE settings? The recording cannot be repeated so I hope there is something that can be done between capture and render.

Yes, I'm definitely seeing it in your video, syd. I just don't know what to recommend.

However, you may want to post at the free Community Forum at my web site Muvipix.com. There's a worldwide community of very knowledgeable photographers and videomakers there, and I'm sure they will have some good ideas.
